A wire drawing and annealing device for a sub-motor

Abstract

One or more embodiments of this specification provide a wire drawing and annealing device for split motors, including a wire drawing main frame, which divides the two sides of the wire drawing main machine into a driving chamber and an annealing chamber through a frame, and the feeding wheel is coaxially fixed to the output shaft of the feeding motor through the The annealing wheel is coaxially fixed to the end where the output shaft of the annealing motor enters the annealing room. The annealing wheel groove is surrounded by a nickel belt, and the wire drawing host is equipped with an annealing power supply for contacting the short-circuit nickel belt. In order to generate high temperature, the copper wire is sequentially wound through the feeding wheel and annealing wheel to continuously draw and anneal on-line. The end near the annealing wheel is equipped with a pre-adjustment mechanism, and the copper wire is passed through the pre-adjustment mechanism. The wire diameter of the copper wire is sensed, and the pre-adjustment mechanism is electrically connected to the annealing motor, so that the sensed wire diameter is used to pre-adjust the working current of the annealing motor through feedback, so as to realize the function of real-time preset wire tension.

[0002] The wire drawing annealing machine is based on the original wire drawing machine plus online annealing. The product is formed at one time to improve the production efficiency. It is mainly used in the copper wire drawing industry, brass wire drawing industry, aluminum wire drawing industry, and copper-clad copper wire drawing industry. This type of equipment can be used for wire drawing of non-ferrous metals, but how to control the constant wire tension has become a long-term common problem in wire drawing annealing production. Among them, for the continuous wire drawing annealing of copper wire, on the one hand, due to the wire itself diameter, there will inevitably be some deviation or unevenness. On the other hand, due to the annealing of the copper wire, the ductility becomes better, and it may also have intermittent and irregular diameters when it is stretched. The thickness of the wire diameter is also one of the factors that affect the stability of the drawing wire tension, which can cause the copper wire to be loose and tight when drawing the wire, or even slightly shake or slip, thus affecting the drawing quality of the copper wire, and the copper wire is slightly damaged during annealing. Vibration or slippage can also easily cause friction and ignition, thus affecting the surface appearance of the copper wire. In the prior art, there are few related measurement and control fine-tuning devices that are specially aimed at the change of the diameter of the copper wire to affect the tension of the drawing wire, so as to further improve the drawing annealing. Stable tension control in production, and the existing tension control device often has a certain hysteresis, often by sensing the tension change, to achieve feedback adjustment, so that it cannot solve the tension change belt in a more timely and efficient manner. The drawing quality and the wear and tear of the wire surface
