Hot forming process for spoke

Abstract

This invention discloses thermoforming spoke technique and comprises steps: blanking, chamfering, rolling, welding, grinding, expanding, heating, forming, lathing center hole, punching screw hole, lathing surface and end face, trimming and packaging. It increases the utilization of steel material and economic benefit, decreases cost, enhances intensity of stretch-proofing and resistance to bending, and prolongs service life.

Description

technical field

[0001] The invention relates to a processing technology of a wheel spoke, in particular to a technology of thermoforming a wheel spoke. Background technique

[0002] The wheel is a load-bearing rotating component between the tire and the axle. It usually consists of two main components, the steel ring and the spoke. The spoke is the supporting part on the wheel between the axle and the rim, so the spoke performance is good. Damage directly affects the operation and safety of the vehicle, and also directly affects the carrying capacity of the vehicle. It has been reported that in recent years, the cracks in the spoke plate holes of truck wheels have become serious and have become the main failure affecting the use of trucks. This is also the case with other vehicles.

[0003] At present, the domestically produced spokes all adopt the cold press forming process, which has a relatively low utilization rate of steel, which makes the production cost relatively hi...
