Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] like Figures 1 to 6 As shown, this application provides a terminal material punching device that ensures stable operation and punching accuracy during the punching process, avoiding problems such as dimensional deviations and excessive burrs during terminal material punching. The terminal material punching device includes a bracket 1, with a first mounting plate 2 mounted on one side of the bracket 1. A support column 6 is mounted on the side of the first mounting plate 2 opposite to the bracket 1, and the support columns 6 are distributed around the first mounting plate 2. A second mounting plate 5 is mounted on the side of the support columns 6 opposite to the first mounting plate 2. A drive mechanism 4 is mounted on the second mounting plate 5, with a first connecting plate 7 connected to the power output end of the drive mechanism 4. A second connecting plate 8 is connected to the end of the first connecting plate 7 opposite to the drive mechanism 4. A guide rail 15 is also mounted on the first mounting plate 2, with the end of the guide rail 15 opposite to the first mounting plate 2 slidably connected to the second mounting plate 8. The second connecting plate 8 can reciprocate along the guide rail 15 under the drive of the drive mechanism 4.

[0035] In some embodiments, a first groove 71 is provided on the side of the first connecting plate 7 near the second connecting plate 8, and a second groove 81 and a hole 82 are provided in the second connecting plate 8. The punching device also includes an elastic body 9, a cold knife 10, and a positioning pin 12. The elastic body 9 is installed in the first groove 71 and the second groove 81. One end of the elastic body 9 is connected to the first connecting plate 7, and the end opposite to the first connecting plate 7 is connected to a mounting block 13. The end of the mounting block 13 opposite to the elastic body 9 is connected to the positioning pin 12. The mounting block 13 passes through the hole 82. The cold knife 10 passes through the hole 82. The cold knife 10 has a T-shaped structure. One end of the cold knife 10 is installed in the second groove 81 and fixedly connected to the second connecting plate 8. The end of the cold knife 10 opposite to the second connecting plate 8 is an inverted "V" shape, with the pointed corner made into a sharp blade, which facilitates rapid punching when the cold knife 10 punches downwards, reduces friction and heat generation during the punching process, and thus ensures the original properties and precision of the material.

[0036] In some embodiments, the positioning pins 12 are conical, and two positioning pins 12 are mounted on each mounting block 13. There are two mounting blocks 13, located on both sides of the cold knife 10. The cold knife 10 has protrusions 101 on both sides near the mounting blocks 13, and a third groove 131 is provided on one side of the mounting block 13. The protrusions 101 and the third groove 131 cooperate to allow relative sliding between the cold knife 10 and the mounting block 13. Two fixed blades 11 are mounted on the first mounting plate 2, located below and corresponding to the mounting blocks 13. The terminal material 16 is a strip structure placed above the fixed blades 11, and one end of the terminal material 16 has multiple small holes. During the punching process, the drive mechanism 4 drives the first connecting plate 7 and the second connecting plate 8 to move downwards along the guide rail 15, causing the positioning pin 12 and the cold knife 10 to move downwards. When the positioning pin 12 passes through the hole on the terminal material 16 and abuts against the fixed knife 11, the cold knife 10 continues to move downwards, punching the terminal material 16. The mounting plate 13 moves upwards along the protrusion 101, compressing the elastic body 9. After punching is completed, the drive mechanism 4 drives the cold knife 10 to move upwards, and the positioning pin 12 and the mounting block 13 return to their initial positions under the action of the elastic body 9. Positioning the terminal material 16 by the positioning pin 12 ensures the stability and accuracy of the equipment cutting, avoids problems such as punching size deviation and excessive burrs on the terminal material 16, and improves product quality.

[0037] In some embodiments, the punching device further includes a receiving frame 14 and a cover 3. The receiving frame 14 is placed on the support 1, located below the first mounting plate 2, to facilitate the collection of the cut terminal material. The cover 3 is mounted on the first mounting plate 2 to prevent the cut terminal material 16 from splashing around and to protect the safety of the workers.

[0038] Optionally, the drive mechanism 4 is a cylinder, which drives the cold knife to move downward by pushing the first connecting plate 7 and the second connecting plate 8 to achieve punching of the terminal material.

[0039] Optionally, the elastic body 9 is a spring, which can deform under the action of external force and return to its initial state after the external force disappears, and occupies a small space.

[0040] Optionally, the cold knife 10 should be made of a metal material with high hardness and high wear resistance. When used in conjunction with the cylinder, it can quickly punch and cut the terminal material, reduce the heat generated by friction during the punching process, and avoid affecting the original properties of the material.

[0041] The working principle of this utility model is as follows: The terminal material 16 can move on the first mounting plate 2. When it moves to the fixed blade 11, it will pause briefly. The drive mechanism 4 of the punching device drives the first connecting plate 7 and the second connecting plate 8 to move downward along the guide rail 15. The positioning pin 12 passes through the terminal material 16 and abuts against the fixed blade 11. The second connecting plate 8 continues to drive the cold blade 10 to punch the terminal material 16 downward. The positioning pin 12 and the mounting plate 13 remain stationary and compress the elastic body 9. After the cold blade 10 has finished punching, the drive mechanism 4 drives the first connecting plate 7 and the second connecting plate 8 to move upward. The positioning pin 12 no longer abuts against the fixed blade 11, and the elasticity of the elastic body 9 is restored, so that the mounting plate 13 and the positioning pin 12 return to their original state, completing the punching of the terminal material 16. The positioning pin 12 can position the terminal material 16, ensuring the stability and accuracy of the cutting equipment, avoiding problems such as punching size deviation and excessive burrs in the terminal material 16, and improving product quality. By combining a cylinder with a cold blade, the punching speed of the cold blade can be accelerated, and the heat generated by friction during the punching process can be reduced, thus avoiding damage to the original properties of the material. This terminal material punching device has a compact structure, is relatively small in size, is easy to operate, and has high punching efficiency. It can not only be used for punching terminal materials, but also for cutting other materials, such as metals, plastics, and paper, making it suitable for a variety of scenarios.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
