Ultrasonic machining device and machining method for diamond microporous wire-drawing die

Abstract

The invention discloses an ultrasonic machining device and a machining method for a diamond microporous wire-drawing die, aiming at the problem of frequent needle breakage during machining for a diamond microporous wire-drawing die in the prior art. The ultrasonic machining device mainly comprises a three-dimensional tool needle adjustment mechanism, a die alignment mechanism, and an observation / detection / correction system, wherein a tool needle and the die can be aligned respectively by taking the centre of a rotary workbench as the reference of the alignment operation and by virtue of the observation / detection / correction system. In addition, the ultrasonic machining device can provide a balanced machining pressure by combining with a balanced elastic pressure adjustment mechanism, so that the occurrence of frequent needle breakage during a machining process for the diamond microporous wire-drawing die can be avoided; the ultrasonic machining device is especially suitable for machining the diamond microporous wire-drawing die with the pore diameter of not greater than 0.03 mm, and capable of improving the machining stability and the reliability, thus ensuring the machining quality of the diamond microporous wire-drawing die and increasing the machining efficiency of the diamond microporous wire-drawing die.

Description

technical field [0001] The invention relates to an ultrasonic processing device, in particular to an ultrasonic processing device suitable for processing diamond micro-hole wire drawing dies, and also relates to a processing method using the device to realize grinding and polishing of diamond micro-hole wire drawing dies, which belongs to special processing technology field. Background technique [0002] Wire drawing is a metal processing method that forces the metal to pass through the mold under the action of external force, the metal cross-section is compressed, and the required cross-sectional shape and size are obtained. A wire drawing die is a tool that changes the shape and size of the metal cross section. The hole shape of the wire drawing die is composed of entrance, lubrication, compression, sizing, reverse taper, exit and other areas with different angles and tapers, which is relatively complicated. The diameter of the wire drawing die, the precision of the hole...

Problems solved by technology

For molds with smaller apertures, due to the small size of the tool pins, it is more difficult to adjust the tool pins and the mold to be processed relative to the rotary table. During the dynamic adjustment process, it is easy to break the pins.

[0006] Therefore, the processing method of mold floating and centering can still be used barely for the wire drawing die with an aperture of about 0.05mm, but for the diamond microporous wire drawing die with an aperture of ≤0.03mm, because the tip of the tool needle is too thin, it is difficult to find and press in the center. During the adjustment process, the problem of easy broken needles becomes an unavoidable obstacle

During the operation, frequent needle folding will make the processing impossible

In the prior art, there are no other better solutions
