[0037] In order to make the purposes, technical schemes and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0038] Example 1

[0039] Please refer to Figures 1-5 The embodiment is a punching die of automobile plate parts, which comprises:

[0040] The main body assembly comprises a placing block 11, a lower die 12 fixed on the lower surface of the placing block 11, a sliding groove 13 opened in the front side wall of the lower die 12, and an upper die 14 suspendedly connected above the lower die 12;

[0041] The upper die 14 is suspendedly connected above the lower die 12 and can move up and down. The upper die 14 is another part of the stamping tool and is used to cooperate with the lower die 12 to realize the stamping operation on the plate by applying a stamping force to the plate. The upper die 14 has a proper shape and protrusions or recesses to cooperate with the recesses or protrusions on the lower die 12 to realize the punching or forming process.

[0042] The alignment assembly comprises a placing groove 21 opened in the inner center of the upper end of the lower die 12, a movable groove 22 opened in the middle of the lower surface of the placing block 11, a motor 23 fixedly installed in the inner part of the placing groove 21, a gear 24 fixedly connected to the output end of the motor 23, a first rack 25 engaged with the rear side of the gear 24, a first limiting frame 251 fixed on the right side of the lower surface of the movable groove 22, a first side plate 26 fixed on the right side wall of the first rack 25, and a first connecting plate 261 connected to the upper surface of the first side plate 26.

[0043] The movable groove 22 is in the middle of the lower surface of the placing block 11 and is part of the alignment assembly, allowing the horizontal movement of the rack to control the rack. The motor 23 is fixedly installed in the inner part of the placing groove 21 and its output end is connected to the gear 24. The motor 23 is responsible for providing power to drive the gear 24 to rotate. The first rack 25 is located on the rear side of the gear 24 and is engaged with the gear 24. Its function is to receive the rotary motion of the gear 24 and convert it into linear motion.

[0044] The alignment assembly further comprises a second rack 27 engaged with the front side of the gear 24, a second limiting frame 271 fixed on the left side of the lower surface of the movable groove 22, a second side plate 28 fixedly connected to the left side wall of the second rack 27, and a second connecting plate 281 connected to the upper surface of the second side plate 28.

[0045] The second rack 27 is engaged with the front side of the gear 24 and is opposite to the first rack 25 in the movable groove 22. Its function is similar to that of the first rack 25, which is used to convert the rotary motion of the gear 24 into linear motion. The second limiting frame 271 is fixed on the left side of the lower surface of the movable groove 22 and is used in cooperation with the second rack 27. Its function is to limit the movement range of the second rack 27 to ensure the stability of the alignment.

[0046] Working principle:

[0047] When punching the automobile plate;

[0048] First, the worker places the automobile plate on the upper surface of the placing block 11, and then the worker starts the motor 23 through the external control module,

[0049] At this time, the motor 23 is turned on to drive the gear 24 to rotate,

[0050] When the gear 24 rotates clockwise, under the limiting of the first limiting frame 251 and the second limiting frame 271, the first rack 25 moves to the right, and the second rack 27 moves to the left. This movement process can adjust the two sides of the first connecting plate 261 and the second connecting plate 281 to the appropriate position, control the motor 23 to reverse, at this time the gear 24 rotates counterclockwise, this operation will drive the first side plate 26 and the second side plate 28 to move to the middle through the reverse movement of the first rack 25 and the second rack 27,

[0051] When the first connecting plate 261 and the second connecting plate 281 move to the middle, in this process, the first connecting plate 261 and the second connecting plate 281 will clamp the automobile plate part to ensure its alignment

[0052] This step ensures the accurate alignment between the automobile plate part and the stamping die, so that the position and shape of the punching are more accurate and consistent. This can improve the precision of punching and ensure that it meets the design requirements and meets the needs of parts assembly.
