Description

Insert body and indexable cutting tool Technical Field

[0001] This invention relates to the field of cutting tool technology, and more specifically, to a cutting tool body and an indexable cutting tool. Background Technology

[0002] Indexable cutting tools are key components in modern machining. By setting multiple indexable cutting edges on the insert body, a new cutting edge can be used after a single cutting edge wears out, thereby improving the overall tool life and machining efficiency. However, with traditional insert bodies, the actual effective utilization rate of each cutting edge is low, which wastes the design potential of the tool and limits the applicable working conditions of the tool, leaving room for improvement. Summary of the Invention

[0006] According to an embodiment of the present invention, the insert body has grooves respectively set on two adjacent cutting surfaces, so that the two grooves are arranged on both sides of the cutting edge. The insert body can use the cutting surface of any side of the cutting edge as the main rake face for cutting by indexing. The cutting edge can be used for multiple cutting flow directions, which improves the utilization rate of the cutting edge and expands the applicable working conditions of the insert body. The indexable cutting tool can dynamically change the function of the grooves according to the cutting orientation. This allows a cutting edge to have complete chip breaking and air clearance functions in two indexing uses. It does not increase the manufacturing cost excessively, and can solve the problems of low utilization rate and poor adaptability of traditional cutting tools, thereby improving the overall service life and economy of the tool.

[0007] According to an embodiment of the present invention, the grooves on two adjacent cutting surfaces are arranged symmetrically with respect to the cutting edge at the intersection.

[0008] According to an embodiment of the present invention, the cutting edge is further provided with a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge being located on both sides of the cutting edge and extending along the extension direction of the cutting edge.

[0009] According to an embodiment of the present invention, the first cutting edge and the second cutting edge are arranged symmetrically with respect to the cutting edge.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] The indexable cutting tool 1000 according to an embodiment of the present invention is described below with reference to Figures 1-7. The indexable cutting tool 1000 includes a cutting edge body 100 having a cutting edge 20. The indexable cutting tool 1000 also includes a tool body 200, on which the cutting edge body 100 is disposed. The cutting edge body 100 can be indexed on the tool body 200 to switch to a new cutting edge 20.

[0039] As shown in Figures 1-6, according to an embodiment of the present invention, the blade body 100 has a plurality of cutting surfaces 10, and a cutting edge 20 is provided at the intersection of at least two adjacent cutting surfaces 10. Each of the two cutting surfaces 10 is provided with a groove 101, and the groove 101 of each cutting surface 10 is adjacent to the cutting edge 20 and extends along the extension direction of the cutting edge 20.

[0040] The cutting surface 10 is the outer surface of the insert body 100. The cutting edge 20 is used to remove excess material from the workpiece. The groove 101 is a groove formed by an inward indentation of a part of the cutting surface 10. Since long chips can entangle the tool and the workpiece, making it impossible to continue processing and affecting processing efficiency, and long chips are also unsafe for the operator, a groove 101 is provided on one side of the cutting edge 20 to perform chip breaking function and form short chips, thereby controlling the chip flow and ensuring processing efficiency and safety. A groove 101 is provided on the other side of the cutting edge 20 to avoid processing interference.

[0041] By setting a groove 101 on each side of the cutting edge 20, when the cutting edge 20 participates in cutting and uses different cutting surfaces as the main rake face, the two grooves 101 can play different functions. One groove 101 plays the role of chip breaking, forming a chip breaking groove, while the other groove 101 plays the role of air clearance, forming an air clearance groove. This design makes the indexable cutting tool 1000 more adaptable to different machining methods (such as climb milling and conventional milling). No matter what working position the insert body is in, one groove 101 can always play the role of chip breaking, while the other groove 101 plays the role of air clearance. Thus, a stable and reliable chip breaking effect can be guaranteed under various working conditions, and cutting interference can be effectively avoided, improving the surface quality of the machined surface and operational safety.

[0042] For example, a first cutting edge 21 is provided at the intersection of the first cutting surface 11 and the second cutting surface 12. The first cutting surface 11 has a first groove 111, and the second cutting surface 12 has a second groove 121. The first groove 111 and the second groove 121 are respectively adjacent to the first cutting edge 21 and extend along the extension direction of the first cutting edge 21. When the insert body 100 is in the first working position and the first cutting surface 11 is used as the main rake face, the first groove 111 is a chip breaker groove, and the second groove 121 is a clearance groove. When the insert body 100 is indexed and in the second working position, and the second cutting surface 12 is used as the main rake face, the second groove 121 is a chip breaker groove and the first groove 111 is a clearance groove. That is, when the insert body 100 is indexed and the other side of the same cutting edge 20 is used for cutting, the groove 101 used for chip breaking can be used as a clearance groove and the groove 101 used for clearance can be used as a chip breaker groove. This makes the cutting edge 20 suitable for multiple cutting flow directions, improves the utilization rate of the cutting edge 20, and expands the applicable working conditions of the insert body 100.

