Take-up and pay-off device for wire cutting machine tool

Abstract

The invention discloses a take-up and pay-off device for a wire cutting machine tool. The take-up and pay-off device comprises a framework. A wire arranging mechanism is mounted on the framework and comprises a guide wheel, a wire arranging motor and a wire arranging lead screw, the wire arranging lead screw is driven by the wire arranging motor, a wire wheel base plate is further arranged on the framework, a wire wheel motor and a wire wheel are mounted on the wire wheel base plate, and the wire wheel comprises a pay-off area and a take-up area. The take-up and pay-off device has the advantages that the take-up and pay-off device is simple in structure, high in wire storage capacity and control precision and easy to control; a take-up function and a pay-off function are integrated on the same wire wheel by a method for dividing the wire wheel into the two independent areas, a plurality of layers of wires can be arranged in both the take-up area and the pay-off area on the same wire wheel, and as the wire arranging mechanism is provided with the independent motor, the distances among the cutting wires wound on the wire wheel can be optionally controlled by the aid of the take-up and pay-off device which is of a structure with the single wire wheel.

Description

technical field [0001] The invention relates to a compound control technology for wire take-up and release for wire cutting, in particular to a technology for wire-cutting machine tools in which wire take-up and wire release are independently but synchronously controlled. Background technique [0002] The take-up and pay-off control technology is one of the key technologies of wire cutting machine tools. At present, there are two main types of take-up and pay-off control technologies used in wire cutting machine tools in the world: one is that the take-up wheel and the pay-off wheel are respectively placed on the two sides of the machine tool. On the side, the two wire wheels use independent rotating motors and wire-discharging motors; one is to use the same wire wheel for take-up and pay-off, and take-up and take-up at the same time as pay-off. The disadvantage of the first control technology is that since the take-up wheel and the pay-off wheel are completely independent, ...

Problems solved by technology

The disadvantage of the first control technology is that since the take-up wheel and the pay-off wheel are completely independent, it is difficult to ensure the synchronization of the two wheels during control, which will cause frequent changes in the tension of the cutting line and affect the processing accuracy; the second control technology The disadvantage is that because the take-up and take-up line adopts the same wheel, the cutting line can only be arranged in a single layer, and the wire storage is short, which leads to the frequent reversing of the cutting wire during processing, which affects the processing accuracy and processing efficiency.
