AI Technical Summary
When punching the annular tube, if it is not fixed, it is likely to cause the punching position to shift; when the diameter of the annular tube is large, single-side punching can easily lead to excessive local stress on the pipeline and cause deformation.
The annular tube is fixed by matching the bottom clamp, the top clamp, and the top telescopic cylinder; two symmetrical stamping cylinders are arranged on both sides of the annular tube main body, so that the punching holes are punched at the same time on both sides, avoiding excessive stress on one side.
It effectively avoids positional offset and local deformation of the annular tube during the punching process, ensuring the stability and accuracy of the punching process.
