Description
Technical field
The utility model, which is created, is related to blanking die, more particularly to a kind of aluminium alloy extrusions processing blanking die.
Background technology
Aluminium alloy is most widely used a kind of non-ferrous metal structural material in industry, in Aeronautics and Astronautics, automobile, machinery
Widely applied in manufacture, ship and chemical industry.The rapid development of industrial economy, to the demand day of Welded structural member
Benefit increases, and the Research on Weldability enabled aluminum alloy to is also goed deep into therewith.Aluminium alloy density is low, but intensity is higher, near or above excellent
Matter steel, plasticity is good, can be processed into various section bars, has excellent electric conductivity, thermal conductivity and corrosion stability, industrially widely uses,
Usage amount is only second to steel.
So-called punching, it is to make portion of material or process part processing and another part material, work (sequence) part or waste material point using punch die
From a kind of stamping procedure.Punching is that shearing, blanking, punching, punching are lacked, jet-bedding, cutting, chisel are cut, trimming, cuts tongue, incision, trimming
Deng the general name of separation circuit, the required part of shape and size or the process for stamping of blank are isolated from plate.Punching is profit
Plate is produced detrusion along certain contour line with the cutting edge of punch die and separate.It is punched shared ratio in punching production
It is maximum.In blanking process, in addition to the metal near shearing contour line, plate does not produce plastic deformation in itself, so by putting down
The part of plate punch press process is still a flat shape.
For the punch press process technique of aluminium alloy, because the material surface hardness of aluminium alloy does not have the case hardness of steel
Height, when being punched, easily aluminum alloy surface is scratched, influence outward appearance.Punch press process is all using upper solid convex at present
Mould, hollow cavity plate is engaged with, carries out the processing action of part.However, because the hardness of aluminum alloy material is not high, it is especially right
In the relatively thin parts of some sheet metal thicknesses, its when carrying out punch press process, often due to its to bear hardness not high, in upper male mould
When touching plate surface, sheet material is due to the impulsive force by upper male mould so that sheet material produces certain deformation, so as to influence zero
The crudy of part.
In addition, blanking die, after much time using is carried out, relative skew occurs for the position of upper male mould and lower punch,
Cause when carrying out punch press process, when upper male mould coordinates with lower cavity die, unilateral gap is inconsistent, causes the machining shape of part to be sent out
It is raw to change；Due to the increase or reduction in unilateral gap, the abrasion of upper male mould is caused to aggravate, and the burr after part processing increases
Add.
