Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automatic threading machines, in particular to a medium-speed wire automatic threading machine. BACKGROUND

[0002] The working principle of the medium-speed wire automatic threading machine is that through a precise control system and an automatic mechanical structure, the automatic threading and conveying process of molybdenum wire (electrode wire) is realized. This process is highly automated, significantly improves production efficiency, and reduces errors caused by manual operation. Specifically, the medium-speed wire automatic threading machine uses a photoelectric sensor to detect a small hole on a workpiece and transmits a signal to a control system. The control system then activates an automatic threading mechanism and a wire conveying mechanism. During the automatic threading process, the threading device accurately aligns with the small hole position, and the molybdenum wire is quickly threaded through the small hole by pressure and current action, and subsequent conveying and positioning are completed.

[0003] The advantages of the medium-speed wire automatic threading machine mainly include the following aspects:

[0004] High precision: thanks to the precise control system and mechanical structure, the medium-speed wire automatic threading machine can achieve high-precision threading and positioning, ensuring that the size and shape of the workpiece meet strict requirements;

[0005] High efficiency: automated operation significantly shortens the threading time and improves overall processing efficiency. At the same time, it reduces human intervention and avoids errors and delays caused by human factors;

[0006] Reduced labor costs: automatic threading machines reduce the dependence on skilled workers and reduce labor costs for enterprises. Workers can devote more energy to other more valuable tasks;

[0007] Improved product quality: the automatic threading process is stable and reliable, reducing quality problems caused by improper human operation. At the same time, high-precision threading and positioning help improve the overall quality of products;

[0008] Enhanced equipment safety: automatic threading machines are usually equipped with safety features such as power-off protection and collision protection, which can stop working in time when abnormal situations occur to protect the safety of equipment and operators.

[0009] The inventor found that the following problems in the prior art have not been well solved in the process of implementing the scheme:

[0010] The rolling cylinder for winding molybdenum wire has a horizontal reciprocating effect, the surface of the winding roller contains a line fixing structure which fixes the end of the wound molybdenum wire on the lower roller wall, which can fix the end of the molybdenum wire, but the position of the structure on the roller is fixed, since the molybdenum wire end is wound and fixed, it is impossible to leave a little length every time, in most cases, it will leave a long length, and this length is not enough to wind a circle on the roller again, so the staff needs to use scissors to cut the fixed line and the excess part, although it is convenient to operate, but it will cause the waste of molybdenum wire, since the molybdenum wire will be elongated after use, so it needs to be cut frequently, which causes unnecessary waste, therefore, a middle wire automatic threading machine is provided.
