Arched cross beam forming die

The utility model provides an arch-shaped cross beam forming die, relates to the field of dies, and aims to solve the problems that when an existing arch-shaped cross beam forming die is used, slight dislocation is prone to occurring, and a structure for assisting position correction is lacked. Comprising a body; the main body is a lower die body, the upper die is installed at the top end of the main body, the two sides of the upper die are each provided with an auxiliary part, an insertion groove is formed in each auxiliary part, the top end of each insertion groove is of a rectangular structure, and the two sides of the bottom of each insertion groove are of an inclined structure. When the arch-shaped cross beam is pressed, the side rods can be inserted into the inserting grooves, due to the fact that the two sides of the bottoms of the inserting grooves are of inclined structures, after slight dislocation occurs between the main body and the upper die, the positions of the bottoms of the inserting grooves
