4 m bending machine bending machine comprises a frame, the table and the clamping plate, the table is placed on the bracket, and the table plate constituted by the base, connected to the base by a hinge and clamp plate, the seat shell from the base, the coil and the lid the inner plates, the coil is placed inside the seat shell recess, the recess is covered with the top cover by wire to the coil is energized, the pressure plate against gravitational energized after use, in order to achieve sheet sandwiched between the platen and the base. As a result of electromagnetic force grip, making the plate can be made into a variety of workpieces requirements, but also to have the sidewalls of the workpiece processing, the operation is very simple.? 4-6 meters use a bending machine, the first power, Open the key switch on the control panel, press the pump start, so you hear the sound of a rotary pump. (At this point the machine does not move) 2, stroke adjustment, bending machine must be taken to adjust the trip, be sure to test before the bend. Bending machine at the bottom of the mold down to make sure there is a gap thickness. Otherwise, it will mold and machine damage. Stroke adjustment is also quick to adjust electric and manual adjustment stomach. 3, bending notch choice, and to select the slot thickness 8 times the width. 4mm sheet metal, such as bending, need to select about 32 notches. 4. After the block adjustment are generally quick to adjust electric and manual fine-tuning, the same way shears. 5, press the foot switch start bending, bending machines and shears 4-6 m different, you can always release, release the foot bending machine will stop, continue down the step.
