Description

Multi-edge spiral forming T-shaped cutter

Technical Field

The utility model relates to a T type sword technical field specifically is multiple-edged spiral shaping T type sword.

Background

The T-shaped cutter is assembled on a milling machine and used for milling T-shaped grooves and side grooves of a workpiece. The T-shaped cutter is also called as a T-shaped milling cutter, a semicircular milling cutter and a keyway milling cutter, can perfectly process T-shaped grooves and side grooves, normally maintains cutting performance at high temperature, and has higher and higher requirements on the T-shaped cutter in the current market along with the continuous improvement of the requirements of the finish machining industry on the processing efficiency.

However, when the traditional T-shaped cutter in the market is used, the number of the cutting edges is small, the machining resistance during cutting is large, the cutting efficiency is not high, and the waste chips easily block the cutter head in the cutting process to cause cutter explosion.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a multiple-cutting-edge spiral forming T type sword to solve traditional T type sword when using, cutting edge quantity is less, and the processing resistance during cutting is great, leads to cutting efficiency not high, and the easy tool bit that blocks up of cutting process in sweeps, causes the problem of exploding the sword.

In order to achieve the above object, the utility model provides a following technical scheme: multi-edge spiral shaping T type sword, including coaxial and integrated into one piece's handle of a knife, sword neck and tool bit, the tool bit is T type tool bit, the handle of a knife includes connecting portion and the cutting part that mutually perpendicular set up, even spiral array has a plurality of cutting edge on the cutting part lateral wall, adjacent two all be formed with the chip groove between the cutting edge.

Preferably, the end face of the cutting edge is provided with a first cutting edge and a second cutting edge.

Preferably, both end portions of the chip groove extend to both end surfaces of the cutting portion, respectively.

Preferably, the outer diameter of the tool shank is 4mm.

Preferably, the knife handle, the knife neck and the knife head are respectively made of ultra-fine tungsten steel.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a design into 9 with the cutting edge for the cutting edge has reduced the processing resistance, thereby improves the life of cutter, and the both ends of chip groove extend to respectively on the both ends face of cutting portion, can smoothly shunt the chip groove with the sweeps in, and discharge from the bottom of cutting portion fast, avoid the sweeps to pile up the temperature that leads to too high and violent sword phenomenon, extension cutter life.

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 work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the multi-edge spiral forming T-shaped knife comprises a knife handle 10, a knife neck 20 and a knife head 30 which are coaxially and integrally formed. In addition, according to the utility model discloses an embodiment, the external diameter of handle of a knife 10 is 4mm. Additionally, according to the utility model discloses an embodiment, the transition to handle of a knife 10 is passed through to the conical surface structure in the sword neck 20 rear end, and the transition of conical surface structure makes this cutter formable darker slot, and the cutter size is little, is convenient for process less slot. The tool bit 30 is a T-shaped tool bit, the tool holder 10 includes a connecting portion 31 and a cutting portion 32 which are perpendicular to each other, the connecting portion 31 is fixedly connected with the tool neck 20, nine cutting edges 40 are uniformly and spirally arrayed on the side wall of the cutting portion 32, and a chip groove 50 is formed between every two adjacent cutting edges 40. In addition, according to the utility model discloses an on the both ends face of cutting portion 32 is extended respectively to the both ends of chip groove 50, specifically, can smoothly shunt the sweeps in chip groove 50 to discharge from the bottom of cutting portion 32 fast, avoid the sweeps to pile up the temperature that leads to too high and violent sword phenomenon.

Further, by designing the number of the cutting edges 40 to be 9, the cutting edges 40 reduce the machining resistance, thereby improving the service life of the tool.

Referring to fig. 3, in the preferred embodiment, the cutting edge 40 has a first cutting edge 41 and a second cutting edge 42 on the end surface. In addition, according to the embodiment of the present invention, the inclination angle a of the first cutting edge 41 is between 6 ° and 8 °, and the inclination angle b of the second cutting edge 42 is between 13 ° and 17 °.

In the preferred embodiment, the tool holder 10, the tool neck 20 and the tool bit 30 are made of ultra-fine tungsten steel, so that the T-shaped tool has good bending resistance, oxidation resistance, wear resistance and high temperature resistance.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
