[0002] Angle steel is widely used in various building structures and engineering structures. It is a material often used in the production process. After purchasing, angle steel needs to be cut and processed for use.

[0003] Traditional angle steel cutting usually adopts sawing cutting, grinding wheel cutting and flame cutting. Saw cutting can cut angle steels of various cross-sections, but the cost is high. Grinding wheel cutting can only cut angle steels of small cross-sections. The surface is formed after flame cutting and needs to be polished later. The existing angle steel cutting method usually uses hydraulic press for cutting, but the cutting section width is not adjustable, and the angle steel can only be cut vertically. The angle steel needs to be pushed to the front of the hydraulic press manually. The length of the angle steel cut by manual pushing is different, which is not only time-consuming and laborious, but also has low precision and is prone to casualties and lacks safety.

[0004] Therefore, we designed an angle steel corner shearing equipment. Utility Model Content
