bending machine

The types of rolling machines vary depending on the field of use. Divided by the number of rolls, it is divided into three roll plate rolling machine and four roll plate rolling machine. The three roll rolling machine is divided into symmetrical three roll rolling machine, horizontal downward adjustment three stick rolling machine, curved downward adjustment rolling machine, upper roll all-around three roll rolling machine, and hydraulic CNC rolling machine. From the perspective of transmission, it can be divided into mechanical and hydraulic types. In terms of the development of plate bending machines, the upper roller universal type has fallen behind, the horizontal downward type is slightly advanced, and the curved downward type is relatively high-level.
The three roll plate rolling machine has 1. mechanical type 2. hydraulic type
1. Mechanical three roll plate rolling machines are divided into symmetrical and asymmetrical types.
Performance characteristics of the mechanical three roll symmetrical plate rolling machine: The structural type of the machine is a three roll symmetrical type. The upper roll performs vertical lifting and lowering motion at the midpoint symmetrical position of the two lower rolls, which is obtained through the transmission of a screw and worm. The two lower rolls perform rotational motion, and the output gear of the reducer meshes with the lower roll gear to provide torque for the rolled plate. The disadvantage of this machine is that the end of the board needs to be pre bent with the help of other equipment.
The main features of the mechanical three roll asymmetric plate rolling machine are as follows: the structure of the machine is a three roll asymmetric type, with the upper roll as the main transmission and the lower roll moving vertically to clamp the plate. The lower roll gear meshes with the upper roll gear and serves as the main transmission; The edge roller performs tilting and lifting motion, with dual functions of pre bending and coiling. Compact structure, easy to operate and maintain.
2. Hydraulic type
The main features of the hydraulic three roll symmetrical plate rolling machine are: the upper roll of the machine can be vertically lifted and lowered, and the hydraulic transmission for vertical lifting is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; The lower roller is driven to rotate, and the gear mesh is output through a reducer to provide torque for the rolling plate. The lower part of the lower roller has a support roller that can be adjusted. The upper roller has a drum shape, which improves the straightness of the product and is suitable for cans with various cross-sectional shapes of ultra long specifications.
For the upward adjustment symmetrical three roll plate rolling machine, metal sheets can be rolled into circular, curved, and conical workpieces within a certain range. The two lower rolls of this model are the driving rolls, and the upper roll is the driven roll. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure, and machinery manufacturing industries.
Suitable for bending deformation of metal sheets, it can roll circular, curved, and conical workpieces within a certain range, and has pre bending function at the end of the sheet. The two lower rollers of this model are active rollers that can move horizontally, and the upper roller is a passive roller that can move up and down. The movement methods include mechanical and hydraulic, and the transmission shafts are connected by universal couplings.
