Manufacture field.
Background technology
The heat treatment deformation of bearing ring is the biggest on product quality impact, although can be revised by Technology for Heating Processing, but
Shaping technique is also one of effective measures controlling deformation.SG13Cr4Mo4Ni4V steel bearings ferrule arrangement is complicated, wall
Thickness changes greatly, and the temper of quenching after lasso carburizing all completes in vacuum air-quenching furnace, and quenching temperature is up to 1090
About DEG C, quenching cooling uses high pressure nitrogen air quenching method, is difficult to mold or mould control deformation technology in quenching process,
Lasso shaping can only be turned by martensite transfor mation in drawing process and retained austenite by the orthopedic or setting process before tempering
Become, reach the shaping purpose of lasso.
" rod hits " shaping and two processes of " forcing press " shaping are gone through in lasso shaping, but shaping effect is the most undesirable, exists
Many technical problems, are embodied in: the first, " rod hits " shaping relies primarily on artificial hammer force,
SG13Cr4Mo4Ni4V hardness of steel height deformation difficulty, the product that wall thickness and deflection are bigger is difficult to obtain reason by hammering shaping
The shaping effect thought, and hammer force and the change of hammer point, be easily caused the deformation of lasso non-ellipse, make shaping to continue；
The second, " forcing press " shaping Stroke Control is forbidden, and a lasso needs repeated multiple times measurement, shaping, could be preliminary
Reaching shaping purpose, equally exist the lasso non-ovalizing deflection rule that repeatedly pressure shaping causes, the shaping of a heat lasso needs
Experience 3～4 hours, it is impossible to the requirement carrying out being tempered in meeting quenching latter 2.5 hours.

The invention has the beneficial effects as follows: 1, invention applies bearing ring shaping equipment and technology, solve structure complicated,
A shaping technique difficult problem for lasso deformation in wall thickness change larger axis bearing ring vacuum heat treatment process,
Having lasting using value in SG13Cr4Mo4Ni4V steel ring vacuum carburization and heat treating trimming, this shaping is equipped
M50 steel, GCr15 steel ring shaping in, there is same application and promotional value；2, the present invention is used for structure
Bearing ring shaping equipment that complicated, wall thickness change is bigger and technology, mold in order to solving to be difficult in quenching process or
Mould controls the problem of deformation technology, and lasso shaping can only be by the orthopedic or setting process before tempering, by drawing process
Martensite transfor mation and Transformation of Retained Austenite, reach the shaping purpose of lasso；3, ovalizing deflection and diastrophic shaping,
All can realize the precisely shaping in advance of regularity on device of the present invention；4, during the present invention possesses reforming process, pressure becomes
The direct-reading of shape amount measures function, can apply suitable amount of over-pressurization according to lasso deflection size, offsets elastic deformation to shaping
The impact of effect；5, in drawing process, there is a certain amount of change of lasso after " resilience ", i.e. Stress Release after lasso shaping
Shape is recovered, and can effectively apply certain " overvoltage " by the present invention and measure, offset the impact that " resilience " deforms, it is thus achieved that reason
The shaping effect thought；6, the present invention carries out lasso shaping operation simplicity, safety, is guaranteed the rule of shaping by direct-reading measurement
Rule property controls, and shaping efficiency is high, meets the shaping needs of technique and product.
