A metal banding punch and round die

Abstract

This utility model discloses a metal band punching die, including a base, a forming die assembly mounted on the top of the base, a stamping mechanism mounted on the base at the forming die assembly, and side forming assemblies mounted on both sides of the base at the forming die assembly. The forming die assembly includes a base, with two movable forming claws rotatably mounted in the middle of the base. The two movable forming claws are symmetrically arranged, and a reset assembly for acting on the movable forming claws is provided below the movable forming claws on the base. The stamping mechanism includes a punch, which is a cylindrical structure with a flat surface cut off. This utility model, with two side forming assemblies symmetrically mounted on both sides of the forming die assembly, solves the problem of insufficient bending effect at the end. A push-pull cylinder drives the forming plate to reciprocate, applying lateral pressure from both sides to the end of the band during the main stamping process, supplementing the forming force, offsetting the insufficient forming caused by the pre-reserved space for demolding, and ensuring that the bending effect at the end meets the standard.

Description

Technical Field

[0001] This utility model relates to the field of band punching technology, specifically a metal band punching die. Background Technology

[0002] During the forming process, the overlapping parts of the ear circles of the clamp are prone to misalignment, leading to localized stress concentration during use. Furthermore, ensuring a proper fit between the overlapping ear circles is difficult, causing stress during welding and affecting the clamp's service life. To address these challenges in clamp forming, a specialized circular tooling was designed.

[0003] Existing punching dies require space to be left at the slit for demolding, which results in the bending effect at the slit not being achieved. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] Please see Figure 1-7 In this embodiment of the utility model, a metal band punching die includes a base 1, a forming die assembly 2 is installed at the top of the base 1, a stamping mechanism 3 is installed on the base 1 at the forming die assembly 2, and side forming assemblies 4 are installed on both sides of the base 1 at the forming die assembly 2; the forming die assembly 2 includes a base 21, and two movable forming claws 22 are rotatably installed in the middle of the base 21. The two movable forming claws 22 are symmetrically arranged and rotatably installed in the middle of the base 21, and directly contact the metal band through the arc-shaped working surface at the top to achieve preliminary bending and forming; The bottom is provided with a rotating seat 221, which cooperates with the rotating groove of the base to ensure rotational flexibility; the base 21 is located below the movable forming claw 22 and is provided with a reset component that acts on the movable forming claw 22. The reset component consists of a reset spring 24 and a push rod 25. The reset spring 24 is located below the push rod 25. After stamping, the spring force pushes the push rod to reset the movable forming claw, which facilitates the demolding of the band; the stamping mechanism 3 includes a punch 34. The punch 34 is a cylindrical structure with a flat surface cut to adapt to the curved surface forming requirements of the band. It provides the main forming pressure to the band by pressing vertically downward.

[0023] The movable forming claw 22 includes a rotating seat 221. The base 21 has a rotating groove that cooperates with the rotating seat 221. A limit plate 23 is installed on the base 21 outside the movable forming claw 22.

[0024] The side forming assembly 4 includes a support base 41, a push-pull cylinder 42, and a forming plate 43. The push-pull cylinder 42 is installed at the top of the support base 41. The push-pull cylinder 42 drives the forming plate 43 to move back and forth. The two side forming assemblies 4 are symmetrically installed on both sides of the forming mold assembly to solve the problem of insufficient bending effect at the closing point. The push-pull cylinder drives the forming plate to move back and forth. During the main stamping process, lateral pressure is applied from both sides to the closing point of the band to supplement the forming force, offset the insufficient forming caused by the space reserved for demolding, and ensure that the bending effect at the closing point meets the standard.

[0025] The stamping mechanism 3 includes a bracket 31 and a limiting seat 35. A lifting cylinder 32 is installed at the top of the bracket 31. The lifting cylinder 32 is connected to the punch 34 through a lifting rod 33. The punch 34 and the bracket 31 are slidably connected by a slider and a linear guide rail. The lifting cylinder drives the punch to move up and down through the lifting rod. The punch and the bracket are slidably connected by a slider and a linear guide rail to ensure the stability and verticality of the stamping process. The limiting seat 35 limits the maximum downward stroke of the punch to avoid over-stamping.

[0026] The working principle of this utility model is as follows: the metal band to be processed is placed between the movable forming claws of the forming mold assembly; the lifting cylinder drives the punch to press down, and the main pressure is applied to the band through the special planar structure, which, together with the movable forming claws, achieves initial bending; the side forming assemblies on both sides are started simultaneously, and the push-pull cylinder pushes the forming plate closer to the closing point, applying lateral pressure to ensure that the closing point is bent in place; the punch is lifted and reset, the forming plate of the side forming assembly is retracted, and the spring of the reset assembly pushes the push rod to reset the movable forming claws, thus completing the demolding.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
