Abstract
The utility model discloses a shaping die for a high-proportion tungsten alloy ring, which is characterized by comprising an upper punch base plate, upper punches, die cores and a die carrier, wherein the upper punches are arranged on the upper punch base plate, and the die cores are arranged on the die carrier. The upper punches are complete outer upper punches; the die cores are complete outer die cores; the complete outer upper punches are respectively screwed into screwed holes of the upper punch base plate; the complete outer die cores are arranged on the die carrier through a swage block; and die cavities matched with the complete outer upper punches are respectively arranged in the complete outer die cores. The upper punches are complete inner upper punches; the die cores are complete inner die cores; the complete inner upper punches are respectively screwed into the screwed holes of the upper punch base plate; die cavities matched with the complete inner die cores are respectively arranged in the complete inner upper punches; and the die carrier is provided with a cylinder rod. In the high-proportion tungsten alloy ring shaping die disclosed by the utility model, certain operating steps are not needed, and the production efficiency is increased on the premise that the shaped tungsten alloy ring is ensured to be consistent in dimensional accuracy, the subsequent turning allowance of outside and inside diameters can be controlled to be within 0.5mm, and the material utilization rate is high.
Description
Technical field
The utility model relates to a kind of high-specific gravity tungsten alloy ring shaping mould, specifically a kind of stock utilization that can improve the high-specific gravity tungsten alloy ring and production efficiency, the high-specific gravity tungsten alloy ring shaping mould of simple in structure and good serviceability.
Background technology
For a long time, shaping process is usually used in the production of iron copper based articles in the powder metallurgy industry, and the mould of shaping is various naturally.And in the production of tungsten-Ni-Fe base-height ratio gravity tungsten alloy goods, process, because of the fusing point of tungsten is high, hard and crisp, how characteristics such as processing difficulties do not adopt the method for shaping to control the following process surplus, improve stock utilization.Common method is through optimum sintering technology, to constriction coefficient of high-specific gravity tungsten alloy product behind the sintering and groping of deflection, confirms the optimal parameter of required reservation allowance in the goods following process.Then existing high-specific gravity tungsten alloy ring shaping mould is a manual sizing die simple in structure, and a mould one of dash by whole internal mold, in whole, whole external mold, whole outwash being formed is towards the craft and the semi-automatic sizing die of formula.Though its structure is very simple, operating procedure is many, and during the inside and outside footpath of whole tungsten ring, at every turn can only a whole ring.Production efficiency is lower, causes the waste on the manpower and materials to company.
The utility model content
The purpose of the utility model provides a kind of stock utilization that can improve the high-specific gravity tungsten alloy ring and production efficiency, the high-specific gravity tungsten alloy ring shaping mould of simple in structure and good serviceability.
The purpose of the utility model realizes through following technical scheme:
A kind of high-specific gravity tungsten alloy ring shaping mould, it is characterized in that: said shaping mould comprises die head plate, Shang Chong, core rod and mould bases, goes up to dash to be installed on the die head plate, core rod is installed on the mould bases.
Said going up towards on outside whole, dashing, core rod is for putting in order outer core rod, and whole outer upward dashing is screwed in the screwed hole of die head plate, puts in order outer core rod and is installed on the mould bases through a pattern piece, and whole external mold in-core is provided with and puts in order the outer die cavity that matches that upward dashes.
Said go up dashing in whole dashed, and core rod is whole inner mould core, goes up to dash in whole to be screwed in the screwed hole of die head plate, wholely is provided with the die cavity that matches with whole inner mould core in dashing on interior, and mould bases is provided with a cylindrical rod.
The utility model compared with prior art has the following advantages.
The utility model has saved the certain operations step, and at the tungsten alloy ring dimensional accuracy high conformity that guarantees after shaping, the follow-up Vehicle Processing surplus of interior external diameter can be controlled in the 0.5mm, under the high prerequisite of stock utilization, has improved production efficiency.
Description of drawings
Fig. 1 is the whole profile die profile of the utility model high-specific gravity tungsten alloy ring;
Fig. 2 is the whole interior shape die profile of the utility model high-specific gravity tungsten alloy ring;
The profile of the whole outer core rod of Fig. 3;
The profile of the whole inner mould core of Fig. 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model high-specific gravity tungsten alloy ring shaping mould is described in further detail.
To shown in Figure 4, the described high-specific gravity tungsten alloy ring of the utility model shaping mould comprises die head plate 1, upward dashes 2, core rod 4 and mould bases 6, goes up towards being installed on the die head plate like Fig. 1, and core rod is installed on the mould bases.Put in order going up towards on outside whole, dashing of profile mould, core rod is for putting in order outer core rod, and whole outer upward dashing is screwed in the screwed hole of die head plate, puts in order outer core rod and is installed on the mould bases through a pattern piece 5, and whole external mold in-core is provided with and puts in order the outer die cavity that matches that upward dashes.Dash on the shape mould in whole in whole and dash, core rod is whole inner mould core, goes up to dash in whole to be screwed in the screwed hole of die head plate, wholely is provided with the die cavity that matches with whole inner mould core in dashing on interior, and mould bases is provided with a cylindrical rod 5.
In use, at first to frock and hydraulic press be coupled together.Backing plate is fixed on two clamping plates on the top board of hydraulic press, and two stampings then are screwed in two screwed holes on the stamping backing plate, indirect like this stamping and hydraulic press are coupled together.Hydraulic press upper and lower limit location point and rising or falling speed are set in advance, and stamping is up and down along with the up-down of hydraulic press core bar during work.The pattern piece is provided with two die cavitys, with stamping on same axis.Model block is fixed by bolts on the mould bases, replacing for convenience detach.The height of mould bases probably is ten height that tungsten ring 3 builds up, and makes things convenient for tungsten ring after the shaping in mould bases, to accumulate after certain quantity taking out and get final product, need not be whole one take out one and increase the repetition operation and move.In the whole inner mold, need not set up pattern and die cavity, only need fixing two cylindrical rods with holes on mould bases; Two core rod bases are inserted post rods upper end, whole in after the tungsten ring set on the post rod, build up certain altitude after; Core rod is taken away, will be encircled to take out in the post rod and get final product.Improved sizing die has simple in structure, processing ease, and the disassembling, assembling and replacing mould is convenient, has realized semi-automation basically, once can put in order the advantage of a plurality of workpiece.
