Embodiment Construction

[0023] See figure 1 The molding tool of the extension segment provided by the embodiment of the present invention provides: the support layer 1 and the strain layer 2.

[0024] The support layer 1 is detachably disposed on the compartment section 3.

[0025] The support layer 1 is set within the strain layer 2.

[0026] In the specific embodiment of the present application, since the support layer 1 is sleeved in the strain layer 2, the support layer 1 is mounted on the composite layer 4, in the outer surface of the strain layer 2, the strain layer 2 can be used. The gap between the filled support layer 1 and the composite hot protective layer 4, and the support layer 1 is used to improve the strength, and the portion of the hatch section is maintained, since the support layer 1, strain The layer 2 and the composite protective layer 4 are raised together to obtain a non-rotating body hatch extension, so that the molding of the non-rotating body can be extended, since the support l...

Abstract

The invention discloses a forming tool and using method for an extension section of a non-rotary cabin section, and belongs to the technical field of heat-proof layer composite material forming. The forming tool for the extension section of the non-rotary body cabin section comprises a supporting layer and a strain layer, wherein the supporting layer is detachably arranged on the cabin section, and the supporting layer is arranged in the strain layer in a sleeve mode. According to the forming tool and using method for the extension section of the non-rotary body cabin section, the complete structure of the extension section part after a composite material thermal protection layer is cured is achieved, the operation process is simplified, the material utilization rate and the production efficiency are improved, meanwhile, the forming tool can be repeatedly used, and the tool cost caused by tool damage is reduced.

Description

Technical field [0001] The present invention relates to the field of heat-resistant layer composite material forming techniques, and more particularly to the molding tool and method of use of a non-rotating body hat. Background technique [0002] During the net size molding of the non-rotating body structure, if the composite thermal protective layer structure protrudes the end surface of the metal casing and is a harder trend, the extension is difficult to take out after the composite heat protection layer is solidified. [0003] In the prior art, the composite thermal protective layer of the non-rotating bodies can be reserved after the composite material is reserved after the composite material is reserved, and the method is long, the material utilization rate is low, the material structure The shortcomings of strength and strong dependence of processing equipment. When the composite is cured, the extension tool is removed, and there is a high tooling cost, the process is comp...
