Problems solved by technology

The purchase, use, and maintenance costs of special pultrusion equipment are high, and a large amount of cleaning room area is required; the manufacturing cycle of special forming tooling is long, and the filler in the R area is not easy to demould, and the storage, turnover, and maintenance of the tooling are difficult. It needs to occupy production resources; the shape accuracy of the R-zone filler obtained by manual kneading is low, and the quality consistency is poor

Embodiment Construction

[0022] In the present invention, taking the R-zone filler required for making T-shaped stringers as an example, a hand-held molding device for the R-zone filler includes an upper former 1 and a lower former 2 used in conjunction, and the upper and lower formers are paired. The joint surface is the working surface 3, and the side is provided with a handle 4. The working surface of the lower former 2 is engraved with a gradual groove 5 similar in shape to the filler in the R zone. The cross-sectional size is consistent, the cross-sectional size of the inlet end is 1-2 times the cross-sectional size of the filler in the R zone, and the cross-section smoothly transitions from the inlet end to the outlet end, and the length of the transition zone is 1 / 3 to 1 / 2 of the length of the working surface of the lower former. .

[0023] Forming method of the present invention is as follows:

[0024] 1. Knead the raw materials required for making the filling in the R zone into a loose cylin...

Abstract

The invention discloses a handheld type forming device for a R-zone filler and a forming method. The device comprises two parts: 1) an upper forming unit and 2) a lower forming unit. The device has asimple structure, is portable and can be used for quickly forming the R-zone filler required by the forming of a composite part (component) on a production field; the boundary dimension and interior density of the filler both can meet the requirements; the problem of quick and low-cost preparation of the R-zone filler can be solved.

Description

technical field [0001] The invention relates to the field of manufacturing composite material parts (groups), in particular to a molding device and a molding method for a hand-held R-zone filler. Background technique [0002] In recent years, with the continuous expansion of the application range of composite materials, its manufacturing technology has advanced rapidly, the size of products has continued to increase, and the structure of components (components) has become increasingly complex. Integrate multiple traditional parts into one, and integrated complex parts (groups) that give full play to the performance characteristics of composite materials are emerging, such as typical structures such as reinforced wall panels, box ribs, and ribbed beams. [0003] Restricted by the process characteristics of autoclave molding, parts (assemblies) with complex structures usually need to add R-zone fillers at the joints of different layers in order to avoid cavities and improve th...
