[0043](切断工序) [0043] (cutting step)

[0044] 如图2 (1)所示,在使挡块11下降了的状态(即,隔断供给线L的状态),且将插入夹钳9以及前端夹钳10均打开了的状态下,使进给装置5驱动,将原料管材Pl送出,直至如图2 (2)所示,原料管材Pl的前端通过刀具装置8、插入夹钳9、前方导向器13b以及前端夹钳10,碰撞挡块11。 [0044] FIG. 2 (1), in the stopper 11 is lowered by the state (that is, cut off the supply line L state), and the insert 9 and the front end of the clamp jaws 10 are opened state, driving the feed device 5, the feed pipe Pl sent until Fig. 2 (2), the distal end of the feed pipe Pl by cutter means 8, 9 clamp insert, in front of the guide clamp 10 and the front end 13b, the collision block Block 11.

[0045] 然后,在原料管材Pl碰撞到挡块11后,停止进给装置5的送出,如图2C3)所示, 关闭插入夹钳9以及前端夹钳10,将原料管材Pl固定。 [0045] Then, the raw material pipe Pl stopper 11 after a collision to stop feeding out device 5, as shown in Figure 2C3), a closed distal end is inserted the clamp 9 and clamp 10, the feed pipe Pl fixed. 接着,使刀具装置8工作,将原料管材Pl在规定的位置切断。 Subsequently, the tool unit 8 to work, the material pipe is cut at a predetermined position Pl. 此时,刀具装置8为使切断管P2成为规定的长度,而被设置在离开挡块11规定距离的位置。 At this time, the cutter device 8 to the cutting pipe P2 becomes a predetermined length, and is disposed at a position away from the stopper 11 a predetermined distance.

[0046] (插入工序) [0046] (insert process)

[0047] 在切断结束后,如图3(1)所示,使挡块11上升,将供给线L开放,打开插入夹钳9。 [0047] After the end of the cut, as shown in Figure 3 (1), so that the stopper 11 rises, the supply line L is open, the clamp opening 9 is inserted. 而且,如图3(所示,使底座7向折弯机部3侧移动,然后,关闭插入夹钳9。接着,如图3 (3)所示,打开前端夹钳10,在底座7上,使保持了切断管P2的状态的插入夹钳9进一步向折弯机部3侧移动。 Further, in FIG. 3 ( shown, so that the base 7 to move the bending portion 3 side, and then close the clamp insert 9. Next, FIG. 3 (3), the open front end of the clamp 10, the base 7 on the holding of the state cut off the pipe P2 is inserted into the clamp 9 moves further towards 3 side bending machine unit.

[0048] 此时,弯曲装置12的夹模12b以及压模12c均打开,切断管P2被插入弯曲装置12 的恰当位置。 [0048] In this case, the bending device and the clamping die 12b 12c 12 are opened, P2 cutting tube 12 is inserted into the proper position of the bending apparatus. 在切断管P2的插入完成后,关闭夹模12b,由成形辊1和夹模12b夹入并固定切断管P2。 After disconnecting the tube insertion is completed P2, and close clamping 12b, by the forming rolls 1 and clamping 12b sandwiched and fixed cutting pipe P2. 另外,在切断管P2被插入弯曲装置12时,由芯杆装置15将芯杆1插入切断管P2内的规定的位置(弯曲加工部分的内侧)。 Further, the cut pipe P2 is inserted into the bending means 12, the mandrel 15 by the mandrel means 1 pipe P2 is inserted within a predetermined cutting position (inner bending portion).

[0049] 接着,如图3 (4)所示,打开插入夹钳9,使底座7向进给装置5侧移动,返回切断时的位置。 [0049] Next, FIG. 3 (4), the clamp opening 9 is inserted so that the base 7 to move the feed device 5 side, the return position when cut. 另外,插入夹钳9也在底座7上向进给装置5侧移动,返回切断时的位置。 In addition, the insert 7 clamp base 9 are 5 to feed the mobile device side, the return position when cut. 最后, 使挡块11下降,成为隔断供给线L的状态。 Finally, the stopper 11 is lowered, the supply line L becomes cut off state.

[0050](弯曲工序) [0050] (bending process)

[0051] 如图4(1)以及图4(2)所示,一面由弯曲装置12的压模12c按压切断管P2的前端侧,一面使夹入切断管P2的后端侧并进行固定的成形辊1和夹模12b旋转(正转)规定角度,据此,进行切断管P2的弯曲加工,制造管制品P3。 [0051] FIG. 4 (a) and 4 (2), the pressing face 12c by the bending die 12 of the tube distal end side of the cutting means P2, the cutting side so that the rear end side of the clip into the tube and fixed P2 1 forming roll 12b and clamping the rotation (forward) at a predetermined angle, pursuant to cut the pipe P2 bending, manufacture pipe products P3. 然后,在弯曲加工结束后,如图4(3)所示,打开夹模12b以及压模12c,解除管制品P3的固定,由芯杆装置15使芯杆1 返回原来的位置,如图4(4)所示,使卸料装置14向弯曲装置12侧移动。 Then, at the end of the bending 4 (3), open the folder mode 12b and die 12c, unfixed tube products P3 by the mandrel device 15 so that the stem 1 return to the original position, shown in Figure 4 (4), so that the discharge device 14 to move to 12 side bending devices. 这样一来,管制品P3从弯曲装置12被推出,并被排出,由未图示出的运送构件向装置外运送。 As a result, pipe products P3 from bending device 12 is pushed out, and was discharged from the carrying members (not shown) to the outside of the device handler. 然后,使卸料装置14向原来的位置返回,另外,使成形辊1和夹模12b反旋转,恢复到原来的位置。 Then, the discharge device 14 is returned to its original position, in addition, the forming roll 12b 1 and clamping counter-rotating, restored to its original position.

