Molybdenum-wire three-guide-wheel tensioning system

Abstract

The invention discloses a molybdenum-wire three-guide-wheel tensioning system, comprising a force measuring part and a transmission part, wherein the force measuring part comprises a base, a guide wheel I, a guide wheel II, a transition plate, a force measuring sensor and the like; the transmission part comprises a bottom plate, a stepping motor, a coupler, a coupling seat, guide columns, screws, a linear bearing, a thread block, a moving seat, a guide wheel III and the like; the guide wheels are made into one-edge guide wheel; the bottom plate of the force measuring part is fixed on the inclined plane of the base of the transmission part by the screws and positioning pins; and a molybdenum wire passes from the upper side of the guide wheel I, then bypasses the lower side of the guide wheel II and finally moves downwards after passing through the upper side of the guide wheel III to form the molybdenum-wire three-guide-wheel tensioning system. The molybdenum-wire three-guide-wheel tensioning system disclosed by the invention has the advantages that not only is the sensitivity improved, but also the problem of inconvenient wire penetration of the existing guide wheel is made up.

Description

technical field [0001] The invention relates to a component of a wire cutting machine tool, in particular to a tensioning device for a molybdenum wire of the wire cutting machine tool. Background technique [0002] Most of the existing molybdenum wire tensioning systems for wire cutting are composed of four double-supported guide wheels. The setting of four guide wheels will affect the tensioning sensitivity of molybdenum wire, which is one of the reasons for the rough processing of fast wire cutting. The two ends of the double-supported guide wheel are provided with guide wheel seats and bearings. When replacing the molybdenum wire, since the guide wheel is located in the middle of the two guide wheel seats, when threading the molybdenum wire, the molybdenum wire has to pass through the middle to replace it. It seems troublesome. Contents of the invention [0003] In order to make up for the above-mentioned deficiencies of the molybdenum wire tensioning system, the prese...
