Abstract
The invention discloses a kind of bearing ring Q-tempering deformation amount controlling method, comprise Quench and temper process, before heating bearing housing blank grinding tolerance is controlled in 0.15mm, the bearing housing blank material often criticizing heating controls at 100kg-200kg, bearing housing blank material is divided and is deposited in process furnace, heap height is in 300mm, Heating temperature is 820-860 DEG C, be incubated after 40-50 minute, cooled by oil cooling, oil temperature is 30-80 DEG C, and cooling post-heating is to 160-200 DEG C, insulation 2.5-3 hour, last naturally cooling.Instant invention overcomes the deficiencies in the prior art, by controlling blank grinding tolerance, often criticize quantity and the stacking mode of heated mandrel bearing ring, pass through the meticulous control temperature time again, make bearing ring Q-tempering deflection can control in the minimum tolerance of national standard deflection once, decrease stock removal and grinding difficulty, enhance productivity, ensure quality product, reduce material and energy consumption.
Description
Technical field
The present invention relates to Q-tempering technical field, specifically belong to a kind of bearing ring Q-tempering deformation amount controlling method.
Background technology
The material of bearing ring is bearing steel, because bearing steel material reason thermal treatment after strain amount own is larger, the bearing ring that heat treatment deformation amount is larger can cause a series of adverse consequences in Grinding Process, such as: consume emery wheel unevenly and strengthen with local mill amount the localized burn causing stone surface distortion and workpiece, crushing then can cause the waste of abrasive material and the consumption of non-cutting time too frequently; In addition, serious distortion workpiece even can cause making processing to carry out because not having grinding tolerance, finally occurs waste product.Therefore, the Q-tempering deflection of Control Shaft bearing ring is significant for quality product of enhancing productivity, ensure, reduction material and energy consumption.
Summary of the invention
The object of this invention is to provide a kind of bearing ring Q-tempering deformation amount controlling method, overcome the deficiencies in the prior art, project organization is reasonable, before heating bearing housing blank grinding tolerance is controlled in 0.15mm, the bearing housing blank material often criticizing heating controls at 100kg-200kg, bearing housing blank material is divided and is deposited in process furnace, heap height is in 300mm, Heating temperature is 820-860 DEG C, is incubated after 40-50 minute, is cooled by oil cooling, oil temperature is 30-80 DEG C, cooling post-heating, to 160-200 DEG C, is incubated 2.5-3 hour, last naturally cooling.
The technical solution used in the present invention is as follows:
A kind of bearing ring Q-tempering deformation amount controlling method, comprises Quench and temper process, controls in 0.15mm before heating by bearing housing blank grinding tolerance, the bearing housing blank material often criticizing heating controls at 100kg-200kg, bearing housing blank material is divided and is deposited in process furnace, and heap height is in 300mm, and Heating temperature is 820-860 DEG C, be incubated after 40-50 minute, cooled by oil cooling, oil temperature is 30-80 DEG C, and cooling post-heating is to 160-200 DEG C, insulation 2.5-3 hour, last naturally cooling.
The blank material preferably often criticizing heating controls at 150kg, and bearing housing stacks 4-5 layer.
Preferred quenching temperature is 840 ± 5 DEG C.
Preferred tempering temperature is 180 ± 5 DEG C.
Compared with the prior art, beneficial effect of the present invention is as follows:
Bearing ring Q-tempering deformation amount controlling method of the present invention, by controlling blank grinding tolerance, often criticize quantity and the stacking mode of heated mandrel bearing ring, pass through the meticulous control temperature time again, make bearing ring Q-tempering deflection can control in the minimum tolerance of national standard deflection once, decrease stock removal and grinding difficulty, enhance productivity, ensure quality product, reduce material and energy consumption.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
