Abstract
The bicycle conjoined rear shock absorber casing is mainly formed by processing a steel pipe or an aluminum pipe through the working procedures of necking, flattening, punching, machining and the like, and is characterized in that the upper end of the casing is flattened and punched to manufacture the conjoined casing without a welding port.
Description
This practical association and a kind of bicycle rear shock absorber shell.
Produce now and go up the bicycle rear shock absorber shell of making, being welded of steel pipe system by steel sleeve and reducing steel pipe owing to there is the problem of dry joint, be loaded on bicycle after, the phenomenon that has weld bond to rupture during use; Forming with aluminium bar machinework or forging of aluminum, its productive costs is higher.
The purpose of this utility model is to propose a kind of bicycle disjunctor rear shock absorber shell, is used to prevent the fracture of bicycle rear shock absorber shell, and reduces production costs.
The purpose of this utility model is achieved in that utilizes press, reducing mould with steel pipe or aluminum pipe upper end reduced diameter, and utilize punch press with the upper end of reduced diameter towards flat, in towards flat upper end punching, promptly can be made into bicycle disjunctor rear shock absorber shell again; Owing to there is not weld bond, can prevent effectively that the problem of weld bond fracture from occurring, the saving in material that the bicycle rear shock absorber ratio that uses aluminum pipe to make is simultaneously made with aluminium bar.
Fig. 1 is a bicycle disjunctor rear shock absorber containment structure scheme drawing.
Below in conjunction with Fig. 1 the utility model is further set forth.
Bicycle disjunctor rear shock absorber shell shown in Figure 1, the round tube of steel pipe or aluminum pipe system (1) is used the press reducing with its upper end (2), with punch press towards flat, upper end (2) is an arc-shaped transition towards flat position and round tube (1) disjunctor position (3), towards flat its internal clearance of back (4) is 0.1~18mm, and (2) punching (5) in the upper end, the aperture is ¢ 12 ± 0.20mm, middle cylindrical processing thread (6) in round tube (1), circle processing thread (7) in the lower end of round tube, again the shell of steel pipe system is electroplated, the shell anodization of aluminum pipe system, thus the conjoined outer shell that does not have weld bond made.
So far, the utility model has been carried out comprehensive elaboration.
Claims (5)
1, bicycle disjunctor rear shock absorber shell, mainly by steel pipe or aluminum pipe through reducing, form towards flat, punching, machinework, the upper end (2) that it is characterized in that round tube (1) is flat, flat position, upper end (2) porose (5), and round tube (1) is the conjoined outer shell that does not have weld bond with upper end (2).
2, bicycle disjunctor rear shock absorber shell according to claim 1 is characterized in that upper end (2) is 0.1~18mm towards flat its internal clearance of back (4).
3, bicycle disjunctor rear shock absorber shell according to claim 1, the aperture that it is characterized in that hole (5) is ¢ 12 ± 0.20mm.
4, bicycle disjunctor rear shock absorber shell according to claim 1 is characterized in that upper end (2) is arc-shaped transition towards flat position and round tube (1) disjunctor position (3).
5, bicycle disjunctor rear shock absorber shell according to claim 1 is characterized in that round tube (1) is with steel pipe or aluminum pipe manufacturing.
