Bending center tells you how to maintain the machines hydraulic press brake

Today, DURMAPRESS introduces the bending center to tell you how to maintain the machines hydraulic press brake.

Center of bending, the bending machine is a kind of can be carried out on the thin plate bending machine, the structure mainly includes the bracket, workbench and clamping plate, workbench on the scaffold, workbench consists of base and the clamp, the base through the hinge is connected with the clamping plate, the base is composed of shell, the coil and plate, coil placed inside the shell of the sag, the depression at the top of the cover plate. When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping between the pressure plate and the base plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall, the operation is also very simple.

Bending machine is divided into manual bending machine, hydraulic bending machine and CNC bending machine. Manual bending machine is divided into mechanical manual bending machine and electric manual bending machine, hydraulic bending machine according to the synchronous way and can be divided into: torsion shaft synchronization, machine-hydraulic synchronization, and electro-hydraulic synchronization. Hydraulic bending machine according to the way of movement can be divided into: moving up, moving down.

Bending center, bending machine adopts steel welding structure, with enough strength and rigidity; Hydraulic upward transmission, the cylinder at both ends of the machine tool is placed on the slide block, directly drive the sliding work; The slider synchronization mechanism adopts torsional shaft to force synchronization; Mechanical block structure, stable and reliable; Slider stroke mobile quick adjustment, manual fine tuning, counter display; Oblique wedge type deflection compensation mechanism to ensure higher bending accuracy.

Before carrying out machine maintenance or wiping machine, the upper die should be aligned with the lower die and then put down and shut down until the work is finished. If it is necessary to start up or other operations, the mode should be selected in manual and ensure safety. Its maintenance content: hydraulic oil circuit, check the oil level of the tank every week, such as hydraulic system maintenance should also check, oil level lower than the oil window should be filled with hydraulic oil; The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25. The oil should be changed after the new machine works for 2000 hours, and the oil should be changed after every 4000 ~ 6000 hours. The oil tank should be cleaned every time the oil is changed. The system oil temperature should be between 35℃ and 60℃, not more than 70℃, if too high will lead to oil quality and accessories deterioration damage.

Filter, each time the oil change, the filter should be replaced or cleaned; The machine should be replaced if there is a related alarm or oil is not clean and other filter abnormalities. The air filter on the tank should be checked and cleaned every 3 months and expected to be replaced every 1 year. Hydraulic parts, clean hydraulic parts (substrate, valve, motor, pump, oil pipe, etc.) every month, prevent dirt into the system, can not use detergent; After a month of use of the new machine, check whether the bending of each oil pipe is deformed, if there is abnormal should be replaced, after two months of use, should tighten the connection of all accessories, this work should be shut down, no pressure system.
