What Kind of Lubricant Should Be Used for the Plate Bending Machine?


When using the roll plate bending machine, it is generally necessary to add lubricating oil at intervals. Only under the action of lubricating oil can the equipment have a better lubricating effect during use. Then the plate rolling equipment such as 3 roll or 4 roll plate roller should be in operation. What kind of lubricating oil should be used?


Ⅰ. What is the 3 roll plate bending machine?


The three roller bending machine has mechanical and hydraulic type; the mechanical 3 roll plate bending machine is divided into symmetrical and asymmetrical. Sheet metal can be rolled into circular, arc and conical workpieces within a certain range. The 3 roll plate bending machine is suitable for the bending deformation of metal plates. It can roll circular, arc and conical workpieces within a certain range, and has the function of pre-bending the end of the plate. Hydraulic three roller bending machine is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.


Ⅱ. The lubricating oil that should be used for the 3 roll plate bending machine


1. The lubricating oil selected first needs to have good viscosity and good temperature resistance. Because the viscosity of the lubricating oil is related to the starting performance of the equipment and the degree of wear of the parts, and the consumption of fuel and lubricating oil as well as the loss of power will also be affected to some extent. When the viscosity of the oil is too large, the fluidity is often relatively poor, so when it enters the friction surface, although its cooling performance will be poor, it will have good sealing performance when it is lubricated; then When the viscosity is too small, there is no way to secure the oil film, so the sealing performance of the friction surface is relatively poor, and the wear of the 3 roll plate bending machine during operation is relatively large, which leads to the 3 roll plate bending machine. Power drops during use. Therefore, when choosing lubricating oil, its viscosity is too large or too small are both not good.


2. You should choose to use cnc plate roller lubricating oil with good cleaning and dispersing function. Because sludge and other dirt appear in the lubrication system, it will be separated from the oil, which will cause the oil filter and oil holes to be blocked during operation, and also affect the fluidity of the oil, piston rings, fuel consumption, etc. Therefore, it is generally necessary to add a cleaning and dispersing agent to the lubricating oil. After understanding what kind of lubricating oil should be used for the three-roll rolling machine, when choosing lubricating oil, you can choose a better quality one with nice lubricating effect during operation.
