[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] 2 (1), the stopper 11 is lowered in a state shown in FIG (i.e., cut off the supply line L state), and the lower jaw 9 and the distal end is inserted into the clamp 10 are opened state, driving the feed device 5, the raw material feeding pipe Pl until 2 (2), the front end by the feed pipe Pl cutter device 8, 9 is inserted into the jaw, the front end of the front guide 13b, and the clamp 10, the collision speed 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。 After [0045] Then, the raw material collides with the stopper Pl pipe 11, stops feeding out device 5, FIG. 2C3), a closed distal end is inserted into the clamp 9 and clamp 10, the feed pipe is fixed Pl. 接着,使刀具装置8工作,将原料管材Pl在规定的位置切断。 Next, the tool working means 8, the feed pipe 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, is disposed at a position separated from the stopper 11 a predetermined distance.

[0046] (插入工序) [0046] (inserting step)

[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] At the end of the cutting, as shown in FIG. 3 (1), the stopper 11 rises, the supply line L is open, the clamp opening 9 is inserted. 而且,如图3(¾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, as shown in FIG. 3 (¾, 7 is moved so that the base portion to the bending machine 3 side, and then, to close the clamp insert 9. Next, as shown in FIG. 3 (3), the front end of the clamp 10 is opened, the base 7 on-off state holding the pipe P2 is inserted into the jaw 9 moves further bending machine 3 side portions.

[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] At this time, the bending die means 12b and 12c clamp die 12 are opened, cutting off the bent pipe P2 is inserted into an appropriate position of the apparatus 12. 在切断管P2的插入完成后,关闭夹模12b,由成形辊1¾和夹模12b夹入并固定切断管P2。 After completion of cutting the pipe P2 is inserted into the closed mold clamping 12b, and the forming rolls 1¾ Clamp 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1¾插入切断管P2内的规定的位置(弯曲加工部分的内侧)。 Further, when cutting the pipe P2 is inserted into the bending apparatus 12, the core rod 15 from the stem portion of the cutting means 1¾ predetermined position P2 in the tube (the inner portion of the bending).

[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, as shown in FIG. 3 (4), inserted into the clamp opening 9, so that the base 7 to move the feed device 5 side, returned cutting position. 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。 Further, the jaw 9 is also inserted into the chassis 7 side to the feeding device 5 is moved to return the cutting position. 最后, 使挡块11下降,成为隔断供给线L的状态。 Finally, the stopper 11 drops, the state of blocking the L supply line.

[0050](弯曲工序) [0050] (bending step)

[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1¾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 mold tube 12 distal the cutting apparatus side P2 of the cutting side so that the rear end side of the sandwich pipe P2 and fixing clamp 1¾ forming roll 12b and the rotation (forward rotation) by a predetermined angle, whereby the bending of the cutting pipe P2, pipe manufacturing 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1¾ 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, after the bending, as shown in FIG. 4 (3), the opening 12b and the clamp die stamper 12c, the fixed tube product P3 is released from the core rod 15 and the rod bar 1¾ means returns to the original position, as shown in FIG 4 (4), the discharge means 14 moves toward the bending device 12. 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。 Thus, the tube is pushed from the article P3 12 bending device, and is discharged, by courier member (not shown) to the outside of the device. 然后,使卸料装置14向原来的位置返回,另外,使成形辊1¾和夹模12b反旋转,恢复到原来的位置。 Then, the discharge means 14 is returned to the original position, Further, the forming roll 1¾ Clamp 12b and reverse rotation, return to the 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, the pipe bending machine by a control device (not shown), perform the above 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 step of inserting step and a series of curved step configuration, 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, each step is not executed sequentially, after the second cycle, the cutting step of the previous cycle to its bending step 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 step of bending portion 3 is executed, the cutting step tool part 2 performs the next cycle.

[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] 31, since the feed pipe Pl is inserted into the bending device 42, a cutting step performed in a conventional tube bending machine shown in FIG. 6, therefore, in the bending process portion 33 during bending machine executed in the cutter portion 32 can not perform the cutting step, 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 step had performed the cutting step, after the cutting step, the bending step performed after completion of the bending step, the insertion step of the next cycle.

[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] On the other hand, in an embodiment of the bending machine according to the present embodiment, may be seen from FIG. 5 (a), in the bending section during bending machine 3, the tool part in the execution of the next 2 the cutting step of the cycle, further, since the time required for the desired bending process and cutting process time is substantially the same, therefore, the time required for the second and subsequent cycles is calculated for each cycle (once by the cutting step, a step of inserting step and a curved configuration 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 can be required to process time required for the insertion and bending process as the time required for each cycle, the relative conventional tube bending machine shown in FIG. 631, the cutting step can be shortened amount of time (about 30 to 40% of the total).

[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, since the feed tube is inserted Pl bending means 42, 44 so as to locate a front end collision by discharge means, therefore, the presence of material at the front end of the pipe Pl deformation or breakage or wear problems at the discharge means 44, but in the tube bending machine of the present embodiment 1, when it is not necessary to cut the pipe P2 is inserted into the bending means 12, 14 so that a front end collision discharge means, possible to avoid deformation of the end portion, the discharge is a problem of breakage apparatus 14, further, it is possible to reduce the amount of wear.
