Outer cladding workpiece metal outer sleeve laser non-penetration cutting device and method

Abstract

The invention discloses an outer cladding workpiece metal outer sleeve laser non-penetration cutting device and method. The outer cladding workpiece metal outer sleeve laser non-penetration cutting device comprises a laser cutting device, a computer cabinet and an electric control cabinet; the laser cutting device comprises a rack, a cutting unit, a moving unit and a clamping unit, and the cuttingunit, the moving unit and the clamping unit are arranged on the rack; the cutting unit is arranged on the rack in a sliding mode in the X axial direction; a metal sleeve assembly is arranged on the moving unit and can drive the metal sleeve assembly to move in the Y axial direction and the Z axial direction; the clamping unit is used for clamping the metal sleeve assembly and can drive the metalsleeve assembly to rotate in the X axial direction; the metal sleeve assembly is arranged in parallel with the rack; and the electric control cabinet and the laser cutting device are respectively electrically connected with the computer cabinet. According to the outer cladding workpiece metal outer sleeve laser non-penetration cutting device and method, laser automatic cutting can be remotely controlled outside a hot chamber, the fixed focal length cutting of the uneven surface of the metal outer sleeve is allowed, the metal outer sleeve is cut layer by layer, the cutting depth of the laser can be accurately controlled, the surface of the outer cladding workpiece is avoided from being cut and damaged, the cutting efficiency is high, and the environmental pollution is low.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a laser non-penetrating cutting device and method for a metal outer sleeve of an outer cladding workpiece. Background technique [0002] In the field of reactor engineering, it is often necessary to cut the outer sleeve of the outer cladding workpiece in the inspection hot chamber, and then take out the inner outer cladding workpiece. The traditional method is to use a cutting machine to cut the metal outer casing of the outer cladding workpiece in the hot chamber. A large amount of metal particles are produced during the cutting of the metal outer casing by the cutting blade, and the cutting blade needs to be impacted by water flow to cool down. There is waste liquid, and the cutting efficiency is low, and the cutting depth is difficult to control, which will lead to inability to cut efficiently and cause damage to the surface of the removed fuel rod.
