Product Description Figure 8 knot steel bar making machine commonly used on construction sitesThe splayed bar forming and pressing machine is mainly used in tunnel engineering, culvert engineering, highway engineering, railway engineering, concealed engineering, mines, coal mines, highways, high-speed rail and other projects for the production of tunnel grid arch frames.At present, during the construction of highway projects, bridges, tunnels, high-speed railways, etc., a large number of grid arches are needed to reinforce and support the circular shape of the tunnel. The grid arches are welded together with ring-shaped main steel bars and eight-shaped steel bars. Therefore, a large amount of splayed steel bars are needed during construction.The quality of the figure-eight steel bars directly affects the quality of the grid arch. The grid arch is used to support and reinforce the surrounding rock, and is in close contact with the ground and closed with sprayed concrete to form a ring.Only then can the next step of excavation work be carried out.Its function is to strengthen the initial support of the tunnel, and to ensure safe construction operations in the next step of excavation.1. Processing method:Determine the cutting length according to the figure-eight knot grid frame drawing → bend the sheared steel bars → weld the bent steel bars → use hydraulic equipment for plane extrusion → weld the extruded steel bars → complete the welding The plane 4 figures are extruded on the facade → the double figure 8 are welded to form a complete figure 8 knot.The steel brackets used to support caves or bunkers are generally made of steel or steel bars according to a certain arc and length. They are made into individual components and then installed at the construction site. After that, the anchor rods are installed and the connecting steel bars are welded. The pieces are welded, and concrete anchor spraying is carried out to complete the initial support during the construction.2. Eight-shaped rebar forming machine operation guideMold steel can be roughly divided into three categories: cold-rolled mold steel, hot-rolled mold steel and plastic mold steel, which are used for forging, stamping, cutting, die-casting, etc. Since various molds have different uses and complex working conditions, the steel used for molds should have high hardness, strength, wear resistance, sufficient toughness, and high hardenability and quenching properties according to the working conditions of the molds they are made of. Hardness and other process properties. Due to the different uses and complex working conditions of these types of molds, the performance requirements for mold steel are also different.The splayed bar forming machine is mainly used to process the splayed bar embossing of the longitudinal connecting bars, which are the core components of the tunnel grille arch frame and arched frame grille structure. This equipment has the advantages of high forming accuracy and fast production efficiency. The steel brackets used to support caves or bunkers are generally made of steel or steel bars according to a certain arc and length. They are made into individual components and then installed at the construction site. After that, the anchor rods are installed and the connecting steel bars are welded. The steel mesh is welded, and finally concrete is sprayed.3.
