Embodiment Construction
[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Embodiments of the combined mandrel for fiber tube braiding provided by the present invention:
[0028] Such as figure 1 with figure 2 As shown, the combined mandrel for fiber tube braiding includes a first plug-in component 1 and a second plug-in component that are plug-fitted. The first plug-in component 1 extends along the front-to-back direction, and the second plug-in component has a The slot where the plug-in part 1 is inserted. After the first plug-in part 1 is plugged into the second plug-in part, together with the second plug-in part, the formed outer peripheral surface whose axis extends in the front and rear direction is formed. The shaped outer peripheral surface is used for supplying Filament winding and braiding; in this embodiment, the first plug-in component 1 is metal.
[0029] It is defined that the first plug-in...

The invention relates to the technical field of fiber pipe manufacturing, in particular to a composite mandrel for fiber pipe weaving. The composite mandrel for fiber pipe weaving comprises a first inserting connection part and a second inserting connection part; the first inserting connection part extends in the front-back direction; the second inserting connection part comprises two or more forming sheet bodies extending in the front-back direction, the front ends of the forming sheet bodies are fixed relatively, the rear ends of the forming sheet bodies are suspended, and the suspended parts of the forming sheet bodies are arranged at intervals and form inserting grooves for allowing the first inserting connection part to be inserted from back to front; the first inserting connection part and the second inserting connection part are inserted in the front-back direction and jointly form a forming periphery surface of which the axis extends in the front-back direction, and the formingperiphery surface is used for fiber winding, weaving and forming; and the inserting matched surfaces of the first inserting connection part and the second inserting connection part are wedge surfaces. The composite mandrel for fiber pipe weaving can be used for solving the problem that in the prior art, a mandrel cannot be easily pulled out from a fiber pipe.
Description
technical field [0001] The invention relates to the technical field of fiber tube manufacturing, in particular to a combined mandrel for fiber tube braiding. Background technique [0002] During the manufacturing process of the fiber tube, it needs to rely on the mandrel to achieve the shape. The specific processing process of the fiber tube is as follows: first select the mandrel with the appropriate specification, then fix the mandrel in the special equipment, and then wind the fiber of the braided fiber tube The outer periphery of the mandrel is woven into a fiber preform, and then the fiber preform is solidified with a matrix material to form a fiber tube. After the fiber tube is formed, it is cut according to the required size, and finally the mandrel is taken out of the completed fiber tube. [0003] Due to the close fit between the formed fiber tube and the mandrel, it is difficult to remove the mandrel from the fiber tube without damaging the fiber tube. Contents o...
