(Bolivia shearing machine cylinder,produced by Hengyu Hydraulic Cylinder Factory）

shearing machine cylinder are widely used in Bolivia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed shearing machine cylinder for customers from Bolivia.

Introduction to shearing machine cylinder:

shearing machine cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the shearing machine cylinder head itself is the guide sleeve of the piston rod, the shearing machine cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the shearing machine cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

shearing machine cylinder can not drive the load troubleshooting: oil pressure is too low. shearing machine cylinder selection specifications are too small. Leakage in shearing machine cylinder or associated hydraulic system element.

The shearing machine cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

When producing oil shearing machine cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about shearing machine cylinder:

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.
