[0002] Special-shaped steel is the abbreviation of complex and special-shaped cross-section steel. It is a type of steel and is different from simple cross-section steel. According to different processes, special-shaped steel can be divided into hot-rolled special-shaped steel, cold-drawn (cold-drawn) special-shaped steel, cold-bent special-shaped steel, welded special-shaped steel, etc. Among them, when cold-drawing steel, a special-shaped steel forming mold is required to cold-draw the steel to form special-shaped steel.

[0003] After searching, the Chinese patent announcement number: CN210358573U discloses a cold drawing die for processing special-shaped steel, including a disc-shaped die body, a cross-shaped forming hole on the die body, and forming rollers in the four branch cavities of the forming hole. Its characteristics are that there are U-shaped plates in the branch cavities of the forming holes, and there are slide grooves on the side walls of the forming hole branch cavities corresponding to both sides of the U-shaped plate. The U-shaped plate and the slide groove are matched in a longitudinal sliding manner along the forming hole branch cavity. There is a screw between the bottom of the forming hole branch cavity and the outer circular surface of the die body. The screw is arranged along the longitudinal direction of the corresponding forming hole branch cavity, one end of the screw is located outside the die body, and the other end is located in the corresponding forming hole branch cavity. The U-shaped plate closing part corresponding to the screw has a screw hole, and a hexagonal rotating block is integrally connected to the extended end of the screw.

[0004] Although this technology can conveniently adjust the distance between the forming rollers by rotating the screw to adapt to different drawing passes, in actual use, the distances between the forming rollers in the four directions are adjusted independently, which may easily lead to unequal distances between the forming rollers and the center, which may cause the shape of the special-shaped steel to deviate during cold drawing, resulting in inaccurate forming and reduced product quality. Therefore, a special-shaped steel forming mold is proposed to solve the above problems. Utility Model Content
