Problems solved by technology

During processing, the molten pool is affected by the surface state of the substrate and parameter fluctuations, and its position, size, and shape will change unexpectedly; the wire is affected by curvature changes, resistance fluctuations, and thermal bending, and the wire end will swing randomly. In most cases, it is within the range of the molten pool and can still be processed, but occasional large swings may cause the wire to deviate from the molten pool, thereby interfering with the workpiece. silk system

Abstract

The invention discloses a wire aligning method and device used in metal wire melting processing. The invention is aimed at the technology of melting metal wires through a heat source to process the metal wires. A camera equipped with a filter device is used to take a picture of a molten pool and a picture of the surroundings, and the pictures are processed and defined so as to distinguish the outline of the molten pool and the image of a wire end. According to processing characteristics and the practical experiences, the molten pool is divided into a safe area, a transition area and an unsafe area. The relative positions of the wire end and the molten pool are compared; when the wire end is located in the unsafe area outside the transition area or is located in the transition area for a long time, a computer sends out a feedback signal according to the relative positions of the wire end and the center of the molten pool to control an motor of an adjusting mechanism to move; and the wire end is adjusted to the safe area through the movement of a wire feed pilot mouth. In such a way, self-adaptive alignment of a wire is realized, the wire feeding process is smoother and the appearance quality of the molded wire is better.

Description

technical field [0001] The invention relates to a wire alignment method and device for metal wire melting processing, belongs to the technical field of special processing, and is suitable for high-energy beam or arc filling wire welding, cladding or rapid prototyping. Background technique [0002] High energy beam or arc melting wire processing technology is mainly used for welding, cladding and rapid prototyping. In order to ensure the stability of the processing project, the shape of the processed surface and the internal quality, when the heat source melts and feeds the wire and fills it, the alignment accuracy of the wire is required to be very high. [0003] The stability of the wire melting process depends on two aspects: [0004] 1. Stable feeding and precise alignment of wire; the wire feeding system consists of three parts: wire storage device, feeding device, and alignment device. The wire storage device includes the silk storage fiber and its support; the feedin...
