[0002] Steel grating is an open steel structure that is made of load-bearing flat steel and cross bars that are orthogonally combined at a certain distance and fixed by welding or pressing. The cross bars are generally made of twisted square steel, but round steel or flat steel can also be used. The materials are divided into carbon steel and stainless steel. Steel grating has a wide range of uses and is mainly used in load-bearing areas.

[0003] The production process of steel grating requires punching equipment to punch holes in the steel grating. Existing punching devices often have difficulty achieving precise positioning, resulting in low production efficiency. In addition, vibration occurs during the punching process, and it is difficult to eliminate the vibration source, causing noise pollution and affecting the working environment. In view of this, we propose a new punching device for steel grating production to solve the above problems. Utility Model Content
