The wire drawing machine transforms straight wire rods rolled from the finishing mill into coils and feeds them onto an air-cooled roller conveyor. Its precision directly affects product quality. The wire drawing machine mainly consists of a transmission device, gearbox, hollow shaft, wire drawing disc, wire drawing tube, and bevel gears. Because the drive motor needs to be located on the side of the gearbox, and to reduce equipment placement in the workshop and facilitate personnel operation and inspection, the drive motors of adjacent production lines are placed on the left and right sides of the gearbox, respectively; these are referred to as the left line and right line.

[0031] Example: A universal left- and right-line coiling machine, mainly used in the coiling equipment of high-speed wire rod hot rolling production lines. The coiling machine transforms the straight rod rolled from the finishing mill into coils and feeds them onto the air-cooled roller conveyor. Its functional precision directly affects product quality. During the offline assembly process, such as... Figure 2-1 , 2-2The image shows the modified spinning machine and its lubrication pipeline. The spinning machine's lubrication supply system is connected via rigid pipes through a centralized lubrication station. Figure 3 The TOP section shown connects to the gearbox of the spinning machine. The pipeline is divided into three lines for oil supply. One line is achieved by changing the original two-way pipe fitting 1 to a three-way pipe fitting; and the oil supply pipe fitting 2 for the spinning machine input shaft is made using a stainless steel pipe of the same diameter as the original pipe. The oil supply line also supplies oil to the angular contact ball bearing inside the inlet bearing seat of the spinning box. Simultaneously, the gearbox housing is machined with... Figure 2-1 , 2-2 The oil passage 8 inside the housing (machined with reference to the original spinning machine input shaft oil passage) is fixed by pipe clamp 7 and threaded plug 3 is installed. When the input shaft is installed without using the spinning housing, the lubricating oil is sealed. One path is to change the meshing oil supply pipe between the two bevel gears to a gear meshing oil supply pipe 4 structure. When installing the oil nozzle (same as the original spinning machine), the position and angle are precisely adjusted to supply lubrication between the input shaft bevel gear and the hollow shaft bevel gear in the gearbox, so as to improve the amount of lubricating oil at the gear meshing point. When the gears rotate, the lubricating oil is carried up and splashed onto the meshing surface, reducing the friction and wear of the gear contact surface, lowering the working temperature, preventing corrosion, and removing wear particles at the same time. Another path is to use a stainless steel pipe of the same diameter as the original pipe to make the oil supply branch pipe for the cylindrical roller bearing of the hollow shaft of the spinning machine. Figure 3 The hollow shaft cylindrical roller bearing oil supply branch pipe 5 is shown, and an oil spray nozzle (same as the original spinning machine) is installed. Lubricating oil is precisely sprayed directly onto the rolling elements of the output shaft bearing of the hollow shaft through precise adjustment of the nozzle position and angle. An oil film is formed between the rolling elements and the raceway, reducing friction. The lubricating oil carries away the heat generated during bearing operation, avoiding direct metal-to-metal contact and reducing wear. Figure 4 As shown, due to the addition of an oil supply line in the gearbox, the machine was modified to be used as a universal spinning machine for both left and right lines. Therefore, the lubrication oil supply pressure of the spinning machine was increased to 3.0 bar to meet the bearing lubrication requirements under high-speed, heavy-load, and high-temperature conditions.

[0032] This type of universal left and right line spinning machine transforms equipment that was previously incompatible into a universal device. It allows for three-in-one operation with one standby and one maintenance, avoiding the increased costs associated with applying for a backup machine. Furthermore, through modifications to the oil supply pipeline and precise adjustment and installation of the nozzles, the online lifespan of the spinning equipment has been extended from 12 months to approximately 60 months. Compared to the original design, it features a simpler structure, easier and more secure installation, and convenient offline maintenance and reassembly. This also improves maintenance efficiency and reduces maintenance costs. The modification has yielded excellent results and significant economic benefits.
