AISI4130 AISI4140 seamless tube
AISI4130 AISI4140 seamless tube Polishing device
The utility model relates to blind hole polishing technology, and open a seamless steel pipe blind hole polishing device, including the workbench, described in the table are fixed on both sides at the top of the connection has a fastening device, described at the top of the table on the right side of a fixed connection has a pillar, the pillar of the lateral sliding connection with sliding sleeve, referred to the top of the workbench hydraulic push rod hinged on the right side, the hydraulic push rod away from One end of the table is hinged with the right side of the sliding sleeve, and the left side of the sliding sleeve is fixedly connected with a lifting plate, and the top of the lifting plate is fixedly installed with a rotating motor, and the output shaft of the rotating motor is fixedly connected with a rotating shaft. The utility model has the advantages of adjustable blind holes adapted to different pore sizes, stable polishing and quality improvement, and solves the problem that the diameter of the polishing mold is fixed, the blind holes of different pore sizes cannot be matched, and the hand-held seamless steel pipe is needed to adapt to the polishing mold, which leads to the polishing instability and low polishing quality.
