Mounting method of multi-station wire-electrode cutting molybdenum wire

Abstract

The invention discloses a mounting method of a multi-station wire-electrode cutting molybdenum wire. Four guide wheels and a tensioning mechanism are introduced. The mounting method comprises the following steps of bypassing the second guide wheel by the molybdenum wire pulled from a wire storage drum after being guiding the molybdenum wire horizontally by the first guide wheel; converting, by thesecond guide wheel, the trend of the molybdenum wire from a horizontal direction into a vertical direction; bypassing the third guide wheel by the molybdenum wire pulled from the second guide wheel;converting, by the third guide wheel, the trend of the molybdenum wire from the vertical direction into the horizontal direction; bypassing the fourth guide wheel by the molybdenum wire pulled from the third guide wheel; converting, by the fourth guide wheel, the trend of the molybdenum wire from horizontal direction into an inclined direction; returning the molybdenum wire pulled from the fourthguide wheel to the wire storage drum through a tensioning wheel in the tensioning mechanism; and forming a plurality of stations distributed in the vertical direction between the second guide wheel and the third guide wheel. The mounting method has the advantages that the cost is low, the noneffective molybdenum wire is relatively short, and the occupied plane space of the whole machine is small.

Description

technical field [0001] The invention relates to a wire electric discharge cutting technology, in particular to a method for installing molybdenum wire for multi-station wire cutting. Background technique [0002] Wire EDM, referred to as wire cutting, is developed on the basis of EDM perforation and forming. It not only makes the application of EDM develop, but also replaces EDM perforation and forming in some aspects. [0003] The wire electric discharge cutting technology uses the electric discharge between the molybdenum wire and the workpiece to realize the cutting process. In order to solve the discharge and cooling after cutting, the molybdenum wire adopts reciprocating motion, which is fast wire cutting. The wire-feeding speed of fast-feeding WEDM machine tools is 6-12mm / s, and the demand for fast-feeding WEDM machine tools reaches more than 200,000 units per year. They are widely used in various types of low-end mold manufacturing and special parts processing. It ha...

The installation structure of this molybdenum wire, the 3rd guide wheel 13 and the 4th guide wheel 14 are on the same vertical line, the 5th guide wheel 15 and the 6th guide wheel 16 are also on the same vertical line, form two The station can perform wire cutting processing on two workpieces at the same time, but it needs to use 7 guide wheels, which is costly; the length of invalid molybdenum wire is long, and the effective utilization rate of molybdenum wire is low; because the two stations are horizontally distributed Therefore, the plane space occupied by the whole machine is relatively large, and the installation of the workpiece is troublesome
