Numerical control two-roll rolling machine provided with two flexible rolls

Abstract

The invention discloses a numerical control two-roll rolling machine provided with two flexible rolls and belongs to the technical field of machine manufacturing of rolling machines. Aiming at the problem that cylinders have scratches on surfaces when being rolled by the conventional two-roll rolling machine, the numerical control two-roll rolling machine adopts two polyurethane rubber rolls, the diameter of the upper rubber roll is smaller than that of the lower rubber roll, the hardness of a polyurethane rubber layer of the upper rubber roll is higher than that of a polyurethane rubber layer of the lower rubber roll, when a cylinder is rolled, the outer surface quality of a cylindrical part can be better, movement of a lower rubber roll lifting hydraulic cylinder is controlled through hydraulic servo under the condition that the upper rubber roll is not replaced, the distance between the upper rubber roll and the lower rubber roll is changed, cylinders with different diameters in a certain range and multi-curvature cylinders can be rolled, a structure-optimized unloading device is adopted and assisted by automation control, formed ends are prevented from being rolled together with tail ends when sheets are rolled by automatically lifting a cross beam, automatic unloading is realized, the rolling precision is further improved, and the automation degree is further increased.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing of plate rolling machines, in particular to a numerically controlled two-roll plate rolling machine with double flexible rolls. Background technique [0002] With the rapid development of national defense and civilian industries, the demand for cylindrical parts is increasing. Plate rolling machines are widely used for their high rolling precision and fast efficiency. However, for the high quality requirements of the inner and outer surfaces, especially the thin-walled cylindrical parts with high inner surface quality requirements, there is no plate rolling machine on the market that can do it. The existing two-roller plate bending machine consists of a rigid roll and It is composed of a flexible roller, which can ensure the quality of the outer surface when rolling the plate, but the inner surface has scratches in contact with the rigid roller, which is slightly worse than the ou...
