本发明涉及高效的长管子所用弯曲装置，所述管子由金属制造，例如为钢管、不锈钢管、铜管、钛管及铝管。 The present invention relates to a highly efficient long tube of the folding means, the pipe made of metal, for example steel, stainless steel, brass, titanium and aluminum tubes.
例如公开于JP-8-B-29358号专利中的压模铸件所涉及的具有左组件与右组件的双重折弯模(double bender)，有人按常规是作为以上述类型的弯曲装置(折弯装置)提出了的。 E.g., as disclosed in JP-8-B-29358 in patent No. die casting involved double bending mold having a left component and the right component (double bender), was conventionally used as the above-described type is the bending means (bending means) made of. 在右组件与左组件构成的双重弯曲类型折弯模中，一个弯曲组件(bending unit)机构具有单独结构，且被布置成相对于长管子的水平位置为可自由上下移动的，该长管子被支撑着，而且有一个卡盘机构部分(chuck mechanismportion)与顺着来回方向在活动底座上操作的喂送机构互锁，同时，所述活动底座被布置成能够顺着右边方向和左边方向平行移动的。 In the double bending type bending mode, the right and left components of the assembly, one bending assembly (bending unit) mechanism having a separate structure, and arranged with respect to the horizontal position of the length of the tube to be freely movable up and down, the elongated tube is supporting, and has a chuck mechanism section (chuck mechanismportion) and back and forth along the feed direction of the interlocking mechanism on the active operation of the base, while the movable base are arranged to be along the right and left direction of the parallel movement direction a.
另外，作为另一种已知管子弯曲装置，也有人提出了一种管子弯曲装置，在该装置中，弯曲是为多个将要处理的位置而执行的，这些位置顺着管子轴线中心的方向、顺着符合于相应设置的预定各自预定弯曲方向而设置。 Further, as another known pipe bending apparatus, it was proposed a pipe bending apparatus, in the apparatus, a plurality of bending is for the location to be processed and executed, these positions along the direction of the center axis of the tube, down the line with the corresponding set of predetermined respective predetermined bending direction setting. 此种装置包括一个管子扭曲组件(twist unit)和一个管子弯曲组件，所述管子扭曲组件用于把所处理管子的末端夹住，使管子在其轴线中心周围转动以便设置预定处理方向，并顺着轴线中心的方向移动管子以便把管子设置在预定处理位置上；而所述管子弯曲组件用于在预定角度上夹持及转动所处理管子以便执行弯曲，该管子弯曲组件能够顺着所处理管子的纵向方向移动。 Such apparatus comprises a tube assembly twist (twist unit) and a tube bending assembly, the tube assembly is used to twist the handle end of the tube clamped, the tube is rotated around its axis in order to set a predetermined process direction, and cis the direction of the axis of the tube in order to move the center of the tube disposed in a predetermined processing position; and said bent tube assembly for gripping and rotating the pipe so as to perform the processing at a predetermined bending angle, bending of the tube assembly can be handled along the tube longitudinal direction. 此种装置通常称为CNC折弯模(见JP-B-8-29358号、JP-A-9-308918号、JP-A-9-29346号、JP-A-7-232219号及JP-B-8-9063号专利)。 Such devices are generally referred CNC bending mold (see JP-B-8-29358 number, JP-A-9-308918 number, JP-A-9-29346 number, JP-A-7-232219 and No. JP- patent No. B-8-9063).
