[0003] Stamping equipment is an indispensable tool for stamping processing. The stamping equipment in the prior art all adopts an eccentric shaft module to directly connect the stamping spindle, that is, the eccentric shaft module directly drives the stamping spindle to move up and down and back and forth, thereby achieving the purpose of improving the stamping power.

[0004] However, since the eccentric shaft module directly drives the stamping spindle to move up and down and back and forth, without any shock-absorbing structure or reverse thrust structure, the stamping equipment makes loud noises during operation and is easily damaged, thus affecting the stamping quality. Moreover, when the eccentric shaft module directly drives the stamping spindle to move upward, a large force is required, that is, the motor load used to drive the eccentric shaft module is large, which is labor-intensive and power-consuming, causing great trouble to users.

[0005] In view of this, the inventor proposes the following technical solution. Summary of the invention:

[0008] Furthermore, in the above technical solution, a fork portion in the shape of a semi-square frame is formed at the rear end of the shock-absorbing reverse thrust arm, and the fork portion is sleeved on the outer periphery of the upper end of the stamping spindle and is hinged by a hinge.

When the present invention is working, when the stamping spindle 2 moves downward, the shock-absorbing reverse thrust arm 51 swings downward with the pivot groove 531 as the fulcrum, that is, the end point of the shock-absorbing reverse thrust arm 51 hinged to the stamping spindle 2 swings downward. At this time, the spring 52 will be compressed. The reaction force generated during the compression of the spring 52 has a buffering and shock-absorbing effect on the stamping spindle 2 when it moves downward, which can reduce the vibration of the machine without generating a large noise, and can protect the stamping spindle to a certain extent and ensure the stamping quality of the stamping spindle; subsequently, when the stamping spindle 2 is reset and moves upward, the spring 52 is released from the compressed state and generates an upward reaction force, which pushes the stamping spindle 2 to assist the stamping spindle 2 to move upward, thereby reducing the motor load and achieving the purpose of saving labor and electricity, making the present invention highly competitive in the market.

[0024] The rear end of the shock-absorbing reverse thrust arm 51 is formed with a fork portion 511 in a semi-square frame shape. The fork portion 511 is sleeved on the outer periphery of the upper end of the stamping spindle 2 and is hinged by a hinge 54, and its assembly structure is stable.

[0025] The hinge 54 is provided with a second oil passage 541 for the flow of lubricating oil at the periphery thereof, and the second oil passage 541 includes a second annular oil groove 501 provided at the periphery of the hinge 54, a third annular oil groove 502 provided at the end of the hinge 54, and a second connecting hole 503 formed inside the hinge 54 and connecting the second annular oil groove 501 and the third annular oil groove 502. The hinge 54 is provided with the second oil passage 541 for the flow of lubricating oil, which is used to ensure the smoothness of the hinge, thereby saving the use of conventional oil pipes, that is, reducing parts, and avoiding the cumbersome installation and maintenance of the oil pipes.

[0026] A strip oil storage groove 532 is arranged at the bottom of the pivot groove 531 in the pivot seat 53, and a third connecting hole 533 penetrating the bottom surface of the pivot seat 53 is also arranged at the bottom of the strip oil storage groove 532, so as to ensure that the pivot groove 531 and the pivot 12 are smoothly connected at all times, thereby saving the use of conventional oil pipes, reducing parts and components, and avoiding the tedious installation and maintenance of the oil pipes.

[0027] An oil plate 55 is installed between the upper end surface of the front end of the shock-absorbing reverse thrust arm 51 and the pivot seat 53, and the upper end surface of the oil plate 55 is provided with a plurality of interconnected first oil storage grooves 551, and the side of the oil plate 55 is provided with oil filling holes 552. The oil plate 55 is also provided with a first connecting hole 553 that passes through the first oil storage groove 551 and the oil filling holes 552; the lower end surface of the pivot seat 53 covers the upper end of the first oil storage groove 551, so that the first oil storage groove 551 is connected to the third connecting hole 533.

[0028] A groove 512 is provided in the middle of the lower end of the shock-absorbing reverse thrust arm 51, and the upper end of the spring 52 is placed in the groove 512, so as to ensure the stability of the assembly structure.

[0029] To sum up, when the present invention is working, when the stamping spindle 2 moves downward, the shock-absorbing reverse thrust arm 51 swings downward with the pivot groove 531 as the fulcrum, that is, the end point of the shock-absorbing reverse thrust arm 51 hinged to the stamping spindle 2 swings downward, and at this time, the spring 52 will be compressed. The reaction force generated during the compression of the spring 52 has a buffering and shock-absorbing effect on the downward stamping movement of the stamping spindle 2, which can reduce the vibration of the machine without generating a large noise, and can protect the stamping spindle to a certain extent and ensure the stamping quality of the stamping spindle; subsequently, when the stamping spindle 2 is reset and moves upward, the spring 52 is released from the compressed state and generates an upward reaction force, and the reaction force pushes the stamping spindle 2 to assist the stamping spindle 2 to move upward, thereby reducing the motor load and achieving the purpose of saving labor and electricity, making the present invention highly competitive in the market.
