Embodiment Construction

[0047] Below in conjunction with accompanying drawing, take the 909 type automobile steering knuckle exported to India TATA Automobile Group Company as an example to illustrate the present invention, as figure 1 , figure 2 , the steering knuckle die forging forging process is as follows:

[0048] 1. Cutting: Adopt GB4025C band saw machine to cut φ100 round steel with a length of 248±2mm;

[0049] 2. Heating: Use KGPS800-1 medium frequency induction heating furnace to heat the round bar to the temperature required by the forging process;

[0050]3. Blank pre-forging and forming forging: 3T die forging hammer is used to forge the four-step process of pulling out the long rod, flattening the ear, vertically splitting the billet and pre-forging. The four-step process forging is located on a multi-cavity mold body conduct;

[0051] The billet pre-forging die and its partial cross-section are as follows: Figures 14 to 20 As shown, it is drawn out in the rod cavity 10, the late...

Abstract

A middle-duty and heavy-duty automobile knuckle stamp forging extruding compound technology overcomes the disadvantages of low material utilization and large device investment of the traditional production technology, utilizes flexibility of preforming by a stamping hammer and structure characteristic of a press extrusion die and adopts stamping hammer production technology and press extrusion compound technology. The main technical scheme includes a series of technical measures of vertically splitting of blank material by mould with V-shaped cutting edge and locally enclosed structure, preforging of cavity damping stripe, finish forging of locally enclosed structure, hot extrusion forming of steering space and the like, parameter requirements and corresponding moulds and devices. The invention has the characteristics that device investment of stamping hammer production technology is small, structure is simple, and equipment manufacturing period is short; production technological flow is reasonable and processing is easy; and the invention also has the characteristics that product quality is good and productivity is high; and material utilization is obviously higher than that of any original knuckle processing technology and production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the forging processing technology in the field of mechanical manufacturing, in particular to the forging technology of automobile steering knuckle die forging in which the parting surface is perpendicular to the flange surface. Background technique [0002] The steering knuckle is the key structural part of the front axle assembly and the front suspension system of the car. It connects the front axle and the steering system, not only bears the entire weight of the car, transmits the steering power, but also bears the impact from the ground and the lateral braking of the wheels. The load generated by the load is a powerful guarantee for the safety of the car in driving. Steering knuckles are security parts with complex shapes in automobile chassis components. Due to the rapid development of my country's automobile industry, the production and development of steering knuckle products have also made great progress, which has brou...
