Shearing machine for steel grating plate

Abstract

The invention discloses a steel grating shearing machine, which includes a knife holder seat, a cutter assembly, a support seat, a lateral adjustment assembly and a screw adjustment assembly; the cutter assembly includes an oil cylinder, an upper cutter driven by the oil cylinder Knife, the guide seat for the guide of the upper cutter, the slidable lower cutter and the lower cutter guide rail arranged on the knife rest seat, the oil cylinder and the guide seat are all fixed on the knife rest seat; the support seat It includes a horizontal guide rail, a support plate and a first vertical guide rail, the horizontal adjustment assembly is connected to the knife rest seat; the lower end of the screw adjustment assembly is in contact with the lower cutter. The invention is simple in structure, stable in operation, and fine in cutting. The upper cutter is used to press the steel grating to position the steel grating, and cooperates with the lower cutter to cut the steel grating. The working steps are less, which is conducive to rapid production Processing, at the same time, the transverse clearance of the upper cutter and the lower cutter is adjustable, and the cutting height of the lower cutter is adjustable.

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...

[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. 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
