Description

Technical Field

[0001] This utility model relates to the field of drill bit manufacturing technology, and more specifically, to a drill bit manufacturing quenching device. Background Technology

[0002] As an indispensable tool in industrial manufacturing, the quality of drill bits directly affects processing efficiency and product quality. In the drill bit production process, quenching is a crucial step in improving the hardness, wear resistance, and service life of the drill bit. Quenching is a heat treatment process that involves heating the drill bit to a certain temperature and then rapidly cooling it, causing a phase transformation in its internal structure, thereby increasing the material's hardness and wear resistance. This process is critical to the performance of the drill bit, as it determines its behavior in actual use.

[0003] Traditional quenching methods typically rely on manual operation or simple mechanical equipment for heating and cooling. This approach has several drawbacks. Traditional quenching methods often fail to achieve uniform heating of the drill bit, leading to inconsistent hardness and uneven internal stress distribution after quenching. This negatively impacts the drill bit's lifespan and processing quality. Furthermore, during traditional quenching, operators have direct contact with high-temperature equipment and materials, posing significant safety hazards. The high-temperature environment can easily cause burns or other accidental injuries to operators, increasing production risks. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a quenching device for drill bit production to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A drill bit production quenching device includes a support platform, a support frame connected to one side of the support platform, a turntable above the support platform, a placement groove on the turntable, a fixing mechanism inside the placement groove, the fixing mechanism including threaded rods on both sides of the placement groove, the threaded rods being connected to the placement groove via bearings, a slider being threadedly connected to the threaded rods, one side of the slider being connected to a fixing plate via a connecting plate, the fixing plate being located inside the placement groove, the connecting plate being connected through the placement groove, and one end of the threaded rod being connected to a drive mechanism.

[0007] Furthermore, the drive mechanism includes a driven bevel gear connected to one end of a threaded rod, which meshes with a driving bevel gear. The driving bevel gear is connected to a rotating rod, which is connected to a mounting plate via a bearing. The mounting plate is connected to a turntable. One end of the rotating rod is equipped with a pulley, and the two pulleys are connected by a belt drive. One end of the rotating rod is connected to a rotary motor, which is fixed to one side of the mounting plate.

[0008] Furthermore, two sets of electromagnetic heating tubes are installed below the support frame. The electromagnetic heating tubes are connected to the mounting block, the top of the mounting block is connected to the electric telescopic rod, and the electric telescopic rod is connected to the support frame.

[0009] Furthermore, the support platform is provided with an outlet, below which is a connecting channel, below which is a cooling box, and inside the cooling box is a cooling trough.

[0010] Furthermore, the cooling tank is equipped with a lifting filter plate, one side of which is connected to the connecting frame.

[0011] Furthermore, the bottom of the turntable is connected to the support platform via a rotating shaft. The rotating shaft is rotatably connected to the support platform. The bottom of the rotating shaft is connected to the drive shaft. A driven gear is connected to the drive shaft. The driven gear is connected to the driving gear. The driving gear is connected to the output end of the drive motor.

[0012] Furthermore, an encoder is installed on the drive shaft, and a fixed frame is connected to the outside of the drive motor, which is connected to the support platform.

[0013] Furthermore, a control box is installed at the bottom of the support platform.

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

[0015] (1) By setting up a fixing mechanism and a driving mechanism, the drill bit can be effectively clamped and positioned, preventing the drill bit from shifting or loosening during heating or rotation, thus improving processing stability. In addition, by setting up two sets of electromagnetic heating tubes under the support frame and adjusting the height through the mounting block and the electric telescopic rod, when the drill bit needs to be heated, the electric telescopic rod lowers the electromagnetic heating tubes to the appropriate position; while during the rotation or movement of the drill bit, it rises to avoid it, ensuring operational safety and equipment durability. The two sets of electromagnetic heating tubes perform staged heating (such as preheating and main heating), which helps to reduce internal stress of the material, avoid deformation or cracking, and improve the surface hardness and overall performance of the drill bit.

