Carbon fiber cloth winding forming device for small-diameter shaft products and method for processing shaft products

Abstract

The invention discloses a carbon fiber cloth winding forming device for small-diameter shaft products and a method for machining the same. The carbon fiber cloth winding forming device comprises a mandrel, clamp rings, a front barrier and a rear barrier. The front barrier and the rear barrier sleeve the mandrel; a carbon fiber cloth winding section of the mandrel is formed between the front barrier and the rear barrier; a bushing in the shape of a cone cylinder and a throat liner sleeve the carbon fiber cloth winding section; the throat liner comprises a throat, a first conical section and a second conical section, the throat sleeves the mandrel, the first conical section sleeves a transition conical surface, and the second conical section sleeves an outer conical surface of the bushing; an end surface of the bushing is in contact with the side walls of the rear barrier; corresponding stress surfaces can be respectively formed between the first conical section and the transition conical surface, between the second conical section and the outer conical surface of the bushing and between the end surface of the bushing and the side walls of the rear barrier when carbon fiber cloth is formed by means of winding. The carbon fiber cloth winding forming device and the method have the advantage that the problem of bending deformation or breakage of mandrels of winding mechanisms due to clamping force and tensioning force of carbon fiber cloth when components of small-diameter long hole products are wound can be solved by the aid of the carbon fiber cloth winding forming device and the method.

Description

technical field [0001] The invention relates to a carbon fiber cloth winding and forming device for shaft products with small diameter and a method for processing shaft products, and is especially suitable for winding and forming carbon fiber cloth composite materials for shaft products with small diameter and long holes. Background technique [0002] In the existing technology, the winding equipment is generally an ordinary lathe, and the ordinary winding device has little adaptability, and can only wind shaft products with a large diameter and a small aspect ratio. However, for winding shaft products with small diameters and long holes, ordinary Winding mechanism then can't be finished. The existing small-diameter mandrel 1 includes a shaft body. One end of the shaft body is a large end, and the other end is a small end. Figure 9 , using a common winding mechanism, the snap rings 2 and 3 are stuck on the slots at the large end of the shaft, and then the front baffle 5 is ...
