Manufacturing method and equipment for middle tube of badminton racket

Abstract

The invention discloses a manufacturing method for a middle tube of a badminton racket. The method comprises the following steps that a core material mold is prepared; carbon fiber cloth is wound on the core material mold to form a carbon rod structure; a pressure belt is wound outside the carbon rod structure; the carbon rod structure wound with the pressure belt and the core material mold are put into pressurizing and heating equipment together to be pressurized and heated, so that the carbon rod structure is cured and formed; and the pressure belt outside the carbon rod structure is removed, and the core material mold in the carbon rod structure is pulled out. Meanwhile, the invention discloses manufacturing equipment applied to the manufacturing method of the middle tube of the badminton racket. According to the manufacturing method and equipment of the middle tube of the badminton racket, the middle tube does not need to be ground in the manufacturing process, the continuity of carbon fibers in the middle tube and the integrity of a resin protection layer on the surface of the middle tube are ensured, the curing effect of the carbon fibers and resin is enhanced, the use amount of the carbon fibers is reduced, the production process is optimized, the production cost of the middle tube of the badminton racket is saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a method for manufacturing a badminton racket center tube and manufacturing equipment for making a badminton racket center tube. Background technique [0002] Badminton is a sport that can be played both indoors and outdoors. Usually two or four people are divided into two groups, and they take turns facing each other and hit the ball with feathers across the net in the middle of the court with a racket with a handle. A general badminton racket is composed of a frame, a middle tube, a front cover, a handle and other accessories. Among them, the middle tube is one of the most important components of a badminton racket, which has a vital impact on the overall performance and user experience of the badminton racket. . [0003] The middle tube of better quality badminton racket is generally made of carbon fiber material with superior performance. The production method of carbon fiber...

Problems solved by technology

[0004] However, there are many problems in this production method: first, the pressure generated by the thermal shrinkage of the OPP tape is very limited, and the pressure generated by the shrinkage is unstable, which is not conducive to the curing and molding of epoxy resin and carbon fiber cloth, which is easy to cause The strength of the middle tube is unstable; secondly, the shrinkage and extrusion of the OPP belt will cause a lot of scratch marks on the outer surface of the rough billet of the middle tube. The scratch marks on the surface of the rough blank of the middle tube are worn away, but the grinding process will cause damage and fracture of the carbon fibers on the surface of the middle tube. For carbon fibers with strong directivity, the damage or breakage of the fibers will seriously affect its performance, resulting in the The performance of the carbon fiber in the center cannot be brought into full play; thirdly, the grinding process will wear off the resin protective layer on the surface of the center tube, exposing the carbon fiber, and when it collides with other objects, it is easy to cause fiber damage and cause the center tube to break; Fourth, since the center tube needs to be ground during processing, it is necessary to stack the material structure of about 2%-5% of the standard parts in multiple rows when wrapping the carbon fiber cloth, as the material to be ground, so as to ensure that the center tube after grinding has a Qualified size, this method will increase the carbon fiber cloth material of the middle tube, and increase the production cost of the middle tube
