1. Press brake machine is a device used to complete the overall bending and forming of sheet materials. After one stroke of the slider, the sheet is bent into a cross-sectional profile of a certain geometric shape. A relatively simple mold can be used to fold various shapes of workpieces, and multiple bending can also obtain various complex cross-sectional shapes.
2. In addition, if equipped with suitable molds, it can also be used for punching, shallow stretching, etc. The machine is widely used in aviation, aerospace, automobile, electronics, construction machinery, shipbuilding, railway vehicles, and other industries.
3. The HARSLE bending machine adopts a special CNC system for bending machines. In addition to the basic number of axes Y1, Y2, and X axes, a variety of CNC axis configurations can be combined according to user needs.
4.The CNC system can automatically realize the control of the running depth of the slider, the adjustment of the left and right inclination of the slider, the adjustment of the pressure tonnage, the adjustment of the running speed of the slider, as well as the front and rear adjustment of the back gauge, the left and right adjustment, the up and down adjustment, and so on. The bending machine can easily realize the actions of slide down, work advance, pressure holding, return, jog and stop in the middle, and complete multiple bending of the same angle or different angles in one feeding.
● Only trained workers should operate the press brake.
● The operator should read the manual carefully.
● Make sure you understand the details, structure, performance, and safety information of the CNC bending machine before you start using it.
● Before starting to use the hydraulic sheet metal press brake, please follow the safety information items.
● The operating manual of the press brake is very important. We need to keep the manual in a safe place so that it can be checked if necessary.
5 Tips for Hydraulic Press Brake Operation
Hydraulic bending machines are widely used in aircraft, automobiles, shipbuilding, electrical appliances, machinery, light industry, and other manufacturing industries.
So correct operation and simple use are very important. When using the machine, there are the following tips.
1. CNC bending machine operation
● Operators should always check all connecting bolts and fittings to ensure they are tightened before operation.
● The main parts of the machine, such as the frame, are all-welded structures.
● When using a CNC bending machine, the operator should check the welds frequently during operation.
● If a crack is found, the machine should be stopped immediately, and it can only be repaired by a technician before operation.
● The metal hydraulic press brake must be reliably grounded.
2. Backgauge of CNC bending machine
● The back gauge of CNC sheet metal bending is driven by a servo motor, which can achieve precise positioning.
● The back gauge of the Shenchong CNC hydraulic bending machine adopts an imported famous brand, and the back gauge can be manually fine-tuned.
● We need to regularly check the clearance between the lead screw and the nut, and re-tighten or replace the worn parts when the clearance is too large to ensure accurate positioning.
● Do not allow the operator to adjust the rear gauge fingers in front of the machine.
3. Upper and lower die operation of bending machine
● When using hydraulic sheet metal bending machines, we bend different materials, different plate thicknesses, plate widths, and lengths.
● The top tool and bottom die must therefore be selected correctly.
● When the plate thickness changes, the opening width of the die needs to be reselected.
● When bending short workpieces, the operator should place the sheet in the middle of the machine to avoid an unbalanced load.
● We often need to adjust and change the opening of the bottom mold, at this time we can use the lifting ring to turn or move the bottom mold to select the correct V-groove on the CNC bending machine bending mold.
4. CNC bending machine safety
● Do not operate the hydraulic press brake with a bending force exceeding the nominal force to avoid damage to the machine.
● Do not stick your hands or any part of your body into the mold area at any time,
● Never adjust anything behind the plunger from the front of the machine through the die area.
● The body should be kept away from the workpiece to avoid injury caused by the bending of the workpiece when the machine is running.
● When the CNC bending machine stops working, the gate must be kept at the bottom dead center.
5. Power supply safety of bending machine
To ensure the stability of the power supply, the following points must be paid attention to during the operation of the hydraulic press brake:
● The operator cannot weld on the machine, nor connect high power.
● We cannot use them as ground conductors.
● Make sure the machine's high powerpoint is stable and there is no high voltage circuit.
● The hydraulic CNC bending machine should be installed in a workshop without direct sunlight.
● For the operating environment of the hydraulic press brake, an environment with low humidity, little dust and good ventilation is preferred.
● Before using the CNC bending machine, we need to confirm whether the hydraulic system can prevent the machine from overloading the bending pressure to make the machine.
HARSLE CNC sheet metal bending machines all use electro-hydraulic proportional valves, which are imported from Germany or other European countries.
Therefore, the HARSLE hydraulic press brake can give the first warning when it is overloaded.
● The machine should be operated within the rated pressure range, otherwise a serious accident may occur.
● The compensation system under the hydraulic press brake die ensures higher bending accuracy.
● When we buy a bending machine, it is better to choose a machine with compensation. Shenchong metal bending machines usually have a compensation system.
