Pinch Roller Pinch Technology Theory And Research

Pinch roller device is one of the key equipment in plate production line, it's mainly used for clamping and delivery blanks in side shear, and stock length in sizing shear. It's common in pinch roller device that the deviation have existed, it has seriously affected steel cutting, the quality of cutting length and the improved of quality. This paper will analysis the pinch roll deviation through the organization theory, and micro-scale deformation during the operation on the various components to identify the reasons for deviation. And a kind of adaptive tapered roller pinch roll unit has developed to achieve a operation smoothly and precisely. The completion of this thesis will play an important guiding significance on the high-precision machining of plate and strip.Detailed analysis of this paper in the pinch roll during operation of the force of each key part of the situation, deviation rate of the sheet is introduced into the final analysis, the pressure from the hydraulic cylinder and the final objective function of the actual state of plate have been establishment. The relationship on each factor has been deduced. The pinch roll unit appear roller diameter difference in running, the micro-scale deformation, the relationship between the neutral and other factors have been analysis theoretically. And to take a combination of theory and practice method, the experimental analysis of the factors and demonstration proved its credibility. It's can be based on specific parameters and factors regulating the pinch roll in the actual production, to enable them to minimize the risk of deviation, to reduce the possibility of deviation occurs, to improve production efficiency.The main innovation of this paper:(1) According to the mechanical structure of the pinch roll, the quantitative relationship between pressure and micro-deformation has been derived, that can provided theoretical support for the design and reconstruction.(2) The middle set of a new pinch roller cone body have been designed and developed which can eliminate the roller and shaft misalignment caused by the deviation.(3) Developed a new adaptive pinch roll of flexible hinge body to adapt to incoming change, to avoid the pinch roll steel belt deviation phenomenon.
