2018 Ultimate Version BR75 4-roll Section Bending Machine Specifications

Basic performance

1, mechanical technical requirements

1.1 The equipment is small in size, compact and reasonable in structure, reliable in performance, convenient in operation and maintenance, and its bending accuracy meets industry standards;
1.2, with profile pre-bending function, once the material is not turned around to complete the bending of the workpiece;
1.3. Structure: Four-roller arc type.
1.4. Drive master type: All three work rolls are main drive rollers, which are realized by hydraulic motors and gears. The position of the upper roller is fixed, and the two lower rollers are lifted and driven by hydraulic pressure. The arc can be lifted and moved around the fixed rotation center. The screen shows that the work roll is provided with a supporting roller and a correcting guide device, so as to ensure the rolling quality of the asymmetric cross-section profile;
1.5, roller correction roller can achieve three movements:
A. You can do lifting exercises.
B. It can perform arc lifting movement with the lower roller at the same time;
C. It can do rotary motion at the same time, the digital display of motion state, eye-catching and intuitive, at any time to observe the forming quality of the profile in the rolling process;
1.6. It is equipped with an independent mobile console, which is easy to operate and use.
1.7. Bed: The bed adopts Q235 steel plate welding structure, and the internal stress is relieved by annealing. The strength and rigidity meet the requirements of national and industry standards;

2.4. Each input and output port of the hydraulic system is required to have a corresponding detection point to facilitate maintenance and troubleshooting. The oil pump adopts the lower type, positive pressure oil absorption. At the same time, the filter is equipped with a liquid level gauge and a liquid thermometer. The hydraulic station is required to be independent of the stand for ease of maintenance and protection from heat sources.
2.5 The system shall be manufactured in strict accordance with national standards and standards. The bending radius shall be reasonable, and not less than 900. It shall be oversimplified and sleek. The shock-absorbing movable pipe clamp shall be reasonably arranged to effectively avoid shock and vibration and ensure that the hydraulic pipeline is free of shock and vibration.
2.6. The system design should fully consider the high efficiency and energy saving, reduce power waste and reduce the heat source.
2.7. Provide instructions for the common fault phenomena and remediation methods of the bending machine hydraulic system.

2.8. The main electrical components of strong power are selected by Chint quality products, which have the characteristics of long service life and long time without failure. The electrical system is equipped with safety protection devices, such as overcurrent, overheating, overload protection and various actions of the hydraulic system. Inter-safety interlock protection device.
