Problems solved by technology

[0002] In the processing and production of aluminum alloy supercharger casings, there are often burrs in the hidden holes of the flow passages such as pressure relief and exhaust holes in the finished flow passages. If these burrs are not removed in time, the product quality of the supercharger casing will be affected. , if the product falls into the supercharger during operation, it will directly affect the functionality of the supercharger and bring certain safety hazards. The current method of deburring is to use a file to grind it off. In the flow channel of the finished product, it is easy to interfere with ordinary files and the service life is short, and the removal effect is not good

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0012] Such as figure 1 As shown, the deburring scraper includes a knife handle 1, a knife bar 2, and a knife head 3. The knife handle 1 is fixedly connected to the knife bar 2, and the knife head 3 is arranged on the knife bar. 2, the connection between the cutter head 3 and the cutter bar 2 is a circular arc transition connection, the front end of the cutter head 3 is provided with the cutting edge 6, and the cutting edge 6 is the inner arc 4 and The intersecting surface of the outer arc 5, the ratio of the radius of the inner arc 4 to the outer arc 5 is 8:9, the material of the handle 1 is plastic, and the material of the tool holder 2 is high-speed steel.

[0013] In use, hold the knife handle 1 with the right hand, tilt the scraper, put the knife head into the flow channel, and the cutting edge 6 contacts the burrs at the hidden holes of the flow channel...

Abstract

The invention relates to the field of hand cutting tools, in particular to a deburring scrapper. The deburring scrapper comprises a shank, a scraper bar and a scraper head, and is characterized in that the scraper head is arranged at the front end of the scraper bar, the scraper head and the scraper bar are connected in a circular arc transition manner, a cutting edge is arranged at the front end of the scraper head, the cutting edge is an inner arc and outer arc intersection surface, and the radius ratio between the inner arc and the outer arc is 8:9. Compared with the prior art, the deburring scrapper has the advantages of simple, ingenious and reasonable structure, high efficiency, long service life, lower risk and capability of effectively removing bars at positions of flow-passage hidden holes such as pressure relief and exhaust holes in a flow passage of a supercharger casing.
