Abstract
The present invention relates to the processing technique of a kind of bush of swing arm, comprise the following steps: gluing, assemble and vulcanize；The present invention uses, before sulfuration, the outer nylon tube of lining is pressed into swing arm endoporus, utilizes the outer nylon tube under the contractility of nylon part, room temperature to be not easily broken when assembling, eliminates the phenomenon of scrapping caused because outer nylon tube is damaged, improve conforming product rate；In the sulfidation in later stage, outer nylon tube is heated and swells, and the external diameter of both ends of the surface, under die pressure, increases release power, promotes the fitness of lining and swing arm, and then improves product quality.
Description
Technical field
The present invention relates to Automotive Steering Technology field, particularly relate to the processing technique of a kind of bush of swing arm.
Background technology
Along with the development of auto industry, people are more and more higher in the demand of the aspects such as energy-saving and environmental protection, comfortable, reliability to automobile.Steering-wheel flutter is the principal vibration phenomenon in car control mechanism, and this not only can affect the comfortableness of automobile, can also have certain impact to control stability simultaneously.Rubber bushing is as the elastic connection means of damping vibration, and Main Function is to absorb vibrational energy, and it is widely used at engine bearer, steering system and suspension rod hinge.Rubber bushing is good with its anti-vibration performance, has the advantage such as elastic characteristic and attenuation characteristic, it has also become critical elements indispensable on automobile.Therefore rubber bushing is closely related with the life of current people, simultaneously because rubber bushing belongs to, and parts are easily lost, and its market demand sustainable growth.
Existing bush of swing arm is constituted entirety by outer the sulfuration between nylon tube, rubber bushing, lining inner metal tube of lining.Outer nylon tube is press-fitted in swing arm endoporus after first vulcanizing again.Owing to the contractility of outer nylon tube is big, during sulfuration, temperature is high, and after product vulcanizes out, outside dimension slightly swells, and increases difficulty to being pressed into swing arm endoporus below.In process of press in, owing to nylon part size swells, nylon part is easily broken, and causes product rejection rate high.Additionally, existing technology nylon part two ends size is less, successfully press-in swing arm endoporus pusher is exerted oneself less.
Summary of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is that providing a kind of reduces nylon tube damage outer to lining, increases the production technology that product releases the bush of swing arm of power.
The present invention solves the technical scheme that above-mentioned technical problem used: the processing technique of a kind of bush of swing arm, comprises the following steps:
The processing technique of a kind of bush of swing arm, it is characterised in that comprise the following steps:
A, gluing: the piece surface adhesive coating that gluing is handled well at epithelium, make rubber can be sticked together with inner metal tube and outer nylon tube；
B, assembling: by outer nylon tube press-in swing arm endoporus；
C, sulfuration: the inner and outer pipe coating adhesive is put into mould, rubber is injected in mould by gum-injecting port, is full of die cavity, and under the effect of hot pressing, sulfuration completely, makes rubber and inner metal tube and outer nylon tube bond together.
Further, in step c, the outer nylon tube external diameter after described sulfuration is expanded.
Compared with prior art, it is an advantage of the current invention that: the present invention uses, before sulfuration, the outer nylon tube of lining is pressed into swing arm endoporus, utilize the contractility of nylon part, outer nylon tube under room temperature is not easily broken when assembling, eliminate the phenomenon of scrapping caused because outer nylon tube is damaged, improve conforming product rate；In the sulfidation in later stage, outer nylon tube is heated and swells, and the external diameter of both ends of the surface, under die pressure, increases release power, promotes the fitness of lining and swing arm, and then improves product quality.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention is embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Preferred embodiment, the processing technique of a kind of bush of swing arm, comprise the following steps: the piece surface adhesive coating that gluing is handled well at epithelium, make rubber can be sticked together with inner metal tube and outer nylon tube；By the outer nylon tube of room temperature state is pressed in swing arm endoporus；The inner and outer pipe coating adhesive is put into mould, rubber is injected in mould by gum-injecting port, is full of die cavity, and under the effect of hot pressing, sulfuration is completely, making rubber and inner metal tube and outer nylon tube bond together, the outer nylon tube external diameter after described sulfuration protrudes from swing arm inner port edge.
Compared with prior art, it is an advantage of the current invention that: the present invention uses, before sulfuration, the outer nylon tube of lining is pressed into swing arm endoporus, utilize the contractility of nylon part, outer nylon tube under room temperature is not easily broken when assembling, eliminate the phenomenon of scrapping caused because outer nylon tube is damaged, improve conforming product rate；In the sulfidation in later stage, outer nylon tube is heated and swells, and the external diameter of both ends of the surface, under die pressure, increases release power, promotes the fitness of lining and swing arm, and then improves product quality.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those of skill in the art that the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is replaced on an equal basis；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
Claims (2)
