A multi-station crystal bar single-wire cutting machine

Abstract

The invention discloses a multi-station crystal bar single wire cutting machine. The multi-station crystal bar single wire cutting machine comprises a machine frame, a cutting control part, tension control parts, a take-up and pay-off control part, a feeding part and a water storage device, wherein the cutting control part is arranged in the middle of the machine frame; the tension control parts are correspondingly arranged on the portions, on the two sides of the cutting control part, of the machine frame; the take-up and pay-off control part is arranged on the portion, below the tension control parts, of the machine frame; the feeding part is arranged below the cutting control part; and the water storage device is arranged under the feeding part. The multi-station crystal bar single wire cutting machine is simple, compact and reasonable in structure; the scheme that a plurality of workbenches perform cutting at the same time is adopted, the quantity of wires used for cutting can be decreased, and the cutting cost is reduced; and the rising and falling speed of each workbench can be independently controlled, the cutting yield is greatly increased, and the cutting productivity of one multi-station crystal bar single wire cutting machine is equal to that of multiple devices.

Description

technical field [0001] The invention belongs to the technical field of special cutting equipment for crystal rods, in particular to a multi-station crystal rod single-wire cutting machine for cutting crystal rods and other superhard materials with diamond wires. Background technique [0002] At present, the cutting of traditional crystal rods generally has the following disadvantages: [0003] 1) The Mohs hardness of the crystal bar is relatively high, so for a long time, it has been mostly cut with a circular saw blade coated with diamond particles. In order to obtain a better surface quality, the crystal bar is also cut with an internal circular blade coated with diamond particles and a wire saw. Simultaneously, the thinnest thickness of the circular saw blade is also more than 1mm, and the waste of crystal bar material is serious during processing. [0004] 2) The cutting of polysilicon rods is generally carried out by band saws coated with diamond particles. Due to the...

AI Technical Summary

Problems solved by technology

At the same time, the thickness of the thinnest circular saw blade is more than 1mm, and the crystal bar material is seriously wasted during processing.

[0004] 2) The cutting of polysilicon rods is generally carried out by band saws coated with diamond particles. Due to the manufacturing process factors of polysilicon rods, the peripheral surface of polysilicon rods is irregular. Finally, band saws coated with diamond particles are used. Due to the high cutting resistance of the band saw during material cutting, edge chipping is caused on the end surface of the silicon rod, resulting in waste of crystal rod materials such as silicon rods

[0005] 3) Most of the mortar free-cutting methods are used, resulting in a harsh cutting process environment, which is not environmentally friendly, and a large amount of mortar needs to be recycled, which consumes a lot of manpower and financial resources
