叶片、叶轮、涡轮流体机械、叶片的制造方法以及制造装置技术领域 Blades, impellers, turbine fluid machine blade manufacturing method and manufacturing apparatus TECHNICAL FIELD

本发明涉及将例如水等液体作为工作流体的涡轮形流体机械的叶轮以及用于它的叶片、叶轮的制造方法以及叶轮的制造装置,特别是涉及与形式以及流体的种类无关,基于使叶轮板金工加工化的廉价的涡轮形流体机械的叶轮的制造方法。 The present invention relates to a liquid such as water as a working fluid, a turbine and an impeller type fluid machine manufacturing apparatus and manufacturing method for its blade impeller, the impeller, particularly to the form and regardless of the type of fluid, the impeller based sheet metal The method of manufacturing and processing of cheap labor turbo-type fluid machine of the impeller.

背景技术 Background

在涡轮流体机械中,除以水等液体作为工作流体的离心泵以外, 还包括以空气等气体作为工作流体的离心压缩机。 Other than the turbo fluid machines, divided liquid such as water as a working fluid pump, further comprising gas such as air as the working fluid of the centrifugal compressor. 这些涡轮流体机械 These turbo fluid machine

中,作为代表例,有专利文献l (特开平7-167099号公报)所示的涡轮流体机械。 As a typical example, Patent Document l (JP-A-7-167099 Gazette) shown turbo fluid machine.

针对主要构成要素,例如通过图1说明以水作为工作流体的离心泵的情况。 For the main elements, such as to explain the situation with water as the working fluid through a centrifugal pump 1. 离心泵由叶轮6、 7、壳体l、旋转轴2以及电动机(未图示出)等构成。 Centrifugal 6, 7, the housing l, and a motor rotating shaft 2 (not shown) or the like by the impeller. 其中,叶轮6、 7是多片叶片5分别被安装在凸台3 和护罩4之间的构造,它通过旋转轴2旋转,据此,赋予流体能量。 Wherein the impeller 6, 7 are a plurality of blades 5 are mounted on the boss structure 4 between 3 and shroud 2 is rotated through the rotary shaft, whereby imparting fluid energy. 即,通过叶轮的旋转,向从吸入口8吸入的水付与离心力,通过安装在叶轮出口的引导叶片,使流体的流动的方向合理化。 That is, by rotation of the impeller, the suction from the suction port 8 and the centrifugal force of the water to pay, through the installation of the guide vanes of the impeller outlet, so that the flow direction of the fluid rationalization.

罔为离心泵中的轴流泵有效地将泵旋转能变换为流体的运动能, 所以,所具备的特长是叶轮的叶片相对于流路方向具有扭转。 Indiscriminately to the axial flow centrifugal pump rotational energy effectively transformed into a moving fluid can, therefore, possess specialty is the impeller blade with respect to the flow direction has reversed.

关于离心压缩机,基本的构成要素与离心泵同样,但是,例如如图2所示,有将在凸台3安装了多个叶片5a、 5b的叶轮6、 7安装在同轴2上的多级型,但在该多级型压缩机中,各叶轮的叶片形状不同。 About centrifugal compressors, centrifugal basic constituents Similarly, however, such as shown in Figure 2, there will be 3 bosses install multiple blades 5a, 5b of the impeller 6, 7 is mounted on the coaxial 2 more -stage type, but in the multistage compressor, each impeller blade shape is different. 特别是用于压缩机的叶片其叶片面由大致直线的线素设计。 In particular for a compressor blade leaf surface by a substantially straight line element design.

作为涡轮流体机械的制造方法,就叶轮而言,通过在铸造后进行机械加工来制造。 As a method for turbo fluid machine, the impeller is concerned, by machining after casting to produce. 另外,在要求高度的叶片形状精度的情况下,也有通过切削加工制造叶轮整体的情况。 In addition, at the request of the height of the blade case shape accuracy, but also the manufacture of the impeller by cutting the overall situation. 再有,在叶轮的叶片为三维扭转形状的情况下,使用了专门对应各叶片的三维总金属模的冲压加工被应用。 Further, in the case of a three-dimensional twist impeller blade shape, using a special metal mold corresponding to the total of each three-dimensional blade press working is applied.

针对壳体,使用板金工加工手法,所述板金工加工手法是通过焊接等将冲压加工的钢板性的叶片接合在将钢板辊压成型的内外筒。 For housing, the use of panel beaters and processing techniques, processing techniques through the panel beaters, sheet steel of the press working such as welding steel roll forming in the inner and outer tube.

在现有的涡轮流体机械中,特别是压缩机的叶轮是在锻造后由机械进行切削加工,但是,在大直径零件中,由于材料利用率降低,所以,该对策是制造上的技术课题。 In the conventional turbo fluid machines, in particular of the impeller of the compressor is performed after cutting by the forging machine, however, the large diameter part, due to the reduced material utilization, therefore, the countermeasure is manufactured on a technical problem. 另外,在板金工加工构造的叶轮的制作中,虽然所使用的是使用了与各叶片相吻合的专用的三维总金属模的冲压成型,但是,在制作成本中金属模费用所占的比例大,是叶轮的板金工加工化的课题。 Further, in the production of panel beaters impeller processing structure, although use is the use of each blade coincides with the total specific three-dimensional mold stamping molding, however, a large cost in the production cost of the metal mold proportion It is the subject of panel beaters impeller machining. 同样的课题也存在于斜流泵的叶轮以及壳体的制作中,要求采用对策。 The same problem also exists in the production of mixed flow impeller and pump housing, require the use of countermeasures.

