wire in the reciprocating operation wire pole

EDM taper cutting of


Even lead to broken wire, which is its shortcoming 2. Torque motor tension wire agencies in the reservoir behind the installation of a tube slide,ralph lauren outlet, the slide after a fixed torque motor, the torque motor to maintain a certain torque, tighten the slider, the slider on the guide wheel tension wire pole to get some sheets clamping force. Such institutions can easily adjust the tension of; slide travel more, and can compensate for taper cutting the length of wire needed most. But the structure is more complex, high cost,fitch abercrombie, the same can not prevent the very wire for the vibration and to maintain a constant tension. 3. Magnetic clutch tension body theory and the advantages and disadvantages of such institutions, both institutions with the same torque motor tension, but the clutch costs are slightly lower. Tension of the above three institutions, there are some flaws, and to change in order to maintain constant tension to the wire when not caused by a very big vibration, this paper presents a new structure below. 4. Compensation wire torsion spring tension and a very busy agency agency management shown in Figure 8. It has four characteristics; 1. Roller, 2. The next slide; 3. Love on the block 4. Add the device: 5. Damper 6. Electrode frog 7. Guide wheels t8. Steel wall,abercrombie copenhagen, Figure 8 is up and down one arm while with the very tension on the wire, wire in the reciprocating operation wire pole, the force the same situation, so that the same surface quality, transportation back and forth will not have a significant difference between the machined surface when the wire. The second is the slider in the bottom two were the addition of two pulleys, makes a very different wire in the elastic case,ralph lauren danmark, · l4 · tension will not change. The t count u, v coordinates take the 35 mm stroke, torsion spring force changes only 9 grams or less, change the value of the tension is only 5 per thousand or less. The third is to eliminate the storm additional vibration damping device, effectively prevent a very large when the reverse wire vibration and risk of broken wires. The fourth is when the taper cutting,franklin and marshall uk, the freedom to compensate for a certain length of wire pole, to meet the needs of taper cutting. The advantages of such institutions, low cost, easy to adjust and tension remained unchanged,ralph lauren polo, while reducing the wire off the pole down and vibration, is an ideal tension and eliminate vibration institutions. If you replace the magnetic clutch torsion spring booster, tension can be completely constant. Fourth, the working fluid pressure light jet way domestic high speed wire EDM, the upper and lower nozzle from the workpiece, under the surface there is a considerable distance, merely an atmospheric pressure of working fluid around a very narrow kerf, so the working fluid over difficult to enter the cutting area, can not fully play the role of the working medium. Especially in the larger slope and thick-cut workpiece, the upper and lower nozzle of the spray direction is not in the same vertical direction, it is more difficult to make the working fluid into the cutting area. In order to smooth the working fluid into the cutting area to meet the needs of the taper cut, used in the design shown in Figure 5 the spray method, designed to be the next Sha mouth of f away from the workpiece surface under a fixed gap, and with the ram on the nozzle in the column on the move, cutting its travel range from the small thickness of the workpiece to a maximum thickness, which can be different according to the thickness of the workpiece, the same guarantees on the surface of the nozzle from the workpiece gap distance f the working fluid line of aircraft-5O2-Ⅱ cutting oil emulsion, and use a special pump, rated pressure of 8 ~ iOkg / cm. . Cutting,franklin and marshall sale, the working fluid damping gap by f, so that the working fluid pressure to maintain 2 ~ 5kg/cm. This can ensure that the working fluid is pushed into the work area, especially in the slope cutting, but also well into the Union so that the working fluid work area, to fully play the role of media,ed hardy sverige, cut into large taper to meet the needs. Fifth, other taper cut in order to meet the needs of machine tool motion accuracy, the overall stiffness, heat distortion, vibration isolation, etc., will resume according to the requirements of precision machine tool design. Currently, An ultrasonic plastic welding principles and characteristics of Figure 1 shows the principle of ultrasonic baking then it is the use of materials made of iron cobalt and nickel magnetostrictive vibration of the quartz sub-acid or lead titanate wrong electrostrictive vibrator, in its upload a fixed increase in rod, bar below the fixed rate of increase followed an increase in vibration tool can replace the head, the lower part of the tool head is then baked pieces. Thus, when connected to the ultrasonic generator, the ultrasonic vibration can be output to the frequency of 15-30kHz, amplitude of 4-5ftm about vibration, and then increase after a fixed rod and tool head can be changed by radiation amplified in the plastic welding surface can be get about 20 ~ 30ftm high frequency vibration. Thus, in the weld metal tool head end instantaneous maximum speed of up to 4m / s, much higher than the general ultrasonic impact force. This high-frequency plastic hammer effect delivered to the interface,ed hardy rea, where high stress occurs in the strong friction heat,abercrombie københavn, so the interface molten plastic under pressure, bonding the two parts firmly together. To achieve welding. Commonly used in plastic welding machine ultrasonic
