Problems solved by technology
[0003] Existing water-based pens generally have a single structure and are made of free-cutting steel, which requires relatively high processing precision, high cost, and relatively large material consumption. At the same time, the steel ball of the existing water-based pen seals the ink. Poor performance and easy to leak water. To solve these problems, we propose a nib processing method for water-based pens.

The invention discloses a processing method for a pen tip of a rollerball pen. The method comprises the following steps that S1, a cylindrical plastic strip A and a plastic strip B are obtained through injection molding separately, a blank A is obtained by cutting from the plastic strip A by a specified length, a frustum is obtained by turning from one end of the blank A externally, a first through hole and a second through hole are sequentially drilled from the other end of the blank A, the second through hole is a tapered hole, and a shell is obtained; and a blank B is obtained by cutting from the plastic strip B by a specified length, a shoulder is obtained by turning from the outer portion of the blank B, then a reducing neck is obtained by turning from one end of the blank B, finally,a third through hole is drilled from one end of the blank B, and an inner shell is obtained. The processing method is convenient in processing, low in manufacturing cost and capable of saving materials, and has good protection effect on ink.
Description
technical field [0001] The invention relates to the technical field of nib processing, in particular to a method for processing a nib of a water-based pen. Background technique [0002] The water-based pen is mainly characterized by a ball-point pen tip and an ink-free refill. Because of its convenient use, cleanliness and fluent writing, after decades of development, it has become popular in large and small institutions, companies and colleges and universities. colleges. [0003] Existing water-based pens generally have a single structure and are made of free-cutting steel, which requires relatively high processing precision, high cost, and relatively large material consumption. At the same time, the steel ball of the existing water-based pen seals the ink. Poor performance, easy to leak, we propose a water-based pen nib processing method for these problems. Contents of the invention [0004] The object of the present invention is to propose a nib processing method for ...
