Description

Technical Field

[0001] The present invention relates to the technical field of drill bit heat treatment, and more specifically, to a heat treatment device for drill bit production. Background Art

[0002] In the metal processing industry, drills are key cutting tools, and their quality and performance directly determine processing efficiency and product quality. In order to improve the hardness and wear resistance of the drill, it is usually necessary to perform heat treatment, among which quenching is a crucial step. The quenching process quickly cools the drill to form a martensitic structure on its surface, significantly improving its hardness and service life.

[0003] The current commonly used practice is to arrange the drill bits in order and quickly place them into a quenching barrel filled with quenching liquid after they are heated to an appropriate temperature. This step aims to utilize the rapid cooling effect of the quenching liquid to achieve rapid quenching of the drill bits. In order to improve the quenching uniformity and efficiency, the operator will also control the rotation of the drill bit in the quenching liquid through mechanical devices or manual means. This operation aims to use centrifugal force to remove impurities such as debris and oxide scale attached to the drill bit to prevent them from affecting the quenching effect and subsequent processing quality.

[0004] However, this seemingly reasonable operation method encountered a key problem in practice: the rotation of the drill bit in the quenching liquid will inevitably stir the quenching liquid, which causes eddies to form inside the quenching liquid. The generation of eddies not only increases the flow complexity of the quenching liquid, but more importantly, it causes the debris and oxide scale that were originally thrown away to be re-involved in the quenching liquid and may attach to the surface of the drill bit again. This phenomenon not only reduces the effective cooling capacity of the quenching liquid, but may also cause an uneven cooling layer on the surface of the drill bit, affecting the hardness and organizational structure after quenching, and thus affecting the overall performance and service life of the drill bit. In view of this, we propose a heat treatment device for drill bit production. Summary of the invention

[0023] The clamping mechanism includes two pairs of guide rods 9 respectively arranged at the bottom of the bearing part 7, and a guide plate 10 is arranged at the bottom of the bearing part 7. The guide plate 10 is penetrated by the guide rod 9 and is slidably connected thereto, and the guide plate 10 is penetrated by the reciprocating screw rod 8 and is fixedly connected to its own slider. A plurality of groups of clamping plates 11 are evenly arranged at the bottom of the guide plate 10, and the clamping plates 11 in the same group are symmetrically arranged, and the bottom of the clamping plates 11 are extended to form a clamping part 12 with a semicircular structure, and the bottom of the guide plate 10 is evenly fixedly connected with an adjustment ring 13 with a semicircular structure.

[0024] The feeding mechanism includes a feeding ring 14 fixedly connected to the outer wall of the base 1, the inner wall of the feeding ring 14 is detachably connected to a feeding barrel 15, the inner wall of the feeding barrel 15 is fixedly connected to a feeding plate 16, the feeding plate 16 is located in the middle of the feeding barrel 15, and the top of the feeding plate 16 is provided with evenly arranged feeding grooves 17, and the feeding grooves 17 penetrate the feeding plate 16.

[0025] The vibration mechanism includes vibration rings 18 respectively arranged at the bottom of the bearing part 7, and a plurality of springs 19 are evenly fixedly connected to the top of the vibration ring 18. The other ends of the springs 19 are fixedly connected to the bottom of the guide plate 10. A plurality of annular grooves 20 are evenly opened on the top of the vibration ring 18. Each group of clamping plates 11 is hinged in the annular grooves 20 through torsion springs. The inner wall of the vibration ring 18 extends to form symmetrically arranged vibration parts 21, and the tops of the vibration parts 21 are fixedly connected to vibration motors 22. The outer wall of the vibration ring 18 extends to form symmetrically arranged blocking parts 23.

[0026] The top of the blocking part 23 is fixedly connected with a plug column 27, the outer wall of the plug column 27 is embedded with a freely rotatable plug ring 28, the outer wall of the plug ring 28 is fixedly connected with a plurality of evenly arranged locking blocks 29, and the bottom of the guide plate 10 is provided with a lock cylinder 30 corresponding to the plug column 27, the inner wall of the lock cylinder 30 is fixedly connected with a plurality of limit members 31, and the inner wall of the lock cylinder 30 is also fixedly connected with a plurality of inclined guide members 32.

