Abstract

The utility model discloses a kind of outer chamfer knives in finishing field, offer several flutings including knife bar and the cutter head that knife bar one end is arranged in, and around the side wall of cutter head, the inside both sides of each fluting tilt inside, and form the cutting edge for cutting flash.The cutter head of the utility model uses flared structure, can remove the burr on workpiece head by the cutting edge of fluting and grind off, while the head of workpiece can be ground various moulding, solve the problems, such as manual polishing, improve processing efficiency；In addition, the end of knife bar can be designed to round, rectangular or pancake, used in order to be adapted to electric drill, impact drill, lathe or milling machine assembling, so that the use scope of the outer chamfer knife is wider.

Description

A kind of outer chamfer knife

Technical field

The utility model relates to finish field more particularly to a kind of outer chamfer knife.

Background technique

Outer chamfer cutter is the indispensable main component of lathe process, and the quality of tool quality influences the use of itself Service life also influences the quality and production efficiency of work pieces process.Currently, the process for being directed to metal head deburring, (such as spiral shell The workpiece such as bar, metal pipe material, plastic pipe, head burr are mostly to carry out manual grinding by sander, are beaten using this kind The working efficiency of mill mode is low, and appearance is not whole, influences beauty.

In order to preferably solve the problems, such as deburring, existing inventor develops a kind of outer chamfer knife, can preferably go Flash removed, while the head of workpiece can be ground into various moulding.

Utility model content

The main purpose of the utility model is to provide a kind of outer chamfer knife, flash removed can be preferably removed, while can be with The head of workpiece is ground into various moulding.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of outer chamfer knife, including knife bar and the cutter head that knife bar one end is arranged in, the knife bar and cutter head are integrally formed knot Structure, the entirety of the cutter head are in horn-like structure, and offer several flutings, the inside of each fluting around the side wall of cutter head Both sides tilt inside, and form the cutting edge for cutting flash.

In above description, more preferably scheme, there are four which is arranged altogether, each fluting it is equal in magnitude.

In above description, more preferably scheme, the end of the knife bar are round, rectangular or pancake.

In above description, more preferably scheme, the front of the fluting are in melon seeds shape.

In above description, more preferably scheme, the knife bar are made with cutter head of wolfram steel material.

The utility model has the following beneficial effects: compared with prior art, the cutter head of the utility model is using tubaeform The burr on workpiece head can be removed by the cutting edge of fluting and be ground off, while the head of workpiece can be ground various make by structure Type solves the problems, such as manual polishing, improves processing efficiency；In addition, the end of knife bar can be designed to it is round, rectangular or flat Flat shape uses in order to be adapted to electric drill, impact drill, lathe or milling machine assembling, so that the use scope of the outer chamfer knife is wider.

In figure: 1, knife bar；2, cutter head；3, it slots；4, cutting edge.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

As shown in Figure 1-3, one of this programme outer chamfer knife, implements structure and includes knife bar 1 and be arranged in knife bar 1 one The cutter head 2 at end, the knife bar 1 are made with cutter head 2 of wolfram steel material, which is an integral molding structure with cutter head 2, described The entirety of cutter head 2 is in horn-like structure, and offers several flutings 3 around the side wall of cutter head 2, and the front of the fluting 3 is in The inside both sides of melon seeds shape, each fluting 3 tilt inside, and form the cutting edge 4 for cutting flash.

The fluting 3 of the present embodiment is altogether there are four settings, each fluting 3 it is equal in magnitude, when cutting the technique of flash, so that knife First 2 is more stable in rotary course.The knife bar 1 of the present embodiment is clamping part, and therefore, end can be round or rectangular, It can be pancake, used in order to be adapted to electric drill, impact drill, lathe or milling machine assembling.

The cutter head 2 of the utility model uses flared structure, can be removed the burr on workpiece head by the cutting edge 4 of fluting 3 Except grinding off, while the head of workpiece can be ground into various moulding, solve the problems, such as manual polishing, improve processing efficiency； In addition, the end of knife bar 1 can be designed to round, rectangular or pancake, in order to be adapted to electric drill, impact drill, lathe or milling machine Assembling uses, so that the use scope of the outer chamfer knife is wider.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
