Abstract

The utility model discloses a limiting cutting knife which comprises a first round hobbing cutter limiting gasket, a round hobbing cutter blade and a second round hobbing cutter limiting gasket, wherein the round hobbing cutter blade is positioned between the first round hobbing cutter limiting gasket and the second round hobbing cutter limiting gasket, and the diameter of the round hobbing cutter blade is larger than the diameter of the first round hobbing cutter limiting gasket and the diameter of the second round hobbing cutter limiting gasket. The round rolling cutter can achieve the effect of accurately controlling the depth of the cut composite coating material. Compared with common circular hobs and cutting knives in the market, the cutting knife has the advantages of sharper cutting effect, more stable cutting depth, longer service life, better flexibility, heat resistance and corrosion resistance.

Description

Limiting cutting knife

Technical Field

The utility model relates to the field of limiting and cutting of multilayer composite coating materials, in particular to a limiting cutting knife.

Background

At present, when the multilayer composite coating material is applied to the surface of an aircraft, a handheld cutting tool is mainly divided into an art designing cutter and a circular hob, when cutting is performed, basically, a cut object is completely cut according to the required size, the layered cutting effect of the multilayer composite coating material cannot be realized, even if the circular hob capable of controlling the cutting thickness on the market is adopted, because the thickness of each layer of coating of the multilayer composite coating material is thinner and is generally between 15 micrometers and 30 micrometers, other coatings are very easy to scratch, at present, the layered cutting effect is mainly achieved by cutting the multilayer composite coating material through modes of machining, molds and the like, and the process is complex and not convenient enough. At the present stage, with the continuous development of the application of the composite coating material, the application environment becomes more complex, the cutting method also needs a more effective and convenient mode, and particularly when the multi-layer composite coating material on the surface of the aircraft is cut, the conventional cutting tool on the market can not control the proper cutting depth, the damage to the surface of the aircraft substrate or the damage to the undamaged coating can be caused when the material is cut, the damage to the surface of the aircraft can influence the special performance of the surface coating of the aircraft and can have serious potential safety hazard, therefore, according to the phenomenon problem, the cutting circular knife capable of limiting the cutting is invented according to the thickness of the multi-layer composite coating material, by changing the limiting pieces at the two sides of the knife blade, the circular rolling cutter with specific cutting thickness can be obtained, so that the surface of the aircraft or an undamaged coating is not damaged, and an ideal cutting effect is achieved.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the limiting cutting knife provided by the utility model solves the problem of limiting cutting of a multi-layer composite coating material.

In order to achieve the purpose of the utility model, the utility model adopts the technical scheme that: the utility model provides a spacing sword that cuts, includes first round hobbing cutter spacing gasket, round hobbing cutter blade and second round hobbing cutter spacing gasket, and round hobbing cutter blade is located between first round hobbing cutter spacing gasket and the second round hobbing cutter spacing gasket, and the diameter of round hobbing cutter blade is greater than the diameter of first round hobbing cutter spacing gasket and second round hobbing cutter spacing gasket.

Furthermore, the diameters of the first round hobbing cutter limiting gasket and the second round hobbing cutter limiting gasket are the same.

Furthermore, the first round hobbing cutter limiting gasket, the round hobbing cutter blade and the second round hobbing cutter limiting gasket are provided with a common positioning hole.

Further, the first round hob limiting gasket and/or the second round hob limiting gasket comprise a temperature sensing color changing material.
