Embodiment Construction

[0019] Refer to attached picture. The main body 101 of the square hole cross groove sleeve blank 100 manufactured by the present invention is a hollow cylinder, one end of the hollow cylinder is a hexagonal connection hole 102, the other end is a square connection hole 103, and the hexagonal connection hole 102 and the square connecting hole 103 respectively extend to the hollow cylindrical interior, basically extending to the middle of the cylinder, each side of the square connecting hole 103 has axial grooves, and the four axial grooves form a cross groove, and the shaft The groove is also stepped, and the side near the opening of the square connecting hole is a deep groove 104, and four deep grooves form a deep cross groove, and the side away from the opening of the square connecting hole is a shallow groove 105, and the four deep grooves form a deep cross groove. The shallow grooves form relatively shallow cross grooves, and the hexagonal connecting holes 102 and the squar...

Abstract

The invention provides a method for manufacturing a square hole cross-groove sleeve blank for vehicle repair. The square hole cross-groove sleeve blank for vehicle repair is manufactured through six die cold heading. A cross stepped groove is formed simultaneously in the cold extrusion molding process, a product surface is smooth, the dimensional precision is stable, the structure is firmer, the safety is high, the bearing capacity is high, and the quality is high; and in addition, a six-station automatic cold heading molding machine can be adopted for manufacturing, the machining speed is higher and is increased by 40 times than the previous speed, machining material losses are reduced, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of multi-station cold heading, in particular to a method for manufacturing a square-hole cross-recessed sleeve blank for auto repair. Background technique [0002] The main body of the square hole cross recessed sleeve blank for auto repair is a hollow cylinder, one end of the hollow cylinder is a hexagonal connecting hole, and the other end is a square connecting hole, especially each side of the square connecting hole has an axial direction. Groove, the four grooves form a cross groove, and the groove is also stepped, and the side close to the opening of the square connecting hole is a deep groove, forming a deep cross groove, and the side far away from the opening of the square connecting hole The side is a shallow groove, which is a relatively shallow cross groove, and the hexagonal connecting hole and the square connecting hole are coaxial and through. [0003] The semi-square hole cross-recessed sleev...