另外,就壳体的制造方法而言,虽然由于引导叶片是替代三维总金属模由板金加工机制作,抑制了金属模费用,但是,在以往的板金加工机中施加三维的扭转在原理上是不可能的,所以,不适合叶轮的制作。 Further, the method of manufacturing the housing, although alternative since the guide vanes are always three-dimensional mold made by a sheet metal processing machine, the mold cost is suppressed, however, a three-dimensional twist is applied in the conventional sheet metal processing machine in principle are impossible, therefore, not suitable for the production of the impeller. 因此,以低成本使叶轮板金工加工化是重要的技术课题。 Thus, at low cost so that the impeller panel beaters processing is an important technical problem.

另外,作为叶片的三维成型的课题,还有下述课题。 In addition, the subject of a three-dimensional shape of the blades, as well as the following topics. 在通过上下模冲压成型具有三维扭转的叶片的情况下,在材料和金属模局部接触的成型初始,由于材料没有被限制在金属模之间,所以容易偏离。 In the case of forming a three-dimensional twisted blade by the upper and lower die stamping, molding material and the initial partial contact with the metal mold, it is limited since the material is not between the metal mold, it is easy to deviate. 因此,在以往的叶片的制作中,预估偏离,使用与最终的叶片相比有富余的材料进行冲压成型,从成型后的材料切出与最终形状的叶片面最接近的区域。 Thus, the production of a conventional blade, the estimated deviation using blade compared with the final surplus material press-molded, the molded material was cut out and the final shape of the blade surface area closest. 但是,海水泵等在特殊环境下使用的叶轮的材料一般高价,抑制材料利用率是课题。 However, the sea water pumps for use in special circumstances impeller materials are generally expensive, suppressing material utilization is the subject. 因此,抑制冲压成型时的材料偏离也是重要的技术课题。 Thus, when press molding suppressing material is an important technical problem deviates. 再有,由于每一片叶片的形状精度不一致而产生叶轮的振动是涡轮流体机械运转时的噪音的原因,叶轮的组装精度极其重要。 Further, since each piece of inconsistent shape precision and vibration of the impeller blades is reason turbo fluid machine noise during operation, the impeller assembly accuracy is extremely important.

本发明针对上述的课题,考虑涡轮流体机械的低成本化,以提供叶轮的制造方法以及制造装置和可应用它们的叶片以及叶轮为目的。 The present invention addresses the above problems, consider the cost of the turbo fluid machine to provide a method and apparatus for manufacturing the impeller and the impeller blades and to apply them for the purpose. 另外,以提供可高精度成型叶轮的叶片为目的。 Further, in order to provide a high accuracy impeller blades shaped for the purpose.

在步骤S8中,将使上下冲头lla、 llb和材料IO表面一致的状态作为工序的初始位置,从此状态开始,调整位移以及倾斜,直至使上下的冲头达到规定的扭转角度和弯曲行程。 In step S8, enable upper and lower punches lla, llb and material status IO consistent surface location as the initial step, starting from this state, displacement and tilt adjustment until the upper and lower punches to achieve the required twist angle and bend trip. 具体地说,对图7中的冲头控制用的液压缸61a、 61b进行位移控制。 Specifically, FIG. 7 punch control hydraulic cylinders 61a, 61b displacement control. 通过该位移控制,材料10被成型为在步骤S4中读取的弯曲角度和扭转角度。 By this displacement control, material 10 is formed into a read in step S4 bending angle and twist angle.

在步骤S9中,使上下冲头lla、 llb恢复到原点,使上下冲头离开材料。 In step S9, the upper and lower punches lla, llb return to the origin, the upper and lower punches to leave the material. 在这里,上下冲头的原点例如在图7的装置构成中,只要是冲头控制用的液压缸61a、 61b分别为最缩短的位置即可。 Here, for example, the origin of the upper and lower punches apparatus configured in FIG. 7, as long as the plunger with the control cylinder 61a, 61b are most shortened position. 在步骤SIO 中,开放压板,使材料为非限制状态,成为材料能向下一个工序移动的状态。 In step SIO, the open plate, so that the material is non-regulated state, becoming the material can move to the next step of the state.

在步骤S11中,将工序号n更新为下一次加工的补片的工序号。 In the step S11, the operation number n is updated to the next machining operation number of patches. 因为通常下一次加工相邻的补片,所以,更新后的n为加l的值。 Because usually the next working adjacent patch, so, n l updated to add value. 在步骤S12中,判定全部工序是否结束。 In step S12, it is determined whether or not all the processes end. 若所有的工序完成,则结束。 If all of the process is completed, the end. 在所有的工序没有完成的情况下,再次返回到步骤S4,依次进行剩下 In the case of all the processes is not completed, once again returns to step S4, the turn remaining
