It is characterized by being driven so as to be pressed against.

  According to this configuration, since the power generation member has a bag shape, the power generation member is small when the fluid is discharged, and can be easily disposed in a narrow place. Thereby, the layout space between the processing force application member and the power generation member can be reduced.

  Further, by supplying a fluid to the power generating member and expanding it, the working force applying member is pressed against the work piece, and thereby it is possible to apply an external force to the work piece so as to obtain a predetermined shape. .

Will be driven. Accordingly, for example, it is possible to press both the first processing force application member and the second processing force application member against the workpiece using one power generation member.

  A third invention is the first or second invention, wherein the work piece is configured to perform a first bending process and a second bending process to obtain a final shape after the first bending process. The power generation member performs at least the first bending process.

  According to this configuration, after the workpiece is subjected to the first bending process, the second bending process is performed to obtain a final shape. That is, at the time of the first bending process, the process up to the final shape may be performed, so that the process can be performed with a relatively small force. Therefore, the expansion force of the power generation member is small, and the load applied to the power generation member is small.

  According to the first and fifth inventions, the power generating member is formed in a bag shape capable of supplying and discharging fluid, and the processing force applying member is pressed against the workpiece by the expansion force generated by supplying the fluid. The force applying member and the power generating member can be combined in a compact manner. Thereby, since various workpieces can be processed, the applicable range of the processing apparatus can be expanded.

  According to the second invention, since the power generation member is disposed between the first processing force application member and the second processing force application member, a plurality of processing force application members are moved using one power generation member. Can do. Thereby, it can be put together more compactly.

  According to the third aspect of the invention, since the first bending process for processing the workpiece until it reaches the final shape is performed using the power generation member, the load applied to the power generation member can be reduced, and the power generation member can be reduced. Can be obtained with an inexpensive structure.

  According to the fourth aspect of the invention, when the window opening of the automobile is hemmed, the processing force application member and the power generation member are arranged inside the window opening. The effect of the present invention that can be made compact is more remarkable.

  The door main body side bag 23 is configured by laminating a large number of sheet-like members having high airtightness and flexibility, and a reinforcing material such as Kevlar fiber so as not to burst even when the inside is filled with compressed air. It is reinforced with. When air is discharged from the door main body side bag 23, the thickness becomes about 10 mm to 20 mm. On the other hand, if compressed air is supplied to the door main body side bag 23, thickness will be about 70 mm-about 90 mm. In addition, this numerical value is an illustration and it can be set as the bag of arbitrary shapes.

  A bag receiving member 10 a that receives the door main body side bag 23 is fixed to the upper surface of the base 10. A surface 10b of the bag receiving member 10a facing the slide member 22a extends in a direction substantially orthogonal to the guide direction of the guide rail 22b. The door main body side bag 23 is disposed between the surface 10b of the bag receiving member 10a and the slide member 22a.

  Since the door main body side bag 23 is thin as described above in a state where the compressed air is discharged, the door main body side bag 23 can be easily disposed even if the space between the bag receiving member 10a and the slide member 22a is narrow. Thereby, the door main body side processing part 11 is gathered compactly.

  A compressed air supply / exhaust pipe 40 is connected to the door main body side bag 23, and compressed air is supplied into the door main body side bag 23 through the supply / exhaust pipe 40. The air supplied to is discharged.

  A pump 43 that supplies compressed air is connected to the supply / discharge pipe 40.

  Therefore, when the rod 34b of the sash side hydraulic cylinder 34 contracts, the engaging portion 34c engages with the upper surface of the sash punch 31, and the sash punch 31 moves downward against the urging force of the floating spring 32e. It will be.

  The sash side bag 33 is a power generation member for moving the sash punch 31 and pressing it against the workpiece 110a (shown in FIG. 4). The sash side bag 33 is driven so as to press the sash punch 31 against the workpiece 110a by the expansion force.

  A surface 10c of the bag receiving member 10a facing the slide member 32a extends in a direction substantially orthogonal to the guide direction of the guide rail 32b. That is, the surface 10c is inclined so as to be located on the left side of the processing apparatus 1 as it goes upward. The sash side bag 33 is disposed between the surface 10c of the bag receiving member 10a and the slide member 32a.

  Since the sash side bag 33 is thin as described above in a state where the compressed air is discharged, the sash side bag 33 can be easily arranged even if the space between the bag receiving member 10a and the slide member 32a is narrow. Thereby, the sash side process part 12 is gathered together compactly.

  A compressed air supply / exhaust pipe 41 is connected to the sash side bag 33, and compressed air is supplied into the sash side bag 33 through the supply / exhaust pipe 41, and is also supplied into the sash side bag 33. Air is exhausted.

  The supply / discharge pipe 41 is connected to the supply / discharge pipe 40 and is switched between a communication state and an open state by a common air pressure control valve 42.

  As shown in FIG. 3, the control device 14 is connected to a start button 59 that is operated by an operator when machining is started. When the control device 14 detects that the start button 59 has been pressed, the control device 14 first controls the hydraulic control valve 45 so that the rods 24b and 34b are contracted while maintaining the communication state. Then, after the hydraulic control valve 45 is controlled so that the rods 24b and 34b extend, the pneumatic control valve 42 is opened.

  Next, a method for processing the door 100 using the processing apparatus 1 configured as described above will be described. The door 100 is transported in a state where the door body 101 and the sash 102 are integrated, and is placed on the door body anvil 20 and the sash anvil 30 of the processing apparatus 1 as shown in FIG. The placed door 100 is fixed on the anvils 20 and 30 by a fixing device (not shown).

