1, manual wire drawing: This method is the most primitive manual wire drawing method, without using any mechanical equipment. In operation, the worker puts the metal wire or metal plate into the fixed mold, and then pulls the handle of the mold by hand, so that the metal material can finally form the required shape and size through a series of stretching and deformation operations. The advantages of manual wire drawing are simple operation and low cost, but the production efficiency is low and the stability of precision and quality is not ideal.
2. Mechanical drawing: Mechanical drawing is an advanced drawing process, which uses mechanical equipment instead of manual operation. In mechanical wire drawing, a metal wire or plate is stretched and deformed by one or more stretching wheels and deforming wheels. Mechanical wire drawing has the advantages of high production efficiency, good precision and stable quality, but it requires expensive mechanical equipment, so the cost is high.
3. Hydraulic wire drawing: Hydraulic wire drawing is a new type of wire drawing process, and the traditional wire drawing wheel and deformation wheel are replaced by hydraulic cylinders. Hydraulic wire drawing is to put a metal wire or metal plate into a mold with multiple holes, and then stretch and deform it through the reciprocating motion of a hydraulic cylinder. Hydraulic wire drawing has the advantages of high precision, high production efficiency and low cost, and can produce metal wires or plates with more stable quality.
Application scenarios of manual wire drawing:
1, manufacturing industry: manual wire drawing is widely used in manufacturing industry, such as automobile, aerospace, electronics, construction and other fields. In these industries, manual wire drawing is used to make various metal parts and structural parts, such as automobile engine parts, aircraft wings, electronic components, building steel bars and so on.
2. Jewelry manufacturing: Hand drawing is also widely used in jewelry manufacturing. By hand drawing, metal wires and metal plates of various shapes and sizes can be made, such as precious metals such as gold, silver and platinum, and ordinary metals such as copper, iron and aluminum. These metal materials can be further processed and inlaid to make all kinds of exquisite jewelry and jewelry.
3. Art production: Hand drawing can also be used for art production. By hand drawing, various metal sculptures, murals, decorations and other works of art can be made. These artworks have unique texture and aesthetic feeling, and are widely used for decoration and display in public places, buildings, memorial halls and other places.
