Abstract
The invention discloses a kind of studs upsetting ball techniques, include the following steps, step A, blank, and raw material are cut into the preliminary bar material of spiro rod length；Step B, by one end circle of contact angle of the preliminary bar material in step A；The other end of bar material in step B is cut chamfering by step C；The rounded end of bar material in step C is processed into circular arc spherical surface, chamfered end is processed into fillet surface and fillet surface by step D；The surface of bar material in step D is processed growth end threaded portion from circular arc spherical surface, the surface of bar material is processed into short end threaded portion from stopping surface angle by step E；Step F, in length end grain portion and short end threaded portion difference threading.The present invention's is simple and efficient to handle, can effectively and quickly realize the processing of double threaded screw, and can effectively distinguish long end and short end, so as to advantageously ensure that the precision of processing, improve processing efficiency to a certain extent, stability in use is good and highly practical.
Description
Technical field
The invention belongs to stud processing method technical fields, and in particular to a kind of studs upsetting ball technique.
Background technology
When the long end reach of studs is differed with short end reach less than 5mm, in order to more easily discriminate long end
It with short end, needs to be processed into circular arc spherical surface shape at long end, traditional technology is that first cold-heading both ends spiral shell base is molded, a chamfer, separately
One end needs postorder turnery processing end face into arc ball planar, and processing efficiency is relatively low.
Invention content
The object of the present invention is to provide a kind of simple operation and the studs upsetting ball technique of processing efficiency can be improved.
The technical solution for realizing the object of the invention is a kind of studs upsetting ball technique, is included the following steps,
Raw material are cut into the preliminary bar material of spiro rod length by step A, blank；
Step B, by one end circle of contact angle of the preliminary bar material in step A；
The other end of bar material in step B is cut chamfering by step C；
The rounded end of bar material in step C is processed into circular arc spherical surface by step D, and chamfered end is processed into fillet surface and is fallen
Edged surface；
The surface of bar material in step D is processed growth end threaded portion, by the surface of bar material from by step E from circular arc spherical surface
Face angle is processed into short end threaded portion；
Step F, in length end grain portion and short end threaded portion difference threading.
In step C, the length for cutting chamfering is more than the length at circle of contact angle.
In the step D, the length of circular arc spherical surface is identical with the length of fillet surface.
In step E, the length of long end threaded portion is less than 5mm than the length difference of short end threaded portion.
The present invention has positive effect：The present invention's is simple and efficient to handle, can effectively and quickly realize double threaded screw
Processing, and long end and short end can be effectively distinguished, so as to advantageously ensure that the precision of processing, processing is improved to a certain extent
Efficiency, stability in use are good and highly practical.
Description of the drawings
In order to make the content of the present invention more clearly understood, it is right below according to specific embodiment and with reference to attached drawing
The present invention is described in further detail, wherein：
Fig. 1 is the workflow schematic diagram of the present invention.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the present invention, and wherein Fig. 1 is the workflow schematic diagram of the present invention.
See Fig. 1, a kind of studs upsetting ball technique includes the following steps,
Raw material are cut into the preliminary bar material of spiro rod length by step A, blank；
Step B, by one end circle of contact angle of the preliminary bar material in step A；
The other end of bar material in step B is cut chamfering by step C；
The rounded end of bar material in step C is processed into circular arc spherical surface by step D, and chamfered end is processed into fillet surface and is fallen
Edged surface；
The surface of bar material in step D is processed growth end threaded portion, by the surface of bar material from by step E from circular arc spherical surface
Face angle is processed into short end threaded portion；
Step F, in length end grain portion and short end threaded portion difference threading.
In step C, the length for cutting chamfering is more than the length at circle of contact angle.
In the step D, the length of circular arc spherical surface is identical with the length of fillet surface.
In step E, the length of long end threaded portion is less than 5mm than the length difference of short end threaded portion.
The present invention's is simple and efficient to handle, can effectively and quickly realize the processing of double threaded screw, and can effectively distinguish
Long end and short end so as to advantageously ensure that the precision of processing, improve processing efficiency to a certain extent, and stability in use is good and real
It is strong with property.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And these
The obvious changes or variations that the connotation for belonging to of the invention is extended out still fall within protection scope of the present invention.
