Method for adjusting horn mouth of circle shears by applying orthogonal method

Abstract

The invention provides a method for adjusting a horn mouth of circle shears by applying an orthogonal method. The method comprises the following steps of: building a central line of a unit; leading two vertical lines from the central line; making an oscillating bar; fixing the oscillating bar at one side of a shear blade shaft of a left circle shear; fixing an inside micrometer at an upper end of a vertical rod of the oscillating bar; rotating the shear blade shaft of the circle shears to measure; reading and recording reading value of the inside micrometer; measuring the other side of the shear blade shaft of the circle shears and the shear blade shaft of another circle shear according to the steps; and comparing read and recorded reading values, if the reading value error of the inside micrometer is larger than a range, repeatedly measuring and adjusting until a standard error requirement is reached. By the method, a horn mouth state of two circle shears can be accurately and rapidly measured and adjusted, the problems of accurate measurement and accurate adjustment on the horn mouth state of a shear blade of a double-head circle shear are effectively solved, the shear blade is prevented from being damaged, the shearing edge quality is improved, and waste quantity and quality problem of products are reduced.

Description

technical field [0001] The invention belongs to the field of rolling equipment testing, and in particular relates to an orthogonal method for measuring and adjusting the dimensional accuracy of the bell mouth of a cold-rolled disc shear blade. Background technique [0002] Strip disc shears of cold rolling and tandem rolling mills play an extremely important role in production. Usually, the outlets of the cutting blades on both sides of the disc shears are designed to be slightly larger than the inlets to form a so-called bell mouth. When cutting, the two cutting blades form a shape that is larger than the inlets. The purpose is to ensure the cutting quality and accuracy. , so that the strip passes through the shearing edge smoothly. [0003] There are generally two types of bell mouth for disc shears. One is to process the shaft holes on both sides of the shear blades into a bell mouth state during manufacturing and processing. There is no need to consider the bell mouth p...

Problems solved by technology

In fact, the state of the bell mouth is far from the real need. If the state of the bell mouth of the disc shears is not adjusted well, it is easy to damage the cutting edge, resulting in frequent replacement of the cutting edge. Burrs, edge cracks appear after rolling through the rolling mill, resulting in quality objections or scrap
