Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a diamond high-gloss scraping blade. Background Art

[0002] The scraper blades in the prior art are all composed of a blade holder and a scraper. Figure 1 As shown in Figure a, a tool groove is set in the tool holder, and the scraper is directly fixed in the tool groove. Since the size of the tool groove is fixed, when the scraper size is larger than the tool groove, or when the scraper needs to move a certain position in the tool groove, the tool groove needs to be reprocessed due to the limited size of the tool groove. This makes the assembly between the tool holder and the scraper more troublesome, and the tool groove is not a through groove, which reduces the efficiency of the manufacturing process. At the same time, due to the processing technology, there is always a process chamfer at the corner of the bottom of the tool groove, such as Figure 1 As shown in b, the chamfering process results in the inability to achieve contact between the end of the scraper and the side wall of the tool groove, resulting in an obvious weld during welding, which looks unsightly.

DETAILED DESCRIPTION

[0022] The technical solutions of the present utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only some of the embodiments of the present utility model, but not all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present utility model.

[0023] Referring to Figures 2-3 , the present utility model provides a technical solution:

[0024] The diamond high light scraper blade comprises a holder 1 and a scraper 2, the holder 1 is provided with a mounting groove, the two sides of the mounting groove are provided with a mounting plane 3 and a bottom support plane 4, the scraper 2 is fixedly arranged on the mounting plane 3 and the end thereof is in abutment with the bottom support plane 4, the cutting edge 5 of the scraper 2 is arranged opposite to the bottom support plane 4, and the included angle θ between the mounting plane 3 and the bottom support plane 4 is 0°<θ<90°. In general, the value of θ is 80°<θ<85°. The holder 1 is a metal or hard alloy holder, the scraper 2 is a diamond high light scraper, the holder 1 and the scraper 2 are fixedly connected by welding, the through mounting groove is arranged on the metal holder, so that the machining difficulty of the mounting groove is reduced, the position of the scraper 2 in the mounting groove can be adjusted, and the size of the scraper 2 can also be reduced in precision requirement. The included angle between the mounting plane 3 and the bottom support plane 4 is controlled to be 80° to 85°, so that the scraper 2 will not act on the process chamfer during the installation of the scraper 2, and the scraper 2 will not fall off from the holder 1 during machining.

[0025] In some embodiments, the cutting edge 5 protrudes to the outside of the end of the holder 1. In which, only the cutting edge 5 of the scraper 2 is in contact with the machined part during the use of the scraper blade, and the holder 1 cannot be in contact with the machined part, so the end of the cutting edge 5 needs to be extended longer. The cutting edge 5 protrudes to the outside of the end of the holder 1 by 0.3mm to 0.5mm, otherwise the holder will be burned during machining of the scraper, and the surface will appear black.

[0026] In some embodiments, a first inclined surface 6 is arranged between the cutting edge 5 and the mounting plane 3. A second inclined surface 7 is arranged between the first inclined surface 6 and the mounting plane 3. The included angle between the first inclined surface 6 and the end plane of the scraper 2 is 0° to 0.5°, and the included angle between the second inclined surface 7 and the end plane of the scraper 2 is 2° to 15°. The first inclined surface 6 supports the cutting edge 5, therefore, the cutting edge 5 can be arranged with a small angle, commonly 0.3° and 0.4°, or not inclined, in order to better remove the waste generated during machining, therefore, the second inclined surface 7 must be inclined, and the commonly used inclined angles are 10°, 12° and 15°.

[0027] In some embodiments, the thickness of the first inclined surface 6 is 0.2 to 0.5mm. In which, the commonly used thickness of the first inclined surface 6 is 0.2mm, 0.3mm, 0.4mm and 0.5mm.

[0028] In some embodiments, a first circular arc groove 8 is arranged on the middle part of the scraper 2, and a second circular arc groove 9 matched with the first circular arc groove 8 is arranged on the end part of the tool holder 1.

[0029] In some embodiments, a through mounting hole 10 is arranged on the middle part of the tool holder 1. The mounting hole 10 is arranged to facilitate the bolt fixation of the tool holder 1 on a tool equipment, thus facilitating the disassembly and adjustment.
