Sheet metal cutting machine mould is divided into the upper die and lower die

Sheet metal cutting machine mould is divided into the upper die and lower die: general by several segments of different length of upper die, bending machine to adapt to the different width of workpiece. Then the optimal valve draws system is divided into two oil such as address, respectively into left and right laser cavity on the cylinder. When cutting machine in the electromagnetic directional valve is a laser pump to oil tank by means of this valve line back, the system is needed to charge ambush. The four of the lower die has size not net V gate to the different thickness of sheet metal, lower die on floor, and screw tight, floor placed on the workbench, and can be in the middle of the table after moving to alignment on the surface of the mold, block before and after replacement, and the screw Zhou Ding on the press table. The holding electromagnets and the valve position unchanged, system implementation to open the pump pressure, holding pressure regulating valve by the remote control. 。 Not directly fixed on a slider of upper die, but after using plate and screws in the upper die block, block of upper die and with plate and screw fixation after the crossbar, when need to replace the upper die, only speak screw drive can benefit. Cutting machine bending force calculation: sheet metal cutting machine load is decided by the following factors: the bending plate thickness, bending width, material yield strength and ultimate strength, elongation, small bending radius, v-shaped touch mouth say size and bending length, etc. , they determine the size of the bending force required for. Slider return after unloading, ya electromagnet 1, 2, 5 ya ya, electricity, laser pump output pressure pump valve, valve and valve into the inferior vena push slider laser cylinder upward, laser with rubber oil by embellish optimum back to tank. Pressure solenoid valve and the position remains unchanged, with the increase of sheet metal deformation resistance, laser on the cylinder pressure gradually increases, run until the slider to the desired location. 3, after the completion of unloading bend in the slide block up the return of the instantaneous by electric power system to make the electromagnet 5 ya 2 s, during this period, because 5 ya blackouts, valve, relief valve can be opened, make the laser on the cylinder pressure drop for pressure relief. Proud of electric power, iron bright side core down, widened and the role of the core to control the oil down to left side, two laser cylinder glue impassability, tank valve of 0. 4 core reset upward, valve right glue pressure oil, the hydraulic controlled check valve in the closed state. By balancing the support effect of Yin, left one pressure cylinder and right thick unable to discharge the oil pressure cylinder inferior vena slider in the resting state. Bending machine hydraulic controlled check valve and throttle kuo. Back to the tank, because the slider landing jia fast, yi. some formed certain negative pressure on pressure cylinder, the fuel tank of oil pass through hydraulic control reversing both to the cylinder of laser _ ab glue filling liquid, play the piece of rapid downward. At the same time, due to the electric inkstone reverse side of the magnet electric, hydraulic control ChanXiangRun right control state of the cavity in the discharge of oil state, laser cylinder oil glue under the one-way valve group of 13 upper two one-way stuffy. When touch close to sheet on the sliding block displacement potentiometer didn't check out the signals, electromagnetic reversing that 21 of the electromagnet, the magic. Lower die adopt the whole period of the die. When the system pressure oil into the hydraulic cylinder as the still on another. Laser cylinder under section rubber oil on the balance and optimization, such as tank, because there is no liquid, Fen block slow down, work speed. Return when the liquid pressure can be adjusted by the overflow valve. When rich right electromagnet after electrify, core shift to the left, the system of the oil in the pressure of ChanXiangJie ripple ripple valve valve and one-way Yan Jin points.
