Problems solved by technology

[0002] The current high-wall-thickness carbon tube molding methods mostly use molding or vacuum bag molding, OPP winding, and multiple moldings, each time covering a thinner wall thickness to form a high-wall thickness carbon tube; after molding, the inner wall of the carbon tube and Uneven outer wall circumference and poor bonding between layers of composite materials inside carbon tubes, with holes and uneven wall thicknesses; traditional high-wall-thickness carbon tubes have internal layers and uneven wall thicknesses that lead to low quality carbon tubes, such as poor cutting and milling by CNC machining higher

Embodiment 1

[0018] like figure 1 As shown, a high-wall thickness carbon tube forming device described in this embodiment includes a high-pressure pipe body 1, and a tapered collar 3 is respectively connected to the two ends of the high-pressure pipe body 1 through a flange ring 2, and the flange at one end There is a seal between the flange ring 2 and the high-pressure pipe body 1, and there is a through hole after the flange ring 2 at the other end is connected to the high-pressure pipe body 1. The axial direction of the through hole is consistent with the high-pressure pipe body 1 axial direction. A silicone tube 5 is arranged between the collars 3, and the silicone tube 5 is sealed and connected with the conical collar 3. A conical plug 4 is respectively arranged in the conical collar 3 at both ends of the high-pressure pipe body 1, and one end of the The tapered plug 4 is located in the through hole, and a connecting pipe 7 is arranged on the side of the high-pressure pipe body 1. One...

Embodiment 2

[0021] A method for forming a high-wall thickness carbon tube described in this embodiment specifically includes the following steps:

[0022] (1) Cut carbon fiber yarn according to product requirements;

[0023] (2) Choose a steel core bead with appropriate specifications, and put an unsealed nylon membrane tube on the steel core bead;

[0024] (3) Wrap carbon fiber yarn material on the steel core bead covered with nylon film tube to obtain the carbon tube preform;

[0025] (4) Wrap a layer of OPP tape on the carbon tube preform;

[0026] (5) Connect the connecting pipe of the molding device to the vacuum valve, vacuumize the high-pressure pipe body, and the silicone tube in the high-pressure pipe body is adsorbed on the inner wall of the high-pressure pipe body, and then the tapered tubes clamped at both ends of the carbon tube preform The plug and the carbon tube preform penetrate through the through hole, pass through the silicone tube and snap into the tapered collar; t...

Abstract

The invention relates to the technical field of sports goods, and particularly relates to a forming device for a large-wall-thickness carbon pipe. The forming device comprises a high-pressure pipe body, wherein conical lantern rings are connected to the two ends of the high-pressure pipe body through flange rings separately; a silica gel pipe is arranged between the two conical lantern rings; thesilica gel pipe is in sealing connection with the conical lantern rings; conical plug heads are arranged in the conical lantern rings at the two ends of the high-pressure pipe body separately; and theconical lantern ring at one end is located in a through hole. A method for forming a large-wall-thickness carbon pipe through the forming device comprises the procedures of preform preparation, forming and the like. According to the forming device and the forming method for the large-wall-thickness carbon pipe, the high-pressure pipe body is internally filled with a preform, the preform is coatedwith the silica gel pipe, and then the outer wall of the silica gel pipe is pressed by virtue of high-pressure air, so that the same pressure on the preform in a forming process for the preform in the case that a wall thickness is reduced due to resin thinning is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sporting goods, in particular to a high-wall thickness carbon tube forming device and a forming method. Background technique [0002] The current high-wall-thickness carbon tube molding methods mostly use molding or vacuum bag molding, OPP winding, and multiple moldings, each time covering a thinner wall thickness to form a high-wall thickness carbon tube; after molding, the inner wall of the carbon tube and Uneven circumference of the outer wall and poor bonding between layers of composite materials inside the carbon tube, with holes and uneven wall thickness; the internal layering and uneven wall thickness of traditional high-wall carbon tubes lead to low quality carbon tubes, such as poor cutting and milling of CNC processing higher. Contents of the invention [0003] The object of the present invention is to provide a high-thickness carbon tube forming device and a forming method that can ensure hi...
