Embodiment 1

[0049] Now take aramid fiber as the elastic core of the middle tube, and make the middle tube sample of 6mm*380mm specification as an example to illustrate the embodiment of the present invention:

[0050] In the production of the actual ball hair racket middle tube, high-precision machinery is mainly used to control various production parameters, and the standard deviation of product performance is small. In order to facilitate the understanding of the processing technology of the present invention, the embodiment uses the most intuitive expression to describe the present invention. .

[0051] The first step is to make the elastic core of the middle tube (such as Figures 1 to 3 shown)

[0052]S1. Cut a number of 500mm long aramid fibers, knead them into a round rod core with a diameter of 1mm, clamp the round rod core at both ends, soak it in epoxy resin diluent for 1min, take it out, dry it, and place it at 150° The epoxy resin is hardened after baking for 150 minutes; th...

Abstract

The invention provides a badminton racket middle tube manufacturing process and a badminton racket middle tube. The badminton racket middle tube manufacturing process comprises the following steps: S1, selecting high-toughness fibers, cutting the fibers to a proper fiber length, twisting the fibers into a round rod core, soaking the round rod core in a thermosetting resin diluent, taking out the round rod core after soaking, airing the round rod core, and hardening the resin; s2, the hardened round rod core is ground to be in a true circle, and a middle tube core part is manufactured; s3, coating the core part of the middle tube with epoxy resin, and airing; s4, cutting a plurality of pieces of epoxy resin-based carbon fiber reinforced prepreg, and laying according to different angles; s5, paving the prepreg and rolling the core part of the middle pipe to obtain a middle pipe preform; s6, uniformly winding an OPP belt on the middle pipe preform, and baking to harden the middle pipe preform into a middle pipe rough blank; and S7, redundant materials of the middle pipe rough blank are cut and ground to be in a true circle, and the middle pipe is manufactured. The method has the advantages that industrial processing is facilitated, and the performance of products in each batch is uniform; the rigidity, impact resistance and bending strength of the whole middle tube can be improved, and the phenomenon that the racket head flies out due to brittle fracture of the middle tube of the racket is avoided.

Description

technical field [0001] The invention belongs to the technical field of sports equipment, and particularly relates to a manufacturing process of a badminton racket middle tube and a badminton racket middle tube. Background technique [0002] Badminton is a very fast transition between offense and defense. The racket frame of badminton racket is formed as a whole because of the network cable weaving. Therefore, the position of the middle tube connected to the racket frame becomes the channel for feedback of the player's force and hitting force, especially in smashing the ball. During the action, in addition to swinging the arm to press the ball down, it is also necessary to use the wrist force and smash to increase the power of the instant shot, so that the ball can gain greater speed and angle. It is easy to deform under large impact and become the most brittle fracture part. [0003] In order to ensure the light weight of the racket and reduce the resistance during swing, i...
