How many steps are required to stretch the product of an electric water heater? The stretching height and size of each step are calculated by the stretching coefficient. The stretching structure and process are different, and the stretching system is also different, so it is necessary to make a reasonable choice according to the actual product.
The main factors affecting the stretch coefficient:
1. Material mechanical properties (yield strength-elastic deformation; tensile strength-plastic deformation; elongation coefficient; reduction of area).
2. The relative thickness of the material.
3. Stretching times.
4. Stretching method.
5. The corner radius of the convex and concave molds.
6. The smoothness and lubrication conditions, gaps, etc. of the stretched working surface.
7. Stretching speed.

Basic knowledge
1. Bulging
Bulging is a stamping process in which hollow or tubular parts are expanded radially outward. Sectioning Sectioning is a stamping process that divides the forming process into several pieces.
2. Leveling
Leveling is a stamping process to improve the flatness of partial or overall planar parts.
3, ups and downs forming
It is a stamping process that relies on the extension of the material to form partial depressions or protrusions in the process parts. The change of material thickness in the undulating forming is unintentional, that is, a small amount of change in thickness is formed naturally during the deformation process and is not a requirement specified by the design.
4. Bending
Bending is a stamping process that uses pressure to produce plastic deformation of the material, thereby being bent into a shape with a certain curvature and a certain angle.
