Description
Technical field
The present invention relates to a kind of axial workpiece Technology for Heating Processing, 45 Heat-Treatment of Steel techniques of more particularly to a kind of axle.
Background technology
With continuous development of the people to machinery, axle is constantly applied on the instruments such as automobile, steamer, aircraft, lathe, right
Axle also needs to have higher requirement therewith.Axle is exactly to be through the cylinder thing among bearing or among wheel or among gear
Part, but it is partially square also to have.Axle is support rotary part and turned round therewith to transmit motion, moment of torsion or moment of flexure
Machine components.Generally round metal is shaft-like, and each section can have different diameters.The part for making gyration in machine is just mounted in axle
On.Existing axial workpiece then has the following disadvantages as used normative heat treatment technique:Fatigue fracture, overload breakage, elasticity become
Shape is excessive etc..
The content of the invention
【1】Technical problems to be solved
Promote axle to possess good plasticity, toughness the technical problem to be solved in the present invention is to provide a kind of, have again good
45 Heat-Treatment of Steel techniques of the axle of intensity and higher hardness.
【2】The technical scheme solved the problems, such as
The present invention provides a kind of axle and includes the component of following percentage by weight with 45 Heat-Treatment of Steel techniques, 45 ladle:
Carbon:0.42~0.50;Manganese:0.50~0.80;Silicon:0.17~0.37;Chromium:Less than or equal to 0.25;Nickel:Less than or equal to 0.30;Copper:
Less than or equal to 0.25;Inevitable impurity:Less than 0.1;Surplus is iron;Characterized in that, its Technology for Heating Processing is including following
Step:
A1 Quenching Treatments:Workpiece be heated in stove temperature for 810~82 DEG C when, be incubated 10~30 minutes, workpiece is come out of the stove
Quenched afterwards in saline solution, improve the hardness and wearability of metal;
The processing of a2 high temperings:Workpiece be heated in stove temperature for 560~600 DEG C when, be incubated 1~2 hour, after coming out of the stove
Natural cooling, there is excellent comprehensive mechanical property.
Further, the saline solution is 10% saline solution, after 45 steel enters water, takes and makees regular motion slow cooling
Method, motion stopping can go out water-air cooling or oil cooling, slow down cooling velocity phase, surface hardening crackle.
Further, the oily cooling medium be animal oil, vegetable oil, mineral oil, semi synthetic base oils etc. any one, slow down
Cooling velocity phase, surface hardening crackle.
【3】Beneficial effect
45 Heat-Treatment of Steel techniques of axle of the present invention, there is good plasticity, toughness, there is good intensity and higher again
Hardness, so as to improve the total quality of axis products and mechanical life, save equipment cost.
Embodiment
The embodiment of the present invention is described in detail below.
The present invention provides a kind of axle and includes the component of following percentage by weight with 45 Heat-Treatment of Steel techniques, 45 ladle:Carbon:

In equal to 0.25;Inevitable impurity:Less than 0.1;Surplus is iron;Its Technology for Heating Processing comprises the following steps:
A1 Quenching Treatments:Workpiece be heated in stove temperature for 810~825 DEG C when, be incubated 10~30 minutes, workpiece is come out of the stove
Afterwards enter 10% saline solution take make regular motion slow cooling method quenching, motion stopping can go out water-air cooling or oil cooling;
The processing of a2 high temperings:Workpiece be heated in stove temperature for 560~600 DEG C when, be incubated 1~2 hour, after coming out of the stove
Natural cooling.
The oily cooling medium of this in the present invention be with good cooling performance, good thermal oxidation stability, high-flash and
Burning-point, low viscosity and the low animal oil (such as lard) of moisture, vegetable oil (such as rape seed oil, salad oil), mineral oil (machine oil),
Semi synthetic base oils (mineral oil adds artificial oil, is exactly the special quenching oil of the various trades mark), artificial oil (it is artificial synthesized, the various trades mark
Special quenching oil) etc. any one, oil cooling medium should also be nontoxic, tasteless, disposable, environmentally safe in addition.
45 Heat-Treatment of Steel techniques of axle of the present invention, there is good plasticity, toughness, there is good intensity and higher again
Hardness, so as to improve the total quality of axis products and mechanical life, save equipment cost.
Described 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.
