Description
TITLE
DEBURRING TOOL HEAD FIELD
The present disclosure relates to the field of mechanical engineering. In particular, the present disclosure relates to the field of manufacturing tools.
BACKGROUND
Burr is a rough edge or ridge formed on an object, especially of metal, by the action of machining operations such as milling, drilling, grinding, cutting, and the like. These burrs not only affect the aesthetics of the object but can also inflict injuries if the object is handled carelessly. Furthermore, the presence of burrs can also result in an increased wear on the parts involved in a particular operation, thereby leading to frequent replacement or even preventing the parts from working as intended. As such, it is necessary to remove these burrs, and the process by which the burrs are removed is known as deburring. Deburring is generally done manually by the use of tools like a file, a grinding disk, a grinding stone, a grinding tool, sand paper, and the like, which can be used to file down the burrs. However, manual deburring is often time consuming and labor intensive.
Other types of deburring processes include sanding, wire brushing, abrasive flow machining, electrochemical deburring, and electro-polishing. However, these processes are cost intensive and often require specialized setups.
Hence, in order to overcome the aforementioned drawbacks, there is need of a deburring tool head which is cost-friendly and can be used efficiently for manual deburring as well as mechanized deburring.

DETAILED DESCRIPTION
When machining operations are performed on a workpiece, burr is generally formed on the edges of the workpiece. These burrs affect the aesthetics of the workpiece and can also inflict injuries to a human operator if the workpiece is handled carelessly. Also, the presence of burrs can also result in an increased wear on the parts involved in a particular operation, thereby leading to frequent replacement or even preventing the parts from working as intended. Therefore, it is necessary to remove these burrs from the workpiece, and the process by which the burrs are removed is known as deburring. Deburring is generally done manually by the use of tools like a file, a grinding disk, a grinding stone, a grinding tool, sand paper, and the like which can be used to file down the burrs. However, manual deburring is often time consuming and labor intensive.
Other types of deburring processes include sanding, wire brushing, abrasive flow machining, electrochemical deburring, and electro-polishing. However, these processes are cost intensive and often require specialized setups.
In order to overcome the aforementioned drawbacks associated with the conventional deburring methods, the present disclosure envisages a deburring tool head that can be mounted on a shank of a conventional hand-held tool or a shank of a conventional manufacturing machine. As such, the deburring operation can be performed by using the deburring tool head of the present disclosure along with the conventional equipment without requiring specialized setups. Thus, the deburring tool head, as envisaged in the present disclosure, also facilitates the economizing of the deburring process.
Referring to Fig. 1A through Fig. 3, the deburring tool head 100 has a generally conical configuration that is defined operatively between a first operative end 102A and a second operative end 102B thereof. The deburring tool head 100 has at least one arcuate portion 104A, 104B that extends from the first operative end 102A upto the second operative end 102B. The arcuate portion 104A, 104B has an algebraic manifold that is configured to provide relief. At least one flute 106A, 106B is configured on the arcuate portions 104A, 104B to facilitate cutting and easy removal of burrs from the workpiece. The deburring tool head 100 can be mounted on cap/holder which can be connected to the shank of a hand held tool or a machine. More specifically, the cap/holder can hold the deburring tool head 100 at the second operative end 102B which has the larger diameter, and then the cap/holder can be mounted on to the shank of the hand held tool or the machine.
In another embodiment, as shown in Fig. 1A and Fig. IB, the deburring tool head 100 has a web portion 108 defined at the first operative end 102A. An aperture 110 is configured on the web portion 108 to facilitate the mounting of the deburring tool head 100 on a shank (not shown in figures). In this particular embodiment, the deburring tool head 100 includes at least two arcuate portions 104A, 104B that extend from the web portion 108 having the algebraic manifolds configured so as to provide relief.
The flutes 106A, 106B are slot-like formations on the deburring tool head 100 that perform the shearing, cutting, and removal of the burr from the work piece. The flutes 106A, 106B are configured operatively between the two arcuate portions 104A, 104B. As such, the flutes 106A, 106B is defined by the two edges which form the ends of the arcuate portions 104A, 104B. The arcuate portions 104A, 104B have an outer surface 104A1, 104B1 and an inner surface 104A2, 104B2 respectively. Each flute 106A, 106B is provided with two cutting edges wherein one of the cutting edge is configured on the inner surface of the arcuate portion and another cutting edge is provided on the outer surface of the arcuate portion. More specifically, the flutes 106A, 106B are provided with a cutting edge 112A defined on the inner surfaces 104A2, 104B2 of the arcuate portions 104A, 104B. Another cutting edge 112B is defined on the outer surfaces 104A1, 104B1 of the two arcuate portions 104A, 104B. As such, each of the arcuate portions 104A, 104B is provided with one cutting edge 112A configured on the inner surface 104A2, 104B2 at one end thereof, and one cutting edge 112B configured on the outer surface 104A1, 104B1 at the other end of the arcuate portion 104A, 104B. Each of the cutting edges 112A, 112B is provided with a flute angle F° that ranges from 0° to 90°.
Although the deburring tool head 100 of the present disclosure is shown to have two arcuate portions 104A, 104B. The number of the arcuate portions is not restricted to two. The deburring tool head can have more than two flutes as well. The number of the flutes is equal to the number of the arcuate portions. Furthermore, each of the arcuate portions is provided with two cutting edges. As such, the number of the cutting edges 112A, 112B on the deburring tool head 100 will be twice the number of flutes 106A, 106B.
The algebraic manifolds of the at least two arcuate portions 104A, 104B are configured so as to provide relief and facilitate easy removal of the sheared burr during the deburring operation. It is the configuration of the algebraic manifolds of the arcuate portions 104A, 104B which provides a gap to the sheared burr for removal therefrom. The configuration of the flute angles provided to the flutes 106A, 106B also facilitates the easy removal of the burr. Stress concentration occurs at the cutting edges 112A, 112B at the time of deburring, and the surfaces 104A1, 104A2, 104B1, 104B2 of the arcuate portions 104A, 104B act as relief surfaces.
In an embodiment, an apex angle A” of the deburring tool head 100 ranges from 10° to 170°. In another embodiment, the deburring tool head is made of at least one material selected from a group consisting of high speed steel, alloy steel, tungsten carbide, and ceramic duly heat treated.
