3, test operation notes
3.1 after turning on the main motor power, adjust the speed control knob on the console to make the motor slowly accelerate from static. when the machine stops, the motor will slowly decelerate until it stops completely, then the brake will work, so as to ensure the drawing reel is safe and stable.
3.2 check the 'emergency stop' function of the console and reel unit. during operation, if the safety switch is operated, the machine should be mechanically braked quickly. this type of inspection is extremely important to avoid personal accidents and damage to parts in a critical situation.
3.3 in order to make the machine stop in an emergency when the line is disconnected, a disconnected parking function is provided on the machine.
3.4 functional check of the control system after the test is completed, the speed of the motor driving the reels shall be tested. the speed shall be the same as the rated speed of the motor. usually, the non-contact hand-held digital tachometer is used, with the help of the reflective marking on the motor pulley. to measure the motor speed, if the speed needs to be adjusted, adjust the inverter to complete. be absolutely careful when making adjustments! do not allow the motor speed to exceed the maximum allowable speed of the motor. the speed of each motor should be increased or decreased synchronously with the adjustment on the console. the speed display reading on the console depends on the speed of the last reel of the wire drawing machine.
3.5 after completing the above work, it is also checked whether the speed of each reel is the same as the actual speed. at this time, a non-contact hand-held digital tachometer can be used to measure the rotational speed of the reel by means of a reflective mark on the reel.
3.6 the wire drawing machine is designed with the reliability of all emergency switches in mind. in order to minimize the load caused by vibration, it is recommended to use the emergency switch only in a real emergency.
3.7 no-load test run first, let the machine run for 1 hour at the maximum speed of 1/4 speed, then check the temperature rise of all bearings. if the temperature rise is not higher than 30 °c, then increase the speed to 50% to make the machine run. 1 hour, check the water supply port seal and heat again. during the test run, if there is no abnormality, you can consider the no-load test to find out whether there is leakage and test temperature rise.
it is important to note that when the machine is first put into production, do not work under “full load” conditions. should be worn and maintained in front.
seven, running-in period and maintenance
the wire drawing machine must have been subjected to 6-8 hours of no-load cold towing. the load is run-in and the running-in is carried out in three stages:
the first stage: 30% of the load (30% speed) runs for 24 hours, no abnormalities occur, no excessive temperature rise.
the second stage: 40% of the load (fifty percent) is forty-eight hours of operation, no abnormalities occur, no excessive temperature rise and oil leakage.
the third stage: 70% of the load (70% speed) runs for 72 hours, no abnormalities occur, no high temperature rise and oil leakage.
after three stages of running-in, the grease (molybdenum disulfide grease) should be injected more thoroughly, and the machine should be fully inspected and put into full load operation.
eight, use and maintenance
1, the operation of the machine
1.1, threading operation
1.1.1, according to the conventional method, firstly, the thread is tipped, guided through a mold box filled with lubricant, into the first drawing die, after passing through the die, the wire is clamped by a wire cutter, and then hang the other end of the wire cutter in the hanging mouth of the upper part of the reel, jog the reel, and let the wire accumulate a certain number of turns on the working face of the reel, then loosen the wire drawing pliers, ready to enter the second drawing die, and put the wire material on. the second drawing die method is basically the same as the above, except that the foot rolls are used to jog the respective reels so that the wire material is tensioned between the reels, and then the left-hand drawing reel is slowed by the foot switch. the positive rotation causes the wire to accumulate the corresponding number of turns on the working face of the reel. so the analogy is completed and all threaded to the head.
1.1.2, high-speed copper plating part of the threading method, using the reverse wear method, is to go back from the dryer part, through the hot water wash each air nozzle - water washing - neutralization tank - water washing - copper coating tank (in plating the copper trough is reciprocally wound on the wire reel for 3.5 turns, then washing through the acid tank, reciprocated 4.5 times in the electrolytic cell, pulled out to the washing machine, and reciprocated 5 times in the washing machine to connect with the end line of the drawing machine. finally, the wire is drawed to the spool of the spool and the spool is connected to prepare for booting.
1.2.3, the wire is penetrated at a slow speed, and the threading speed of the reel controlled by the foot switch should be adjusted to the appropriate condition when the machine is installed. all the "input/cut" of the reel should be placed in the input position, and each pump and air switch should be linked to the linkage state. adjust the machine to the required speed on the console. normally, the speed change caused by the wire drawing wear can be automatically compensated.
1.2.4 when the equipment is working, pay attention to whether the lubricating powder of the wire is sufficient, whether the washing machine and the pickling electrolysis are cleaned, check whether the welding wire in the acid tank and the copper coating tank are below the liquid surface, and whether the wire is in the middle of each wind nozzle. pass, avoid scratching the wire, pay attention to adjust the position of the cable, ensure that the wire on the spool is flat, check the ph value of the liquid in the neutral tank is between 9 and 11.
1.2.5 the acid wheel and the pp wheel in the copper coating tank are replaced every 8 hours. the replaced wheel is cleaned and grooved, and the pp electrode is repaired and re-made for further use.
1.2.6. it must be emphasized that the protective cover must be locked during work to prevent injury when the wire is broken.
1.2.7. adjust the working speed. after starting the machine, pay attention to whether the machine is running abnormally. if there is any emergency stop, no work will be done.
note: do not put the hand on the fixed wire drawing pliers when threading. after the wire cutter is removed from the reel, put it in a safe place.
