Stainless Steel 304 Stainless Steel Bending Service Stainless Steel Bracket
Stainless steel bending Service instroduction
At Qingdao yonglihao, we use various stainless steel bending methods to manufacture our products. We provide in-house stainless steel rolling capabilities through the following methods:
The large-radius bending stainless steel rolls on a profile bending machine (also called a profile bending machine or angle steel roll).
Bending stainless steel that requires a bending radius is rolled on a rotary stretch-bending machine using a technique called mandrel bending.
Rolled stainless steel pipes or steel pipes that require bending and minimum wall thickness or elliptic deformation will be rolled using induction bending.
A CNC 4-roll bending machine can be used for spiral spiral bending on any stainless steel profile.

what is stainless steel bending service?
If the stainless steel bending service radius is smaller than the thickness of the material, a punch with a radius at the front end smaller than the thickness of the material must be used, and resort to the imprint bending method. In this way, it requires 10 times the pressure of free stainless steel bending services.
As far as free stainless steel bending services is concerned, the punch and die are processed at 85 ° or less (smaller is better). When using this set of molds, pay attention to the gap between the punch and the concave mold at the bottom of the stroke, and enough to compensate for the springback and keep the material bent excessively about 90 °.
Generally, the springback angle of a free bending die on a new bending machine is ≤2 °, and the bending radius is equal to 0.156 times the opening distance of the die.
For bottomed concave mold bending, the mold angle is generally 86 ~ 90 °. At the bottom of the stroke, there should be a gap between the male and female dies slightly larger than the thickness of the material. The forming angle is improved because the tonnage of the bottomed die is larger (about 4 times that of free bending), which reduces the stress that usually causes springback within the stainless steel bending services radius.
The embossing stainless steel bending services is the same as the bending of the bottomed concave mold, except that the front end of the punch is processed to the required bending radius, and the gap between the convex and concave molds at the bottom of the stroke is less than the material thickness. Due to the application of sufficient pressure (about 10 times of free bending) to force the front end of the punch to contact the material, springback is basically avoided.
In order to select the lowest tonnage specification, it is best to plan for a bending radius greater than the thickness of the material, and use the free stainless steel bending services method as much as possible. When the bending radius is large, it often does not affect the quality of the finished part and its future use.
Curved stainless steel applications
Curved stainless steel is often used for handrails, bollards, ladders, stairs and sculptures. Recently, stainless steel bending has begun to replace concrete in structural design, including swimming pools. Specialized containers, such as fermentation tanks for brewing and craft beer, as well as pharmaceutical and food-grade applications, often use curved stainless steel pipes as piping systems for conveying fluids.
