Standby loss, while the plenty of time is also consumed on the process-cycle, it is a large amount of in the middle of milling stern notch process to use diesel oil virtually to ring
Border increased safely burden and risk.
The content of the invention
The present invention specifically provides a kind of bolt, and shank of bolt 1 is provided with the scrapings groove 2 for reinforcing locking effect at bolt tail.
Scrapings groove 2 at bolt tail can play reinforcing locking, beneficial to chip removal, anti-skidding effect.
The cross section of scrapings groove 2 is class sector structure.
A kind of particular manufacturing craft for manufacturing bolt, die main body is in hollow cylindrical structure, by outer layer 3, internal layer 4 and milling tail knife
5 are constituted, and outer layer 3 and internal layer 4 are hollow cylindrical structure, milling tail knife 5 be arranged in outer layer 3 it is hollow in, internal layer 4 is fixed on outer layer
Between 3 and milling tail knife 5.
Specifically, the main body of milling tail knife 5 is sector structure, its inner bottom for being arranged in internal layer 4 in conoid structure, section
End.Milling tail knife 5 is corresponding with the structure of scrapings groove 2.
A kind of method for manufacturing bolt, cold-heading in the middle of particular manufacturing craft is placed into by blank bolt, forms semi-finished product bolt；Take
Go out semi-finished product, go defeathering to be cut, form finished product；Quality inspection, storage.
The present invention by the milling tail knife structure of mould inside, be able to will carry the product cold extrusion of milling stern notch demand once into
Type, reduces the independent milling tail operation after cold-heading.
Using the cold extrusion die described in invention, can be during cold-heading molding, by improving mould structure, directly
Formed milling stern notch, banned behind milling tail operation.
The present invention disposably manufactures milling tail bolt using cold treatment process, not only reduces the technological process of independent milling tail,
And the diesel oil that milling tail technological process is used is reduced, high degree reduces environmental risk and pollution level；Cut down simultaneously
Employee spending, has saved entreprise cost.
Brief description of the drawings
The present invention is described in further details with reference to Figure of description：
Fig. 1 is bolt arrangement schematic diagram；
Fig. 2 is the structural representation of particular manufacturing craft.
Specific embodiment
Reference numeral explanation：
