[0025] In this embodiment, the support frame 2 is an arched structure, and guide rods 7 are fixedly installed at the front and rear ends of the bottom of the support frame 2. The other end of the guide rod 7 is fixedly installed on the base 1. The movable seat 3 is slidably installed on the guide rod 7. A spring 8 is provided between the movable seat 3 and the base 1. The spring 8 is mounted on the guide rod 7. After the stamping is completed, the movable seat 3 bounces upward under the action of the spring 8 to reset.
[0026] In this embodiment, columns 9 are fixedly installed at the four corners of the base 1, a top plate 10 is fixedly installed at the top of the column 9, a hydraulic cylinder 11 is fixedly installed on the top plate 10, the lower pressing plate 5 is fixedly installed at the power output end of the hydraulic cylinder 11, and a polished rod 12 is fixedly installed at the front and rear ends of the top of the lower pressing plate 5. The polished rod 12 is slidably connected to the top plate 10, and a punch 13 is fixedly installed at the bottom of the lower pressing plate 5. The lower pressing plate 5 is driven down by the hydraulic cylinder 11 to perform stamping. Under the action of the punch 13, the parts are bent, and the top front end of the movable seat 3 is in contact with the folding member. The bending plate 4 is hinged, and an extension rod 41 is welded to the rear end of the bending plate 4. The pull rod 6 is fixedly installed on the bottom rear end of the lower pressure plate 5. A makeshift groove 61 is provided on the pull rod 6, and the extension rod 41 is located in the makeshift groove 61. A collection box 14 is fixedly installed on the front side of the base 1. After the stamping is completed, the hydraulic cylinder 11 drives the lower pressure plate 5 to rise to the limit position. At this time, the bending plate 4 is flipped forward under the action of the pull rod 6, so that the bent parts automatically pop out to the front side of the base 1, and the bent parts roll into the collection box 14 for collection after popping out.
[0027] In this embodiment, T-blocks 161 are welded to the front and rear ends of the bottom of the limiting plate 16, and a slide groove 151 corresponding to the T-block 161 is opened on the fixed seat 15.

The staff adjusts the position of the limit plate 16 by adjusting the knob 18 so that the bending part of the part is aligned with the punch 13, so that the bending position of the part can be accurately adjusted, thereby improving the processing accuracy of the part. Then the hydraulic cylinder 11 is started, and the hydraulic cylinder 11 drives the lower pressure plate 5 to descend for stamping. After the stamping is completed, the lower pressure plate 5 rises to the limit position. During the rising process of the lower pressure plate 5, the movable seat 3 is reset upward under the action of the spring 8, and the bending plate 4 is flipped to the front side under the action of the pull rod 6, so that the bent part automatically pops out to the front side of the base 1, and the bent part rolls into the collection box 14 for collection after popping out. Therefore, there is no need for staff to manually take the parts, which improves the convenience of the mold and is conducive to improving production efficiency.
