Abstract

The invention discloses a punching shear type pipe cut-off device with double oil cylinders, and relates to the field of cutters. The device adopts a horizontal oil cylinder and a perpendicular oil cylinder to carry out longitudinal and transverse punching shear on workpieces in sequence, so that the problems of large noises and many cuttings during cut-off of the workpieces with large diameters and relatively thick pipe walls are solved. Meanwhile, inner and outer pairs of moulds are matched to achieve effect of a cut-off tool, and the workpieces are guaranteed to be not deformed during cut-off. The device is high in production efficiency, relieves the labor intensity of a worker, and improves cutting precision on workpieces of different specifications.

Description

technical field [0001] The invention relates to the field of cutting machines, in particular to a double-cylinder punching and shearing type pipe cutting device. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development. my country's modern industry is gradually developing in the direction of conservation, energy saving, emission reduction, and low carbon. Our country is one of the countries with the earliest mechanical development in the world. The machinery industry is the basic industry for the development of our national economy. The development of various industries in the national economy depends on the equipment provided by the machinery industry. In the machining process, the cutting machine is a processing tool for cutting plates. The cutting machine can cut the pipe int...
