Ball-point pen

Abstract

The invention discloses a ball-point pen of adopting a glass bead (the diameter is greater than 0.8 mm) as a pen point ball. The glass bead meeting the requirements (including diameter range, perfect circle, surface smoothness, hollow or solid state and the like) is obtained by strictly screening the produced glass beads. The glass bead is used for replacing an original steel ball to serve as the pen point ball for producing and processing the ball-point pen.

Description

technical field [0001] The invention relates to a novel ball-point pen, in particular to a ball-point pen with a new material for the nib ball. Background technique [0002] The ball point of a ballpoint pen refers to the "ball" on the tip of the ballpoint pen. The tip is the key of the ballpoint pen, and the tip is divided into a ball on the tip and a ball seat. At present, the production of ballpoint pen balls has high requirements on processing precision and material selection. Tungsten carbide balls are the most widely used at home and abroad. my country already has a good foundation, which can not only meet domestic production needs, but also Export in large quantities. Foreign production equipment has relatively higher requirements on raw materials, and domestic stainless steel wire rods cannot be used, and Japan must rely on imported free-cutting stainless steel wire rods. [0003] Glass beads refer to solid or hollow spherical beads with silicate as the main compone...

Problems solved by technology

[0004] In order to solve the problems of difficult processing and high raw material requirements of existing ball-point pen balls, and to further expand the application range of ball-point pens, the present invention provides a technical solution that uses glass beads (above 0.8 mm in diameter) to replace the existing "steel balls", thereby Reduce the difficulty of production and processing of ballpoint pen balls and the high requirements for raw material selection
