Rod for fishing rod and its making process

Abstract

The making process of rod body for fishing rod includes winding one polymer material layer without superposing outside one compound material layer; spraying one extinction material layer to the surface of the polymer material layer; winding one layer of combining material of smelting point lower than that of the polymer material layer with partial superposing to the extinction material layer; sintering to form rod body core in complex layered structure; removing the rod body core from one mandrel and peeling off the combining material layer to form the rod body for fishing rod.

Description

technical field [0001] The invention relates to a rod body for fishing, in particular to a rod body of a fishing rod and a manufacturing method thereof. Background technique [0002] Based on the convenience of carrying and storage, the fishing rod will be set in a multi-section hollow shape with a tapered pipe diameter, and can be divided into "vibration type" and "vibration type" according to whether the rod body is drawn out sequentially or connected segment by segment. Concurrent style" two categories. [0003] The current rod body method of fishing rods, such as figure 1 , 2 As shown in , 3, it is mainly to make the reinforced gray cloth 91 made by impregnating the reinforced fiber material (carbon fiber or glass fiber) with synthetic resin. Figure 6 Process 901 to process 907, and wound on a cylindrical mandrel 92 with a thinner front end (process 901), and then, an OPP (biaxially stretched polypropylene) tape 93 is spirally and partially overlapped The form is wo...

Problems solved by technology

[0004] refer to figure 2 , 3 , 4, but before the sintering of this rod body, its surface layer will produce a step-like recessed space 94 in its overlapping part after being wound by OPP tape 93, so when the reinforced gray cloth 91 and OPP tape When 93 is sintered, the OPP tape 93 will not only form a radial constriction force on the reinforced gray cloth 91 due to the heat shrinkage of its own material, but also the fiber material in the reinforced gray cloth 91 will also follow the flow of synthetic resin. And enter in this concave part space 94, so, refer to Figure 5 After sintering, the surface of the sintered rod blank 9 will produce a plurality of ring-shaped raised parts 95, and these raised parts 95 have a considerable difference in height and size, so that the surface of the rod body is prone to scratches and bruises, and After tearing off the OPP tape 93, the outer surface of the rod body wil
