Wire polishing device

Abstract

The invention relates to a wire polishing device, which comprises a rotating fixing mechanism, a polishing mechanism and a moving bracket. The rotating fixing mechanism is used for fixing a wire-drawing die and can drive the wire-drawing die to rotate; the polishing mechanism comprises a metal wire penetrating through a die hole of the wire-drawing die, and two ultrasonic vibration generators arranged at the two ends of the metal wire correspondingly; vibration output parts of the two ultrasonic vibration generators and the metal wire are connected and fixed; and the two ends of the polishingmechanism are fixedly connected to the moving bracket, moving of the moving bracket drives the polishing mechanism to do reciprocating motion relative to the rotating fixing mechanism, and thus the wire-drawing die is polished. According to the wire polishing device, high-frequency ultrasonic vibration in the length direction of the metal wire is increased while the metal wire makes the reciprocating motion, the effect of reducing resistance of the metal wire is achieved, the metal wire also conducts high-frequency vibration to abrasive particles brought into a wire-drawing die hole sizing area, and thus the polishing efficiency and the polishing quality of the wire polishing device on the wire-drawing die are improved.

Description

technical field [0001] The invention belongs to the technical field related to polishing processing equipment, in particular to a line polishing device. Background technique [0002] A wire drawing die usually refers to a die used to draw various metal wires or optical fibers, wherein the center of the wire drawing die has a die hole of a certain shape, round, square, octagonal or other special shapes, and metal wires, optical fibers, etc. The wire is manufactured by passing through the die holes step by step from large to small, so that the size becomes smaller and even the shape changes. [0003] It can be understood that the die hole on the wire drawing die is initially processed by laser processing or EDM. In order to reduce the resistance of the wire drawing process and improve the surface quality of the metal wire, a polishing process is also required. At present, the polishing of the sizing area of ​​the upper die hole of the existing wire drawing die generally adopt...

Problems solved by technology

[0005] However, when the wire polishing machine of the above-mentioned special-shaped wire drawing die is in operation, because the mechanical reciprocating motion of the metal wire drives the abrasive grains or grinds for reciprocating grinding, the resistance to the wire is large, which makes the wire scratch seriously, making the metal The wire wears fast, so it is difficult to ensure the stability and consistency of the polishing process. It is also difficult to guarantee the shape and position accuracy of the corresponding wire drawing die hole. And the corresponding polishing time is long and the efficiency is low
