Description
Technical field
The present invention relates to field of mechanical technique, specifically a kind of bolt one-shot forming mould with safe ditch and screw thread
Tool and processing technology.
Background technology
At present, when processing has the bolt of safe ditch screw thread the common three process of technique：1, cold-heading；2, turning safety
Ditch；3, thread rolling forms screw thread., it is necessary to carry out the processing of three process, not only production efficiency is low for existing technique, and due to
Need to carry out turning, cause production cost too high.
Accordingly, it would be desirable to designing one kind can make safe ditch and the one-time formed die bolt of screw thread and processing technology.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided one kind can make safe ditch and screw thread one-shot forming
Die bolt and processing technology.
In order to achieve the above object, a kind of bolt one-time-shaped mould with safe ditch and screw thread of present invention design, bag
Include die ontology, it is characterised in that：The machined surface of die ontology is provided with screw thread thread rolling structure and projection, screw thread thread rolling structure
One end is located at the front end left side of die ontology, and the other end of screw thread thread rolling structure extends to the rear end left side of die ontology, projection
Positioned at the right side of screw thread thread rolling structure, groove is provided between projection and screw thread thread rolling structure, one end of projection is located at die ontology
Front end right side, the other end of projection extends to the rear end right side of die ontology.
Described screw thread thread rolling body structure surface is provided with skewed thread rolling structure, and the side of skewed thread rolling structure is in wave
Shape.
A kind of processing technology of the bolt with safe ditch and screw thread, it is characterised in that：After bolt is carried out into cold-heading, by spiral shell
The end face of bolt leans against the left side wall of groove, and rotating bolt makes bolt on the machined surface of die ontology from front to back while rolling across
Screw thread thread rolling structure and projection, screw thread thread rolling structure form screw thread on bolt tail surface, and projection is formed on bolt head surface
Safe ditch.
The present invention compared with the existing technology, devises the die bolt and processing work being exclusively used in safe ditch and screw thread
Skill, makes the bolt after cold-heading that safe ditch and screw thread one-shot forming are realized on the mould, not only simplify production technology, improves
Production efficiency, also significantly reduces production cost.

Referring to Fig. 2 and Fig. 6,1 is die ontology；2 is screw thread thread rolling structure；3 is groove；4 is projection.
Specific embodiment
The present invention is described further in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 6, the present invention is a kind of bolt one-time-shaped mould with safe ditch and screw thread, including mould sheet
Body.The machined surface of die ontology 1 is provided with screw thread thread rolling structure 2 and projection 4, and one end of screw thread thread rolling structure 2 is located at mould sheet
The front end left side of body 1, the other end of screw thread thread rolling structure 2 extends to the rear end left side of die ontology 1, and projection 4 is rubbed with the hands positioned at screw thread
The right side of silk structure 2, is provided with groove 3, before one end of projection 4 is located at die ontology 1 between projection 4 and screw thread thread rolling structure 2
End right side, the other end of projection 4 extends to the rear end right side of die ontology 1.
In the present invention, the surface of screw thread thread rolling structure 2 is provided with skewed thread rolling structure, and the side of skewed thread rolling structure is in ripple
Shape wave.
The present invention is when processing has the bolt of safe ditch and screw thread, and concrete technology is as follows：After bolt is carried out into cold-heading, will
The end face of bolt leans against the left side wall of groove 3, rotating bolt, make bolt on the machined surface of die ontology 1 from front to back simultaneously
Screw thread thread rolling structure 2 and projection 4 are rolled across, screw thread thread rolling structure 2 forms screw thread on bolt tail surface, and projection 4 is in bolt head
Surface forms safe ditch.On the one hand the effect of groove 3 is to concede space to the end face of bolt, is easy to bolt to rotate；The opposing party
Face is the spacing of the safe ditch of control and screw thread.
The present invention devises die bolt and the processing technology being exclusively used in safe ditch and screw thread, makes the bolt after cold-heading
Safe ditch and screw thread one-shot forming are realized on the mould, production technology is not only simplify, production efficiency is improve, also significantly dropped
Low production cost.
