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

Introduction to rolling mill cylinder:

The advantages and disadvantages of the rolling mill cylinder: the surface of the rolling mill cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the rolling mill cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

When producing oil rolling mill 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.

The pressure of the sliding surface of the rolling mill cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the rolling mill cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

At the rated pressure, the thrust of the rolling mill cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the rolling mill cylinder is related to the diameter of the rolling mill cylinder, but not to the stroke of the rolling mill cylinder. Moreover, the larger the rolling mill cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the rolling mill cylinder.

Answers to some questions about rolling mill cylinder:

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.
