Maintenance e21 press brake from which aspects

E21 press brake mold includes a bracket, a workbench and a clamping plate. When used, the wire is energized to the coil, and after energized, the pressure plate produces gravity, so as to achieve the clamping of the plate and the base between the plate and the plate. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece can be processed on the side wall, the operation is also very simple. According to the ordinary e21 press brake machine die processing Q235 sheet to do a simple introduction:

1. First, switch on the power supply, turn on the switch on the control panel, and then start the oil pump, so that you can hear the rotating sound of the oil pump (the machine does not move at this time).

Preparation before Starting

1. Guide rail, rear stopper and other concentrated oil supply moving parts should be regularly refueled;

2. Check the cleanliness and damage of the mold, and deal with any abnormality in time;

3. Check the parallelism of rear stopper and the tension of driving belt.

Boot Procedure Tutorial

1. Follow the operation steps and operate the machine correctly;

2. When the machine tool is running, stop the inspection immediately if there is any abnormal situation. Refer to the relevant troubleshooting methods in the "Training Manual" for troubleshooting;

3. The machine should be treated differently if the machine stops due to an alarm during operation, and should not be run blindly to avoid damage to the machine;

4. For newly executed procedures, the first workpiece must be checked according to the drawings to avoid batch errors;

5. In the process of bending, it is necessary to stop the machine in time to check the abnormal situation of the mold;

6. Check whether the actual X-axis position is consistent with the measured value. If there is any deviation, adjust it in time.

2, stroke adjustment, use must pay attention to adjust the stroke, must be tested before bending. Its upper die down to the bottom must ensure that there is a plate thickness clearance. Otherwise it will cause damage to the mould machine. Stroke adjustment is also electric quick adjustment.

3, bending notch selection, generally choose the plate thickness of 8 times the width of the notch. For bending 4mm sheet metal, choose about 32 notches.

4, the rear stopper adjustment generally has electric quick adjustment and manual fine tuning, the method is the same as the shearing machine.

5, step on the foot switch to start bending, CNC bending machine mold and shearing machine is different, can be loosened at any time, loosen the foot will stop, continue to step down. Plastic CNC bending machine tooling, plastic folding machine, plastic board CNC bending machine mold, plastic plate bending plastic plate bending directly, without joining together, without slot, don't need a electrode, the Angle of the appearance it hold water, it will be hand soldered into a fully automatic machine operation, improve the quality, improve the work efficiency, reduce the labor cost, Greatly shorten the production cycle of products. Automatic plastic Angle folding machine belongs to electrical integration of automatic mechanical equipment.


According to the principle of plastic plate heating and melting and welding, it is suitable for all thermoplastic materials folding Angle. High speed, beautiful surface and high strength. Hydraulic plate shearing machine is divided into pendulum type and gate type. Swing activated carbon is circular motion, and the arc blade production is very difficult, generally with the blade to do pad iron compensation, so the gap is not accurate, cut out the sheet is not very ideal. Because it is an arc movement, the blade can not be made into a rectangle, but should be made into an acute Angle, so the stress of the blade is not ideal, blade damage is also more severe. Do pendulum shearing machine domestic representative for tianshui machine tool factory and punching shear machine tool factory. Brake type hydraulic plate shearing machine to overcome all the above problems. But at present domestic manufacturers can do the gate type plate shearing machine is not much. Relative to the shearing machine, CNC bending machine mold technical content is slightly higher.

At present domestic common G shape and F, F shape should be domestic traditional product, its use is built-in adjustable mechanical stop positioning, because it is built-in the partial load resistance is weak, so have the Yellowstone in the early days of CNC bending machine mold has a balance valve, but also because of the hydraulic, too multifarious, brings to the late maintenance and stability is very serious problem. The latter type is G type improved after F type, which adopts external sliding plate mechanical positioning. Compared with F type, it is simpler and more convenient for debugging. Even in the case of Angle difference on both sides, non-professionals can add gaskets to solve the problem.


Now there is a H type CNC bending machine mold, its structure is very different from the two before, it is a lever structure, generally used for large tonnage CNC bending machine mold, through the principle of lever amplification, the force amplification. At the same time, it adopts the position control with the combination of electrohydraulic and digital, so that it is particularly cost-effective in the same tonnage CNC bending machine mold. But there are not many manufacturers that can produce this kind of model in China. The main characteristics of CNC hydraulic plate CNC bending machine die bed are as follows: WC67K type CNC bending machine die, steel plate welding structure, vibration aging eliminate stress, the machine has a good rigidity and stability, the whole frame rigid, stable work, safe and reliable, easy to operate, through the CNC bending machine die CNC system and hydraulic system coordination control, to achieve the ideal bending effect.
