Abstract

The hydraulic steel bar cutting machine includes machine base, cutter seat, hydraulic cylinder with piston rod, piston rod guiding seat, cutter fixed on the piston rod, sealing part between the piston rod and the hydraulic cylinder; motor driven oil pump connected via oil divider to the front cavity and the back cavity of the hydraulic cylinder, oil returning pipe connected between oil divider and oil tank; electromagnetic change-over valve with two electric magnets to control the front cavity and the back cavity separately; two stroke switches for limiting the range of the piston rod and corresponding touch blocks on the piston rod; and one circular control mechanism comprising the two stroke switches and the two electric magnets.

Description

(1) Technical field [0001] The invention relates to a hydraulic steel bar cutting machine. (2) Background technology [0002] There are two types of steel bar cutting machines sold and used in the market: manual and motorized. Manual steel bar cutters generally cut steel bars through the action of leverage, which has low work efficiency and high labor intensity, and it is difficult to cut larger steel bars. Motorized steel bar cutting machine generally cuts steel bars under the action of motor, belt, gear and eccentric shaft transmission, which is inconvenient to operate, large in size, inconvenient in transportation, loud in noise, strong in vibration, easy to wear on gears, easy to wear on belts, etc. (3) Contents of the invention [0003] The invention aims to solve the shortcomings of low working efficiency of manual steel bar cutting machine and large volume and inconvenient operation of motorized steel bar cutting machine, and provides an electrohydraulic steel bar ...