[0016] (2) By setting an outlet on the support platform and quickly transporting the heated drill bit to the cooling tank in the cooling box through the connecting channel, continuous production can be achieved. By setting a lifting filter plate and connecting frame in the cooling tank, the drill bit can be quickly pulled out of the coolant after quenching to prevent overcooling or corrosion, and at the same time facilitate subsequent removal and cleaning.

[0026] 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.

[0027] like Figures 1-5 As shown, the drill bit production quenching device according to an embodiment of this utility model includes a support platform 1, which is the basic structure of the entire device and is used to bear and support all other components. A support frame 2 is connected to one side of the support platform 1, mainly used to install and fix the electromagnetic heating tube 7 and other related components. A turntable 3 is provided above the support platform 1, and a placement groove 4 is provided on the turntable 3 for loading the drill bit to be processed. A fixing mechanism 5 is provided inside the placement groove 4. The fixing mechanism 5 includes threaded rods 501 on both sides of the placement groove 4, with opposite thread directions on the two threaded rods 501. The threaded rods 501 are connected to the placement groove 4 through bearings. A slider 502 is threadedly connected to the threaded rods 501. One side of the slider 502 is connected to a fixing plate 504 through a connecting plate 503. The fixing plate 504 directly contacts and clamps the drill bit to ensure that the drill bit remains stable during heating and rotation. The fixing plate 504 is located inside the placement groove 4. A pressure sensor is embedded in one of the fixing plates 504. The pressure sensor is electrically connected to the PLC controller inside the control box 22 and can sense... When the predetermined pressure is reached, the rotary motor 606 stops rotating. The connecting plate 503 is connected through the placement groove 4. One end of the threaded rod 501 is connected to the drive mechanism 6. The drive mechanism 6 includes a driven bevel gear 601 connected to one end of the threaded rod 501. The driven bevel gear 601 meshes with the driving bevel gear 602. The driving bevel gear 602 is connected to the rotating rod 603. The rotating rod 603 is connected to the mounting plate 604 via a bearing. The mounting plate 604 is connected to the turntable 3. One end of the rotating rod 603 is provided with a pulley 605. The pulleys 605 are connected by belt drive. One end of one of the rotating rods 603 is connected to the rotary motor 606. The rotary motor 606 is electrically connected to the external power supply through the electric slip ring and the electric slide rail on the support platform 1 to achieve rotational power supply. The rotary motor 606 is fixed to one side of the mounting plate 604. The pulleys 605 on the two rotating rods 603 are connected by belt drive, so that the power of the rotary motor 606 can be evenly distributed to each threaded rod 501, ensuring the consistency of multi-point simultaneous clamping or loosening action.

[0028] like Figures 1-6As shown, two sets of electromagnetic heating tubes 7 are installed below the support frame 2 to preheat and heat the drill bit. The electromagnetic heating tubes 7 are connected to the mounting block 8. A temperature sensor is embedded at the bottom of the mounting block 8 to monitor the temperature changes in the heating area in real time, providing data support for precise control. The top of the mounting block 8 is connected to the electric telescopic rod 9, which is connected to the support frame 2. By setting the electric telescopic rod 9, the electromagnetic heating tubes 7 can rise to avoid obstacles when the drill bit rotates and fall closer to the workpiece when heating, improving operational safety. The support platform 1 is provided with an outlet 10, and a connecting channel 11 is provided below the outlet 10. A cooling box 12 is provided below the connecting channel 11, and a cooling tank 13 is provided inside the cooling box 12 for rapid cooling. The drill bit is rapidly cooled. A lifting filter plate 14 is provided inside the cooling tank 13. One side of the lifting filter plate 14 is connected to the connecting frame 15. The cooled drill bit can be easily removed through the lifting filter plate 14. The bottom end of the turntable 3 is connected to the support platform 1 through the rotating shaft 16. The rotating shaft 16 is rotatably connected to the support platform 1. The bottom end of the rotating shaft 16 is connected to the drive shaft 17. A driven gear 18 is connected to the drive shaft 17. The driven gear 18 is connected to the driving gear 19. The driving gear 19 is connected to the output end of the drive motor 20. An encoder is provided on the drive shaft 17. A fixed frame 21 is connected to the outside of the drive motor 20. The power output by the drive motor 20 drives the rotating shaft 16 to rotate through gear transmission, thereby driving the turntable 3 to move. The encoder is used to accurately position the angular position of the turntable 3. The fixed frame 21 is connected to the support platform 1. The bottom of the support platform 1 is equipped with a control box 22. The control box 22 contains a PLC controller, which is used to control the electrical equipment in this device and is responsible for coordinating the action logic of each actuator, including heating control, clamping release, turntable 3 rotation, cooling start and stop, etc. The connecting wires in the electrical equipment on the turntable 3 all pass through the center position of the rotating shaft 16 and the drive shaft 17.

