Product Scheme

The double - head steel pipe internal cylindrical grinding machine is a special equipment used in the steel pipe industry to correct defects on the inner wall of steel pipes and remove oxide scales. Its working principle is as follows: The double - head internal cylindrical grinding machine is equipped with two grinding wheel heads. The grinding wheels rotate to remove the surface oxide layer and other defects on the inner circle of the workpiece. The steel pipe rotates on two supporting roller trolleys, and the two grinding wheel heads feed axially from both ends of the steel pipe simultaneously (one - in - one - out mode) to complete the grinding of the entire workpiece. The grinding process adopts the dry grinding method. After the workpiece position is adjusted, the two grinding heads can realize automatic processing and automatic stop under the control of PLC.

The internal grinding machine of our company adopts a double - grinding head structure that meets Party A''s technical requirements, and is mainly composed of the following ten major components:

1. Track Device

2. Grinding Rod Trolley Device

3. Support Rod Trolley

4. Rotating Supporting Roller Trolley

5. Drag Chain Support Accessories

6. Grinding Rod

7. Dust Removal Device

8. Dust Removal Track

9. Electrical Control System

(Feeding by crane or roller conveyor → Inspection → Grinding head B → Discharge frame → Double - position pneumatic flap → Steel pipes are laid flat on the rack from the feeding area, and adjustable baffles block the steel pipes at appropriate positions → The double - position flap takes materials once, and the steel pipe is transported to the first grinding position, then the grinding head starts grinding → After grinding, the double - position flap starts again, and the steel pipe at the first position is moved to the second position for dust blowing treatment → A self - suction dust collector is installed at the other end of the dust blowing, and a dust blowing pipe is also installed on the grinding rod for simultaneous grinding and blowing)
