Description
Technical field：
The utility model is related to a kind of heat-treatment quenching molds, quench more particularly to a kind of combination of dimension adjustable formula precision
Fiery mold.
Background technology：
At present, in the range of machine-building processing industry, in order to improve production efficiency, reaching reduces production cost target, institute
There is the roller system bearing needed for large-scale metallurgical rolling equipment to select four-line column roller bearing and four-row tapered roller bearing（It is commonly called as
Rolling mill bearing）, to meet the specific operation of shock resistance, heavy load.And the accuracy of manufacture of rolling mill bearing and the length of service life,
The production efficiency and benefit of large-scale pressworking equipment will be directly affected, therefore rolling mill bearing material has selected the high-quality carburizing steel to be
It is main.In order to make rolling mill bearing stable quality that must make rolling mill bearing working surface and internal acquisition uniform and delicate sclerotic tissue, then
It is required that the deflection of bearing ring must be controlled in production heat treatment carburizing and quenching process（The smaller bearing carburizing heat treatment of deflection
Quality is higher, and service life is higher）, mould must be used in the part heat treatment process for this to bearing need to be quenched
Tool, to control the size of part and deflection.At present rolling mill bearing manufacturer put into great effort give research want change mesh
It is preceding using fixing mould when caused Production of bearing cost is excessively high, the period is long, labor intensity is big, efficiency is low production, technology
Bottleneck.Years of researches pass through in our companies, have devised a kind of novel size adjustable precision combination quenching mould structure, solution
It has determined the above problem and shortcoming easily occurred when being quenched using traditional moulds；Efficiency can be greatly improved, reduces labor intensity, surely
Fixed output quota quality, further can reach reduces cost and consumption, increases the performance of enterprises.
The research of accurate combination quenching mould is tried size adjustable it may first have to heat treatment quenching process feature is caught,
The process characteristic is：Quenching workpiece it is high temperatures（800-900°C）, the activity duration is short instantaneous（30-90 seconds）；That is high temperature workpiece goes out
Quickly mold is mounted in workpiece after stove, and be put into quenching medium and cool down（Time is less than 90 seconds）, novel size
Adjustable precision combination quenching mould design structure must be simplified, is easy to install, is quick detachable.And traditional fixing mould design is excellent
Point is to be conducive to material harmomegathus attribute and catch and be heat-treated instantaneous process characteristic, though structure is simple easy to install, shortcoming is dismounting
It is difficult.I.e. the die feature is to use to touch on the whole to be packed into workpiece simultaneously from workpiece both ends of the surface respectively with whole lower die, the work
Skill is commonly used for a long time in bearing industry with tooling.The extension required with user bearing service life（It is same with international top-brand
Service life）, we carry out thoroughgoing and painstaking research and find the following deficiency that this kind of tooling will appear in mold using process：1st, because being somebody's turn to do
Mold only controls workpiece both ends, and workpiece height size the recessed heart easily occurs compared with position between Gao Shi senior middle schools（Mold is not in contact with place's size contracting
It is small）.2nd, workpiece contraction causes because matching allowance is excessive between mold and workpiece, then mold to be caused to be difficult to dismantle, very after quenching
To using mechanical means sometimes from can not fall the mould release in workpiece, it is necessary to using forcing machine-tooled method by mold turning
Remove and cause to scrap（Cost is very high, the production cycle extends）, the production schedule is made to be difficult to be smoothed out.And the accurate group of size adjustable examination
It is exactly to preferably solve the above problem occurred in production process to close quenching mould research and development, that is, improves efficiency, reduces labour
Intensity, conducive to organization of production.After being summarized at present by production process repetition test early period, on the basis of raising is continuously improved,
It has been achieved with and has accumulated certain achievement and experience.Further work by the achievement systematization, scale, be enterprise and society
Create more Multi benefit.

The utility model is designed reasonably can improve efficiency, reduce labor intensity, stabilized product quality.In our company Re Chu
Reason subsidiary factory promotes the use of, and the data measured after now being compared with conventional fixed-type quenching mould (old mold) are summarized as follows:1st, pacify
It is compared in terms of dress, dismounting mold；Two kinds of mold times of installation are essentially identical, no more than 1 minute；Dimension adjustable formula precision group
It closes quenching mould and has the take-down time within 1 minute, and old mold needs 30~60 minutes, comparison working efficiency promotes minimum 15
Times.2nd, labor intensity is put into：Using dimension adjustable formula precision, combination 3 people operating personnel of quenching mould can operate continuously（Behaviour
Author is referred to as a hammer and is sized）；And fixed mold is used to need 8 people's alternate operations（Swing sledgehammer）Or even also occur that mold
It is dismantled to get off from workpiece（Only mold turning is destroyed）.3rd, to processing quality：It is combined using dimension adjustable formula precision
Quenching mould, which processes Roundness of Workpiece, can control 0.2~0.5mm, using fixed mold workpieces processing circularity precision 0.5~
2.0 mm, 4 times of Quality advance.Need to grind processed diameter of work size surplus with dimension adjustable formula precision combination quenching mould is
0.5~1.2 mm, it is 1.5~3.0mm that need to grind processing diameter dimension surplus with fixing mould, and processing efficiency improves 1 times or more.4、
In terms of quality stability：If quench first workpiece test size, precision with dimension adjustable formula precision combination quenching mould
Technological requirement is not met, axial adjusting device can be adjusted in technological requirement size in 1 minute；It is quenched with fixing mould
Workpiece will appear two kinds of spies and remove situation,（1）, mould release be stranded when need to cause to give birth to other unit repairing mould fit dimensions
Production is interrupted.（2）, die workpiece fit clearance it is big（It is quick detachable）, cause institute's quenching workpiece off quality, because of mold outer diameter
It is small, need to put into again the Mold Making time most it is short need 15 days with Production of bearing cycle stretch-out（Or it is forced to interrupt）.200KW electricity
Frequency glowing furnace needs 6 hour heatings to can be only achieved to hardened area temperature（More than 800 °C）, but because mold reason is forced blowing out,
Energy waste will be caused serious.5th, size range：It can be with a set of dimension adjustable formula precision combination quenching mould quenching size
100mm ranges adjust, and can substitute fixed 20 sets of mould of quenching, highly beneficial to production link.
The above descriptions are merely preferred embodiments of the present invention, not makees limit in any form to the present invention
System, any simple modification, equivalent change and modification that every technical spirit according to the present invention makees the example implemented above,
In the range of still falling within technical solution of the present invention.
