Shearing machine for steel grating plate

Abstract

The invention discloses a shearing machine for a steel grating plate. The machine comprises a cutter holder seat, a cutter assembly, a supporting seat, a transverse adjusting assembly and a lead screwadjusting assembly, wherein the cutter assembly comprises an oil cylinder, an upper cutter which is driven through the oil cylinder, a guide seat for guiding the upper cutter, a slideable lower cutter, and a lower cutter guide rail which is arranged on the cutter holder seat; the oil cylinder and the guide seat are fixed to the cutter holder seat; the supporting seat comprises a transverse guiderail, a supporting plate and a first vertical guide rail; the transverse adjusting assembly is connected to the cutter holder seat; the lower end of the lead screw adjusting assembly is in contact with the lower cutter. The shearing machine for the steel grating plate is simple in structure, stable to work, and accurate in cutting; the upper cutter is used for pressing and positioning the steel grating plate and can be matched with the lower cutter to cut the steel grating plate; few working steps are carried out, so that the production and processing can be quickly performed; and meanwhile, transverse gaps of the upper cutter and the lower cutter can be adjusted; and the cutting height of the lower cutter can be adjusted.

Description

technical field [0001] The invention relates to the technical field of shearing, in particular to a steel grating shearing machine. Background technique [0002] At present, in the field of steel grating processing and production, the steel grating produced needs to be cut and processed. The cutting machine is a necessary equipment. The existing cutting machine generally adopts the motor saw blade type, which is cut by the saw blade. Cutting will produce a lot of noise and metal shavings, which will affect the health of workers. The saw blade has a certain thickness, and the cutting process will cause waste of materials. Moreover, the saw blade is made of special alloy material, which is very expensive. It will also cause damage to the saw blade. The service life of the saw blade is only a few months, and frequent replacement of the saw blade will result in increased processing costs and low production efficiency. Therefore, the current steel grating cutting machine cannot m...

It will also cause damage to the saw blade. The service life of the saw blade is only a few months. Frequent replacement of the saw blade will result in increased processing costs and low production efficiency. Therefore, the current steel grating cutting machine cannot meet the needs

[0003] The existing Chinese Patent Publication No. CN101219487A is a steel grating shearing device, which is composed of a frame, a lifting device, a vertical shaft and a holder. The lower part of the lifting device is fixed with a cutter, and the cutter can be inserted between two rows of holders. And the bottom edge of the triangle can protrude beyond the lower edge of the holder. The head of the tool is triangular. There can be one or more tools. There is a gap between adjacent tools. The lifting device is hydraulic or electric; However, it has the following disadvantages. It needs to use the clamper to hold the steel grating. The structure is complex, and the operation is cumbersome, and the work takes a long time. , it is not suitable for running water shear trimming of welded steel grating
