Abstract

The invention relates to a perforating device which comprises a worktable, wherein an annular groove and a pit are processed in the worktable; the pit is located in the middle position of the annular groove; a lifting table is positioned right above the annular groove; a central shaft and a fixed cover are concentrically mounted on the lower surface of the lifting table; a tool bit is fixed on the lower end of the central shaft; a through hole and a through hole I are processed in the fixed cover; a movable cover is mounted below the fixed cover out of the central shaft; the upper end of the movable cover is fixedly connected to a guide rod; the guide rod extends into the through hole I and is locked by a limiting block; a pressure spring is also arranged on the guide rod; an elastic ring is fixed at the lower end of the movable cover; a large-headed nail punctures a perforated position of a shell fabric; when the perforated position is moved under the tool bit, the large-headed nail sinks into the pit to be positioned; when the lifting table moves downward, the elastic ring is in contact with the shell fabric first and unfolds the shell fabric; and under shrinkage of the pressure spring, the tool bit enters the annular groove to perforate the shell fabric. The device is simple in structure, finishes the perforating operation of the shell fabric in advance, and is quite practical.

Description

technical field [0001] The invention relates to the field of fabric processing, in particular to a punching device. Background technique [0002] Suitcases, handbags and other bags are wrapped with fabrics. Since handles, universal wheels and other components need to be installed on the bags, it is necessary to punch holes in multiple positions on the fabric. The current processing method is generally after the fabric wrapping is completed. Relying on the matching mold to manually punch holes, this method is labor-intensive and low-efficiency, and because the fabric has actually been formed, the holes processed on the formed fabric are not beautiful. Because existing punching device all is to process lower die on the desktop, i.e. groove, impacts by upper die above, forms relative shearing, forming hole. In fact, the operator cannot accurately locate the position of the lower mold when punching holes, and the processed holes have certain errors. How to design a device to pe...
