Abstract
The invention discloses a kind of one of radially inner ring finishing dies of thin wall cylinder inner wall, it collectively constitutes vertical axial fitting mould by core model, cylinder mould, die sleeve and bed die.Housing die sleeve constitutes cast outer mold structure on the bed die, and for built-in core model by small end shoulder and bed die axial direction counterbore location fit, core model small end height of shoulder is more than bed die axial direction counterbore depth, and difference is equal to workpiece built-in radial inner ring thicknesses.The cylinder mould is axially inserted between core model along die sleeve endoporus and reserves in die cavity, and the cylinder mould that presses downwards constitutes the upsetting squeeze structure to built-in workpiece.The present invention realizes that one step upsetting extrusion of workpiece inner wall radially inner ring is processed by mold upsetting squeeze, and most important is that workpiece had not only retained the original fiber of metal material after upsetting squeeze, but also kept tissue finer and close, therefore product strength is high, rigidity foot.The invention belongs to cold upsetting extrusion moulds, and using a step upsetting extrusion technique, production efficiency is high, is particularly suitable for mass production applications.
Description
Technical field
The present invention relates to a kind of technologies in metal forming field, in particular it relates to a kind of upsetting extrusion
Mould, especially a kind of one of radially inner ring finishing die of thin wall cylinder inner wall.
Background technology
Thin-wall barrel belongs to the part of conventional structure, and there are many application scenario.Under prior art conditions, for making inner wall
It is equipped with radially inner ring and the thin-wall barrel technique of wall thickness not etc., mainly there is shaping by stock removal technique and casting forming process two major classes.
It is machine cut forming technology that current manufacturing industry, which is applied at most, and expected precision size can be obtained through machine cut processing in blank
And geometric tolerance.But machine cut forming technology except cutting output greatly in addition to, stock utilization is also very low, maximum deficiency be gold
Belong to the original fibr tissue of material by artificial destruction, causes the mechanical performance and mechanical properties decrease of product.Casting forming process
Implement relative ease, the follow-up machining amount of blank cast is few, and deficiency is that production efficiency is low, and the machinery of metal material
Performance indicator is relatively low, and manufactured product can only be suitble to general occasion mating.The component majority of automobile accessories thin-wall barrel, which is in, to be passed
It, with greater need for having enough intensity and rigidity, is answered for these position auxiliary equipments in addition to more demanding precision at the position of torque delivery
The product made of existing machine cut and casting forming process not exclusively reaches automobile accessories requirement.
Invention content
The thin wall cylinder manufactured present invention is generally directed to machine cut and casting forming process is not suitable for automobile accessories problem, carries
Go out a kind of one of radially inner ring finishing die of thin wall cylinder inner wall of mating upsetting extrusion technique, the mode structure is simple, reasonable stress, takes off
Mould is easy, forming quality is good.
The present invention is achieved through the following technical solutions technical goal.
One of radially inner ring finishing die of thin wall cylinder inner wall, it collectively constitutes vertical axial direction by core model, cylinder mould, die sleeve and bed die
Set molding.The die sleeve is cylindrical structural member, and bottom face and endoporus press workpiece blank outer wall shape and the preset forming of size.It is described
Bed die is in flange-like member, and the preset axial counterbore of boss upward, bed die housing die sleeve constitutes cast outer mold structure.Its improvements exists
In：The core model is a coaxial evagination shoulder shaft part of section, and big end outside diameter upward is equal to workpiece blank diameter of bore, downward
Small end shoulder and bed die axial direction counterbore location fit, core model small end height of shoulder directed downwardly is more than bed die axial direction counterbore depth,
Both matched axial dimension difference is equal to workpiece built-in radial inner ring thicknesses, and core model small end shoulder diameter directed downwardly is equal to work
The internal diameter of radially inner ring in part.The cylinder mould is axially inserted into along die sleeve endoporus until with core model cooperatively form reserved die cavity, to
Lower pressure cylinder mould constitutes the upsetting squeeze structure to built-in workpiece.
In above structure, preset axial direction counterbore is flat circular hole, axial counterbore and core model small end directed downwardly on the bed die
Shoulder clearance fit.
Compared with prior art, the present invention having the positive effect that：
1, the tooling structre of axial fitting is simple, is easy to make；
2, workpiece blank is processed through upsetting squeeze, has not only retained the original fiber of metal material, but also keep tissue finer and close, manufactured production
Product intensity is high, rigidity is good；
3, for workpiece by upsetting extrusion, follow-up amount of machining is very few, and stock utilization is high；
4, for workpiece through a step upsetting extrusion, production efficiency is high.
Description of the drawings
Fig. 1 is the structural profile illustration before the present invention does not press.
Fig. 2 be in Fig. 1 workpiece 5 by the structural profile illustration after upsetting squeeze.
Specific implementation mode
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.
One of radially inner ring finishing die of thin wall cylinder inner wall shown in the drawings, it is total to by core model 1, cylinder mould 2, die sleeve 3 and bed die 4
With the vertical axial fitting mould of composition.The die sleeve 3 is cylindrical structural member, bottom face and endoporus by 5 blank outer wall shape of workpiece and
The preset forming of size.The bed die 4 is in flange-like member, and the preset axial counterbore of boss upward, 4 housing die sleeve 3 of bed die is constituted
Cast outer mold structure.The core model 1 is a coaxial evagination shoulder shaft part of section, and big end outside diameter upward is equal to 5 blank endoporus of workpiece
Diameter, small end shoulder directed downwardly and the axial counterbore location fit of bed die 4.Axial counterbore preset on bed die 4 is in the present embodiment
Flat circular hole, axial counterbore and 1 small end shoulder clearance fit directed downwardly of core model.In addition, 1 small end height of shoulder directed downwardly of core model is big
In the axial counterbore depth of bed die 4, both matched axial dimension difference is equal to workpiece and built-in radial inner ring thicknesses.Core model 1
Small end shoulder diameter directed downwardly is equal to the internal diameter of 5 built-in radial inner ring of workpiece.The cylinder mould 2 is axially inserted into along 3 endoporus of die sleeve
Until cooperatively forming reserved die cavity with core model 1, the cylinder mould 2 that presses downwards constitutes the upsetting squeeze structure to built-in workpiece 5.Workpiece 5 is by upsetting
Plastic deformation is generated after squeezing, excess metal material reserves gap, the gold of indentation between being extruded to 4 end face of core model 1 and bed die
Belong to material and directly forms 5 inner wall radially inner ring of workpiece.The present invention by mold upsetting squeeze realize one step of workpiece 5 inner wall radially inner ring at
Shape is processed, and since die forming precision is high, follow-up amount of machining is seldom, and stock utilization is high.Most important is workpiece 5 through upsetting squeeze
Not only retained the original fiber of metal material afterwards, but also has kept tissue finer and close, therefore product is higher than prior art intensity, rigidity is good, completely
Meet automobile accessories requirement.The invention belongs to cold-extrusion shaping moulds, and using a step upsetting extrusion technique, production efficiency is high, especially
Application suitable for mass production.
