(Tanzania rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Tanzania，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed rolling mill cylinder for customers from Tanzania.

Introduction to rolling mill cylinder:

The method of sleeve rolling mill cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the rolling mill cylinder can be significantly improved by rolling in the finishing of the inner holes of the rolling mill cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

If the rolling mill cylinder slips or crawls, please check whether there is astringency inside the rolling mill cylinder, because the internal parts of the rolling mill cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the rolling mill cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the rolling mill cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

When the oil pressure of the rolling mill cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

In use, the rolling mill cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the rolling mill cylinder.

Answers to some questions about rolling mill cylinder:

How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
