Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and more specifically, to a triangular indexable multi-functional grooving blade. Background Technology

[0002] In the field of machining, grooving workpieces with grooving inserts is a common process.

[0003] Currently, most commercially available indexable grooving inserts are double-ended designs, typically with a single function: grooving. They cannot simultaneously machine internal holes and internal grooves, or external circles and external grooves. Furthermore, the cutting edge design results in high cutting resistance, making it difficult to achieve efficient machining through CNC program control of back-and-forth movement. For products requiring simultaneous machining of internal holes or external circles with large convex-concave differences, the insert angle design easily causes interference, necessitating manual sharpening or the use of multiple angled tools. This leads to low efficiency, cumbersome processes, difficulty in controlling product precision, and compromised quality. Therefore, this paper proposes an improved triangular indexable multi-functional grooving insert to achieve greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a triangular indexable multi-functional grooving insert. It can effectively solve the problems of single function, high cutting resistance, machining interference, and low machining efficiency of existing indexable grooving inserts. Through the triangular structure design, multiple cutting heads can be used alternately. Combined with the unique cutting edge and chip removal groove design, cutting resistance is reduced and chip removal effect is optimized. At the same time, interference during the machining process is avoided, improving the accuracy and efficiency of machining complex workpieces, reducing process flow and tool change frequency, and reducing production costs.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A triangular indexable multi-functional grooving blade includes a blade body, the blade body having a triangular structure, and a cutting head provided at each of the three ends of the blade body;

[0009] The cutting head includes a main cutting edge, a main rake face on one side of the main cutting edge, a chip removal groove on the main rake face, a main flank face on the other side of the main cutting edge, and secondary cutting edges at both ends of the main cutting edge. The secondary cutting edges are connected to the main cutting edge through a tool tip, and a secondary flank face is provided on the outer side of the secondary cutting edge. The tool tip has an arc-shaped structure of R.

[0010] Furthermore, the main cutting edge, the main flank face, the secondary cutting edge, and the secondary flank face are all provided with a cutting clearance angle.

[0011] Furthermore, the cutting edge of the main cutting edge has a V-shaped structure.

[0012] Furthermore, the blade body and the cutting head are integrally formed and are made of ultra-hard materials such as cemented carbide or metal ceramics.

[0013] Furthermore, the three main cutting edges are distributed at opposite intervals along the machining direction.

[0014] Furthermore, the chip removal groove has an arc-shaped structure.

[0015] Furthermore, each of the two sides of the blade body has a center hole for mounting or reversing positioning screw holes, and the positioning screw holes are through holes.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This design, through the triangular structure of the insert body, allows for the alternating use of the three ends of the insert, significantly extending the overall service life of the insert, reducing the frequency of insert replacements, and lowering tool consumption costs. The main cutting edge adopts a V-shaped structure with a rounded tip, which improves cutting sharpness while enhancing the impact resistance and wear resistance of the tip, effectively preventing tip breakage during cutting. The arc-shaped chip removal groove on the main rake face can quickly guide the chips out, preventing chip accumulation from affecting machining accuracy and cutting efficiency. The cutting clearance angles set on the main flank face and the secondary flank face reduce friction between the tool and the workpiece surface, lowering cutting resistance and making the machining process smoother, which helps to improve the surface finish and accuracy of the workpiece.

[0019] (2) This solution, through the design of three main cutting edges distributed at intervals in opposite directions along the machining direction, combined with the precise positioning of the positioning screw holes, enables the insert to adapt to the cutting requirements of different directions during installation and use. It can simultaneously complete multiple machining processes such as inner hole, inner groove, outer circle and outer groove, avoiding the tedious operation of frequently changing tools due to changes in machining requirements, significantly improving the machining efficiency of complex workpieces, reducing process flow time, and ensuring the consistency of product machining accuracy.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] Please see Figures 1-4 A triangular indexable multi-functional grooving blade includes a blade body 1, which has a triangular structure and a cutting head 2 is provided at each of the three ends of the blade body 1.

[0038] The cutter head 2 includes a main cutting edge 3. A main rake face 9 is provided on one side of the main cutting edge 3, and a chip removal groove 4 is provided on the main rake face 9. A main flank face 5 is provided on the other side of the main cutting edge 3. A secondary cutting edge 6 is provided at both ends of the main cutting edge 3. The secondary cutting edge 6 is connected to the main cutting edge 3 through a tool tip 7. A secondary flank face 8 is provided on the outer side of the secondary cutting edge 6. The tool tip 7 has an arc-shaped structure of R. When in use, the tool tip 7 is designed as an arc-shaped structure, which can enhance the cutting strength of the tool tip 7 and extend its service life.

[0039] See Figure 1The main cutting edge 3, the main flank face 5, the secondary cutting edge 6, and the secondary flank face 8 are all equipped with a cutting clearance angle in conjunction with the tool holder.

[0040] See Figure 1 The cutting edge of the main cutting edge 3 has a V-shaped structure.

[0041] See Figure 1 The blade body 1 and the cutting head 2 are integrally formed and are made of cemented carbide or metal ceramic. When in use, the blade body 1 and the cutting head 2 are integrally formed using ultra-hard materials such as cemented carbide or metal ceramic, which not only improves the overall rigidity and strength of the structure, but also enhances its high temperature resistance and corrosion resistance, and can meet the processing requirements of high-speed cutting and difficult-to-machine materials.

[0042] See Figure 1 The three main cutting edges 3 are distributed at opposite intervals along the machining direction, allowing them to move simultaneously and complement each other during use. This adapts to the cutting requirements in different directions and can simultaneously complete multiple machining processes such as inner holes, inner grooves, outer circles, and outer grooves. This avoids the tedious operation of frequently changing tools due to changes in machining requirements, significantly improves the machining efficiency of complex workpieces, reduces process flow time, and ensures the consistency of product machining accuracy.

[0043] See Figure 1 and Figure 2 The chip removal groove 4 has an arc-shaped structure.

[0044] See Figure 2 Both sides of the blade body 1 are provided with positive or negative mounting positioning screw holes 10, and the positioning screw holes 10 are through holes.

[0045] Working Principle: In use, the insert body 1 is first fixed to the tool holder using screws through the positioning screw holes 10, ensuring a stable and precise installation. During machining, the corresponding tool head 2 is selected according to different machining requirements. When the main cutting edge 3 of a tool head 2 becomes worn, the unworn tool head 2 can be rotated to the cutting position for continued use by rotating the insert body 1. During the cutting process, the V-shaped main cutting edge 3 contacts the workpiece first, working in conjunction with the R-shaped tool tip 7 for cutting. The secondary cutting edge 6 polishes the machined surface, reducing surface roughness. The arc-shaped chip groove 4 on the main rake face 9 promptly removes chips generated during cutting, preventing chips from entangled on the tool head 2 or workpiece and affecting machining. Simultaneously, the cutting clearance angles on the main flank face 5 and secondary flank face 8 effectively reduce friction between the tool and workpiece, lowering cutting force and temperature, making the machining process smoother, and improving machining efficiency and workpiece quality. For workpieces that require simultaneous machining of inner holes and inner grooves or outer circles and outer grooves, the three main cutting edges 3 are distributed at opposite intervals along the machining direction, allowing multiple machining operations to be completed in one clamping without frequent tool changes, thus significantly shortening machining time and improving production efficiency.
