V. Introduction to mechanical equipment
The unit consists of unwinding machine, unwinding looper, horizontal pinch feeding roller, cleaning device, straightening device, traction mechanism, pre-bending device, receiving device and electronic control system.
1. Power unwinding machine: It consists of motor, reducer, frame, tray and brake device. The high-material frame of the Φ3050X800mm (1500 mm) disc puller is allowed to be placed on the tray, and the coiled tubing is used as the raw material of the wound pipe.
Unwinding motor: AC change Y112M-4 5.5KW 1440r/min.
2. Unwinding looper: consisting of bracket, support arm, idler, vertical roller, swing arm and other components. It supports the pipe to a certain height through the roller, guides the pipe by the vertical roller, and smoothly introduces the horizontal pinch from the tray. Pair of rolls. The rotation speed of the unwinding disc is the swing angle of the swing arm, and the swing ratio is amplified by a pair of gears, input into the computer system, the frequency is adjusted, and the rotational speed of the turntable is controlled to achieve the synchronization of the whole machine speed. The torsion spring is used to control the swing angle and adjust the torsion spring force according to the diameter of the pipe.
3. Horizontal pinch-to-roller: Two pairs of horizontal pinch rolls are used to feed the pipe into the cleaning device, and both pairs of pinch rolls are driven passively.
4. Cleaning device: mainly for cleaning the surface of the tube blank and dust, the cleaning medium is the surface cleaning agent of the copper tube , and is directly supplied by the cleaning pump station. The entire cleaning process is fully enclosed.
5. Straightening device: consists of a vertical straightener and a horizontal straightener, which work together to straighten the copper tube . The vertical and horizontal straightening machines are all nine-roller active straightening, four-roller stipulation, and the five-roller can be adjusted by hand wheel alone.
6. Traction mechanism: transmission through the crawler type.
7. Receiving device: consists of turning mechanism, beam, material frame and so on. After the tube blank is sawn off, the rear feed roller accelerates the tube blank to the turning mechanism, the length of the discharge roller path is greater than 4 m, and then the finished tube is turned into the adjacent material frame.
8. Electronic control system: It adopts PLC centralized control, adopts AC frequency conversion technology to control the start, stop, acceleration and deceleration of discharge and feeding motor, AC servo system and relay control system control. The electronic control system consists of an electric control cabinet, an operation console and an operation box.
9. Hydraulic system: Mainly used for lifting cylinders of the winding table.
10. The water cooling section: passing through the cooling spray cooling and immersion cooling section two brass is cooled to room temperature, the brass can be controlled by adjusting the temperature of the cooling tank into the water, the optimal temperature is 60 ~ 80 ℃ .
11. The direction of the pay-off reel is: clockwise to take the line, the take-up reel takes the line direction: counterclockwise to take the line.
Copper tube induction heating continuous annealing production line This control system has what are the characteristics:

Found ② The control voltage calculating frequency power supply module. The method is simple and reliable, and is not subject to temperature measurement devices.
Measure the impact of the power system operating state. The precise power control model guarantees the control accuracy of the annealing furnace.
3 copper tube micro tension control function. The copper tube is automatically built during the heating process, so that the copper tube is annealed
Not stretched or shrunk in the state.
4 receiving and discharging speed compensation function. Use the loop detection and collection and discharge speed compensation calculation to ensure the receipt of the basket,
The discharge speed follows the linear velocity of the annealed copper tube , and the discharge is stable and the material is balanced .
