Wire rod surface preparation device

The utility model belongs to the technical field of the wire drawing machine, a wire rod surface preparation device is provided, including the rotary drum of not filling full burnish sand, set up bearing roller and drive drum pivoted drive arrangement at the rotary drum both ends, it has the wire guide that makes the wire rod pass to open at rotary drum both ends, the axis of wire guide and the axis collineation of rotary drum, burnish sand's filling height is higher than the height of wire guide. The rotary drum that is equipped with burnish sand through the drive rotates, makes burnish sand flow in the rotary drum to the replacement cycle who makes burnish sand prolongs greatly, no longer need change burnish sand frequently, and labour saving and time saving has improved production efficiency. 本实用新型属于拉丝机技术领域，提供了种线材表面预处理装置，包括未填充满研磨砂的转筒、设置在转筒两端的托辊和驱动转筒转动的驱动装置，在转筒两端开有使线材穿过的导线孔，所述导线孔的轴线与转筒的轴线共线，所述研磨砂的填充高度高于导线孔的高度。通过驱动装有研磨砂的转筒转动，使研磨砂在转筒内流动起来，从而使研磨砂的更换周期大大延长，不再需要频繁地更换研磨砂，省时省力，提高了生产效率。
