DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The following is combined with Figure 1-5 To further explain this application in detail,

[0027] The embodiment of the present application discloses a positioning punching die for a metal bracket of an automobile wiring harness, comprising an upper die head 1 and a lower die head 7, wherein the lower die head 7 is fixed on a lower die base 8, and the lower die base 8 is provided with a pushing cylinder 12, and the pushing cylinder 12 pushes the finished metal bracket 2 in the bending groove 11 to the inclined blanking plate 19 through a pushing block 27 at its end, thereby realizing the automatic discharge of the metal bracket 2 after punching and bending, and the bending station of the bending groove 11 is aligned with the bending die head 6 on the upper die head 1, and the bending die head 6 is used to cooperate with the metal bracket 2 for bending and forming;

[0028] The upper die head 1 is provided with a punching head 3 for punching holes on both sides of the metal bracket 2 and a punching head 5 for punching and cutting the metal plate 4. The metal plate 4 (the raw material of the metal bracket 2) to be punched and bent is loaded through a guide channel 9, and after being loaded to the punching and cutting stations on the lower die head 7 and the lower die base 8, the metal plate 4 is punched by the punching head 3, and the metal plate 4 is punched and cut by the punching head 5 to form an independent metal bracket 2;

[0029] The cooperation of the upper die head 1 and the lower die head 7 realizes the automatic punching and bending of the metal bracket 2. The lower die head 7 is fixed on the lower die base 8, and the push cylinder 12 pushes the finished metal bracket 2 to the inclined unloading plate 19 through the push block 27 to realize automatic unloading. The bending station of the bending groove 11 is aligned with the bending die head 6 on the upper die head 1, and cooperates with the metal bracket 2 to bend and form. The upper die head 1 is provided with a punching head 3 and a punching head 5, and the metal plate 4 is fed to the lower die head 7 through the guide channel 9. After the action of the punching head 3 and the punching head 5, an independent metal bracket 2 is formed.

[0030] Through the design of the mold, the automatic punching and bending of the metal bracket 2 is realized to improve the production efficiency. The mold can accurately position the metal bracket 2 to ensure the accuracy and consistency of punching and bending. The mold can ensure the stable processing quality of the metal bracket 2 and reduce the impact of human factors on product quality. Automated production reduces manual operations, saves labor costs, and improves production efficiency and benefits.

[0031] Specifically, the bending groove 11 is provided on the lower die base 8, and the bending groove 11 and the bending station thereon are aligned with the opening 10 on the lower die head 7 and cooperate with the bending die head 6 to bend and form the metal bracket 2;

[0032] The alignment of the bending groove 11 and the bending station ensures the precise position of the metal bracket 2 during the bending process, avoiding deformation or damage of the bracket due to position deviation. Since the bending die 6 directly cooperates with the opening 10 on the lower die 7, no additional adjustment or positioning steps are required, thereby speeding up the production speed. The bending groove 11 and the bending station fixed on the lower die base 8 provide stable support for the bending operation, ensuring the stability and repeatability of the bending process. Designing the bending groove 11 on the lower die base 8 can make the mold structure more compact, reduce the overall size of the mold, and facilitate installation and maintenance.

[0033] Specifically, the guide channel 9 is formed by the concave groove opened at the bottom of the lower die head 7 and the lower die base 8, and the guide channel 9 is used to cooperate with the metal plate 4 to guide the feed;

[0034] The guide channel 9 provides an accurate feeding path for the metal plate 4, ensuring the correct position of the metal plate 4 before entering the bending station. Through the precise guidance of the guide channel 9, the deviation of the metal plate 4 during the feeding process is reduced, and material waste is reduced. The design of the guide channel 9 simplifies the loading process, so that the metal plate 4 can reach the bending position quickly and accurately, thereby improving production efficiency. Accurate guidance helps to maintain the straightness of the metal plate 4 during the bending process and improves the quality of the finished product.

[0035] Specifically, the guide rod 13 at the bottom of the upper die head 1 cooperates with the lower die head 7 for guidance during the stamping process. When the punching head 3, the cutting head 5 and the guide rod 13 on the upper die head 1 are stamping, they cooperate with the lower die head 7 and the guide hole 14 on the lower die base 8 to be inserted. The waste after stamping and cutting can be discharged through the guide hole 14. The guide hole 14 is connected to the rectangular guide hole 15 on the bottom support 16 of the lower die base 8, and the waste is then discharged through the rectangular guide hole 15.

[0036] The guide rod 13 at the bottom of the upper die head 1 cooperates with the lower die head 7 for guidance, and the punching head 3, the punching head 5 and the guide rod 13 are interlaced and cooperated during the stamping process, so as to achieve accurate guidance and stamping of the metal plate 4. The waste is discharged through the guide hole 14 and the rectangular guide hole 15, which avoids the impact of the waste on the production environment and improves the production efficiency and safety. The accurate guidance and stamping process can speed up the production speed and improve the production efficiency. The accuracy of guidance and stamping helps to reduce the occurrence of stamping waste and improve the product quality. The waste is discharged through the specially designed guide hole 14 and the rectangular guide hole 15, which avoids the impact of the waste on the production environment and is beneficial to environmental protection. The design of the guide hole 14 and the rectangular guide hole 15 simplifies the mold structure and reduces the manufacturing cost and maintenance difficulty of the mold.

[0037] Specifically, the support 16 is fixedly connected to the base 18 through two upright blocks 17, and the top four corners of the base 18 are fixedly connected to the top plate 21 through support rods 20. The upper die head 1 is pushed downward by the punching cylinder 22 on the top plate 21 to cooperate with the lower die head 7 and the lower die base 8 to punch, cut and stamp the metal plate 4. During the punching, cutting and stamping process, the guide rod 24, the guide sleeve 25 and the spring 26 are used for buffering and guiding, wherein the guide rod 24 is fixed to the guide rod 24 on the support 16, and the guide sleeve 25 is fixed to the upper die base 23.

[0038] The punching cylinder 22 on the top plate 21 pushes the upper die head 1 downward to cooperate with the lower die head 7 and the lower die base 8 to punch, cut and stamp the metal plate 4. During the punching, cutting and stamping process, the guide rod 24, the guide sleeve 25 and the spring 26 play a role of buffering and guiding to ensure the accurate position and stability of the metal plate 4 during the stamping process.

[0039] The punching cylinder 22 pushes the upper die head 1 downward to accurately control the positions of punching, cutting and stamping, ensuring the accuracy of the stamping process. The punching cylinder 22 of the top plate 21 pushes the upper die head 1 downward, realizing the automation of punching, cutting and stamping, improving production efficiency, and the automated stamping process reduces manual operation and saves labor costs. The buffering guidance of the guide rod 24, the guide sleeve 25 and the spring 26 reduces the wear of the mold and equipment during the stamping process and extends the service life. The precise stamping process helps to maintain the consistency and quality of the product. The automated stamping equipment reduces manual contact during operation and improves production safety.
