Abstract
The invention discloses a heat treatment process for a 20SiMn high-speed gear. The heat treatment process is characterized by comprising the following steps: A, performing carburizing treatment at temperature of 900 to 950 DEG C; B, cooling the gear being treated in the step A to 800 to 820 DEG C, then performing oil quenching, keeping temperature between 110 DEG C and 120 DEG C, and performing heat preservation for one hour; and C, tempering the gear being treated in the step B at 180 to 200 DEG C, and performing heat preservation for 2 to 3 hours. The process disclosed by the invention is simple in method, and heating is more thorough, so that internal tenacity of the gear is increased.
Description
Technical field
The present invention relates to the Technology for Heating Processing of a kind of 20SiMn high gear。
Background technology
If existing gear pressure when work is excessive, or practicality is comparatively frequent, it is easy for causing the damage of gear, making between gear can not toe joint be together well, and, gear all in inside, also bad replacing, this results in the application of existing gear, and gear has increasingly higher requirement。
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide the Technology for Heating Processing of a kind of high gear, and this heat-treatment technology method is simple, and heating is more complete, makes the toughness of gear internal improve。
For achieving the above object, the invention provides the Technology for Heating Processing of a kind of 20SiMn high gear, it is characterised in that comprise the steps, A, at 900～950 DEG C of temperature, carry out Carburization Treatment；
B, processing of step A backgear be cooled to 800～820 DEG C again oil quenching maintain the temperature at 110-120 DEG C, be incubated 1 hour；
Gear after C, step B process, 180～200 DEG C of tempering, is incubated 2-3 hour。
The invention has the beneficial effects as follows: present invention process method is simple, heating is more complete, makes the toughness of gear internal improve。
Detailed description of the invention
Technical scheme disclosed by the invention is the Technology for Heating Processing of a kind of 20SiMn high gear, it is characterised in that comprise the steps, A, carries out Carburization Treatment at 930 DEG C of temperature；B, processing of step A backgear be cooled to 820 DEG C again oil quenching maintain the temperature at 110 DEG C, be incubated 1 hour；Gear after C, step B process, 190 DEG C of tempering, is incubated 2-3 hour。
Present invention process method is simple, and heating is more complete, makes the toughness of gear internal improve。
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。
