Abstract

The invention provides a constant-tension wire feeding device for a one-way low-speed wire feeding wire cut machining tool. In the process of low-speed wire feeding wire cut machining, whether the tension of an electrode wire is constant is an important factor influencing machining quality, because in the process of movement of the electrode wire, unstable electrode wire tension will bring difficulties to the selection of technological parameters of machining and influence machining quality. The constant-tension wire feeding device for a one-way low-speed wire feeding wire cut machining unit comprises a wire conveying system and a tension control system, wherein the wire conveying system consists of a winding wheel, a vibration reduction wheel, an auxiliary wheel and a wire release wheel, and the tension control system mainly consists of a tension wheel and a guide rail component. The constant-tension wire feeding device skillfully employs the characteristics that the shaking of wires is little in a low-speed wire feeding state, realizes constant tension by means of the self-gravity of the tension wheel, and is of greater practical importance for improving the machining quality and machining efficiency of low-speed wire feeding wire cut machining.

Description

technical field [0001] The invention relates to a constant-tension wire-feeding device for slow-speed wire-cutting, which is used to create a slow-speed wire-feeding environment with stable tension. In particular, it is used in the wire-feeding environment of small wire-cutting machine tools, and belongs to the field of electrical processing. Background technique [0002] Some complex and irregular hole and outer contour processing, as well as hard material processing, are difficult to complete with conventional machine tools, and need to be processed by wire electric discharge cutting. Slow-speed WEDM has great advantages in processing irregular contours and hard materials. The principle of slow-speed wire cutting is to use the moving thin wire as the working electrode, and pass a pulse current between the wire and the workpiece, and use the electric erosion effect of the pulse discharge between the two electrodes to cut the workpiece. The tool electrode used is a very th...
