[0002] The car sunroof guide rail is a key component in the sunroof system. It is responsible for guiding the movement of the sunroof glass and ensuring the smooth opening, closing and positioning of the sunroof.

[0003] Currently, the punching device used in the car sunroof guide rail can usually only punch one hole at a time, which also tests the experience of the processing personnel. The low processing efficiency will also lead to a high rate of defective products. Although there are some devices that can complete the punching in one go, they are more dependent on molds. For car sunroof guide rails of different specifications, the mold needs to be significantly changed, which brings inconvenience to production and leads to a significant increase in production costs.

[0025] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0026] As mentioned above, the present invention provides a punching device for a sunroof guide rail of an automobile, which includes a frame 1, a stamping assembly and a clamping assembly, wherein the stamping assembly includes a stamping part 2 and a stamping plate 21, wherein the stamping part 2 is arranged above the frame 1, and the stamping plate 21 is arranged at the stamping end of the stamping part 2, and the bottom of the stamping plate 21 is provided with a slide groove 22 extending along the length direction of the stamping plate 21, and a plurality of stamping blocks 23 are provided on the slide groove 22; and the clamping assembly includes a clamping base plate 31, wherein the clamping base plate 31 is arranged at the bottom of the frame 1, and a groove 32 is provided on the clamping base plate 31, and the groove 32 is provided with positive and negative grooves perpendicular to the length direction of the groove 32. The screw rod 4 has two clamping blocks 5 arranged opposite to each other on the forward and reverse screw rods 4 for clamping the automobile sunroof guide rail 6. Through the above technical solution, with the cooperation of the frame 1, the stamping assembly and the clamping assembly, the forward and reverse screw rods 4 are arranged on the clamping base plate 31, and the grooves 32 are set to limit the clamping blocks 5, so that the automobile sunroof guide rail 6 can be clamped stably in the device. Through the coordinated use of the stamping part 2, the stamping plate 21, the slide groove 22 and the stamping block 23, the automobile sunroof guide rail 6 of this model can be punched multiple times continuously after one adjustment, which effectively improves the production efficiency. The device can also change the distance between the stamping blocks 23 and replace the stamping blocks 23 to cope with the situation where production needs to be changed, thereby greatly reducing production costs.

[0027] like Figure 1-2 As shown, the frame 1, which serves as the support structure for the entire stamping device, is designed as a two-layer structure, including a top plate 11 and a support plate 12. The top plate 11 and the support plate 12 are securely connected by a number of support rods 13, forming a sturdy frame structure to ensure stability and precision during the stamping process. The support rods 13 are fixed to the top plate 11 and the support plate 12 by welding, bolting, or integral molding, and are sufficient to withstand the huge loads generated during the stamping process.

[0028] In some embodiments, the stamping element 2 is hydraulically driven. The stamping element 2 is mounted on the top plate 11 of the frame 1. The stamping element 2 drives the punch block 23 to reciprocate vertically, exerting a strong punching force on the workpiece placed on the punch plate 21, thereby achieving the stamping process. Hydraulic transmission offers the advantages of high power, smooth operation, and precise control of punching speed and pressure, thereby improving processing quality and efficiency.

[0029] According to the technical solution provided by the present invention, the punch block 23 is the executive component of the punch part 2, which moves downward under the action of hydraulic pressure to transfer force to the workpiece. In order to facilitate the installation and replacement of the stamping die or the punch head 234, preferably, a fixing assembly is provided on the punch block 23. The fixing assembly enables the punch head 234 to be quickly and firmly connected to the punch block 23. Specifically, the fixing assembly includes an auxiliary plate 231 and a screw 232. The auxiliary plate 231 is preferably fixedly connected to the bottom of the punch block 23 in advance. A plurality of threaded holes 233 that are adapted to the size of the screw 232 are provided on the auxiliary plate 231. When the punch head 234 needs to be installed or replaced, the corresponding punch head 234 can be screwed into the threaded hole 233 of the auxiliary plate 231 through the screw 232 to achieve rapid positioning and tightening. This design greatly improves the mold changing efficiency and versatility of the equipment.

[0030] In some embodiments, a detachable punch head 234 is provided at the bottom of the punch block 23. The detachable punch head 234 is connected to the punch block 23 via the aforementioned fixing assembly. Punching heads 234 of different shapes can be quickly replaced to suit the specific punching requirements of the sunroof guide rail 6. This detachable design not only enhances the flexibility and applicability of the device but also reduces equipment maintenance costs and tool replacement time.

[0031] According to the technical solution provided by the present invention, the bottom surface of the stamping plate 21 is coated with a wear-resistant coating. The stamping plate 21 needs to withstand repeated tightening and extrusion of the screw 232 on the auxiliary plate 231. Therefore, coating the stamping plate 21 with a wear-resistant coating can effectively reduce the friction and wear between the stamping plate 21 and the workpiece or mold during long-term use, extend the service life of the stamping plate 21, and help maintain the dimensional accuracy of the stamped part 2. For example, tungsten carbide, titanium nitride, aluminum oxide, or a polymer-based composite material with high hardness and low friction coefficient can be used.

[0032] like Figure 3As shown, the central portion of the forward and reverse screw rods 4 is directly opposite the vertical movement axis of the punching block 23, which means that its point of action is aligned with the punching axis of the punching block 23, ensuring the accuracy of force transmission and position adjustment and avoiding eccentric loading. The forward and reverse screw rods 4 can be rotated manually or by motor drive to achieve vertical lifting or clamping force of the connected parts thereon. It is worth noting that the motor drive here is a common driving means for the forward and reverse screw rods 4, so it will not be described in detail.

[0033] According to the technical solution provided by the present invention, a support block 41 is provided at the center of the groove 32, and the support block 41 is also provided with a hole for the forward and reverse spiral screw rods 4 to pass through. The support block 41 is used to support and fix the forward and reverse spiral screw rods 4 to ensure its stability during rotation.

[0034] In some embodiments, a clamping strip 51 is provided on the top of the clamping block 5, near the support block 41. The clamping strip 51 cooperates with the clamping block 5 to form a stable clamping groove for stably clamping the workpiece or mold to be stamped. The presence of the clamping strip 51 increases the clamping area, improves the reliability and stability of the clamping, prevents the workpiece from shifting during the stamping process, and thus ensures stamping accuracy and operational safety.

[0035] While the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited thereto. Within the technical scope of the present invention, various simple variations of the technical solution of the present invention may be made. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as disclosed herein and fall within the scope of protection of the present invention.
