Problems solved by technology

The silicone protective cover is soft and has poor deformation resistance. The ordinary U-shaped structure cannot be well fixed with the parts, and the parts are easy to fall off during the turnover process, and the parts are bumped; the silicone protective cover has poor anti-collision performance and cannot effectively prevent impact. Damage to parts; high cost of silicone case
The material of the hard plastic protective cover is relatively hard, which can prevent the damage to the parts due to impact, but it is inconvenient to install and remove the parts, and the service life is short; the ordinary U-shaped structure cannot be fixed with the parts well, and the parts will Easy to fall off, bump parts

Embodiment Construction

[0021] like Figure 1-4 Shown is a turnaround protection device for ring block honeycomb parts, including a protective sleeve 1 and a steel belt 2;

[0022] The opening of the protective cover 1 is an inverted structure 3; the protective cover 1 is a U-shaped arc with an interlayer in the middle;

[0023] The inverted structure 3 forms an angle of 45° with the U-shaped wall of the protective cover 1;

[0024] The steel strip 2 is arranged in the interlayer of the protective sheath 1 .

[0025] The material of the protective cover 1 is PVC, which has elasticity.

[0026] The steel strip 2 is a segmented structure, and there is only a small amount of metal connection between the sections, which can be freely cut at the joints of the steel strip 2 according to the length of the parts.

[0027] The protective cover 1 is reusable.

[0028] The steel strip 2 can be bent arbitrarily.

[0029] The length of the inverted embedded structure 3 is twice the wall thickness of the part...

Abstract

The invention discloses a turnover protective device of ring-block type honeycomb parts. The turnover protective device comprises a protective sleeve and a steel belt. An opening of the protective sleeve is of an inverted-embedded-type structure, the protective sleeve is a U-shaped arc, and an interlayer is arranged in the middle; and an included angle between the inverted-embedded-type structureand a U-shaped wall of the protective sleeve is 45 degrees, and the steel belt is arranged in the interlayer of the protective sleeve. According to the turnover protective device, the technical schemeis simple and convenient, the realizability is high, and the problem that the ring-block type honeycomb parts are prone to colliding with one another is solved.

Description

technical field [0001] The invention relates to the technical field of protection devices, in particular to a turnover protection device for ring block honeycomb parts and a method for using the same. Background technique [0002] The parts of aero-engines include many ring-type honeycomb parts. The wall thickness of the honeycomb unit sash is about 0.05mm, and the rigidity and strength are poor. It is prone to damage during daily production turnover. Once the core lattice of the honeycomb is damaged, it will affect the sealing of the engine parts, so the whole assembly of the brazed honeycomb must be scrapped. Such economic loss is huge, and the factory cannot afford it. Now, factories often use simple U-shaped silicone protective sleeves or hard plastic protective sleeves to protect the honeycomb. The silicone protective cover is soft and has poor deformation resistance. The ordinary U-shaped structure cannot be well fixed with the parts, and the parts are easy to fall o...
