Description

Technical Field

[0001] The invention relates to the technical field of wire drawing machines, in particular to a hot drawing wire drawing machine. Background Art

[0002] The wire drawing machine is a mechanical device that uses the principle of elastic deformation and plastic deformation of metal wire during the drawing process to achieve the change of the physical size and characteristics of the metal wire. It is widely used in the production of various steel wires and welding wires in the metal products industry. The hot drawing wire drawing machine heats the metal wire by heating, which is more likely to cause plastic deformation, and then uses the drawing force to draw the metal wire to form metal filaments. For example, the Chinese invention patent with the authorization announcement number CN208019163U discloses a carbon steel metal material wire drawing machine, which includes a wire pay-off roller frame, a wire pay-off roller shaft, a wire pay-off roller, a carbon steel metal wire drawing machine, a wire pay-off roller frame ... Materials, columns, frames, straighteners, heaters, wire drawing dies, metal wires, take-up rollers, pulleys, take-up roller shafts, transmission belts, transmission motors, take-up roller frames, control boxes, straightening motors, straightening boxes, driving wheels, driven wheels, transmission chains, sprockets, linkage chains and linkage sprockets. A column is provided on one side of the pay-off roller frame, and the driving wheel is connected to the sprocket. In the current wire drawing machine, the metal wire needs to be processed through a wire outlet die box to trim the flatness of the metal wire. In order to ensure the quality of the metal wire, the die box usually adopts an angle adjustment structure to ensure the angle of the metal wire in and out, but there are still the following defects:

[0003] At present, the mold box is mostly adjusted by universal adjustment and fixed with auxiliary screws. However, after adjustment, although the angle is more suitable, the corresponding wire entry position will inevitably change, which may easily lead to a large gap between the wire entry position and the wire exit position. The metal wire will be greatly bent when entering the mold box, which may easily cause surface wear and cause defects. In addition, the current wire drawing machines mostly cool the metal wire, but ignore the cooling of the traction wheel itself. The traction wheel contacts the metal wire, which may easily cause the surface temperature to be too high. Long-term use may easily cause the surface of the traction wheel to be heated and compressed, resulting in deformation, affecting the traction effect.

[0004] For this reason, we propose a hot drawing wire drawing machine to solve the above problems. Summary of the invention
