Abstract
Description
Technical Field
[0001] This utility model relates to the field of modular forming knife technology, specifically a modular forming knife. Background Technology
[0002] A combination forming tool is a tool composed of multiple individual tools used to simultaneously or sequentially machine multiple surfaces or features of a workpiece. It is widely used in manufacturing industries such as automotive manufacturing, aerospace, mold making, and machining, for processing parts with various complex shapes, such as the machining of holes and complex contours on engine blocks, cylinder heads, crankshafts, camshafts, and other components.
[0003] A search revealed a blade-type modular forming knife with application number 202322081319.9, comprising a bushing, the side of which contacts the side of a baffle. This blade-type modular forming knife has a simple structure, is easy to use, and increases its practicality.
[0004] The combined forming cutter in the above technical solution dissipates heat solely through its own metal thermal conductivity. However, this method suffers from poor heat dissipation, resulting in the inability to dissipate the heat generated during cutting. This leads to a rapid increase in the cutter temperature, which softens the cutter material, reduces its hardness and wear resistance, and accelerates wear. Therefore, we provide a modular combined forming cutter. Utility Model Content
[0005] The purpose of this invention is to provide a modular assembly forming knife to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A modularly assembled cutting tool includes a cutting head, the cutting head having a heat dissipation hole inside, and a plurality of mounting grooves arranged in a ring on the outer peripheral end face of the heat dissipation hole, each mounting groove having a blade that can be detachably installed inside;
[0008] The blade has a blade fixing hole inside, and the mounting groove has a corresponding blade groove fixing hole inside. Blade fixing screws are detachably installed inside the blade fixing hole and the blade groove fixing hole. A handle is detachably installed at the rear end of the blade head.
[0009] As a further embodiment of this utility model: a cutter head fixing block is fixedly installed at the rear end of the first cutter head, and a cutter head fixing hole is provided inside the cutter head fixing block.
[0010] As a further improvement of this utility model: a fixing hole is provided at the front end of the first tool handle, and assembly grooves are provided on the front and rear side walls of the first tool handle.
[0011] As a further improvement of this utility model: a tool holder fixing hole is provided on the end face of the assembly groove, which passes through the tool holder and is aligned with the tool head fixing hole.
[0012] As a further improvement of this utility model: a fixing bolt is detachably installed inside the tool holder fixing hole and the tool head fixing hole, and the fixing bolt is threadedly connected to the tool holder.
[0013] As a further improvement of this utility model: the inside of the first cutter head is provided with a heat dissipation assembly groove, and the middle position of the inside of the mounting groove is connected to the heat dissipation hole through the heat dissipation assembly groove.
[0014] As a further embodiment of this utility model: a plurality of heat dissipation blocks are fixedly installed in the inner wall of the heat dissipation assembly groove, and the end of the heat dissipation block away from the heat dissipation hole is in contact with the blade.
[0015] As can be seen from the above description, the technical solution described in this application can certainly solve the technical problem that this application aims to address.
[0016] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:
[0017] This invention effectively dissipates heat to the outside through the heat dissipation holes, preventing damage to the blade and workpiece caused by high temperature. The heat dissipation assembly groove can also effectively transfer the heat generated by the friction between the blade and the workpiece to the heat dissipation holes, preventing damage to the blade and workpiece caused by high temperature. This further improves the heat dissipation effect of the device and avoids the problem that the heat generated during the cutting process cannot be dissipated in time, which would cause the tool temperature to rise sharply. High temperature will soften the tool material, reduce its hardness and wear resistance, and thus accelerate wear.
