If you heard the Press Brake Machine<\/a> first time, maybe you can not connect it with the sheet bending machine.<\/p>\n\n\n\n

Now lets us learn the development of the sheet bending machine<\/p>\n\n\n\n

What is the definition of sheet bending ?<\/h4>\n\n\n\n

Under the pressure of the upper or lower die of the bending machine, the sheet metal and the inner surface of the V-groove of the lower die <\/p>\n\n\n\n

gradually with the pressure of the upper die or the lower die to make the upper die and the plate three points Close to full contact, to make a V-shaped bend completed at this time, which commonly known as bending.<\/p>\n\n\n\n

The development of bending machines<\/a><\/h4>\n\n\n\n

Sheet bending machines range from manual folding machines to electric folding machines at the beginning. <\/p>\n\n\n\n

As people’s requirements for bending sheets are getting higher and higher, the thickness and length of the sheets are getting larger and larger, so hydraulic bending machines have appeared. <\/p>\n\n\n\n

The bending force of the bending machine far exceeds that of the folding machine, which satisfies the bending of large equipment such as aerospace and ships. <\/p>\n\n\n\n

Up to now, some large factories have higher requirements for bending accuracy and bending automation, so fully automatic CNC bending machines have appeared.<\/p>\n\n\n\n

Manual folding machine<\/h4>\n\n\n\n

This machine tool adopts the lower knife to fix, the upper knife to press tightly, and then use the principle of turning over the folding plate for folding. <\/p>\n\n\n\n

This machine tool widely use for bending and flange steel plates, non-ferrous metal plates and stainless steel plates.<\/p>\n\n\n\n

It widely favor by many customers at home and abroad for its lightness, <\/p>\n\n\n\n

energy saving, high work efficiency, multiple production, wide application range, and easy handling.<\/p>\n\n\n\n

Electric folding machine<\/h4>\n\n\n\n

This machine is a general-purpose thin plate folding machine, which can bend into a variety of different cross-sectional shapes after one or more folding steps and at the same time change the cutter as needed. <\/p>\n\n\n\n

It widely use in the manufacturing of automobiles, ships, electrical appliances, kitchenware and air-conditioning and ventilation equipment.<\/p>\n\n\n\n

The body is all welded with high-quality steel plates. Compact structure, high strength, sturdy and durable, beautiful and generous, safe and reliable, simple operation; convenient adjustment, maintenance and maintenance.<\/p>\n\n\n\n

Hydraulic NC bending machine<\/h4>\n\n\n\n

The machine adopts an all-steel welded structure, which has sufficient strength and rigidity, and through aging treatment, ensures the overall accuracy of the machine tool for long-term use.<\/p>\n\n\n\n

It adopts a large floor boring and milling machine, and uses one-time processing method for precision processing to ensure processing accuracy.<\/p>\n\n\n\n

Working principle<\/h5>\n\n\n\n

Two oil cylinders use to realize the up and down movement of the slider, thereby providing the bending force required for bending the sheet.<\/p>\n\n\n\n

The mold of the bending machine can replace to meet the needs of various workpieces.<\/p>\n\n\n\n

Electro-hydraulic synchronous CNC press brake<\/h4>\n\n\n\n

The machine adopts an all-steel integral welded structure, and eliminates internal stress through normalizing and high-frequency vibration, <\/p>\n\n\n\n

ensuring the overall accuracy of the machine tool, with excellent rigidity, and excellent anti-torsion and anti-tilting capabilities. <\/p>\n\n\n\n

The thickened worktable and the thickened sliding block make the whole machine have high rigidity, so the sliding block and worktable deform very little when bending, <\/p>\n\n\n\n

and the workpiece has excellent straightness and angular consistency.<\/p>\n\n\n\n

Features<\/h5>\n\n\n\n

1.The bending process which automatically calculated.<\/p>\n\n\n\n

2.The blanking length of the bending workpiece can be automatically calculated.<\/p>\n\n\n\n

3. The computer automatically calculates the current and target positions of each bending angle and each axis.<\/p>\n\n\n\n

4. The size of the bending pressure will also automatically calculate and adjust by the computer <\/p>\n\n\n\n

along with the length or thickness of the workpiece.<\/p>\n\n\n\n

5. According to the bending pressure automatically calculate and adjust by the computer, <\/p>\n\n\n\n

the deflection compensation of the working table automatically calculate and adjust, which is fast and accurate.<\/p>\n\n\n\n

As the requirements of the sheet bending machine and the development of the technology, <\/p>\n\n\n\n

the machine evolved from manual folding machine to electric folding machine , <\/p>\n\n\n\n

and then become today widely using hydraulic press brake machine.<\/p>\n\n\n\n

No matter what it is , the press brake is the machine for bending sheet , just like the show in below video<\/p>\n\n\n\n
