Description

Technical Field

[0001] This utility model relates to the field of wire drawing machines, and specifically to a tension adjustment device for a wire drawing machine. Background Technology

[0002] A wire drawing machine is a piece of equipment used for processing metal wires. Depending on the diameter and material of the wire, it can be divided into large drawing machines, medium drawing machines, small drawing machines, fine wire drawing machines, and micro-fine wire drawing machines. Common wire drawing machines include straight-in wire drawing machines, suitable for drawing high, medium, and low carbon steel wires, stainless steel wires, copper wires, and other materials. They are characterized by high efficiency and precision. Wire drawing machines have a wide range of applications, mainly for the pre-processing of metal products, such as the production of standard parts. In addition, wire drawing machines can also be used in the plastics industry, such as for the deep processing of hollow and solid round or flat wires made of polyester, nylon, polyethylene, etc. A Chinese patent discloses a copper-clad aluminum wire drawing machine with a tensioning device (authorization announcement number CN). Patent 214263623U describes a counterweight disc that drives a slider to slide within an arc-shaped groove. This pushes the inclined block back into a guide groove, and the elastic rubber strip resets, driving the insert block to insert into the slot along the guide groove, completing the installation of the counterweight disc. The drive handle then drives the insert block and the inclined block to fully retract into the guide groove. Rotating the counterweight disc moves the slider into a sliding groove, driving the counterweight disc to disengage from the counterweight shaft, completing the disassembly of the counterweight disc. However, this design uses a tensioning wheel to tighten the wire under its own weight, thus adjusting the tension. Since the weight of the tensioning wheel is fixed, it cannot adjust the tension for different wires, making subsequent tension adjustments impossible. Therefore, those skilled in the art have provided a tension adjustment device for a wire drawing machine to solve the problems mentioned in the background art. Utility Model Content

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. When the tension of the wire drawing machine needs to be adjusted, the fixed shaft of the connecting handle moves in a circular motion in the circumferential groove by rotating the turntable clockwise. The adjusting shaft moves in the adjusting groove, and the position of the tensioning wheel changes accordingly. The operation is simple and the adjustment efficiency is improved.

[0010] 2. For different types of wire, the turntable can be adjusted to the appropriate angle according to the required tension. At this time, the tensioning wheel reaches the appropriate position.
