Abstract
The utility model discloses a kind of valve screw extrusion dies, and including cavity plate and punch-pin, the cavity plate is made of cavity plate outer ring and the die plate insert being fitted in cavity plate outer ring, and forming hole is provided in die plate insert；The punch-pin is formed by the punch case that is fitted in punch-pin trim ring and in punch case and with the punch insert of punch case clearance fit, and the outer diameter of punch case and the maximum inner diameter of forming hole coordinate.The cavity plate and punch-pin of the utility model using modular construction, can reduce stress concentration, mold uniform force, mold fracture is can effectively prevent, greatly improves the service life of mold, and after mold one of parts damages, it still can be continuing with after replacement, it is cost-effective.
Description
Technical field
The utility model is related to a kind of valve screw extrusion dies, belong to cold extrusion processing technique field.
Background technology
Cold-extrusion technology technology belongs to metal material precision plastic forming technology.With the Principles of Plastic Molding of metal,
Under forcing press effect, cylinder blank cold-extrusion shaping in a mold compared with cylinder bar part machined after forming is directly used, passes through
Not only mechanical property is preferable for the extrusion of Plastic Forming, and cold-extruded part can obtain valve screw zero through a small amount of mechanical processing
Part is a kind of " section material " near-net-shape new process.
Generally using punch-pin and cavity plate cooperation come cold-extrusion shaping part in existing technology, but punch-pin and cavity plate are shaping
During metal parts, the resistance of deformation being subject to is big, and the stress that mold is born is big, easily cracked on punch-pin and cavity plate or
Person's notch leads to not use, and the service life is shorter.
Utility model content
The purpose of this utility model is to provide it is a kind of it is simple in structure, easy to assembly, be conveniently replaceable, service life it is longer
Valve screw extrusion die, to overcome deficiency of the prior art.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme：A kind of valve screw extrusion die,
Including cavity plate and punch-pin, the cavity plate is made of cavity plate outer ring and the die plate insert being fitted in cavity plate outer ring, in die plate insert
It is provided with forming hole；The punch-pin is by the punch case that is fitted in punch-pin trim ring and in punch case and and punch case
The punch insert of clearance fit is formed, and the outer diameter of punch case and the maximum inner diameter of forming hole coordinate.
Further, 10~15mm of lower end of punch case is stretched out in the lower end of the punch insert.
Further, the gap width between the punch case and punch insert is 0.02~0.04mm.
Further, the forming hole is three-level stepped hole, and the stepped hole of top is hexagonal hole, bottom two-stage step hole
For circular hole, and bottommost stepped hole is penetrated through with jogger hole, and mandril, the lower end of mandril and angled slide block are slidably connected in jogger hole
Contact.
Compared with prior art, the utility model has the advantage of：The cavity plate and punch-pin of the utility model are using assembling
Formula structure can reduce stress concentration, and mold uniform force can effectively prevent mold fracture, greatly improve the service life of mold,
And after mold one of parts damages, still can be continuing with after replacement, it is cost-effective.

Specific embodiment
It is new to this practicality with reference to embodiment in order to make the utility model aim, technical solution and advantage clearer
Type is described in further detail.
The embodiment of the utility model：The structure diagram of the valve screw extrusion die of the utility model is as shown in Figure 1, bag
Cavity plate and punch-pin are included, the cavity plate is made of cavity plate outer ring 1 and the die plate insert being fitted in cavity plate outer ring 12, in die plate insert 2
Inside it is provided with forming hole 8, during making, die plate insert 2 uses material W6Mo5Cr4V2, and cavity plate outer ring 1 uses 45 steel, is ensureing mold
Mold materials expense is substantially reduced while intensity, reduces die cost；The punch-pin is by being fitted in punch-pin trim ring 3
Punch case 4 and formed in the punch case 4 and with the punch insert 5 of 4 clearance fit of punch case, the outer diameter of punch case 4 with into
The maximum inner diameter cooperation of type hole 8.The lower end 14mm of punch case 4 is stretched out in the lower end of the punch insert 5.The punch case 4 and punch-pin
Gap width between core 5 is 0.03mm.The forming hole 8 is three-level stepped hole, and the stepped hole of top is hexagonal hole, bottom
Two-stage step hole is circular hole, and bottommost stepped hole is penetrated through with jogger hole, and mandril 6 is slidably connected in jogger hole, mandril 6
Lower end is contacted with angled slide block 7.
In use, punch assemblies are fixed on by connector on the cope plate of four guide pole die carriers first and are lived with forcing press
Dynamic crossbeam downlink, cavity plate component is fixed on fixed on press machine lower die seat by blank holder and connector.Cylindrical bar
Expect to be put into forming hole 8 after lubrication, pre-patterned male mold presses downwards, under pressure shape through phosphorating treatment of annealing after blanking
Into the prefabricated blank with hexagonal.Prefabricated blank annealed phosphorating treatment again, cavity plate is constant, replaces and is extruded into shape punch assemblies, punch set eventually
Part downlink presses to hexagon prefabricated blank, controls punch assemblies downward storke, final to obtain required valve screw extrusion.It squeezes
At the end of, under the drive of jacking cylinder of hydraulic press, angled slide block 7 withstands mandril 6 and moves upwards upwards, ejects extrusion.
