Abstract
A driving bridge shell for car is made up of a rectangular steel pipe through cutting short, slotting, shaping, welding triangular plate and finishing. Its advantages are high load power and strength, and beautiful appearance.
Description
The invention discloses a kind of new automobile driving axle housing and manufacturing process thereof, belong to vehicle driving axle housing and make processing technique field.
The autotruck driving axle housing of producing both at home and abroad mainly contains casting and two kinds of manufacture methods of punching press welding at present, and the former exists production environment to pollute, and product distortion difficulty can not be welded shortcomings such as auxiliary stand; The latter then needs large-scale pressing equipment, heating device, and production joint is many, hidden danger is many, and the axle housing distortion that the commissure stress causes is difficult for correcting, and profile is not attractive in appearance.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of produce pollution-free, intensity is high, the new automobile driving axle housing and the manufacturing process thereof of good looking appearance.
For achieving the above object, the technical solution used in the present invention is: a kind of new automobile driving axle housing, its characteristics are that it is to be processed by the steel pipe integral that a section is a rectangle.
The manufacturing process of above-mentioned new automobile driving axle housing be comprise successively that fixed length is got, middle part fluting, moulding, welding set square, fine limit work several steps, adopt the expansion method to carry out moulding, utilize former and equip the position integral body of to slot to expand into needed shape and size, weld again afterwards and fine limit work.
The present invention compared with the prior art, the good effect that has is, small investment, the efficient height, the size rectangular steel pipe of employing different section just can be produced the driving axle housing of various models, the production environment that had both overcome casting is polluted, do not need large-scale punching press, heating device again, product is an integral body, can weld various auxiliary stands in the above, the intensity height, good looking appearance.
The invention will be further elaborated below in conjunction with drawings and Examples.
Fig. 1 is a process sequence diagram of the present invention.
New automobile driving axle housing of the present invention is to be processed by the steel pipe integral that a section is a rectangle; Its concrete manufacturing process is followed successively by the first step as shown in Figure 1: the rectangular steel pipe length on demand that will select cross dimensions is cut intercepting; Second step: the groove of on the relative two sides, middle part of the rectangular steel pipe of the intercepting of fixed length, opening certain size; The 3rd step: expanding and shaping, utilize former and equip the position integral body of will slotting to expand into needed shape and size; The 4th step:, make the moulding position for circular at the trigonum at moulding position welding set square; The 5th step: fine limit work is carried out at the moulding position according to the required size of retarder is installed.
Claims (2)
1, a kind of new automobile driving axle housing is characterized in that: be to be processed by the steel pipe integral that a section is a rectangle.
