Description
Technical field
The utility model relates to auto-parts technical field, specifically a kind of pipe.
Background technique
Component majority in the market on automobile is all formed by mach mode manufacture, particularly some columniform parts, all processed by numerical control machine tool, therefore there are several machining faces in part, similar length on market, long tube of analogous shape, its madial wall and outer side wall are not forging planes, such shortcoming is, pipe strength is relatively low, in addition, manufacture process effort is time-consuming, economic benefit is relatively low, situation about damaging easily is there is in the process of Long-Time Service, and then there is certain potential safety hazard, on the other hand in the process of forming parts, chip is needed to fall unnecessary material, therefore stock utilization is low, then the cost of part is relatively high.
Model utility content
The utility model pipe that a kind of structure is simple, intensity is high in order to provide, manufacturing efficiency is high.
The utility model is achieved through the following technical solutions:
A kind of pipe, comprise body, described body is cylindric, described body is provided with a manhole in the axial direction, described manhole runs through described body, the upper-end surface of described body is provided with a circle rib, described body upper-end surface is provided with a boss around described manhole, the diameter of described boss is less than the diameter of described rib, by the first circular arc chamfering between described body outer side wall and described rib, the upper end surface that described manhole is positioned at described body is provided with the second circular arc chamfering.
Described manhole is positioned at described body lower end surface place and is provided with the first plane chamfering.
The madial wall of the outer side wall of described body, the upper-end surface of described body and described body is all processed by the mode of forging.
The lower end surface of described body is formed by machining.
The beneficial effect that the utility model brings is:
In the utility model, described pipe has the following advantages: adopt repeatedly forging method, the madial wall of described body and outer side wall are all forging faces, improve the intensity of part, and then extend the working life of part, and the mode processing technology of forging is relatively simple, and then improves manufacturing efficiency, improves the economic benefit of enterprise; Described first circular arc chamfering and the second circular arc chamfering improve the intensity of body further; The design of described first plane chamfering facilitates the installation of pipe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the sectional drawing of pipe described in the utility model;
Fig. 2 is the plan view of pipe described in the utility model;
Fig. 3 is the partial enlarged drawing at A place in Fig. 3;
Fig. 4 is the partial enlarged drawing at B place in Fig. 3.
The label that in figure, component names is corresponding is as follows:
1, body; 2, manhole; 3, rib; 4, boss; 5, the first circular arc chamfering; 6, the second circular arc chamfering; 7, the first plane chamfering.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As the embodiment of pipe described in the utility model, as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, comprise body 1, described body 1 is in cylindric, described body 1 is provided with a manhole 2 in the axial direction, described manhole 2 runs through described body 1, the upper-end surface of described body 1 is provided with a circle rib 3, described body 1 upper-end surface is provided with a boss 4 around described manhole 2, the diameter of described boss 4 is less than the diameter of described rib 3, by the first circular arc chamfering 5 between described body 1 outer side wall and described rib 3, the upper end surface that described manhole 2 is positioned at described body 1 is provided with the second circular arc chamfering 6.
In the present embodiment, described manhole 2 is positioned at described body 1 lower end surface place and is provided with the first plane chamfering 7.
In the present embodiment, the madial wall of the outer side wall of described body 1, the upper-end surface of described body 1 and described body 1 is all processed by the mode of forging.
In the present embodiment, the lower end surface of described body 1 is formed by machining.
Claims (2)
