Description

Diamond pre-milling cutter

Technical Field

The utility model belongs to the technical field of the panel processing cutter and specifically relates to a diamond is milling cutter in advance.

Background

In the existing plate processing process, a pre-milling process needs to be carried out on a plate which is preliminarily cut and formed so as to achieve the effects of removing burrs and flattening the plate. However, the included angle of the prior pre-milling cutter blade is usually 25-30 degrees, the problem of plate black edge caused by unsmooth chip removal in the machining process is solved, and meanwhile, the cutter is high in temperature, large in loss and short in service life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, provide a diamond is milling cutter in advance to improve processingquality, extension cutter life, reduce cost. The technical scheme is as follows:

a diamond pre-milling cutter comprises a cutter body, mounting seats and diamond blades, wherein the mounting seats are arranged on the side surface of a cylindrical cutter body at intervals and are integrally formed with the cutter body; the blades are fixedly arranged on the mounting seat, adjacent blades are arranged in a V shape, the blades are of strip-shaped structures, and the included angle between each blade and the axis of the cylindrical cutter body is 45 degrees; the front side of the blade running direction is provided with a sunken chip groove.

On the basis of the scheme, the chip grooves penetrate through the end faces of the two sides of the cutter body.

On the basis of the scheme, the chip discharge groove is adjacent to and parallel to the blade, and the length of the blade is shorter than that of the chip discharge groove.

On the basis of the scheme, one end of the blade is close to the end face of the cutter body.

On the basis of the scheme, one end of each adjacent chip groove is connected.

Preferably, the mounting seat is provided with a step-shaped clamping groove, and the blade is welded and mounted in the clamping groove.

The utility model has the advantages that: the blade is made of diamond, the inclination of the blade is increased, so that the tool can smoothly discharge chips, the wood discoloration and edge pasting caused by cutting chip retention and poor heat dissipation are prevented, the processing quality is improved, and the processed surface is smooth and flat; the service life of the cutter is prolonged, the cutter cost is saved, and meanwhile, the time for dismounting and debugging is reduced, so that the yield of equipment is improved.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

in the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present invention, it is to be understood that the terms "center", "length", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 1 of the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 and 2, a diamond pre-milling cutter includes a cutter body 1, a mounting seat 2, and a diamond insert 3. The mounting seat 2 is arranged on the side surface of the cylindrical cutter body 1 at intervals and is integrally formed with the cutter body 1, and the blade 3 is fixedly arranged on the mounting seat 2. Preferably, be provided with step draw-in groove on the mount pad 2, blade 3 welded mounting is in the draw-in groove, at blade 3 rotation in-process, by step draw-in groove reinforcing fixed action in blade 3 rear, can not hinder the chip removal of 3 rake faces of blade simultaneously. The adjacent blades 3 are arranged in a V shape, and the blades 3 are of strip structures, so that the leaping of the workpiece during processing is reduced, and the processing precision is ensured. The included angle between the blade 3 and the axis of the cylindrical cutter body 1 is 45 degrees, so that the cutting force is reduced, the chip removal effect is enhanced, and the machined surface is smooth and flat. The front side of the operation direction of the blade 3 is provided with a sunken chip groove 4, the chip groove 4 penetrates through the end faces of two sides of the cutter body 1, the chip groove 4 is adjacent to and parallel to the blade 3, and the length of the blade 3 is shorter than that of the chip groove 4, so that the contact length between the blade 3 and a plate is shortened, the service life is prolonged, the length of wood chips is reduced, the discharge of cutting chips is smoother, the rapid heat dissipation of the blade 3 is facilitated, and the color change and edge pasting of wood due to overhigh temperature are prevented. For improving the chip removal effect, the terminal surface of cutter body 1 is pressed close to the one end of blade 3, and the one end of adjacent chip groove 4 is connected.

The present invention has been described above by way of example, but the present invention is not limited to the above-mentioned embodiments, and any modification or variation based on the present invention is within the scope of the present invention.
