Problems solved by technology

The shape of the front axle is complicated. Although the left and right shapes are symmetrical, its cross-section fluctuates greatly, especially the steel plate and the limit block have deep and narrow cross-sections, which bring difficulties to the forging process.
[0003] The traditional forging method is the multiple heating and multiple forging method. The front axle produced by the multiple heating and multiple forging method has the problems of uneven internal structure, low forming rate and low performance index, and the workpiece is heat treated after air cooling , not only the process is cumbersome, but also consumes a lot of energy

Abstract

The invention discloses an automobile front axle production line. An automatic sawing machine, an intelligent medium-frequency induction heating device, a forging and shaping device, a heat treatment intelligent automatic conveying device and a closed-loop heat preservation and heating heat treatment device are sequentially arranged; wherein the workpirces among the automatic sawing machine, the intelligent medium-frequency induction heating device and the forging and shaping device are conveyed by intelligent robot arms. The invention further discloses a processing method of the automobile front axle. The processing method comprises the following steps: blanking, heating, roll-extruding, press-bending, pre-forging, finish-forging, trimming, correcting and heat treatment. According to the invention, the blank workpiece is heated once and quickly molded, the processing steps are simplified, the internal structure uniformity, the performance index and the machining forming rate of the workpiece are improved, the energy consumption and the waste gas emission are reduced, the manual physical labor is reduced, and the processing cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of automobile front axle forging technology, in particular to an automobile front axle production line and processing method. Background technique [0002] The steering of the car is completed by the swing of the front axle assembly. The front axle is the main component of the front axle assembly. In addition to bearing the weight of the car, it also bears the vertical load, braking force, and lateral direction between the ground and the frame. Forces and bending moments caused by lateral forces are one of the important security parts that bear heavy loads on automobiles, and require high strength and fatigue life. The shape of the front axle is complex. Although the left and right shapes are symmetrical, its cross-section fluctuates greatly, especially the steel plate and the stop block have deep and narrow cross-sections, which bring difficulties to the forging process. [0003] The traditional forging method us...
