[0013] The further technical improvement of the present invention lies in that: a pressing roller is rotatably provided at one end of the L-shaped turning frame, and a rubber rod is fixedly installed at the middle part of the L-shaped turning frame; in the process of the extended end of the hydraulic cylinder extending to the longest, the composite metal belt is pressed by the anti-skid strip at the bottom of the slider, and the pressing roller rolls on the surface of the composite metal belt, and the L-shaped turning frame is turned over, so that the rubber rod contacts the surface of the composite metal belt, and the lifting plate is controlled to continue to move downward, and the thrust of the two third thrust springs makes the slider cooperate with the anti-skid strip to press and fix the composite metal belt more stably. At the same time, the lifting plate moves downward, causing the L-shaped turning frame to turn over, and the turning movement of the rubber rod is coordinated to The composite metal strip is tightened to prevent wrinkles and unevenness from occurring during the stamping process, which may affect the stamping efficiency and ensure the product quality of the stamped parts. When the extended end of the hydraulic cylinder is extended to its longest position, the L-shaped flip frame flips into the flip groove, providing an upward thrust to the first roller and the lifting rod, so that the piston slides upward to above the input end of the oil injection pipe, and the grinding oil entering the regulating pipe will be sprayed along the oil injection pipe to the parts stamped out of the punching and cutting die, which not only cools down the punching and cutting die, but also flushes the parts stuck in the punching and cutting die down through the impact force of the grinding oil sprayed out of the oil injection pipe, thereby ensuring the efficiency of stamping the composite metal strip.

Through the thrust of the two third thrust springs, the slider cooperates with the anti-skid strip to press and fix the composite metal strip more stably. At the same time, the lifting plate moves downward, so that the L-shaped flip frame flips, and the composite metal strip is tightened in cooperation with the flipping movement of the rubber rod, so as to avoid the composite metal strip from being pressed. During the process, wrinkles and unevenness are likely to occur, which affect the efficiency of stamping and ensure the product quality of the stamped parts; when the extended end of the hydraulic cylinder is extended to the longest, the L-shaped flip frame flips into the flip groove, providing an upward thrust to the first roller and the lifting rod, so that the piston slides upward to above the input end of the injection pipe, and the grinding oil entering the regulating pipe will be sprayed along the injection pipe to the parts stamped out of the punching and cutting die, which not only cools down the punching and cutting die, but also uses the impact force of the grinding oil sprayed out of the injection pipe to flush the parts stuck in the punching and cutting die, thereby ensuring the efficiency of stamping the composite metal strip.

[0019] When the present invention is in use, when the extended end of the hydraulic cylinder is extended to its longest length, the cutting knife moves downward and cooperates with the cutting groove to cut off the excess composite metal strip, and then the extended end of the hydraulic cylinder is controlled to shrink to its shortest length. During this process, the lifting plate moves upward and cooperates with the second roller to provide rotational power to the rotating frame, so that the transmission rod and the third roller move downward, rolling and pressing the excess composite metal strip to completely disconnect it, thereby ensuring the efficiency of recycling and reprocessing the composite metal strip.

In this process, the lifting plate 8 moves upward and cooperates with the second roller 308 to provide rotational power to the rotating frame 309, so that the transmission rod 302 and the third roller 305 move downward, rolling and pressing the excess composite metal strip to make it completely disconnected, thereby ensuring the efficiency of recycling and reprocessing the composite metal strip.
