Multiwire cutting equipment and wire mesh tension control mechanism for same

Abstract

The invention discloses multiwire cutting equipment and a wire mesh tension control mechanism for the same. The multiwire cutting equipment comprises a base, a cutting assembly, a first tensioning mechanism and a second tensioning mechanism; the cutting assembly comprises a first cutting roller , a second cutting roller and a third cutting roller which are arranged to be shaped like a triangle; the first tensioning mechanism comprises a first winding drum, a first rotating motor and a first adjusting assembly provided with a first tension transition wheel; the second tensioning mechanism comprises a second winding drum, a second rotating motor and a second adjusting assembly provided with a second tension transition wheel. A cutting wire starts from the first winding drum and is wound around the first adjusting assembly, the first cutting roller, the second cutting roller, the third cutting roller and the second adjusting assembly and then wound on the second winding drum; when cutting is conducted, the first winding drum is matched with the first tension transition wheel, so that it is guaranteed that the cutting wire is in a tension balance state; the second winding drum is matched with the second tension transition wheel, so that it is guaranteed that the cutting wire is in the tension balance state.

Description

technical field [0001] The invention relates to multi-wire cutting technology, in particular to a multi-wire cutting device and a wire mesh tension control mechanism for the device. Background technique [0002] Wire cutting technology is a relatively advanced square extraction processing technology in the world at present. Its principle is to rub the workpiece (such as silicon rod, sapphire, or other semiconductor hard and brittle materials) through high-speed moving gold steel wire, and cut out the square. Ingot, so as to achieve the purpose of cutting. During the cutting process of the workpiece, the gold steel wire is guided by the guide wheel to form a wire net on the main wire roller, and the workpiece to be processed is fed by the rise and fall of the worktable. Under the action of the pressure pump, The cooling water automatic spraying device installed on the equipment sprays the cooling water to the cutting part of the steel wire and the workpiece, and the cutting ...
