Abstract
The invention discloses a kind of metallic plate punching methods, include the following steps, step 1 provides mold, according to the shape of stamping parts, manufacture and design mold；Stamping die is set on stamping equipment by step 2；Step 3 configures metal plate, selects suitable pressed sheet according to the needs of stamping parts；Metal plate is placed in stamping station by step 4, and is fixed by the clamping part on press machine；Step 5 carries out punching press to metal plate to by formed punch by pressing process, metal plate is made to be formed down the pressing piece with depth；The good product of punching press is placed on designated position by step 6.Metallic plate punching method process of the invention is few, environmental pollution is few, high production efficiency, can stamp out the higher stamping parts of flatness.
Description
Technical field
The present invention relates to a kind of stamping technology fields, are especially a kind of metallic plate punching method.
Background technique
Stamping die is equipped a kind of special process that material is processed into part, referred to as cold punching in Cold Press Working
Compression mould.Punching press, be at room temperature, using the mold being mounted on press machine to material apply pressure, make its generate separation or
Plastic deformation, thus a kind of pressure processing method of part needed for obtaining.
There is following impact due to gasket by formed punch in existing gasket stamping die, gasket exists certain
Arch upward, and gasket in stamping die there is no flattening, after the completion of gasket punching press, entire gasket is not flat enough
It is whole.
Usually when implementing punch process to sheet metal, to prevent rhegma or scratch, during punch forming
Lubricating oil need to be coated in metal sheet surface to improve lubricity and processability.When using lubricating oil, in addition to due to oil dispersing and
Deteriorate working environment outer, some researches show that, it is this shape after product, it is used with chlorine system when washing punching oil
Based on the evaporation of organic solvent seriously pollute environment.For prevent punching oil from dispersing or detergent evaporation and caused by environment it is dirty
Dye problem is also needed using organic solvents such as dimethylbenzene, toluene, cyclohexanones sometimes, and more, expense that there are processes pays big, pollution ring
The problems such as border.Simultaneously there is painting process in either which kind of method, influence processing efficiency, increase production cost.
Summary of the invention
Goal of the invention: in order to solve the problems, such as punching press out-of-flatness, the present invention provides a kind of metallic plate punching methods.
Technical solution:
A kind of metallic plate punching method, includes the following steps,
Step 1 provides mold, according to the shape of stamping parts, manufactures and designs mold；
Stamping die is set on stamping equipment by step 2；
Step 3 configures metal plate, selects suitable pressed sheet according to the needs of stamping parts；
Metal plate is placed in stamping station by step 4, and is fixed by the clamping part on press machine；
Step 5 carries out punching press to metal plate to by formed punch by pressing process, and being formed down metal plate has deeply
The pressing piece of degree；
The good product of punching press is placed on designated position by step 6.
Further, plastic film is covered on sheet metal in step 4.
Further, plastic film described in step 4 is 50 microns to 300 microns.
Further, punching press is carried out by the pressure of setting in step 5.
Further, when formed punch is to mold bottommost in step 5, the spacing of formed punch and mold is equal to the thickness of stamping parts.
Further, the pressure in step 5 between formed punch and mold is 1.2Mpa or more.
The utility model has the advantages that metallic plate punching method process of the invention is few, environmental pollution is few, high production efficiency, can rush
Extrude the higher stamping parts of flatness.
Specific embodiment
Invention is further described in detail below.
A kind of metallic plate punching method, includes the following steps,
Step 1 provides mold, according to the shape of stamping parts, manufactures and designs mold；
Stamping die is set on stamping equipment by step 2；
Step 3 configures metal plate, selects suitable pressed sheet according to the needs of stamping parts；
Metal plate is placed in stamping station by step 4, and is fixed by the clamping part on press machine；
Step 5 carries out punching press to metal plate to by formed punch by pressing process, and being formed down metal plate has deeply
The pressing piece of degree；
The good product of punching press is placed on designated position by step 6.
Preferably, plastic film is covered on sheet metal in step 4.
Preferably, plastic film described in step 4 is 50 microns to 300 microns.
Preferably, punching press is carried out by the pressure of setting in step 5.
Preferably, when formed punch is to mold bottommost in step 5, the spacing of formed punch and mold is equal to the thickness of stamping parts.
Preferably, the pressure in step 5 between formed punch and mold is 1.2Mpa or more.
Metallic plate punching method process of the invention is few, environmental pollution is few, high production efficiency, can stamp out flatness
Higher stamping parts.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, several improvement can also be made, these improvement also should be regarded as of the invention
Protection scope.
