Abstract
The invention provides a novel rubber bushing and a preparation method thereof, and relates to the technical field of rubber bushing processing. The novel rubber bushing comprises an inner framework, a middle framework and a rubber sleeve. The middle framework is arranged outside the inner framework in a sleeving mode, and the rubber sleeve is arranged outside the middle framework in a sleeving mode. One or more semicircular grooves are formed in the middle of the outer side of the inner framework, and semicircular bosses matched with the semicircular grooves are arranged at the positions, corresponding to the semicircular grooves in the inner framework, of the inner side of the middle framework. The inner framework is made of 45# steel, the middle framework is made of PA6.12, and the rubber sleeve is made of rubber NR. The inner framework, the middle framework and the rubber sleeve are produced respectively, and the inner side of the middle portion of the middle framework produced at the moment is not provided with the semicircular bosses; surface processing is carried out; assembling is carried out; adhesives are sprayed on the outer surface of the middle framework; sulfuration is carried out; and after-treatment is carried out. According to the novel rubber bushing and the preparation method thereof, friction and interference magnitude is reduced, and the degree of adaptability is improved; meanwhile, the phenomena of pressing damage of the inner framework and the middle framework in assembling and gaps between the frameworks after assembling are avoided, and the yield and production efficiency are improved.
Description
Technical field:
Invention relates to rubber bushing processing technique field, specifically a kind of new type rubber lining and preparation method thereof.
Background technique:
After existing rubber bushing product is assembled with inner frame by skeleton in plastics together with rubber sulfidization molding, in plastics, skeleton (PA6.12) endoporus contains two semicircular boss, before sulfuration, inner frame and middle skeleton carry out in assembly process, inner frame (45#) is easily by two semicircle boss crushings in the middle of middle skeleton (PA6.12) endoporus, skeleton is caused to scrap, up-to-standard rate reduces, and manufacturing efficiency is lower, cost increase.After having assembled, the phenomenon in gap between inner frame and middle skeleton, can be there is, have impact on the usability of product, reduce the satisfaction of client.
Summary of the invention:
The technical problem that invention will solve be to provide one avoid inner frame and middle skeleton simultaneously containing frictional force during boss and magnitude of interference excessive, be equipped with the bad phenomenon that there is gap of degree of adaptability between crushing, assembling back skeleton, improve new type rubber lining of up-to-standard rate and manufacturing efficiency and preparation method thereof.
Solve technical problem adopt following technological scheme:
A kind of new type rubber lining, it is characterized in that: comprise inner frame, middle skeleton and rubber sleeve, described middle skeleton is set on the outside of inner frame, described rubber sleeve is set on the outside of middle skeleton, the outer middle side part of described inner frame is provided with more than one semi-circular recesses, and the position of corresponding first the round groove of inner frame in inner side of described middle skeleton is provided with the semicircle boss coordinated with semi-circular recesses;
The material of described inner frame is 45# steel, and the material of described middle skeleton is PA6.12, and the material of described rubber sleeve is rubber NR.
A preparation method for new type rubber lining, is characterized in that: comprise the following steps successively,
(1) produce inner frame, middle skeleton and rubber sleeve respectively, in the middle part of the middle skeleton now produced, outside does not have semicircular boss;
(2) inner frame and middle skeleton surface treatment;
(3) inner frame and middle skeleton and rubber sleeve assemble;
(4) skeleton outer surface spraying binder in;
(5) sulfuration;
(6) later stage carries out deflashing and inspection.
Described NR is natural rubber.
Invention avoids there is crushing phenomenon in middle skeleton and inner frame assembly process, middle two semicircle boss forming methods inside skeleton in change, not containing semicircle boss before middle Skeleton assembly, middle skeleton and inner frame assembling: inner frame and middle skeleton (not containing boss) directly assemble, matching gap reduces, improve assembly qualified rate, two semicircle boss forming methods in the middle of middle skeleton endoporus, not ensured by plastic skeleton mould, but in sulfidation, be subject to the squeeze pressure transmitting injection rubber, with inner frame and shaping.
The beneficial effect of the invention is: invention friction and magnitude of interference reduce, degree of adaptability improves, reduce Design of Dies, Mould Machining complexity, reduce the processing cost of mould, avoid inner frame and middle Skeleton assembly simultaneously and have the phenomenon that there is gap between crushing, assembling back skeleton, improve up-to-standard rate and manufacturing efficiency.
Accompanying drawing illustrates:
Fig. 1 is the rubber bush structure schematic diagram of invention.
Fig. 2 be invention for assembling before middle skeletal structure schematic diagram.
Embodiment:
The technological means realized to make invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth invention further.
As illustrated in fig. 1 and 2, a kind of new type rubber lining, comprise inner frame 1, middle skeleton 2 and rubber sleeve 3, middle skeleton 2 is set on the outside of inner frame 1, rubber sleeve 3 is set on the outside of middle skeleton 2, the outer middle side part of inner frame 1 is provided with more than one semi-circular recesses 4, and the position of corresponding first the round groove 4 of inner frame 1 in inner side of middle skeleton 2 is provided with the semicircle boss 5 coordinated with semi-circular recesses 4;
The material of inner frame 1 is 45# steel, and the material of middle skeleton 2 is PA6.12, and the material of rubber sleeve 3 is rubber NR.
A preparation method for new type rubber lining, comprises the following steps successively,
(1) produce inner frame 1, middle skeleton 2 and rubber sleeve 3 respectively, in the middle part of the middle skeleton 2 now produced, outside does not have semicircle boss 5;
(2) inner frame 1 and middle skeleton 2 surface treatment;
(3) inner frame 1, middle skeleton 2 and rubber sleeve 3 assemble;
(4) skeleton 2 outer surface spraying binder in;
(5) sulfuration;
(6) later stage carries out deflashing and inspection.
NR is natural rubber.
More than show and describe the basic principle of invention and the advantage of major character and invention.The technician of the industry should understand; invention is not restricted to the described embodiments; the principle that invention is just described described in above-described embodiment and specification; under the prerequisite not departing from invention spirit and scope; invention also has various changes and modifications, and these changes and improvements all fall within the scope of claimed invention.Invent claimed scope to be defined by appending claims and equivalent thereof.
