Abstract
The invention discloses one mould two of one kind to rush screw mold, including die ontology and screw plate, the screw plate is corresponding with die ontology but is not attached to, the die ontology includes main mould, low punch, upper punch, cut-off-die and red needle, the red needle is embedded in main mould center, the main mould upper surface and the low punch lower face that connects are connected upper punch, and corresponding undershoot headgear, upper punch set, the cut-off-die connection main mould and upper punch set are respectively equipped with outside the low punch, upper punch.The present invention provides more preferable safeguard measure when screw is processed, and each link compatible degree is good, vibrations are small compact-sized, and thread rolling process is individually proposed, it is high to make precision.
Description
Technical field
The present invention relates to a kind of screw, screw rod mould, is specially that an a kind of mould two rushes screw mold.
Background technology
Screw is also screw, and screw can be divided into, according to use, three classes：Machine screw, holding screw and specific use spiral shell
Nail.Screw is mainly used for fixing the relative position between two parts, play a part of positioning pin, is fixedly connected as a kind of
Standard component, various fields all use screw.Just punching is used as one of necessary cold forging die in screw production industry, it is main
For the predeformation of material, the control accuracy of its size will meet the requirement in screw production process.Existing mould is just rushed and returned
Repair rate height, low production efficiency, service life is short, product quality can not strict guarantee, its it is sealed or dismounting screw when easy stripped thread,
Secondary abrasion is likely to occur in process, product is not smart and influences the service life of mould, it is taken the lead with thread rolling in same work
Carried out in sequence, be difficult to control the variation of screw thread.
To solve the above problems, therefore it is proposed that an a kind of mould two rushes screw mold.
The content of the invention
The defects of the technical problem to be solved in the present invention is the prior art is overcome, there is provided an a kind of mould two rushes screw mold.
In order to solve the above technical problem, the present invention provides following technical solution：
One mould two of one kind of the invention rushes screw mold, including die ontology and screw plate, the screw plate and die ontology
Corresponding but be not attached to, the die ontology includes main mould, low punch, upper punch, cut-off-die and red needle, and the red needle is embedded in master
Mould center, the main mould upper surface and the low punch lower face that connects are connected upper punch, and the low punch, upper punch are respectively equipped with outside
Corresponding undershoot headgear, upper punch set, the cut-off-die connection main mould and upper punch set.
Further, the main mould inner wall is equipped with friction plate and upper surface is connected with circular hollow turntable.
Further, the low punch is internally provided with evanohm spring.
Further, it is furnished with scissors in the cut-off-die, the long nut outside cut-off-die is stretched out in scissors one end connection.
Further, the upper punch working face wraps up smooth crash roll.
Further, the screw plate is made of two pieces of working plates, is respectively fixed plate and movable plate.
The beneficial effect that is reached of the present invention is：By setting friction plate in main mould inner wall, increase frictional force and cause screw
Process more stable, worked by circular hollow turntable rotation so that suppress more uniform, the cooperation of evanohm spring, crash roll
Use, reduce vibrations and abrasion caused by compacting contact, add the service life of machine, there is provided more preferable safeguard measure,
Each link compatible degree is good compact-sized, and thread rolling process is individually proposed, is needed to adjust depth, distribution and the shape of screw thread according to processing
Shape, it is high to make precision.

Embodiment
The preferred embodiment of the present invention is illustrated below in conjunction with attached drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As shown in Figs. 1-2, an a kind of mould two rushes screw mold, including die ontology 1 and screw plate 12, the screw plate 12
Corresponding with die ontology 1 but be not attached to, the die ontology 1 includes main mould 2, low punch 3, upper punch 8, cut-off-die 7 and red needle
13, the red needle 13 is embedded in the center of main mould 2, and 2 upper surface of main mould and low punch 3 lower face that connects are connected upper punch 8, institute
State and corresponding undershoot headgear 4, upper punch set 9 are respectively equipped with outside low punch 3, upper punch 8, the cut-off-die 7 connects main mould 2 and upper punching
Headgear 9.
2 inner wall of main mould is equipped with friction plate and upper surface is connected with circular hollow turntable 14, and increasing friction force causes interior
Portion's workpiece is more firm, and turntable causes 2 rotary work of main mould, and part compacting is more well-balanced, and the low punch 3 is internally provided with evanohm
Spring 5, high temperature resistant, rigidity are big, long lifespan, are furnished with scissors 6 in the cut-off-die 7, and 6 one end of scissors connection is stretched out outside cut-off-die 7
Long nut, control the scissors residence time, it is short to unclamp the residence time, shortens the then residence time and grows, and the upper punch 8 works bread
Smooth crash roll 15 is wrapped up in, rigid contact protection processing part is reduced and prolongs the service life, the screw plate 12 is by two pieces of work
Plate is formed, and is respectively fixed plate 10 and movable plate 11, easy to extrusion forming, the low surface quality of processing cost is good.
It should be noted that：When rushing screw mold using this kind mould two, in the work of a punch die after metal material cut-out
With in 2 hole of lower push-in main mould, turntable 14 drives main mould 2 to rotate, and undershoot headgear 4 fixes 3 punch of low punch and completes blank head
First one-step forming, the timing that cooperates of scissors 6 and long nut are cut, upper punch 8 be processed further after by screw ejection die.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To modify to the technical solution described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent replacement, improvement and so on, should be included in the present invention's
Within protection domain.
