Description
Technical field
The present invention relates to a kind of bolt, and in particular to a kind of outer six flower flange face bolt and its manufacture method, outer six flowers method
Blue face bolt is used for the fastening of high-speed train braking wheel disc.
Background technology
In the prior art, the domestic high ferro braking wheel disc fastening bolt used is the nonstandard bolt of import, and the import is nonstandard
Bolt unit price is expensive, delivery cycle length, third party's detection through mechanical industry spare part in common use product quality supervision inspection center,
Its tensile strength can not comply fully with 10.9 grades of standard requirements of ISO898-1.Meanwhile the import bolt exercises 300,000 public affairs in high ferro
In in segmentation unload in detection, it is found that indivedual bolts have phenomenon of rupture.In addition, traditional outer-hexagonal or the spiral shell of hexagon socket head cap screw
Head difficulty of processing is smaller, is easy to copy.However, due to bullet train to brake wheel disc fastening bolt intensity and toughness it is comprehensive
It is higher to close performance requirement, once there is underproof Counterfeit Item, serious potential safety hazard can be produced.
For these reasons, innovate reasonable, safe, the new braking wheel disc fastening bolt of a kind of high-quality, cost and its
Manufacture method；The production domesticization of the bolt is realized, turns into the problem that our compatriots need research badly.
The content of the invention
It is an object of the invention in order to substitute import bolt, reduce cost, overcome the shortcomings of import bolt, there is provided one
Six flower flange face bolt outside kind, the bolt is not easy to copy, and can meet 400 degrees Celsius of height of bullet train Multiple disc brake requirement
Subzero 40 degrees Celsius of the reliability and low temperature of warm intensity（I.e. high and low temperature continues alternation）It is the shock resistances of adverse circumstances, anti-vibration, anti-
The combination property requirement of fatigue fracture.
The purpose of the present invention is achieved through the following technical solutions：A kind of outer six flowers flange face bolt, by from top to bottom
The outer six flower ring flange screw heads and all-teeth screw set gradually is formed, and the outer six flower ring flange screw head is by body head, setting
Formed in the ring flange of body head lower end and six fillets being uniformly distributed on body head circumference.
The difficulty of processing of the outer six flowers ring flange screw head of the present invention is higher, can effectively avoid copying.All-teeth screw can
The adhesion of bolt and connector is improved to greatest extent.
The outer layer of the outer six flower ring flange screw head and the all-teeth screw is provided with Dacromet/steel, and surface, which uses, to be reached
Crow PROCESS FOR TREATMENT, it can effectively ensure that the moisture proof, acid-resistance, the corrosion resistance of sand-proof of bolt.
It is another object of the present invention to for overcome the deficiencies in the prior art, there is provided a kind of system of outer six flowers flange face bolt
Method is made, the outer six flowers flange face bolt of this method manufacture can be used in being fastened securely for high-speed train braking wheel disc.
It is another object of the present invention to what is be achieved through the following technical solutions：A kind of manufacturer of outer six flowers flange face bolt
Method, comprise the following steps successively：1）Raw material feeds detect；2）Fracture；3）Performing hot-heading forming；4）Heat treatment；5）Normal temperature and 400 take the photograph
Family name's degree Testing Tensile Strength at Elevated Temperature detects and the test of subzero 40 degrees Celsius of ballistic works；6）Finishing；7）Refine screw thread embryo footpath；8）Rolled thread；
9）100% magnetic powder inspection；10）Surface treatment；
To ensure reliability and low temperature subzero 40 degree Celsius of the bolt in 400 celsius temperature intensity（I.e. high and low temperature continues
Alternation）The shock resistance of Service Environment, anti-vibration, fatigue crack-resistant performance, raw material selection B16 steel, the chemical Composition Control of B16 steel
Scope is：C%:0.36-0.47；P%:≤0.035；S%:≤0.040；Si%:0.15-0.35；Cr%:0.80-1.15；Mn%:
0.45-0.70；Mo%：0.50-0.65；V%:0.25-0.35；Al%:≤0.015.
To avoid material defectses, the reliable quenching degree of bolt subsequent heat treatment and temper resistance are ensured, in processing
Before, raw material are carried out with chemical composition spectrum analysis, the metallographic detection of raw material field trash and feed stock material defect successively
Ultrasound examination.
Above-mentioned manufacture method can ensure material quality, effectively avoid bolt surface oxidation, decarburization and threaded folding from showing
The generation of elephant.Ensure the reliability and subzero 40 degrees Celsius of low temperature of 400 celsius temperature intensity when the fastening of finished product bolt is on active service（I.e.
High and low temperature continues alternation）The shock resistance of adverse circumstances, anti-vibration, the overall target of fatigue crack-resistant.
