Main advantage of rigid stranding machine

• The whole machine is driven by separate motors. Each section of the stranding body and traction is driven by a separate motor and driven by a special gear box.
• Compared with the traditional ground shaft driven frame winch machine, the twisting body rotates, which simplifies the structure and makes the maintenance of the equipment more convenient.
• The whole machine is controlled by Siemens S7-200 series PLC, and various production process parameters are set through the touch screen. Each stranding and traction section is driven by an AC variable frequency motor, and the motor driver is a frequency converter device. In order to ensure transmission accuracy, the transmission motor It adopts grating encoder feedback and the whole machine adopts bus communication method to ensure the accuracy of signal transmission. During actual production, the user sets the process parameters such as the pitch of each strand and the speed of the production line on the touch screen according to the specifications of the cables required to be produced. The PLC automatically calculates the speed of each transmission part when starting up the machine to ensure that the entire The synchronization of the machine and the accuracy of the stranding pitch are achieved, and the stepless speed regulation of the entire machine is achieved. The electronic control system has advanced technology, easy operation and reliable operation.
• The digital quantity is used to detect wire breakage, which can accurately determine the wire breakage signal of any disk in each section of the strand, and display which section and disk of the wire is broken on the touch screen of the main console, making the wire breakage detection more precise and accurate. Significantly improved, the detection accuracy is ensured. Through the display on the touch screen, the operator can quickly solve the problem and start the next startup.
• The reel tension of each section of the strand adopts a pneumatic proportional valve controller, which automatically calculates and tracks the reel diameter to adjust the reel tension to ensure the stability of the reel tension. The tension proportion coefficient can also be manually adjusted on the touch screen when starting up.
• For the loading operation of each section of the strand, an AC motor is used to drive the strand to rotate through a large speed reducer for slow positioning. The AC motor is driven by a Danfoss inverter, and the inverter is controlled by a bus.
• The control power supply of this machine adopts UPS uninterruptible power supply to ensure that it does not lose control when the power fails. All frequency converters are connected by a common DC bus to achieve load sharing. It is also equipped with a traction flywheel to ensure that the cable will not be over-twisted in the event of a power failure.
• The machine uses an imported Siemens S7-200 programmable controller and a collective Profinet field bus to uniformly command and coordinate the working status of all electrical parts of the machine, and uses a frequency converter to control the starting and operation of the AC motor. Siemens color touch screen is used to set and display various process parameters. The electronic control system is technologically advanced, easy to operate and reliable in operation.

5.2.4 Each section of the strand is driven by a separate AC motor through a special gearbox, and can rotate left and right. The gearbox has two high and low speed gears. The high gear is used during normal stranding, and the slow gear is used when changing the disc. The main motor drives the stranding body to rotate at a slow speed, and the position of the upper disc is automatically positioned using a handle switch.
5.2.5 Frame structure, the entire stranded body is double-supported by the front and rear support frames, and the middle is supported by a seamless steel pipe. The main steel plate connection surface of the frame is processed and welded with high strength. The overall frame after welding is annealed at high temperature in an annealing furnace. The deformation and stress caused by the welding of the steel plates are accelerated and aged. After 72 hours, it is naturally cooled to the natural state. temperature, effectively enhancing the strength of the entire frame. There is a machining allowance for the brake surface of the strand body and a margin for the top mounting hole. After all the holes are drilled and milled in the gantry machining center, they are then finished on a heavy-duty horizontal lathe. The bottom plate of the strand is made of welded rectangular tubes. Compared with the ordinary channel steel bottom plate, it effectively enhances the stability of the strand and is more suitable for high-speed rotation of the strand. Dynamic balancing test after assembly of the stranded body to ensure stable high-speed operation.
5.2.6 The single-line pay-off tension is electronically detected and electrically controlled, and adjusted by a pneumatic control proportional valve imported from Japan to achieve constant single-line pay-off tension from full to empty.
5.2.7 The wire reel adopts end-axis pneumatic clamping, and the cylinder clamps the wire reel from bottom to top to facilitate the up and down of the wire reel. After the wire reel is clamped, the pneumatic interlocking mechanical safety locking mechanism realizes linkage and stop retreat.
5.2.8 Using digital quantity to detect wire breakage can accurately determine the wire breakage signal of any disk in each section of the strand, and display which section or disk is broken on the touch screen of the main console. The parking length for wire breakage detection is 2M. Within (when the line speed is 20M/MIN), the accuracy and accuracy of wire break detection are significantly improved, ensuring detection accuracy.
5.2.9 The loading operation of each section of the stranding body adopts the slow speed gear on the gear box. The main motor drives the stranding body to rotate slowly for slow positioning. The proximity switch is used to detect the positioning pulse signal to ensure the loading of the stranding body. The location is accurate.
5.2.10 The surface of the tension plate is ground to ensure the stability and balance of the tension.

5.2.12 Each section of the strand is equipped with a hydraulic side lower loading device.
5.2.13 Each section of the stranded body is equipped with a set of single-wire preforming devices. The single-wire preforming device is used for stranding round single wires to ensure that the single wires are not loose after the conductor section is disconnected after stranding.
5.2.14 The single-section winching cage of this machine is equipped with a central wire protection tube.
5.2 Lower side loading device
5.3.1 Applicable cable reel PND630mm
5.3.2 This loading device is an automatic loading device at the bottom of the hydraulic drive side. It consists of an auxiliary mechanism for the upper and lower disks, a chassis, a flipping loading mechanism, a linear motion guide rail pair, and a hydraulic system.
5.3.3 When the overturning upper plate mechanism is in the horizontal position, the line reel is pushed into the fixed position from the upper plate turntable, the hydraulic drive system starts to work, and the piston rod of the winch-connected oil cylinder stretches out (the line disc bracket and the piston rod are winched. Continuous connection) drives the upper plate device to perform a flipping motion with the fixed axis as the base point. When flipped to the set angle, the bottom surface of the guide rail hits the limit device on the bottom plate of the winch and stops flipping. At this time, the piston rod continues to work, and the drive wire reel bracket makes a linear motion along the guide rail to the side upper disc to send the reel under the action of the linear motion guide rail pair. When the wire reel reaches the strand clamping position, the cylinder piston rod stops extending under the action of the limit switch, and the strand clamping device works to clamp the wire reel.
5.3.4 After the wire reel is installed, the oil cylinder piston retracts, and the wire reel bracket moves linearly downward and sideways along the guide rail. When the movement reaches the limit at the bottom of the guide rail, the wire reel bracket stops sliding, and the wire reel bracket and both sides The guide rails are turned together along the fixed axis until the cylinder piston retreats to the bottom and the wire reel bracket returns to the horizontal position.
