Italy shearing machine cylinder

(Italy shearing machine cylinder,produced by Hengyu Group)

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

Introduction to shearing machine cylinder:

shearing machine cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards shearing machine cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the shearing machine cylinder guide is determined by the length of the stroke. Check the strength of shearing machine cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the shearing machine cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

When the shearing machine cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the shearing machine cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The commonly used buffer structure of the shearing machine cylinder is composed of a piston boss and a shearing machine cylinder head groove. When the piston moves close to the shearing machine cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Answers to some questions about shearing machine cylinder:

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.

Why does the cylinder pop out of itself when it stops?
This situation has two possibilities, 1. There is more air in the system, so exhaust the gas. 2. The back pressure of the oil return is relatively large, check the oil return filter, check whether the cylinder has a rod cavity buffer is too tight, and choose a 3-position 4-way M-type valve for the reversing valve. In addition, after the shutdown, manually change the reversing valve back and forth several times, it should not rise out.
