Description

Straightening machine for processing piston rod for air spring

Technical Field

The utility model relates to an air spring production facility technical field specifically is a straightener is used in processing of piston rod for air spring.

Background

A gas spring (gas spring) is an industrial accessory which can play the roles of supporting, buffering, braking, height adjusting, angle adjusting and the like. It is composed of the following parts: the device comprises a pressure cylinder, a piston rod, a piston, a sealing guide sleeve, a filler (inert gas or oil-gas mixture), an in-cylinder control element, an out-cylinder control element (a controllable gas spring), a joint and the like. The principle is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, the pressure in a cavity is several times or dozens of times higher than the atmospheric pressure, and the motion of a piston rod is realized by utilizing the pressure difference generated by the cross section area of the piston rod smaller than that of the piston. Due to the fundamental difference in principle, the gas spring has very remarkable advantages compared with the common spring: the speed is relatively slow, the dynamic force change is not large (generally within 1: 1.2), and the control is easy. The disadvantages are that the volume is relatively small without a helical spring, the cost is high and the service life is relatively short. Unlike mechanical springs, gas springs have a nearly linear spring curve. The elastic coefficient X of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions. The air spring is a lifting spring which can save labor, and can be divided into a self-locking air spring (such as the lifting of the bottom of a seat, the back of a boss chair and the like) and a non-self-locking air spring (such as the lifting support of a car trunk and a closet door).

The piston rod for the gas spring is made of metal, after the metal material is subjected to hot working, in the cooling process, the metal material can be subjected to shrinkage deformation to a certain degree due to cooling, and due to the fact that the metal material has larger length, the metal material can be subjected to shrinkage deformation to a certain degree at different positions, the metal material can be bent to a certain degree, and the piston rod can be directly used as a workpiece, so that the metal material and a connected object can not be accurately matched easily, the problems are caused to the processing of a product and the quality of the product, and the piston rod can be straightened in the manufacturing process of the piston rod of the gas spring.

Straightening machines, also called wire straightening machines, wire straightening and cutting machines, straightening and cutting machines. A straightening and wire-breaking machine belongs to straightening equipment. The straightening machine is one of reinforcing bar processing machinery. The steel bar straightening machine is used for straightening and cutting steel bars with the diameter of below 14 mm, and the cutting length can be customized according to the requirements of customers. Can be used for straightening and cutting stainless steel wires, aluminum wires, cold-drawn wires, plastic-coated steel wires and the like, and has the advantages of uniform cut, small error and good performance. The operation principle is as follows: the motor is driven by a belt to accelerate, so that the straightening barrel rotates at a high speed, the steel bars passing through the straightening barrel are straightened, and rust on the surfaces of the steel bars are removed by the straightening die; the motor drives the two conveying press rollers to pull the steel bars to move forwards through the other pair of speed reducing belts and the gear reduction box, and the crank wheel is driven to enable the hammer head to move up and down. When the reinforcing bar alignment reaches predetermined length, the tup hammering goes up the knife rest, cuts off the reinforcing bar, and when the reinforcing bar of cutting off fell into receiving the work or material rest, because the spring action, the sword platform got back to the normal position again, accomplished a circulation.

Because the design of the piston rod of air spring needs the higher cross sectional dimension of precision, small bending deformation all can the performance decline of piston rod, and the piston rod needs to possess higher rigidity and intensity, the alignment degree of difficulty is great after the cooling, and can't learn after the alignment whether cross sectional dimension is in error range, if continue processing and end use, can lead to air spring product quality unqualified, so can not adopt traditional straightener, in order to solve above-mentioned problem, the air spring piston rod processing of a novel structure has been designed here and has been used the straightener.
