Abstract

The invention discloses a spindle box gear heat treatment technology. The technology comprises blanking, blank forging, normalization, rough machining, hardening and tempering, fine finishing (gear hobbing), high frequency induction heating quenching, low temperature tempering and grinding. The technology has simple processes, is free of many repeated processes and improves work efficiency.

Description

A kind of main spindle box gear heat treatment technique
Technical field
The present invention relates to a kind of main spindle box gear heat treatment technique.
Background technology
Current main spindle box gear heat treatment technics comparing is complicated, also without unified specification, it does not have unified standard, the main spindle box 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 main spindle box gear heat treatment technique, and the method technique is simple, eliminates a lot of repeatability operation, improves work efficiency.
For achieving the above object, the invention provides a kind of main spindle box gear heat treatment technique, it is characterized in that, comprise the steps, blanking → forge blank → normalizing → roughing → modified → polish (gear hobbing) → high-frequency induction quenching → lonneal → grinding.
Further, described normalizing process is first furnace temperature when being heated to 840 DEG C ± 10 DEG C, is then loaded by workpiece, is incubated 2h, air cooling.
Further, when hardening and tempering process is first furnace temperature to be heated to 830 DEG C, workpiece is put into heat-treatment furnace and is heated, water hardening, cooling medium is mass fraction be 25% NaCl aqueous solution, then carry out tempering, temperature is 570 ± 10 DEG C, temperature retention time 50min, and the type of cooling is oil cooling.
Further, taking frequency is 250KHZ, and full-depth tooth heats simultaneously, and cooling means is injection water-cooled, and cooling medium is 10-15 DEG C of aqueous solution.
Further, described lonneal refers to that temperature is 180 ± 10 DEG C, and tempering time is 1h.
The invention has the beneficial effects as follows: the inventive method technique is simple, eliminate a lot of repeatability operation, improve work efficiency.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of main spindle box gear heat treatment technique, it is characterized in that, comprise the steps, blanking → forge blank → normalizing → roughing → modified → polish (gear hobbing) → high-frequency induction quenching → lonneal → grinding.
Further, described normalizing process is first furnace temperature when being heated to 840 DEG C ± 10 DEG C, is then loaded by workpiece, is incubated 2h, air cooling.
Further, when hardening and tempering process is first furnace temperature to be heated to 830 DEG C, workpiece is put into heat-treatment furnace and is heated, water hardening, cooling medium is mass fraction be 25% NaCl aqueous solution, then carry out tempering, temperature is 570 ± 10 DEG C, temperature retention time 50min, and the type of cooling is oil cooling.
Further, taking frequency is 250KHZ, full-depth tooth heats simultaneously, and cooling means is injection water-cooled, and cooling medium is 10-15 DEG C of aqueous solution.
Further, described lonneal refers to that temperature is 180 ± 10 DEG C, and tempering time is 1h.
Through the main spindle box gear of this heat treatment method processing, intensity, hardness all significantly improves, and processing characteristics is better, it is possible to bear relatively larger load impacting.
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.
