[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by providing the bottom plate, the stamping telescopic device, the support column, the base, the lower mold body, the connecting shell, the upper mold body and the elastic buffer device, the connecting shell and the upper mold body can be driven to move downward under the action of the stamping telescopic device until both the upper mold body and the lower mold body are in contact with the sheet metal part, thereby realizing the stamping of the sheet metal part. After that, as the stamping telescopic device pushes the connecting shell and the upper mold body to move, the connecting shell and the lower mold body together punch and shear the waste generated by the stamping of the outer side of the sheet metal part after stamping, thereby reducing the number of stamping times of automobile sheet metal parts processing and improving the efficiency of the production line; 2. In the present invention, by providing the placement plate, vertical slot, rotating slot, positioning slot, push rod, slider, slide rod, second spring, cutting rod, first tooth plate, cutting knife body, second tooth plate and gear, the push rod can be brought into contact with the sheet metal part in advance when the connecting shell moves downward to punch and shear the periphery of the sheet metal part. At this time, the sheet metal part can be driven by the first tooth plate to rotate the gear, and the gear drives the cutting rod and the cutting knife body to move downward through the second tooth plate, and the waste material on the periphery of the sheet metal part is cut by the cutting knife body to prevent the waste material of the annular sheet metal part from being left outside the lower mold body and unable to be taken out in time. When the connecting shell moves upward, the second spring pushes the slide rod to move outside the slide rod. At this time, the slide rod drives the push rod to move downward, and the gear rotates in the opposite direction, driving the cutting rod and the cutting knife body to move upward, realizing the resetting of the cutting knife body. At the same time, the placement plate can be conveniently positioned and installed by providing the mounting plate, the second bolt and the connecting block. 3. In the present invention, by providing the supporting plate, the first fixed plate, the first supporting plate, the rotating shaft, the limiting column, the first spring, the rotating wheel, the rubber sleeve, the sponge plate, the groove and the placement groove, after the punching and shearing of the outer side of the sheet metal part is completed, the first supporting plate can be pushed upward under the action of the first spring, and the first fixed plate, the rotating shaft, the rotating wheel and the rubber sleeve can be driven to move upward through the first supporting plate. After the top of the sheet metal waste leaves the connecting shell, one side of the sheet metal part tilts. At this time, the sheet metal part moves outside the rubber sleeve, driving the rubber sleeve and the rotating wheel to rotate, which is convenient for guiding the sheet metal waste, so that the sheet metal waste falls off quickly and prevents the sheet metal waste from accumulating on the lower mold body. At the same time, when the connecting shell and the lower mold body punch and shear the waste around the sheet metal part, the sheet metal part can be buffered under the action of the rubber sleeve and the sponge plate, reducing the impact between the rotating wheel and the rotating shaft and the rotating shaft and the first fixed plate, so that the rotating wheel and the rotating shaft can rotate more stably; 4. In the present invention, the first bolt can be directly removed by the cover plate, the fixing block, the limiting plate, the handle, the first bolt, the slide groove, the top plate, the limiting groove and the connecting plate, and then the buffer body can be pulled outward by the handle. The buffer body is installed in the top plate through the fixing block and the limiting plate. At the same time, the buffer body is connected to the upper mold body arranged below through the slide groove and the connecting plate. When one of the buffer bodies is removed, it can be connected through other buffer bodies to prevent the upper mold body from falling downward when maintaining the buffer body, and the buffer body can be quickly and conveniently taken out for maintenance; 5. In the present invention, by providing a fixed block, a limiting plate, a top plate, a limiting groove, an installation groove, a second fixed plate, a second supporting plate, a limiting wheel, a fixed frame, a limiting frame and a spring sheet, the fixed block can be limited by the limiting wheel during the process of taking out the buffer body, so as to remind the staff that the buffer body is about to be taken out. At this time, the staff can hold the bottom of the buffer body and then continue to move the buffer body. At this time, the buffer body drives the fixed block and the limiting plate to move forward, and the limiting wheel rotates on the second fixed plate. At the same time, the limiting wheel pushes the second fixed plate and the second supporting plate to move, so that the spring sheet is compressed by force. Before the fixed block leaves the two limiting wheels After that, by lifting the buffer body, the buffer body is prevented from falling rapidly under the action of its own gravity when it is suddenly taken out, reminding the staff to respond to the removal of the buffer body in time to prevent the buffer body from falling and being damaged. After the buffer body is taken out, the limiting wheel can be moved downward, and the limiting wheel drives the second supporting plate to move downward through the second fixed plate. At this time, the spring leaf pushes the spring leaf to deform under the action of the arc-shaped inner wall of the installation groove. Maintenance can be carried out after the limiting wheel is taken out. After the maintenance is completed, the limiting wheel, the second fixed plate and the second supporting plate are installed back into the installation groove opened by the top plate. At this time, the arc-shaped position of the spring leaf and the arc-shaped inner wall of the installation groove are engaged with each other to position the limiting wheel.
