Abstract
The present invention relates to a kind of process for stamping of sheet metal, it includes heating pending sheet metal, and coat 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 it is pre-chilled, and is 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 mold, punching press is carried out by the pressure-activated dynamic compressor of setting.The principle that present invention utilization is expanded with heat and contract with cold, pending sheet metal is first heated and coat specific applicator A, then cools down and coat specific applicator B again, to overcome the problems, such as rhegma or cut occur during existing metallic plate punching.
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 its process for stamping.Currently, when implementing punch process to sheet metal, often it is easy out
The phenomenon that existing rhegma or cut.How to overcome this phenomenon that metallic plate punching process occurs at current metallic plate punching
Technology is badly in need of the technical issues of solving.
Invention content
The purpose of the present invention is to provide a kind of process for stamping of sheet metal, it can solve existing metallic plate punching
Occurs the problem of rhegma or cut in the process.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
It includes 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；Its
In, the applicator A is mixed by following parts by weight：30 parts~40 parts of lube base oil, Petropols be 5 parts~
0.5 part~1 part of 10 parts, 1 part~5 parts of ox-hide cream and magnesium silicate；
B. it will be cooled to 0 DEG C~5 DEG C in advance by the sheet metal of step A processing, then coat one layer of coating on its surface again
Object B；Wherein, the applicator B is mixed by following parts by weight：30 parts~40 parts of lube base oil, Petropols
For 0.5 part~1 part of 5 parts~10 parts, 1 part~5 parts of clay and silica；
C. it will be put into mold by the sheet metal of step B processing, punching press carried out by the pressure-activated press 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 and is coated specific applicator A by the present invention using the principle expanded with heat and contract with cold,
Then it cools down again and coats specific applicator B, and so that the surface of sheet metal is fully absorbed above-mentioned coating by the above way
Object A and applicator B, and make to have the function of interpenetrating between applicator A and applicator B, to overcome existing metallic plate
Occurs the problem of rhegma or cut in material punching course；In addition, relatively strong due to being respectively provided in above-mentioned applicator A and applicator B
Adhesive force so that sheet metal is not in the phenomenon that dispersing in punching course.
Specific implementation mode
Below in conjunction with specific embodiment, the invention will be further described, and protection scope of the present invention is not only limited to
