AI Technical Summary
In existing stainless steel pipe coating processing equipment, the conical head fixing method can easily cause the pipe to slide or fall off, and the interference fit may cause the pipe end to deform, making it difficult to fix and disassemble stably.
The structure adopts an internal support block for internal support. The cylinder drives the telescopic head to open the internal support block. The anti-slip rubber strip is tightly attached to the inner wall of the stainless steel tube to avoid interference fit, ensuring stability and easy disassembly.
This method achieves stable fixation of stainless steel pipes, preventing slippage or falling, and preventing pipe end deformation. It improves the stability and efficiency of the processing, and enhances product quality and pass rate.
