A kind of processing technology of pen cap

Abstract

A kind of processing technology of pen cap provided by the present invention comprises the following steps: S1 material preparation: prepare shrapnel, convex hull, pen cap; S2 welding: use spot welder to weld shrapnel on the pen cap, and weld convex hull to shrapnel above, to obtain the semi-finished pen cap; S3 polishing: polish the semi-finished pen cap, and grind away the solder raised at the welding position; S4 sandblasting: use a sandblasting machine to sandblast the semi-finished pen cap to make the surface of the semi-finished pen cap rough; S5 PVD: in The surface of the pen cap semi-finished product is sprayed with a layer of anti-fingerprint oil to make the pen cap; wherein, the hardness of the pen cap is less than that of the shrapnel, and the hardness of the convex shell is less than the hardness of the shrapnel. The processing technology of the pen cap provided by the present invention is to manufacture the pen cap through welding, polishing, spraying and PVD. The prepared pen cap can meet the hardness requirement of the pen cap and the elasticity requirement of the shrapnel, and the process is simple and the processing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pen cap processing, in particular to a processing technology for a pen cap. Background technique [0002] Pen caps, commonly known as pen caps, are also known as pen caps, which refer to protective devices for protecting pencil points or ink evaporation in water-based pens and oil-based pens, and have the functions of decoration and portability. Pen caps are divided into plastic caps and alloy caps according to their materials. Ordinary pen caps generally have the following structures, including shrapnel, convex hull, and cap. For alloy caps, they are generally prepared by integrated casting molding technology, but the material of each part of the integrally formed alloy cap can only be the same. However, with the continuous improvement of the requirements of the stationery industry, the shrapnel requires sufficient hardness and good elastic effect, so that the pen cap can have a certain clamping force a...
