[0020] Beneficial effects of the present invention:

[0021] (1) During operation, a metal plate to be stamped is placed between a group of L-shaped clamps away from the lower die groove, and the die groove plate is driven by the first motor and the transmission gear ring, so that one of the empty lower die grooves on the die groove plate moves to the bottom of the upper die. At the same time, the second motor rotates 180 degrees to move the metal plate to be stamped to the bottom of the upper die. Then the hydraulic press presses the transmission pressure rod downward, and the metal plate is stamped by the upper die and the lower die groove. After the metal plate is stamped to the bottom of the lower die groove, the upper die reaches the lowest point of the stroke and starts to rise. Then the upper die returns to its initial position, and the metal plate to be stamped is placed again between a group of L-shaped clamps away from the lower die groove. Then the first motor and the second motor are started at the same time to align the upper die with the metal plate to be stamped in the next step and the lower die groove. The upper mold is then punched again, and the above steps are repeated repeatedly. When the hydraulic press presses the transmission pressure rod, the transmission pressure rod drives the first gear sleeve through the first gear rod, drives the transmission cross rod to rotate, and then drives each second gear sleeve to rotate, drives the second gear rod, so that the second gear rod and the first gear rod are in synchronous reverse motion, the second gear rod pushes the connecting block, lifts and lowers the lifting round rod, and then drives the lifting plate, so that the push block and the upper mold move in the opposite direction synchronously. When the upper mold descends, the push block rises, and the sheet metal stamping of the metal plate to be processed and the demoulding and discharging of the processed metal parts are carried out synchronously, and then reset synchronously, thereby reducing the number of power sources, improving the synchronization rate and work efficiency, and the lower mold groove after ejection automatically introduces heat into the air, and uses the length of step rotation to fully dissipate heat, thereby extending the overall working life;

[0022] (2) During operation, the lower die grooves arranged in a circular array on the die groove plate are used to sequentially hold each metal plate, while maintaining the deformation structure of each metal plate after stamping. The time for the die groove plate to rotate at a step angle is used as the shape-keeping time of the metal plate, so that the metal plate can be fully shape-keeping and limited. Then, when the lower die groove containing the metal plate rotates to the top of the push block, the push block is driven by the lifting plate to push and reset in sequence, quickly ejecting the well-shaped metal plate from the lower die groove and avoiding interference with the reciprocating stamping activity of the upper die, thereby ensuring the sheet metal stamping efficiency of the metal plate and the shape-keeping time and effect of the metal plate, so that the sheet metal stamping can be performed well and quickly;

[0023] (3) During operation, the first inclined surface is located above the lower die groove. When the metal plate is deformed and extends into the lower die groove as the upper die is pressed downward, the L-shaped block slides and stretches the first spring through the guidance of the first inclined surface, so that the first spring generates elastic force. Subsequently, when the metal plate is completely pressed into the lower die groove, the metal plate no longer limits the L-shaped block. The elastic force of the first spring is used to reset the L-shaped block and limit the metal plate through the end where the first inclined surface is located, so that the metal plate can fully maintain its shape in the lower die groove and facilitate the separation of the upper die and the metal plate. When the push block moves upward, the support slider first abuts against the transmission ring and pushes the transmission ring upward, thereby causing the transmission push rod to move upward, and the upper end of the transmission push rod abuts against The second inclined surface pushes the L-shaped block laterally through the lateral force component, so that the L-shaped block no longer limits the metal plate, and then the pushing block continues to move upward and abuts against the lower part of the lower die top block, pushing the lower die top block, and then pushing the metal plate to demould, so as to quickly demould the metal part on the other side with the stamping of the upper die, which can not only increase the demoulding speed, but also avoid the lack of sufficient shape retention of the metal plate, and ensure that the upper die can be stamped quickly to maintain the best working efficiency. At the same time, the hydraulic press, transmission pressure rod, upper die, metal plate and lower die groove are coaxial, and the upper die is fixedly connected with the transmission pressure rod without shaking, and the pressure and thrust directions are not skewed, so the stamping quality can be maintained in the best state.

[0043] During operation, each metal plate is sequentially contained in the lower die grooves 108 arranged in a circular array on the die groove plate 103, while maintaining the deformation structure of each metal plate after stamping, and the time for the die groove plate 103 to rotate in a stepping angle is used as the shape-keeping time of the metal plate, so that the metal plate is fully shape-keeping and limited, and then when the lower die groove 108 containing the metal plate rotates to the top of the push block 206, the push block 206 is driven by the lifting plate 205 to push and reset in sequence, quickly ejecting the shape-keeping metal plate from the lower die groove 108 and avoiding interference with the reciprocating stamping activity of the upper die 106, thereby ensuring the sheet metal stamping efficiency of the metal plate and the shape-keeping time and effect of the metal plate, so as to perform sheet metal stamping well and quickly;

[0044] During operation, the first inclined surface 307 is located above the lower die groove 108. When the metal plate is deformed and extends into the lower die groove 108 as the upper die 106 is pressed downward, the L-shaped block 303 is guided by the first inclined surface 307 to slide and stretch the first spring 306, so that the first spring 306 generates elastic force. Subsequently, when the metal plate is completely pressed into the lower die groove 108, the metal plate no longer limits the L-shaped block 303. The elastic force of the first spring 306 is used to reset the L-shaped block 303 and limit the metal plate at the end where the first inclined surface 307 is located, so that the metal plate is fully kept in shape in the lower die groove 108, and the upper die 106 is conveniently separated from the metal plate. When the push block 206 moves upward, the support slider 311 first abuts against the transmission ring 309 and pushes the transmission ring 309 to move upward, thereby causing the transmission push rod 310 to move upward. The upper end of the push rod 310 abuts the second inclined surface 308, and pushes the L-shaped block 303 laterally through the lateral component force, so that the L-shaped block 303 no longer limits the metal plate, and then the push block 206 continues to move upward and abuts against the lower part of the lower mold top block 301, pushing the lower mold top block 301, and then pushing the metal plate to demould, so that the metal part on the other side can be demoulded quickly with the stamping of the upper mold 106, which can not only increase the demoulding speed, but also avoid the lack of sufficient shape retention of the metal plate, and ensure that the upper mold 106 can be stamped quickly to maintain the best working efficiency. At the same time, the hydraulic press 104, the transmission pressure rod 105, the upper mold 106, the metal plate and the lower mold groove 108 are coaxial, and the upper mold 106 is fixedly connected with the transmission pressure rod 105, will not shake, and the pressure and thrust directions will not be skewed, so the stamping quality can be maintained in the best state.
