Figure 8 As shown), the fixed workbench 2 and the right mounting bracket 4 for mounting the positioning block 3, the positioning block 3 is connected to the cylinder 6 through a connecting mechanism 5, and the positioning block 3 is processed with two upper and lower positioning holes 31, and the position of the positioning hole 31 matches the hole 72 (as shown Figure 3 The bracket 4 is fixed to the connecting plate 53 of the connecting mechanism 5 by a push rod 43 (as shown in FIG. Figure 1 As shown), the connecting mechanism 5 includes a connecting plate 53 fixedly connected to the cylinder rod of the cylinder 6, two front flanges 54 are installed in the middle of the connecting plate 53, and a connecting rod 52 is movably connected to the front flange 54. The other end of the connecting rod 52 is a rear flange 51, and the rear flange 51 is fixedly connected to the positioning block 3. The connecting rod 52 is located in the front flange 54 and has a large end 521 processed therein. The large end 521 makes a linear reciprocating motion along the central inner hole of the front flange 54. A positioning rod 9 is fixedly installed in the middle position of the connecting plate 53, and the positioning rod 9 passes through the positioning hole 31 and matches the positioning process hole 22. The bracket 4 includes an integrally formed side plate 41 and a bottom plate 42. The side plate 41 contacts the right side surface of the fixed workbench 2, and the bottom plate 42 contacts the bottom surface of the fixed workbench 2. The bottom plate 42 is fixedly connected to the push rod 43 (as shown in FIG. 1 ). Figure 5 The middle part of the fixed workbench 2 is processed with a cuttings discharge hole 21 from top to bottom, the front side of the fixed workbench 2 is processed with a positioning process hole 22, and the upper right part of the fixed workbench 2 is processed with an inclined surface 23 (as shown in FIG. Figure 5 As shown in FIG. 1 , the cuttings discharge hole 21 is a through hole, the positioning process hole 22 is a deep hole, the position of the positioning process hole 22 matches the hole 72, and the width of the processing bevel 23 is greater than half the width of the bending part 7. A drill bit 8 is installed above the cuttings discharge hole 21.

[0025] The device is connected to the bracket through the cylinder. When the cylinder pushes the positioning block to position the bent part, the bracket moves backward. The bent part loses the support of the bracket and falls from the right side under the action of the inclined surface of the fixed workbench to complete the unloading. When the bent part is processed, the cylinder resets and drives the bracket to move forward. The bottom plate of the bracket blocks the gap between the fixed workbench and the positioning block. The bent part that has been processed is pushed by the flat feeder at the back and reaches the far right side of the fixed workbench. It is supported by the bottom plate. The bent part that has been processed can realize the positioning of the left and right straight lines of the bent part to be processed later. The device is simple and realizes the automated production of punching of bent parts.

[0026] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0027] During operation, the bent plate to be processed is placed on the horizontal conveyor, with the flange (71) facing upward in the same direction as the fixed workbench, the cylinder does not work, there is a gap between the fixed workbench and the positioning block, the thickness of the gap matches the thickness of the long side of the bent plate, the bottom plate of the bracket blocks the gap below the fixed workbench and the positioning block, and there is a certain gap between the large end of the connecting rod and the connecting plate. The horizontal feeder works, pushing the bent part slowly to the right, until the rightmost bent part hits the side plate of the bracket, and the bent part behind the rightmost bent part enters the processing position, the pushing stops, the cylinder works, and the positioning rod is pushed toward the bent part through the connecting plate of the connecting mechanism. Since the front end of the positioning rod is chamfered, the positioning rod is convenient to enter the hole of the bent part at the processing position, and finally enters the positioning process hole to realize the left and right positioning of the bent part. At the same time, the push rod on the connecting plate drives the bracket to retreat, and the gap under the fixed workbench and the positioning block is exposed. The bent part loses the bottom plate support of the bracket. Under the action of the inclined surface of the fixed workbench, the center of gravity tilts toward the inclined surface and falls from the right side (see Figure 7 ), the rightmost bending part is unloaded (during the first operation, the rightmost bending part has no holes and needs to be reprocessed. The rightmost bending part behind is a processed part and does not need to be reprocessed). The cylinder continues to work, the connecting plate contacts the large end of the connecting rod, and finally the bending part is completely fixed. The drill bit moves downward to form the hole to be processed (73). The drill bit moves upward, and the iron chips after drilling fall from the drilling chip unloading hole. The cylinder returns to drive the bracket to move forward. The bottom plate of the bracket blocks the gap between the fixed workbench and the positioning block. The processed bending part is pushed by the flat feeder bending part behind to the rightmost side of the fixed workbench. It is supported by the bottom plate. The processed bending part realizes the positioning of the left and right straight lines of the bending part to be processed behind. Repeat the above actions to realize the automatic punching of the bending part.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
