An aluminum alloy round bar material is conveyed to a multi-directional extrusion die after being heated; punches are arranged at the two ends of the multi-directional extrusion die, and a transversely protruding profile cavity is arranged in the middle of the multi-directional extrusion die; the aluminum alloy round bar material is deformed under the action of the punches at the two ends after die combination, and a transverse protrusion is formed in the middle; the aluminum alloy round bar material is bent along the portion of the transverse protrusion in the middle through a bending die, and a preforming blank similar to the outline of an aluminum alloy control arm is formed and is prepared for a subsequent die forging forming process. The multi-directional extrusion preforming method is high in material utilization rate, is stable in performance and realizes automation easily, and formed products are applied to a steering control system of a high-end passenger car.
Description
Technical field
The present invention relates to metal forming technology in a kind of material processing, particularly relate to the method for the multidirectional extruding base of a kind of Complex Aluminum Alloy control arm forging.
Background technology
Aluminum alloy control arm is key components and parts in high-end passenger car steering, has very high requirement to intensity and interior tissue, all adopts forging forming method production aluminum alloy control arm forging at present.Through metal forming operation production aluminum alloy control arm forging such as base, blocking, finish-forging, trimmings.Wherein blank-making technology is the key that this type of Complex Aluminum Alloy control arm is shaped, and the surface quality of prefabricated blank, contour shape and interior tissue have very important impact on follow-up forging and forming technology, especially affect forging surface quality and interior tissue.
As shown in Fig. 1 a, Fig. 1 b, Fig. 1 c, it is one typical Complex Aluminum Alloy control arm forging drawing.
In prior art, adopting cross wedge rolling or roll-forging process base, all there is certain technical bottleneck in two kinds of base modes.Cross wedge rolling surface quality is bad, affects whole forging surface quality; Roll forging lengthwise dimension inaccuracy, is unfavorable for realizing automation.The prefabricated blank that two kinds of base modes are produced is revolving body, must through bending, flatten, all multiple operation of post bake can enter follow-up forging process, affect production efficiency.Simultaneously precut blanks shape and blocking cavity shape matching degree poor, require very high to blank putting position when blocking is shaped, be unfavorable for realizing automated production, in order to head it off, blank diameter need be strengthened, blocking is shaped to blank putting position requirement reduction, causes stock utilization sharply to decline, increase forging production cost.
Summary of the invention
The object of this invention is to provide that a kind of stock utilization is high, stable performance, the method for the multidirectional extruding base of Complex Aluminum Alloy control arm forging that easily is automated.
The object of the invention is to be achieved through the following technical solutions:
The method of the multidirectional extruding base of Complex Aluminum Alloy control arm forging of the present invention, described Complex Aluminum Alloy control arm forging comprises the first arm and the second arm that intersect vertically, in arc line type, lateral outer lug inside the position that described first arm is crossing with the second arm, comprise step:
After being heated by aluminum alloy round bar, send into multidirectional extrusion die;
The two ends of described multidirectional extrusion die are respectively equipped with drift, and middle part is provided with the die cavity laterally protruded;
After matched moulds, aluminum alloy round bar starts distortion under the drift effect at two ends, forms horizontal projection in the middle part of it;
Afterwards, being bent by the position of bending mould along middle part lateral projection, forming the prefabricated blank similar to aluminum alloy control arm appearance profile, for entering follow-up die forging forming process.
As seen from the above technical solution provided by the invention, the method for the multidirectional extruding base of Complex Aluminum Alloy control arm forging that the embodiment of the present invention provides, after first being heated by aluminum alloy round bar, sends into multidirectional extrusion die; After matched moulds, aluminum alloy round bar starts distortion under the drift effect at two ends, forms horizontal projection in the middle part of it; Bent by the position of bending mould along middle part lateral projection afterwards, form the prefabricated blank similar to aluminum alloy control arm appearance profile, for entering follow-up die forging forming process, stock utilization is high, stable performance, easily be automated, and formed product is applied to high-end passenger car steering control system.
