Here's a simple introduction to processing Q235 sheet metal using a standard hydraulic bending machine:
1. First, connect the power supply. Turn on the key switch on the control panel, then press the oil pump start button.
2. Stroke adjustment: Stroke adjustment is crucial for bending machines. A test run is always necessary before bending. When the upper die descends to the bottom, a gap equal to the sheet thickness must be maintained. Otherwise, damage to the die and machine will occur. Stroke adjustment can be done electrically for quick adjustment or manually for fine-tuning.
3. Bending groove selection: Generally, a groove width 8 times the sheet thickness should be selected. For example, when bending a 4mm sheet, a groove of approximately 32mm is needed.
4. Back gauge adjustment: Generally, there are electric quick adjustments and manual fine-tuning options, similar to shearing machines.
5. Press the foot pedal to start bending. Unlike shearing machines, bending machines can be started at any time. Releasing the foot pedal stops the bending machine; pressing it again continues the downward movement.
