From the perspective of the hardware industry, stamping parts belong to professional hardware processing with strict processing requirements. Precision metal stamping parts can be directly made into flat parts, or prepared for other stamping processes such as bending, drawing, forming, etc., or cut and trim on formed stamping parts. Blanking is widely used in automobile, household appliances, electronics, instrumentation, machinery, railway, communications, chemical industry, light industry, textile, aerospace and other industrial sectors. The blanking process accounts for 50%~60% of the whole stamping process.
Processing of precision metal stamping parts
The processing of precision metal stamping parts is mainly divided into two categories: separation process and deformation process. The separation process is a stamping processing method that can separate the stamping parts and sheet materials along the required contour line and obtain a certain section quality; Deformation process is a kind of stamping processing method which can make the blank plastic deformation without damage to obtain the required shape, size and accuracy. There are two kinds of stamping temperature: cold stamping and hot stamping. This depends on the strength, plasticity, thickness, deformation degree and equipment capacity of the material, and the service conditions of the original heat treatment state of the material shall be considered. The simple stamping die is divided into cold stamping and hot stamping. The simple stamping die is a process that only completes the stamping die in one stroke. When working, the strip is fed between two guide plates on the die until it touches the locating pin.
