Energy-saving quick steel scrap shearing hydraulic loop system

Abstract

The invention discloses an energy-saving quick steel scrap shearing hydraulic loop system. The energy-saving quick steel scrap shearing hydraulic loop system comprises an oil pump, an oil tank, a shearing cylinder and a material pressing cylinder; a reversing valve is arranged between a rodless cavity of the material pressing cylinder and a rod cavity of the shearing cylinder; when the valve coreof the reversing valve is in a lower position, the rod cavity of the shearing cylinder and the rodless cavity of the pressing cylinder is communicated; when the valve core of the reversing valve is inan upper position, the communication between the rod cavity of the shearing cylinder and the rodless cavity of the material pressing cylinder is blocked, the rodless cavity of the material pressing cylinder is closed, and the rod cavity of the shearing cylinder is communicated with the oil tank; two-way switch valves are arranged between the rod cavity of the material pressing cylinder and the oil pump, and between the rod cavity of the material pressing cylinder and the oil tank; a two-way switch valve is arranged between a rod cavity of the material pressing cylinder and a rodless cavity ofthe shearing cylinder; a two-way switch valve is arranged between the rod cavity of the shearing cylinder and the oil pump; and two-way switch valves are arranged between the rodless cavity of the shearing cylinder and the oil pump, and between the rodless cavity of the shearing cylinder and the oil tank. According to the system, the hydraulic loop is optimized, so that linkage between the material pressing cylinder and the shearing cylinder is realized.

Description

technical field [0001] The invention relates to the technical field of scrap steel shears, in particular to a hydraulic circuit system of steel shears. Background technique [0002] The working conditions of the hydraulic scrap shear hydraulic system currently used in production are: the pressing cylinder goes down and compresses → the shearing cylinder goes down to cut → the shearing cylinder goes up and resets → the pressing cylinder goes up and resets, the two cylinders act successively, and only one cylinder works After the action is over, the other cylinder can act, the time between working conditions is long, the cutting frequency is low, and the production efficiency is low. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides an energy-saving fast hydraulic circuit system for scrap steel shearing, which has solved the above-mentioned technical problem of low successive action efficiency of the pressing ...
