1. double station cantilever payoffs: three groups of wire guide wheel, the rotating arm can be 900 rotation, two rolls of blank line can be placed under the rotating arm.

2. Cable host:

2.1 Pull wire drum axis tilt 2.50, arranged in straight line.

2.2 There is a 2.50 tilt between the drum wheels. The incoming wire and outgoing wire should be staggered to avoid the wire chafing each other, so as to improve the quality of the drawing wire.

2.3 The wire drum wheel is driven by the carburized and grinded cylindrical helical gear, which has large transmission power, high efficiency and easy to replace.

2.4 Drawing liquid immersion cooling method. All drum wheels are immersed in the drawstring groove, and cooled outside the groove for liquid supply and recovery. The pull wire lubrication cycle in the groove is separated from the gear drive lubrication system, and the pull wire coolant is isolated from the drive oil.

2.5 The drum wheel and the drawing die are in a long tank filled with cooling lubricating fluid. The wetted drawing wire is provided with two quick discharge valves at the bottom of the tank. When the line breaks and other conditions need to be dealt with, the liquid can be quickly discharged by turning the valve handle.

2.6 The fixed speed wheel and line dividing wheel are inlaid steel wheel structure, and the drum ring is sprayed with carbide to improve the service life of the drum ring.

2.7 The 13th die base is designed as a rotating structure. When the wire is drawn, it slowly rotates at a constant speed of 31r/mim to improve the roundness of the finished wire and the service life of the wire drawing die.

2.8 Special tip: The maximum outside diameter of the drawing die of this machine is 40㎜, the thickness is 30㎜, the outgoing die must be a polycrystalline die; It is best to use polycrystalline die for other drawing die, improve the service life of die and quality of finished wire, reduce drawing force and reduce energy consumption.

3. Line storage rack

3.1 It consists of an upper floating regulating wheel and a lower fixed regulating wheel. Floating regulating wheel under the action of the cylinder, so that the wire around the regulating wheel to produce tension, adjust the cylinder pressure can control the tension size.

3.2 The upper floating regulating wheel floats up and down under the action of tension and drives the corresponding potentiometer to rotate to control the speed of wire drawing and keep the speed of wire drawing synchronized.

3.3 The conductor drives the encoder to rotate when the lower fixed regulating wheel rotates. The encoder signal is input to PLC to calculate the drawing length and drawing speed, which is used for wire receiving and fixed length changing disk.

4. double disc automatic winding machine

4.1 Full pneumatic loading and unloading disc, the cylinder pushes the inclined CAM, so that the four-hinged connecting rod mechanism moves up and down. When the spindle hole of the wire reel is at the center position, press the switch button, and the cylinder pushes the center to tighten the wire reel under the condition that the wire reel rotates slightly. The pneumatic locking pin is inserted into the central shaft sleeve to make the movable central positioning lock.

4.2 Wide speed regulating AC frequency conversion motor drives ball screw to drive the wiring rack to the rewiring. When the fixed-length signal reaches the start of the disk changing operation, the cables are shuttled in a small area near the hanging disk side to ensure that the length of the aluminum cables on each disk is the same.

4.3 Two 30KW DC motors are used to drive the two hanging coils and rotate at the same time when changing the coils. The linear speeds are consistent under the control of PLC program to ensure the stable tension of the storage wires without impact when changing the coils.
