[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to materials by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts.

[0003] At present, during the use of existing stamping and forming dies, the push rod and the stamping head are fixedly connected. When the parts to be stamped require different stamping heads for stamping or the stamping head is damaged, it is not convenient to disassemble and replace the stamping head. And usually after stamping, it needs to be taken out manually. However, usually the parts are pressed tightly in the stamping die and are relatively difficult to take out. It is time-consuming and laborious for the staff to perform demoulding, and there are certain deficiencies. In view of this, a stamping device for the production of automobile seat parts is proposed to solve the above problems. Summary of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model

[0026] Please refer to Figure 1-2 , a stamping device for the production of automobile seat parts in this embodiment, including a base 1, a bracket 2 fixed on the base 1, a cylinder 3 fixed on the bracket 2, a mold groove 4 fixed at the output end of the cylinder 3, a stamping die body 5 arranged at the lower end of the mold groove 4, a mounting mechanism 8 arranged on the mold groove 4, an ejecting mechanism 7 arranged on the base 1, and a lower die 6 fixed on the base 1

[0027] The mounting mechanism 8 includes a first cavity 801, a fixed block 807, a handle 812 and a second cavity 806. A first cavity 801 is opened in the mold groove 4. A horizontally arranged rotatable threaded rod 802 is arranged in the first cavity 801. A slider 803 that can move relatively or away from each other is threadedly connected to the threaded rod 802. A limiting rod 804 is fixed on one side of the slider 803

[0028] A fixed block 807 is fixed at the upper end of the stamping die body 5. The fixed block 807 is slidably connected to the second cavity 806. Limiting grooves for engaging with the limiting rod 804 are opened on both sides of the fixed block 807

[0029] By rotating the threaded rod 802, the threaded rod 802 drives the two sliders 803 to move away from each other, thereby synchronously driving the limiting rod 804. Subsequently, the limiting rod 804 moves outside the limiting groove, and then the stamping die body 5 on the fixed block 807 is disassembled and then replaced.

[0030] Among them, the two ends of the threaded rod 802 have opposite threads. One end of the threaded rod 802 penetrates through the first cavity 801 and extends outside the die groove 4. One side of the slider 803 is slidably connected to the inner side of the first cavity 801, so that the threaded rod 802 can drive the two sliders 803 to move relatively or away from each other to adjust the distance between the two limiting rods 804.

[0031] At the same time, a ratchet wheel is fixed in the middle of the threaded rod 802. A liftable lifting plate 809 is arranged in the first cavity 801. A ratchet pawl 810 is arranged on the lifting frame. The ratchet pawl 810 is stuck on the ratchet wheel 805. A first spring 808 is arranged between the lifting plate 809 and the inner bottom of the first cavity 801.

[0032] A handle 812 is arranged outside the die groove 4. The handle 812 is connected to the lifting frame through a sliding rod 811. The sliding rod 811 is slidably arranged on the die groove 4 along its axis. During the rotation of the threaded rod 802, it is unidirectionally locked by the cooperation of the ratchet pawl 810 and the ratchet wheel 805, thereby effectively preventing the threaded rod 802 from rotating in the reverse direction due to vibration and accidental rotation. Avoid the situation that after the limiting rod 804 is stuck in the limiting groove and makes a reverse movement to open, so that the stamping die body 5 cannot fall off.

[0033] Please refer to the figure. The ejection mechanism 7 in this embodiment includes a third cavity 701. An air pump 702 and a piston cylinder 705 are sequentially fixed in the third cavity 701. The air outlet end of the air pump 702 is communicated with the piston cylinder 705 through an air delivery pipe 704. A piston plate 706 is closely slidably arranged in the piston cylinder 705. A piston rod 707 is fixed on the piston plate 706. One end of the piston rod 707 is fixed with an ejection plate 708. A placement groove 709 that is closely slidably matched with the ejection plate 708 is opened at the inner bottom of the lower die 6. A second spring 710 is sleeved on the piston rod 707

[0034] By starting the air pump 702, the air pump 702 delivers gas to the air delivery pipe 704 and flows into the piston cylinder 705. Then, the gas pushes the piston plate 706 to rise, and the piston rod 707 and the ejection plate 708 rise synchronously. Subsequently, the ejection plate 708 pulls the second spring 710, and then the stamped parts are ejected through the ejection plate 708.

[0035] Among them, both ends of the second spring 710 are respectively fixed to the ejector plate 708 and the upper end of the piston cylinder 705. Through the arrangement of the second spring 710, after the ejector plate 708 ejects the components, the ejector plate 708 can automatically retract into the placement groove 709.

[0036] At the same time, an air discharge pipe 703 is connected to the air delivery pipe 704, and an air release valve is fixed on the air discharge pipe 703, which is convenient for discharging the gas in the piston cylinder 705.

[0037] The working principle of the above embodiment is as follows:

[0038] When using this stamping die to stamp components, place the components on the lower die 6, and then start the cylinder 3 to drive the die groove 4 and the stamping die body 5 to move downward, and the stamping of the components can be achieved.

[0039] After the stamping of the components is completed, start the air pump 702. The air pump 702 delivers gas to the air delivery pipe 704, flows into the piston cylinder 705, and then the piston plate 706 is pushed up by the gas. The piston rod 707 and the ejector plate 708 rise synchronously. Subsequently, the ejector plate 708 pulls the second spring 710, and then the stamped components are ejected by the ejector plate 708. Then, by opening the air release valve, the gas in the piston cylinder 705 is discharged, and then the ejector plate 708 is driven by the resilience of the second spring 710 to retract into the placement groove 709.

[0040] When it is necessary to replace the stamping die body 5, press down the handle 812, so that the slide bar 811 drives the pawl 810 on the lifting plate 809 away from the ratchet wheel, and then rotate the threaded rod 802 to drive the two sliders 803 to move away from each other, thereby synchronously driving the limit rod 804. Subsequently, the limit rod 804 moves out of the limit groove, and then the stamping die body 5 on the fixed block 807 is disassembled.

[0041] When it is necessary to install the stamping die body 5, rotate the threaded rod 802 in the reverse direction. The threaded rod 802 drives the limit rod 804 on the two sliders 803 to snap into the limit groove to install the stamping die body 5.

[0042] To prevent the threaded rod 802 from rotating, the threaded rod 802 is unidirectionally locked by the cooperation of the pawl 810 and the ratchet wheel 805, thereby effectively preventing the threaded rod 802 from rotating in the reverse direction due to vibration and accidental rotation. Avoid the situation that after the limit rod 804 snaps into the limit groove, it moves in the opposite direction and opens, so that the stamping die body 5 cannot fall off.
