Straightening machine is a metal bar, pipe, wire, and other equipment for straightening. Straightening roller straightening machine through the bars of pressure for them to change, such as straightness. There are two rows of straightening roller, the number of ranges. There are also two roller straightening machine, relying on two rollers (Concave Intermediate, hyperbolic roll) the perspective of the different changes in the diameter of the material straightening. Type of straightening of the main pressure, balance roller straightening machine, shoes roller straightening machine, anti-rotation bending leveler and so on.7095

This process of straightening machine is: the location of the roller straightening products and the direction of the movement as a point of view, two or three of the initiative is a pressure roller, driven by the motor for rotating in the same direction, on the other side of a number of A small roller was driven roller pressure, they are relying on a rotation of the rod or pipe so that the friction of the rotation. In order to achieve roller on the products required by the compression of these small roller at the same time or separately adjustments backward or forward position, in general the number of roller more after straightening products, the higher accuracy. Products have been biting into the roller, continue to make a straight line or rotary movement, making products to bear all aspects of compression, bending, squash, such as deformation, to reach the final straightening.
Foreword the technology belongs to the metal working discipline abranch, already widely applied to the everyday use metal working industry, instrument measuring appliance manufacturing industry, automobile, ships and airplane manufacturing industry, petroleum industry, metallurgical industry, building material industry, machinery equipment manufacturing industry, as well as precise processing manufacturing industry. The technology can further solve some hard problems in the breadth and the depth aspect huge development urgent need theory, impels to develop the new technology and to develop the new equipment. 16 is especially big after the party, requests with the information impetus industrialization, the technology also needs to follow the time. First must in the straightening machine design, the manufacture, the process analysis, the parameter hypothesis and the quality forecast and so on the aspect does well the software development; It secondary carries on the digitized equipment the development, causes the technology to step on to modernized the path, unceasingly rich metal study content.
The technology has equally made the considerable progress with other metal working technologies in 20thcentury, the corresponding theory has also made the very big progress. But the theory lag quite is obvious to the practice phenomenon. For example the negative torque destructive effect only then can solve in 20th century next half, but its destructive effect mechanism was only then expounded until the end of 1980s. Moreover, the theory overall looked that, still was at the rough stage, first was its basic parameter determination also must depend upon many experiences algorithms and the empirical data, roller distance, roller diameter, Next is many technical phenomena like spiral curved waste product, the noise, the slanting roller characteristic, the slanting roller roller shape characteristic, the distortion match characteristic and so on all lacks the theory elaboration; Is once more the theory concise quality is insufficient, set of formulas not only cannot include each kind of cross section molding, even cannot include the similar cross section but the size and the material quality different work piece, like the curved distance and so on all lacks the general expression with the curvature.
In addition this design in many tiny place also makes every effort to draw close to the reality, carries on when each kind of most massive computations must feasible use which to achieve the value replaces actual does not answer the theory limit value. The application technology theory lies in the practice to be feasible or not, the practical application is this design basis. Key: huge development theory concise massive computations phenomena like.
