China metal plate rolling machine

The metal sheet rolling mill,as a key equipment for metal pressure processing,occupies a pivotal position in China's manufacturing industry.It can reduce the thickness and increase the length of metal billets through the rotational pressure of rolling mills,thereby obtaining metal sheets with the desired shape and properties.The following will provide a detailed introduction to the working principle of China's sheet metal rolling mill.
The basic structure of a rolling mill
The common metal sheet rolling mill in China is mainly composed of a working stand,rolling mill and its adjustment device,rolling mill bearings,rolling mill balancing device,rolling mill transmission device,frame,and lubrication and cooling system.
1.Working stand:The China metal plate rolling machine is the core support structure of the rolling mill,providing a stable working position for the rollers and withstanding the enormous pressure during the rolling process.
2.Rolls:divided into work rolls and support rolls.The work roll comes into direct contact with the metal sheet and rolls it;The support roller is used to support the working roller,reduce the deflection of the working roller,and improve the rolling accuracy.
3.Roller adjustment device:The Chinese metal sheet rolling mill can adjust the position of the rollers,including axial and radial movement,to control the thickness,width,and shape of the metal sheet.
4.Roller bearings:They can withstand rolling forces and ensure that the rollers can rotate flexibly,usually using rolling bearings or sliding bearings.
5.Roll balancing device:eliminates the gap between the rolls,prevents impact during rolling,and ensures the stability of rolling.
6.Rolling mill transmission device:The China metal plate rolling machine is composed of an electric motor,a reducer,a coupling,etc.,which provides rotational power for the rolling mill.
7.Rack:Connecting and fixing the various components of the rolling mill to form a cohesive structure.
Once the China metal plate rolling machine is bitten into the rolling mill,plastic deformation will occur in the deformation zone.Under the action of rolling force,the thickness of the metal sheet gradually decreases,the length gradually increases,and there may also be some changes in the width direction(widening).The process of plastic deformation is actually the process of slip and deformation of grains inside the metal.As rolling progresses,the grains of the metal sheet are elongated,broken,and recrystallized,thereby improving the microstructure and properties of the metal.For example,by controlling the rolling temperature and deformation degree,metal sheets can obtain fine grain structure,improve their strength and toughness.
Rolling force is the force exerted by the rolling mill on the metal sheet during the rolling process,and the Chinese metal sheet rolling mill is an important basis for the design of rolling mills and the formulation of rolling processes.The magnitude of rolling force depends on the material,thickness,width,degree of deformation of the metal sheet,as well as factors such as the diameter and speed of the rolling mill.During the rolling process,the rolling force is transmitted to the frame through the rolling mill,and then transmitted to the foundation through the frame.In order to ensure the normal operation and structural safety of the rolling mill,it is necessary to calculate and control the rolling force.
With the intelligent development of China's manufacturing industry,automation control technology has been widely applied in metal sheet rolling mills.By installing various sensors such as pressure sensors,displacement sensors,temperature sensors,etc.,various parameters during the rolling process can be monitored in real time,such as rolling force,roll gap,metal sheet thickness,temperature,etc.And these parameters are fed back to the control system,which automatically adjusts the position,speed,tension,etc.of the rolling mill according to the preset process parameters and rolling model.The China metal plate rolling machine realizes the control of the rolling process.
The working principle of China's sheet metal rolling mill involves multiple aspects of knowledge and technology,from the basic composition of the rolling mill to the mechanical principles of the rolling process,to the characteristics of different types of rolling mills and the application of automation control technology.Each link is interrelated and influences each other.With the continuous advancement of technology,China's sheet metal rolling mills will continue to develop towards efficiency,energy conservation,intelligence,and high precision,providing strong support for the upgrading and transformation of China's manufacturing industry.
