3results about How to "Improve rolling precision" patented technology

The utility model belongs to the field of rolling technology, specifically is a kind of export sliding guide adjustment structure, including guide box;The guide box top is rigidly connected with stepper motor;Stepper motor output end is rigidly connected with rotating rod;Rotating rod both ends are rotatably connected with connecting rod;Connecting rod end is rotatably connected with support;The support one side is rigidly connected with wheel carrier;Wheel carrier both ends are slidably connected with slide rail;Wheel carrier bottom is rotatably connected with a group of guide wheels;The guide wheel bottom is rotatably connected with sliding block;A group of sliding grooves are arranged in the guide box top;The spacing between multiple groups of guide wheels can be adjusted by the rotation of rotating rod and related components driven by stepper motor, to adapt to the rolling conveying needs of different diameters, and multiple groups of guide wheels form continuous guide channel, apply uniform constraint to rolling, reduce deviation or shaking of rolling in conveying process, and its along straight line enters next rolling process, improves rolling precision and product quality.

This invention discloses a rolling method for 0.1mm thick ultra-flat and ultra-hard precision stainless steel sheets, including: preset rolling parameters, production preparation, rolling, and post-rolling cooling. The preset rolling speeds are: 100-120 m / min for the first pass, 90-100 m / min for the final pass, and 110-120 m / min for intermediate passes; the preset rolling pressures are: 740-800 KN for the first pass, 950-1000 KN for the second pass, and [missing information - likely related to the final pass]. The rolling pressure is 700-760 kN, with intermediate passes at 700-800 kN; the rolling oil temperature throughout the rolling process is 35-40℃; the preset plate profile curve is set as follows: slope value -20-40, center waviness value 80, and edge waviness value 20; the rolls are M42 rolls with a diameter of 38-40 mm; the roughness of the rolls used in the finishing pass and the pass preceding the finishing pass is 0.4-0.5 μm, and the roughness of the rolls used in the first pass and the remaining intermediate passes is 0.5-0.6 μm. This invention can produce 0.1 mm ultra-flat and ultra-hard precision stainless steel sheets with qualified and uniform surface roughness and flatness, small thickness tolerance fluctuations, stable surface quality, and effectively improved rolling accuracy, product qualification rate, and production efficiency.

The utility model discloses a kind of anti-deviation steel strip rolling device, it is related to steel strip rolling technical field.The utility model includes bottom box, the bottom box top side is fixedly connected with rolling frame, the rolling frame inside is fixedly connected with bottom roll, the bottom roll rear side is fixedly connected with drive box, the rolling frame inside is threadedly connected with adjusting lever, the adjusting lever bottom is movably connected with top roll by bearing.The utility model is designed by anti-deviation roller of conical body shape, when steel strip deviates, its inclined plane is contacted with steel strip edge, because the linear velocity gradient of roll surface changes along axial direction and forms asymmetric lateral friction force, restoring force pointing to rolling center is generated, drive steel strip automatic return normality.Anti-deviation roller is driven by second driving motor, keeps same direction rotation, avoids shear stress caused by reverse rotation, reduces steel strip edge scratch, indentation and edge curl risk, significantly improves rolling precision and product quality.
