Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a high-performance cemented carbide rotary file, which solves the problem that when the existing rotary file is in use, there will be debris, dust and other debris attached to the surface of the file, and the debris cannot be removed. Timely treatment will not only cause scratches on the surface of the workpiece, but also make the file dull. At the same time, with long-term use, it will generate a lot of heat. The internal heat is not easy to dissipate, and it is easily affected by high temperature, which seriously affects the file. Performance, causing tool damage, making work efficiency low, and reducing the use of performance problems

Embodiment 1

[0032] see Figure 1-8 , the present invention provides a technical solution: a high-performance cemented carbide rotary file, including a file body 1, a blade groove 2, a flow guiding device 3, and a cleaning device 4. The flow device 3 is arranged inside the file main body 1 and close to the bottom position, and the cleaning device 4 is arranged inside the file main body 1 and close to the position of the flow guiding device 3;

[0033] The inside of the file main body 1 is provided with an air inlet 5 at the position of the blade groove 2, the bottom center of the file main body 1 is threaded with a sealing plug 6, and the inside of the file main body 1 and close to the cleaning device 4 is provided with an air outlet 7 , The top end of the file main body 1 is provided with a pull stud connector 8 .

[0034] Inside and near the bottom of the file main body 1, there is a cavity that is compatible with the flow guiding device 3 and the cleaning device 4. The blade grooves 2 ...

Embodiment 2

[0036] The diversion device 3 is provided with a main filter disc 31, a swirl device 32, and an arc-shaped bar 33. The surface edge of the main filter disc 31 is fixedly connected with the inside of the file body 1, and the swirl device 32 is arranged at the bottom of the main filter disc 31. , the arc surface bar 33 is fixed on the top of the main filter disc 31, when the air flow blows to the inside of the file main body 1 along the air inlet 5, the swirl device 32 is used to make the air flow carry debris under the effect of the swirl flow, It further helps to remove debris. As the airflow rises, it will pass through the main filter disc 31, and then filter out the residual dust. At the same time, when blown by the airflow, the inclined fan blade 43 drives the conical base 42 to rotate , and under the drive of the supporting device 44, the knocking device 45 is also rotated thereupon. At this time, the arc-shaped bar 33 can lift the knocking block 453, and realize knocking o...

Embodiment 3

[0039] The cleaning device 4 is provided with a support 41, a conical base 42, an inclined fan blade 43, a support device 44, and a knocking device 45. The top of the support 41 is fixedly connected to the inside of the file main body 1, and the top of the conical base 42 is lower than the support 41. The central position of the end is rotationally connected, the inclined fan blade 43 is fixed on the surface of the conical base 42 , the supporting device 44 is arranged at the bottom central position of the conical base 42 , and the knocking device 45 is arranged at the bottom of the surface of the supporting device 44 .

[0040] The supporting device 44 is provided with a supporting rod 441, a connecting ball 442, and a ball 443. The top of the supporting rod 441 is fixedly connected with the bottom of the tapered substrate 42, the connecting ball 442 is fixed on the lower end of the supporting rod 441, and the rolling ball 443 is rollingly connected to the connecting ball. 442...

Abstract

The high-performance hard alloy rotary file comprises a file body, a blade groove, a flow guide device and a cleaning device, the blade groove is formed in the bottom of the surface of the file body, the flow guide device is arranged in the file body and close to the bottom, and the cleaning device is arranged in the file body and close to the flow guide device. The rotational flow device is arranged at the bottom of the main filter disc, the cambered surface blocking strip is fixed to the top of the main filter disc, the auxiliary filter screen is fixed to the surface of the cambered surface flow deflector, the semicircular filter element piece is fixed to the end of the surface of the cambered surface flow deflector, and the top end of the semicircular filter element piece is fixedly connected with the bottom of the main filter disc. According to the high-performance hard alloy rotary file, the effects of impurity removal and heat dissipation are achieved, attached impurities can be treated in time, the adhesion situation is not prone to occurring, meanwhile, heat can be dissipated in time, the influence of high temperature is not prone to occurring, the service life of the file is prolonged, safety and reliability are achieved, and the use performance is improved.

Description

technical field [0001] The invention relates to the technical field of rotary files, in particular to a high-performance cemented carbide rotary file. Background technique [0002] The file is made of carbon tool steel T12 or T13 after heat treatment, and then the working part is quenched. It is a production tool. It is a hand tool used for filing workpieces. Carbide rotary files are widely used in machinery, automobile, shipbuilding, chemical industry, craft engraving and other industrial sectors. Non-metal craft engraving, craft gift engraving; cleaning flash, burr and welding seam of casting, forging, welding parts, etc. [0003] At present, when the existing rotary files are in use, there will be debris such as grinding chips and dust attached to the surface of the file, which cannot be dealt with in time, which will not only cause scratches on the surface of the workpiece, but also cause the file to become dirty. Blunt, at the same time, with long-term use, it will g...
