Wet wire drawing machine with automatic cooling circulation of coolant

Abstract

The invention discloses a wet wire drawing machine with automatic cooling circulation of a coolant. The wet wire drawing machine comprises a drive mechanism, a rack and a cooling circulation box, wherein a driving belt pulley is arranged at the output end of the drive mechanism; a guide wheel group shaft, a low-speed cone pulley transmission shaft, a high-speed cone pulley transmission shaft and a wire feeding shaft are installed in the rack at intervals; a driven belt pulley is arranged on the high-speed cone pulley transmission shaft in a sleeving manner; the driving belt pulley is connected with the driven belt pulley through a first belt in a driving manner; a fourth synchronous belt pulley and a wire feeding drum are arranged on the wire feeding shaft in the sleeving manner; a water channel is formed in the rack; and a heat exchanger, a liquid return tank, a settling tank, a pump, a cooling tank and a liquid storage tank are arranged in the cooling circulation box. The wet wire drawing machine with automatic cooling circulation of the coolant can ensure automatic cooling circulation of the coolant, so that the temperature, required by production, of the coolant is reached, the cooling effect of a steel wire is ensured, the energy is saved, and the quality of a product is also guaranteed.

Description

technical field [0001] The invention relates to a water tank wire drawing machine, in particular to a water tank wire drawing machine with automatic cooling circulation of cooling liquid. Background technique [0002] The water tank type wire drawing machine is a small continuous production equipment composed of multiple drawing heads. After drawing step by step, and placing the drawing heads in the water tank, the steel wire is finally drawn to the required specifications. As far as several major domestic water tank-type wire drawing machine manufacturers are concerned, they are generally equipped with about 20 drawing heads. After each level of drawing, the wire diameter of the steel wire has changed, so the working line speed of each drawing head should also change. During the working process of the water tank type wire drawing machine, cooling liquid is needed to dissipate heat. If the cooling is insufficient, the temperature of the steel wire will rise, the strain agin...

AI Technical Summary

Problems solved by technology

During the working process of the water tank type wire drawing machine, cooling liquid is needed to dissipate heat. If the cooling is insufficient, the temperature of the steel wire will rise, the strain aging time will be short, and the deterioration trend of the mechanical properties of the steel wire will increase. If the strength increases and the twist value decreases, it will easily produce torsional cracks etc.

[0003] The cooling system of the existing water tank wire drawing machine cools down by natural cooling, which leads to the temperature of the cooling liquid being too high, the cooling effect is poor, the loss of the phosphating layer on the surface of the steel wire is accelerated, and the friction increases, which not only increases the heating of the steel wire, but also affects the quality of the product. Decrease, product pass rate decline

In addition, the existing water tank wire drawing machine needs to stop when the wire reaches a certain weight, unload the finished product, replace the empty frame, restart the machine, and cycle in turn

The wire drawing machine is prone to disconnection during the start-up and shutdown process, and it takes time and effort to change the frame, which reduces the production efficiency
