Ring type consolidated diamond scroll saw cutting device and workpiece cutting method

Abstract

A ring-type consolidated diamond wire saw cutting device, which is connected with an ultrasonic vibration device, includes: a wire saw unit with a drive mechanism, at least one guide wheel, and a wire saw wire that surrounds the drive mechanism and the guide wheel and forms a closed loop, and drives The mechanism drives the wire saw wire to make the main cutting movement; the feed unit is connected with the wire saw unit and is used to drive the wire saw wire to move along the direction perpendicular to the main cutting motion of the wire saw wire; the workpiece fixing unit is fixedly arranged on the feed unit In the moving direction, it is used to fix the workpiece. The workpiece fixing unit has: a fixed fixture; a horn arranged on the fixture and connected to the ultrasonic vibration device is used to amplify the high-frequency vibration input by the ultrasonic vibration device, and the fixture clamps the workpiece and is in contact with the horn. The horn connected with the ultrasonic vibration device applies vibration to the workpiece, causing the workpiece to vibrate ultrasonically, so that the workpiece has a continuous impact on the wire saw wire, which reduces the difficulty of the wire saw wire cutting into the workpiece, thereby improving processing efficiency.

Description

technical field [0001] The invention relates to a wire saw cutting device and a corresponding cutting method, specifically belonging to the technical field of wire saw cutting. Background technique [0002] With the rapid development of industry, the application of hard and brittle materials in various fields is becoming more and more common. Hard and brittle materials mainly include various gemstones, glass, silicon crystals, ceramics, etc., which have excellent properties such as high hardness, high brittleness, and high wear resistance. However, if the processing method is not selected properly, the low plasticity and brittleness of hard and brittle materials will easily cause the surface layer of the workpiece to be damaged. In the processing of hard and brittle materials, sawing is often the first process and occupies a very important position. For this reason, diamond circular saws, band saws, wire saws and other equipment are usually used for sawing hard and brittle...

Problems solved by technology

[0004] In the prior art, the force between the wire saw wire and the workpiece is mainly provided by the wire saw wire extruding and cutting the workpiece. The opening angle of the wire saw wire will increase with the increase of the sawing force, and the greater the opening angle The more unstable the wire saw wire, the lower the processing efficiency and processing quality
