[0026] The utility model provides an anti-scratch punching device. Figures 1 to 2 This is a specific embodiment of the anti-scratch punching device provided by the utility model.

[0027] Reference Figures 1 to 2 The anti-scratch stamping device includes: a fixing mechanism 1, including a forming block 11 and a pressing block 12, a sheet 4 is fixed between the forming block 11 and the pressing block 12, and the sheet 4 has a structure to be stamped 41 extending out of the forming block 11 along a first direction; a stamping mechanism, including a forming punch 21 provided on one side of the pressing block 12 in the first direction, and the position of the forming punch 21 corresponds to the structure to be stamped 41; a driving mechanism, driving and connecting the forming punch 21, used to drive the forming punch 21 to move toward the structure to be stamped 41 to bend the structure to be stamped 41; a roller 3, provided at one end of the forming punch 21 close to the structure to be stamped 41, and the roller 3 extends along a second direction, and the first direction is perpendicular to the second direction.

[0028] In this embodiment, the pressing piece is used to clamp and fix the material sheet 4 with the forming block 11, and the driving mechanism is used to drive the forming punch 21 to move toward the structure to be punched 41, thereby bending the structure to be punched 41. In the process of the forming punch 21 bending the material sheet 4, the roller 3 can roll on the surface of the material strip, thereby avoiding the problem of the forming punch 21 directly rubbing against the material sheet 4, causing the material sheet 4 to be scratched by the forming punch 21.

[0029] To facilitate the following description, Figure 1 In the example shown, the first direction is the left-right direction, the second direction is the front-back direction, and the forming punch 21 is used to move downward to bend the sheet 4. Specifically, the number of the fixing mechanisms 1 and the punching mechanisms is set to two, the two fixing mechanisms 1 fixing the sheet 4 are arranged symmetrically on the left and right, and the two punching mechanisms are arranged symmetrically on the left and right. The structures to be punched 41 at the left and right ends of the sheet 4 extend out of the two fixing mechanisms 1 respectively, and the two punching mechanisms are used to bend the two structures to be punched 41 respectively.

[0030] Furthermore, the driving mechanism is connected to the pressing block 12, and the driving mechanism is used to drive the pressing block 12 to move toward the forming block 11 to fix the sheet 4. In this embodiment, the driving mechanism drives the pressing block 12 downward to press the sheet 4 onto the upper surface of the forming block 11. During this process, the driving mechanism stably and continuously provides pressure to the pressing block 12 to press the sheet 4 downward, thereby firmly fixing the sheet 4 and ensuring that the material does not move during the stamping process, thereby improving the stamping accuracy. This downward pressing and fixing method can also be used to fix strips of different thicknesses, which is more practical. Specifically, the driving mechanism is configured as a punch press.

[0031] Furthermore, an elastic block 13 is provided at one end of the pressing block 12 near the structure to be punched 41. In this embodiment, the flexibility of the elastic block 13 makes the pressure distribution of the pressing block 12 on the sheet 4 more uniform, so that the pressing block 12 provides a more stable fixing effect, thereby improving the punching quality; at the moment when the pressing block 12 contacts the sheet 4, the elastic block 13 can absorb the impact force of the pressing block 12, reducing the direct impact on the structure to be punched 41 and preventing the pressing block 12 from deforming.

[0032] Furthermore, the elastic block 13 is made of polytetrafluoroethylene. In this embodiment, polytetrafluoroethylene has good elasticity, allowing it to tightly adhere to the sheet 4 during the pressing process, improving the fixing effect. It can also effectively absorb and cushion the impact force during the stamping process, protecting the sheet 4. In addition, polytetrafluoroethylene is not easy to age, and can maintain stable elasticity during long-term use, reducing replacement frequency and maintenance costs.

[0033] Furthermore, the elastic block 13 is provided with a mounting hole, and the pressure block 12 is provided with a screw hole corresponding to the position of the mounting hole, and the mounting hole and the screw hole are connected by screws. In this embodiment, the screw connection method can ensure that the elastic block 13 and the pressure block 12 are firmly connected, reducing loosening caused by vibration or impact during operation. The screw connection method is also simple to install and disassemble, making the elastic block 13 more convenient to maintain.

[0034] Furthermore, the forming block 11 has an inclined surface 14 on one side thereof, which is close to the structure to be punched 41. The inclined surface 14 is inclined along a first direction toward the structure to be punched 41. In this embodiment, the design of the inclined surface 14 allows the sheet 4 to deform slightly after being fixed, making it easier to shape during the punching process and avoiding the problem of the sheet 4 being broken by excessive punching force from the forming punch 21.

[0035] Furthermore, the inclined surface 14 is configured as an electrical discharge machined surface. In this embodiment, the inclined surface 14 is subjected to electrical discharge machining to make the inclined surface 14 very smooth, without burrs or ridges, thereby preventing the tablet 4 from being scratched. This ensures that the tablet 4 fits tightly against the inclined surface 14, thereby improving the fixing stability of the forming block 11 on the tablet 4.

[0036] The present invention also proposes a stamping device, which includes an anti-scratch stamping device. The specific structure of the anti-scratch stamping device refers to the above-mentioned embodiment. Since the stamping device proposed by the present invention includes all schemes of all embodiments of the above-mentioned anti-scratch stamping device, it has at least the same technical effect as the anti-scratch stamping device, which will not be elaborated here one by one.

[0037] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
