When purchasing a Hydraulic guillotine shearing machine, many factors need to be considered, and many users only consider the impact of price because they do not understand it. Many factors affect our purchase of the hydraulic shearing machine. It is very important to choose a good factory. China hydraulic guillotine shearing machine manufacturers are the world's largest manufacturers of hydraulic shearing machines and sell hydraulic shearing machines all over the world every year.
Hydraulic Shears Have Extremely High Shearing Accuracy
The rear guide rail of the hydraulic guillotine shearing machine manufacturer produced by China hydraulic guillotine shearing machine manufacturers is supported by 4 large bearings, and the front guide rail is pressed by 2 bearings with compression springs behind them so that there is no gap between the front and rear guide rails. Clearance, the combined accuracy error of clearance and edge clearance are kept below 4 wires, so the sheared material is smoother and free of burrs.
The tool holder of the hydraulic shearing machine moves in a vertical straight line relative to the lower blade to ensure that the shearing sheet is less twisted and deformed and the straightness is more accurate. The hydraulic gate shearing machine is not easy to bend because the oil cylinder, the tool holder, and the blade are in the same line and move perpendicular to the lower edge. The winding and iron core of the linear motor are directly exposed to the air so that the heat can be removed from the air in time, and the temperature will not rise too high even if it runs for a long time.
Hydraulic Guillotine Shearing Machine Hydraulic Oil Requirements
Generally, the shearing machine produced by China hydraulic guillotine manufacturers must first have good anti-oxidative stability. Oxidative stability refers to the ability of the oil to resist chemical reactions with oxygenates when the temperature of the oil increases. Preliminary practice by China hydraulic guillotine shearing machine manufacturers shows that for every 10°C increase in oil temperature, the chemical reaction rate increases approximately twice.
The shearing machine hydraulic oil with good oxidation resistance and stability is not easy to oxidize and deteriorate when used for a long time, which can ensure the normal circulation of the hydraulic oil.
Hydraulic oil should have good anti-wear and lubricity. The purpose is to reduce mechanical friction, so the shearing machine produced by China hydraulic guillotine shearing machine manufacturers ensures the system's service life and maintains a proper viscosity.
The specific use depends on the working pressure of the hydraulic system of the shearing machine, the operating temperature, and the movement speed of the actuator. High viscosity should be selected for high pressure and high temperature, and low density should be chosen for high-speed motion.
Good viscosity and temperature. Viscosity temperature refers to the degree to which the thickness of the oil changes with temperature, which is usually expressed by the viscosity index. Good demulsibility and anti-foaming properties. Emulsification resistance refers to the ability of the oil to be mixed with water and become an emulsion after agitation, from which water is separated.
The anti-foaming property refers to the power of the oil to be combined with air and stirred to form an emulsion, and the air bubbles can be separated from the oil. After mixing with water or air, the volume modulus of the oil is reduced, the compressibility is increased, and the hydraulic components of the Hydraulic guillotine shearing machine are slow to act and are prone to shock and vibration.
Types Of Production Shears
The shearing machine equipment produced by China hydraulic guillotine shearing machine manufacturers or Maanshan Xiyuan Machinery Technology Co., Ltd. is better. Generally, the Electric shearing machine and Hydraulic guillotine shearing machine produced by the hydraulic guillotine shearing machine factory are very good from the outside. An indistinguishable, Hydraulic guillotine shearing machine can only be judged from some details and inner parts.
In contrast, the structure of the Electric shearing machine is relatively simple, so its installation and maintenance are also more convenient. Moreover, the tool holder itself is arc-shaped, and the point contact of the arc ensures the straightness of the sheared material. In contrast, the Hydraulic guillotine shearing machine tool holder moves in a vertical straight line relative to the lower blade to ensure the shearing of the sheet. Less distortion and more accurate straightness.
There are differences in both structure and operation. The QC12K 4x3200 CNC Hydraulic Swing Beam Shearing Machine With E21S produced by China hydraulic guillotine shearing machine manufacturers has a fixed angle, and the sheer speed cannot be adjusted; Hydraulic guillotine shearing machine can By adjusting the oil volume of two engineering oil cylinders connected up and down in series in the closed cavity, it can be quickly adjusted to realize angle adjustment.
Another point is the QC11K CNC Guillotine Shearing Machine With E21S produced by China hydraulic guillotine shearing machine manufacturers. The hydraulic system cylinder of the Electric shearing machine adopts a similar type, and the tool rest is mechanically forced to synchronize; Hydraulics are automatically synchronized.
Quality Assurance Of China Hydraulic Guillotine Shearing Machine Manufacturers
The existing shearing machine products are mainly hydraulic shearing machines and CNC shearing machines. In the process of use, ensuring the quality of shearing is very important. Most China hydraulic guillotine shearing machine manufacturers naturally have their own set of metrics. Oxygen buffer is the oxygen leveling effect on the scissors cutting seat.
Due to the tight air leakage, the leveling effect is greatly reduced, which affects the working condition of the Hydraulic guillotine shearing machine. The impact on the cutting edge of the Hydraulic guillotine shearing machine is very, very large. The sensation increased.
2.The air vent part of the system is the lower cover of the cylinder, the seal between the shaft and the hole; the original sealing ring is the shaft sealing ring 35, that is, 50 × 35 × 10, which is placed in the spot of the lower cover of the cylinder and is pressed with a retaining ring for the hole. The existing national standard product 35 is: 43×35×10, and the outer diameter differs by 7mm.
In the implementation process, the richness of the steel sleeve must be appropriate so that the retaining ring can be installed and the steel sleeve can be pressed tightly without leakage of the O-ring. China hydraulic guillotine shearing machine manufacturers provide consulting services for customers to send machine tools, which is convenient for consultation. The above is the introduction of 中国液压断头台剪板机制造商. I hope it will be helpful to you.
