A kind of blanking blanking die of aluminum alloy plate materials
Technical field
The present invention relates to machining equipment field, the blanking blanking die of more particularly to a kind of aluminum alloy plate materials.
Background technology
Punching is make that portion of material or process part processing detach with another part material, work (sequence) part or waste material using punch die one
Kind stamping procedure.Punching is that shearing, blanking, punching, punching lack, jet-bedding, cutting, chisel are cut, trimming, cut the separation such as tongue, incision, trimming
The general name of process.The part of shape and size or the process for stamping of blank needed for being isolated from plate.Punching is to utilize punch die
Cutting edge plate is made to generate shear-deformable along certain contour line and is detached.It is maximum to be punched shared ratio in punching production.
In blanking process, in addition to the metal near shearing contour line, plate does not generate plastic deformation in itself, so being punched by tablet
The part of processing is still a flat shape.
In blanking die, most important structural parameters are exactly blade clearance.The offset of the upper and lower mould edge mouth of blanking die
Referred to as gap.Gap has an impact quality, the Life of Punch Die of shear-deformable, destructive process, blanking part.Blade clearance is by plate
Performance, sheet thickness, punching mode and punch die structure etc. many factors influence, and general unilateral gap takes the 10 ~ 15% of plate thickness.
In addition, at present for the punching of workpiece generally using placing and taking out manually, so due to the danger of blank operation
Property so that manual feeding, feeding have very big potentially danger.
In addition, the case hardness due to aluminium alloy is high not as steel surface hardness so that it holds in blanking process
Aluminium skimmings are also easy to produce, the installation of machining position is caused to deviate, so as to cause the error of processing dimension.In addition, due to aluminum alloy surface
Hardness is not very high, and the scuffing of workpiece surface is be easy to cause in blanking process, so as to influence the surface smoothness of workpiece.
In addition, for the punch press process of aluminum alloy materials, often due to the material of aluminum alloy materials is softer, it is being punched
During process, since cavity plate is hollow, so when punch-pin moves down under pressure, aluminum alloy materials compression position due to
The impact force of pushing is received suddenly so that aluminum alloy materials are deformed, and influence appearance and processing dimension.
In addition, aluminium alloy punching mold, one set of die can only be directed to a kind of product of shape specification size at present, for
Some yield are smaller or product specification changes more product, when carrying out the processing of blanking die, often due to the system of mold
It causes excessively high, and selects other manufacturing process, so others manufacturing process can not replace punch press process means well
The advantages of.
