Abstract
The present invention relates to a kind of process for stamping of sheet metal, it includes heating pending sheet metal, and coats one layer of applicator A being mixed by following parts by weight：30 parts~40 parts of lube base oil, Petropols are 5 parts~10 parts, 0.5 part~1 part of 1 part~5 parts of ox-hide cream and magnesium silicate；Then precooling, and coating one layer of applicator B being mixed by following parts by weight again：30 parts~40 parts of lube base oil, Petropols are 5 parts~10 parts, 0.5 part~1 part of 1 part~5 parts of clay and silica；Sheet metal is put into mould, punching press is carried out by the pressure-activated dynamic compressor of setting.Pending sheet metal is first heated using the principle expanded with heat and contract with cold and coats specific applicator A, then cooled down again and coat specific applicator B, so that the problem of rhegma or cut occur during overcoming existing metallic plate punching by the present invention.
Description
Technical field
The present invention relates to mechanical spare and accessory parts processing technique field, especially a kind of sheet metal.
Background technology
It is more and more extensive with the application of sheet metal, and the quality of sheet metal and its process for stamping are closely related, because
This, people also increasingly pay close attention to for its process for stamping.At present, when implementing punch process to sheet metal, often easily go out
The phenomenon of existing rhegma or cut.How this phenomenon that metallic plate punching process occur is overcome into current metallic plate punching
Technology is badly in need of the technical problem solved.
The content of the invention
It is an object of the invention to provide a kind of process for stamping of sheet metal, it can solve existing metallic plate punching
During the problem of there is rhegma or cut.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
It comprises the following steps：
A. pending sheet metal is heated to 50 DEG C~60 DEG C, then coats one layer of applicator A on its surface；Wherein, institute
Applicator A is stated to be mixed by following parts by weight：30 parts~40 parts of lube base oil, Petropols be 5 parts~10 parts,
0.5 part~1 part of 1 part~5 parts of ox-hide cream and magnesium silicate；
B. the sheet metal handled by step A is cooled to 0 DEG C~5 DEG C in advance, then coats one layer of applicator B on its surface again；
Wherein, the applicator B is mixed by following parts by weight：30 parts~40 parts of lube base oil, Petropols are 5 parts
0.5 part~1 part of~10 parts, 1 part~5 parts of clay and silica；
C. the sheet metal handled by step B is put into mould, punching press is carried out by the pressure-activated dynamic compressor of setting.
By adopting the above-described technical solution, the present invention has following remarkable result compared with prior art：
Pending sheet metal is first heated using the principle expanded with heat and contract with cold and coats specific applicator A, then by the present invention
Cool down again and coat specific applicator B, and by above way make the surface of sheet metal fully absorb above-mentioned applicator A and
Applicator B, and make that there is the effect interpenetrated between applicator A and applicator B, so as to overcome existing metallic plate punching
During the problem of there is rhegma or cut；In addition, due to having stronger attachment respectively in above-mentioned applicator A and applicator B
Power so that sheet metal is not in the phenomenon dispersed in punching course.