[0027] Specifically, the drill bits to be heat treated are placed in the loading barrel 15, and the drill bits are respectively inserted into the loading grooves 17 provided on the loading ring 14, and the drill bits are limited by the inner wall of the loading grooves 17, so that the drill bits are vertically upward, and then the loading barrel 15 is connected to the loading ring 14; By controlling the rotation of the reciprocating screw rod 8, the slider of the reciprocating screw rod 8 drives the guide plate 10 to move downward, and the guide plate 10 drives the vibration ring 18 to move downward together in the process. As the vibration ring 18 moves, the bottom of the vibration ring 18 contacts the top of the feeding ring 14, and the guide plate 10 is still moving downward, so that the plug column 27 moves relatively upward in the lock cylinder 30. The plug column 27 will drive the locking block 29 to move upward in the lock cylinder 30 through the plug ring 28, so that the locking block 29 contacts the guide member 32, and the locking block 29 is guided by the guide member 32, so that the locking block and the limiting member 31 are misaligned, and in this process, the semicircular structure of the adjusting ring 13 continuously limits the top of the clamping plate 11, so that the clamping plates 11 are continuously in an open state; As the reciprocating screw 8 rotates, the slider of the reciprocating screw 8 drives the guide plate 10 to move upward, and the upward movement of the guide plate 10 drives the adjusting ring 13 to move upward, so that the upward movement of the adjusting ring 13 no longer limits the clamping plate 11, and the plug post 27 is also pulled out of the lock cylinder 30. At this time, the clamping plate 11 is twisted under the torsion of its own torsion spring, thereby clamping the drill bit inside, thereby completing the clamping of the drill bit. As the guide plate 10 continues to move upward, the guide plate 10 pulls the vibration ring 18 upward and away from the feeding ring 14 through the spring 19; Subsequently, the U-shaped frame 6 is driven to rotate by the rotation of the first motor 5, so that the U-shaped frame 6 drives the reciprocating screw 8 and the guide rod 9 to rotate through the bearing portion 7, so that the guide plate 10 rotates, so that the guide plate 10 moves the drill bit to the top of the induction furnace 3. Similarly, by rotating the reciprocating screw 8 again, the drill bit can be moved into the induction furnace 3 for induction heating. After the heating is completed, similarly, the drill bit is driven away from the induction furnace 3 by the rotation of the reciprocating screw 8, and then, similarly, the drill bit enters the quenching barrel 2 to contact the quenching liquid for quenching; During the quenching process, the vibration motor 22 drives the vibration ring 18 to vibrate, so that the drill bit vibrates to shake off the oxide scale and debris. Since the drill bit vibrates to shake off the oxide scale and debris during the quenching process, the quenching liquid is not stirred, thereby preventing the oxide scale and debris from re-adhering to the drill bit; Similarly, after the drill bit is quenched, the drill bit is moved back into the loading barrel 15. It should be noted that the plug 27 will be inserted into the lock cylinder 30 again, so that the guide 32 guides the locking block 29, so that the locking block 29 rotates again to correspond to the limit member 31, so that the limit member 31 can block the locking block 29, so that the plug 27 cannot be pulled out of the lock cylinder 30. In the process again, similarly, the adjusting ring 13 guides the clamping plate 11, so that the clamping plate 11 is twisted to release the drill bit, so that the staff can remove the loading barrel 15 containing the drill bit after the heat treatment, and this cycle is repeated, thereby increasing the efficiency and convenience of heat treatment of the drill bit.

[0028] Furthermore, the inner surface of the U-shaped frame 6 is fixedly connected to a second motor 24, the top of the reciprocating screw rod 8 passes through the load-bearing portion 7 to its top and is rotationally connected thereto, the outer wall of the reciprocating screw rod 8 located at the top of the load-bearing portion 7 is fixedly connected to a single-pole flywheel 25, and the transmission directions between the single-pole flywheels 25 are oppositely set, and the main shaft of the second motor 24 is fixedly connected to a pair of sprockets 26, and the sprockets 26 rotate synchronously with the single-pole flywheels 25 through chains.

[0029] Specifically, the unipolar flywheel 25 is driven to rotate by the forward and reverse rotation of the second motor 24. Since the transmission directions of the unipolar flywheel 25 are opposite, the second motor 24 can drive the reciprocating screw 8 to rotate by the forward and reverse rotation respectively, so that the reciprocating screw 8 can control the up and down movement of the guide disk 10 on one side by its own slider, thereby realizing continuous heat treatment of the drill bit and increasing the efficiency of the heat treatment of the drill bit.

[0030] Furthermore, both sides of both ends of the locking block 29 extend toward the middle thereof, and the locking block 29 forms a diamond structure after extension, and both sides of the top of the limiting member 31 are recessed toward the middle thereof to form a groove 33 corresponding to the bottom of the locking block 29 .

[0031] Specifically, when the diamond-shaped locking block 29 moves inside the lock cylinder 30, its top can contact the guide member 32 more smoothly, so that when the guide member 32 guides it, the locking block 29 can rotate more smoothly, and the bottom of the diamond-shaped locking block 29 can engage with the groove 33 formed by the limit member 31, thereby increasing the stability when the limit member 31 and the locking block 29 abut against each other.

[0032] Furthermore, the top of the clamping plate 11 is rotatably connected to a roller 34 , and the outer wall of the roller 34 can abut against the inner wall of the adjustment ring 13 .