然而，在常规的管子弯曲装置中，由至少一个折弯模，还有一件因管子被压靠在折弯模圆周表面上就在该圆周表面上按预定角度使所处理管子转动以便执行弯曲的夹具以及一个反作用力接纳辊所组成的管子弯曲组件，由于惟独只使用各自弯曲方向上的折弯模而导致弯曲半径受到限制，且由于反作用力接纳辊因不会相对于夹具转动致使该辊没有弯曲功能而导致所述管子弯曲组件仅被限制为拉弯，该夹具是按预定角度沿着折弯模圆周表面转动以便执行弯曲的。 However, in the conventional tube bending apparatus, by at least one bending mold, as well as a result of the pipe is pressed against the circumferential surface of the bending mold in a predetermined angle to the circumferential surface of the pipe so that the handle is rotated so as to perform the bending of jig and a tube bending assembly consisting of a reaction force receiving rolls, but only due to the use of only the respective bending direction of the bending mold resulting bend radius is limited, and because the reaction force due to not receiving rolls rotate with respect to the jig so that the roller does not bending the tube bending function resulting assembly is limited to only the bending, the clamp is at a predetermined angle along the circumferential surface of the bending mold is rotated in order to perform bending. 因此，所述管子弯曲组件就没有压弯功能以便借助于夹具而以被夹持(被固定)的管子来使管子弯曲。 Thus, the bending tube bending assembly, there is no function and so as to be clamped by the jig (fixed) of the tube to the tube bend. 所以，在常规装置的情况下，某个管子折弯角度或扭曲角度就导致扭曲操作大量位移，且因此就与反作用力接纳辊一侧上的组件冲突，或者发生此种冲突，从而在某些情况下使整个所处理的弯曲均不能借助于所述装置的组件而执行。 Therefore, in the case of the conventional apparatus, a twist angle of the pipe bend angle or a large number of displacement led to distort the operation, and therefore the reaction force receiving member on the roller side of conflict, or occurrence of such a conflict, so that in some so that the whole bending process can not be performed by means of assembly of the apparatus case. 相应地，就要用多个装置来在某些产品的情况下执行弯曲。 Accordingly, it is necessary to use a plurality of apparatus to perform the bending in the case of certain products. 这样必然增加处理量，且导致弯曲时间不能缩短这一缺点。 This will increase the amount of processing time can be shortened and bent leads this shortcoming.
另外，当把管子折弯直至后续弯曲平面稳固之后而在管子扭曲角度大时(当此角度为90度至180度时)，常规装置就要求有扭曲时间。 Further, when the follow-up to bend the tube bending plane and solid after the twist angle of the tube is large (when the angle of 90 degrees to 180 degrees), the conventional apparatus requires time with a twist. 尤其在弯曲处理量大的情况下，以及已被弯曲的管子长的情况下，扭曲管子所用高速会导致其形状变化，以致使弯曲形状出错，因而就应当以低速扭曲管子。 Especially in the case of large bending process, and has been bent down pipe is long, the twist of the tube with a high speed can cause changes in the shape, a curved shape to cause an error, and therefore should be a low speed twisted tubes. 这样就导致需要长时间来扭曲管子这一缺点。 This results in distortion of the tube takes a long time to this shortcoming. 本发明就是为了克服常规装置中的上述缺点，并提供一种管子弯曲装置，其包括一对弯曲组件，所述弯曲组件具有拉弯功能与压弯功能之一，或此两种功能皆具备，所述管子弯曲装置提供一个带有垂直平面转动机构的弯曲组件，从而能够在所有处理中均在装置的一个组件中进行弯曲。 The present invention is to overcome the above mentioned disadvantages of the conventional apparatus, and to provide a tube bending apparatus, which includes a pair of deflection assembly, the deflection assembly having a bending function and the function of bending, or the two functions are provided, The pipe bending apparatus of a bending assembly with a vertical plane of the rotation mechanism, which can both be bent in an assembly of the apparatus in all treatments.
