Abstract
The invention discloses a 42CrMo gear shaft heat treatment technology. The technology comprises 1, normalization: heating a normalization furnace to a temperature of 870-880 DEG C, carrying out thermal insulation for 1h and carrying out air cooling at a cooling rate of 20 DEG C/s, 2, hardening and tempering: heating a workpiece to a temperature of 840 DEG C, carrying out oil cooling quenching, keeping the temperature for 1h, putting the workpiece into a tempering furnace at a temperature of 480 DEG C, carrying out tempering, keeping the temperature for 1-1.5h and carrying out air cooling, 3, induction quenching: heating the workpiece to a temperature of 890-900 DEG C in an induction furnace, keeping the temperature for 35s and carrying out air cooling at a cooling rate of 65 DEG C/s, and 4, low temperature tempering: heating the workpiece to a temperature of 150-180 DEG C, keeping the temperature for 2.5h and carrying out air cooling at a cooling rate of 20 DEG C/s. The technology has simple processes and substantially improves performances of a treated gear.
Description
Technical field
The present invention relates to a kind of 42CrMo Gear Shaft Heat Treatment.
Background technology
Current 42CrMo Gear Shaft Heat Treatment is more complicated, also without unified specification, it does not have unified standard, the gear quality causing production is uneven, a lot of operations that repeat also make under production efficiency, increase the work burden of workman, make the competitiveness of product in market not high simultaneously.For some operators just entered a profession, it does not have a clear and definite method technique, cause, when operation, mistakes and omissions often occur, in some instances it may even be possible to cause serious consequence.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of 42CrMo Gear Shaft Heat Treatment, and this heat-treatment technology method is simple, and the gear various aspects of performance after process is obtained for and is obviously improved.
For achieving the above object, the invention provides a kind of 42CrMo Gear Shaft Heat Treatment, comprise the steps, 1) normalizing: normalizing furnace is heated to 870 DEG C-880 DEG C, is incubated 1h, then according to 20 DEG C/s air cooling；
2) modified: by workpiece heat to 840 DEG C, then oil quenchinng, it is incubated 1h, places into and 480 DEG C of tempering furnaces carry out tempering, be incubated 1-1.5h, air cooling；
3) induction hardening: by workpiece heat to 890 DEG C-900 DEG C in induction furnace, temperature retention time 35s, air cooling, 65 DEG C/s of rate of cooling；
4) lonneal: again by workpiece heat to 150 180 DEG C, is incubated 2.5h, air cooling, 20 DEG C/s of rate of cooling.
The invention has the beneficial effects as follows: the heat-treatment technology method of the present invention is simple, and the gear various aspects of performance after process is obtained for and is obviously improved.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of 42CrMo Gear Shaft Heat Treatment, it is characterised in that comprise the steps, 1) normalizing: normalizing furnace is heated to 870 DEG C-880 DEG C, is incubated 1h, then according to 20 DEG C/s air cooling；
2) modified: by workpiece heat to 840 DEG C, then oil quenchinng, it is incubated 1h, places into and 480 DEG C of tempering furnaces carry out tempering, be incubated 1-1.5h, air cooling；
3) induction hardening: by workpiece heat to 890 DEG C-900 DEG C in induction furnace, temperature retention time 35s, air cooling, 65 DEG C/s of rate of cooling；
4) lonneal: again by workpiece heat to 150 180 DEG C, is incubated 2.5h, air cooling, 20 DEG C/s of rate of cooling.
The heat-treatment technology method of the present invention is simple, and the gear various aspects of performance after process is obtained for and is obviously improved.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
