Description

Technical Field

[0001] The utility model relates to the technical field of flange manufacturing, in particular to a carbon fiber ferrule production tooling. Background Art

[0002] The traditional flange includes a flange and a sealing gasket. The hardness of the sealing ring is lower than that of the flange. The sealing principle is to squeeze the sealing ring and form a seal by local plastic deformation. It has no self-tightening function and the seal is easily failed due to external forces.

[0003] In response to the above problems, the applicant developed the ZY-LOC flange, which achieves high-pressure self-tightening sealing by relying on the elastic seal of the T-shaped sealing ring and the sealing cone surface of the sleeve. The ribs of the T-shaped sealing ring are located between the two sleeves, and the two ferrules clamp the sleeve. Under the action of the ferrules, the sleeve and the pipeline form a strong whole; the sealing cone surfaces of the two sleeves and the two lips of the T-shaped sealing ring form a seal respectively.

[0004] In most applications of ZY-LOC flanges, the T-shaped sealing ring is made of high-temperature resistant high-nickel Lo alloy A638GR660, the ball bolts and nuts are made of 35 chromium-molybdenum A, and the ferrules and sleeves are made of 20 manganese. However, when this product is used on aircraft or ships, the user feedback is too heavy, so the material is modified and changed to a flange made of carbon fiber metal composite material. Carbon fiber metal composite material has a lower specific gravity and is more suitable for aerospace and even for daily life connections; and the strength of carbon fiber is also very high, but the shrinkage rate of carbon fiber and steel is different, so it is very difficult to produce and process.

[0026] The production process of carbon fiber ferrules includes primary molding, secondary molding and tertiary molding. Among them, primary molding is rough molding at 100℃ (molding into basic sheet); secondary molding is extrusion heating molding at 200℃ (molding into basic shape and processing hole 6); tertiary molding is precision molding at 380℃ (cutting and precision processing). Through three moldings at different temperatures, the processing of carbon fiber ferrules is realized.

[0027] like Figure 1 As shown, a carbon fiber ferrule production tooling is used in the secondary molding process, comprising an upper die base 1 and a lower die base 2. An arc-shaped groove 3 is provided in the middle of the top of the lower die base 2, and an arc-shaped pressing block 4 matching the arc-shaped depression is provided on the side of the upper die base 1 facing the lower die base 2, which is used to press the block-shaped carbon fiber metal composite material formed by the primary molding process into an arc-shaped portion for clamping the ferrule.

[0030] In some feasible implementations, a guide column 7 is provided at the top edge of the lower die base 2, and a guide hole is provided at the top edge of the upper die base 1, and the guide hole is located in the guide column 7; when the upper die moves up and down under the action of the punch head, the guide column 7 guides the movement path. The top of the guide column 7 is detachably connected to a limit block 8 by bolts, and the size of the limit block 8 is larger than the guide hole, so that when the guide hole and the guide column 7 are assembled, the limit block 8 is bolted to prevent the two from separating.

[0031] In some feasible embodiments, at least one set of heat transfer oil circuits and at least one set of cooling liquid circuits are provided on the upper mold base 1 and the lower mold assembly.

[0038] In this embodiment, the cooling liquid path is connected to a cooling liquid supply device, and the upper and lower mold bases 2 are cooled by providing the cooling liquid path.

[0039] In some feasible embodiments, the arc-shaped pressing block 4 is detachably connected to the pressing block of the upper die seat 1. Since the arc-shaped pressing block 4 is easy to be damaged during stamping, it is designed to be detachable to avoid replacement of the entire structure when damaged.
