Description

A kind of groove integrated forming knife

technical field

The invention relates to a milling cutter, in particular to a groove integrally formed cutter.

Background technique

Grooves need to be machined on the mobile phone shell. In the past, the milling cutter was placed horizontally, and the blade was set on the side of the cutter bar, and then extended into the mobile phone shell to process irregularly shaped grooves. The above-mentioned processing method is difficult to process, so the applicant designed A one-piece forming knife can process the three sides of the groove by vertical processing, thereby reducing the difficulty of processing.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a groove-integrated knife.

The technical solution adopted by the present invention to solve its technical problems is:

A groove integrally formed knife is characterized in that: it includes a knife rod, a knife neck, and a cutter head arranged in sequence, and a plurality of blades integrally formed with the cutter head are evenly distributed in a ring on the side of the cutter head. The blade includes an arc-shaped rake surface, the first flank on the left, the first flank on the bottom, the first flank on the right, the second flank on the left, the second flank on the bottom, the right The second flank on the side, the rake face intersects with the first flank on the left to form the left cutting edge, the rake face intersects with the first flank on the bottom to form the cutting edge on the bottom, the rake It intersects with the first flank face on the right to form a right cutting edge, the left cutting edge, the bottom cutting edge, and the right cutting edge intersect continuously, the rake face and the side surface of the cutter head form a chip removal groove, the The shapes of the left cutting edge and the bottom cutting edge are arc lines, the shape of the right cutting edge is a straight line, and the left cutting edge, the bottom cutting edge and the right cutting edge are smoothly connected.

The first left flank is smoothly connected to one edge of the first bottom flank, and the other edge of the bottom first flank is smoothly connected to the right first flank.

The second flank on the left intersects the first flank on the left and the second flank on the bottom; the second flank on the bottom also intersects the first flank on the bottom and the second flank on the right The surfaces are all intersected; the second flank on the right also intersects the first flank on the right.

The beneficial effect of the present invention is: the present invention comprises the knife bar, knife neck, cutter head that arranges in order, and the side of described cutter head is annularly uniformly provided with a plurality of blade parts integrally formed with cutter head, and described blade part comprises Arc-shaped rake face, and the first flank on the left, the first flank on the bottom, the first flank on the right, the second flank on the left, the second flank on the bottom, and the second flank on the right flank, the rake face intersects with the first left flank to form a left cutting edge, the rake face intersects with the first flank of the bottom to form a bottom cutting edge, and the rake intersects with the right The first flank intersects to form a right cutting edge, the left cutting edge, the bottom cutting edge, and the right cutting edge intersect continuously, and the rake face and the side surface of the cutter head form a chip flute. Through the above structure, the present invention The tool can vertically process an annular groove with an irregular cross-sectional shape in the mobile phone case, and can process three sides of the groove. At the same time, the structure of the chip removal groove can ensure a large amount of chip removal, and the strength of the blade is high. The setting is convenient for processing in the mobile phone case, thereby reducing the difficulty of processing.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a perspective view of the present invention;

Figure 2 is a partially enlarged view.

Detailed ways

Referring to Fig. 1 and Fig. 2, the present invention discloses a groove integrally formed knife, comprising a knife bar 1, a knife neck 2, and a knife disc 3 arranged in sequence, and the side of the knife disc 3 is evenly distributed in a ring with several The blade portion integrally formed with the cutter head 3, the blade portion includes an arc-shaped rake face 4, a first flank face 5 on the left side, a first flank face 6 on the bottom face, a first flank face 7 on the right side, The left second flank 8, the bottom second flank 9, and the right second flank 10, the rake face 4 intersects with the left first flank 5 to form a left cutting edge 11, so The rake face 4 intersects with the bottom first flank face 6 to form a bottom cutting edge 12, the rake face 4 intersects with the right first flank face 7 to form a right cutting edge 13, and the left cutting edge 11 , the bottom cutting edge 12 and the right cutting edge 13 intersect continuously, the rake face 4 and the sides of the cutter head 3 form chip removal grooves, and the shapes of the left cutting edge 11 and the bottom cutting edge 12 are arc lines , the shape of the right cutting edge 13 is a straight line, and the left cutting edge 11, the bottom cutting edge 12, and the right cutting edge 13 are smoothly connected, so the cross-sectional profile of the final machined groove body is similar to a round bottom V-shape, the structure of the cutter head 3 and the cutter neck 2 is convenient to avoid interference with the workpiece to be processed, which is beneficial to vertical milling.

As shown in the figure, the left first flank 5 is smoothly connected to one edge of the bottom first flank 6, and the other edge of the bottom first flank 6 is connected to the right first flank 7 smooth connection. The left side second flank 8 intersects with the left first flank 5 and the bottom second flank 9; the bottom second flank 9 also intersects the bottom first flank 6 and the right flank. The side second flanks 10 all intersect; the right second flank 10 also intersects the right first flank 7 .

The above is a detailed introduction to the groove integrated forming knife provided by the embodiment of the present invention. In this paper, specific examples are used to illustrate the principle and implementation of the present invention. The description of the above embodiment is only used to help understand the present invention. The method of the invention and its core idea; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and scope of application. In summary, the content of this specification should not be understood To limit the present invention.
