Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and accompanying drawings, which are not intended to limit the present invention.
Referring to fig. 1 to 4, the present invention provides a cutting tool with an arc-shaped cutting portion, including a cutting tool body 1 and a cutting portion 2 disposed on the cutting tool body 1, wherein the cutting portion profile of the cutting portion 2 includes a plurality of outwardly protruding first arc portions 21 and a plurality of inwardly recessed second arc portions 22, one of the first arc portions 21 is located between two adjacent second arc portions 22, and one of the first arc portions 21 is tangentially connected to the adjacent second arc portions 22.
Specifically, in this embodiment, the cutter is used in the press die, two cutters set up upper die base and die holder respectively, the shape of two cutters is the same, two cutters cooperate mutually and are used for cutting the plate, the side end face of cutter body 1 is equipped with cutting part 2, cutter body 1 and cutting part 2 integrated into one piece improve the use intensity, and ensure the accuracy of cutting, cutting part 2 is wavy, constitute by a plurality of first arc 21 and a plurality of second arc 22, a first arc 21 and a second arc 22 set up in turn, the both ends of first arc 21 are tangent with two adjacent second arcs 22 respectively and are connected, so by the plate limit portion that the cutter that has the arcuation cutting part cuts is the tangent arcuation structure in succession.
through setting up the cutter into arcuation cutting part form, the product limit portion of being processed by this cutter is the tangent arcuation in succession, improves the life of cutter, avoids sharp portion to cause the burr problem when plate cuts, realizes the purpose of two plate sharing pressure limit portions simultaneously, reduces the weight of plate when reducing the plate material, reaches the cost of reduction production and transportation.
still include a plurality of connecting portion 23, connecting portion 23 is planar, an tip of connecting portion 23 and adjacent first arc portion 21 tangent connection, another tip and adjacent of connecting portion 23 second arc portion 22 tangent connection, the setting of connecting portion 23 has the purpose that increases vertical distance between the addendum of first arc portion 21 and the tooth root of second arc portion 22, according to actual need, designs the purpose of different tooth heights.
Taking triangular saw teeth as an example, the arc radius of the first arc part 21 is R2-R15 mm, and the arc radius of the second arc part 22 is R2-R15 mm.
Arc radiuses with different sizes are designed according to different thicknesses and materials of machined plate members, preferably, the arc radiuses of the first arc parts 21 are R5mm-R6mm which are common values, and the radiuses of the second connecting parts 215 are R5mm-R6mm which are common values.
The absolute value of an included angle alpha between the end tangent of the first arc part 21 and the central line of the first arc part 21 is 0-75 degrees, preferably, the absolute value of an included angle between the end tangent of the first arc part 21 and the central line of the first arc part 21 is 45 degrees, and the processing effect is optimal.
The tooth height D2 of the first arc part 21 to the second arc part 22 is 10-50mm, and the vertical distance from the tooth top of the first arc part 21 to the tooth bottom of the second arc part 22 is usually determined according to the thickness of the plate to be processed, and the vertical distance is integral multiple of the thickness of the plate.
The tooth spacing D1 of two adjacent first arc parts 21 is 20-100mm, and the center distance is determined according to actual conditions.
The arc radius of the first arc portion 21 is the same as that of the second arc portion 22, so that the cut plate is uniform and symmetrical, the convenience of subsequent processing of products is improved, and the production yield is improved.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
