Why need to buy one metal pressbrake machines?
From Mechanical metal brakes to torsion bar pressbrake, CNC pressbrakes to Hybrid pressbrakes for sheet metal bending jobs!
Obviously from the history of building pressbrakes, metal bending brakes are the common and basic fabricating solutions to suit industrial development. It was sometime after the industrial revolution began, sheet metal fabricating shops from all over the world realized that they needed a better way to bend thin sheet metal to various shapes. Basic machining principles were just beginning to be metal formed, as innovations were being introduced at a rapid pace.The first recognizable press brake (sometimes referred to as a “brake press”) was conceived by a company out of Kentucky in the late 1870’s. This crude machine was the first working production press brake as we know it today.
Fromt World War II, one mechanical type pressbrakes can reach the almost requirements of metal bending, using mechanical pry bar to drive top beam of pressbrake to down and up action to bending metal parts, while this pressbrake design cannot reach higher bending accuracy and nig noise always followed in shop, then one upgrated hydaulic pressbrakes with mechanical torsion bar design enter the sheet metal working machinery market, 2 hydraulic cylinders drive the top beam moving down and controlled by hydraulic valves of valves flow opening to reach bending pressure, mechanical torsion bar can be adjusted for parallel of 2 cylinders, that's traditional conventional pressbrakes, thus most of china pressbrakes still use this torsion bar design, but with NC pressbrakes controller plus motorized back gauge, pressbrake operators can set some bending program for X bending stroke and bending depth according to their experience..
And NC torsion bar can also adopt different NC controller to make bending angle program functions, operator just need to enter the target bending angle and Y axis will position automatically, that's comoputer calculating Y bending depth automatically.
But this did not stop the evolution of the modern press brakes, CNC pressbrakes using porprotional valves technology together with CNC controller, like DELEM, CYBELEC, ESA as well, Y1&Y2 have independent cylinders stroke controller, 2 linear scales mounted on both sides of pressbrake frames, it can read and monitoring real position of Ram moving, CNC pressbrake controller will calculate the correct position of Y1&Y2 moving values to finish bending cycle, cnc controller will give command to electro valves to get reasonable valves opening with required bending force, it's amazing development for sheet metal bending shops.
Then Eco friendly type drive pressbrakes design fresh our eyes, oil on demand design to reach higher bending accuracy and lower noise for your shop, no pedal down, pump won't work anymore.
Also the newest technology for pressbrakes is Hybrid pressbrakes, it combines hydraulic and electrical pressbakes with wonderful bending performance.
