Reciprocating cutting machine through diamond wire

Abstract

The invention discloses a reciprocating cutting machine through a diamond wire. The reciprocating cutting machine comprises a base frame, the diamond wire which is arranged on the base frame and usedfor cutting a silicon rod and a limiting assembly which is used for achieving reciprocating cutting of the diamond wire, and the diamond wire is wound in the limiting assembly to form a reciprocatingcutting position. According to the reciprocating cutting machine through the diamond wire, the limiting assembly is arranged to limit the diamond wire to always have a short stress supporting point atthe reciprocating cutting position, so that the cutting length of the diamond wire at the reciprocating cutting position is kept stable as much as possible, the size of a wire bow in the cutting process is controlled, the cutting strength of the diamond wire at the reciprocating cutting position is improved, reduction of the cutting efficiency due to overlarge wire bow caused by reversing cuttingis avoided, reciprocating cutting is carried out on the silicon rod at the reciprocating cutting position, the tool retracting process in multi-section cutting of the silicon rod is omitted, the cutting speed is increased, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of silicon rod cutting equipment, in particular to a diamond wire reciprocating cutting and cutting machine. Background technique [0002] The existing monocrystalline silicon rod single-wire cutting machine has poor cutting quality for silicon rods, which is likely to cause edge chipping and poor parallelism, which affects the subsequent processes of square cutting, grinding and slicing of silicon rods, and the existing The cutting head of the single-crystal silicon rod single-wire cutting machine cannot realize reciprocating cutting. There needs to be a knife retraction process between the two cutting actions, which affects the cutting efficiency. lifespan is also affected. [0003] Therefore, prior art still needs further development and improvement. Contents of the invention [0004] Aiming at various deficiencies in the prior art, in order to solve the above problems, a diamond wire reciprocating cu...