[0052] 有关本实施方式的管折弯机1通过未图示出的控制装置,全自动地执行上述的切断工序、插入工序以及弯曲工序。 [0052] For the present embodiment, a pipe bending machine by a control device not shown, performs the above-described automatic cutting step, the insertion step and the bending step. 而且能够通过反复进行由上述的切断工序、插入工序以及弯曲工序构成的一系列工序,对原料管材Pl实施弯曲加工,连续地制造管制品P3。 But also by repeating the above cutting step, the insertion step and the bending step consisting of a series of processes, the raw material pipe bending Pl embodiment, the tube continuously manufactured article P3. 但是,各工序不是按顺序执行,在第二循环以后,切断工序与其前一循环的弯曲工序同时执行。 However, instead of performing the respective steps in sequence, after the second cycle, the previous cycle with its cutting step of bending operations performed simultaneously. 即, 在弯曲工序在折弯机部3被执行的期间,在刀具部2执行下一循环的切断工序。 That is, during the bending process the bending portion 3 is executed, the tool part 2 the next cycle of the cutting process.

[0053] 在图6所示的以往的管折弯机31中,因为原料管材Pl被插入到弯曲装置42内后, 执行切断工序,所以,在弯曲工序在折弯机部33被执行的期间,在刀具部32不能执行切断工序,只能待机。 [0053] In view of a conventional tube bending machine 31 shown in Figure 6, because Pl is inserted into the feed pipe after the bending means 42, perform the cutting step, therefore, in the bending machine during the bending process portion 33 to be executed In the cutter unit 32 can not perform the cutting process, can only stand. 因此,如图5(2)所示,不得不在插入工序结束后,执行切断工序,在切断工序结束后,执行弯曲工序,在弯曲工序结束后,执行下一循环的插入工序。 Thus, in FIG. 5 (2), after the insertion process has to perform the cutting step, after the cutting step, a bending step, after the bending step, the next step of the cycle is inserted.

[0054] 与此相对,在本实施方式的管折弯机1中,从图5(1)也可以看出,在弯曲加工在折弯机部3进行的期间,在刀具部2执行下一循环的切断工序,另外,由于切断工序所需时间和弯曲工序所需时间大致相同,所以,在算出第二循环以后各循环的所需时间(由一次切断工序、一次插入工序以及一次弯曲工序构成的一系列工序所需时间)时,没有必要算上切断工序的所需时间,即,能够以插入工序的所需时间和弯曲工序的所需时间的合计值作为各循环的所需时间,相对于图6所示的以往的管折弯机31,能够缩短切断工序所需时间的量(约为整体的30〜40% )。 [0054] In contrast, in this embodiment, tube bending machine from FIG. 5 (1) can also be seen in the bending machine during the bending portion 3, and in the next tool part 2 cutting step of the cycle, additionally, since the cutting step and the time required for the time required for the bending process is substantially the same, therefore, the time required is calculated after the second cycle of each cycle (the first cutting step, a step and a bending step of inserting constitute When the time required for a series of steps), there is no need to count the time required for the cutting step, i.e., the total value of the time required can be inserted and the time required for the bending process as the time required for each step of the cycle, the relative conventional tube bending machine 31 shown in FIG. 6, it is possible to shorten the amount of time required for the cutting process (about 30 to 40% overall).

[0055] 另外,在以往的管折弯机31中,由于是在将原料管材Pl插入弯曲装置42时,通过使其前端碰撞卸料装置44来进行定位,所以,存在在原料管材Pl的前端产生变形或在卸料装置44产生破损或磨损的问题,但在本实施方式的管折弯机1中,没有必要在将切断管P2 插入弯曲装置12时,使其前端碰撞卸料装置14,能够避免端部变形、卸料装置14的破损这样的问题,另外,能够降低磨损量。 [0055] Further, in the conventional tube bending machine 31, because it is inserted in the feed pipe Pl bending means 42, so that the front-end collision by discharge means 44 to locate, therefore, the presence of the distal end of the feed pipe Pl deformation or breakage or wear problems at the discharge device 44, in this embodiment, tube bending machine, there is no need to cut pipe P2 is inserted bending device 12 to the front end collision discharge means 14, deformation of the end portion can be avoided, such a problem of breakage of the discharge device 14, Further, it is possible to reduce the amount of wear.
