Stainless steel pipe bending processing method
Jul 18, 2022
1. If it is stainless steel plate processing, the thicker the unit size, then we need the greater the bending strength, but also with the thickness of the stainless steel plate increases, in the choice of bending equipment bending strength should also be greater.
2 stainless steel processing bending in unit size, the greater the tensile strength, then the elongation is smaller, so the required bending strength, bending Angle will be greater.
3. If the thickness of the stainless steel plate in the design drawing corresponds to the bending radius, according to the experience of Hangzhou stainless steel Jiaqi stainless steel, the expansion size of a bending workpiece should be the addition of the right Angle minus two plate thickness, so that it can fully meet the requirements of design accuracy.
4. If the yield strength of stainless steel is larger, the elastic recovery will be larger. If the bending Angle of 90 degrees can be obtained, the Angle of the press knife needed should be designed smaller.
There are 2 kinds of arc-shaped methods about stainless steel tube on the market
A, cold bending method: general bending machine for many times rolling molding,
The disadvantages are: 1, steel pipe diameter is limited, generally can only be between 1cm-5cm
2, such as bending is too small, easy to appear steel pipe diameter deformation
Two, hot bending method: stainless steel tube filled with sand, fill, high temperature heat treatment bending, this method is the most ideal;
Disadvantages are: the cost is too high, the cost is big, not suitable for synthetic batch production.