[0043] According to an embodiment of the present invention, the insert body 100 has grooves 101 respectively provided on two adjacent cutting surfaces 10, so that the two grooves 101 are arranged on both sides of the cutting edge 20. The insert body 100 can use the cutting surface 10 on either side of the cutting edge 20 as the main rake face for cutting by indexing. The cutting edge 20 can be used for various cutting flow directions, which improves the utilization rate of the cutting edge 20 and expands the applicable working conditions of the insert body 100. The indexable cutting tool 1000 can dynamically change the function of the groove according to the cutting orientation. This allows a cutting edge 20 to have complete chip breaking and air clearance functions in two indexing uses, which will not increase the manufacturing cost excessively, and can solve the problems of low utilization rate and poor adaptability of traditional cutting tools, thereby improving the overall service life and economy of the tool.

[0044] As shown in Figures 1 and 5, in some embodiments, the grooves 101 of two adjacent cutting surfaces 10 are symmetrically arranged with respect to the cutting edge 20 at the intersection line. Thus, the structures of the grooves 101 on both sides of the cutting edge 20 are exactly the same. When either cutting surface 10 is used as the main rake face, the grooves 101, as chip breaker grooves, can achieve the same chip breaking effect. The chip breaker grooves maintain a set cross-sectional shape and depth, which can effectively control the curling and breaking of chips, reduce cutting resistance, and promote the dissipation of cutting heat. The grooves 101, as clearance grooves, can effectively avoid cutting interference, thereby improving the surface quality of the machined surface and operational safety.

[0045] Of course, the grooves 101 on both sides of the cutting edge 20 can also be designed as an asymmetrical structure.

[0046] As shown in Figure 6, in some embodiments, the cutting edge 20 is further provided with a first cutting edge 30 and a second cutting edge 40. The first cutting edge 30 and the second cutting edge 40 are located on both sides of the cutting edge 20, and the first cutting edge 30 extends along the extension direction of the cutting edge 20, and the second cutting edge 40 also extends along the extension direction of the cutting edge 20. By setting the first cutting edge 30 and the second cutting edge 40, the strength of the cutting edge 20 can be enhanced, the risk of chipping can be reduced, and the distribution of cutting force can be improved.

[0047] As shown in Figure 6, in some embodiments, the first cutting edge 30 and the second cutting edge 40 are arranged symmetrically with respect to the cutting edge 20, thereby making the strength on both sides of the cutting edge 20 the same, ensuring that the cutting edge 20 can achieve a reliable and effective cutting effect when any cutting surface 10 is used as the main rake face.

[0048] Of course, the first cutting edge 30 and the second cutting edge 40 on both sides of the cutting edge 20 can also be designed as an asymmetrical structure.

[0049] As shown in Figure 1, in some embodiments, each of the two adjacent cutting surfaces 10 is provided with a support protrusion 102. The outer surface of the support protrusion 102 can be designed as a plane, which is parallel to the reference plane of the cutting surface 10. In the direction perpendicular to the cutting surface 10, each support protrusion 102 protrudes from the cutting edge 20. Thus, during machining, the support protrusion 102 can play a supporting role and can abut against the tool body 200. Since the support protrusion 102 protrudes from the cutting edge 20, interference between the cutting edge 20 and the tool body 200 can be avoided.

[0050] As shown in Figure 4, in some specific examples, the distance between the support protrusion 102 and the cutting edge 20 in the direction perpendicular to the cutting surface 10 is H, where 0.08mm≤H≤0.3mm.

[0051] As shown in Figure 1, in some embodiments, each support protrusion 102 has a positioning structure 1021 for connecting to the tool body 200 of the indexable cutting tool 1000. For example, the positioning structure 1021 can be a positioning hole. The support protrusion 102 is connected to the tool body 200 through a fastener passing through the positioning hole. For example, the diameter of the positioning hole is D, 3.5mm≤D≤10mm, so that the blade body 100 can be installed on the tool body 200. Thus, each support protrusion 102 can be used as a positioning structure connected to the tool body 200, so that the support protrusion 102 can play a positioning and fixing role. The blade body 100 can be installed on the tool body 200 through multiple support protrusions 102.

[0052] As shown in Figure 6, in some examples, the cutting edge 20 can be designed to be rounded, and the radius R of the rounding satisfies: 0.02mm≤R≤0.15mm.

