Mortar spraying device of crystal multi-wire cutting machine

Abstract

The invention relates to the technical field of a cutting device, in particular to a mortar spraying device of a crystal multi-wire cutting machine. The mortar spraying device comprises a mortar inlet pipe, a stirring pipe, a rotating shaft, blades, a motor, a mortar outlet pipe, a cooling pipe, a mortar spraying pipe, mortar spraying openings and an exhausting opening; the mortar inlet pipe is arranged at two sides above the stirring pipe, the rotating shaft is arranged in the axis of the stirring pipe, the blades are welded on the rotating shaft, and one side of the rotating shaft is connected with the motor; the exhausting opening is formed in the middle position above the stirring pipe, the bottom of the stirring pipe is connected with the cooling pipe by virtue of the mortar outlet pipe, the cooling pipe is communicated with the mortar spraying pipe, a plurality of mortar spraying openings are formed in the bottom of the mortar spraying pipe, and each mortar spraying opening is in a truncated cone shape. By adopting the mortar spraying device, the air content in the mortar can be reduced, the uniformity in mortar spraying is facilitated, the machining quality of crystals is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a spraying device of a crystal multi-wire cutting machine. Background technique [0002] In the field of electronics industry, multi-wire cutting technology is widely used in the processing of crystals. Multi-wire cutting technology uses steel wires sprayed with mortar for cutting. The mortar is mainly composed of silicon carbide and cutting fluid. Using the hard characteristics of silicon carbide and sharp water chestnuts The crystal is cut off, so the quality of the mortar greatly affects the quality of the cut crystal; there are usually air bubbles in the mortar, which will affect the uniformity of the spraying, thereby reducing the processing quality of the crystal; currently, mechanical stirring is used to remove air bubbles during the mortar configuration process , and then enter the mortar circulation system through a series of pipes, and finally sprayed by the s...
