Knuckle composite mold and technology

Abstract

The invention relates to the technical field of knuckle production and fabrication, in particular to a knuckle composite mold and technology. According to the composite technology, a forge piece is positioned in a calibration lower mold to drive an upper mold plate to move downwards. The forge piece is wrapped and compressed by a calibration upper mold and the calibration lower mold, and thereforea cube head of the forge piece is subjected to sustained torsional deformation until the cube head is formed. During the torsional deformation process of the cube head, edge cutting is conducted through cooperation of an edge cutting concave mold and an unloading plate. After edge cutting, the upper mold plate continuously moves downwards, the calibration upper mold and the calibration lower moldcontinuously wrap and compress the forge piece to complete overall fine forming of the forge piece. The knuckle composite mold and technology has the beneficial effects that the cube head of the knuckle is formed and positioned through torsional deformation, cutting machining is not required, processes are simplified, efficiency is improved, and the cost is lowered; and the edge cutting process is accomplished simultaneously during the knuckle wrapping compressing forming process, edge cutting deformation is avoided, and the product quality and size accuracy are guaranteed.

Description

technical field [0001] The invention relates to the technical field of steering knuckle production and manufacturing, in particular to a steering knuckle composite mold and technology. Background technique [0002] The car steering knuckle is one of the main safety parts of the car steering front axle assembly. It effectively transmits the angle value of the steering wheel to the front wheel of the car, controls the direction of the car, and bears the variable impact load on the front of the car. Therefore, the steering knuckle not only requires reliable strength, but also must ensure its high machining accuracy. However, since the steering knuckle itself is a high-difficulty and complex forging of branches, which integrates the structural characteristics of four types of parts such as shafts, holes, disc rings, and yokes, the structure of the slender arm steering knuckle is more complicated, and the spatial dimension accuracy of the arm is required. higher. In actual prod...
