Cutting off recovery device for linear cutting molybdenum wires

Abstract

The invention discloses a cutting off recovery device for linear cutting molybdenum wires. The recovery device comprises a wire cylinder, guide grooves uniformly distributed on the outer wall of the wire cylinder along the peripheral direction and cut-through axially, cutting off devices respectively disposed on the guide grooves spaced on the outer wall of the wire cylinder along a radial extending direction of the wire cylinder and wire collecting devices disposed in the guide grooves between adjacent cutting off devices; the wire collecting devices and the guide grooves are slidably matched, compressing devices for compressing cutoff electrode wires sleeve the wire collecting devices in the axial direction of the wire cylinder, and tightening devices for driving the cutting off devices and the compressing devices to move radially are symmetrically disposed on the two ends of the wire cylinder. According to the cutting off recovery device, the detaching efficiency of the molybdenum wires is greatly improved, labor intensity of operators is relieved, and the collected molybdenum wires occupy a small space and are orderly collected and convenient to store. The recovery device is simple and compact in structure design, can be mounted on any existing linear cutting machines without a need to modify circuits or other mechanical structures of the existing machines, and is convenient to mount and favorable for wide application.

Description

technical field [0001] The invention belongs to the technical field of electric discharge wire cutting auxiliary equipment, and in particular relates to a wire cutting molybdenum wire cutting recovery device. Background technique [0002] Molybdenum is an important strategic material and an important alloying element in the production of alloy steel, stainless steel, heat-resistant steel and alloy cast iron. Molybdenum is a chemical element. Its chemical symbol is Mo. It is a gray transition metal with a melting point of 2610°C, a boiling point of 5560°C, and a density of 10.2 g / cm3. Molybdenum has high strength, high hardness, and strong corrosion resistance. Small thermal expansion coefficient, good electrical and thermal conductivity and mechanical properties, and can still maintain high strength and high hardness at high temperatures. Molybdenum wire is used in high-temperature electric furnaces, EDM and wire cutting. [0003] During the wire cutting process, the first ...
