Cast iron pipe outer wall grinding device

Abstract

The invention relates to the technical field of cast iron pipe machining and particularly discloses a cast iron pipe outer wall grinding device. The cast iron pipe outer wall grinding device comprises a supporting frame. The supporting frame is provided with at least one pipe grinding mechanism capable of walking on the supporting frame. The pipe grinding mechanism is used for grinding the outer wall of a cast iron pipe. A rotary carrier roller set is arranged below the supporting frame, and comprises a plurality of pairs of carrier rollers arranged in parallel. The portion between each pair of carrier rollers is used for bearing the cast iron pipe. The carrier rollers are driven by a drive mechanism to rotate to drive the cast iron pipe to rotate. The cast iron pipe outer wall grinding device further comprises a vibrating device and a blowing device. The vibrating device is arranged below the supporting frame and used for making the cast iron pipe vibrate on the carrier rollers. The blowing device is arranged on one side of the supporting frame and used for blowing the inner surface and the outer surface of the cast iron pipe. The pipe wall of the cast iron pipe can be effectively ground and cleaned, efficiency is high, the quality of the surface of the outer wall of the formed cast pipe can be improved, adhesive force of a paint film is improved, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of cast iron pipe processing. Background technique [0002] In the current production process of centrifugal cast iron pipes, it is often necessary to grind the outer wall of the pipe to clean the surface of the outer wall to meet customer and production requirements. The prior art usually uses manual hand-held grinding wheels for grinding, which has high labor intensity, low efficiency, and potential safety hazards. [0003] CN 203062457 U discloses a grinding and processing device for the outer wall of petroleum screen tubes with dust removal function, which includes a frame, and a grinding tube mechanism that can walk on the frame for grinding operations is arranged on the frame. The pipe grinding mechanism is provided with a dust removal device; in the frame, there are multiple groups of load-bearing work rolls composed of two oppositely arranged work rolls for placing the pipes to be polished. The wor...

Problems solved by technology

However, with the metal dust produced by grinding with this device, part of the dust that falls from the air to the ground can be sucked by the fan when it lands close to the fan, but there will still be a large amount of metal dust or debris attached to the surface of the oil screen, which cannot be sucked by the fan. Suction, grinding can not meet the cleaning requirements of the pipe wall, still need to manually clean the second time, the dust residue on the surface of the pipe wall is large, the cleaning effect is poor after grinding, and manual cleaning still has the risk of dust pollution