[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0030] In actual use, the operator first places the drill bit to be quenched into the placement slot 4 on the turntable 3. At this time, the fixing mechanism 5 starts working, and the rotary motor 606 starts, driving the driven bevel gear 601 to rotate through the driving bevel gear 602, thereby driving the rotating rod 603 connected to it to rotate. The rotating rod 603 transmits power to the other rotating rod 603 through the pulley 605 and belt drive structure, so that the two rotating rods 603 operate synchronously. Since the rotating rod 603 is connected to the threaded rod 501, the threaded rod 501 rotates accordingly. The threaded rod 501 is equipped with a slider 502, which is connected to the fixing plate 504 through the connecting plate 503. Since the threads on the two threaded rods 501 are in opposite directions, when the threaded rod 501 rotates, the two sliders 502 will move towards the center or away from each other, realizing the action of clamping or releasing the workpiece. The fixing plate 504 moves with the sliders 502 and finally fits against the outer wall of the drill bit to complete the clamping action. One of the fixing plates 504 has a pressure sensor embedded inside to detect whether the clamping force has reached the set value. When the pressure sensor senses the predetermined pressure, it feeds a signal back to the PLC controller in the control box 22 and automatically stops the rotating motor 606 to prevent overpressure damage to the workpiece. After clamping is completed, the drive motor 20 starts, driving the drive gear 19 to rotate, which in turn drives the driven gear 18 meshing with it, causing the drive shaft 17 to rotate and the turntable 3 to rotate. The encoder monitors the rotation angle of the turntable 3 in real time to ensure that it stops precisely at the preset angle. When the drill bit rotates to below the electromagnetic heating tube 7, the electric telescopic rod 9 moves, moving the mounting block 8 on which the electromagnetic heating tube 7 is installed down, so that the heating tube is close to the surface of the drill bit for heating. During the heating process, the temperature sensor continuously monitors the temperature change of the heating area and feeds the data back to the PLC controller. The control system automatically adjusts the power output of the electromagnetic heating tube 7 according to the set temperature to achieve precise temperature control. This device uses two sets of electromagnetic heating tubes 7 to achieve preheating and main heating of the drill bit, respectively. The preheating stage effectively reduces internal stress in the material, preventing deformation or cracking caused by sudden temperature increases. The main heating stage heats the drill bit to the required quenching temperature (e.g., 850℃~950℃) to ensure sufficient microstructure transformation. After heating, the electric telescopic rod 9 rises, lifting the electromagnetic heating tube 7 away from the drill bit position so that the turntable 3 can continue to rotate. When the heated drill bit rotates to the discharge port 10, the rotary motor 606 is activated, driving the fixing plate 504 away from the drill bit. The drill bit falls into the cooling tank 13 in the cooling box 12 through the discharge port 10 and the connecting channel 11. The cooling tank 13 is equipped with a lifting filter plate 14. After cooling, the drill bit can be lifted out of the coolant by lifting the connecting frame 15, preventing overcooling or corrosion, and facilitating subsequent removal and cleaning.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
