Roller way for shear line and shear production line

Abstract

The invention discloses a roller way for a shear line and a shear production line. The roller way for the shear line comprises a plurality of roller assemblies, the plurality of roller assemblies arearranged at intervals in the conveying direction of the roller way for the shear line, the axes of the roller assemblies are all located in the same horizontal plane, the axis of at least one roller assembly in the plurality of roller assemblies is obliquely arranged relative to the conveying direction, in the process that a steel plate (1) advances on the plurality of roller assemblies in the conveying direction, at least one roller assembly can enable the steel plate (1) to move towards a fixed edge (10) of the roller way for the shear line and enable the side edge of the steel plate (1) tobe completely attached to the fixed edge (10). According to the roller way for the shear line and the shear production line, the axes of part of the roller assemblies in the roller way for the shear line are obliquely arranged relative to the conveying direction, in the process that the steel plate advances on the plurality of roller assemblies, automatic side leaning operation can be achieved, anindependent side leaning device does not need to be arranged any more, and cost is saved.

Description

technical field [0001] The invention relates to the field of metallurgical machinery and equipment, in particular to a roller table for a shearing line, or a shearing production line containing the roller table for a shearing line. Background technique [0002] The medium and thick plate shearing line is generally equipped with cutting head shears, double-sided shears and fixed-length shears. These three shears require the steel plate to be close to the fixed side during transportation to ensure the rectangularity and accuracy of the steel plate after shearing. Usually, an edge device is usually installed on the roller table on the entrance side of the shearing machine to ensure that the steel plate can be transported close to the fixed side (ie, the fixed side). However, if the edge device is installed separately, it will affect the rolling rhythm and ultimately affect the output; it will also increase the one-time investment cost, and the cost will also increase during the...

Problems solved by technology

However, if the edge device is installed separately, it will affect the rolling rhythm and ultimately affect the output; it will also increase the one-time investment cost, and the cost during operation will also increase

The wider steel plate rolling line is generally wider in width. Usually, the roller table is driven at one end, and the widest roller table is 5000mm wide. One end of the roller table is frequently subjected to torque transmission to the entire roller body, and the entire roller table is transported under stress. Uneven, long-term forward and reverse operation, motor shaft breakage accidents will occur

The width setting of the roller table must be wider than the widest steel plate, but in actual use, products with a medium width are often produced, and the frequency of use of the non-fixed side roller table is low. Long-term operation will cause serious wear on the fixed side roller surface, and the entire roller Uneven surface wear
