Brush manufacturing method and brush manufactured thereby

Abstract

Flanges, outer cups and inner cups with innovative embodiments can also be made with the same molding process, improving the characteristics of the traditional brushes.

Description

technical field [0001] The invention relates to a brush tool manufacturing method and the brush tool manufactured by the method. The present invention is applicable to the field of industrial and / or hobby brushes, that is, brushes that can be used for machining procedures (eg, deburring surfaces, cleaning solder joints, etc.) for industrial or personal use. Background technique [0002] In the conventional brush manufacturing process, the components used to form the brush are generally assembled using a thread restricting device. [0003] These components are the flange, wire loop, and constriction for round brushes, and the inner cup, wire loop, outer cup, and constriction for cup brushes. [0004] In a conventional method, the circular portion of the constriction device is first perforated through the center of the various parts used to form the brush, which are formed by cold compression molding. [0005] The next step is to pull out the edge of the extending portion of...

Problems solved by technology

[0035] This can lead to breakage of the metal wire, which makes the resulting brush easy to disintegrate, since the fastening effect created by the plastic mold is quickly destroyed at high temperatures:

[0036] Plastics cannot be used in brushes with special metal components such as stainless steel or non-sparking materials, because they would contaminate the surface, or because of the potential for extreme interactions between the plastic material and the various metal parts that make up the brush. Risk of electric discharge (spark) due to potential difference;

[0037] The different materials in the composition (plastic, steel, paint, etc.) make the recycling of the resulting brushes cumbersome and expensive
