随着电缆行业发展需要、电缆产品种类的多样化以及客户对电缆产品的特殊需求型,电缆类模具的种类及要求也逐渐增加。目前,电缆行业涉及到的模具较多的有:拉丝、绞合模具;紧压成型模具、成缆模具;挤出模具等。下面我们对电缆行业常用模具进行大概梳理,并针对我们工作接触较多的模具进行解读。
With the development of the cable industry, the diversification of cable products and the special needs of customers for cable products, the types and requirements of cable moulds are gradually increasing. At present, there are many molds involved in the cable industry: wire drawing and stranding mold; compression molding mold, cable forming mold; extrusion mold, etc. Now we sort out the commonly used molds in the cable industry, and interpret the molds that we work with more.
二、拉丝、绞合模具的种类、性能及应用
2、 Types, properties and application of drawing and stranding dies
2.1 此类模具一般称为线模,可分圆模和型模,常用线模材料有钻石模、硬质合金模、聚晶模等。
2.1 this kind of mold is generally called wire mold, which can be divided into round mold and mold mold. The commonly used wire mold materials include diamond mold, cemented carbide mold, polycrystalline mold, etc.
a钻石模:钻石模也称金刚石,具有最高的硬度,耐磨,但价格较贵。在拉丝中,一般用在拉小规格单丝,如Φ0.40mm及以下规格。
A diamond mold: diamond die, also known as diamond, has the highest hardness, wear resistance, but the price is more expensive. In wire drawing, it is generally used to draw small size monofilament, such as Φ 0.40mm and below.
b硬质合金模:在拉伸生产中,过去使用的钨钢模全为硬质合金模所代替的。因为硬质合金模拉伸模与钢模相比具有:耐磨性较好,抛光性好、对被加工金属的粘附性小,摩擦系数小,导热系数高和具有很高的耐腐蚀性。
B cemented carbide die: in drawing production, the tungsten steel dies used in the past were all replaced by cemented carbide dies. Compared with the steel die, the drawing die of cemented carbide die has the following advantages: good wear resistance, good polishing performance, small adhesion to the processed metal, small friction coefficient, high thermal conductivity and high corrosion resistance.
c 聚晶模:也称人造钻石,是目前最常用的模丝模,它具有耐磨性,但也有不足之处就是生产出产品表面不光滑。
C polycrystalline mold: also known as synthetic diamond, is currently the most commonly used mold wire mold, it has wear resistance, but there are also shortcomings in the production of product surface is not smooth.
