Fixed length plate shearing machine applicable to plates of different thicknesses

Abstract

The invention discloses a fixed length plate shearing machine applicable to plates of different thicknesses. The fixed length plate shearing machine comprises a machine base (1) and a machine cover (2). Supporting plates (8) are arranged on the machine cover (2), upper shaft rollers (7) are mounted between the two supporting plates (8), pressing plates (9) are arranged on the outer sides of the two supporting plates (8), and the pressing plates (9) are connected with piston rods of vertical cylinders (10). Two lifting devices are respectively and symmetrically arranged on the two sides of the machine base (1) and the two sides of the machine cover (2). The two lifting devices on each side are arranged at the two ends of the machine base (1) respectively. The fixed length plate shearing machine has the advantages that due to the arrangement of the pressing plates, the smoothness in the plate shearing process is guaranteed, the dimensional precision of sheared metal plates is high, and material waste is avoided; due to the arrangement of the lifting devices, the metal plates of different thicknesses and specifications can be sheared by the plate shearing machine, the applied range of the machine is widened, equipment cost is lowered, and the utilization rate of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of plate shearing devices, in particular to a fixed-length plate shearing machine suitable for different plate thicknesses. Background technique [0002] Shearing machine is a kind of automatic processing equipment that precisely controls the processing size of the plate, automatically cyclically shears the large metal plate, and transports it to the next process by the feeding car. In the process of shearing the plate, programmable The controller controls the automatic shearing machine, and the cutting length of the plate is controlled by the stop set behind the cutter, that is, the distance between the cutter and the stop is the length of the cut plate. [0003] Before the board is sent to the shearing machine, a leveling machine is generally used to flatten the board to ensure that the board body is flat, and that the length of the board body cut on the board shearing machine is the actual length.

Problems solved by technology

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.

Therefore, when the plate is cut, when the end of the plate touches the stopper, the actual length of the plate is longer than the set cutting length due to the bending of the plate, so that the product size does not meet the requirements and wastes raw materials

Moreover, the conveying device currently used to transport plates can only be used for plates of the same thickness. However, due to the variety of thickness specifications of plate products, in order to facilitate the processing of plates of various thicknesses, it is often necessary to set up corresponding shears according to the thickness specifications of the plates. , which results in an increase in production costs and a waste of resources
