Abstract

The invention provides a bullet-shaped pen point and a machining technology thereof. The problems that the existing machining technology for bullet-shaped pen points is complex, materials are wasted and the manufacturing cost is high are solved. The bullet-shaped pen point is characterized by comprising a metal hollow tube, a solid bar and a bead in a combined manner. Compared with the original technology for machining the bullet-shaped pen point by using a metal hollow rod directly, the machining technology of the bullet-shaped pen point has the advantages that the technology is simplified, and the production efficiency is improved. Moreover, waste on materials can be reduced, and the production and machining cost is reduced.

Description

technical field [0001] The invention relates to a gel pen, in particular to a bullet-shaped pen tip and its processing technology. Background technique [0002] Bullet type nib, its traditional production method is to form through multi-channel program processing with a solid stainless steel material. Specifically, after the bottom of the solid material is chamfered, the center hole is drilled from the inside, and after 11 high-speed cutting holes, the ink channel and the outer circle after cutting are completed. The front end is cut at a high speed to form 30°, the ball seat hole is cut and small holes are drilled at the top of the 30°, the ink channel at the back end is opened, and finally the ball is inserted into the ball seat hole. [0003] In addition, the Chinese invention patent application (application publication number: CN 104097034 A, application publication date: 2014.10.15) also discloses a nib processing method, through multiple processes such as radial cold ...
