A sink groove is provided on the workbench 61, and the lower surface of the sink groove is in the same plane as the upper surface of the die 64. The ejector block 632 is slidably connected to the sink groove of the workbench 61, and the upper surface of the ejector block 632 is lower than the lower surface of the guide groove of the workbench 61.

[0034] When the pressing block 71 is raised or lowered, the connecting block 72 is used to control the movement of the pushing block 631. The ejection spring 634 can eject the pushing block 631 to prevent the pushing block 631 from being unable to slide due to unbalanced force. The ejection block 632 ejects the product, and the stopper 633 prevents the pushing block 631 from sliding out of the guide groove of the mounting block 67.

[0035] like Figure 1-Figure 11 As shown, the forming process of the energy storage battery heat sink specifically includes the following steps: S1. Turn the rotating handle 57 to drive the driving bevel gear 55 to rotate, and then drive the transmission assembly 54 to operate, which can simultaneously control the lifting and lowering of the threaded column 62, and adjust the workbench 61 to a suitable height: the driving bevel gear 55 controls the rotation of the driven bevel gear 544 through the double-headed bevel gear 545, and the threaded tube 541 follows the rotation of the driven bevel gear 544 to control the lifting and lowering of the threaded column 62; S2. Place the metal coil on the unwinding rack 1, and the metal coil enters the box 21. The top conveying roller 25 and the bottom conveying roller 26 are driven by the conveying motor 29 to rotate and transport the metal coil. The metal coil is guided by the bottom guide roller 22 and the top guide roller 23 to automatically adjust the height and flatten the metal coil. The two ends of the metal coil are kept horizontal on the guide block 24: the guide block 24 only contacts the edge of the metal coil to prevent the metal coil from being scratched. S3, the flattened metal coil is transported to the workbench 61, the flywheel assembly 9 is driven to drive the eccentric crank 81 to rotate, the crank shaft 82 moves with the eccentric crank 81, the slider 83 is controlled to rise and fall on the guide rail 84, the pressing block 71 follows the slider 83 to rise and fall, and the cutting blade 73 and the punch 74 are controlled to punch the metal coil: the cutting blade 73 separates the product from the metal coil, and the punch 74 cooperates with the die 64 to press out the shape of the product; S4. The stamped product is pushed out of the workbench 61 through the ejection assembly 63: when the pressing block 71 rises, the thrust of the pushing block 631 from the connecting block 72 is converted into a pulling force, and the ejection block 632 is controlled to eject the stamped product in cooperation with the ejection spring 634.

[0036] The working principle of the present invention is as follows: rotating the rotating handle 57 drives the driving bevel gear 55 to rotate, thereby driving the transmission component 54 to operate, and can simultaneously control the lifting and lowering of the threaded column 62, adjust the workbench 61 to a suitable height, place the metal coil on the unwinding rack 1, and the metal coil enters the box body 21. The top conveying roller 25 and the bottom conveying roller 26 are driven by the conveying motor 29 to rotate and transport the metal coil. The metal coil is guided by the bottom guide roller 22 and the top guide roller 23 to automatically adjust the height and flatten. The two ends of the metal coil are kept horizontal on the guide block 24. The flattened metal coil is transported to the workbench 61, and the flywheel group 9 is driven to drive the eccentric crank 81 to rotate. The crank shaft 82 moves with the eccentric crank 81, and the slider 83 is controlled to lift and lower on the guide rail 84. The pressing block 71 follows the slider 83 to lift and lower, and the cutting blade 73 and the punch 74 are controlled to stamp the metal coil. The stamped product is pushed out of the workbench 61 through the ejection component 63.
