Embodiment 1

[0028] Embodiment 1: A copper full-needle pen head 1 (see accompanying drawing 1 accompanying drawing 2), adopts lead brass coppery cylindrical material to make, the middle is ink hole, the end is provided with a round hole concave cavity 3, round Balls 4 are embedded in the concave cavity of the hole, and the end of the concave cavity of the circular hole is a closure 5, which fixes the ball. The inner wall forms the bottom of the concave cavity of the round hole, and there is a gap between the inner walls of each concave point. The bottom of the concave cavity of the round hole is spherical, and a part of the spherical surface is on the inner wall of the concave point. The processing technology of the full needle tube pen tip includes the following step:

[0029] 1.1 Select a copper cylinder with a diameter of 0.8mm to cut it off, and cut it into a needle tube with a length of 8mm;

[0030] 1.2 Clamp the cut copper cylinder on the machine tool, and drill the copper cylinder...

Embodiment 2

[0039] Embodiment 2: a kind of full needle tube nib (see attached image 3 attached Figure 4 ), made of copper cylindrical material, with an ink hole in the middle, a round hole cavity 3 at the end, a ball 4 embedded in the hole cavity, and the end of the hole cavity is a closing 5 to fix the ball , the bottom of the round hole cavity of the full-needle pen head is a closed part 6 with a small hole 7 in the middle, the bottom of the round hole cavity is spherical, and five grooves 10 communicated with the middle small hole are punched out on the spherical surface. The processing technology of the full-needle pen tip comprises the following steps:

[0040] 1.1 Select a copper cylinder with a diameter of 0.8mm to cut it off, and cut it into a needle tube with a length of 8mm;

[0041] 1.2 Clamp the cut copper cylinder on the machine tool, and drill the copper cylinder with a drill 8 with a diameter of 0.5mm and a section 9. When drilling, the copper cylinder rotates at a high ...

Abstract

The invention relates to a copper pen head with full needle tube and the processing technique thereof, solving the disadvantage in the prior art that stainless steel is used to make pen head, which increases the material cost and leads to difficult processing. The processing steps is as follows: 1.1 selecting a copper cylinder and cutting the cylinder into a length of the pen head; 1.2 clamping the cut copper cylinder firmly on a lathe and drilling hole on the cylinder by a drill needle with appropriate diameter and profile. 1.3 processing an internal treatment at one end of the copper cylinder and producing a hole concave cavity for placing a rolling ball; 1.4 putting the rolling ball into the processed hole concave cavity and fixing the rolling ball by closing the hole . Adopting the copper cylinder as the pen head can save material cost, the cost can be saved by 30% comparing with the stainless steel pen head; the hardness of copper is lower than that of stainless steel, and can suffice the writing requirements; the processing of copper is easier than processing of stainless steel; and the processing cost is reduced and the processing efficiency is increased.

Description

technical field [0001] The invention relates to a nib and its processing technology, in particular to a copper all-needle nib and its processing technology. Background technique [0002] Due to the advantages of the gel pen and the fountain pen and the ballpoint pen, the writing is smooth, so it is quite popular. Now the refills of gel pens on the market mostly use stainless steel nibs, balls and plastic pen tubes. There are many types of stainless steel nibs, especially when the pen nibs are small in size and the diameter of the ball is about 0.5mm, needle tube nibs are generally used. . For example, the announcement number of the announcement on July 26, 2006 is the patent of CN2799263Y, which is called a full-needle neutral nib. This patent is a needle-type nib. As a result, stainless steel is used, and the material cost and processing cost are relatively high. Contents of the invention [0003] The present invention solves the shortcomings of using stainless steel a...
