preparation example Construction

[0029] The invention provides a method for preparing a diamond wire saw, comprising the following steps: (1) performing polarization treatment on the surface of the diamond wire; (2) spreading the diamond wire after the polarization treatment in step (1) around the vertical embryo wire , the embryonic wire and the emery move downwards and make the emery adhere to the embryonic wire through an electrostatic field; (3) electroplating the embryonic wire adhered to the emery obtained in step (2) to obtain a diamond wire saw.

[0030] In the preparation method of the above-mentioned diamond wire saw, the corundum needs to be adhered to the embryonic wire through electrostatic action, so before the emery is used, it is firstly subjected to polarization treatment, so that the emery can better adhere to the embryonic wire in the electrostatic field . Continuously and evenly spread the corundum around the embryonic wire, and control its spreading density and range, so that the emery an...

Embodiment 1

[0050] A preferred embodiment of the present invention provides a method for preparing a diamond wire saw, comprising the following steps: (1) using a chemical method to polarize the surface of the emery with a particle diameter of 10 μm to cover it with a non-metallic layer; The surface of the embryonic thread is cleaned, dried and pretreated to keep the surface of the embryonic thread active. (2) Continuously disperse the above-mentioned corundum in the loose sand barrel 3, and spread the corundum evenly in the loose sand barrel 3 by stirring, and the density of the corundum around the embryo line is 30 cts / cm 3 , the embryo line and emery pass through the loose sand barrel 3 downwards and enter the upper sand barrel 4. The line speed of the embryonic line is 30m / min through the electrostatic field, and the direction of the electrostatic field is perpendicular to the embryonic line and points to the embryonic line from all around, with a strength of 1×10 6 v / m. (3) The emb...

Abstract

The invention discloses a preparation method and a device of a diamond wire saw. The preparation method comprises the following steps (1) polarizing surfaces of carborundums; (2) dispersing the polarized carborundums in the step (1) around a vertical blank line, downwards moving the blank line and the carborundums, and adhering the carborundums onto the blank line through a static electric field;and (3) electroplating the blank line adhered with the carborundums obtained in the step (2), and obtaining the diamond wire saw. According to the preparation method of the diamond wire saw, the problem that the carborundums are instable to suspend in an electroplate liquid is solved, the utilization ratio of the carborundums is improved, and the sand feeding efficiency is high; a sand feeding effect decides the size of the static electric field, the routing speed of the blank line and the loose sand density around the blank line; and according to the preparation method, the ability to regulate and control the sand feeding effect is improved, and the production efficiency of the diamond wire saw is improved.

Description

technical field [0001] The invention relates to the technical field of diamond tool processing, in particular to a preparation method and device of a diamond wire saw. Background technique [0002] Diamond tools are widely used in the processing of hard and brittle materials, but the production efficiency and quality are difficult to guarantee, mainly because the production technology is immature. At present, the manufacturing technology of diamond wire saws generally has the following types: the steel wire, that is, the embryo wire, passes through the accumulated emery, and the diamond wire saw is manufactured by electrification, sanding, and electroplating; Mixed solution, electrified and sanded to make diamond wire saw; embryonic wire is made of diamond wire saw by sanding under the action of magnetic field and electric field through electroplating mixed solution mixed with a certain proportion of diamond in an external magnetic field. The manufacturing technology of the...
