Wrinkling treatment method for stainless steel tensile parts

Wrinkling treatment method for stainless steel tensile parts

一. Analysis of causes of wrinkles

1. Uneven pressure

In drawing processing, if the cutting speed is too fast or the machine tool processing is uneven, a slight extrusion force may be formed on the surface of the material, causing wrinkles.

2. Insufficient material strength

Wrinkling can also occur if the strength of the material is lower than required for stretching.

3. Mold design defects

Insufficient considerations in mold design or imperfect mold manufacturing processes may result in ripples and wrinkles.

二. How to deal with wrinkles of stainless steel tensile parts

1.Material selection

Choose better quality stainless steel flanges or steel pipes to ensure that the strength meets the requirements.

2. Optimize process parameters

Reasonably adjust the stretching processing parameters to reduce wrinkles caused by uneven pressure. For example, you can reduce the cutting speed, increase the processing intensity, and correctly control the processing gap.

3.Mold improvement

Sometimes it is necessary to improve the mold design or replace the mold with a better quality one to reduce the possibility of wrinkling. You can consider changing the angle and arc radius to optimize the process to avoid wrinkles.

4. Follow-up processing

If wrinkles still occur, subsequent treatments such as sanding or polishing can be used to remove the wrinkles and make the product surface smoother and more uniform.

In short, the wrinkle problem of stainless steel drawn parts is a common processing problem, which can be effectively solved through reasonable material selection, process optimization, mold improvement and subsequent processing.
