Abstract

The utility model relates to a punching and welding axle housing consisting of a front cover and a back cover, which is characterized in that the front cover is provided with a reducer mounting hole and is directly connected with a set square, the back cover is directly connected with a final drive rear cover. The front cover and back cover of the utility model are formed by punching steel plate, and the front cover is welded with the back cover to be a whole; the axle housing saves the manufacturing and welding procedure of rear cover and set square, with less working procedure and low cost. The set square and front cover are formed from a whole, and the rear cover and back cover are formed from a whole, which results the high intensity of axle housing. The utility model is suitable for mass production and of high productive effect.

Description

The novel weldering axle housing that dashes

Technical field

The utility model belongs to the Manufacturing Technology for Automotive Parts field, particularly a kind of novel weldering axle housing that dashes.

Background technology

At present automobile dash the weldering axle housing adopt sheet metal forming be about two and half shells, deburring then, to being welded into whole shell.This axle housing is the axle housing that extensively adopts now.Such axle housing needs welding set square and bonnet before and after axle housing.As adopt the reinforced blank processing axle housing in both sides can save set square, but waste material, and bring difficulty to forming technology.Therefore at present quantity-produced is the axle housing that needs welding set square and bonnet.

Along with developing of automobile industry, the steel axle housing arises at the historic moment, and press welding axle housing is used for the production of axle housing in a large number.The axle housing cost of producing is low, the efficient height.Light-duty Vehicle, in-between car, heavy goods vehicles adopt in a large number at present.Little by little replaced casting bridge shell.But the shortcoming of dashing the weldering axle housing in use also comes out gradually.Dash the weldering axle housing easily at commissure fracture or cracking.Usually become the formation of crack of cracking at set square and bonnet weld, at bonnet and axle housing weld.Cause the appearance of problems such as intensity difference, leakage of oil.

Summary of the invention

The purpose of this utility model is exactly the deficiency at above-mentioned axle housing, has designed a kind of novel weldering axle housing that dashes.

The technical solution of the utility model is achieved in that

The novel weldering axle housing that dashes, axle housing is made up of preceding half shell, later half shell, it is characterized by: have the retarder mounting hole above preceding half shell, directly comprise set square on preceding half shell, directly comprise the axle housing bonnet on the later half shell.

The utility model adopts preceding half shell of steel plate drawing, later half shell, again the two halves shell is welded into whole shell, and this axle housing has saved the manufacturing and the welding sequence of bonnet and set square, and Fabrication procedure is few, and cost is low.Set square and preceding half shell are integrally formed, and bonnet and later half shell are integrally formed, axle housing intensity height.The utility model is fit to produce the production efficiency height in enormous quantities.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Specific embodiments

Describe concrete technical scheme of the present utility model in detail below in conjunction with accompanying drawing.

The novel weldering axle housing that dashes, axle housing is made up of preceding half shell 1, later half shell 2, it is characterized by: have the retarder mounting hole above preceding half shell, directly comprise set square on preceding half shell, directly comprise axle housing bonnet 4 on the later half shell 2.

As shown in Figure 1: the two halves shell was welded before and after axle housing adopted, and above preceding half shell retarder mounting hole was arranged, with set square be an one-piece parts, do not need to weld again, later half shell and axle housing bonnet belong to a part, disposable shaping, axle housing have only twice weld seam 3 up and down.

Concrete processing technology is as follows:

(1) blanking: following two sheet stocks, a slice preceding half shell 1 of axle housing, a slice later half shell 2 of axle housing that is used to be shaped that is used to be shaped;

(2) preceding half shell 1,2 drawings of later half shell: utilize compression machine preceding half shell 1 of drawing, later half shell 2 respectively, preceding half shell 1 is towards the retarder mounting hole.

(3) preceding half shell 1, later half shell 2 processing bevel for weldings;

(4) preceding half shell 1, later half shell 2 are welded into whole shell.

Claims (2)

1, the novel weldering axle housing that dashes, axle housing is made up of preceding half shell, later half shell, it is characterized by: have the retarder mounting hole above preceding half shell (1), directly comprise set square on preceding half shell (1), directly comprise axle housing bonnet (4) on the later half shell (2).

2, the novel weldering axle housing that dashes according to claim 1, it is characterized by: described preceding half shell (1), later half shell have bevel for welding on (2).
