Description

Technical Field

[0001] This utility model relates to a double-edged PCD tool, specifically a double-edged PCD tool for metal cutting, belonging to the field of PCD tool technology. Background Technology

[0002] Most industries, including aviation, aerospace, automotive, machinery manufacturing, power, communications, construction, and home appliances, rely on metal materials for production. In these industries, there are increasingly stringent requirements for the machined surfaces of workpieces. During machining, reamers used for holes are typically four- or six-flute carbide reamers, with some employing double-flute PCD reamers.

[0003] In the prior art, such as the double-edged PCD tool for metal cutting disclosed in announcement number CN209935972U, a PCD tool head structure with two first chip removal grooves on one side is used to form a U-shaped first cutting edge, a second cutting edge, and a third cutting edge connected in sequence. The first cutting edge can be used to machine the inner wall circle of the metal part, the second cutting edge can be used to machine the bottom of the hole of the metal part, and the third cutting edge can be used to machine the outer circle of the inner boss of the metal part. This avoids the traditional step-by-step machining and significantly improves the machining efficiency.

[0004] However, in implementing the relevant technology, it was found that the above-mentioned double-edged PCD tool for metal cutting has the following problems: In the prior art, the processing efficiency is improved by the cooperation of components such as the first cutting edge, but due to the improvement of efficiency and the cutting of metal, a large amount of heat may be generated that cannot be dissipated, affecting the service life. In view of this, a double-edged PCD tool for metal cutting is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the technical problem of increased efficiency and the potential for excessive heat generation during metal cutting, which can negatively impact service life. It provides a double-edged PCD cutting tool for metal cutting.

[0006] The present invention achieves the above objectives through the following technical solution: a double-edged PCD cutting tool for metal cutting, comprising a connecting rod, a tool cylinder fixed at the bottom end of the connecting rod, and a cutting head extending from the bottom end of the tool cylinder, wherein a cooling mechanism is provided inside the tool cylinder;

[0007] The cooling mechanism includes a cooling plate, which is embedded inside one side of the blade barrel. A heat dissipation end is embedded on the outer wall of the blade barrel at the position corresponding to the cooling plate. A battery is embedded above the heat dissipation end on the outer wall of the blade barrel. A support frame is fixed on one side of the cooling plate inside the blade barrel. A contact block is fixed at one end of the blade head that penetrates the blade barrel. An air outlet is opened at the bottom of the outer wall of the blade head. A ventilation groove is opened inside the contact block.

[0008] As a further improvement of this utility model: the support frame and the contact block are closely fitted together, and a sliding structure is formed between the contact block and the support frame.

[0009] As a further improvement of this utility model: an inlet groove is provided on the other side of the outer wall of the blade cylinder, and a flow port is provided inside the inlet groove.

[0010] As a further improvement of this utility model: a mounting groove is provided at the corresponding position of the outer wall of the blade barrel and the blade head, and an installation mechanism is provided inside the mounting groove.

[0011] As a further embodiment of this utility model: the installation mechanism includes a rotating plate, which is rotatably connected inside the mounting groove, and a support shaft extends through the inner wall of one end of the mounting groove.

[0012] As a further embodiment of this utility model: the mounting mechanism further includes a collar, which is slidably connected below the heat dissipation end of the outer side of the blade barrel, and an elastic element is embedded in the mounting groove at the position of the blade head.

[0013] As a further embodiment of this utility model: the rotating plate forms a rotating structure with the mounting groove through the support shaft, and the rotating plate forms a sliding structure with the collar.

[0014] The beneficial effects of this utility model are as follows: The contact block for fixing the cutter head enters the cutter cylinder along the support frame, avoiding damage caused by contact with the cooling plate. The cooling plate is powered by a rechargeable battery and cooled by the heat dissipation end, thereby reducing the internal temperature of the cutter cylinder. When the cutter cylinder drives the cutter head to rotate, air enters the cutter cylinder through the inlet groove and the flow port. After cooling, it enters the cutter head through the ventilation groove and is discharged through the air outlet, thus allowing the cold air to circulate continuously and achieve a heat dissipation effect. The rotating plate rotates along the mounting groove via the support shaft. By adjusting the position of the collar, the rotating plate is covered and inserted into the reserved hole of the mounting groove to achieve a locking effect, which can be quickly disassembled and assembled. In conjunction with the support frame, the torque force of the contact block is increased. When disassembling, the collar is adjusted upward, and the elastic element pushes the rotating plate to reset, thereby quickly allowing the cutter head to detach from the cutter cylinder.

