Abstract
The utility model discloses a mould no. 2 a towards screw mold, including mould body and screwplate, the screwplate is corresponding but continuous with the mould body, the mould body includes fundamental mode, low punch, upper punch, shear die and towards the needle, inlay in fundamental mode central authorities towards the needle, the upper punch was connected to the terminal surface under the fundamental mode up end met with the low punch, low punch, upper punch are equipped with corresponding lower punch sleeve outward respectively, go up punch sleeve, shear die connects fundamental mode and last punch sleeve. The utility model discloses it provides better safeguard measure man -hour to add at the screw, and each link degree of agreeing with is good, shake little compact structure, proposes the thread rolling process alone, and the preparation precision is high.
Description
Technical field
This utility model is related to a kind of screw, screw rod mould, and a specially 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 in fixing the relative position between two parts, play a part alignment pin, is fixedly connected as a kind of
Standard component, various fields all use screw.As one of necessary cold forging die in screw production industry, it is main for just punching
For the predeformation of material, the control accuracy of its size will meet the requirement in screw production process.At the beginning of existing mould, punching is returned
Rate of repairing is high, low production efficiency, and service life is short, product quality cannot strict guarantee, easy stripped thread during its sealed or dismounting screw,
It is likely to occur secondary abrasion, product is not smart and affects the mold use life-span, and it is taken the lead with thread rolling in same work in the course of processing
Carry out in sequence, the variation of wayward screw thread.
For solving the above problems, therefore it is proposed that an a kind of mould two rushes screw mold.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, provides an a kind of mould two to rush screw plate
Tool.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme：
This utility model one kind one mould two rushes screw mold, including die ontology and screw plate, described screw plate and mould
Body is corresponding but is not attached to, and described die ontology includes main mould, low punch, upper punch, cut-off-die and red needle, and described red needle is inlayed
In main mould central authorities, the described main mould upper surface and low punch lower surface that connects is connected upper punch, distinguishes outside described low punch, upper punch
It is provided with corresponding undershoot headgear, upper punch set, described cut-off-die connects main mould and upper punch set.
Further, described main mould inwall is provided with friction plate and upper surface is connected with circular hollow rotating disk.
Further, it is provided with evanohm spring inside described low punch.
Further, it are furnished with shears in described cut-off-die, described shears one end connects the long nut stretching out outside cut-off-die.
Further, the smooth crash roll of described upper punch work surface parcel.
Further, described screw plate is made up of two pieces of working plates, respectively fixed plate and movable plate.
The beneficial effect that this utility model is reached is：By arranging friction plate in main mould inwall, increase frictional force and make
Screw processing is more stable, worked so that suppress more uniformly by circular hollow turntable rotation, evanohm spring, crash roll
Use cooperatively, reduce the vibrations producing during compacting contact and abrasion, increased the service life of machine, provide more preferable protection to arrange
Apply, the good compact conformation of each link compatible degree, thread rolling operation is individually proposed, need to adjust depth, the distribution of screw thread according to processing
And shape, make high precision.

Specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
Embodiment 1
As shown in Figure 1-2, an a kind of mould two rushes screw mold, including die ontology 1 and screw plate 12, described screw plate 12
Corresponding with die ontology 1 but be not attached to, described die ontology 1 includes main mould 2, low punch 3, upper punch 8, cut-off-die 7 and red needle
13, described red needle 13 is embedded in main mould 2 central authorities, and described main mould 2 upper surface and low punch 3 lower surface that connects is connected upper punch 8, institute
State low punch 3, upper punch 8 is respectively equipped with outward corresponding undershoot headgear 4, upper punch set 9, described cut-off-die 7 connects main mould 2 and Shang Chong
Headgear 9.
Described main mould 2 inwall is provided with friction plate and upper surface is connected with circular hollow rotating disk 14, and increasing friction force makes interior
Portion's workpiece is more firm, and rotating disk makes main mould 2 rotary work, and part compacting is more well-balanced, is provided with evanohm inside described low punch 3
Spring 5, high temperature resistant, rigidity is big, life-span length, is furnished with shears 6 in described cut-off-die 7, and described shears 6 one end connects stretches out outside cut-off-die 7
Long nut, control the shears time of staying, it is short to unclamp the time of staying, it is long to shorten the then time of staying, described upper punch 8 works bread
Wrap up in smooth crash roll 15, reduce rigid contact protection processing part and increase the service life, described screw plate 12 is worked by two pieces
