Heat shrinking process:
Port heating: Heating the port of the stainless steel pipe above the specified temperature to keep it in a hot state and improve its plasticity.
Rough forging: Rough forging the heated port to achieve the desired shape and size.
Rolling compression port: Use equipment to roll and compress the port to reduce it to the required diameter.
Natural cooling: After shrinking is completed, let the pipe mouth naturally cool to room temperature.
Turning the port: Turning the reduced port to achieve the required accuracy and surface quality.
Cold shrinking process:
Mold preparation: Select the appropriate mold and make sure it matches the size of the stainless steel pipe.
Lubricate the pipe mouth: Apply an appropriate amount of lubricant to the pipe mouth to reduce friction and damage.
Extrusion and compression: Use hydraulic equipment to push the mold and directly squeeze the pipe mouth to reduce it to the required diameter.
Turning the port: Carry out turning processing on the reduced port to ensure its accuracy and surface quality.
In addition to the above-mentioned heat shrinking and cold shrinking processes, there is also a spinning processing method that can also be used for shrinking stainless steel pipes.
It should be noted that the specific steps and parameters of the necking process may vary depending on different equipment and materials. Therefore, in actual operation, it needs to be adjusted and optimized according to specific conditions to ensure the quality and efficiency of shrinkage. At the same time, operators need to have appropriate skills and experience to ensure the safety and reliability of the shrinking process.
