A right die assembly is mounted on one end of the upper surface of the mounting base via three supports. The right die assembly has a scrap ejector. The upper surface of the mounting base has two sliding rails, each with a sliding seat connected to it. A left die assembly is fixed between the upper ends of the two sliding seats. The left die assembly has a workpiece ejector that ejects the internal workpiece. A support plate is located at the left end of the mounting base. The support plate has three stamping cylinders that drive the left die assembly and sliding seats to slide along the sliding rails. The support plate also has two pushers that actuate the workpiece ejector. This design not only allows for faster workpiece processing and the processing of multiple workpieces at a time, but also facilitates demolding and collection of workpieces, and allows for the collection and export of small scrap pieces, making it more convenient to use.

The geared motor 303 is an RV series worm gear geared motor, which has a built-in self-locking function of worm gear transmission.

[0030] In this embodiment, the metal plate 4 is automatically conveyed by the roller driven by the geared motor 303, reducing manual intervention; the detection roller 304, together with the angle encoder 305, monitors the feeding distance in real time, and the data is transmitted to the control panel 5 to ensure that the metal plate 4 is accurately placed; it can be linked with the punching rhythm to realize continuous feeding and effectively improve the overall processing efficiency.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] Working principle: The metal plate 4 to be processed is inserted between the feeding roller 301 and the base 1, so that the metal plate 4 passes through the surface of the base 1 and passes through the corresponding areas of the lower stamping cutter 212 and the upper stamping cutter 210. At the same time, it is ensured that the upper surface of the metal plate 4 is in close contact with the outer surface of the detection roller 304. The first hydraulic telescopic rod 201 is activated, and its output end drives the moving frame 207 to move through the connecting rod 217. This causes the moving frame 207, which was originally between the lower stamping cutter 212 and the upper stamping cutter 210, to move out of the punching area as a whole, avoiding interference between the frame and the cutter during the punching process and making room for punching the metal plate 4. The second hydraulic telescopic rod 203 is activated, and its output end pushes the lower pressure plate 214 to move downward. The lower pressure plate 214 simultaneously drives the upper stamping cutter 210 at the bottom to move closer to the lower stamping cutter 212 embedded in the base 1. The upper stamping cutter 210 and the lower stamping cutter 212 cooperate precisely to punch the metal plate 4 between them. During the punching process, the metal plate 4 is cut into finished connecting pieces that meet the specifications, and the finished products are temporarily attached to the upper punching cutter 210; the waste generated by punching falls naturally through the through hole on the lower punching cutter 212 and finally falls into the waste collection bin 216 below for collection. After the punching is completed, the second hydraulic telescopic rod 203 is activated again, which drives the lower pressure plate 214 and the upper punching cutter 210 to reset upward; then the first hydraulic telescopic rod 201 is activated, driving the moving frame 207 to move back between the lower punching cutter 212 and the upper punching cutter 210. Next, the lower pressure plate 214 continues to move upward, causing the push rod 209 to slide along the inner wall of the upper punching cutter 210 and extend into the cutter, pushing the adhered connecting piece out of the cutter. The pushed-out piece falls onto the outer surface of the roller 208 of the moving frame 207, and with the help of the inclined structure of the roller 208, slides down the inclined surface into the preset finished product collection bin 211, completing the finished product collection. After a single punching and finished product collection is completed, the reduction motor 303 is started, and its output shaft drives the feeding roller 301 to rotate. The feeding roller 301 drives the metal plate 4 to continue moving towards the punching area through friction. During this process, the detection roller 304 rotates synchronously with the metal plate 4, monitoring the moving distance of the metal plate 4 in real time. When the metal plate 4 is detected to have moved to the preset position required for the next punching, the reduction motor 303 stops driving, the metal plate 4 is positioned and ready, and the above punching process can be repeated, realizing continuous automatic feeding and cyclic punching of the metal plate 4, improving the overall processing efficiency.
