(Vietnam shearing machine cylinder,produced by Hebei Hengyu company）

shearing machine cylinder are widely used in Vietnam，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed shearing machine cylinder for customers from Vietnam.

Introduction to shearing machine cylinder:

The shearing machine cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure shearing machine cylinder can use 20 steel pipe, and the high pressure shearing machine cylinder can use 45 steel pipe.

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.

Classification of shearing machine cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

When the long-stroke shearing machine cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in shearing machine cylinder head seal damage, oil leakage, and piston sleep in the shearing machine cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the shearing machine cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about shearing machine cylinder:

When there is only one hole in the oil inlet and outlet of the hydraulic cylinder, will there be oil leakage?
It is a single acting oil cylinder. This oil cylinder is always driven by hydraulic oil in advance, and is generally pulled back by the spring at the bottom of the piston or the weight of the cylinder piston or the load. But either way, it has nothing to do with any internal leakage. Whether the oil is internally drained is related to the sealing and accuracy of the cylinder itself.

The difference between the overall cylinder and the separate cylinder of the truck?
The whole cylinder is cast in one piece, and such a cylinder generally does not leak oil. Split cylinder refers to two welded, easy to leak oil in the welding place, resulting in damage to the cylinder, or its body can not get up, many people do not use this kind of cylinder now.
