Auxiliary mechanism of multifunctional high-speed water tank wire drawing machine
1.4.1 Drafting mechanism
The traditional water tank wire drawing machine, before drawing, usually needs to pass through the die after rolling. These need to be done manually. The steel wire needs to be passed through the die several times, and a tipping machine is required. , The pulling force of about 700N is required to pass the mold to Ф1.5mm, and the pulling force of about 430N is required to pass the mold from Ф1.1mm to Ф1.0mm. , The labor intensity is relatively large, so a motorized wire drawing mechanism is designed. When the steel wire passes through the mold, it is completed by a special mechanism. In the actual use process, the labor intensity of workers is greatly reduced, and the time for the whole machine to pass through the mold is doubled, and the effect is remarkable.
1.4.2 Other institutions
For the flip-type water tank wire drawing machine, it can be equipped with an automatic flip mechanism instead of manual operation; when the finished die is drawn, it is equipped with a double-die mechanism to improve the surface quality of the finished steel wire; The wire diameter of the steel wire in the production process is detected in time.
2 Electrical control system
The wire drawing and take-up of the whole machine adopts full AC frequency conversion control system, and the wiring adopts servo control system. The hardware is equipped with frequency converter, programmable logic controller (PLC), touch mode screen (HMI) and electronic counting switch, PLC high-speed pulse capture, The meter counting accuracy is controlled within 0.1%. A communication interface is installed in each electronic control system, and the PLC Ethernet module of each device is formed into an industrial Ethernet through the PROFIBUS field bus control system. The state of each wire drawing machine on the current site is monitored by computer, and all process parameters are stored in the computer. Through this system, multi-machine integration and intelligent management can be realized.
During the drawing process of the steel wire, the temperature of the emulsion should usually be lower than 50 ℃, so the emulsion in the water tank is monitored by the temperature sensor, and the electrical signal is transmitted to the PLC, so as to control the size of the flow regulating mechanism. At a certain set value, the flow can be automatically compensated to realize the automatic temperature control of the emulsion.