符合本发明的管子弯曲装置是这样一种管子所用弯曲装置，其包括：至少一个折弯模；一个夹具，其通过所处理管子被压靠在折弯模圆周表面上，在该圆周表面上按预定角度转动以便执行弯曲；以及一个反作用力接纳辊；所述管子所用弯曲装置还包括：活动类型的管子弯曲组件，其能够顺着所处理管子的纵向方向移动，此组件或是一个固定类型的管子弯曲组件；以及一个管子扭曲组件，该组件按预定角度自由转动，以所处理管子的中心为轴线中心，且该组件能把所处理管子移动到对应于弯曲形状的位置上，其中管子弯曲组件的反作用力接纳辊制造成可与折弯模及夹具同心转动，从而使所处理管子的拉弯功能与压弯功能当中的至少一个功能会达到，且所述管子弯曲组件在垂直平面上可绕平行于所处理管子的轴线中心的轴线转动，从而在进行管子扭曲操作时，可减少位移量。 Pipe bending apparatus consistent with the present invention is used in a pipe bending apparatus, comprising: at least one bending die; a jig is pressed against the tube by the handle on the circumferential surface of the bending mold, press on the circumferential surface predetermined rotational angle so as to perform the bending; and a reaction force receiving roller; said tube by folding means further comprising: Active Type of tube bending assembly, which is movable along the longitudinal direction of the tube being processed, this type of component or a fixed tube bending assembly; and a tube twist assembly which is free to rotate by a predetermined angle to the center axis of the handle is the center of the tube, and the tube assembly can move the handle to a position corresponding to the curved shape, wherein the tube bending assembly The reaction force receiving rolls are made movable concentrically with the rotatable bending die and clamp, so that the processing at least one function will reach the tube bending and press bending function among functions, and the tube assembly is bent in a vertical plane is rotatable about axis parallel to the axis of rotation of the processing center of the pipe, thus the tube when twisted during operation, can reduce the amount of displacement.
另外，管子所用弯曲装置的特征在于：管子弯曲组件与管子扭曲组件二者当中的至少一个组件能够移动。 In addition, the tube bending apparatus comprising: a tube assembly and the bending of both tube distortion components among the at least one component capable of moving.
在本发明中，配置了用于压弯的组件以便可与用于拉弯的组件同心地转动，让所处理管子借助于用于压弯的组件而顺着相反方向被弯曲，配置了在垂直平面上可绕平行于所处理管子的轴线中心的轴线转动的管子弯曲组件，可使在扭曲所处理管子的操作中所处理管子的位移量减少。 In the present invention, configured for a press brake assembly so as to be rotatable concentrically with the bending of the components used, so that the handle assembly for a press brake by means of the tube and is bent along the opposite direction, is configured in vertical tube deflection assembly axis on a plane parallel to the handle is rotatable about the center axis of the tube, the tube can reduce the processing operations in the amount of displacement of the tube twist processed. 相应地，无论管子弯曲角度或扭曲角度如何，在所处理管子与弯曲装置或地板表面之间，都不会发生冲突，从而在整个处理中，都能在所述装置的一个组件中进行弯曲。 Accordingly, regardless of the angle of the pipe bend or twist angle how, between the tube and the bending apparatus or floor surface treatment, will not conflict, so that the whole process, can be curved in an assembly of the apparatus. 这样，除了进一步改善弯曲不同半径的管子及长管子的准确性与效率之外，还可更为有效地充分实现执行弯曲的功能。 Thus, in addition to further improve the bending radius of the tube and different accuracy and efficiency of the long tube, they can also be more effective in achieving the full implementation of bent functions. 另外，顺着相反方向同时转动管子弯曲组件和扭曲组件，可使固定弯曲平面所需时间，为顺着一个方向转动单个组件的情况下所需时间的一半。 Also, while rotating in opposite directions along the tube bend and twist assembly components, the fixing time required bending plane, for the case of a single component along the direction of rotation required for half the time. 这样就会极大地缩短弯曲时间，而且由于不再按大的扭曲角度来扭曲管子，就使已经完成的那部分弯曲不再改变形状，从而就能准确地进行弯曲而不会使弯曲形状出现任何错误。 This will greatly reduce the bending time, and because no large twist angle according to distort the tube, so that part of it has been completed curved shape does not change, and thus can accurately curved shape bending without causing any error.

