At the beginning of dyeing machine development, the winding machine was an extremely simple mechanical transmission equipment. It relied on manpower to turn the crank to drive the winding shaft through gear transmission. This method was relatively backward, and the winding quality was determined by the operator's winding experience and skills; later development It is a winding machine with a motor as a power device, which greatly improves the work efficiency and makes the winding of thick enameled wire easier. The production of modern large motors and ultra-high voltage transformers is inseparable from thick wire winding machines. In recent years, the country has advocated low-carbon, energy-saving and environmental protection, especially for large-scale wind power projects in Northwest China.

The demand is driving the technological development of thick wire winding machines.The technical development of thick wire winding machines has also experienced several generations of model updates before modern CNC winding machines can be automated, efficient, and productive. Most of the first-generation thick wire diameter winding machines are reformed from large lathes. The motor drives a multi-stage gear reducer so that the torque of the main shaft can meet the winding requirements of thick wire diameters. The number of turns is realized after the main shaft is equipped with a counting device. Display function. This generation of models only meets the simple winding requirements of thick-diameter coils. Most of the functions that need to be realized are completed by the operator; the second-generation thick-diameter coil has a higher.


The machine body structure no longer uses the body of the lathe, and is developed by the winding machine manufacturer. The mechanical structure is also different according to the application. The transformer winding machine requires a larger The width of the winding machine meets the winding requirements. The motor winding machine needs a larger rotation diameter to meet the winding requirements. This generation of winding machines has functions such as preset turns, automatic winding, winding tension adjustment, etc., most of the current Manufacturers use this generation of models; the third generation of thick wire diameter winding machine uses a more technologically-content spindle motor, and also has a higher degree of automation.


The spindle motor uses a high-precision servo motor and electric integrated The reducer achieves high-precision power transmission. The winding motor also uses a servo motor to achieve high-precision and precise winding. The position of the thimble is generally realized by an electric position. This generation of models is the current winding machine manufacturer's Mainstream products, suitable for occasions that require extremely high winding precision. With the changes in winding requirements, the functional structure and development of winding machines, the technology of winding machines will also develop in the direction of higher automation, more efficiency and high production. Figure 1. 1 shows the development history of the winding machine. From left to right, there are manual manual winding machines, manual semi-automatic winding machines and fully automatic winding machines.
