Description

A shearing machine with flattening function

technical field

The utility model relates to cutting equipment, in particular to a plate shearing machine for cutting plate bodies. the

Background technique

The plate shearing machine is an automatic processing equipment that precisely controls the processing size of the plate, performs automatic cycle shearing processing on large metal plates, and is transported to the next process by the feeding car. During the shearing process of the plate, it uses programmable The controller controls the automatic shearing machine, and the cutting length of the plate is controlled by the stopper set behind the cutter, that is, the distance between the cutter and the stopper is the length of the cut plate. the

Before the plate is sent to the shearing machine, a leveler is generally used to flatten the plate to ensure that the plate is flat, and to ensure that the length of the plate cut on the shearing machine is the actual length obtained. However, before the plate body is sent to the shearing machine after leveling, it is prone to collision during storage or transportation, and the bending will cause the surface of the plate body to be uneven (especially for plates with low hardness such as aluminum plates). During the shearing process, as shown in Figure 1, the cutting length of the plate body 3 is the distance between the tool 1 and the stopper 2. Since the surface of the plate body 3 is not smooth, the actual length of the plate body 3 obtained is greater than the actual required length of the plate body L, so that the plate cannot meet some requirements for high-precision assembly of the plate. Therefore it is necessary to improve it. the
