A kind of manufacturing process of hockey stick

Abstract

The invention discloses a technology for manufacturing a hockey stick. The technology realizes tight fitting of a heat-resistant film pipe and a pressing bar, guarantees tight fitting of a yarn sheet on the heat-resistant film pipe, improves operation efficiency and product quality, and realizes one-piece molding of lines on the surface of a hockey stick striking plate in hockey stick manufacture. The technology comprises the following steps of manufacturing a stick crude blank, manufacturing a hockey stick striking plate crude blank, then carrying out butt joint of the stick crude blank and the hockey stick striking plate crude blank, binding the stick crude blank and the hockey stick striking plate crude blank into an integral body by a binder to obtain a hockey stick crude blank, grinding the hockey stick crude blank, and spraying paint on the surface of the hockey stick.

Description

technical field [0001] The invention relates to a hockey stick, in particular to a manufacturing process of the hockey stick. Background technique [0002] At present, the general production process of the rough billet of the hockey stick is as follows: [0003] A: Set the heat-resistant film tube on the bead, and paste and fix the heat-resistant film tube on the bead by pasting; On the film tube, the yarn material is a yarn material with epoxy resin attached. [0004] B: The bead is pulled out and the heat-resistant film tube remains in the blank of the hollow rod. [0005] C: Put the blank of the pole in the forming mold, and after the mold is closed, use the compression molding process to make the rough blank of the hollow pole; the above compression molding process is as follows: after the mold is closed, heat the mold to melt the epoxy resin on the yarn material ; While heating the mold, blow air into the heat-resistant film tube of the hollow rod blank and pressuriz...

AI Technical Summary

Problems solved by technology

[0010] The first purpose of the present invention is to overcome the gap between the heat-resistant film tube and the bead in the prior art, so that the yarn material cannot be tightly wrapped on the heat-resistant film tube, resulting in repeated rework operations, which seriously affects production efficiency As well as the problem of product quality, provide a hockey stick manufacturing process that can make the heat-resistant film tube and the bead stick tightly; ensure that the yarn material is closely attached to the heat-resistant film tube, thereby improving operating efficiency and product quality

[0012] The third purpose of the present invention on the basis of the first purpose is to overcome the deficiencies in the prior art, and to provide a method that can effectively improve the separation of yarns, unstable loss ratio of epoxy resin and pores, etc. Defective problems, thereby improving product quality, reducing defective scrap rate, improving product strength and effectively controlling the quality of hollow hockey stick hollow pole manufacturing process
