5results about How to "Effective straightening" patented technology

The application discloses a kind of based on rolling time domain control concept's scraper conveyor straightening method, it is solved that the existing scraper conveyor straightening method exists and cannot realize straightening situation because of not considering the dynamic change of coal seam floor form, cannot realize single cutter straightening and other problems because of information hysteresis;The scraper conveyor straightening method includes execution space, deduce space, prediction space;Execution space receives the final determination of scraper conveyor optimal push and roll strategy of prediction space, controls the push and roll operation of subsequent scraper conveyor by electro-hydraulic control system according to optimal push and roll strategy to reach the purpose of scraper conveyor straightening;While, working face real-time information is fed back to deduce space;Deduce space deduces working face real-time information, and deduce information is sent to prediction space;Prediction space receives the deduce information of deduce space and carries out analog prediction, finally determines the optimal push and roll strategy of scraper conveyor.

The utility model provides a high-speed wire rod discharging clamping and straightening device. The high-speed wire rod discharging clamping and straightening device comprises two vertical clamping and conveying devices and a horizontal straightening device located between the two vertical clamping and conveying devices. The vertical direction clamping and conveying device comprises a clamping and conveying support which is fixedly arranged; the first vertical roller frame is fixedly arranged on the pinch support, and a free connecting end is reserved at one end of the first vertical roller frame; one end of the second vertical roller frame is hinged to the clamping and conveying support, the other end of the second vertical roller frame is a free connecting end, and the second vertical roller frame and the first vertical roller frame are arranged at intervals in the vertical direction; the pinch rolls are respectively mounted between the two vertical roll racks, and a wire pinch straightening space is formed between the two pinch rolls above the two vertical roll racks; and the first telescopic piece is connected between the free ends of the two vertical roller frames, and clamping and straightening of the clamping and conveying roller are achieved through stretching and retracting of the first telescopic piece. According to the straightening device, the wire elbows can be effectively straightened in a labor-saving mode through overturning and clamping of the clamping rollers on the second roller frame hinged to the clamping support.

The application discloses a spring steel wire section shaping device, which comprises a workbench, a guiding assembly, a traction assembly and a shaping assembly which are sequentially arranged on the workbench, the traction assembly comprises two symmetrically arranged mounting racks, a mounting plate arranged on the mounting rack, an upper traction roller and a lower traction roller arranged on the mounting plate, the shaping assembly comprises two symmetrically arranged vertical racks, a vertical plate arranged on the vertical rack, an upper shaping roller and a lower shaping roller arranged on the vertical plate, and a driving device for synchronously driving the upper traction roller, the lower traction roller, the upper shaping roller and the lower shaping roller to synchronously rotate is arranged between the traction assembly and the shaping assembly. The device has the following beneficial effects: the spring steel wire is subjected to uniform pressure in the whole processing process through accurate control of traction force and shaping pressure, thereby ensuring the consistency of the diameter and the accuracy of the section shape of the spring steel wire, and effectively solving the problem of local fracture caused by large diameter difference.

The utility model relates to the technical field of channel steel recovery, in particular to a tool clamp for channel steel recovery, which comprises a straightener body, a first fixing plate fixedly connected to the top of the straightener body, a second fixing plate fixedly connected to the top of the straightener body, and a channel steel body placed inside the straightener body. Straightening plates used for straightening a web plate of the channel steel body are installed in the straightening machine body at equal intervals, straightening rollers used for straightening a flange of the channel steel body are installed in the straightening machine body at equal intervals, and first adjusting assemblies used for adjusting the straightening plates are installed in the straightening machine body and on the outer side of the first fixing plate; second adjusting assemblies used for adjusting the straightening rollers are installed in the straightening machine body and on the outer sides of the second fixing plates. The tool clamp for channel steel recovery has the advantages of being efficient in straightening, accurate in adjustment, high in universality and capable of protecting channel steel.

This utility model relates to a device for straightening the bends of steel profiles, belonging to the technical field of hot-rolled steel profiles in the metallurgical industry. The technical solution includes an adjustable guide groove mechanism and a straightening mechanism arranged front and rear. Two guide plates form a V-shaped guide groove with an opening facing the exit of the finishing mill. The steel profiles exiting the finishing mill pass through the V-shaped guide groove and enter the subsequent straightening mechanism. The two straightening rollers in each group of the straightening mechanism correspond and match with two straightening rollers on the other side of the roller table. The steel profiles exiting the adjustable guide groove mechanism enter the straightening mechanism, and the bends of the steel profiles are straightened after passing through the straightening rollers on both sides of the roller table. The beneficial effects of this utility model are: it can effectively straighten the bends of the finished steel profiles after exiting the finishing mill, avoiding equipment downtime caused by steel profile bends during production and improving production line efficiency.
