Description

A kind of right angle hose coupling treatment process
Technical field
The present invention relates to a kind for the treatment of process, more particularly to a kind of right angle hose coupling treatment process.
Background technology
For right angle hose coupling easy to dodge adapter road, installation and removal are more convenient, quick.Since it is critical component, because This has higher requirements its toughness, intensity and pull resistance etc..
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 for the treatment of effeciency height, the measured right angle hose coupling processing work of matter Skill.
【2】The technical solution solved the problems, such as
The present invention provides a kind of right angle hose coupling treatment process, and the treatment process comprises the following steps：
A1, cleaning：Workpiece is cleared up；
A2, annealing：By workpiece heat to 1000~1100 DEG C before hot forging, when duration 1~2 is small, workpiece is with furnace cooling But to 550 DEG C, come out of the stove air-cooled；
A3, quenching treatment：After roughing to workpiece carry out quenching treatment, 750~800 DEG C of temperature, duration 50~60 minutes, Come out of the stove oil cooling；
A4, average tempering processing：250~350 DEG C, when duration 2~3 is small are reheated to after workpiece quenching, is come out of the stove air-cooled；
A5, surface hardening processing：Quenching treatment, 800~900 DEG C of temperature, temperature to model are carried out to workpiece surface before polishing Value is enclosed to come out of the stove immediately water cooling；
A6, cleaning：Workpiece is subjected to degreasing processing, washes and dries；
A7, electroplating processes：Electrodeposited chromium is carried out to workpiece surface.
Further, the electrodeposited chromium is environmentally friendly trivalent chromium.
【3】Beneficial effect
Hose coupling treatment process in right angle of the present invention, processing step is clear, and treatment effeciency is high and quality is good, has well Toughness, wearability and tension, torsional strength.
Brief description of the drawings
Fig. 1 is the structure diagram of hose coupling treatment process in right angle of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is discussed in detail.
Refering to Fig. 1, the present invention provides a kind of right angle hose coupling treatment process, which comprises the following steps：
A1, cleaning：Workpiece is cleared up；
A2, annealing：By workpiece heat to 1000~1100 DEG C before hot forging, when duration 1~2 is small, workpiece is with furnace cooling But to 550 DEG C, come out of the stove air-cooled；
A3, quenching treatment：After roughing to workpiece carry out quenching treatment, 750~800 DEG C of temperature, duration 50~60 minutes, Come out of the stove oil cooling；
A4, average tempering processing：250~350 DEG C, when duration 2~3 is small are reheated to after workpiece quenching, is come out of the stove air-cooled；
A5, surface hardening processing：Quenching treatment, 800~900 DEG C of temperature, temperature to model are carried out to workpiece surface before polishing Value is enclosed to come out of the stove immediately water cooling；
A6, cleaning：Workpiece is subjected to degreasing processing, washes and dries；
A7, electroplating processes：Electrodeposited chromium is carried out to workpiece surface.
After completing plating, right angle hose coupling is inspected by random samples, including wearability, resistance to torsion and pull resistance test.
The electrodeposited chromium is environmentally friendly trivalent chromium in the present embodiment, itself electroplate liquid environmental pollution and toxicity than Cr VI will Small is more.
Hose coupling treatment process in right angle of the present invention, processing step is clear, and treatment effeciency is high and quality is good, has well Toughness, wearability and tension, torsional strength.
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.
