Recent Progress in Manufacturing Technology of Medicine Core Welding Wire by Turntable Method
Welding technology is one of the key parts in manufacturing technology. The improvement of welding technology can not only improve the working efficiency and reduce the cost, but also guarantee the quality of the product. Therefore, the development of welding technology is of great significance for the industry. Recently, the manufacturing technology of medicine core welding wire by turntable method has made great progress in many aspects. This paper briefly introduces the research progress of this technology in recent years.
The basic principle of the medical core welding wire manufacturing technology by turntable method is to use a turntable made of steel wire to guide and drive the core wire through the welding area, and then concentrate the welding current of multiple welding electrodes on the core wire to form multiple welding spots in a circular shape. This process not only requires the high precision of the turntable, but also requires the manufacturing accuracy of the welding current and welding spots, which is the key factor that determines the quality of the welding wire.
Recently, a kind of new welding current forming technology has made great progress. This technology uses a numerical controlled stepping motor with an individual load resistor for each welding electrode to ensure the accuracy of stably regulating the welding current of each welding electrode. With the help of programmable automatic device, the welding current distribution is also greatly improved. Moreover, in order to guarantee the welding accuracy of the welding spots on the welding wire, a rotating accelerator is added to the steel turntable to further improve the control accuracy of the welding current intensity.
In addition, the diameter of welding wire is also an important factor affecting the welding quality. The traditional welding wire manufacturing process uses a wire feeder to promote the core wire. Although the traditional wire feeder has good manufacturing accuracy, it is difficult to maintain a consistent speed, which will lead to the difference between the welding wire diameter and the object to be welded. Therefore, a type of new wire feeder is developed. This new wire feeder alloy is divided into three parts: actuator, driving wheel and silica gel ring. The friction between the silica gel ring and the surface of the core wire can effectively improve the feeding accuracy and ensure the stability of the feeding speed, which is beneficial for ensuring the consistency of the welding wire diameter and the object to be welded.
At the same time, in order to ensure the high efficiency of the manufacturing technology, a coil welding machine is added to this process, which can carry out a large number of welding points at the same time. With the help of a coil welding machine and other automatic devices, the welding efficiency of this process has been significantly improved, and the welding spot quality is also better than before.
Through these improvements, the welding quality of medical core welding wire by turntable method has been greatly improved. It has been widely used in the production of medical instruments and other high-end fields, and its performance has been highly praised by the industry. In the future, further research in this field will be carried out to further improve the manufacturing technology of medical core welding wire by turntable method and make it a more advanced and reliable welding technology.