[0053] In some examples, the cutting edge 20 includes multiple cutting edges 20, which extend in different directions and are connected in sequence. The cutting edges 20 can be arranged circumferentially along a cutting surface 10. Correspondingly, the groove 101 extends circumferentially along the cutting surface 10 in which it is located.

[0054] In some embodiments, the cutting surface 10 includes a top cutting surface, a bottom cutting surface, and a peripheral cutting surface. The top cutting surface can be the first cutting surface 11 in FIG2, the bottom cutting surface is the fourth cutting surface (not shown in the figure), and the peripheral cutting surface is connected between the top cutting surface and the bottom cutting surface. The peripheral cutting surface includes a plurality of side cutting surfaces connected in sequence, such as the second cutting surface 12, the third cutting surface 13 in FIG2, and the fifth cutting surface (not shown in the figure) arranged opposite to the second cutting surface 12 and the sixth cutting surface (not shown in the figure) arranged opposite to the third cutting surface 13. A cutting edge 20 is provided at the intersection of the peripheral cutting surface and the top cutting surface, such as the first cutting edge 21, the second cutting edge 22, the eighth cutting edge 28, and the ninth cutting edge 29 as shown in FIG1 and FIG2. A cutting edge 20 is provided at the intersection of the peripheral cutting surface and the bottom cutting surface, such as the fourth cutting edge 24 and the fifth cutting edge 25 as shown in FIG1. ​​In addition, a cutting edge 20 is provided at the intersection of two adjacent side cutting surfaces, such as the third cutting edge 23, the sixth cutting edge 26, and the seventh cutting edge 27 as shown in FIG1 and FIG2.

[0055] Therefore, compared with traditional blades, the number of cutting edges 20 is increased, which can improve the utilization rate of the blade body 100 and increase the service life of the blade body 100.

[0056] It is understood that the top cutting surface, bottom cutting surface and multiple side cutting surfaces are respectively provided with support protrusions 102, and the support protrusions 102 have positioning structures 1021, thereby enabling the insert body 100 to be mounted on the cutter body 200 through more support protrusions 102, so as to realize the multiple indexing and use of the insert body 100.

[0057] In some specific examples, the top cutting surface is a polygon, and the intersection of the side cutting surface and the top cutting surface has multiple corresponding cutting edges 20. The bottom cutting surface is a polygon, and the intersection of the side cutting surface and the bottom cutting surface has multiple corresponding cutting edges 20. The top cutting surface and the bottom cutting surface can be quadrilateral, pentagon, hexagon, etc., so that the entire insert body 100 is prismatic, with a cutting edge 20 at each edge, increasing the number of cutting edges 20.

[0058] As shown in Figure 1, each cutting edge 20 has a groove 101 on both sides. This allows the two grooves 101 to perform different functions when each cutting edge 20 uses a different cutting surface as the main rake face. One groove 101 performs chip breaking function, forming a chip breaking groove, while the other groove 101 performs air clearance function, forming an air clearance groove. This design makes the indexable cutting tool 1000 more adaptable to different machining methods (such as climb milling and conventional milling). No matter what working position the insert body 100 is in, as long as any cutting edge 20 participates in cutting, one groove 101 can always play the role of chip breaking, while the other groove 101 plays the role of air clearance. This ensures stable and reliable chip breaking effect under various working conditions, effectively avoids cutting interference, and improves the surface quality and operational safety of the machined parts.

[0059] In some specific embodiments, a cutting edge 20 is provided at the intersection of any two adjacent cutting surfaces 10, and any two adjacent cutting surfaces 10 are arranged symmetrically. By designing the cutting surfaces 10 to be symmetrical to each other, the consistency and predictability of the cutting geometry parameters of the insert body 100 after each indexing are ensured. The operator does not need to make adjustments for different usage orientations, which simplifies the operation process, reduces the probability of errors, and ensures indexing accuracy and operational convenience.

[0060] As shown in Figures 1-4, in some specific embodiments, the blade body 100 is a cubic structure with six cutting surfaces 10. Any three intersecting cutting surfaces 10 constitute a cutting part, and the blade body 100 can form eight cutting parts. The blade body 100 has a centrally symmetrical structure.

[0061] The following is a detailed description of the blade body 100, using a cutting section as an example.

[0062] As shown in Figures 1 and 2, in some specific examples, the cutting part includes a first cutting surface 11, a second cutting surface 12, and a third cutting surface 13 that are adjacent to each other. The cutting edge 20 includes a first cutting edge 21, a second cutting edge 22, and a third cutting edge 23. The first cutting edge 21 is located at the intersection of the first cutting surface 11 and the second cutting surface 12. The second cutting edge 22 is located at the intersection of the first cutting surface 11 and the third cutting surface 13. The third cutting edge 23 is located at the intersection of the second cutting surface 12 and the third cutting surface 13. The first cutting edge 21, the second cutting edge 22, and the third cutting edge 23 converge at a point to form a tool tip. The first cutting surface 11, the second cutting surface 12, and the third cutting surface 13 are symmetrical to each other.

