Blank seamless steel pipe cutting plane chamfer flow
1. Preliminary preparation
Material selection:
Select high-quality seamless steel pipe as the blank to ensure that the chemical composition, mechanical properties and surface quality of the steel pipe meet the relevant standards.
Equipment preparation:
Prepare necessary processing equipment, such as straightening machine, cutting machine, milling head chamfering machine, grinding machine, etc.
Ensure that all equipment is in good condition and that necessary checks and calibrations are carried out.
Measurement and marking:
Use tools such as vernier calipers to accurately measure the size of seamless steel pipes and determine the position of cutting and chamfering.
Mark the steel pipe for subsequent processing.
2. Cutting process
Straightening treatment:
The seamless steel pipe is straightened to eliminate the bending and distortion of the steel pipe and ensure the flatness of the cutting surface.
Cutting operation:
Use cutting machines (such as laser cutting machines, plasma cutting machines, etc.) to cut seamless steel pipes.
In the cutting process, pay attention to control the cutting speed, feed rate and cutting depth to ensure the quality of the cutting surface.
3. Plane chamfering process
Chamfer equipment selection: According to the size and chamfer requirements of seamless steel pipe, choose the appropriate chamfer equipment (such as milling head chamfer machine, grinder, etc.).
Chamfering operation:
Fix the cut seamless steel pipe on the chamfering device.
According to the predetermined chamfer Angle (it is generally recommended to master between 15-30 degrees, excessive chamfer will cause pressure loss) for chamfer processing.
In the chamfering process, pay attention to control the chamfering speed, feed rate and cutting depth to ensure the smoothness and uniformity of the chamfering surface.
4. Follow-up treatment
Check and repair:
Check the seamless steel pipe after chamfering to ensure that the chamfer Angle, smoothness and uniformity meet the requirements.
If the chamfer effect is not ideal, it should be trimmed in time.
Cleaning and protection:
The seamless steel pipe after chamfering is cleaned to remove metal chips and oil stains generated during processing.
As required, the steel pipe should be treated with rust prevention or coated with protective coating.
