介绍生产φ0.2毫米以下金属丝的新方法。挤压法:用一钝角的金刚石模具逆流顶推运动着的原料,原料局部形成高压区,金属丝即从模孔内射出。模孔抛光,精度高;模孔形状决定了金属丝断面,产品组织均匀细微。原料长L,生产l长产品,l/L叫线性收得率,它取决于金属性质、加工温度、加工硬化率、进线径、模具形状、穿入深度、模径和润滑条件等。 Describes a new method of producing wires up to 0.2 mm in diameter. Extrusion method: With an obtuse diamond countercurrent counter-current to promote the movement of raw materials, raw materials to form a high pressure part of the local area, the wire that is emitted from the die hole. Die hole polishing, high precision; die hole shape determines the wire cross-section, product organization and subtle. L long raw material, l long product, l / L is called the linear recovery rate, which depends on the nature of the metal, processing temperature, hardening rate, into the wire diameter, mold shape, penetration depth, die diameter and lubrication conditions.
