Wiring structure of three-roller diamond wire multi-wire cutting machine

Abstract

The invention relates to a routing structure of a three-roller diamond wire multi-wire cutting machine, and belongs to the technical field of diamond wire cutting, conductive rollers are obliquely arranged in a plane, the routing direction of diamond wires is ensured to be matched with transition wire grooves in the surfaces of the conductive rollers, and diamond wires are wound between the conductive rollers and two cutting rollers back and forth to form a wire net. The parallel wire net is located between the two cutting rollers and is perpendicular to the axes of the cutting rollers, the transition wire net is located below the two cutting rollers, the projection of the transition wire net on the horizontal plane is parallel to the transition wire groove, and the parallel wire net is used for cutting workpieces. Therefore, the cutting quality is improved, and the consistency of the cutting quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of diamond wire cutting, and in particular relates to a wire routing structure of a three-roller diamond wire multi-wire cutting machine.

Problems solved by technology

The application number is CN201910969518.9, and the name is diamond multi-wire electric spark discharge cutting method and wire cutting device. The wire wheel, tension wheel and guide wheel are wound to two processing rollers, then passed through the guide wheel, tension wheel and wire-discharging wheel, and finally wound to the take-up and pay-off wheel, and its description of the wire structure (ie wire mesh structure) not detailed enough

At the same time, the structure of the wire mesh using the multi-wire cutting method is relatively complicated, and the stability of the wire mesh tension is not easy to control. In particular, the feed roller increases the possibility of jumping wires and oblique pulls, resulting in diamond particles easily detaching from the diamond wire or even breaking the wire. , affecting cutting efficiency and cutting quality
