Description
Technical field
The utility model is related to field of mechanical technique, specifically a kind of bolt with safe ditch and screw thread once into
Pattern has.
Background technology
At present, the common three process of technique when processing has the bolt of safe ditch screw thread：1, cold-heading；2, turning safety
Ditch；3, thread rolling forms screw thread.Existing technique is, it is necessary to carry out the processing of three process, and not only production efficiency is low, and due to
Need to carry out turning, cause production cost too high.
Accordingly, it would be desirable to which safe ditch and the one-time formed die bolt of screw thread can be made by designing one kind.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art to make safe ditch and screw thread once there is provided one kind
The die bolt of shaping.
In order to achieve the above object, a kind of bolt one-shot forming mould with safe ditch and screw thread of the utility model design
Tool, including 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
One end of structure is located on the left of the front end of die ontology, and the other end of screw thread thread rolling structure extends to a rear end left side for die ontology
Side, projection is located 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 mould
On the right side of the front end for having body, the other end of projection is extended on the right side of the rear end 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.
The utility model compared with the existing technology, devises the die bolt being exclusively used in safe ditch and screw thread, made cold
Bolt after upsetting realizes safe ditch and screw thread one-shot forming on the mould, not only simplify production technology, improves production effect
Rate, also significantly reduces production cost.

Referring to Fig. 2 and Fig. 6,1 is die ontology；2 be screw thread thread rolling structure；3 be groove；4 be projection.
Embodiment
The utility model is described further in conjunction with accompanying drawing.
Referring to Fig. 1-Fig. 6, the utility model is a kind of bolt one-time-shaped mould with safe ditch and screw thread, including mould
Has 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
On the left of the front end for having body 1, the other end of screw thread thread rolling structure 2 is extended on the left of the rear end of die ontology 1, and projection 4 is located at spiral shell
The right side of line thread rolling structure 2, is provided with groove 3, one end of projection 4 is located at die ontology 1 between projection 4 and screw thread thread rolling structure 2
Front end on the right side of, the other end of projection 4 is extended on the right side of the rear end of die ontology 1.
In the utility model, the surface of screw thread thread rolling structure 2 is provided with skewed thread rolling structure, the side of skewed thread rolling structure
Undulate.
The utility model is when processing has the bolt of safe ditch and screw thread, and concrete technology is as follows：Bolt is subjected to cold-heading
Afterwards, the end face of bolt leans against to the left side wall of groove 3, rotating bolt, make bolt on the machined surface of die ontology 1 from front to back
Screw thread thread rolling structure 2 and projection 4 are rolled across simultaneously, and 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；Separately
On the one hand it is the spacing of the safe ditch of control and screw thread.
The utility model devises the die bolt being exclusively used in safe ditch and screw thread, makes the bolt after cold-heading in the mould
Safe ditch and screw thread one-shot forming are realized on tool, production technology is not only simplify, production efficiency is improved, also significantly reduces life
Produce cost.
