Description
Technical field
The present invention relates to amortisseur field, specifically, be related specifically to the manufacture work playing drum cylinder barrel of a kind of amortisseur
Skill.
Background technology
Amortisseur shifts near vehicle body at automotive wheel, amortisseur by compression time, now amortisseur inner carrier moves down.Piston
The volume reducing of lower chambers, oil pressure raises, and fluid flows to the chamber (epicoele) of piston upper through playing drum passage.Epicoele is by piston rod
Accounted for a part of space, thus the volume that epicoele increases is less than the volume that cavity of resorption reduces, and a part of fluid the most just pushes pressure open
Contracting valve, flows back to oil storage cylinder.Oil is saved and is formed the damping force that suspension moves by compression by these valves.Amortisseur at wheel away from car
Body, amortisseur Tensile, at this moment the piston of amortisseur moves up.Piston upper chamber oil pressure raises, and flowing valve is closed, upper intracavity
Fluid is pushed rebound valve open and is flowed into cavity of resorption.Due to the existence of piston rod, the fluid come from epicoele stream is not enough to be full of what cavity of resorption increased
Volume, instigator's cavity of resorption produces a vacuum, and at this moment the fluid in oil storage cylinder is pushed recuperation valve open and flow to cavity of resorption and supplement.Due to this
The throttling action of a little valves, therefore plays damping action to when being suspended in and do stretching exercise.
Two-way double acting telescopic shock absorber requires that working cylinder outer surface has carried out drum, makes internal owing to obtaining in motor process
To effective cushioning effect, can effectively filter vibrations, even the road surface of muddy frustration, it is also possible to allow driver enjoy easypro
Suitable sense.
The manufacturing process program of existing two-way double acting telescopic shock absorber is complicated, and the amortisseur precision manufactured is not
Foot, affects subsequent use.
Summary of the invention
Present invention aims to deficiency of the prior art, it is provided that the manufacture work playing drum cylinder barrel of a kind of amortisseur
Skill, uses the drum cylinder barrel that this technique manufactures, and after applying to amortisseur, its cylinder barrel is had in motor process with piston
The cushioning effect of effect, is greatly reduced vibration amplitude.
Technical problem solved by the invention can realize by the following technical solutions:
The manufacturing process playing drum cylinder barrel of a kind of amortisseur, comprises the steps:
1) selection cold-rolled steel sheet is as raw material, and its longitudinal shear is become bar；
2) cold-rolled steel sheet cutting into bar is welded as welded tube by high-frequency induction welding technique；
3) described welded tube is put into room temperature degreasing bath, carry out washing and water-soluble anti-rust；
4) described welded tube being carried out bright annealing process, annealing temperature is 690-720 DEG C, and the welded tube temperature after annealing exists
50-100℃。
5) welded tube after annealing is carried out surface lubrication process；
6) use PD external mold to coordinate after the most extruded to the external diameter of welded tube, internal diameter with mould in AP, then carry out secondary connection
Pull out processing；
7) welded tube after connection being pulled out processing is aligned, it is ensured that linearity is less than 0.15/500mm；
8) carry out cutting off and two ends chamfered by the welded tube after aligning；
9) welded tube after being disposed is carried out totally with bearing 0.02mm drift with internal diameter lower limit, then Welded Pipe inner surface enters
The full inspection of row；
10) play drum to process:
A, indoor design rubber king play bulging mould, and mould includes external mold, base and pressure bar；
B, equipment use 100T oil pressure forcing press；
C, material use tendon Bovis seu Bubali rubber bar external diameter ￠ 34.8mm, length 60mm；
Concrete operation step is as follows: first rubber king's external mold and base is fixed on 100T press device, is put into by welded tube
Again rubber king rod and pressure bar are put into welded tube in mould, start press device by pressure bar toward being pushed down into 10 ± 0.5mm, then will
Pressure bar, rubber king and steel pipe take out, and play drum cylinder barrel and machine；
12) finished product inspection: checking, according to drawing requirement, the size playing drum cylinder barrel, inner surface is examined entirely, interior
Can not there be any scuffing on surface.
Further, described step 2) in high-frequency induction welding technique comprise the steps:
Inside and outside burr → cooling → the eddy current of feeding → thick molding → high-frequency welding → removal of shearing butt welding → storing → welded tube
Flaw detection → welded tube precisive shaped → fixed ruler cutting → removal inner burr → finished product inspection.
Further, described step 5) in surface lubrication process technique comprise the steps: pickling → washing 2 times → in
With → washing → dry → pinching → lubrication.
Compared with prior art, beneficial effects of the present invention is as follows:
The amortisseur cylinder barrel using technique manufacture of the present invention plays drum, uses mechanical type at the inside same position of steel pipe
Bloat three bulges, simultaneously need to ensure that inside dimension not can exceed that the positive and negative 0.02mm requirement of original id tolerance, due to gold
Belong to while playing drum expansion, will result in internal diameter size contraction, cause follow-up piston to pass through.This has developed drum mould
Use rubber king to carry out extruding expansion processing and effectively ensure that inside dimension requirement.
