Deep Drawing Process Parameters

The precision deep drawing process under continuous die requires reasonable setting of process parameters to ensure the quality and dimensional accuracy of the finished product. The following are several commonly used process parameters:

1. Tensile force: Tensile force refers to the magnitude of stress applied to a metal sheet. The magnitude of tensile force is related to factors such as the material properties, size, and stretching speed of the metal sheet. Excessive tensile force can cause the metal sheet to fracture, while insufficient tensile force can result in uneven stress.

2. Deep drawing speed: Stretching speed refers to the speed at which a metal sheet is stretched during the stretching process. The selection of stretching speed should be determined based on the properties and shape of the metal sheet. Excessive stretching speed can easily lead to stress concentration and excessive heating, while slow stretching speed can reduce production efficiency.

3. Deep drawing time: Stretching time refers to the duration of the metal sheet during the stretching process. The length of stretching time affects the strain and stress distribution of metal sheets. Excessive stretching time can lead to excessive stretching and loss of elasticity of the metal sheet, while too short stretching time can affect the dimensional accuracy of the finished product

4. Mold gap: The mold gap is the distance between the upper and lower molds. The size of the gap should be determined based on the thickness and material properties of the metal sheet. Excessive mold clearance can lead to oversized finished products, while insufficient mold clearance can result in poor surface quality.

By setting the above process parameters reasonably, the stability and quality control of the precision deep drawing process under continuous die can be ensured, thereby obtaining high-precision and high-quality stretching products.
