hydraulic press brake,cnc press brake,cnc hydraulic press brake for sale

1. The application of the Hydraulic press brake machine

The folded sheet metal bending machine has high productivity and high working accuracy, using different shapes of up and down mould, can be bent into various shapes artifacts, slider stroke at a time can be to a bending forming of sheet metal, after a lot of bending can be achieved relatively complex shape workpiece, when equipped with the corresponding equipment, can also make a punch

2. The structure of the hydraulic press brake product shape

1).Using UG (fem) analysis method, the computer aided optimization design, beautiful appearance

2). The fuselage USES the steel plate welded structure, with sufficient strength and stiffness, hydraulic transmission to ensure work is not due to the thickness of the sheet metal change or die "V" shaped groove choose undeserved and cause serious overload accident, in addition the machine working smoothly, with convenient operation, low noise, safe and reliable, etc

3). The oil cylinder is equipped with mechanical stop, ensure the repositioning precision of the slide block to the top dead center, to ensure the consistency of the bending Angle when mass production

4). The whole framework USES the way play sand derusting, and spraying antirust paint

3. The performance characteristics

1). This machine adopts hydraulic electric control, sliding block stroke can be adjusted, and have some fixed, semi-automatic, automatic movements such as norm, using dynamic specification can easily test and adjustment

2). lift bending machine design, double oil cylinder work at the same time, balance, convenient operation, safety

3). The dead point have confirmed when rolling function, ensure that the workpiece precision

4). Under the condition of the relevant national standards, bending Angle precision of plus or minus *5 '. (refer to standard JB/T*********9)

5). A slow decline control function, the operator can better control the workpiece

4.Hydraulic system

1). Hydraulic system can realize the slider falling fast, slow down, bending work speed, quick return of slider stop in process of upward and downward movements

2). The axial plunger pump, oil pump adopt can withstand high pressure, low noise

3). Choose import company seal, sealed performance is good, reliable operation, long service life

4). The machine can work continuously under rated load, the hydraulic system without leakage and sustained stability, high precision

5.Electrical control system

1). The electrical components and materials in accordance with international standards, safe and reliable, long service life, strong anti-jamming capability

2). Comes with removable foot switch operation

3). The electrical components are famous brand quality products

4). The machine adopts frequency *0hz, **0V power supply three phase four wire system. Machine motor three-phase **0 v. Control transformer USES the two phase **0V. Control circuit used **0V, *9V control, electromagnetic valve, use 6.3 V control light is used

5). The motor main circuit has a short circuit, overload, open phase protection

6). Button on the action installed on machine tools, electrical switches, indicator lights, installed on the electric control box

7). Oil pump stop as well as the total machine tool , when the pump stop working, a complete set of machine stop working

8). The machine is equipped with corresponding inching control and stop

6.The slider synchronous control

Bending machine stroke of synchronization, using the mechanical hydraulic synchronous mechanism, simple structure, stable and reliable, with synchronous precision required for this machine, general need not often maintenance to maintain a long-term use

7.Stopper

Keep-off after adjustment by the 0.*5 KW motor drive, after geared by the screw drive, the press the regulation when pressing "+" and "-" to block plate the adjustment of the forward or backward, digital display size (location) in motor adjustment cannot achieve the required adjustment value, can be manually adjusted twisted round manual fine-tuning to ensure that the required adjustment value

8. Mould

1). The random standard mold one set up and down

2). The upper die with short over segmented mold, joining together the length should be, with high accuracy good interchangeability, easy tear open outfit. Connection part of the compensation mechanism, the sheet bending deflection to compensate for the workbench and the slide block, ensure a higher working precision.

3). The lower die is processed into different "V" shaped groove is convenient for the operator to choose, with lower die roll over institutions simply put the lifting chain on the slider lug and the lower die lug, loosen the top slider template rose can turn the lower die choose required to "V" shaped groove position