管子扭曲组件3放置在底座1的上表面上，该底座为管子弯曲组件2所共用，以便使所述扭曲组件顺着所处理管子P的轴线中心的方向而可移动。 Twisted tube assembly 3 is placed on the upper surface of the base 1, the base is common to the component tube 2 is bent, so that the distortion component being processed along the central axis of the pipe P in the direction to be movable. 管子扭曲组件3被布置成借助于驱动电动机3M-1、通过齿条与齿轮机构(rack-and-pinion mechanism)而顺着管子的纵向方向在轨道1-2上可来回移动，所述驱动电动机配置于组件主体3-1上，用于移动扭曲组件。 Tube assembly 3 is arranged to twist by a drive motor 3M-1, by a rack and pinion mechanism (rack-and-pinion mechanism) and along the longitudinal direction of the tube on a track 1-2 can be moved back and forth, the drive motor 3-1 disposed on the unit body, for moving the distortion component. 在组件主体3-1中，直立配置于组件主体3-1上部的固定板3-2的顶部末端被开槽，以便形成锁紧部分3-3，所处理管子P就被锁紧在该部分中。 The top end of the unit body 3-1, upright assembly disposed on the upper body portion 3-1 fixed plate 3-2 is slotted to form a locking portion 3-3, the handle is locked in the pipe P to the portion in. 其中有相似于上述槽痕的槽痕3-5的扭曲板3-4被形成，且其中设立有管子夹持机构，此扭曲板与固定板3-2安装成一体。 Wherein the groove similar to groove tracking marks 3-5 3-4 twisted plate is formed, and in which to set up a pipe gripping mechanism, the twisted plate and the fixed plate mounted integrally 3-2. 扭曲板3-4被布置成借助于扭曲所用电动机3M-2通过齿轮组G而转动的。 3-4 twist plate is arranged by means of a twist motor 3M-2 is rotated via the gear set G is used. 也就是说，被布置成可用扭曲所用电动机3M-2来使所处理管子P按预定角度转动。 That is, is arranged to twist the available motor 3M-2 to make the pipe P is rotated by a predetermined angle for processing.

当所处理管子P的两末端被支撑在管子弯曲组件2与扭曲组件3中时，所处理管子P的扭曲角度就由扭曲组件3的扭曲电动机3M-2所确定。 When processed pipe P is supported at both ends of the tube assembly 2 and the bending distortion component 3, the twist angle of the pipe P treatment distorts the motor 3 is determined by the distortion component 3M-2. 所处理管子P同时被用于夹持管子的缸2-15和夹具2-16所夹持，接着，弯曲组件2中的弯曲操作就开始了。 The pipe P is simultaneously processed for clamping the cylinder tube 2-15 and 2-16 of the clamping jig, and then, the bending operation of the bending assembly 2 begins.
现根据图4至6来说明弯曲操作。 On the basis of Figures 4 to 6 to illustrate the bending operation. 首先，在图4中，所处理管子P顺着箭头α所示方向按预定角度被管子扭曲组件3所扭曲，同时，拉弯臂组件2-5按所指定的拉弯角度借助于安装在弯曲组件底板2-4上电动机2M-4而转动。 First, in FIG. 4, the processing of the tube along the direction indicated by arrow P by a predetermined angle α is 3 twisted tube distortion components, while bending the arm assemblies 2-5 bending angle by means of the installation as specified in bending 2-4 on the base plate assembly to rotate the motor 2M-4. 此时，夹具2-16把所处理管子P压靠在拉弯模2-14的圆周表面上，并按预定角度拉动管子，使其贴靠及沿着该圆周表面，以便执行拉弯(拉弯法)。 In this case, the pipe clamp pressure P 2-16 against bending to the processing on the circumferential surface of the mold 2-14, according to a predetermined angle to pull the tube so that it abuts and along the circumferential surface in order to perform Tension (Pull bending method). 上述拉弯导致所处理管子P的一个末端被预定拉弯，该拉弯对应于扭曲组件3所设定的扭曲角度，并对应于拉弯模2-14及夹具2-16的转动角度。 Bending said one end of the tube leading to the processing P is a predetermined bending, the bending distortion component corresponding to the twist angle of the set 3, and corresponds to the bending mold and fixture 2-16 2-14 rotational angle.
