CNC bending machine price  die in order to get long life, in the bending process should be as long as possible to adhere to continuous cutting. If the bending machine die enters and exits too frequently, the bending machine die life will be significantly shortened. This will increase thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more favorable to modern carbide bending machine dies than a large shake. The… Read More »CNC bending machine price: how to extend the life of the bending machine

The principle of choosing hydraulic pump of bending sheet metal Whether variable: radial piston pump, axial piston pump, single acting vane pump is variable pump. Bending machine working pressure: piston pump pressure 31.5mpa; Vane pump pressure 6.3MPa, high pressure can reach 21MPa; Gear pump pressure 2.5mpa, high pressure after up to 25MPa. Working environment: gear pump has the best anti-pollution ability. Noise index: low noise pump internal gear pump, double acting vane pump and screw pump, double acting vane pump… Read More »A machine capable of bending sheet metal

Many users do not know how to adjust the pressure after buying 30t hydraulic press brake machine, have called to consult. The following small series for you to introduce the pressure regulation method of 30t hydraulic press brake machine in detail: 1. Due to the thickness of the stainless steel plate and the different specifications of the V-hole on the upper die, it is necessary to adjust the distance between the stroke of the slider according to the development to… Read More »Do you know the pressure regulation method of 30t hydraulic press brake machine?

Safety operation rules for hydraulic pendulum shears First, carefully implement the relevant provisions of the "General operation Rules for forging and pressing Equipment". Ii. The following supplementary provisions shall be earnestly implemented: 1. Before the short running test run, manual steering should be used for a working stroke, and the equipment can be started only after the confirmation of normal operation. 2, hydraulic equipment, check the oil storage tank should be sufficient. After starting the oil pump, check whether the… Read More »Safety operation rules for hydraulic pendulum shears

How to use the Hydraulic Press Brake Machine to fold the arc You can bend it slightly so that you can create an arc. Here are the steps: 1, as shown in the red circle, put the place where you want to fold the arc under the bending machine. 2. Press the switch and press the bending machine. 3. As shown in the red circle, after the iron sheet is pressed by the bending machine, the hand only needs to… Read More »How to use the Hydraulic Press Brake Machine to fold the arc

Plate thickness 2mm bending Angle 120 degrees bending external radius 30 neutral layer radius 29, arc bending we calculate the arc length of the neutral layer. Therefore, the bending knife number and bending Angle of each knife are calculated according to the arc length of the neutral layer. The distance between the neutral layer and the edge is half of the plate thickness. How many arc-bending knives should be folded in the figure above, and what is the bending Angle… Read More »How to calculate the large arc bending Angle of CNC bending machine?
