DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] See also Figure 1-3 The utility model provides a technical solution: a high-efficiency lettering chamfering multi-purpose tool, comprising a front end R bottom blade 1, a chamfering blade 2, an outer circumferential blade 3 and a tool handle 4, a front end R bottom blade 1 is provided at the end of the tool handle 4, a chamfering blade 2 and an outer circumferential blade 3 are integrally processed between the front end R bottom blade 1 and the tool handle 4, a double tooth gap groove is provided at the chamfering portion of the chamfering blade 2, and a spiral tool groove 301 is provided along the outer circumferential blade 3.

[0018] The front end R bottom edge 1 is provided with an R angle clearance angle 101 on the blade surface opposite to the transition surface of the workpiece. The R angle design of the R angle clearance angle 101 effectively prevents the blade tip from chipping and ensures the stability of the engraving process.

[0019] Among them, the double tooth gap groove includes a first tooth gap groove 201 and a second tooth gap groove 202. The joints of the first tooth gap groove 201, the second tooth gap groove 202 and the outer circumferential blade 3 are provided with a chamfered first back angle 203 and a chamfered second back angle 204. The first tooth gap groove 201 and the second tooth gap groove 202 ensure the guidance of chip removal during engraving and chamfering cutting, ensure the effective discharge of chips from the front end R bottom blade 1 and the chamfering blade 2, and reduce the sticking and wear of engraving and chamfering.

[0020] Among them, a spiral tool groove 301 is opened at one end of the outer circumferential blade 3 near the chamfering blade 2, and a circumferential blade back angle 302 is formed between the cutting edge of the spiral tool groove 301 and the blade surface opposite to the transition surface of the workpiece. The spiral tool groove 301 effectively guides chip removal and cutting, so that the outer circumferential blade 3 can also participate in the side milling function, so that the tool can not only meet the lettering chamfering function, but also meet other side milling functions, so that it can achieve multi-purpose functions, reduce the tool change frequency, achieve efficient processing, and ensure its cutting stability, meet customers' high-efficiency, high-quality, and long-life processing requirements, thereby reducing customers' costs, improving customers' efficiency, and solving the problems of simple single-item use and chip sticking of existing traditional lettering chamfering.

[0021] Working principle: When in use, the front end R bottom blade 1 and the double tooth gap groove structure of the chamfering blade 2 effectively solve the problem of easy chipping of engraving and chip space, and ensure the chip removal space and rigidity of the tool. The outer circumferential blade 3 is provided with a spiral tool groove 301 to effectively guide chip removal, prevent tool tip chipping and tool breakage, reduce processing costs, shorten processing time, and thus improve processing efficiency.
