Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, specifically a multi-head wire drawing machine with adjustable single filament tension. Background Technology

[0002] A wire drawing machine is a device used to process metal or other materials into fine wires through a stretching process. It is widely used in industries such as wire and cable manufacturing, metal wire mesh production, and spring manufacturing. Its working principle involves gradually stretching raw materials (such as copper, aluminum, and steel) through a series of dies, reducing their diameter until the desired fine wire is formed. A wire drawing machine typically consists of a feeding device, drawing dies, a take-up device, and a tension control system. During the wire drawing process, controlling the wire tension is crucial. Excessive tension may lead to wire breakage or accelerated die wear, while insufficient tension may cause the wire to slack, affecting product quality and production efficiency. Appropriate tension ensures that the wire maintains uniform stress during the stretching process, avoiding problems such as wire breakage, surface defects, or uneven dimensions.

[0003] Current wire drawing machines primarily use fixed pulleys to guide the output wire for subsequent stretching. They mainly adjust the tension in the middle of the wire feeding process. However, when the wire is fed from the take-up drum, the output position of the wound wire changes repeatedly on the outer wall of the drum. This constant change in output position makes it difficult to adaptively adjust the wire tension, leading to unstable wire output and stretching. Utility Model Content

[0042] By sliding the adjusting slide plate 552 inside the slide rail 551, the seventh pulley 555 is moved horizontally, adjusting the inclination angle and tension of the final output thread, thereby improving the stability of the thread output.

[0043] As one embodiment, the wire feeding assembly 600 includes a rotating shaft 620 that runs through the inside of the wire drawing box 100, two rollers 630 that are sleeved on the outer wall of the rotating shaft 620, and a third motor 610 that is disposed on the outer wall of the wire drawing box 100.

The sliding plate 552 is moved on the slide rail 551 to adjust the relative position of the seventh pulley 555 with respect to the sixth pulley 5437 and the first pulley 420, so as to adjust the tension and inclination angle of the thread during the final feeding.

[0046] Then, during the conveying and stretching of the filament, the initial conveying speed of the filament is controlled by starting the third motor 610, and the pneumatic slide table 510 is started to reciprocate to push the fixed plate 520, so that the second pulley 536 reciprocates to guide the conveying of the filament.

The guide rod 542 slides inside the second fixed frame 5411 to adapt to the conveying tension during the swing.
