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

shearing machine cylinder are widely used in Argentina，because of high work efficiency，long service life，smooth movement.So our company has designed shearing machine cylinder for customers from Argentina.

Introduction to shearing machine cylinder:

The definition of the minimum starting pressure of the shearing machine cylinder refers to the minimum working pressure of the shearing machine cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the shearing machine cylinder parts and the size of the sealing friction.

The machining accuracy of the shearing machine cylinder depends on the level of equipment, production technology and testing means. shearing machine cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

shearing machine cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Factors that should be considered when selecting the oil seal in the shearing machine cylinder: some specific factors should be taken into account when selecting the oil seal in the shearing machine cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: shearing machine cylinder diameter, piston rod diameter, piston rod and piston groove size, shearing machine cylinder working pressure, shearing machine cylinder movement speed, hydraulic system oil temperature and shearing machine cylinder working environment.

Answers to some questions about shearing machine cylinder:

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.
