Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and specifically relates to a disposable cutting tool. Background Technology

[0002] Disposable cutting tools typically have multiple cutting edges. When one of the cutting edges wears out or breaks, it can be removed and replaced with a new cutting edge. Replacing the cutting edge of a disposable cutting tool is very simple and usually only takes a few minutes. Therefore, it can effectively reduce machine downtime and increase work efficiency.

[0003] Traditional disposable cutting tools have several mounting slots angled around their perimeter, with each slot angled in the same direction. Each slot contains several fixed cutting blades. When cutting the perimeter of plastic or wooden products, such as... Figure 1 As shown, since the blades inside each mounting slot are separated, the periphery of the product is prone to delamination, requiring subsequent grinding with grinding tools, resulting in low machining accuracy. In addition, since several blades are fixed along the opening angle of the mounting slot, when cutting the periphery of a thinner product, the blades, rotating at high speed, will collectively generate an upward pushing force that causes the product edge to rise, leading to wobbling of the product edge during processing and affecting machining accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a disposable cutting tool that uses a figure-eight shaped distribution of the first blade to improve the stability of cutting the workpiece, and only one first blade is installed in each first mounting slot to avoid the delamination phenomenon of the workpiece after cutting.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A disposable knife, including

[0007] The substrate has a plurality of spaced first mounting grooves around its periphery. The plurality of first mounting grooves are inclined along the axial direction of the substrate, and the inclination directions of each pair of adjacent first mounting grooves are opposite.

[0008] The first blade is provided in several pieces, and the several pieces of the first blade are respectively installed on the side wall of several first mounting slots, with the blades extending out of the first mounting slots.

[0009] The tool holder is fixedly installed at the center of the bottom of the base.

[0010] As a preferred technical solution, the periphery of the substrate is further provided with a plurality of second mounting grooves at intervals. The second mounting grooves are staggered with the first mounting grooves, and the inclination directions of two adjacent second mounting grooves are opposite. The first mounting groove and the second mounting groove have overlapping portions. The lower end of the first mounting groove is located at the lower end of the substrate, and the upper end of the second mounting groove is located at the upper end of the substrate. A second blade is installed on the side wall of the second mounting groove.

[0011] As a preferred technical solution, the number of the first mounting slot and the second mounting slot is four to sixteen, and the number of the first blade and the second blade is four to sixteen.

[0012] As a preferred technical solution, the length of the knife handle is 35mm to 70mm, and the diameter of the knife handle is 20mm to 35mm.

[0013] As a preferred technical solution, the diameter of the substrate is 40mm to 160mm.

[0014] The beneficial effects of this utility model are:

[0015] 1. During use, the figure-eight shaped first blade, under the high-speed rotation of the base, can cancel out the up-and-down swinging force of the first blade on the workpiece, thus preventing the workpiece from swinging and increasing cutting stability.

[0016] 2. Since only one first blade is installed inside each first mounting slot, the workpiece will not separate during cutting, resulting in higher precision.

[0017] 3. Since only one first blade is installed in each first mounting slot, unlike the traditional method of installing multiple first blades in each first mounting slot, the installation efficiency is higher when installing the first blade.

[0018] 4. The first and second mounting slots on the substrate are set in two layers. When installing the first and second blades, the tilt angles of the first and second blades can be adjusted, and the adjustment of the tilt angles can further adjust the surface smoothness of the cut object.

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 2-3 As shown, this utility model provides a disposable cutting tool, including...

[0028] The base 1 has a plurality of spaced first mounting grooves 11 arranged around its periphery. These first mounting grooves 11 are all inclined along the axial direction of the base 1, and the inclination directions of any two adjacent first mounting grooves 11 are opposite. Figure 2 As shown, every two adjacent first mounting slots 11 together form a figure-eight structure. Therefore, the inclination directions of the first blades 2 located inside the two first mounting slots 11 are opposite. When the base 1 rotates at high speed, one of the first blades 2 generates an upward force to push the material, while the other first blade 2 generates a downward force to push the material. Under the action of high-speed rotation, the two forces work together on the material to form a stabilizing force. When cutting thinner materials, the stabilizing effect is good. At the same time, the first mounting slot 11 also has a chip removal function. After cutting, the chips are discharged by inertial centrifugal force.

[0029] The first blade 2 is provided in several pieces, and the several pieces of the first blade 2 are respectively installed on the side wall of several first mounting slots 11 with the blades extending out of the first mounting slots 11.

[0030] The tool holder 3 is fixedly installed at the center of the bottom of the base 1 and is used to connect with the drive end of the drive device.

[0031] Example 2 is a further improvement on Example 1, such as... Figure 4As shown; a number of second mounting grooves 101 are also provided at intervals around the periphery of the base 1. The second mounting grooves 101 are staggered with the first mounting grooves 11. The inclination directions of two adjacent second mounting grooves 101 are opposite. The first mounting grooves 11 and the second mounting grooves 101 have overlapping parts. The lower end of the first mounting groove 11 is located at the lower end of the base, and the upper end of the second mounting groove 101 is located at the upper end of the base 1. A second blade 201 is installed on the side wall of the second mounting groove 101.

[0032] The adjacent first mounting slots 11 and second mounting slots 101 are parallel to each other. Several second mounting slots 101 are located above several first mounting slots 11, and the several second mounting slots 101 are also distributed in a figure-eight shape. The several second mounting slots 101 and several first mounting slots 11 divide the base 1 into upper and lower layers. In this way, more opening angles are available when opening the first mounting slots 11 and second mounting slots 101, increasing the limit range of blade angle. Then, the tilt angles of several first blades 2 and second blades 201 can be adjusted. The adjustment of the tilt angle can increase the surface accuracy of the cut object. The oblique blade has a stronger cutting effect and better cutting surface effect in rotational force, and the applicability is further enhanced. Since the first blades 2 and second blades 201 have overlapping parts, there will be no layering phenomenon after cutting, and the cutting accuracy is high.

[0033] The number of first mounting slots 11 and second mounting slots 101 is four to sixteen, and the number of first blades 2 and second blades 201 is four to sixteen. When using more first blades 2 and second blades 201, the surface accuracy of the object after cutting can be further increased.

[0034] The length of the handle 3 ranges from 35mm to 70mm, and the diameter of the handle 3 ranges from 20mm to 35mm; different lengths and diameters of the handle 3 are suitable for connection to the drive end of different models of drive devices.

[0035] The diameter of the substrate 1 ranges from 40mm to 160mm; the diameter of the substrate 1 can be adapted to the size of the workpiece being processed.

[0036] The device is used as follows:

[0037] First, the blade holder 3 is connected to the drive end of the drive device. After the item is fixed, when cutting the circumference of the item, the base 1 rotates at high speed along the circumference of the item. During this period, since there is only one first blade 2 inside each first mounting slot 11, there will be no delamination after the circumference of the item is cut, and the cutting accuracy is higher. At the same time, since the inclination direction of each pair of adjacent first mounting slots 11 is opposite, the first blades 2 inside each pair of adjacent first mounting slots 11 are distributed in a figure-eight shape. When one of the first blades 2 comes into contact with the item, the item will move along the inclination direction of the first blade 2. Since the inclination direction of the other first blade 2 is opposite, the two forces cancel each other out under the action of high-speed rotation. Therefore, the stability of the item during cutting can be increased, and the edge of the item can be prevented from swinging, which would affect the cutting accuracy.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