[0033] Specifically, by setting the roller 34, the top of the clamping plate 11 no longer directly contacts the inner wall of the adjustment ring 13, but contacts it through the roller 34, thereby increasing the smoothness of the adjustment ring 13 when adjusting the clamping plate 11, and preventing mutual wear between the two.

[0034] Furthermore, a plurality of wave-shaped abutting portions 35 are extended from opposite sides of the clamping portions 12 . The abutting portions 35 are distributed transversely, and the abutting portions 35 on two opposite clamping portions 12 are arranged in a staggered manner.

[0035] Specifically, the wave-shaped abutting portion 35 formed on the clamping portion 12 enables the clamping portion 12 to clamp the drill bit by abutting against the outer wall of the drill bit through the abutting portion 35 , and the abutting portion 35 can increase the stability of the drill bit when clamping the drill bit.

[0036] Furthermore, there is a gap between two adjacent abutting portions 35 , and the gap forms a flow channel for the quenching liquid to flow.

[0037] Specifically, the flow channel formed by the gap between the abutting portions 35 can allow the quenching liquid to flow in the flow channel, thereby increasing the contact effect between the quenching liquid and the drill bit, thereby increasing the heat treatment effect on the drill bit.

[0038] Working principle: This embodiment provides a heat treatment device for drill bit production. The drill bits to be heat treated are placed in a loading barrel 15, and the drill bits are respectively inserted into loading grooves 17 provided on a loading ring 14. The inner wall of the loading groove 17 limits the drill bits so that the drill bits are vertically upward, and then the loading barrel 15 is connected to the loading ring 14. By controlling the rotation of the reciprocating screw rod 8, the slider of the reciprocating screw rod 8 drives the guide plate 10 to move downward, and the guide plate 10 drives the vibration ring 18 to move downward together in the process. As the vibration ring 18 moves, the bottom of the vibration ring 18 contacts the top of the feeding ring 14, and the guide plate 10 is still moving downward, so that the plug column 27 moves relatively upward in the lock cylinder 30. The plug column 27 will drive the locking block 29 to move upward in the lock cylinder 30 through the plug ring 28, so that the locking block 29 contacts the guide member 32, and the locking block 29 is guided by the guide member 32, so that the locking block and the limiting member 31 are misaligned, and in this process, the semicircular structure of the adjusting ring 13 continuously limits the top of the clamping plate 11, so that the clamping plates 11 are continuously in an open state; As the reciprocating screw 8 rotates, the slider of the reciprocating screw 8 drives the guide plate 10 to move upward, and the upward movement of the guide plate 10 drives the adjusting ring 13 to move upward, so that the upward movement of the adjusting ring 13 no longer limits the clamping plate 11, and the plug post 27 is also pulled out of the lock cylinder 30. At this time, the clamping plate 11 is twisted under the torsion of its own torsion spring, thereby clamping the drill bit inside, thereby completing the clamping of the drill bit. As the guide plate 10 continues to move upward, the guide plate 10 pulls the vibration ring 18 upward and away from the feeding ring 14 through the spring 19; Subsequently, the U-shaped frame 6 is driven to rotate by the rotation of the first motor 5, so that the U-shaped frame 6 drives the reciprocating screw 8 and the guide rod 9 to rotate through the bearing portion 7, so that the guide plate 10 rotates, so that the guide plate 10 moves the drill bit to the top of the induction furnace 3. Similarly, by rotating the reciprocating screw 8 again, the drill bit can be moved into the induction furnace 3 for induction heating. After the heating is completed, similarly, the drill bit is driven away from the induction furnace 3 by the rotation of the reciprocating screw 8, and then, similarly, the drill bit enters the quenching barrel 2 to contact the quenching liquid for quenching; During the quenching process, the vibration motor 22 drives the vibration ring 18 to vibrate, so that the drill bit vibrates to shake off the oxide scale and debris. Since the drill bit vibrates to shake off the oxide scale and debris during the quenching process, the quenching liquid is not stirred, thereby preventing the oxide scale and debris from re-adhering to the drill bit; Similarly, after the drill bit is quenched, the drill bit is moved back into the loading barrel 15. It should be noted that the plug 27 will be inserted into the lock cylinder 30 again, so that the guide 32 guides the locking block 29, so that the locking block 29 rotates again to correspond to the limit member 31, so that the limit member 31 can block the locking block 29, so that the plug 27 cannot be pulled out of the lock cylinder 30. In the process again, similarly, the adjusting ring 13 guides the clamping plate 11, so that the clamping plate 11 is twisted to release the drill bit, so that the staff can remove the loading barrel 15 containing the drill bit after the heat treatment, and this cycle is repeated, thereby increasing the efficiency and convenience of heat treatment of the drill bit.
