[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 The first embodiment of this utility model provides a limiting structure for a stamping and forming device for a thin steel plate locker, including a support base 1, a support frame 2, a stamping mechanism 3 and a mold 4. The lower surface of the support frame 2 is fixedly connected to the upper surface of the support base 1, the stamping mechanism 3 is fixedly connected to the upper surface of the support frame 2, the lower surface of the mold 4 is fixedly connected to the upper surface of the support base 1, and a limiting mechanism 5 is provided on the outer surface of the mold 4. There are four limiting mechanisms 5. The four limiting mechanisms 5 include anti-slip plate 51, limiting plate 52, spring 53 and sliding component 54. The anti-slip plate 51 is in contact with the outer surface of the mold 4 on one side. The limiting plate 52 is fixedly connected to the opposite side of the anti-slip plate 51 on one side. The spring 53 is fixedly connected to the opposite side of the limiting plate 52 on one side. The sliding component 54 is provided on the lower surface of the limiting plate 52. The sliding assembly 54 includes a sliding block 541 and a sliding groove 542. The upper surface of the sliding block 541 is fixedly connected to the lower surface of the limiting plate 52. The sliding groove 542 is opened on the upper surface of the support base 1. The inner wall of the sliding groove 542 is slidably connected to the outer surface of the sliding block 541. The inner wall of the sliding groove 542 is fixedly connected to the opposite end of the spring 53.

[0022] Specifically, the sliding block 541 drives the limiting plate 52 and the anti-slip plate 51 to move in tandem, so as to achieve precise centering of the steel plate on the mold 4. The design of the anti-slip plate 51 closely fitting the surface of the steel plate can effectively resist the stamping impact, prevent the steel plate from shifting, ensure stamping accuracy, and significantly reduce the scrap rate.

[0023] Furthermore, the steel plate is placed on the upper surface of the mold 4. According to the length of the steel plate, the sliding block 541 moves inward along the inner wall of the sliding groove 542. At the same time, the spring 53 pushes the sliding block 541, and the sliding block 541 drives the limiting plate 52, so that the limiting plate 52 drives the anti-slip plate 51 to approach the outer surface of the steel plate until the anti-slip plate 51 is tightly attached to the outer surface of the steel plate, fixing the steel plate. Then, the steel plate is stamped by the stamping mechanism 3.

[0024] Example 2 In the second embodiment of this utility model, a push-pull assembly 6 is provided on the lower surface of the sliding block 541. Four push-pull assemblies 6 are provided. The four push-pull assemblies 6 include a first fixing member 61, a push-pull plate 62, and a second fixing member 63. The upper surface of the first fixing member 61 is fixedly connected to the lower surface of the sliding block 541. The upper end of the push-pull plate 62 is rotatably connected to the inner wall of the first fixing member 61 through a rotating shaft. The inner wall of the second fixing member 63 is rotatably connected to the lower end of the push-pull plate 62 through a rotating shaft. A support plate 7 is provided on the lower surface of the second fastener 63, and the upper surface of the support plate 7 is fixedly connected to the lower surface of the second fastener 63.

[0025] Specifically, through the multi-stage transmission of the support plate 7, the second fixing member 63, the push-pull plate 62, the first fixing member 61 and the sliding block 541, the vertical driving force is converted into the horizontal clamping force.

[0026] Furthermore, by moving the support plate 7 downwards, the support plate 7 can pull the second fixing member 63, which in turn pulls the push-pull plate 62, causing the push-pull plate 62 to pull the first fixing member 61. The first fixing member 61 then drives the sliding block 541 to move closer to the steel plate along the inner wall of the sliding groove 542.

[0027] Example 3 In the third embodiment of this utility model, a telescopic component 8 is provided on the lower surface of the support plate 7. The telescopic component 8 includes a support column 81 and a fixed column 82. The upper end face of the support column 81 is fixedly connected to the lower surface of the support plate 7, and the lower surface of the fixed column 82 is fixedly connected to the inner wall of the support base 1. The inner wall of the fixed column 82 and the outer surface of the support column 81 are slidably connected. A transmission assembly 9 is provided on the outer surface of the support column 81. The transmission assembly 9 includes a toothed plate 91, a gear 92, a groove 93, a connecting rod 94, and a servo motor 95. The left surface of the toothed plate 91 is fixedly connected to the outer surface of the support column 81. The outer surface of the gear 92 and the right surface of the toothed plate 91 are in a meshing relationship. The groove 93 is opened on the outer surface of the fixed column 82. The front end of the connecting rod 94 is fixedly connected to the rear surface of the gear 92. The output end of the servo motor 95 is fixedly connected to the rear end of the connecting rod 94. The rear surface of the servo motor 95 is fixedly connected to the inner wall of the support base 1. A third fixing member 10 is provided on the outer surface of the connecting rod 94. The inner wall of the third fixing member 10 is rotatably connected to the outer surface of the connecting rod 94 via a rotating shaft. The lower surface of the third fixing member 10 is fixedly connected to the inner wall of the support base 1.

[0028] Specifically, the servo motor 95 can adjust its speed and torque in real time, the gear 92 and toothed plate 91 can withstand large loads, and the choice of materials such as alloy steel or stainless steel further improves wear resistance and lifespan, and enhances the stability of equipment operation.

[0029] Furthermore, the servo motor 95 drives the connecting rod 94 to rotate, the connecting rod 94 drives the gear 92 to rotate, the gear 92 rotates and meshes with the gear plate 91, so that the gear plate 91 drives the support column 81 to move downward, and the support column 81 drives the support plate 7 to move downward together.

[0030] Working principle: The servo motor 95 drives the connecting rod 94 to rotate, which in turn drives the gear 92 to rotate. The gear 92 meshes with the gear plate 91, causing the gear plate 91 to move the support column 81 upward. The support column 81 then moves the support plate 7 upward together. The support plate 7 can pull the second fixing member 63, which in turn pulls the push-pull plate 62. This causes the push-pull plate 62 to pull the first fixing member 61, which in turn causes the sliding block 541 to move outward along the inner wall of the sliding groove 542. The sliding block 541 compresses the spring 53, causing the spring 53 to generate elastic force. At this time, the sliding block 541 can drive the limiting plate 52, and the limiting plate 52 drives the anti-slip plate 51 to move outward together. At this time, the steel plate is placed on the upper surface of the mold 4. Then, the servo motor 95 is rotated in the opposite direction, which indirectly causes the sliding block 541 to move inward along the inner wall of the sliding groove 542. At the same time, the spring 53 releases its elastic force to push the sliding block 541. The sliding block 541 drives the limiting plate 52, which causes the limiting plate 52 to drive the anti-slip plate 51 to move closer to the outer surface of the steel plate until the anti-slip plate 51 is tightly attached to the outer surface of the steel plate, fixing the steel plate. Finally, the steel plate is stamped by the stamping mechanism 3.

[0031] In summary, the combination of the limiting mechanism 5, the push-pull assembly 6, the support plate 7, the telescopic assembly 8, the transmission assembly 9, and the third fixing component 10 solves the problem that the lack of limiting treatment for the square storage plate in the device leads to the displacement of the holes and grooves after stamping, which affects the accuracy of subsequent assembly and makes it impossible for the plate to fit seamlessly with other components.
