Problems solved by technology
However, in the process of extrusion processing, due to the small distance between the stations, the time interval for the axle housing billet to be extruded by two adjacent stations is very short, resulting in the cold extrusion of the axle housing formed by the extrusion device. The rectangular part of the billet has cracks or the dimensions do not match, and when a certain station of the extrusion die is extruding the cylindrical part of the axle housing blank, other stations of the extrusion die are in an idle state. In this case, On the one hand, the waiting time for the next axle housing billet to be extruded is lengthened, on the other hand, the utilization rate of the extrusion die is reduced, resulting in low production efficiency of the extrusion device

Embodiment Construction
[0028] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is further described:
[0029] like Figure 1 to Figure 4 As shown, it is the extrusion device of the present invention. In this embodiment, it is a roller press, which can be used to process the axle housing blank 4 by cold extrusion, hot extrusion or warm extrusion. The device defines a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The extrusion device includes: frame 1, conveying assembly 5, die assembly 2 and pick and place assembly 3, conveying assembly 5, die assembly 2 and pick and place assembly 3 are installed on rack 1.
[0030] like figure 1 , figure 2 As shown, the conveying assembly 5 is an idler roller, which can move in the longitudinal direction and is used for conveying the axle housing blank 4 to the mold assembly 2 . The axle housing blank 4 is a round tube, the middle of which is a fixed portion 42, and ...

The invention discloses an axle housing blank extrusion forming method and an extrusion device. The axle housing blank extrusion forming method comprises the following steps that S1, a round pipe is selected as an axle housing blank; s2, the axle housing blank is fed into an extrusion cavity of a first mold assembly, and a to-be-extruded part of the axle housing blank is subjected to extrusion machining, so that the to-be-extruded part on the axle housing blank is shrunk and deformed into a first forming part; s3, the axle housing blank is taken out of an extrusion cavity of the first mold assembly; s4, the axle housing blank is fed into an extrusion cavity of the second mold assembly, extrusion machining is conducted on the first forming part on the axle housing blank, and the first forming part on the axle housing blank is shrunk and deformed into a second forming part; and S5, the axle housing blank is taken out of the extrusion cavity of the second mold assembly. By means of the method, the time difference of transferring the axle housing blank from the first die assembly to the second die assembly is increased so as to provide deformation buffering time, and a plurality of axle housing blanks can be extruded and machined at the same time.
Description
technical field [0001] The invention relates to the technical field of extrusion processing of auto parts, in particular to a method and an extrusion device for the extrusion of axle housing blanks. Background technique [0002] The rectangular part of the axle housing blank of the automobile can be cold-extruded into the rectangular part by the extrusion device. The existing extrusion device includes a pusher, and the pusher includes a shell and a In the extrusion die in the shell, there are multiple groups of rollers arranged in the extrusion die along the extrusion direction, and each group of rollers forms an extrusion cavity, and in the extrusion direction, the multiple extrusion cavities of the extrusion die gradually shrink To form a gradient extrusion cavity, that is, each extrusion cavity forms an extrusion processing station, multiple extrusion processing stations are integrated in the same mold, and in order to shorten the processing process, the stations are cl...
