Abstract
The present invention provides a kind of screw heat treatment process, comprises the following steps：A1, carry out screw surface degreasing and cleaning iron filings；A2, the pre-heat treatment：Two-part preheating is carried out to screw, first segment temperature is 500~550 DEG C, and duration 10 minutes, second segment temperature is 750~850 DEG C, duration 15~20 minutes；A3, quenching treatment：Screw be heated in stove temperature for 700~800 DEG C when, keep the temperature 20~30 minutes, workpiece is come out of the stove oil cooling；A4, high tempering processing：Screw be heated in stove temperature for 400~500 DEG C when, keep the temperature 40~60 minutes, workpiece is come out of the stove water cooling.Screw heat treatment process of the present invention, step is clear, quality is good, has good plasticity, toughness, intensity and hardness, so as to improve the service life of screw.
Description
Technical field
The present invention relates to a kind of heat treatment process, more particularly to a kind of screw heat treatment process.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The instrument of implements parts.Screw is the general saying of fastener, daily pet phrase.Screw is work indispensable in daily life
Industry necessity, as long as there is industry on the earth, then the function of screw is forever important.Since it is critical component, to it
Hardness, toughness and intensity have higher requirements.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of step is clear, the measured screw heat treatment process of matter.
【2】The technical solution solved the problems, such as
The present invention provides a kind of screw heat treatment process, and the screw material is quenched and tempered steel, and the heat treatment process includes
Following steps：
A1, carry out screw surface degreasing and cleaning iron filings；
A2, the pre-heat treatment：Two-part preheating is carried out to screw, first segment temperature is 500~550 DEG C, duration 10 minutes, the
Two sections of temperature are 750~850 DEG C, duration 15~20 minutes；
A3, quenching treatment：Screw be heated in stove temperature for 700~800 DEG C when, keep the temperature 20~30 minutes, workpiece goes out
Furnace oil is cold；
A4, high tempering processing：Screw be heated in stove temperature for 400~500 DEG C when, keep the temperature 40~60 minutes, work
Part is come out of the stove water cooling.
Further, the oil cooling but medium for animal oil, vegetable oil, mineral oil, semi synthetic base oils etc. any one.
【3】Beneficial effect
Screw heat treatment process of the present invention, step is clear, quality is good, has good plasticity, toughness, intensity and hardness,
So as to improve the service life of screw.
Embodiment
The embodiment of the present invention is described in detail below.
The present invention provides a kind of screw heat treatment process, which is quenched and tempered steel, which includes following
Step：
A1, carry out screw surface degreasing and cleaning iron filings；
A2, the pre-heat treatment：Two-part preheating is carried out to screw, first segment temperature is 500~550 DEG C, duration 10 minutes, the
Two sections of temperature are 750~850 DEG C, duration 15~20 minutes；
A3, quenching treatment：Screw be heated in stove temperature for 700~800 DEG C when, keep the temperature 20~30 minutes, workpiece goes out
Furnace oil is cold；
A4, high tempering processing：Screw be heated in stove temperature for 400~500 DEG C when, keep the temperature 40~60 minutes, work
Part is come out of the stove water cooling.
After completing heat treatment, quality testing, including hardness, toughness and strength test are sampled to screw.
In the present embodiment the oil cooling but medium for animal oil, vegetable oil, mineral oil, semi synthetic base oils etc. any one.
Screw heat treatment process of the present invention, step is clear, quality is good, has good plasticity, toughness, intensity and hardness,
So as to improve the service life of screw.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
