How to Use a Press Brake (Beginner's Must-See Guide)

Press Brake

Introduction to the Use of Press Brake

A brief introduction to processing Q235 sheet according to ordinary Hydraulic Press Brake:

1. The first is to 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 rotation of the oil pump. (The machine does not work at this time)

2. Stroke adjustment, the use of the bending machine must pay attention to the adjustment of the stroke, and be sure to test the car 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 the machine. The adjustment of the stroke also has electric quick adjustment and manual gastric adjustment.

3. For the selection of the bending notch, it is generally necessary to select a notch with a width of 8 times the thickness of the plate. For bending 4mm sheet, you need to choose a notch of about 32.

4. The rear gauge adjustment generally has electric quick adjustment and manual fine adjustment, the method is the same as that of the shearing machine.

5. Press the foot switch to start bending. The bending machine is different from the shearing machine. It can be released at any time. When the foot is released, the bending machine stops and continues to descend.

Press Brake Maintenance and Maintenance

Before maintenance or cleaning of the machine tool, the upper die should be aligned with the lower die, then put down and shut down until the work is completed. If you need to start the machine or other operations, you should select the manual mode and ensure safety. Its maintenance content is as follows:

1. Hydraulic oil circuit

a. Check the oil level of the fuel tank every week. If the hydraulic system is repaired, it should also be checked. The oil level should be filled with hydraulic oil if the oil level is lower than the oil window;

b. The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25;

c. The oil should be changed after the new machine works for 2000 hours, the oil should be changed after every 4000-6000 hours of operation, and the oil tank should be cleaned every time the oil is changed;

d. The oil temperature of the system should be between 35°C and 60°C, and should not exceed 70°C. If it is too high, the oil quality and accessories will be deteriorated and damaged.

2. Filter

a. Every time the oil is changed, the filter should be replaced or thoroughly cleaned;

b. The machine tool has related alarms or the oil quality is not clean and other filters are abnormal and should be replaced;

c. The air filter on the fuel tank should be checked and cleaned every 3 months, preferably every 1 year.

3. Hydraulic components

a. Clean hydraulic components (substrates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system, and do not use detergents;

b. After the new machine is used for one month, check whether the bending of each oil pipe is deformed. If there is any abnormality, it should be replaced. After two months of use, the connections of all accessories should be tightened. When this work is performed, the system should be turned off. The pressure hydraulic bending machine includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. 

The worktable is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate.

When in use, the coil is energized by the wire, and after the electricity is energized, the pressure plate is gravitationalized, 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 pressing plate can be made into various workpiece requirements, and the workpiece with side walls can be processed.
