Description
Technical field
The utility model relates to a kind of swollen pattern tools of revolution sleeve, are suitable for the high-strength materials such as stainless steel, steel alloy
Type that sleeve is swollen.
Background technique
In sheet-metal formed field, it is lower small that currently used mould pressing mode is only suitable for shape of product required precision
Bulk article；Type that polyurethane rubber is swollen lower, simple shape small-sized swollen type of thin walled cylinder body suitable for the strength of materials；It is relatively advanced
Mode be hydroforming, but the technology the high requirements on the equipment, manufacturing process it is more troublesome and the service life is short.For the material having
Material intensity is big, shape is more complicated huge revolving sleeve member, such as stainless steel material, alloy steel material, and to guarantee batch at
Type, and can guarantee Product Precision, convenient for operation, save the cost, the still not no technology of comparative maturity at present.
Summary of the invention
The purpose of the utility model is to provide a kind of revolution sleeve molding die, meet that intensity is larger, complex-shaped conjunction
Gold is especially suitable for the forming of the high-strength materials such as stainless steel, high-temperature alloy steel, and mould and die accuracy, service life height, easy to operate, can be real
Now produce in batches, it is lower to equipment requirement, only common punch press is needed to can be realized.
The technical solution of the utility model is, the revolution sleeve molding die includes part of the upper die and part of the lower die,
The part of the upper die includes upper die holder, bullet top rubber, position-arresting disk, punch-pin, adjusting screw, and punch-pin is fixedly mounted on upper die holder
On, bullet top rubber is provided between position-arresting disk and upper die holder, adjusting screw passes through upper die holder and bullet top rubber and is fixed on limit
On disk, on the outside of the male bottom and the bottom inside of position-arresting disk is provided with the conical surface；Part of the lower die includes lower die holder, external mold
Block, internal module are provided with radial groove uniformly distributed at 8 on lower die holder, one group of outer mold piece and internal module, internal model are placed on each groove
It is provided with ejector pin between block and outer mold piece, spring is provided between internal module and ejector pin and between outer mold piece and ejector pin；External mold
Block includes outer mandrel and the outer swollen valve that is mounted in outer mandrel, and internal module includes inner axis of heart and is mounted on interior swollen on inner axis of heart
Valve, the outer swollen valve and interior swollen valve osculant face be turn round sleeve will at shape, the outside of outer swollen valve and interior swollen valve
Inside the conical surface, the conical surface and punch-pin and position-arresting disk cone match are set.
The utility model is required on common punch press using the shape and size of i.e. certifiable product, and consistency is good, behaviour
Make simple；It solves the product bulging of high-strength material and shape face complexity, is especially suitable for the high intensity such as stainless steel, high-temperature alloy steel
Material forming, product wall thickness may be up to 5mm or so；It is smaller, it can be achieved that batch production by discovery die wear is used for a long time；Mould
It is higher to have guiding accuracy, product uniform force when bulging reduces deflection conducive to the release of stress；It, can be anti-in Bulging Process
Multiple turnbarrel repeatedly molds bulging, can preferably guarantee the precision of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 molds status diagram when being utility model works；
Fig. 3 is molding work status magnified partial view；
Specific embodiment
As shown, revolution sleeve molding die includes part of the upper die and part of the lower die, the part of the upper die includes upper
Die holder 1, bullet top rubber 2, position-arresting disk 4, punch-pin 15, adjusting screw 17, punch-pin 15 are fixedly mounted on upper die holder 1, position-arresting disk 4 with
Bullet top rubber 2 is provided between upper die holder 1, adjusting screw 17 passes through upper die holder 1 and bullet top rubber 2 and is fixed on position-arresting disk 4,
The bottom inside of 15 bottom outside of punch-pin and position-arresting disk 4 is provided with the conical surface；Part of the lower die includes lower die holder 16, external mold
Block, internal module are provided with radial groove uniformly distributed at 8 on lower die holder 16, one group of outer mold piece and internal module are placed on each groove, interior
It is provided with ejector pin 11 between module and outer mold piece, is provided with bullet between internal module and ejector pin 11 and between outer mold piece and ejector pin 11
Spring；Outer mold piece includes outer mandrel 7 and the outer swollen valve 5 that is mounted in outer mandrel 7, internal module include inner axis of heart 12 and installation at heart
Interior swollen valve 10 on axis 12, the described outer swollen valve 5 and interior swollen 10 osculant face of valve be turn round sleeve will at shape, it is outer swollen
The conical surface, the conical surface and 4 cone match of punch-pin 15 and position-arresting disk is arranged in the outside of valve 5 and the inside of interior swollen valve 10.
When the utility model is used, blank material being put under mold open state between outer swollen valve 5, interior swollen valve 10；
The part of the upper die being made of under press machine drive upper die holder 1, bullet top rubber 2, position-arresting disk 4, punch-pin 15, adjusting screw 17 is whole
Move downward, outer swollen valve 5 under the conical surface effect of position-arresting disk 4 to contract, when on 4 inner cavity lower surface of position-arresting disk and outer swollen valve 5
When surface is bonded, outer swollen valve 5 be will no longer move, and the working surface of outer swollen valve 5 is the appearance profile size for turning round sleeve at this time；On
Mould part continues to move downward, and compresses bullet top rubber 2, interior swollen valve 10 expands outward under the conical surface effect of punch-pin 15, until upper
Die holder 1 is contacted with limited post 3, and thin-walled revolution workpiece blank is tightly clipped between outer swollen valve 5, interior swollen valve 10, and mold clamping terminates, this
When complete revolution sleeve forming.Under press machine drive, part of the upper die is moved upwards, and part of the lower die affranchises state.
