Description

Technical Field

[0001] The utility model relates to the technical field of steering knuckle processing, in particular to a steering knuckle upsetting device. Background Art

[0002] The steering knuckle (also known as the "knuckle") is one of the important parts in the steering axle of the car. Its function is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to steer the car. When the car is driving, it is subjected to variable impact loads, so it is required to have very high strength.

[0003] When processing the steering knuckle, the bar stock is generally upset first, and then subjected to subsequent extrusion, pre-forging, final forging and other processing. Some also require local upsetting. During the above processing, in order to ensure smooth processing of the steering knuckle, the steering knuckle needs to be clamped and positioned. The traditional clamping structure generally uses a pair of clamping arms to directly clamp. However, during the local upsetting processing of the steering knuckle, the steering knuckle is basically formed after extrusion, pre-forging, final forging and other processing. The formed steering knuckle has many pin arms and protruding connecting arms, and the whole is irregular in shape. It is difficult to achieve the expected clamping effect by only using a pair of clamping arms to directly clamp the irregular steering knuckle for local upsetting, and it is easy to fall off, affecting the local upsetting processing of the steering knuckle. In view of this, the present application proposes a steering knuckle upsetting device. Utility Model Content
