Description
Technical field
The present invention relates to a kind of processing technology, more particularly to a kind of bolt processing technic featuring.
Background technology
Bolt：Machine components, the cylindrical threaded fastener of adapted nut.External screw thread (is carried by head and screw rod
Cylinder) a kind of fastener dimerous, need to coordinate with nut, for being fastenedly connected two parts with through hole.
This type of attachment claims to be bolted.It as nut is screwed off from bolt, and can separate the two parts, therefore be bolted
It is to belong to be detachably connected.Since it is critical component, have higher requirements to its processing quality, intensity and toughness.
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 high in machining efficiency, measured bolt processing technic featuring of matter.
【2】The technical solution solved the problems, such as
The present invention provides a kind of bolt processing technic featuring, and the bolt includes head and screw rod (carries externally threaded cylinder
Body), the processing technology comprises the following steps：
A1, stock：According to the small selection of the specification of bolt and car blank；
A2, annealing：Full annealing is carried out to blank, 750~800 DEG C, when duration 2~3 is small are heated in stove, blank
Be furnace-cooled to 500 DEG C come out of the stove it is air-cooled；
A3, hot forging：Bolt head, rear natural cooling are forged out with 800~900 DEG C of temperature；
A4, pickling：Acid cleaning process technique:Hydrochloric acid → washing → grass is washed → wash (60-80 DEG C) → phosphate → washing →
Lubricant；
A5, three times punching press：At room temperature, screw rod is stamped out for the first time, selects 125~160 tons of hydraulic press, second of punching
Screw thread is extruded, selects 63~80 tons of hydraulic press, third time selects Z28 series rolled thread machined threads；
A6, heat treatment：To bolt carry out quenching treatment after oil cooling, and degreasing processing after temper, finally come out of the stove
Water cooling；
A7, inspection：To be tested according to bolt specification；
A8, nigrescence：Blackening process is carried out to above-mentioned pieces O.K., reaches antirust purpose.
【3】Beneficial effect

Water cooling；
A7, inspection：To be tested according to bolt specification；
A8, nigrescence：Blackening process is carried out to above-mentioned pieces O.K., reaches antirust purpose.
Complete after blacking, bolt is inspected by random samples again, including intensity, hardness and tensile strength test.
Bolt processing technic featuring of the present invention, operating procedure is clear, and high in machining efficiency and quality is good, with good intensity, firmly
Degree and toughness.
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.
