2. Stainless steel processing bending in the unit size, the greater the tensile strength, then the smaller the elongation, so the greater the bending effort required, the greater the bending angle will be.
3. If the design drawings in the stainless steel plate thickness and bending radius corresponds to the case, according to Hangzhou stainless steel Jiaqi stainless steel experience, a bending workpiece should be unfolded for the right-angled edge of the size of the sum minus the two plate thicknesses, so that the design can fully meet the accuracy requirements.
4. The yield strength of stainless steel material, if the greater, then the greater the elastic recovery, if you can get the angle of 90 degrees of the bent parts, then the angle of the required pressure knife should be designed the smaller.
There are currently two methods on the market for stainless steel tubes to get a curved shape
One, cold bending method: generally use the bending machine many times rolling molding,
Disadvantages are: 1, the diameter of the steel tube is limited, generally only between 1CM-5CM
2, such as bending is too small, prone to deformation of the diameter of the steel tube
Two, hot bending method: Stainless steel tube filled with sand, add full, high-temperature heat treatment bending, this method is the most ideal;
Disadvantages are: the cost is too high, the cost is large, not suitable for synthetic batch production.
