Press Brake
Press brake is are mainly used in the sheet metal industry, such as bending, forming of automobiles, doors and windows, steel structures, etc. And V-grooving and other fields for thin metal sheets.
CNC press brake is of BOSCH-REXROTH nofeedback electric hydraulic servo control on ram movement synchronously .
It adopt the overall welded and processed structure, more durable Closed loop control mode composed of electric-hydraulic servo valve and measure ruler, ensure the highest controlling precision, bending accuracy and repositioning .The accuracy are also reach the highest level The backgauge mechanism can control several backgauge axes.Integrated hydraulics system decreases the pipe connections, oil leakage, and increases the stability and overall beautifies.Hydraulic compensation mechanism helps to prevent the deformed slider from attesting the quality of the workpiece, and the compensation mechanism is adjusted automatically by the CNC controller which is convenient and accuracy.
High precision grating feet installed on C type rack, overcome the fuselage bending deformation folded in half the influence of accuracy The control device of back gauge, not only simple but also stable and reliable has elegant appearance.
The angle of the hydraulic CNC bending machine is beautiful and watertight, and the processing speed is fast. The surface of the folding angle is beautiful and the strength is high. The numerical control machine greatly improves the quality and labor efficiency, reduces the labor cost and shortens the production cycle of the product.
Press brakes can be used for many different farming jobs with the right die design. Types of dies include:
V-dies—the most common type of die. The bottom dies can be made with different-sized die openings to handle a variety of materials and bend angles.
Rotary bending dies—a cylindrical shape with an 88-degree V-notch cut along its axis is seated in the “saddle” of the punch. The die is an anvil over which the rocker bends the sheet.
90 degree dies—largely used for bottoming operations. The die opening dimension depends on material thickness.
Acute angle (air-bending) dies—used in air bending, these can actually be used to produce acute, 90 degree, and obtuse angles by varying how deeply the punch enters the die by adjusting the ram.
Gooseneck (return-flanging) dies—The punch is designed to allow for clearance of already formed flanges.
Offset dies—a combination punch and die set that bends two angles in one stroke to produce a Z shape.
Hemming dies—two-stage dies combining an acute angle die with a flattening tool.
Seaming dies—there are a number of ways to build dies to produce seams in sheets and tubes.
