Embodiment Construction

[0012] 1. Make mandrels for each part of the impeller group. There are many materials for making mandrels. In this embodiment, gypsum is used. The gypsum material is easy to form, easy to repair, and has good stability. The three-dimensional size of the generated part is 5 mm smaller, and the mandrels of each part of the impeller group include the mandrel of the shaft disc, front disc, wheel disc and three blades;

[0013] 2. Make carbon fiber wet workpieces for each component. Specifically, install a group of carbon fiber bobbins on a rotating movable support, and a group of carbon fiber filaments drawn from a group of carbon fiber bobbins will pass through tension in turn under the traction of the traction equipment. The three rollers, the resin tank and the extruding roller are finally wound on the mandrel of the part. The thickness of the carbon fiber wound on the mandrel of the part is 5 mm to form the carbon fiber wet workpiece of the part. The tension of the three roller...

Abstract

The invention provides a method for manufacturing an impeller unit from carbon fiber filaments. The technical key point is as follow: the method comprises the following steps: a core mould of each part of the impeller unit is made; a set of carbon fiber cone yarns are mounted on a rotary movable bracket, a set of carbon fiber filaments guided out of the set of carbon fiber cone yarns pass through three tension rollers, a resin groove and a rubber extrusion roller in sequence under a traction action of traction equipment and finally wind the core mould of the part, and a wet carbon fiber workpiece of the part is made; all the wet carbon fiber workpieces are heated, so that rubber liquid is solidified and formed, and dried carbon fiber workpieces are formed; the dried carbon fiber workpieces are demoulded; the carbon fiber impeller unit is assembled, and the adjacent carbon fiber parts are adhered by resin and fixed by bolts. The method has the positive benefits that the weight of carbon fibers is equal to 1 / 4 of that of steel with the same volume, the power consumption is reduced, continuous production can be realized in process, and the labor intensity is low.

Description

technical field [0001] The invention relates to a manufacturing method of a fan impeller set, in particular to a method for manufacturing a carbon fiber impeller set by winding carbon fiber filaments. Background technique [0002] The fan impeller set is composed of a shaft disk, a front disk, a wheel disk and three blades, and its material is metal such as steel or aluminum. Whether it is steel or aluminum, they have a common feature of high specific gravity, which leads to the weight of the fan. The power consumed to drive such a fan is also large, and it also increases the burden of transportation and installation. [0003] Carbon fiber is a new material with high strength and low specific gravity, and it has a record of being applied to brackets such as bicycle tripods. If this material can be applied to the impeller set of the fan, the deficiency of the steel or aluminum impeller set can be solved. However, the impeller group is a shipping part, and its structure is c...
