A press frame 25 is inserted at the top of the oil groove 24, and a plurality of oil holes are provided at the center of the press frame 25. The top of the oil hole is connected to the oil groove 24. A bottom ring 26 is provided inside the oil groove 24, and the bottom of the bottom ring 26 is connected to the inner bottom surface of the oil groove 24 by an elastic member 27. A ring edge is provided at the top of the press frame 25, and the bottom surface of the press ring 22 corresponds to the ring edge of the press frame 25. When the bottom end of the downwardly moved pressing ring 22 contacts the side of the pressing frame 25, the pressing ring 22 continues to move downward, and the downwardly moved pressing ring 22 uses the ring edge to make the pressing frame 25 move downward inside the oil groove 24, and the downwardly moved pressing frame 25 uses the bottom ring 26 to squeeze the elastic member 27. The lubricating oil inside the oil groove 24 moves upward inside the pressing frame 25 through the oil hole under the action of pressure until the lubricating oil enters the pressing ring 22 through the oil hole; when the pressing ring 22 moves upward, the elastic force of the elastic member 27 makes the top surface of the side of the pressing frame 25 fit with the bottom surface of the pressing ring 22 until the elastic force of the elastic member 27 disappears, and the pressing ring 22 continues to move upward. At this time, the lubricating oil gradually disperses on the top surface of the pressing frame 25 under the action of gravity, and the dispersed lubricating oil gradually enters the inside of the sleeve 16, and the lubricating oil inside the pressing ring 22 moves downward on the surface of the ring bevel 23 until the lubricating oil drips into the inside of the sleeve 16.

When the sleeve 16 moves up and down on the surface of the guide pillar 5, the sleeve 16 moves up and down on the surface of the connecting rod 28 using the side groove 18. At this time, the lubricating oil inside the side groove 18 gradually adheres to the surface of the connecting rod 28 during the up and down movement, and multiple connecting rods 28 provide a smooth up and down sliding effect for the sleeve 16.

[0023] When the lubricating oil moves downward on the surface of the connecting rod 28 and the surface of the guide pillar 5, the lubricating oil gradually moves toward the inner side of the outer ring 29. After the downward-moving sleeve 16 enters the inner side of the outer ring 29, the sleeve 16 cooperates to squeeze the lubricating oil on the inner side of the outer ring 29. The lubricating oil enters the side groove 18 through the gap between the connecting rod 28 and the bottom surface of the sleeve 16, which facilitates the lubricating oil to move up and down between the sleeve 16 and the outer ring 29, thereby ensuring the sliding effect of the sleeve 16 on the surface of the guide pillar 5.

The screw cooperation of the nut 14 and the vertical rod 13 makes the bottom surface of the lower template 2 cooperate to squeeze the top surface of the buffer gasket 15, thereby completing the limitation of the lower template 2.

[0025] Place the workpiece to be processed on the top surface of the press frame 9, start the power device, and the output end of the power device uses the pressing plate 4 to make the upper template 1 move vertically downward. The upper template 1 that moves downward gradually approaches the lower template 2, and the upper template 1 drives the pressing head 8 to move downward synchronously until the bottom surface of the pressing head 8 fits the top surface of the workpiece. The power device uses the pressing plate 4 to make the upper template 1 continue to move downward, and the upper template 1 that moves downward uses the pressing head 8 to press the workpiece into the press frame 9. At this time, the pressing head 8 cooperates with the press frame 9 to stamp the workpiece, and the movable plate 10 that moves downward cooperates with the first spring 12 on the surface of the insertion rod 11. At this time, the insertion rod 11 that moves downward gradually enters the slot of the lower template 2 until the workpiece is stamped and formed inside the press frame 9. The power device uses the pressure plate 4 to pull the upper template 1 upward, and the elastic force of the first spring 12 makes the top surface of the workpiece of the movable plate 10 fit with the bottom surface of the pressing head 8. The elastic force of the first spring 12 makes the formed workpiece move up synchronously with the pressing head 8 until the top surface of the movable plate 10 fits with the top surface of the pressing frame 9, and the pressing head 8 continues to move up. At this time, the bottom surface of the pressing head 8 is separated from the workpiece, and the elastic force of the first spring 12 pushes the processed power supply casing out of the inside of the pressing frame 9, making it convenient to remove the power supply casing, and then the new workpiece to be processed is placed on the top of the pressing frame 9, and the new workpiece is continued to be stamped through the cooperation of the pressing head 8 and the pressing frame 9.

The upper template 1 moves downward with the top ring 7 to drive the sleeve 16 to move downward on the surface of the guide pillar 5. The sleeve 16 moves downward with the second spring 19 that squeezes the surface of the guide pillar 5. The top ring 7 moves downward to drive the pressure ring 22 synchronously downward, and the sleeve 16 moves downward on the surface of the guide pillar 5 to provide a guide for the downward movement of the upper template 1. direction, causing the upper template 1 to move vertically downward; when the upper template 1 moves upward, the elastic force of the second spring 19 causes the sleeve 16 to move up on the surface of the guide pillar 5, and the upward moving sleeve 16 causes the limiting rod 21 to always be inserted into the bottom groove of the top ring 7 until the elastic force of the second spring 19 disappears, and the upper template 1 that continues to move upward uses the top ring 7 to move up on the surface of the limiting rod 21, and the multiple limiting rods 21 at the top of the sleeve 16 continue to provide vertical guidance with the upward movement of the upper template 1, so that the upper template 1 can move vertically up and down.

[0027] When the bottom end of the downwardly moved pressing ring 22 contacts the side of the pressing frame 25, the pressing ring 22 continues to move downward, and the downwardly moved pressing ring 22 uses the ring edge to make the pressing frame 25 move downward inside the oil groove 24, and the downwardly moved pressing frame 25 uses the bottom ring 26 to squeeze the elastic member 27. The lubricating oil inside the oil groove 24 moves upward inside the pressing frame 25 through the oil hole under the action of pressure until the lubricating oil enters the pressing ring 22 through the oil hole; when the pressing ring 22 moves upward, the elastic force of the elastic member 27 makes the top surface of the side of the pressing frame 25 fit with the bottom surface of the pressing ring 22 until the elastic force of the elastic member 27 disappears, and the pressing ring 22 continues to move upward. At this time, the lubricating oil gradually disperses on the top surface of the pressing frame 25 under the action of gravity, and the dispersed lubricating oil gradually enters the inside of the sleeve 16, and the lubricating oil inside the pressing ring 22 moves downward on the surface of the ring bevel 23 until the lubricating oil drips into the inside of the sleeve 16. The lubricating oil diffuses through the top surface of the guide pillar 5 until it enters the inside of the side groove 18, and the lubricating oil moves downward inside the side groove 18 through the gap between the side plate 17 and the side groove 18. The side groove 18 is lubricated by the lubricating oil, and the lubricating oil inside the side groove 18 will adhere to the surface of the guide pillar 5, so that the side plate 17 can move up and down smoothly inside the side groove 18. Through lubrication, the up and down movement of the sleeve 16 and the guide pillar 5 can avoid excessive friction loss.
