Press brake is to use the equipped mold (general or special mold) to bend the cold metal sheet into various geometric cross-sectional shapes. The press brak can quickly realize the actions of sliding down, jogging, continuous, pressure holding, return stroke and halfway stop, and bend multiple elbows of the same angle or different angles in one feeding.
The press brake generally adopts a special CNC system for the bending machine. The coordinate axis of the bending machine has been changed from a single axis is developed to 12 axes, and the numerical control system can automatically realize the sliding depth control, the left and proper tilt adjustment of the sliding block, the front and back adjustment of the back stopper, the left and right adjustment, the pressure tonnage adjustment and the slider approaching speed adjustment so and on.
NC press brakes are two-axis programmable tools that use torsion bars for synchronization. NC, or Numerical Control, refers to the use of a numerical control system to manage
the machine's movements. NC press brakes typically employ pre-written numerical programs to control bending operations. These programs contain a series of coordinates and
motion instructions to determine the shape and bending angles of the workpiece. Operators must manually input these numerical programs, often using the machine's control
panel or an external computer. NC press brakes are generally less expensive than CNC press brakes but require more operator skill. NC press brake controllers can be programmed for complex bending sequences, such as those offered by Delem 41, E21, and Cyblec. They remain an accurate and cost-effective option.
The CNC press brake does not need to take special measures during the return (up) trip. In the fast-forward phase of the descending stroke, on the basis of parallel synchronization, two one-way throttle valves are used to eliminate the deviation caused by factors such as manufacturing quality, leakage, etc., and to ensure the downward movement with a certain synchronization accuracy.
When it enters the work advancement stage but has not touched the workpiece, two correction plunger cylinders installed on the workbench are used for further synchronization correction. Imagine that one side first comes into contact with the correction plunger, and the larger correction force slows down or stops the movement of that side until the other side catches up and contacts the correction post hydraulic and pneumatic plugs at the same time. The correction force can be set by the overflow valve and read by the pressure gauge. Practice has shown that the synchronization effect is very obvious, this is because various asynchrony factors can be ignored compared with the correction force. In order to make full use of the capacity of the machine, the overflow valve 3 should be unloaded after a period of time.
The Hydraulic Press Brake includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil It is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate.
When in use, the wire is energized to the coil, and after energization, an attractive force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and it can also process workpieces with side walls. Hydraulic press brakes are the safest and more controllable than a mechanical brake. They generally allow for multiple speed settings. Hydraulic also allows for more precision bends, providing greater control when inching down and getting set for a job.
Hydraulic Press Brake Instructions
Step on the foot switch to start bending. Unlike the shearing machine, the bending machine can be released at any time, and the bending machine will stop when the foot is released, and continue to go down after stepping on it.
First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start, so that you can hear the sound of the oil pump turning. (The machine does not work at this time)
Stroke adjustment, the use of the bending machine must pay attention to the adjustment of the stroke, and it must be tested before bending. When the upper die of the bending machine goes down to the bottom, there must be a gap of plate thickness. Otherwise it will cause damage to the mold and machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.
For the selection of the bending notch, generally a notch with a width 8 times the thickness of the plate should be selected. If you bend a 4mm sheet, you need to choose a notch of about 32.
There are generally electric quick adjustments and manual fine adjustments for the adjustment of the back gauge, and the method is the same as that of the shearing machine.