[0018] The tool holder of this utility model can effectively fix the tool head to one end of the tool holder through the mounting plane, the fixing hole, and the fixing bolt. This can improve the stability of the tool head during operation and effectively prevent the tool head from loosening. The tool head fixing block and the tool head fixing hole, through the mutual cooperation between the tool holder fixing hole and the fixing bolt, can effectively reinforce the tool head to the inner wall of the fixing hole, preventing the tool head from loosening and falling off during operation, thus avoiding inconvenience to the user and affecting the machining accuracy of the workpiece.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] Reference Figure 1 - Figure 4This utility model provides a modularly assembled cutting tool, including a cutting head 4. The cutting head 4 has a heat dissipation hole 12 inside. Multiple annularly distributed mounting grooves 8 are formed on the outer periphery of the heat dissipation hole 12. Each mounting groove 8 can be detachably fitted with a blade 9. The blade 9 has a blade fixing hole 15 inside. The mounting groove 8 has a corresponding blade groove fixing hole 10 inside. Blade fixing screws 11 are detachably installed inside the blade fixing hole 15 and the blade groove fixing hole 10. A detachable cutting handle 1 is installed at the rear end of the cutting head 4. The cutting head 4 has a heat dissipation assembly groove 16 inside. The middle position of the mounting groove 8 is connected to the heat dissipation hole 12 through the heat dissipation assembly groove 16. Multiple parallel heat dissipation blocks 13 are fixedly installed in the inner wall of the heat dissipation assembly groove 16. The end of each heat dissipation block 13 away from the heat dissipation hole 12 is in contact with the blade 9. When the cutting blade 9 is cutting, the heat sink 13 and the cutting blade 9 are in close contact, which can effectively conduct the heat generated by the cutting blade 9 and the workpiece to the heat dissipation hole 12. The heat dissipation hole 12 can effectively dissipate the heat to the outside, avoiding damage to the cutting blade 9 and the workpiece caused by high temperature. The heat dissipation assembly groove 16 can also effectively transfer the heat generated by the friction between the cutting blade 9 and the workpiece to the heat dissipation hole 12, avoiding damage to the cutting blade 9 and the workpiece caused by high temperature. This further improves the heat dissipation effect of the device and avoids the problem that the heat generated during the cutting process cannot be dissipated in time, which will cause the tool temperature to rise sharply. High temperature will soften the tool material, reduce its hardness and wear resistance, and thus accelerate wear. Example 2
[0026] In addition to all the technical features included in Embodiment 1, this embodiment also includes:
[0027] A cutting head fixing block 5 is fixedly installed at the rear end of the cutting head 4. A cutting head fixing hole 6 is provided inside the cutting head fixing block 5. A fixing hole 3 is provided at the front end of the cutting handle 1. Assembly grooves 2 are provided on the front and rear side walls of the cutting handle 1. A cutting handle fixing hole 7 is provided on the end face of the assembly groove 2, penetrating the cutting handle 1. The cutting handle fixing hole 7 and the cutting head fixing hole 6 are aligned with each other. A fixing bolt 14 is detachably installed inside the cutting handle fixing hole 7 and the cutting head fixing hole 6. The fixing bolt 14 is threadedly connected to the cutting handle 1. The cutting head 4 can be effectively fixed to one end of the cutting handle 1 through the assembly groove 2, the fixing hole 3, and the fixing bolt 14, which improves the stability of the cutting head 4 during operation. To prevent the cutting head 4 from loosening during operation, the cutting head fixing block 5 and the cutting head fixing hole 6, through the mutual cooperation between the tool holder fixing hole 7 and the fixing bolt 14, can effectively reinforce the cutting head 4 to the inner wall of the fixing hole 3, preventing the cutting head 4 from loosening and falling off during operation, thus avoiding inconvenience to the user and affecting the machining accuracy of the workpiece. The cutting head 4, together with the tool groove fixing hole 10 and the fixing bolt 14, can effectively replace the insert 9, avoiding the time wasted by replacing the entire tool. The cutting head 4, together with the tool groove fixing hole 10 and the fixing bolt 14, can fix the insert 9 and the heat sink 13 to the inner wall of the mounting groove 8, allowing the tool to effectively perform thread cutting.
[0028] Working principle: First, fix the tool holder 1 to the machine tool, then fix the tool head 4 to the rear end of the tool holder 1. To fix it to the rear of the tool holder 1, insert the tool head fixing block 5 into the fixing hole 3. At this time, the tool head fixing hole 6 coincides with the tool holder fixing hole 7 opened in the assembly slot 2. After coincidence, tighten the fixing bolt 14. This improves the stability of the tool head 4 during operation, effectively preventing loosening and avoids the tool head 4 from falling off during operation, effectively preventing inconvenience to the user and damage to the workpiece. Secondly, the tool head 4 passes through the mounting slot 8, the tool slot fixing hole 10, and... The interlocking of the blade fixing screw 11 and the blade fixing hole 15 effectively fixes the blade 9 to the bottom of the tool for effective cutting. Furthermore, the blade head 4, the tool groove fixing hole 10, and the fixing bolt 14 facilitate the replacement of the blade 9, avoiding the need to replace the entire tool and reducing the loss caused by damage to a local component that renders the entire forming tool unusable. Additionally, the heat sink 13 effectively dissipates the heat generated by the blade 9 and the workpiece into the heat dissipation hole 12, while the heat dissipation hole 12 effectively dissipates the heat to the outside, preventing damage to the blade 9 and the workpiece caused by high temperatures.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
