(9) The surface of the wire drawing reel is designed with R and graded inclination angle. The moderate R angle ensures that the steel wire required by the user has sufficient thrust, so that the steel wire moves up smoothly after drawing. The graded inclination angle ensures that the steel wire is neatly arranged during cold shrinkage. , Continuous heat exchange with the reel; the base material of the reel is 45#, heat treated after rough machining, the hardness of the base is 48°, and then the surface of the reel is sprayed with tungsten carbide, the hardness is 58°--- 62°, the reel after grinding The surface finish is less than or equal to 0.02mm, and the smooth surface ensures that the steel wire is not scratched. The water cooling system of the reel has a national patent: the inside of the reel adopts a self-descaling system, the cooling water and the inner wall of the reel maintain a 5mm gap, and the cooling water is evenly around the inner wall of the reel For heat exchange, the efficiency of this structure is proved to be more than 80%. The waterway system is free of repair after more than 10 years of use. It is the best technical equipment for high-efficiency drawing of low-carbon steel wire. The outdoor circulating cooling pool is made by the user. Recommended pool size: 3 meters long × width 2 meters × depth 2 meters
(10) The spindle bearing adopts Japanese NTN
(11) The high-speed rotating pulleys and reels on the wire drawing machine are dynamically balanced and calibrated in accordance with the national standard. There is no vibration during high-speed operation. There is no need to require ground level during installation. As long as ordinary iron blocks are placed in the gap during installation and then fixed with ordinary expansion bolts. , No need to embed anchor bolts
(12) The unique rotating mold box uses a low-speed high-torque motor and a reducer to drive the drawing die to rotate during work. The lubricating powder attached to the surface of the steel wire is forced into the die in a spiral shape, so that a lubricating film with a thickness of 0.04mm is formed on the surface of the steel wire. , To ensure the amount of lubrication required for the multi-pass drawing of the steel wire. According to the actual production, the mold can extend the service life by more than 2 times; as we all know, the raw material of the steel wire is elliptical and has a certain degree of flash (or When these flashes enter the mold, they cause partial overpressure on the mold. What's more, these flashes fall off at the mold opening, blocking the lubricating powder from entering the mold, greatly shortening the service life of the mold, and rotating the mold. The mold bears these irregular forces evenly, and the rotating mold port discharges some of the flaked flash, which ensures the smooth passage of the lubricating powder into the mold. The rotating mold box also has the function of stirring the lubricating powder. The user only needs to add the lubricating powder without manual stirring, which reduces the labor intensity of the workers and improves the safety of the workers. The roundness of the steel wire drawn by the rotating mold is 0.001mm~ Between 0.003mm, we recommend the outer dimension of low-carbon steel wire mold Φ40mm※25mm
(13) Before the wire drawing machine was released, the noise, water system, gas system, oil mist separator equipped with observation window and gas system were tested. The working hydraulic valve, water flow, air pressure and flow control valve are all obvious, and the user uses easy and convenient
(14) AC variable frequency linear wire drawing machine electrical control system: This system adopts the frequency converter to adjust the speed and the PLC program controller to realize the digital automatic control. Each head on the machine has a start, stop, jog button, tension and air pressure adjustment; emergency stop pull rope in front of the machine. There are speed display and speed regulation, weight or length setting or release on the touch screen. Running machine number, running current (observing the size of the current can clearly know the wear status of the mold), running frequency (observing the size of the frequency can know the actual maximum working speed), and the power of each head. Inputting the actual running mold on the touch screen can intuitively display the reduction rate of each pass to avoid unreasonable drawing. By observing the fluctuation of the current, you can find and adjust the damaged mold to avoid production waste! The system also has some special functions: thread threading, continuous thread function, automatic emergency stop function when high-speed running interrupts the thread, and remote monitoring and repair function.
