Abstract

The invention discloses a device and a method for measuring tension of a wire mesh of a multi-wire cutting machine. The tension is an important parameter in the process that the multi-wire cutting machine machines a crystal ingot, and the tension of the wire mesh is changing and is difficult to measure by an ordinary tension detection tool. According to the measuring principle of the measuring device, the tension of wires is calculated on the basis that the force of the measured wires is balanced in the vertical direction and the measurable gravity is equivalent to the pressure applied by the crystal ingot on the measured wires; and the device comprises measuring stand columns, a T-shaped connecting rod, a pressure sensor, connecting wires, a long box, a counterweight liquid, a multi-meter and the crystal ingot with a conductive sheet sandwiched. The tension of the wires in different positions is measured, and the distribution condition of the tension of the wire mesh can be obtained. With the device and the method, the tension of the wire mesh in the cutting process is measured, and the scientific basis is provided for technological adjustment.

Description

technical field [0001] The invention relates to a wire mesh tension measuring device and method for a multi-wire cutting machine, which is used for measuring the tension of the wire mesh during the slicing process of the multi-wire cutting machine, and belongs to the field of multi-wire cutting processing. Background technique [0002] Multi-wire cutting machine is a high-efficiency and high-precision hard and brittle material slicing processing equipment, referred to as wire saw. According to the different ways of abrasives, it can be divided into two types: free abrasive multi-wire cutting and bonded diamond multi-wire cutting. The cutting principle of free abrasive multi-wire cutting is to wind the steel wire on the grooves of multiple guide wheels to form a wire net. Abrasive mortar is sprayed onto the wire mesh, and the moving wire mesh carries the mortar into the workpiece to be cut, thereby cutting the workpiece into hundreds or thousands of thin slices. The princip...
