Description

Quick material cutting machine Technical Field The invention relates to the technical field of material cutting machine manufacturing, in particular to a rapid material cutting machine. Background The material cutting machine is a mechanical processing device which uses a driving device (mostly adopts the reciprocating motion of a piston rod or a connecting rod) to drive a shearing mechanism to squeeze and cut the raw material (generally, a long-strip columnar material). The small-sized material cutting machine adopts an air cylinder as a power source of the shearing mechanism, and the air cylinder has the characteristic of high response speed, but has limited output pressure due to the compressibility of gas, and can only be used for discharging thinner raw materials. For thicker raw materials, a large-sized cutting machine is needed to carry out blanking processing, and the large-sized cutting machine mostly adopts a hydraulic cylinder as a power source of a shearing mechanism. The oil inlet and the oil outlet of the traditional hydraulic oil cylinder are the same, namely the same oil port is used as the oil inlet and the oil outlet, the oil inlet pressure is not only related to the pressure supply capacity of a hydraulic system, but also related to the caliber of the oil inlet, and under the same pressure supply capacity condition, the larger the caliber of the oil inlet is, the smaller the oil inlet pressure is, otherwise, the smaller the caliber of the oil inlet is, and the oil inlet pressure is lack. Because the oil inlet and the oil outlet are the same, in order to ensure the oil inlet pressure, the diameter of the oil inlet cannot be too large, but the smaller diameter of the oil inlet can lead to slow emptying speed of hydraulic oil (further to slow resetting speed), and the two are contradictory two aspects, so that the existing hydraulic oil cylinder cannot ensure the output pressure and the resetting speed, and further the material breaking speed of the large-scale material breaking machine is slow, the production efficiency is influenced, and the structure of the existing material breaking machine needs to be further improved. Disclosure of Invention The invention aims to overcome the defects, and discloses a quick material cutting machine which has reasonable structure, high automation degree, quick material cutting speed and quick resetting of a cutting mechanism.