[0063] The first cutting surface 11 has a first groove 111, and the second cutting surface 12 has a second groove 121. The first groove 111 and the second groove 121 are respectively adjacent to the first cutting edge 21, and the first groove 111 and the second groove 121 extend along the extension direction of the first cutting edge 21. The first groove 111 and the second groove 121 are symmetrically arranged along the first cutting edge 21.

[0064] The first cutting surface 11 has a third groove 112, and the third cutting surface 13 has a fourth groove 131. The third groove 112 and the fourth groove 131 are adjacent to the second cutting edge 22, and the third groove 112 and the fourth groove 131 extend along the extension direction of the second cutting edge 22. The third groove 112 and the fourth groove 131 are symmetrically arranged along the second cutting edge 22.

[0065] The second cutting surface 12 has a fifth groove 122, and the third cutting surface 13 has a sixth groove 132. The fifth groove 122 and the sixth groove 132 are adjacent to the third cutting edge 23, and the fifth groove 122 and the sixth groove 132 extend along the extension direction of the third cutting edge 23. The fifth groove 122 and the sixth groove 132 are symmetrically arranged along the third cutting edge 23.

[0066] The blade body 100 is provided with a first support protrusion 113, a second support protrusion 123 and a third support protrusion 133. The first support protrusion 113 is located on the first cutting surface 11 and protrudes from the first cutting edge 21. The first support protrusion 113 has a positioning structure 1021. The second support protrusion 123 is located on the second cutting surface 12 and protrudes from the first cutting edge 21. The second support protrusion 123 has a positioning structure 1021. The third support protrusion 133 is located on the third cutting surface 13 and protrudes from the second cutting edge 22. The third support protrusion 133 has a positioning structure 1021.

[0067] The length of the first cutting surface 11 forms the length L of the insert body 100, and the width of the first cutting surface 11 forms the width W of the insert body 100. The structures of the second cutting surface 12 and the third cutting surface 13 are the same as those of the first cutting surface 11. The height of the second cutting surface 12 forms the thickness T of the insert body 100. Wherein, 4.5mm≤L≤16mm, 4.5mm≤W≤16mm, 4.5mm≤T≤16mm, and L=W=T.

[0068] The first groove 111 and the second groove 121 are configured such that when the first cutting edge 21 participates in cutting and uses different cutting surfaces 10 as the main rake face, one groove performs the chip breaking function and the other groove performs the air-blocking function.

[0069] The third groove 112 and the fourth groove 131 are configured such that when the second cutting edge 22 participates in cutting and uses a different cutting surface 10 as the main rake face, one groove functions as a chip-breaking function and the other groove functions as a clearance function.

[0070] The fifth groove 122 and the sixth groove 132 are configured such that when the third cutting edge 23 participates in cutting and uses a different cutting surface 10 as the main rake face, one groove performs the chip breaking function and the other groove performs the air-blocking function.

[0071] Therefore, by designing it as a cubic structure, it is easy to design multiple cutting surfaces 10 in a pairwise symmetrical manner, thereby ensuring the consistency and predictability of cutting geometry parameters after each indexing of the insert body 100. The operator does not need to make adjustments for different usage orientations, simplifying the operation process, reducing the probability of errors, and ensuring indexing accuracy and operational convenience.

[0072] As shown in Figure 7, the indexable cutting tool 1000 according to an embodiment of the present invention includes a cutting tool body 100 according to an embodiment of the present invention. By adopting the cutting tool body 100, grooves 101 are respectively provided on two adjacent cutting surfaces 10, so that the two grooves 101 are arranged on both sides of the cutting edge 20. The cutting tool body 100 can use the cutting surface 10 on any side of the cutting edge 20 as the main rake face for cutting by indexing. The cutting edge 20 can be used for multiple cutting flow directions, which improves the utilization rate of the cutting edge 20 and expands the applicable working conditions of the cutting tool body 100. The indexable cutting tool 1000 can dynamically change the function of the groove according to the cutting orientation. This allows a cutting edge to have complete chip breaking and anti-aircraft functions in two indexing uses, which will not increase the manufacturing cost excessively, and can solve the problems of low utilization rate and poor adaptability of traditional cutting tools, thereby improving the overall service life and economy of the tool.

[0073] Other configurations and operations of the indexable cutting tool 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0074] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
