Description

Technical Field

[0001] The utility model relates to the field of cold-drawn tubes, in particular to a precision cold-drawn tube production line for a shock absorber piston rod. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

[0003] The piston rod is extremely important in the shock absorber. The quality of the piston rod determines the quality of the shock absorber. Most shock absorber piston rods are produced by cold drawing. In the common cold drawing production lines on the market, one end of the piston rod after cold drawing is separated from the mold when the other end receives tension, falls onto the lathe, and then rolls to one side. In this process, the surface of the piston rod will be damaged, affecting the quality of the piston rod. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] A motor is installed inside the base, a rotating shaft is fixedly connected to the output end of the motor, a gear is fixedly connected to the surface of the rotating shaft, and a chain is installed on the surface of the gear.

[0010] As a further description of the above technical solution:

[0018] The utility model has the following beneficial effects:

[0019] 1. Compared with the prior art, this precision cold-drawn tube production line for the shock absorber piston rod uses a support ring, a support plate, and a ramp. During use, when the upper and lower pressure plates clamp the piston rod and pull it to the right to a specified position, the left end of the piston rod leaves the mold and falls on the support plate installed on the upper surface of the base. At this time, the second cylinder extends, the piston rod is released, and the third cylinder fixed on the surface of the base extends to clamp the right end of the piston rod to fix the position of the piston rod.
