Carbon fiber cloth composite pre-forming mold and pre-forming process thereof

Abstract

The invention discloses a carbon fiber cloth composite preforming mold and a preforming process thereof.The carbon fiber cloth composite preforming mold comprises a base, a supporting column is installed on the base, the supporting column and a rotating cylinder are assembled in a circumferential rotation mode through a slewing bearing, the rotating cylinder is sleeved with a rotating large gear, and the rotating large gear is in meshing transmission with a rotating small gear; a motor shaft of the rotating motor is sleeved with the rotating pinion; the rotating cylinder is installed on the inner side of the rotating table, a protective cover is installed on the outer side of the rotating table, a supporting table is installed between the protective cover and the rotating cylinder, external driving mechanisms are installed on the supporting table, lower dies are installed on the rotating table, each lower die corresponds to one external driving mechanism, and the external driving mechanisms are used for driving pressing bases on the lower dies to move. Therefore, the edge of the carbon fiber cloth is compressed and loosened; each lower die corresponds to one upper die, and the upper dies are used for being matched with the lower dies to press the carbon fiber cloth needing to be compounded so that the carbon fiber cloth can be formed; the upper die is installed on the upper die frame, and the upper die frame is installed on the base.

Description

technical field [0001] The invention relates to a carbon fiber cloth composite material forming technology, in particular to a carbon fiber cloth composite preforming mold and a preforming process thereof. Background technique [0002] Carbon fiber is generally made of carbon fiber cloth. There are two main ways to compound it with other materials. The first is to cover one or more layers of carbon fiber cloth on the surface of the formed workpiece, and use glue (epoxy resin) to glue the carbon fiber cloth Tightly compound on the formed workpiece, thereby improving the texture and quality of the workpiece. The other is to form by bonding multiple layers of carbon fiber cloth with glue. The carbon fiber cloth obtained in this way has the main characteristics of carbon fiber, so it is a commonly used molding method at present. Regardless of the molding method, the current operation steps are roughly as follows: [0003] 1. Make a mold, if it is covered on the workpiece, dire...

AI Technical Summary

Problems solved by technology

Therefore, at present, the composite molding of complex curved surfaces mainly relies on manual labor, which requires high experience and technology, but the defective rate is still high.

Even if the corresponding mold is made separately for each layer, this kind of problem will still occur due to the actual thickness deviation of the carbon fiber cloth, the precision of the mold is not high enough, and the direction of the mold pressing down is deteriorated.

Therefore, the cost of carbon fiber composite molding with complex curved surfaces remains high at present, which poses a challenge to mass production
