8/450卧式连续拉丝机设计

Design of 8/450 horizontal continuous wire drawing machine

二氧化碳气体保护焊丝和药芯焊丝对直线度要求苛刻。采用卧式连续拉丝机生产,减小了钢丝弯曲,克服了钢丝扭转,钢丝成品直线度好。卧式连续拉丝机组由工字轮放线装置、张紧装置、拉丝机、活套装置、工字轮收线机等组成。最大进线抗拉强度1 200 MPa,最大进线直径4.0 mm,最小出线直径1.2 mm,平均道次压缩率20%,成品最高线速度7.0 m/s,卷筒数量为8个。设计了卧式连续拉丝机传动系统、活套轮及速度反馈系统、卷筒及其冷却系统和模盒装置,经过客户使用,满足拉拔工艺要求。

The carbon dioxide gas shielded welding wire and flux cored wire are strict with straightness.The bending can be decreased and twisting can be eliminated when steel wire is produced with horizontal continuous wire drawing machine.The straightness of finished steel wire is good.Horizontal continuous wire drawing machine set is composed of spool payoff stand,tension device,wire drawing machine,loop device and spool take-up machine and so on.The maximum incoming wire tensile strength is 1 200 MPa,the maximum incoming wire diameter is 4.0 mm,the minimum final diameter is 1.2 mm,average pass draught is 20%,the highest linear speed of finished wire is 7.0 m/s,number of capstan is 8.The transmission system,loop gear and speed feedback system,capstan and its cooling system,die box device of horizontal continuous wire drawing machine were designed.It reached requirements of drawing process after being used by customers.
