Problems solved by technology

[0003] Pulleys and pulley pieces are often used in diamond wire cutting machines. When the current pulleys and pulley pieces are produced, there are many wire breakages caused by the influence of pulleys on the steel wire take-up and pay-off, and the cutting service life of the main pulley is not long.

Embodiment

[0021] A kind of preparation method of diamond wire cutting machine pulley sheet of the present embodiment, comprises the following steps:

[0022] (1) Clean and degrease the pulley frame to be processed;

[0023] (2) Cutting the polyethylene bar, the cutting length is 300-330mm, and the polyethylene ring is obtained;

[0024] (3) Use a machine tool to hollow out the cut polyethylene ring along the axial direction. After the hole is drilled, the diameter of the polyethylene ring is slightly smaller than the outer diameter of the pulley frame by 0.5-1mm;

[0025] (4) Roughly process the polyethylene ring after digging, and polish the inner surface of the hole of the polyethylene ring;

[0026] (5) Put the roughly processed polyethylene ring material into the oven for heating, and the temperature of the oven is 150°C±5°C;

[0027] (6) Heat the heated polyethylene ring and the pulley frame to obtain a semi-finished product;

[0028] (7) Cool the semi-finished product after the...

Abstract

The invention relates to a preparing method for a diamond wire cutting machine pulley sheet, and belongs to the technical field of wire cutting equipment. The preparing method comprises the followingsteps that firstly, a pulley sheet framework is subjected to washing and oil removing; secondly, a polyethylene bar is cut, and a polyethylene ring is prepared; thirdly, a machine tool is used for conducting hole slotting on the polyethylene ring; fourthly, the polyethylene ring is subjected to rough machining; fifthly, the polyethylene ring is placed in an oven to be heated; sixthly, the polyethylene ring and the pulley sheet framework are subjected to hot shrinkage, and a semi-finished product is obtained; seventhly, the semi-finished product is placed at the room temperature to be naturallycooled; eighthly, the naturally-cooled semi-finished product is subjected to turning; nightly, a slotting tool is used on the numerical control machine tool for slotting the surface of the semi-finished product, and the diamond wire cutting machine pulley sheet is obtained; and tenthly, the diamond wire cutting machine pulley sheet is placed in a warehouse to be stored. By means of the preparingmethod, the wire breakage proportion influenced by a pulley in the cutting process can be effectively reduced, and the pulley cutting service life is prolonged by 20%.

Description

technical field [0001] The invention relates to a method for preparing a pulley sheet of a diamond wire cutting machine, belonging to the technical field of wire cutting equipment. Background technique [0002] Many hard materials in the industry are cut with cutting steel wires or higher-quality gold steel wires, such as polysilicon slices, monocrystalline silicon, and ingots in the photovoltaic field. The diamond wire cutting machine adopts the one-way circulation or reciprocating circulation of the diamond wire, so that the diamond wire and the object to be cut form a relative grinding motion, so as to achieve the purpose of cutting. [0003] Pulleys and pulley pieces are often used in diamond wire cutting machines. During the production of current pulleys and pulley pieces, there are many wire breakages caused by the influence of pulleys on the steel wire take-up and pay-off, and the cutting service life of the main pulley is not long. Contents of the invention [000...
