Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the following detailed description.

Example 1

Referring to fig. 1-3, the present embodiment provides a hub cutting tool with a chip breaker that includes a tool bar 2, a blade 1 fixed to one end of the tool bar 2, and a chip breaker plate 3 detachably connected to the top of the tool bar 2. The turning chips collide the edge of the chip breaking plate 3 to become chips, so that the chip breaking function is realized, and meanwhile, the chip breaking plate 3 reduces the strength loss of the cutter bar 2 to the maximum extent.

In a further optimized scheme, an included angle is formed between the rear cutter face of the blade 1 and the horizontal plane, and the tail end of the blade 1 does not exceed the top face of the chip breaking plate 3.

Further optimizing the scheme, the included angle is 5 degrees.

In a further optimized scheme, one side of the chip breaking plate 3, which is close to the blade 1, is parallel to the side wall of the cutter bar 2.

Further optimize the scheme, cutter arbor 2 and blade 1 are the welding integrated into one piece structure.

Further optimization scheme, a plurality of mounting holes 4 have been seted up to chip-breaker plate 3 top surface, and chip-breaker plate 3 and cutter arbor 2 can dismantle through a plurality of screws and connect.

The polycrystalline diamond is adopted in the embodiment, the radius of the blade 1 is R2.5, and the cutter bar 2 is designed in the specification of 25mm multiplied by 180 mm; the cutter bar 2 and the cutter blade 1 are integrally welded, the chip breaking plate 3 is 4.0mm thick, sharp corners are reserved at chip breaking parts, and M4 screws are adopted for fastening; the turning scraps flow to the root of the scrap breaking plate 3, the scrap breaking effect is obvious, the installation is convenient, and the whole cutter can be connected with a cutter tower of a machine tool. The cutter of the embodiment has an obvious chip breaking effect, and the aluminum chips are changed into chips from a strip winding shape; the structure is simple and practical, the operation is easy, the replacement is convenient, and the strength of the cutter head can be kept on the premise of ensuring the chip breaking effect; the cost is reduced, the strength of the chip breaking part of the cutter head is not enough before improvement, the cutter is damaged frequently, the service life of the cutter is prolonged by 3 times after improvement, the chip breaking plate 3 can be replaced at any time, and the chip breaking plate can be detached when chip breaking is not needed, so that the operation is convenient.
