Technical field
The utility model belongs to the centreless coiling machine in the steel rolling equipment, and particularly a kind of centreless coiling machine is with hydraulically powered bending roll device.
Background technology
At present, with the good band of mill milling, be to adopt traditional centreless coiling machine to batch moulding; The process of its band brake forming: at first, send into before the bending roll mechanism according to the power of setting of depressing by upper and lower feeding roller, operating personnel are according to the thickness of slab size, adjust what a bending roll and stationary roll position according to technological requirement by the manual worm decelerator, roll gap requirement when making it reach band and enter, usually be satisfied with on the frame this, the bending roll that the manual worm decelerator is adjusted is called the thickness flexure roller.Simultaneously according to material curve internal diameter size, adjust another bending roll position by the electric driving mechanism of forming by motor, shaft coupling, worm reducer, usually this bending roll of being satisfied with electronic drive mechanism on the frame, be called the external diameter bending roll.When band enters the bending roll mechanism that is made up of above-mentioned two bending rolls and stationary roll, band produces the elasto bending distortion under the effect of three rollers, along with the band continuous bend, band forms radius on carrying roller after leaving bending roll system, and radius is exactly the roll coil of strip internal diameter of being produced; In curly course, the bending roll position of electronic control needs constantly to change to adapt to the variation of roll coil of strip external diameter, so the thickness flexure roller of existing centreless coiling machine and the driving mechanism of external diameter bending roll, be subject to the people ability and muscle power, can not realize automation control, problems such as event exists response speed slow, and efficient is low; It can not satisfy batch that thickness range is big, draw off rate is high, the coiled material external diameter is big, response speed is fast, automaticity is high modernized rolling line is to the high efficiency requirement of centreless coiling machine.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, both be adapted to automation control, satisfy again and batch that thickness range is big, draw off rate is high, the coiled material external diameter is big, response speed is fast, and having the production efficiency height, handling safety uses a kind of very easily centreless coiling machine with hydraulically powered bending roll device.
The purpose of wood utility model is to adopt following technical scheme to realize: described centreless coiling machine is with hydraulically powered bending roll device, comprise stationary roll, thickness flexure roller, external diameter bending roll on the frame, it is characterized in that: the mechanism that on frame, is equiped with activity loading, unloading stationary roll; Corresponding with the two axial ends position of thickness flexure roller, symmetry installing drives thickness flexure roller upper and lower motion, synchronous hydraulic drive mechanism on the base of frame lower; Corresponding with the two axial ends position of external diameter bending roll, symmetry installing drives external diameter bending roll upper and lower motion, synchronous hydraulic drive mechanism on the base of frame lower.
The mechanism of described activity loading, unloading stationary roll, boss and cushion block by driver, stationary roller shaft bearing, stationary roller shaft bearing are formed, installing or on the stationary roller shaft bearing by hydraulic cylinder or by jack or by the driver of lifter, stationary roller shaft bearing bottom surface is provided with boss, corresponding with position, shape, the size of boss, be provided with the chute that can make the free ascending, descending of boss in support, corresponding with the chute height, between stationary roller shaft bearing top and support, put the cushion block of being with the inclined-plane.During work, cushion block is unloaded; When needs unload stationary roll, as long as rely on driver that cushion block is encased inside, make on the stationary roll and move, just can unload stationary roll.Loading, unloading when giving the maintenance stationary roll bring operation very easily.
The upper and lower motion of described each thickness flexure roller, synchronous hydraulic drive mechanism, form by thickness flexure roller base, bloster hinge, hydraulic cylinder, hinge head, slide block and bearing block, on frame by the bolting base, hinge frame on the base is connected by bearing pin with the hinge frame of hydraulic cylinder bottom, the expansion link of hydraulic cylinder is connected with the hinge head thread, the hinge head is installed in the T type groove of slider bottom, slide block can move up and down in the slideway of frame, the upper end of slide block fixed bearing block, bearing block support thickness bending roll.
The upper and lower motion of described each external diameter bending roll, synchronous hydraulic drive mechanism, form by base, bloster hinge, hydraulic cylinder, hinge head, slide block and bearing block, on frame by bolting external diameter bending roll base, hinge frame on the base is connected by bearing pin with the hinge frame of hydraulic cylinder bottom, the expansion link of hydraulic cylinder is connected with the hinge head thread, the hinge head is installed in the T type groove of slider bottom, slide block can move up and down in the slideway of frame, the upper end of slide block fixed bearing block, bearing block supports the external diameter bending roll.
Principle of the present utility model and operation are described below: band is before sending into the bending roll system by feeding roller according to the power of setting of depressing, feeding roller, thickness flexure roller, external diameter bending roll, carrying roller are rotated to same direction with same line speed through gearbox by motor, simultaneously adjust the relative position of bending roll and stationary roll according to thickness of slab size, material curve internal diameter size, technological requirement by control system, the roll gap when making it reach band and enter requires, adjusts the relative position of external diameter bending roll and thickness flexure roller and stationary roll and adjusts the bending roll system.Band is sent in the roll gap of external diameter bending roll and stationary roll through guide plate by feeding roller, external diameter bending roll and stationary roll together clamped the band rotation and drove band and continue to move to the bending roll direction this moment, when strip ends touches bending roll, band produces the elasto bending distortion, the band rotation of together nipping of bending roll stationary roll.Along with the band continuous bend, band forms radius on carrying roller after leaving bending roll system, and radius is exactly the roll coil of strip internal diameter of being produced, in continuous curly course, the bending roll position need constantly move down, when the fourth hand finishes, bending roll stops to move down, and finishes a working cycles.Its handling safety is used very convenient.Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model is not only reasonable in design, compact conformation, both be adapted to automation control, and satisfied again and batch that thickness range is big, draw off rate is high, the coiled material external diameter is big, response speed is fast, and have the production efficiency height, handling safety is used advantages such as very convenient.
