An eye-protecting punching device for shoemaking

Abstract

The invention discloses an eye-protecting punching device used for shoemaking. The eye-protecting punching device used for shoemaking comprises an installation frame, wherein the installation frame isof a C-shaped structure, an upper half portion and a lower half portion are arranged in the installation frame from top to bottom in sequence, the upper half portion and the lower half portion are ofthe same structure, the upper half portion and the lower half portion are symmetrically installed on two sides of the middle surface, in a vertical direction, of the installation frame, the lower half portion comprises a working table and a lifting table, the lower surface of the working table is connected with the bottom wall of the installation frame through first air cylinders, the lifting table is arranged under the working table, and the lifting table is in parallel with the working table. According to the eye-protecting punching device used for shoemaking, by squeezing and fixing a material around a hole, tensile force born by the surrounding material during punching is reduced, tearing of the surrounding material is avoided, moreover, an automatic feeding mode is adopted, cloth isautomatically fed, manual feeding is not needed, and thus an operator does not need to observe closely, so that the situation that waste which is splashed out enters eyes is avoided, and visual impairment is avoided.

Description

technical field [0001] The invention relates to the technical field of shoemaking machinery, in particular to an eye-protecting punching device for shoemaking. Background technique [0002] In the process of shoemaking, it is often necessary to punch holes on the surface of the material. Due to the different materials, some materials will be torn around the holes when the hole is punched, resulting in scrapped materials. The position of the hole is accurate, and when moving the material, the worker needs to observe at a close distance, and the splashed waste will enter the operator's eyes, causing damage to the operator's vision. Therefore, it is necessary to reduce the tearing probability of the hole without damaging the Punching device for operator's eyes. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an eye-protecting punching device for shoemaking. By squeezing and fixing ...
