Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a galvanized sheet metal punching device. Background Art

[0002] At present, galvanized sheets are often used to make various rail profiles, and holes need to be punched on the edges of the profiles for installing other components or splicing rails to improve their practicality. Punching technology is commonly used during processing. A continuous roll of galvanized sheet material is flattened and punched through a punching machine. Existing punching is often achieved by using a punching table at the bottom, a punching rod at the top, and a clamping mechanism around the punching rod. The galvanized sheet can be clamped and fixed during punching, but the galvanized sheet is easily lifted up when it is lifted up and pulled out, causing the horizontal position of the galvanized sheet to shift, which can easily lead to inaccurate distances between holes and affect the yield rate of the product.
