Design Conditions: The new steel pipe inner wall grinding machine is designed with a consideration for steel pipe inner diameters ranging from 300mm to 1000mm, grinding lengths of 4m to 14m, single steel pipe weights not exceeding 11 tons, and a grinding wheel speed of 4500r/min.
Composition: The new equipment consists of a swinging support, a rotating rod, a grinding head, a lifting device, etc. The swinging support provides grinding pressure, the rotating rod is supported by bearings, and the top is placed with a grinding head. The lifting device is used for position changes to adapt to the grinding of steel pipes with different inner diameters.
Working Principle: The steel pipe inner wall grinding machine uses paired rotating rollers to rotate the steel pipe, while the grinding rod drives the high-speed rotating grinding head to extend into the interior of the steel pipe to grind the inner surface. This can quickly remove oxides, rust, scars, creases, and other defects on the inner surface of the steel pipe to obtain a smooth and clean inner wall surface.
Function: It is mainly used in the finishing process of steel pipes to eliminate cracks, scratches, indentation defects on the inner and outer surfaces of steel pipes, and improve the yield rate. The equipment includes a mechanical part and is equipped with corresponding electrical control, hydraulic, lubrication systems, and dust removal systems.
Application Fields: The steel pipe inner wall grinding machine is widely used in enterprises that require high external quality requirements for steel pipes or high value-added steel pipe products to improve the quality and economic benefits of steel pipes.
Technical Features: The new steel pipe inner wall grinding machine can solve the problem of inability to grind the inner diameter of small-diameter steel pipes and remove internal defects that cannot be ground manually, improving the quality and yield of steel pipes. During maintenance and replacement, only the grinding rod and grinding head need to be replaced. The damaged grinding rod can be repaired offline without affecting production efficiency.
Operational Convenience: The new steel pipe inner wall grinding machine has a simple structure, easy production and manufacturing, low cost, convenient operation, large grinding capacity, and uniform grinding.
The introduction of the steel pipe inner wall grinding machine has significantly improved the quality and efficiency of steel pipe processing and is one of the indispensable equipment in the steel pipe manufacturing industry.
