Description

Technical Field

[0001] The utility model belongs to the field of processing, and particularly relates to a tool punch for quickly punching special-shaped cloth. Background Art

[0002] At present, some product parts have special shapes, and ordinary punches cannot complete the forming work in one go. In order to achieve the goal of punching multiple parts at a time and improve the processing efficiency, it is necessary to design a tooling punch that can quickly punch special-shaped fabrics. Utility Model Content

[0003] The purpose of the utility model is to provide a tool punch for punching special-shaped cloth. By using the device, the relevant products can be processed and formed in one step.

[0004] The utility model is achieved through the following technical solutions:

[0005] A tool punch for quickly punching special-shaped fabrics includes an upper cover, a punch component, a center hole rod, a base, a support rod, and a spring. The punch component is connected to the upper cover by bolts, and the center hole rod is connected to the upper cover by threads. The base is placed on the workbench of a hydraulic press, and a layer of cardboard is laid on the base. The fabric is placed on the cardboard on the base. The assembled upper cover is placed above the fabric, and the support rod is inserted into the hole of the base. The support rod and the base are interference fit, and the support rod cannot rotate at will. The spring is sleeved on the outer diameter of the support rod, and the spring is assembled in the countersunk hole of the upper cover.

[0006] Beneficial effects of the utility model

[0007] The utility model discloses a tool punch for punching special-shaped fabrics, which can complete the molding of related products in one step. The manufacturing process is simple and the process is greatly saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] A tool punch for quickly punching special-shaped fabrics, comprising an upper pressing cover 1, a punch component 2, a center hole rod 3, a base 4, a support rod 5, and a spring 6.

[0016] ① The punch component 2 is connected to the upper cover 1 through bolts, and the center hole rod 3 is connected to the upper cover 1 through threads.

[0017] ②Cut the fabric to the outer dimensions according to the drawing size.

[0018] ③ Place the cloth on the base 4, which is made of wood and covered with a layer of cardboard. The cloth is placed on the cardboard. The support rod 5 and the base 4 are interference fit, and the support rod 5 cannot rotate at will. The spring 6 is sleeved on the support rod 5. The spring 6 is assembled in the countersunk hole of the upper cover 1 to ensure that the upper cover 1 does not move before pressing.

[0019] ④ Place the tool on the workbench of the hydraulic press, turn on the press, and press the upper platen downward to complete the punching process. Due to the limited length of the center hole rod 3, a small portion of the fabric will not be able to complete the punching process in one go. This portion of the fabric needs to be accumulated together and then the center hole punching process is carried out last.

[0020] Place the base 4 on the workbench of the hydraulic press, insert the support rod 5 into the holes at the four corners of the base 4, and put the spring 6 on the outer diameter of the support rod 5. Place the cardboard cut into squares on the boss of the base 4, and place 3 to 4 layers of cardboard. Place the cloth cut into squares on the cardboard, and pay attention to aligning the periphery of the cloth with the periphery of the boss to prevent the cut product from being unqualified. Place the assembled upper cover 1 on top of the cloth, and insert the spring 6 into the countersunk hole of the upper cover 1. Turn on the hydraulic press, and the press plate applies pressure to the upper cover 1. The punch 2 and the center hole rod 3 on the upper cover 1 cut the cloth into the shape of the finished part. Due to the limited length of the center hole rod 3, a small part of the cloth cannot be punched in one time during the punching process. This part of the distributed material needs to be accumulated together, and then the center hole punching is performed.
