Abstract

The invention discloses a device of reducing deformation of a thin-wall tubular part in a laser cladding process, and belongs to the technical field of mechanical equipment. The device comprises a spiral column, wherein a first helix and a second helix are arranged on the two sides of the center of the spiral column; the first helix and the second helix are opposite in direction and are spliced inthe center of the spiral column; the first helix and the second screw-mount of the spiral column are is in screwed connection with symmetrical regular polygon wedge blocks; fan-shaped blocks are arranged at corners of the two regular polygon wedge blocks in the same vertical direction; grooves fit with the angles of the regular polygon wedge blocks in the same vertical direction are formed in thefan-shaped blocks; and gaps are arranged between the adjacent fan-shaped blocks. The device cannot be stuck in an internal wall due to external wall shrinkage and is convenient to mount and dismount.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a device for reducing deformation of thin-walled tubular parts during laser cladding. Background technique [0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It forms a metallurgical cladding layer on the surface of the base layer by adding cladding materials on the surface of the base material and using a high-energy-density laser beam to fuse it together with the thin layer on the surface of the base material. In the process of laser cladding the outer surface of thin-walled tubular parts, the parts will shrink and deform when heated. [0003] In the existing laser cladding process of the outer surface of thin-walled tubular parts, the anti-deformation tool is first installed in the tubular part, that is, by applying pre-pressure to the tubular part in advance, the heating time of the tubular part can...
