Method for manufacturing double-structure rod

Abstract

The invention provides a rod manufacturing method for manufacturing various rods such as a ski pole, an alpenstock, a golf club and a fishing pole in an original silk weaving mode so as to improve the light-weight trend and the durability of a product, and relates to a method for manufacturing a double-structure rod. The method for manufacturing the double-structure rod comprises the following steps: forming a structure, namely, synthesizing inner-side original silk and outer-side original silk in a weaving mode so as to form a fiber structure; performing resin immersion, namely, immersing the fiber structure into resin; curing resin, namely, heating the fiber structure which is immersed in the resin in a relatively low temperature environment so as to cure the resin; and removing the core, namely, separating a core shaft. By adopting the method, rods can be easily manufactured, the raw materials are saved, the manufacturing cost is lowered, the durability of the rods are improved, the light-weight trend is achieved, the preservation property of the raw materials is also improved, the formation design can be diverse, the manufacturing environment can be relatively clean, the production efficiency is improved, and large-scale volume production is achieved.

Description

technical field [0001] The present invention is a method for manufacturing a pole with a double structure, specifically a method that can be widely used in the manufacture of poles such as ski poles, golf clubs, trekking poles, and fishing poles. A method for manufacturing a double-structured rod with a double-structured manufacturing method and an external raw wire, which optimizes the internal structure and facilitates the manufacturing process. Background technique [0002] In general, techniques for manufacturing various rods in hollow form for ski poles, golf clubs, trekking poles, fishing rods, etc. have been disclosed in the following patents, such as Korean Laid-Open Patent No. 366 of 1995 (January 3, 1995 Publication) and Publication Patent No. 3006 in 2003 (published on January 9, 2003), a prepreg pressed with reinforcing fiber and resin, a mandrel, and a core material are staggered and bonded or spirally bonded. Made and then fired. As disclosed in Laid-open Pa...

AI Technical Summary

Problems solved by technology

In addition, scraps are produced during cutting, resulting in serious waste of materials, and the overlapping parts of the prepregs will appear raised during cooling, making the appearance not smooth, thus causing problems such as increased overall cost and reduced appearance.

[0004] If the previous method of manufacturing rods is combined with Laid-Open Patent No. 65867 in 1997, the technology of dipping fiber strips (precursor filaments) into resin and then bonding them, but if you want two layers bonded in two different directions If it is a separate double layer, because the bonding step must be performed twice, two bonding equipment with different bonding directions are required, so there are problems such as long operation time and complicated operation steps