接着，拉弯臂组件2-5及压弯所用组件2-7被分别借助于拉弯所用电动机2M-4及2M-5而在同样的支撑轴2-8周围转动180度，以便被定位于图5所示位置。 Next, the bending arm assembly 2-5 and 2-7 are bent by means of the components used in the respective bending motor 2M-4 and 2M-5 is rotated 180 degrees around the supporting shaft 2-8 of the same, so as to be positioned at position shown in Figure 5. 所处理管子P顺着箭头β所示方向(即顺着与图4所示方向相反的方向)被管子扭曲组件3扭曲预定角度，以执行压弯。 Pipe P along a direction indicated by an arrow β processed (i.e., along the direction opposite to the direction shown in FIG. 4) is twisted tube assembly 3 is twisted by a predetermined angle, to perform the bending. 也就是说，所处理管子P借助于夹具2-16及压力缸2-18而被压靠着拉弯模2-14，同时，安装在压弯所用组件底板2-6上的电动机2M-5被按指定弯曲角度而反向转动。 In other words, the treatment by the jig tube P 2-16 and 2-18 cylinder is pressed against the bending die 2-14, while the motor is mounted on the bending 2-6 backplane components used 2M-5 is bent by a specified angle while the reverse rotation. 此时，按预定角度的转动就由与所处理管子P的外周边所接触的反作用力接纳辊2-16以及压靠在拉弯模2-14圆周表面上的所处理管子P来执行，且因此就执行压弯(压弯法)。 In this case the outer periphery, by rotating it by a predetermined angle and processed in contact with the pipe P of the reaction force is pressed against the receiving roller 2-16 and pull the pipe P to perform processing on the circumferential surface of the bending mold 2-14, and Therefore, the implementation bending (bending method). 这种弯曲导致所处理管子P的一个末端被预定拉弯，该拉弯对应于扭曲组件3所设定的扭曲角度，并对应于拉弯模2-14及夹具2-16的转动角度。 This bending leads to one end of the pipe P being processed is a predetermined bending, the bending distortion components corresponding to the twist angle of the set 3, and corresponds to the rotation angle of bending mold clamp 2-14 and 2-16.
图6显示依靠同时反向转动管子弯曲组件2和扭曲组件3而使所处理管子P弯曲的方法。 Figure 6 shows the reverse rotation of the tube while relying on bending and twisting component assembly 2 3 P leaving the processing method of bending the tube. 具体而言，所处理管子P被管子扭曲组件3顺着箭头γ所示方向按预定扭曲角度扭曲，而弯曲组件2则同时借助于转动所用电动机2M-6顺着箭头δ所示方向按预定角度在转动支撑轴2-8周围被转动。 Specifically, the processed pipe P is twisted tube assembly 3 along a direction indicated by an arrow at a predetermined twist angle γ twisted, bent components 2 simultaneously by means of rotation of the motor along the direction indicated by the arrow δ 2M-6 by a predetermined angle 2-8 rotation around the support shaft is rotated. 在此种条件下，拉弯臂组件2-5借助于安装在弯曲组件底板2-4上的电动机2M-4按指定弯曲角度而被转动。 Under such conditions, the components 2-5 by means of a bending arm bending assembly mounted on the bottom plate 2-4 of the motor 2M-4 specified bend angle is rotated. 此时，夹具2-16把所处理管子P压靠在拉弯模2-14的圆周表面上，并按预定角度拉动管子，使其贴靠及沿着该圆周表面，以便执行弯曲(拉弯法)。 In this case, the pipe clamp pressure P 2-16 against bending to the processing on the circumferential surface of the mold 2-14, according to a predetermined angle to pull the tube so that it abuts and along the circumferential surface in order to perform the bending (bending law). 此种弯曲导致所处理管子P的一个末端被预定拉弯，该拉弯对应于扭曲组件3所设定的扭曲角度，且对应于拉弯模2-14及夹具2-16的转动角度。 Such bending leads to one end of the handle tube P is predetermined bending, the bending distortion components corresponding to the twist angle of the set 3, and the corresponding bending die and fixture 2-16 2-14 rotation angle in. 在所用方法为同时反向转动管子弯曲组件2及扭曲组件3以执行对所处理管子P加以弯曲的情况下，所处理管子P的扭曲角度可设定为大的。 In the method used for the reverse rotation of the tube while bending components 2 and 3 to perform the distortion components of the pipe P to be processed by the curved case, the twist angle of the treated pipe P may be set to large.
