Abstract

The utility model discloses a thick milling cutter is driven to big surplus of sword that cuts off to V type, include the handle of a knife and locate this handle of a knife one and serve the cutting part, be equipped with a plurality of helicla flute formation chip pockets on the cutting part, a side that each helicla flute corresponds is formed with the side sword, the interval is equipped with a plurality of V style of calligraphy blade on the side sword. The utility model discloses an add V style of calligraphy blade on ordinary cutter and make the side sword form discontinuous promptly disconnected blade to can carry out full sword processing, not only efficiency promotes greatly, is 3 times of conventional cutter, in addition because its life of design of blade also prolongs.

Description

V-shaped broken edge large allowance roughing milling cutter

Technical Field

The utility model relates to a open thick milling cutter, especially relate to a thick milling cutter is opened to big surplus of sword is cut to V type.

Background

At present, in machining, a milling cutter is generally adopted for rough machining, but the common milling cutter is difficult to realize full-cutter machining with large allowance, the machining efficiency is low, and meanwhile, the service life is short. With the development of machining, higher requirements are provided for reducing cost and improving efficiency, and the conventional common milling cutter cannot meet the economic rapid development requirement.

Disclosure of Invention

In order to overcome the defects, the utility model provides a thick milling cutter is driven to big surplus of the disconnected sword of V type can realize full sword processing in the processing, is not only 3 times of general cutter efficiency, and is longe-lived moreover.

The utility model discloses a solve the technical scheme that its technical problem adopted and be: the utility model provides a thick milling cutter is driven to big surplus of V type broken edge, includes the handle of a knife and locates this handle of a knife one and serves the cutting part, be equipped with a plurality of helicla flutes on the cutting part and form the chip pocket, a side that each helicla flute corresponds is formed with the side edge, the interval is equipped with a plurality of V style of calligraphy blade on the side edge.

As a further improvement, the V-shaped cutting edge has a vertical direction to the side edge.

As a further improvement of the utility model, the opening angle of the V-shaped cutting edge is 70-90 degrees.

As a further improvement of the utility model, the helix angle of the spiral groove is 35-45 degrees.

As a further improvement of the present invention, the rake angle of the milling cutter is 10 ° to 14 °.

As a further improvement of the utility model, the core thickness of the milling cutter is 55-65% of the diameter.

As a further improvement of the utility model, the spiral groove is three and evenly arranged on the cutting part.

The utility model has the advantages that: the utility model discloses an add V style of calligraphy blade on ordinary cutter and make the side sword form discontinuous promptly disconnected blade to can carry out full sword processing, not only efficiency promotes greatly, is 3 times of conventional cutter, also prolongs its life owing to the design of blade moreover

5-V-shaped cutting edge.

Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the accompanying drawings.

Referring to fig. 1-3, for the rough milling cutter is driven to big surplus of a kind of V type broken edge, including handle of a knife 1 and locating this handle of a knife and serving one of the cutting part 2, be equipped with a plurality of helicla flutes on the cutting part and form chip pocket 3, this embodiment takes the helicla flute that three evenly set up as the example to explain. A side edge 4 is respectively formed on one side surface corresponding to the three spiral grooves, and a plurality of V-shaped cutting edges 5 are arranged on the side edge 4 at intervals.

The trend of the V-shaped cutting edge 5 is perpendicular to the trend of the side edge 4, and the opening angle of the V-shaped cutting edge 5 is 70-90 degrees.

In addition, the helix angle of the spiral groove is 35-45 degrees, the rake angle 8 of the milling cutter is 10-14 degrees, and the core thickness of the milling cutter is 55-65 percent of the diameter.

The V-shaped broken edge large allowance roughing milling cutter also comprises a cutter handle and a cutting part, is different from the conventional common cutter, has the same side edge cutting edge in a linear form, and has evenly set a V-shaped cutting edge at the side edge cutting edge, so that the cutting edge of the same side edge presents an intermittent form, namely the linear edge adds the V-shaped edge and adds the linear edge and the V-shaped edge to arrange in proper order. When the tool is used, full-cutter machining with large allowance can be carried out, the V-shaped openings are designed to be 70-90 degrees, and the distance and the depth between the V-shaped openings can be designed into coarse teeth, middle teeth or fine teeth according to the size and the cutting allowance of the tool.

Therefore, the utility model discloses an add V style of calligraphy blade and make the side sword form discontinuous promptly disconnected blade on ordinary cutter to can carry out full sword processing, not only efficiency promotes greatly, is 3 times of conventional cutter, in addition because its life of design of blade also prolongs.

In the previous description, numerous specific details were set forth in order to provide a thorough understanding of the invention. The foregoing description is only illustrative of the preferred embodiments of the invention, which can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. All the contents that do not depart from the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention all still belong to the protection scope of the technical solution of the present invention.
