Description
Technical field
The utility model belongs to machining equipment field, relates to the compressible spacer enlarging of a kind of propons and bulging Combined machining mould.
Background technology
Drive the pretightning force of front axle differential gearbox master gear bearing very large to the performance impact of whole bridge.In general, two kinds are had to the assembling form of master gear bearing clearance adjustment: incompressible spacer and compressible spacer.Compressible spacer can from the pretightning force of Row sum-equal matrix bearing in certain scope, and bearing pre-fastening can be adjusted to optimum state, avoid bearing assemble tension, or pine generation axial float crossed by bearing, reduce main gearbox assembly noise, improve main gearbox assembly quality; Meanwhile, because it has compressibility, therefore can prevent main teeth nut from loosening; In addition, compressible spacer can also solve the trouble of gear-bearing equipment adjustment, reduces the number of times of examination shimming, reduces labour intensity, enhances productivity; It is the desirable product of alternative incompressible spacer.
The mode of production that the compressible spacer of this type of contour structures is traditional uses two dynamic four-column hydraulic press to produce, enlarging operation is not implemented after blanking procedure, direct bulging processes product, the mould structure used is complicated, complex operation step, produce length consuming time, key be due to the fierceness distortion of product blank single easily cause comparatively greatly its internal tiny crack even tube wall break and affect properties of product, therefore, there is risk in the quality of product always.
What the utility model existed based on production method in prior art just can optimization consider, design a kind of enlarging operation coordinates single work step formula structure mould with bulging operation multistation, product blank single deflection can be made little, compressible spacer is avoided to occur crackle and break, like this by design a kind of can meet produce compressible spacer enlarging, bulging multi-station mold, improve quality stability and the production efficiency of product, just seem very necessary.
Utility model content
The purpose of this utility model is the deficiency optimizing existing production method, adapts to reality need, provides the compressible spacer enlarging of a kind of propons and bulging Combined machining mould.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of compressible spacer enlarging of propons and bulging Combined machining mould, comprise cope match-plate pattern and lower bolster, the both sides bottom cope match-plate pattern are provided with enlarging upper holder block and bulging upper holder block, and the longitudinal section of described enlarging upper holder block and bulging upper holder block is all in inverted " recessed " font; The openend of bulging upper holder block is lower than the openend of enlarging upper holder block;
Lower bolster) both sides, inside be respectively equipped with enlarging punch and bulging punch, described enlarging punch and bulging punch are all in step straight tube shape;
Height limiter is provided with between cope match-plate pattern and lower bolster;
The mould column kit of topping bar of the openend of described enlarging upper holder block and shrinkage pool and enlarging punch forms the expanding station of compressible spacer under the effect of height limiter, and the mould column kit of topping bar of the openend of bulging upper holder block and shrinkage pool and bulging punch forms the bulging processing stations of compressible spacer under the effect of height limiter.
During synchronous processing, the shrinkage pool of enlarging upper holder block and the mould post matched in clearance of topping bar of enlarging punch are slidably connected; The shrinkage pool of bulging upper holder block and the mould post matched in clearance of topping bar of bulging punch are slidably connected; The maximum outside diameter size of enlarging punch and the enlarging part bottom inner diameter consistent size of compressible spacer, the maximum outside diameter size of bulging punch and the bulging part bottom inner diameter consistent size of compressible spacer.
Form the enlarging die cavity of compressible spacer between described enlarging upper holder block, enlarging punch and lower bolster, bulging upper holder block, between bulging punch and lower bolster, form the bulging die cavity of compressible spacer.
Height limiter is the two pieces limit for height block be located between described cope match-plate pattern and lower bolster, two pieces limit for height block is arranged on the forward and backward position of the bosom of lower bolster respectively, the difference in height of limit for height block and enlarging upper holder block is the total length after the enlarging of enlarging part, and the difference in height of limit for height block and bulging upper holder block is the total length after bulging part bulging.
Described lower bolster is connected with positioner and device for discharging respectively.
The beneficial effects of the utility model are:
1. that product blank can be made to be out of shape is little for the structure of enlarging operation of the present utility model and the independent discrete of bulging operation, product can be avoided to occur breaking because of the fierceness distortion of single, ensure that the face shaping light of compressible spacer is regular, strength character and pressure curve stablize;
2. product enlarging and bulging two procedures can be made to complete in an impulse stroke, thus promote productive temp, increasing production capacity, reduction production cost.
