Problems solved by technology

However, due to the small wall thickness of the silicone membrane tube, under the action of wind pressure, the membrane tube is easy to break, causing air leakage, and the proportion of defects is relatively high; at the same time, the product is prone to inward folding and internal breakage and other undesirable phenomena.

Embodiment 1

[0027] A method for forming an integrated rod by filling air described in this embodiment specifically includes the following steps:

[0028] (1) Prepare a thickened silicone tube, one end of the thickened silicone tube is closed, and the wall thickness of the thickened silicone tube is 2mm;

[0029] (2) Select a profiling tool with the same shape as the thickened silicone tube, put a nylon membrane tube on the outer jacket of the profiling tool, close one end of the nylon membrane tube, and extract the air between the nylon membrane tube and the profiling tool to make the Nylon film tube is attached to the imitation tool;

[0030] (3) Wrap several layers of sheet-like carbon fiber yarns or glass fiber yarns with sticky resin on the profiling tool wrapped with nylon film tubes;

[0031] (4) Pull out the profiling tool to obtain a straight rod preform;

[0032] (5) Insert the thickened silicone tube into the nylon membrane tube inside the straight rod preform, and connect the...

Abstract

The invention relates to the technical field of processing of sports goods, in particular to an integral rod wind filling formation method which concretely comprises the following steps of (1) preparing a thickened silicone tube; (2) selecting a profiling product; (3) wrapping yarns; (4) preparing a straight rod preform; (5) preparing an integral rod preform; (6) performing butt jointing on steeltuyeres; (7) performing formation; and (8) obtaining an integral rod coarse blank. By adopting the integral rod wind filling formation method provided by the invention, the supporting force of silicone is kept, so that the wall thickness of a product is uniform, interlayer bonding is good, and poorness of infolding, internal breaking and the like does not exist basically; and addition, also with the effect of wind pressure, resin loss is relatively large, and the properties of drop hammer, fatigue and the like of the product are good.

Description

technical field [0001] The invention relates to the technical field of sporting goods processing, in particular to a method for forming an integrated rod by blowing wind. Background technique [0002] In the prior art, the molding of the club generally adopts the thermal expansion molding process of a silicone layer or a silicone film tube filling molding process. [0003] The thermal expansion molding process of silicone beading mainly utilizes the good elasticity of the silicone material and the characteristics of thermal expansion and contraction. At a certain temperature, the silicone material is heated and expanded, giving a certain pressure to the outer fiber layer. Due to the limitation of the external mold, the resin undergoes a cross-linking reaction curing process after the fiber layer is subjected to internal pressure. The product produced by the thermal expansion molding process of the silicone bead has uniform wall thickness and good interlayer bonding; and bec...
