All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] Reference Figure 1-3, a punching die for processing a car seat frame, comprising a support box 1, two punching dies 3, two L-shaped plates 2 and a placement seat 13, the placement seat 13 is fixedly installed at the top center position of the support box 1, and two strip openings 11 are provided on the top of the support box 1, and the two L-shaped plates 2 are respectively slidably installed in the corresponding strip openings 11, and tooth plates 21 are slidably installed on the top inner wall and the bottom inner wall of the support box 1, and the same gear 22 is rotatably installed on the front and rear inner walls of the support box 1, and the two tooth plates 21 are meshed with the gear 22, and the ends of the two tooth plates 21 away from each other are fixedly connected to the corresponding L-shaped plates 2, so that when the gear 22 rotates, the two L-shaped plates 2 can control the corresponding punching dies 3 to move in opposite directions, and the two punching dies 3 are respectively fixedly installed on the side where the two L-shaped plates 2 are close to each other, and a strip opening 2 12 is provided on the bottom inner wall of the support box 1, and the strip opening 2 12 slides inside. A slider 24 is installed, and the slider 24 is fixedly connected to the tooth plate 21 below. An electric cylinder 23 is fixedly installed on the bottom of the support box 1, and the working end of the electric cylinder 23 is fixedly connected to the slider 24, which can control the tooth plate 21 below to adjust the lateral position. A U-shaped plate 41 is slidably installed on the two L-shaped plates 2, and a plurality of springs 42 are fixedly installed on the side of the U-shaped plate 41 close to the punching die 3. The ends of the plurality of springs 42 away from the U-shaped plate 41 are fixedly installed on the punching die 3. A limit frame 4 is fixedly installed on the side where the two U-shaped plates 41 are close to each other. The two limit frames 4 are respectively adapted to the corresponding punching dies 3, and can control the two punching dies 3 to move in the direction of approaching each other and perform the punching operation of the car seat frame. The limit frame 4 can clamp and limit the car seat frame before the punching die 3, thereby ensuring the stability of the car seat frame when the punching die 3 performs the punching operation.

[0024] In this embodiment, a support block is fixedly installed at the bottom of the support box 1, and the electric cylinder 23 is horizontally fixedly installed on the support block, which can provide stable support for the electric cylinder 23.

[0025] In this embodiment, a guide rod 43 is slidably installed on the U-shaped plate 41, and the guide rod 43 is fixedly connected to the punching die 3. A limiting block is fixedly installed on the end of the guide rod 43 away from the punching die 3, which can provide guidance for the U-shaped plate 41 and prevent the U-shaped plate 41 from slipping off the guide rod 43.

[0026] In this embodiment, the material of the placement seat 13 is rubber, and the top side of the placement seat 13 is provided with anti-slip grooves, which can prevent sliding when the car seat frame is clamped and limited by the rectangular frame and then punched.

[0027] The circuits, electronic components and modules involved all use existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.

[0028] Working principle: When in use, first turn on the power and place the car seat frame that needs to be punched in the center position on the placement seat 13, then control the slider 24 through the electric cylinder 23 to drive the lower tooth plate 21 to slide to the left, and under the action of the gear 22, the upper tooth plate 21 can slide to the right, so that the two L-shaped plates 2 can drive the corresponding punching dies 3 to move towards each other. In this process, the rectangular frame first contacts the car seat frame and under the action of multiple springs 42, the rectangular frame provides a clamping limit for the car seat frame, and the anti-slip texture arranged on the top side of the placement seat 13 is provided. Closing it can prevent the car seat frame from sliding. As the two punching dies 3 continue to approach each other, the punching operation of the car seat frame can be realized. After the punching is completed, the electric cylinder 23 is controlled to retract, which can make the two punching dies 3 move away from each other, so that the punched car seat frame can be quickly separated from the punching die 3 with the cooperation of the rectangular frame, U-shaped plate 41 and multiple springs 42. Then, after the two rectangular frames are out of contact with the car seat frame, the car seat frame is removed and another car seat frame to be punched is placed and the punching operation can be continued in the above manner.

[0029] The above describes in detail the punching die for manufacturing automobile seat frames provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
