Description
Technical field
The utility model relates to auto-parts technical field, specifically a kind of lining.
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, such part is low strength on the one hand, 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 lining that a kind of structure is simple, intensity is high in order to provide, stock utilization is high.
The utility model is achieved through the following technical solutions:
A kind of lining, comprise body, described body is made up of the cylinder that two sections of diameters are different, the outer side wall arc-shaped transition of described two cylinders connects, described body is provided with three the first through holes coaxially arranged in the axial direction, second through hole and third through-hole, described second through-hole diameter is less than the first through hole, described first through-hole diameter is less than third through-hole, described body upper-end surface is provided with around described first through hole the forged teeth that a circle is divergent shape, described body upper-end surface is positioned at outside described forged teeth and is provided with a circle groove, described second through hole and the described third through-hole place of connecting are provided with the first chamfering, the scope of the angle [alpha] between described first chamfering and axis is 10 ° ~ 20 °, described body lower end surface is provided with the second chamfering around described third through-hole, angle beta between described second chamfering and axis is 10 ° ~ 20 °.
Described second through hole and the described third through-hole place of connecting are provided with the first chamfering, and the angle [alpha] between described first chamfering and axis is 15 °.
Described body lower end surface is provided with the second chamfering around described third through-hole, and the angle beta between described second chamfering and axis is 15 °.
Two end faces of the outer side wall of described body, described body and described forged teeth are all processed by the mode of forging.
The madial wall of described first through hole and third through-hole is formed by machining.
The beneficial effect that the utility model brings is:
In the utility model, described lining has the following advantages: the method adopting forging, the surface area of part more than 80% is made to be all forging plane, improve the intensity of part, and then extend the working life of part, and the mode of forging machining can save material relatively, and then reduces cost of parts, improves the economic benefit of enterprise.