另一方面，在图7所示管子弯曲装置中，管子弯曲组件2与管子扭曲组件3二者均安装在底座1上，以便顺着所处理管子P的轴线中心方向可移动，如上文所述那样。 On the other hand, in the pipe bending apparatus shown in Figure 7, the tube 2 and the tube bending assembly twisted assembly 3 both mounted on the base 1, so that the center along the axial direction of the pipe P handle movable, as described above that. 管子弯曲组件2被安装在底座1的上部，该底座为管子扭曲组件3所共用，以便顺着所处理管子P的轴线中心方向可移动，相似于扭曲组件3的情况那样。 Bending the tube assembly 2 is mounted on the upper portion of base 1, the base for the tube distortion components common to 3, in order along the axial direction of the center of the pipe P of the movable handle, similar to the case 3 as distortion components. 布置了管子弯曲组件2的移动机构，以便其借助于用于移动扭曲组件的电动机2M-7，通过齿条与齿轮机构或类似物体而顺着管子的纵向方向在轨道1-2上可来回移动，该轨道为管子扭曲组件3所共用，所述电动机配置在与固定板2-1形成为一体的基座板2-1′上。 Tube assembly is arranged to move the bending mechanism 2, so that its movement by means of twisted assembly for a motor 2M-7, by a rack and pinion mechanism or similar object and along the longitudinal direction of the tube on the rail can be moved back and forth 1-2 The track is a tube distortion components common to 3, the motor is disposed on the fixed plate 2-1 is formed as one of the base plate 2-1 '. 在图7所示管子弯曲装置的情况下，弯曲不仅可由于使管子弯曲组件2和管子扭曲组件3中任何一个组件移动而执行，也可由于同时移动管子弯曲组件2与管子扭曲组件3二者而执行。 In the case of the pipe bending apparatus shown in Figure 7, not only due to bending the tube bending distortion component assembly 2 and the pipe 3 to move to any one of the components is performed, may also be due to the bending assembly 2 while moving the tube with the tube 3 both distortion components and execution.
符合本发明的管子弯曲装置的管子弯曲组件，并非一定要同时具备使所处理管子被拉弯与压弯这两种功能。 Consistent with the present invention, the tube bending apparatus of a tube bending assembly, does not have to bend along with the tube is pulled and bent both functions for processing. 因此，例如可以使用JP-B-8-29358号、JP-A-7-232219号或JP-B-8-9063号专利中所说明的那种弯曲组件，该组件已在上文中予以说明。 Thus, for example, JP-B-8-29358 use number, JP-A-7-232219 or No. JP-B-8-9063 Patent No. kind bending assembly illustrated, the component is to be described in the foregoing. 不用说，所处理管子P的弯曲位置与扭曲角度、弯曲组件的转动角度、扭曲组件以及弯曲组件的移动量，以及符合本发明的管子弯曲装置的此类成分，均被布置成提前输入到自动控制器(其在附图中省略了)中的，从而可以完全自动地执行对所处理管子的弯曲。 Needless to say, the pipe P is bent position with the twist angle being processed, the rotation angle of the bending assembly, distortion components and the amount of movement of the bending assembly, and in line with the pipe bending apparatus of the present invention such ingredients are arranged in advance is input to the automatic the controller (which is omitted in the drawings) in order to be fully automatically performed on the bending processing of the tube.
