The product should by means of a power cord connected to a socket-outlet with earthing connection. SAVE THESE INSTRUCTIONS APPLICATION: The CG2-11C type tube cutting machine is applicable for the seamless steel tube cutting and bevel cutting for such industries as petroleum, chemical, ship manufacture, electric power generation, machinery, building and installation. TECHNICAL PERFORMANCE AND CHARACTERISTIC CG2-11 type tube cutting machine possesses four permanent magnetic wheels, which can stick to the tube and go round it automatic cutting. Adapted Oxygen-Ethyne flame or Oxygen-Propane flame, it is suitable for various specs of seamless steel tube cutting and beveling provided the diameter is 108mm above. Due to the adsorption affinity of the magnetic wheels, this cutting machine can work in free direction such as flat, stand, across, face-up. The cutting and groove can be finished at the same time. This cutting machine can promise you higher efficient, better quality and less labor work. -3- MAIN TECHNICAL DATA 1. Dimension and weight: Dimension: 350(L)x270(W)x160(H) N.W: 14.8kgs 2. Cutting scope: Seamless steel tube dia.: 108mm above Tube wall thickness: 5-101.6mm 3. Cutting precision: Deviation: less than 0.5mm for one circle cutting on the159 - 425mm seamless steel tube Cutting and beveling surface roughness: 12.5 --- 6 4. Cutting speed: 50-762mm/min, step less adjustment by silicon controlled rectifier 5. Motor: ZYT70S-A24V Frequency: 68w rotate speed: 6000r/m 6. Control box: Power voltage: 110~120V 60Hz 7. Absorption affinity of magnetic wheel: more than 50 KGS 8. Driving momentum: less than 0.5mm when go down round the steel tube. -4- MAIN STRUCTURE 1. Driven Structure: Components: DC 70SZ08 power supply motor, 3 pairs of reduction gear and one pair of worm wheel. Please see the drawing below for the driven principle: 2. Tracking structure: Components: Magnetic roll wheel, axe, axe cover and magnetic steel. 3. Machine body: Box shape, made of aluminum alloy forged by ZL101. -5- 4. Cutting torch and tip: Use isobaric cutting torch and G021-3 model of cutting tip. The cutting torch is flexible through the adjustment of m=0.8 gear pair. The beveling angle can be adjusted according to different requirement. ELECTRICAL CONTROL SYSTEM INSTRUCTION The electrical control system is consisted of electrical box, body control panel and motor. In electrical box, there are power voltage transformer and circuit control board. Power switch, fuse and pilot lamp are equipped on the electrical box panel. On the body control panel, there are potentiometer for speed adjustment and switches for going back, ahead and stop. It adapts the silicon-controlled thyristor DC motor system to adjust speed. The thyristor is motivated through the signal superposition of AC and DC capacitance-Resistance and phase shifting and the DC signal will be changed to control the SCR angle of flow to realize the stepless speed adjustment of motor. For its detailed principle, please see the drawing below: -6- CUTTING TIP SPECS TABLE Cutting Oxygen pressure Ethyne pressure Cutting speed No. thickness (MPa) (MPa) (mm/min) (mm) 00 5-10 0 10-20 0.20-0.30 600-450 480-380 1 20-30 2 30-50 0.25-0.35 >0.03 400-320 350-280 3 50-70 4 70-90 5 90-120 0.3-0.4 0.4-0.5 >0.04 300-240 260-200 210-170 Note: The cutting tips, model from GO21 to GO2 3 will be supplied for one machine. Please purchase other types of cutting tip by yourself if needed. -7- OPERATION INSTRUCTION 1. Put the cutting machine on the steel tube carefully to avoid collision. Get the handle prior to cutting 2. If you have to change the direction during cutting, please stop the machine first, open the direction switch and then drive the machine. Please do not change the travel direction directly during its working to avoid the damage of electrical elements and machinery parts. 3. Before cutting, please adjust well the suitable oxygen pressure, ethyne pressure, cutting speed and beveling angle. Adjust the oxygen-ethyne to preheat the flame, move the cutting torch to align with the cutting mouth and open the oxygen-cutting valve for cutting when the steel tube is heated well. After finish cutting, please remember to shut the oxygen valve, ethyne valve and power. 4.The way to remove the torch cutter is shown in the following figure. Step 1: Place your hands on the handles which on both sides. Step 2: Press and hold the handle with one hand, and pull the handle on the other side with the other hand. -8- MAINTENANCE 1. Please remember to clean up rubbishes as iron scraps adhered to the roll wheels frequently 2. For the wind pipe surface, the travel place, the steel wire brush is suggested to be used for cleaning. Please don't do cutting on the steel tubes whose paints haven't been dry. Otherwise, the paints will stick on the roll wheel and the magnetic capacity will be reduced. 3. During the cutting, please avoid the oxygen-ethyne gas pipe and power wire to be hooked, which may cause the falling of cutting machine and its damage. After finishing use of cutting machine, please put it on the magnetic protection board at a dry place to avoid rust of roll wheel and magnetic phenomenon aroused. 4. The reduction structure shall be lubricated by supramoly and shall be replaced in every half a year. Please clean the new reduction device by carbon tetrachloride and lubricate it before the replacement. 5. If demagnetization occurs and absorption performance reduced on the magnetic wheels after certain period used, please unfix the magnetic wheel sets and magnetize them. 6. If the down momentum is too strong during work, please open the top left and right covers, adjust the left and right support bracket, endless screw and bevel wheel to ensure good cutting quality. -9- MAINTENANCE WARRANTY INSTRUCTION 1.