  When the start button 59 is pressed, the control device 14 brings the pneumatic control valve 42 into a communication state. Then, the compressed air sent from the pump 43 flows through the supply and discharge pipes 40 and 41 and flows into the door main body side bag 23 and the sash side bag 33.

  The door main body side bag 23 into which the compressed air has flowed expands between the surface 10b of the bag receiving member 10a and the slide member 22a. When the door main body side bag 23 is inflated, the bag receiving member 10a is fixed to the base 10 and does not move, so that the sliding member 22a is pushed to the left in FIG. When the slide member 22a is pushed, it moves while being guided to the left by the guide rail 22b against the urging force of the spring 22d, whereby the door body punch 21 moves to the left together with the slide member 22a. That is, a through hole (not shown) through which the rod 24b is inserted is formed in the door main body punch 21 and the slide member 22a. The through hole is shaped to allow the door body punch 21 and the slide member 22a to move to the left.

  When the door main body punch 21 moves to the left side, as shown in FIG. 5, the left end of the door main body punch 21 pushes the processed portion 104a of the outer panel 104 to the left side, thereby applying an external force to the processed portion 104a. Bend and bend. The stroke amount of the door main body punch 21 is set so that the door main body punch 21 moves until the left portion of the lower surface of the door main body punch 21 is positioned directly above the workpiece 104a.

  The pressure of the compressed air is set such that the door main body side bag 23 expands to such an extent that the processed portion 104a of the outer panel 104 can be preliminarily bent. Further, the strength of the door main body side bag 23 is set so as to sufficiently withstand this pressure.

  The sash side bag 33 is inflated between the surface 10c of the bag receiving member 10a and the slide member 32a. When the sash side bag 33 is inflated, since the bag receiving member 10a is fixed to the base 10 and does not move, the sliding member 32a is pushed to the upper right in FIG. 1 by the expansion force of the sash side bag 33. When the slide member 32a is pushed, it is guided to the upper right by the guide rail 32b, whereby the sash punch 31 moves together with the slide member 32a. That is, a through hole (not shown) through which the rod 34b is inserted is formed in the sash punch 31 and the slide member 32a. This through hole is shaped to allow the sash punch 31 and the slide member 32a to move to the right.

  When the sash punch 31 is moved obliquely upward to the right, the right end portion of the sash punch 31 pushes the processed portion 110a of the outer member 110 to the right, thereby applying an external force to the processed portion 110a and bending it. The stroke amount of the sash punch 31 is set so that the sash punch 31 moves until the right portion of the lower surface of the sash punch 31 is positioned directly above the workpiece 110a. The above is the preliminary bending process (first bending process) in the hemming process.

  Since the compressed air is supplied to the door main body side bag 23 and the sash side bag 33 substantially simultaneously, the door main body punch 21 and the sash punch 31 move substantially simultaneously, and the processed parts 104a and 110a are preliminarily bent. Is done.

  Thereafter, the control device 14 controls the hydraulic control valve 45 to contract the rods 24 b and 34 b of the door main body side hydraulic cylinder 24 and the sash side hydraulic cylinder 34. As shown in FIG. 6, when the rod 24 b contracts, the engaging portion 24 c engages with the upper surface of the door body punch 21 to move the door body punch 21 downward. Then, the left portion of the lower surface of the door main body punch 21 pushes the processed portion 104 a downward, the processed portion 104 a becomes the final shape, and the belt line reinforcement 105 is sandwiched by the outer panel 104.

  When the rod 34b is contracted, the engaging portion 34c engages with the upper surface of the sash punch 31 and moves the sash punch 31 downward. Then, the right portion of the lower surface of the sash punch 31 pushes the processed portion 110 a downward, the processed portion 110 a becomes the final shape, and the channel member 112 is sandwiched by the outer member 110. The above is the main bending process (second bending process).

  Thereafter, when the control device 14 controls the hydraulic control valve 45 to extend the rods 24b, 34b of the door main body side hydraulic cylinder 24 and the sash side hydraulic cylinder 34, the door main body punch 21 and the sash punch are shown in FIG. 31 is moved upward by the floating springs 22e and 32e.

  Next, when the control device 14 opens the air pressure control valve 42, the door main body side bag 23 and the sash side bag 33 are crushed by the urging force of the springs 22d and 32d as shown in FIG. The air in the bag 23 and the sash side bag 33 is discharged. Therefore, a device for sucking air in the door main body side bag 23 and the sash side bag 33 is unnecessary.

  The floating springs 22e and 32e and the springs 22d and 32d may be gas springs, for example, in addition to the coil springs.

  As described above, according to the processing apparatus 1 and the processing method according to the first embodiment, the punches 21 and 31 are processed using the door main body side bag 23 and the sash side bag 33 capable of supplying and discharging compressed air. Since they are pressed against the parts 104a and 110a, they can be compactly assembled.

  In addition, the pre-bending process is performed using the door main body side bag 23 and the sash side bag 33 before the final shape is obtained. The pre-bending process can be performed with a smaller force than the main bending process, and therefore the load on the door main body side bag 23 and the sash side bag 33 can be reduced. Thereby, the door main body side bag 23 and the sash side bag 33 can be obtained with an inexpensive structure.

  In the first embodiment, the door main body punch 21 is driven by one door main body side bag 23. However, the present invention is not limited to this, and a plurality of door main body side bags 23 may be driven. . In this case, a plurality of door main body side bags 23 may be stacked in the thickness direction, so-called serial arrangement, or a plurality of door main body side bags 23 may be arranged side by side in the width direction. Also good. The stroke amount can be increased by arranging in series, and the burden per bag 23 can be reduced by arranging in parallel. The same applies to the sash punch 31.
