Description
Technical Field
The invention relates to a die changing technology of a wire drawing machine, in particular to a wire drawing machine with an online tension detection device and a die changing method.
Background
In the current steel cord wire drawing production process, the wet drawing process needs to draw the brass-plated steel wire with the large diameter in a lubricating liquid to obtain the thin steel wire with the specific specification. The friction force of the wet drawing die in the drawing process is different under different specifications, and the wet drawing die can be worn in the production process. When the die is worn to a certain extent, the resistance of the steel wire in the die can be changed, and the plasticity of the produced steel wire can be obviously reduced. The prior art means is to replace the mould periodically to prevent the situation of overlarge friction force of the steel wire in the drawing process.
Problems and disadvantages of the prior art:
At present, the wet drawing has no tension monitoring equipment and standard in the production process, and the wet drawing can only replace a wet drawing die periodically to stabilize the performance of the steel wire. Periodic mold changing has two disadvantages.
1. Because tension monitoring is not available at present, the abrasion condition of the wet drawing die is not known, and only the wet drawing die can be replaced periodically, so that the utilization rate of the wet drawing die is low, and the wet drawing die cannot be fully used. And simultaneously, the die changing frequency and abrasion of personnel can be increased, and the man-hour and the cost of expendable products in the production process are increased.
2. At present, the wet drawing is not monitored on the abrasion of a wet drawing die, so that the compression ratio of individual passes of the steel wire is abnormal in the drawing process, and the strength and the plasticity of the steel wire are affected. When the strength of the steel wire is higher and the plasticity is reduced, the condition of wire breakage easily occurs in the production process of the cord, and thus the production efficiency of the cord and the scrapping of the steel wire can be influenced.

The wet drawing process is multi-mode continuous drawing production, the thicker electroplated brass steel wire is gradually thinned to the required steel wire diameter of the cord through a multi-pass die, and the steel wire can receive pressure, friction force and drawing force in the whole drawing process. When the wet drawing die is worn, the drawing force of a single pass is increased, and the friction force is also increased.
