Abstract
The utility model relates to a piston cylinder blank, particularly relates to a piston cylinder of a compressor hollow piston and aims at providing a piston cylinder of a high-silicon aluminum alloy hollow piston. The piston cylinder of the high-silicon aluminum alloy hollow piston is simple in structure, facilitates cold extrusion, can be molded through once cold extrusion, and is not easy to crack. The piston cylinder of the high-silicon aluminum alloy hollow piston comprises a circular bottom surface and a circular cylinder body which is arranged vertically upward along the circular bottom surface, a protruding shoulder is arranged on the circumference of the outer side wall of the circular cylinder body connected with the circular bottom surface, the outer diameter of the position wherein the circular bottom surface is connected with the circular cylinder body is larger than that of other positions of the cylinder body, and a clamp fixing body or positioning body for subsequent procedure processing is arranged at the center of the other surface of the circular bottom surface. The piston cylinder of the high-silicon aluminum alloy hollow piston has the advantages of being high in production efficiency, high in tensile strength, long in service life and the like.
Description
Technical field
The utility model relates to a kind of piston barrel blank, the especially piston barrel of compressor hollow piston.
Background technique
The hollow Piston Machining of present automobile air conditioner compressor piston, especially silumin all adopts forge hot to carry out, and is sawed-off as required, thereby heating forges the blank moulding, the hollow piston blank is divided into two parts, and a part is the piston seat blank, and another part is the piston barrel blank; Integrally welded after this two-part machine shaping.The power consumption of the processing mode of this blank, pollution is arranged, because use releasing agent during forge hot, volatilization pollutes the environment.Also some enterprise adopts cold forging also to claim the mode of cold-extruded processing, because the hollow piston material is silumin, so be difficult to adopt cold forging for silumin, meeting discrepitate in blank surface chaps during cold forging.This problem is anxious to be resolved.
The structure of the blank of described piston barrel is that the rounded bottom surface lateral margin is extended with sidewall to same direction and perpendicular to the bottom surface, and the another side center of described rounded bottom surface is provided with later process and adds man-hour anchor clamps and fix or process positioning body.The piston barrel of this structure shape and when adopting cold forging with the silumin material, the drum surface of formation can chap.This problem is anxious treats that we solve.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, make things convenient for cold-extruded and can once cold extrusion moulding be difficult for the piston barrel of the silumin hollow piston of be full of cracks.
The piston barrel of silumin hollow piston of the present utility model, it comprises a rounded bottom surface and along rounded bottom surface ring cylinder vertically upward, and with on the circumference of the ring cylinder outer side wall of rounded bottom surface connection convex shoulder is arranged, external diameter that namely should the place is greater than the external diameter at other place of cylindrical shell, and the center of the another side of described rounded bottom surface is provided with later process and adds anchor clamps fixed body or positioning body in man-hour.
As preferably, the joint of the convex shoulder of described piston barrel and other cylindrical shell outer side wall is by the arc shaped surface transition, and the wall thickness of this convex shoulder height and rounded bottom surface is close, and is preferably identical.
The piston barrel of this structure needs only according to the product specification corresponding mould when cold-extruded, the hollow piston barrel of once extruding by mould can not chap, certainly when cold-extruded, the silumin material will be under 400-600 ℃ of temperature 2-3 hour annealing in process, then be cooled to natural temperature with stove, again cold-extruded to the lathe.
It is high that the piston barrel of silumin hollow piston of the present utility model in sum has manufacturing efficiency, and tensile strength is large, the characteristics such as long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In Fig. 1, the piston barrel of silumin hollow piston of the present utility model, it comprises a rounded bottom surface 1 and along rounded bottom surface circular cylinder 2 vertically upward, and with on the circumference of circular cylinder 2 outer side walls of rounded bottom surface 1 connection convex shoulder 3 is arranged, external diameter that namely should the place is greater than the external diameter at other place of cylindrical shell, and the center of the another side of described rounded bottom surface 1 is provided with later process and adds anchor clamps fixed body or positioning body 4 in man-hour; The convex shoulder 3 of described piston barrel passes through the arc shaped surface transition with the joint of other cylindrical shell outer side wall, and these convex shoulder 3 thickness are identical with the wall thickness of rounded bottom surface 1.
