Analysis Of Control Components Of Shearing Machine

Sep 27, 2017

Many types of shears, according to different classification criteria, can be divided into different types, the following to talk about the classification of Shearing Machine, as follows:

(1) by cutting method can be divided into cross shear and slitting.

(2) according to the temperature of the shear plate is divided into hot shear and cold shear.

(3) According to the Shearing Machine drive method is divided into mechanical shear, hydraulic shear and pneumatic shear.

(4) according to the way the frame is divided into open shear and closed shear; according to the type of shear plate is divided into billet shears, steel shears, shears and pipe Shearing Machine

Shear control components (ie, various types of hydraulic valves) in the hydraulic system to control and conditioning the liquid pressure, flow, and bias. According to the control of the performance of the substandard, the hydraulic valve can be divided into pressure control valve, flow control valve and bias control valve. Pressure relief valve can be divided into relief valve (safety valve), pressure relief valve, the order valve, pressure relay, etc .; flow control valve contains throttle valve, regulating valve, diverter valve, To the valve, hydraulic check valve, shuttle valve, valve and so on. According to the control method can be divided into non-hydraulic valve control valve, the value of control valve and proportional control valve.

What about the shearing machine when shearing the shearing? When cutting the rolling, the cutting edge in the direction of the rolling movement of the instantaneous speed v if less than the moving speed v0, the cutting edge will hinder the movement of the rolling, will make the rolling bending, and even produce rolling knife accident The On the other hand, if the instantaneous velocity v of the shearing edge in the direction of the shearing is much larger than that of the rolling movement velocity v0, a greater tensile stress will be produced in the rolling, which will affect the shear quality of the workpiece Increase the impact load of the shearing machine
