A diamond wire multi-wire slicer

Abstract

A multi-wire slicer employing diamond wires, consisting of a wire mesh (2) for cutting, guide wheels, wire wheels (6), a cutting head, and a cooling system. Diamond wires (7) leading out from two ends of the wire mesh respectively pass over a first guide wheel (3) and a second guide wheel (4) and are connected to the two wire wheels. Upon passing over the first guide wheel, the direction of the diamond wire leading out from the wire mesh becomes perpendicular to the original leading-out direction thereof. After passing over the second guide wheel, the diamond wire is arranged in a direction parallel to the direction thereof before passing over the second guide wheel. The diamond wire passing over the second guide wheel is wound around the wire wheel. The two wire wheels rotate to drive the diamond wires and wire mesh to move, thereby performing a cutting operation. The wire mesh is wound around outer sides of two main rollers (1). The two wire wheels are arranged perpendicularly to the main rollers in the wire mesh. In the slicer, the wire wheels are rotated 90 degrees so as to be perpendicular to the main rollers, thus reducing tension loss of the system by 1 / 3. In addition, the direction of a wire arrangement error and the direction of tension adjustment are orthogonal and independent, thus realizing decoupling. In addition, the present invention enables highly efficient cooling by employing a oscillating cooling mechanism.

Description

technical field [0001] The invention relates to an industrial cutting device, in particular to a diamond wire multi-wire slicing machine. Background technique [0002] Diamond wire multi-wire slicer is a powerful equipment for cutting brittle and hard materials at present. It is composed of cutting wire net, guide wheel, take-up / pay-off wheel, cutting head and cooling system. The key of the cutting is the grinding and cutting of the workpiece by the high-speed reciprocating motion of the wire mesh. Such as figure 1 As shown, the existing diamond wire multi-wire slicing machine in the market realizes the high-speed movement of the wire mesh by the main roller wire mesh, the No. 1 guide wheel, the No. 2 guide wheel, the No. 3 guide wheel and the wire wheel. [0003] Let the cutting setting tension be T0, the wire mesh tension be T, and the steel wire breaking tension be Tb. The tangential force required by the guide wheel from 0 to the highest wire speed is F; [0004] Then...

Problems solved by technology

[0011] Therefore, the occupied / loss tension of the system itself is 3F, and these forces cannot participate in the cutting wire network. If the cutting tension setting plus 3F is greater than the breaking tension of the steel wire: T0+3F>Tb; then when the steel wire accelerates and decelerates during cutting, The steel wire is bound to break

The loss caused by wire breakage is the largest for multi-wire slicers

[0012] The role of the three guide wheels makes the tension of the diamond wire too large, resulting in excessive power loss of the system, and may even cause the diamond wire to break due to excessive tension, resulting in greater losses

[0019] Then, when the error source cannot be distinguished, fuzzy control is generally used, and dead zone control is added to reduce system sensitivity.