[0020] 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

[0021] like Figures 1 to 4 As shown, a double-edged PCD cutting tool for metal cutting includes a connecting rod 1, a tool barrel 2 fixed to the bottom end of the connecting rod 1, a cutting head 3 extending from the bottom end of the tool barrel 2, and a cooling mechanism 4 disposed inside the tool barrel 2. The cooling mechanism 4 includes a cooling plate 401, which is embedded in one side of the inside of the tool barrel 2. A heat dissipation end 402 is embedded on the outer wall of the tool barrel 2 at a position corresponding to the cooling plate 401. A battery 403 is embedded above the heat dissipation end 402 on the outer wall of the tool barrel 2. A support frame 405 is fixed to one side of the cooling plate 401 inside the tool barrel 2. A contact block 404 is fixed to one end of the cutting head 3 that penetrates into the tool barrel 2. An air outlet 407 is opened at the bottom of the outer wall of the cutting head 3. A ventilation groove 406 is opened inside the contact block 404. The support frame 405 and the... The contact block 404 fits tightly, and a sliding structure is formed between the contact block 404 and the support frame 405. An inlet groove 5 is provided on the other side of the outer wall of the cutter cylinder 2, and a flow port 6 is provided inside the inlet groove 5. The contact block 404 fixed to the cutter head 3 enters the cutter cylinder 2 along the support frame 405 to avoid damage caused by contact with the cooling plate 401. The rechargeable battery 403 provides power to the cooling plate 401 and dissipates heat to the cooling plate 401 through the heat dissipation end 402, thereby reducing the internal temperature of the cutter cylinder 2. When the cutter cylinder 2 drives the cutter head 3 to rotate, air enters the cutter cylinder 2 through the inlet groove 5 and the flow port 6. After cooling, it enters the interior of the cutter head 3 through the ventilation groove 406 and is discharged through the air outlet 407, thereby allowing the cold air to circulate continuously and achieve the heat dissipation effect. Example 2

[0022] In addition to all the technical features included in Embodiment 1, this embodiment also includes: a mounting groove 7 is provided at the corresponding positions on the outer walls of the cutter barrel 2 and the cutter head 3; an installation mechanism 8 is provided inside the mounting groove 7; the installation mechanism 8 includes a rotating plate 801, which is rotatably connected inside the mounting groove 7; a support shaft 802 extends through the inner wall of one end of the rotating plate 801 into the mounting groove 7; the installation mechanism 8 also includes a collar 803, which is slidably connected below the heat dissipation end 402 on the outside of the cutter barrel 2; an elastic element 804 is embedded in the mounting groove 7 at the position of the cutter head 3; and the rotating plate 80... 1. A rotating structure is formed between the support shaft 802 and the mounting groove 7, and a sliding structure is formed between the rotating plate 801 and the collar 803. The rotating plate 801 rotates along the mounting groove 7 via the support shaft 802. By adjusting the position of the collar 803, the rotating plate 801 is covered and inserted into the reserved hole of the mounting groove 7 to achieve a locking effect, which can be quickly disassembled and assembled. It also works with the bearing frame 405 to increase the rotational torque of the contact block 404. When disassembling, the collar 803 is adjusted upward, and the elastic element 804 elastically pushes the rotating plate 801 to reset, thereby allowing the cutter head 3 to quickly disengage from the cutter barrel 2.

[0023] Working principle: Connecting rod 1 is used to connect with the machine tool clamping end. The contact block 404 fixed to the cutter head 3 is inserted into the cutter cylinder 2 and fits against the support frame 405 to prevent damage caused by contact with the cooling plate 401 during rotation or installation. The position is adjusted by the collar 803 threaded to the cutter cylinder 2, and the rotating plate 801 is covered, allowing the rotating plate 801 to rotate in the mounting groove 7 via the support shaft 802, thereby inserting into the pre-drilled hole at the bottom of the mounting groove 7 and pressing the elastic element 804, allowing the cutter cylinder 2 and cutter head 3 to be quickly disassembled and assembled. When the cutter head 3 is damaged, it can be... The blade cylinder 2 can be replaced, and the elastic element 804 facilitates the rotation of the rotating plate 801 during disassembly and assembly, avoiding the limitation that would affect the disassembly of the blade head 3. The rechargeable battery 403 provides power to the cooling plate 401, and the cooling end 402 dissipates heat from the cooling plate 401, thereby keeping the internal temperature of the blade cylinder 2 low. During the rotation of the blade cylinder 2, air is guided into the flow port 6 through the inlet groove 5, improving the gas circulation inside the blade cylinder 2. Cold air enters the blade cylinder 2 through the ventilation groove 406 and is discharged through the air outlet 407, achieving a heat dissipation effect.
