1. scope of application
the plate rolling machine will pass the flat metal plate through its work roll, with the help of the downward pressure of the upper roll and the rotary movement of the lower roll, so that the metal plate will undergo multiple continuous bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed) to produce permanent plastic deformation, which will be rolled into the required cylinder, cone or part of them. plate rolling machine is one of the main equipment in petrochemical, boiler, motor, shipbuilding and machine manufacturing industries.
2.specification
three roll bending machine and four roll bending machine
3.product introduction
the types of plate rolling machines are different due to different fields of use. the number of rolls is divided into three roll plate bending machine and four roll plate bending machine. the three roll plate bending machine is also divided into symmetrical three roll plate bending machine, horizontal downward adjustment three roll plate bending machine, arc downward adjustment three roll plate bending machine, upper roll universal three roll plate bending machine and hydraulic numerical control plate bending machine. it is divided into mechanical type and hydraulic type in terms of transmission.
nhi has a long history in designing and manufacturing the coiling machine, mainly including the following four series of products: 3wbj ～ sd three roll upper adjustment symmetrical mechanical coiling machine, 3wbj ～ xf three roll lower adjustment asymmetrical mechanical coiling machine, 4wbj ～ xf four roll lower adjustment asymmetrical mechanical coiling machine, 3wby ～ sf three roll upper adjustment asymmetrical hydraulic coiling machine. these four series of products are complete in variety and specification, simple in structure, economical and durable, and easy to maintain, which can meet the needs of users. our company can also design the rolling machine beyond the above series for users according to the technical parameters negotiated by both parties, and sincerely serve users.
