One-step forming process and die of carbon fiber driving shaft

Abstract

The invention discloses one-step forming process and die of a carbon fiber driving shaft. An inner die is in a disk type structure, is partitioned and cut along a center line, is buckled in a flange type and is connected by a bolt. The inner end of an outer die is in a disk structure; the outside of the outer die is in a sleeve structure; and the outer die is portioned and cut along a center line, is buckled in a flange type and is connected by a bolt. The sleeve part of the outer die is transversely cut along a partition surface on one side to form a compressed clamping strip so as to be convenient for fastening a mandrel. Fastening lug seats are correspondingly arranged on the inner die disk and the outer die disk and are provided with bolt holes. The one-step forming process comprises the steps of preparation of the carbon fiber driving shaft, flange preparation and ring flange shaping. In the invention, the ring flange processing die has simple structure, is simple, convenient and feasible for production process and is convenient and quick for processing and using; the one-step forming of the carbon fiber driving shaft and the flange can be realized and the production cost of the die and products can be reduced; the produced carbon fiber driving shaft has high concentricity; the continue track of secondary forming can be eliminated; the torsion strength of the flange of the carbon fiber driving shaft can be enhanced; and the production efficiency and the quality of products can be improved.

Description

technical field [0001] The invention belongs to the technical field of composite material production, and relates to a carbon fiber transmission shaft processing and forming technology. Background technique [0002] At present, the production of carbon fiber transmission shafts at home and abroad are all made of split flanges and shaft tubes separately, and then bonded into a secondary molding process. The process steps are complex, the split flange processing mold structure is complex, and the precision is high. It is labor-intensive and time-consuming, which increases the production cost. The carbon fiber transmission shaft produced is affected by the secondary bonding molding, has poor concentricity and low torsional strength. Contents of the invention [0003] The purpose of the present invention is to provide a carbon fiber transmission shaft one-time molding process and mold to solve the complex structure of the processing mold in the prior art, high precision requir...
