Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a grinding device for processing a seamless steel pipe end. Background Art

[0002] Seamless steel pipe is made of a whole round steel through holes. There is no weld on the surface of the steel pipe, which is called seamless steel pipe. Seamless steel pipe is mainly used as petroleum geological drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-precision structural steel pipe. In order to reduce burrs and improve the convenience of installation, it is necessary to grind the port. After searching, the Chinese patent with publication number CN213998838U discloses a port grinding device for steel pipe processing with dustproof function. The dustproof pipe is set to prevent the debris from grinding from splashing, and an exhaust structure is set at the bottom to remove the debris generated by grinding from the bottom to the bottom. The dust pipe is sucked away from the bottom. Due to the shape and structure of the dust pipe, if there is no exhaust effect of the exhaust structure at the bottom, the debris generated by grinding will splash to both sides of the dust pipe. If the exhaust structure is restarted, it is necessary to overcome the friction between the debris and the inner wall of the dust pipe to suck it back to the middle. Therefore, no matter whether the exhaust structure is started or not in the initial stage of grinding, the energy consumption of debris collection is high. For this reason, a grinding device for seamless steel pipe port processing is designed, which can utilize the debris' own gravity to collect most of the debris during grinding, and quickly start the chip suction structure after the grinding is completed to further collect the debris remaining in the seamless steel pipe and the rest of the debris, thereby reducing the energy consumption of debris collection.
