Air curtain powder capturing type metal surface wire drawing treatment process

Abstract

The invention discloses an air curtain powder catching type metal surface wire drawing treatment process, and belongs to the field of metal wire drawing. According to the air curtain powder catching type metal surface wire drawing treatment process, a circumferential dust catching ring is arranged outside metal, so that an air curtain can be formed around a metal plate during wire drawing, on one hand, the air curtain can effectively adsorb metal powder, the metal powder is moved toward a dust catching ring body and adhered or collected, compared with the prior art, the situation that the metal powder flies is remarkably reduced, potential safety hazards are effectively avoided, in the dust adsorption process, an air containing hollow ball expands to extrude an inner pressure semi-ring, the air position in the inner pressure semi-ring is transferred, then extrusion force is generated on powder sticking pieces, lubricating oil inside the inner pressure semi-ring overflows, the adhesive force to the metal powder is remarkably improved, the metal powder adheres to one another, the particle size is increased, the metal powder gradually falls off under the action of gravity, and therefore, the situation that the metal powder which is not collected is diffused into air again is effectively avoided.

Description

technical field [0001] The invention relates to the field of metal wire drawing, and more specifically, relates to an air curtain powder trapping metal surface wire drawing treatment process. Background technique [0002] Metal wire drawing is a manufacturing process in which the metal plate is repeatedly scraped out with sandpaper. The main process of the process is divided into three parts: deesterification, sand mill, and water washing. [0003] In the wire drawing process, the special film technology after anodizing can make the metal surface generate a film layer containing the metal component, clearly showing every tiny silk trace, so that fine hair strands appear in the metal matte luster. More and more metal shells of products use metal wire drawing process to play the role of beauty and corrosion resistance. Make the product have both fashion and technology elements. Metal surface brushing can well cover up mechanical lines and mold clamping defects in production...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the object of the present invention is to provide an air-curtain powder-collecting type metal surface wire drawing treatment process, which, through the circumferential dust-collecting ring arranged outside the metal, can wrap around the metal plate during wire drawing. Forming an air curtain, on the one hand, the air curtain can effectively absorb metal powder, so that the metal powder moves toward the dust collection ring and is adhered or collected. Compared with the existing technology, the occurrence of flying metal powder is significantly reduced, effectively avoiding safety hazards. Hidden danger, during the process of dust adsorption, the air-contained hollow ball expands and squeezes the internal pressure half-ring, so that the position of the air in the internal pressure half-ring is shifted, and then exerts a squeezing force on the sticky powder sheet, causing the internal lubricating oil to overflow. Significantly improve the adhesion to the metal powder, the metal powder sticks to each other, the particle size becomes larger, and gradually falls off under the action of gravity, thus effectively avoiding the situation that the uncollected metal powder diffuses into the air again
