Problems solved by technology

[0002] The prior art uses bench shears as equipment for cutting thin steel plates, and adopts a cutting table without gaskets. The existing defect is that it is mainly used in occasions where ordinary thin steel plates have no requirements for the accuracy of external dimensions. The cutting accuracy is low, and the size of the cut steel plates cannot be accurately controlled. And the shape; the operator has high labor intensity, low work efficiency, the handle is too long, and cannot be used when the operating space is limited

Abstract

The invention discloses a steam turbine girdle gasket dedicated bench snips which comprise a base, a workbench support, a workbench, a cutting board, a connection rod and a handle. The workbench is connected with the workbench support, the workbench is provided with a limit plate and a graduated disc, the workbench is connected with the limit plate through studs, flat washers and butterfly nuts, the workbench adjusts the relative position of the workbench and the limit plate through the studs, the flat washers and the butterfly nuts, the base is provided with a limit block, and the workbench support is connected with the base through screws. One ends of the cutting board and the connection rod are connected with the base, and the other ends of the cutting board and the connection rod are fixedly connected with the handle. The steam turbine girdle gasket dedicated bench snips are simple in structure, and convenient to operate, reduce the working strength of operation staff, save working space, improve process efficiency, and is suitable for the accurate and mass production of steam turbine girdle gaskets with diversified boundary dimensions.

Description

technical field [0001] The invention relates to the technical field of plate cutting equipment, in particular to a special bench shear for the shroud gasket of a steam turbine. Background technique [0002] The prior art uses table shears as equipment for cutting thin steel plates, and adopts a cutting table without gaskets. The existing defect is that it is mainly used in occasions where ordinary thin steel plates have no requirements for the accuracy of external dimensions. The cutting accuracy is low, and the size of the cut steel plates cannot be accurately controlled. And the appearance; the labor intensity of the operator is high, the work efficiency is low, the handle is too long, and it cannot be used when the operating space is limited. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a special bench scissors for steam turbine shroud gaskets; the structure is simple, the operation is convenient, the...
