Wire-drawing die ultrasonic polishing device

Abstract

The invention relates to a wire-drawing die ultrasonic polishing device. The wire-drawing die ultrasonic polishing device comprises a working table, and further comprises an ultrasonic vibration mechanism, a lifting mechanism, a rotating mechanism and a grinding mechanism arranged on the working table. The ultrasonic vibration mechanism is used to support a wire-drawing die, and can drive the wire-drawing die to conduct high-frequency vibration by means of ultrasonic driving. The rotating mechanism is arranged on the moving part of the lifting mechanism and used for fixing a tool needle, and can drive the tool needle to rotate. The lifting mechanism is arranged above the ultrasonic vibration mechanism and is used to drive the rotating mechanism to make a reciprocating movement relative tothe ultrasonic vibration mechanism. The grinding mechanism is used for grinding the tool needle fixed on the rotating mechanism. The wire-drawing die ultrasonic polishing device adopts the way of theultrasonic driving vibration of the wire-drawing die and rotating driving of the tool needle to achieve the polishing operation of die core holes on the wire-drawing die, so that the polishing qualityof the ultrasonic polishing device during the polishing operation of the wire-drawing die is ensured, and the finished product rate is improved.

Description

technical field [0001] The invention belongs to the technical field related to ultrasonic processing equipment, in particular to an ultrasonic polishing device for a wire drawing die. Background technique [0002] Wire drawing die refers to a tool that forces metal to pass through the die under the action of external force in metal pressure processing, the cross-sectional area of ​​the metal is compressed, and the required cross-sectional shape and size are obtained. [0003] It can be understood that in the process of wire drawing die manufacturing, the processing technology widely used now is to use ultrasonic polishing equipment for finishing after laser roughing the die core hole, so as to improve the surface quality of the die core hole and reduce wire drawing resistance and wire rod scrape. [0004] At present, the polishing machine used for the polishing of the core hole of the wire drawing die is a semi-automatic ultrasonic shaping and polishing machine for diamond ...

AI Technical Summary

Problems solved by technology

The length and quality of the tool needle determine the natural frequency of the system, which will increase the natural frequency of the entire system, and the power supply cannot match the system frequency, causing the tool needle to generate lateral vibration or bending torsional vibration that seriously affects the processing quality. Cause processing quality to decline, yield rate is extremely low
