There is a fixed column 10, and a cutting blade 12 is installed at the bottom of the fixed column 10. A moving groove 11 is opened on the fixed column 10, and a top plate 15 is movably inserted through the moving groove 11. A push rod 13 is installed at the bottom of the top plate 15, and the push rod 13 movably inserts through the bottom of the fixed column 10 and the top of the cutting blade 12. A spring 14 is connected between the bottom of the top plate 15 and the bottom of the inner wall of the moving groove 11. A pressure plate 16 is set above the top plate 15 and is installed on the inner wall of the upper cutting mold 9. A fixed plate 17 is installed on the inner wall of the upper cutting mold 9. A connecting plate 18 is installed on the outer wall of the fixed column 10, and a spring 20 is connected between the bottom of the connecting plate 18 and the top of the fixed plate 17.
[0024] Furthermore, spring 14 surrounds the outer wall of top rod 13, top plate 15 is adapted to moving groove 11, and pressure pad 21 is installed at the bottom of cutting upper mold 9.
[0025] The pressure pad 21 provides a certain buffering effect and protection for the gasket.
[0026] Furthermore, a limiting rod 19 is installed at the top of the fixed plate 17, the limiting rod 19 moves through the connecting plate 18, and the second spring 20 surrounds the outer wall of the limiting rod 19.
[0027] The limiting rod 19 can limit the position of the fixed plate 17 and the second spring 20, ensuring the stability of the fixed plate 17 and the second spring 20 during compression.
[0028] Furthermore, a positioning component for positioning washers is provided inside the placement groove 6. The positioning component includes a positioning block 23 and a screw 25. A sliding groove 22 is provided at the bottom of the inner wall of the placement groove 6. The positioning block 23 is slidably connected to the sliding groove 22. One end of the screw 25 is rotatably connected to the inner wall of the sliding groove 22 through a bearing seat. The other end of the screw 25 moves through the sliding groove 22. The screw 25 is rotatably connected to the supporting lower mold 5 through a bearing. The positioning block 23 is threaded onto the outer wall of the screw 25. A knob 26 is installed at one end of the screw 25.
[0029] Furthermore, there are three positioning blocks 23 and three sliding grooves 22, and the positioning blocks 23 and the sliding grooves 22 are compatible.
[0030] The positioning block 23 facilitates the positioning of the gasket in the placement groove 6, thereby improving the stability of the gasket in the placement groove 6.
[0031] Furthermore, a scale plate 24 is installed on the outside of the positioning block 23. The scale plate 24 moves through the inner wall of the placement groove 6. A pointer 27 is set above the scale plate 24 and is installed on the inner wall of the placement groove 6.
[0032] The scale plate 24 and pointer 27 are designed to make it easier for personnel to adjust the position of the positioning block 23 in the placement slot 6 more accurately, thus ensuring the accuracy of the gasket positioning.
[0033] The operating principle of a fastening washer forming mold is as follows: The washer to be cut and formed is placed in the placement groove 6. Then, according to the washer specifications, the knob 26 is rotated, causing the screw 25 to rotate. The screw 25 then moves the positioning blocks 23 towards the washer, ultimately bringing the positioning blocks 23 into contact with the washer. The positioning blocks 23 then push the washer towards the center of the placement groove 6, thus positioning the washer within the placement groove 6 using the three positioning blocks 23. At this point, the hydraulic cylinder 4 is activated, driving the fixing column... 10 moves downwards, and the fixed column 10, through the connecting plate 18, spring 20, and fixed plate 17, drives the upper cutting mold 9 to move downwards, ultimately pressing the washer in the placement groove 6 with the upper cutting mold 9. Meanwhile, the hydraulic cylinder 4 continues to drive the fixed column 10 to move downwards, and the fixed column 10 drives the connecting plate 18 to compress the spring 20. Finally, the fixed column 10 drives the cutting blade 12 to contact the washer, so that the cutting blade 12 punches the center hole of the washer. Then, the hydraulic cylinder 4 is activated to retract, causing the hydraulic cylinder 4 to drive the fixed column 10 to move upwards. The fixed column 10 moves the top plate 15 upward via spring 14. At this time, spring 20 is still compressed. The upper cutting mold 9 remains stationary, and the top plate 15 contacts the pressure plate 16. The pressure plate 16 presses the top plate 15 downward, causing the top plate 15 to compress spring 14. This causes the top plate 15 to move the ejector rod 13 downward, allowing the ejector rod 13 to push out any gasket material that may be attached to the cutting blade 12, allowing the gasket material to fall normally into the cutting groove 7. Through the above structure, the ejector rod 13 can be used to... After the cutting blade 12 has finished cutting, any gasket material that may be attached to it will be ejected and fall normally into the cutting groove 7. This prevents the gasket material from adhering to the cutting blade 12 and affecting the subsequent normal punching operation of the cutting blade 12. This solves the problem in the existing technical solution that after the cutting blade cuts the gasket, the cut gasket material is easy to adhere to the cutting blade and is difficult to fall off normally, which affects the subsequent normal punching operation of the cutting blade and requires manual cleaning, thus affecting the punching efficiency of the gasket and posing certain safety hazards.
