Friendly Operation Disc Type Stranding Equipment Pre Twist Conductor Making

1. Application: This machine is mainly used to produce large section and large length steel cored aluminum strand and aluminum alloy wire without untwisting; It can also be used for non untwisting twisting and pressing of copper round and aluminum sector wire cores.

2. Overview of equipment composition

The whole machine is driven by separate motors. Each section of the hinge and traction is driven by a separate motor, and the hinge is driven to rotate through a special gear box. The control of the whole machine adopts Siemens S7-200 series PLC to ensure synchronization accuracy. In actual production, the operator can set the process parameters such as the pitch of each section of the stranding body and the speed of the production line on the touch screen according to the cable specifications to be produced, and automatically calculate the speed of each transmission part and control the paying off tension through PLC when starting up, so as to ensure the synchronization of the whole machine and the accuracy of the stranding pitch, and realize the stepless speed regulation of the whole machine.

Using digital quantity to detect wire breakage can accurately judge the wire breakage signal of any coil in each section of the hinge, and display which section and coil is broken on the touch screen of the main console, so that the accuracy and accuracy of wire breakage detection can be significantly improved and the detection accuracy can be ensured.

Pneumatic proportional valve controller is used for the reel tension of each section of the winch to automatically calculate and track the reel diameter and adjust the reel tension to ensure the stability of the reel tension. The tension proportional coefficient can also be manually adjusted in the touch screen when starting up.

Siemens S7-200 series PLC and collective PROFINET fieldbus are used for unified control of the whole machine operation to coordinate the working state, operation and speed control of all parts of the whole machine. The operation touch screen adopts Siemens color man-machine interface to control the operation.

5. Main features:

• The whole machine is driven by motor, and each section of winch and traction are driven by a separate motor and driven by a special gear box
• Compared with the traditional frame winch driven by the ground shaft, the structure of the winch is simplified and the maintenance of the equipment is more convenient.
• Siemens S7-200 series PLC is used for the control of the whole machine. The production process parameters are set through the touch screen. Each section of the winch and traction are driven by an AC variable frequency motor. The motor driver is a frequency converter device. In order to ensure the transmission accuracy, the transmission motor adopts grating encoder feedback. The whole machine adopts bus communication to ensure the accuracy of signal transmission. During actual production, the user sets the process parameters such as the pitch of each section of the stranding body and the speed of the production line on the touch screen according to the required cable specifications, and determines the speed of each transmission part through PLC automatic calculation when starting up, so as to ensure the synchronization of the whole machine and the accuracy of the pitch of the stranding wire, and realize the stepless speed regulation of the whole machine. The electric control system has advanced technology, convenient operation and reliable operation.
• The digital quantity is used to detect the broken wire, which can accurately judge the broken wire signal of any disc in each section of the twisted body, and display which section and which disc is broken in the touch screen of the main console, which significantly improves the accuracy and accuracy of the broken wire detection and ensures the detection accuracy. Through the display in the touch screen, the operator can quickly solve the problem and start the next time.
• The reel tension of each section of the winch adopts a pneumatic proportional valve controller, which automatically calculates and tracks the reel diameter to adjust the reel tension, so as to ensure the stability of the reel tension. The tension proportional coefficient can also be manually adjusted in the touch screen during startup.
• For the hanging operation of each section of the winch, an AC motor is used to drive the winch to rotate through a high speed ratio reducer for slow positioning. The AC motor is driven by frequency converter, which is controlled by bus.
• The control power supply of the machine adopts UPS uninterruptible power supply to ensure that it will not lose control in case of power failure. All frequency converters are connected by common DC bus to realize load sharing. At the same time, traction flywheel is equipped to ensure that the cable will not be over twisted in case of power failure.
• The machine adopts imported Siemens S7-200 programmable controller and PROFINET field bus to command and coordinate the electrical working state of all parts of the machine, and uses frequency converter to control the starting and operation of AC motor. Siemens color touch screen is used to set and display various process parameters. The electric control system has advanced technology, convenient operation and reliable operation
