Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and particularly to a metal part stamping equipment and a stamping die. Background Art

[0002] Stamping equipment is an important equipment for metal processing. By applying pressure, plastic deformation occurs to the metal material, so as to obtain parts with the required shape and size. A common stamping equipment is a stamping die. The stamping die can process metal materials into parts or semi-finished products. Due to the characteristic of one-time stamping forming of the stamping die, it has become one of the more common stamping equipments.

[0003] During the use of traditional stamping equipment, the main demoulding means is to eject the formed part from the female die through air pressure or a mechanical ejector rod. However, during the demoulding process by means of air pressure or a mechanical ejector rod, it is easy to cause damage and wear to the stamping part.

[0031] The working principle of the above embodiment is as follows: Before using the device, fix the electric telescopic rod 9 to other main body structures to ensure the pushing effect of the electric telescopic rod 9. The fixing method of the electric telescopic rod 9 to other main body structures is a mature existing fixing method, and this application will not elaborate too much on the existing mature technologies and fixing methods; When using the device, place the stamping material on the two semi-body concave dies 6. Before stamping the material, the two semi-body concave dies 6 are in a relatively tightly clamped state, which can ensure close fitting with the punch 3 and guarantee the processing quality of the stamped parts. During the processing, the punch 3 moves downward. During the movement of the punch 3, the vertical tooth plate 10 will move downward. Due to the S-shaped inner wall of the moving groove plate 701, when the vertical tooth plate 10 moves downward, it will drive the gear 710 to rotate counterclockwise in the front view direction of the device. In this way, the gear 710 will drive the longitudinal rod 705 to have a tendency to move counterclockwise through the fixing ring 709. In this way, the longitudinal rod 705 will squeeze the lower inner wall of the moving groove plate 701 through the rotating wheel 708 on the crank block 707, and then the left and right moving groove plates 701 will move relative to each other. In this way, the semi-body concave dies 6 fixed on the moving groove plate 701 will be squeezed more tightly and firmly. However, due to the continuous descent of the vertical tooth plate 10, the two semi-body concave dies 6 are in close contact but will not produce displacement. At this time, the downward extrusion force will be greater than the clamping force of the damping spring 712 in the fixing ring 709 squeezing the limit ball 714 and the circular card slot 713. As a result, the gear 710 will be disengaged from the fixing ring 709. In this way, it will not only not affect the normal processing of the stamped parts, but also not affect the normal meshing transmission of the vertical tooth plate 10 and the gear 710; After stamping is completed, the punch 3 will drive the above structure to run in the reverse direction under the upward drive of the electric telescopic rod 9. At this time, the vertical rod 705 rotates clockwise in the front view direction of the device. In this way, the rotating wheel 708 on the crank block 707 presses against the upper inner wall of the moving groove plate 701, and then the left and right moving groove plates 701 move in the opposite direction. In this way, the semi-body concave die 6 moves in the opposite direction, which will make the stamped part fall better. And during the process of the semi-body concave die 6 moving in the opposite direction, the storage cylinder 802 will move together with the semi-body concave die 6. In this way, the position of the L-shaped push rod 801 remains unchanged, and the storage cylinder 802 moves closer to the L-shaped push rod 801. Under the thrust of the piston block 803, the gas in the storage cylinder 802 will be pushed into the L-shaped cavity 804 and exported through the air outlet 805. This can ensure that the stamped part is separated better, and during the blowing process, the dust and impurities in the semi-body concave die 6 can be cleaned. When the punch 3 rises to a certain height, the vertical tooth plate 10 disengages from the gear 710. At this time, the semi-body concave die 6 will move relatively under the push of the push spring 12. And at this time, the storage cylinder 802 starts to inhale under the movement of the piston block 803 moving away, ensuring the blowing and cleaning effect on the lower side. The second check valve 808 on the storage cylinder 802 can only inhale and not exhale, while the first check valve 807 in the communication port 806 can only exhale and not inhale, which can ensure the separation of the inhalation and exhalation of the storage cylinder 802. After the stamped part is processed, the operator needs to take it out and then place the processing material to prepare for the next processing of the stamped part.

[0032] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components that appear in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle will not be elaborated too much in this embodiment. ​
