[0002] The production process of metal products mainly includes: raw material preparation, raw material cutting, surface treatment, welding and other processes. Among them, raw material cutting is a key process link, which is used to cut raw materials or semi-finished products into the required size and shape. The existing common cutting methods include: saw cutting, flame cutting, plasma cutting, laser cutting, etc. Among them, saw cutting uses a high-speed rotating saw blade to cut the raw material. This is a relatively common cutting method that is suitable for a variety of metal materials.

[0003] During the saw cutting process, uneven stress distribution of the raw materials, tool wear, improper cutting speed or material properties can easily cause curling on the surface of the cut metal raw materials. These curling on the surface of the metal raw materials seriously affect the subsequent product production process. Therefore, after metal cutting, the cut raw materials need to be polished, which greatly increases the production cost. In addition, it is very easy for workers to be cut when handling the cut raw materials, endangering their lives.

[0004] Therefore, the utility model provides a cutting mechanism for producing metal products. Utility Model Content
