Abstract
The utility model discloses a kind of one of radially inner ring finishing die of thin wall cylinder inwall, it collectively constitutes vertical axial fit mould by core, cylinder mould, die sleeve and bed die.Overcoat die sleeve constitutes cast outer mold structure on the bed die, and built-in core is by small end shoulder and the axial counterbore location fit of bed die, and core small end height of shoulder is more than the axial counterbore depth of bed die, and both dimension differences are equal to workpiece built-in radial inner ring thicknesses.The cylinder mould is axially inserted between core along die sleeve endoporus and reserved in die cavity, and pressure cylinder mould constitutes the upsetting squeeze structure to built-in workpiece downwards.The utility model realizes that the step upsetting extrusion of workpiece inner wall radially inner ring one is processed by mould upsetting squeeze, and most important is that workpiece had both retained the original fiber of metal material after upsetting squeeze, makes tissue finer and close again, therefore product strength is high, rigidity foot.The utility model belongs to cold upsetting extrusion mould, using a step upsetting extrusion technique, and production efficiency is high, is particularly suitable for mass production applications.
Description
Technical field
The utility model is related to a kind of technology in metal forming field, and specifically, the utility model is related to one kind
Upsetting extrusion mould, particularly a kind of one of radially inner ring finishing die of thin wall cylinder inwall.
Background technology
Thin-wall barrel belongs to the part of conventional structure, and application scenario is a lot.Under prior art conditions, for making inwall
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 the major class of casting forming process two.
It is at most machine cut forming technology that current manufacturing industry, which is applied, and blank can obtain expected precision size through machine cut processing
And form and position 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, cause 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, its deficiency is that production efficiency is low, and the machinery of metal material
Performance indications are relatively low, and it is supporting that the product being made can only be adapted to general occasion.The part majority of automobile accessories thin-wall barrel is in biography
The position of torque delivery,, should with greater need for there is enough intensity and rigidity for these position auxiliary equipments in addition to the precision for requiring higher
The product being made of existing machine cut and casting forming process not exclusively reaches automobile accessories requirement.
Utility model content
The thin wall cylinder that the utility model is manufactured mainly for machine cut and casting forming process is not suitable for automobile accessories and asked
Topic, proposes a kind of one of radially inner ring finishing die of thin wall cylinder inwall of supporting upsetting extrusion technique, and the mode structure is simple, stress is closed
Manage, the demoulding is easy, forming quality is good.
The utility model is achieved through the following technical solutions technical goal.
One of radially inner ring finishing die of thin wall cylinder inwall, it collectively constitutes vertical axial direction by core, cylinder mould, die sleeve and bed die
Cover matched moulds.The die sleeve is cylindrical structural member, and bottom face and endoporus press workpiece blank outer wall shape and the preset shaping of size.It is described
Bed die is in flange-like member, and the preset axial counterbore of boss upward, bed die overcoat die sleeve constitutes cast outer mold structure.Its improvements exists
In：The core is a coaxial evagination shoulder shaft part of section, and big end outside diameter upward is equal to workpiece blank diameter of bore, down
The axial counterbore location fit of small end shoulder and bed die, core small end height of shoulder directed downwardly is more than the axial counterbore depth of bed die,
Both dimension differences are equal to workpiece built-in radial inner ring thicknesses, and core small end shoulder diameter directed downwardly is equal to workpiece diameter to inner ring
Internal diameter.The cylinder mould is axially inserted into along die sleeve endoporus until cooperatively forming reserved die cavity with core, and press downwards cylinder mould structure
The upsetting squeeze structure of workpiece built in pairs.
In said structure, preset axial counterbore is flat circular hole, axial counterbore and core small end directed downwardly on the bed die
Shoulder gap coordinates.
The utility model compared with prior art, has the positive effect that：
1st, the tooling structre of axial fit is simple, make easy；
2nd, workpiece blank is processed through upsetting squeeze, has both retained the original fiber of metal material, makes tissue finer and close again, the production being made
Product intensity is high, rigidity is good；
3rd, workpiece is by upsetting extrusion, and follow-up amount of machining is very few, and stock utilization is high；
4th, workpiece is through a step upsetting extrusion, and production efficiency is high.
Brief description of the drawings
Fig. 1 is the structural profile schematic diagram before the utility model does not press.
Fig. 2 be in Fig. 1 workpiece 5 by the structural profile schematic diagram after upsetting squeeze.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
One of radially inner ring finishing die of thin wall cylinder inwall shown in the drawings, it is total to by core 1, cylinder mould 2, die sleeve 3 and bed die 4
With the vertical axial fit mould of composition.The die sleeve 3 is cylindrical structural member, bottom face and endoporus by the blank outer wall shape of workpiece 5 and
The preset shaping of size.The bed die 4 is in flange-like member, and the preset axial counterbore of boss upward, the overcoat die sleeve 3 of bed die 4 is constituted
Cast outer mold structure.The core 1 is a coaxial evagination shoulder shaft part of section, and big end outside diameter upward is equal to the blank endoporus of workpiece 5
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 coordinates with the small end shoulder gap directed downwardly of core 1.In addition, the small end height of shoulder directed downwardly of core 1 is big
In the axial counterbore depth of bed die 4, both dimension differences are equal to workpiece and built-in radial inner ring thicknesses.The small end stand directed downwardly of core 1
Shoulder diameter is equal to the internal diameter of the built-in radial inner ring of workpiece 5.The cylinder mould 2 is axially inserted into along the endoporus of die sleeve 3 until matching somebody with somebody with core 1
Close and form reserved die cavity, pressure cylinder mould 2 constitutes the upsetting squeeze structure to built-in workpiece 5 downwards.Workpiece 5 is become by plasticity is produced after upsetting squeeze
Shape, excess metal material, which is extruded between core 1 and the end face of bed die 4, reserves gap, and the metal material of press-in is directly formed
The inwall radially inner ring of workpiece 5.The utility model realizes that the inwall radially inner ring one step forming of workpiece 5 is processed by mould upsetting squeeze, by
In die forming high precision, seldom, stock utilization is high for follow-up amount of machining.Most important is that workpiece 5 both retained after upsetting squeeze
The original fiber of metal material, makes tissue finer and close again, therefore product is higher than prior art intensity, rigidity is good, fully meets automobile
It is supporting to require.The utility model belongs to cold-extrusion shaping mould, using a step upsetting extrusion technique, and production efficiency is high, is particularly suitable for
Mass production applications.
