Non-uniform-velocity falling-type synchronous taking-up device for producing Dumet wires

Abstract

The invention discloses a non-uniform-velocity falling-type synchronous taking-up device for producing Dumet wires. The device comprises a synchronous constant-speed taking-up wheel, a guide straightening assembly, a falling-type synchronous taking-up barrel and a PLC intelligent control system. The PLC intelligent control system controls the wires to be guided into the guide straightening assembly from the synchronous constant-speed taking-up wheel, and the straightened wires are placed into the falling-type synchronous taking-up barrel. According to the taking-up device for the Dumet wires,the synchronous constant-speed taking-up wheel, the guide straightening assembly, the falling-type synchronous taking-up barrel and the PLC intelligent control system take up the Dumet wires differentin inner diameter, the inner diameters of the taken-up wires can be set to 50-500 millimeters, different demands of clients are conveniently met, and by adopting the device, the damage to the wires in the rolling process can be greatly reduced.

Problems solved by technology

[0002] The red, white, yellow, and boron-free Dumet wires commonly used in the market are used to generate Cu 2 O process is in H 2 Or in the liquefied petroleum gas environment, it is made by heating with ordinary power frequency to 850-1400 °C and then sintering with or without coating. This slow heating generates Cu 2 Coating or non-coating after O coating and re-sintering process generally separates the oxidation furnace for generating cuprous oxide from the surface coating of Dumet wire and the sintering furnace for the sintering process after generating cuprous oxide. The disadvantage of this process is that Good production of cuprous oxide from the oxidation furnace is due to the fact that the surface temperature of the wire material is moved above 400°C in the gap between the wire and the sintering furnace. In this process, it is actually impossible to ensure that 100% of the surface coating layer of Dumet wire is produced. Copper, or, the surface of Dumet wire has more or less fine cracks under the microscope, because it has not been sintered to form Cu 2 O When in contact with the air for a short time, the surface of the Dumet wire will conditionally contact the air and change into a certain proportion of copper oxide factors, and then the sintering process of the sintering furnace has not been coated with PVA anti-oxidation film without gaps layer or (coated with borax (Na 2 B 4 o 7 )) and hot air source drying, such a production process has congenital flaws in controlling the quality of Dumet products, which can easily affect the 100% compactness and special Storage conditions, which lead to the increase of unstable factors of downstream product quality, and reduce the overall economic benefits of society

Moreover, the Dumet silk prepared by this process adopts the ordinary winding method to wind and pack the produced Dumei silk. Because the speed in the winding process is not easy to control, on the one hand, it is easy to cause the Dumei silk to be damaged during the winding process. It is easy to damage the quality and affect the quality of Dumet silk; on the other hand, it cannot be flexibly adjusted according to the required inner diameter of the wire, which cannot meet the needs of customers, so it needs to be improved
