1. , machine is repaired in a kind of mining U shape steel bracket roll forming, form by main frame and electrichydraulic control platform two large divisions, mainly comprise main roller, secondary running roller, a left side, right roller, before, rear column, the side roller, the feeding cylinder, oscillating cylinder, walking beam, dial, the location leading screw, pumping plant, low-speed big oil motor and 2 grades of mechanical reduction gears etc., it is characterized in that:

  • front column (7), rear column (13) is fixed on frame (1) table top, power transmission shaft II and power transmission shaft I go up mounted in pairs roll die (15), power transmission shaft II is driven by one-level gear pair (17), power transmission shaft I is driven by secondary gear pair (16), mutual backwards rotation, fix with a word beam (12) between the column of front and back, low speed high torque hydraulic motor (18) provides outputting power, axle head is the reduction pinion teeth of one-level gear pair (17), the deceleration gear wheel is fixed on power transmission shaft II stage casing, hypomere is the reduction pinion teeth of secondary gear pair (16), epimere is the die of roll extrusion grinding tool (15);

    The deceleration gear wheel of secondary gear pair (16) be contained in power transmission shaft I hypomere, epimere fixing be the punch of roll extrusion grinding tool (15), low speed high torque hydraulic motor (18) slows down through secondary gear and drives main roller and rotate;

    Between main frame and pumping plant by conduit under fluid pressure interface (8) with hydraulic pressure high-pressure rubber pipe (24) etc. be connected, electric liquid centralized Control, both sides roller (3) is installed in walking beam (2) and goes up, by oscillating oil cylinder (5) walking beam (2) is swung, and pendulum angle shows by dial (6);

    Side roller (3) advance and retreat move back and forth and use feed cylinder (27), feeding cylinder (31) control respectively.
