Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing dies, in particular to a wire drawing die mechanism with adjustable aperture. Background Art

[0002] Wide flat alloy wire, also known as flat wire, flattened wire, flat-angle wire or ultra-narrow strip, refers to a special-shaped metal wire with a cross-section that is approximately a rounded rectangle. The thickness ranges from 0.025mm to 2mm, and the width is generally less than 5mm. Its width-to-thickness ratio varies from 2:1 to 50:1. Due to its ribbon-like shape, flat wire is sometimes also called ultra-narrow flat strip. Compared with common round wire, flat wire has unique advantages in heat dissipation, welding contact area, fatigue resistance, hardness control, etc. Traditional wire drawing dies are mostly made as a whole. When encountering different processing apertures, multiple wire drawing dies are required. In this way, the entire die needs to be replaced later, which not only wastes a lot of material for making the die, but also has a high cost of damage. For this reason, we propose a wire drawing die mechanism with adjustable aperture. Utility Model Content
