Hydraulic Alligator Shear

Hydraulic Alligator Shear Introduction

●Hydraulic Alligator Shear suitable for all kinds of wire and cable, aluminum, stainless steel, plastic and other non-ferrous metal shear.Applicable to the steel industry, non-ferrous metals industry, scrap processing and distribution center (base) and renewable resource processing enterprises, scrapped car dismantling enterprises.

●And this Hydraulic Alligator Shear machine electric system consists of motor control circuit and action control circuit,which can be started and stopped at any position, and it is easy to realize overload protection.

●Hydraulic system is the central control system of the machine, which is mainly composed of oil pump, oil filter, valve block valve, oil tank and its accessories.

●According to the needs of use can choose a single, continuous operation.

●The equipment installation does not need anchor bolts to facilitate production or equipment layout adjustment

●Can be equipped with diesel engine as backup power supply.

Hydraulic Alligator Shear Technical Parameter

Hydraulic Components

（1）Relief valve 

The use of cartridge relief valve, used as a system of safety valve setting system pressure, the pressure adjustment can be carried out through the rotary valve handle, the machine set pressure is 15Mpa. 

（2）Solenoid directional valve

Model:SWH-G02-C6-20,Broken except or keep the valve when the valve is to rely on the electromagnet pull power to generate thrust manipulation of straight moving type reversing valve is used to control the hydraulic oil of the on-off and flow direction. 

Mainly by one or two solenoid valve and one or two of the reset spring, when the solenoid is energized, the valve core by a reset spring in initial position (pulse valve), the valve core 3 action by wet electromagnetic to achieve. 

When the electromagnet power, the electromagnet force by putting the effect in the spool 3 on, the rest position pushed to the working 

position by the liquid flow p to a and B to t through, or from P to B and a to t pass. When the solenoid Power, the spring on the valve returns to its rest position. The electromagnet is not energized can push the manual button to the spool movement.

Hydraulic Principle Description

(1)Air transfer

After starting the motor, high pressure oil through the oil pump, electromagnetic valve back to the tank, the system unloading。

(2)Pressure regulation  

According to the shear (or return) button, so that the shear cylinder shear in place (or return in place), the gradual rotation of the relief valve handle, the observation of the value of the pressure value of 15Mpa. 

Generally cut thin when the pressure can be slightly lower than this value.

(3)After shearing YV1, high pressure oil through the valve to enter the shear cylinder cavity, shear machine to achieve shear action.

(4)Return to power after the return of power YV2, high pressure oil through the valve into the cylinder before the shear cylinder, cylinder return.
