What is wire drawing? Principle, classification, process, advantages and application of wire drawing
Ⅰ Introduction to drawing
Wire drawing process, as a metal surface treatment technology, is mainly to form fine and uniform scratches or lines on the metal surface by mechanical means to achieve the purpose of decoration, anti-slip, deburring or improving the surface reflection characteristics.
Ⅱ Drawing sort
According to the different mode of operation and effect, the drawing process can be divided into many types, mainly including:
1. Linear wire drawing
The use of linear wire drawing machine in the metal surface along the fixed direction for linear scratch processing, commonly seen in mobile phone bezels, home appliance panels and other requirements of linear texture beautiful occasions.
2. Random wire drawing
through special tools or equipment, random and staggered scratches are generated on the metal surface to form a unique texture, which is suitable for products that need to create rough and retro style.
3. Spiral wire drawing(also known as spinning wire drawing)
The use of rotating rollers or brushes to carry out circular motion on the metal surface to form spiral-like lines, which are commonly seen in high-end kitchenware, decorations and other fields.
4. Corrugated wire drawing
through a specific mold or tool to press a wavy, undulating texture on the metal surface, suitable for scenes with special visual effects needs.
Ⅲ Process flow
The basic process of wire drawing process includes: pretreatment (cleaning, oil removal, rust removal), selection of wire drawing tools and equipment, adjustment of parameters (such as speed, strength, Angle), wire drawing operation, post-treatment (cleaning, polishing, rust prevention treatment, etc.), quality inspection. Each step requires strict control to ensure the surface quality and consistency of the final product.
Ⅳ Drawing advantage
1. Enhance aesthetics: The brushed metal surface presents a unique texture effect, improving the visual layer and texture of the product.
2. Improve wear resistance: subtle scratches can reduce the direct friction of the metal surface, thereby enhancing wear resistance and extending service life.
3. Remove burrs: effectively remove burrs generated during metal processing, making the product edges smoother.
4. Improve hand feel: Appropriate drawing treatment can significantly improve the touch of the product and increase the comfort of holding.
Ⅴ Influencing factor
1. Material properties: Different materials of metal have different responses to the drawing effect, such as hardness, toughness, ductility, etc., which will affect the final texture effect.
2. Process parameters: drawing speed, strength, Angle, tool material and other factors directly determine the depth, thickness and uniformity of the texture.
3. Environmental conditions: the temperature, humidity and cleanliness of the operating environment may also have a certain impact on the drawing effect.
Ⅵ Matters needing attention
1. Precise control: In the drawing process, it is necessary to accurately control the process parameters to avoid quality problems caused by improper operation.
2. Environmental safety: Choose environmentally friendly drawing tools and materials, ensure that the working environment is well ventilated, pay attention to personal protection, and avoid dust and noise pollution.
3. Follow-up protection: Timely cleaning and anti-rust treatment should be carried out after wire drawing to prevent the metal surface from being oxidized or corroded, affecting the beauty and service life.
4. Quality inspection: Strict quality inspection of the finished products to ensure that each process meets the standards to ensure the quality of the final products.
