Mine-used U-form steel support rolling forming repair machine

A mine-used U-form steel support rolling forming repair machine is composed of a host computer and an electric-hydraulic console, which mainly comprises a main rolling wheel, an auxiliary roll wheel, a left and a right rolling wheel, a front and a back column, a side roller, a feed cylinder, a swing cylinder, a swing beam, an index disc, a positioning lead screw, a pump station, a low-speed large-torque hydraulic motor, and a two-stage gear speed reducer. The mine-used U-form steel support rolling forming repair machine is characterized in that a transmission shaft II and a transmission shaft I are mounted with roll forming moulds 15 in couple, the transmission shaft II is driven by a first-stage gear pair 17, the transmission shaft I is driven by a second-stage gear pair 16, the two transmission shafts are inversely rotated, the low-speed large-torque hydraulic motor 18 provides output power, the front and the back columns are fixed by a straight beam 12. The mine-used U-form steel support rolling forming repair machine can blank material in fixed length of U-form steel beam and roller bending part, can continuously roll and bend, can automatic form in one time, and has practicality in old U-form steel arc beam support repair.
