一般拉丝机的拉丝速度有单速和多速之分。单速的应用范围小,在设备较全的企业是无所谓的,对不同的钢丝材料和钢丝规格可选用不同的设备;而在那些材质种类多,线材规格多的科研单位和拉丝设备规格较少的单位就需要一种变化速度多的设备;因为不同的材质和线径就需要不同的拉丝线速度。对设备制造单位来说,要使拉丝机有几种不同的线速度,就得有变速机构。变速机构种类很多,如:齿轮传动机构;皮带传动变速机构;还有多速电动机变速等等。这些变速机构的速度种类也有一定的限制。过去我厂生产的LT—10/350水箱拉丝机有12种线速度,这是比较先进的。但这种变速机构较复
Drawing speed of the general drawing machine with single-speed and multi-speed points. The application range of single speed is small. It does not matter in enterprises with complete equipment. Different equipment can be used for different specifications of steel wire and steel wire. In research institutes and wire drawing apparatuses with more kinds of materials and more wire specifications, Units need a device that changes at a faster rate; because different materials and diameters require different wire draw speeds. Equipment manufacturing units, to make the drawing machine has several different linear speeds, you have to have a speed change mechanism. Many different types of gearboxes, such as: gear drive; belt transmission speed change mechanism; there are multi-speed motor speed change and so on. The speed of these types of speed agencies also have some restrictions. In the past I produced LT-10/350 water tank drawing machine has 12 kinds of linear speed, which is more advanced. But this speed change mechanism is more complex
