压下量英文表示

尊敬的用户 希望你采纳 With the technology, more and more high-quality sheet metal, straightening has become an important and indispensable process. Straightening machine parameters are reasonable force to design and the use of straightening machine on the basis of how specific the process of straightening straightening, bending moment and the power transmission and the actual straightening of the program link is an urgent need to resolve technical issues To improve the quality of straightening plates are also of great significance. With the computer set-bending amount of straightening machine (commonly known as reduction) of the exact needs of a preliminary analytical methods and numerical methods. And when large deflection bending to resume missile deflection and residual deflection separate calculation, calculation residue in the deflection, as a hypothetical external force generated by the equivalent of the deflection, and then equivalent to the deflection into the deflection and elastic-plastic deflection The use of numerical integration method, will be quite accurate. Compare the value of experience and on-site verification, the practical conclusions can be drawn. The amount of bending leveler there are some approximate calculation method in improving the accuracy of the request has lost value. Abroad have been using computer-bending amount of the mathematical model used to develop the domestic has also started research in this area [1]. Mathematical model of precision and ease of use of the efficiency of straightening a greater impact on the introduction of computer control of the straightening machine performance to play significance. This is a simple and accurate search for a wide range of practical mathematical model, including analysis and a numerical calculation, the shell will resume with the amount of residues in separate, and then residues with the imaginary external force equivalent to deal with the results after the combined amount of bending Law. Is accurate, is equivalent to deal with similar, results are available. 1 straightening force In parallel to the rolling straightening roller straightening machine, in the role of the roller under pressure all the conditions to achieve a balanced cross-section moment: In the role of the roller up and down on the pressure and are as follows: Where, Mi for the first i-roll straightening Department suffered rolling moment; Pi for the first i-roll straightening the edge. All kinds of the above shows that desires a role in straightening roller on the pressure, make sure that the Department roller rolling value of the bending moment. Value of the moment decision on the size of the bending deformation, that is determined by the curvature of the original and anti-bending rate

在轧制过程中轧件的高宽长尺寸都发生变化。轧制后轧件高度的减少量叫做压下量。即△h=H-h式中△h-压下量，㎜；H - 轧件在轧制前的高度，㎜；h - 轧件在轧制后的高度，㎜；

PSI是压力计量单位，磅/平方英寸PSI英文全称为Pounds per square inch。P是指磅pound，S是指平方square，I是指英寸inch。美国习惯使用psi作单位。1psi=6.895kPa=0.0689476bar =0.006895MPa
