[0025] like Figure 1 to Figure 2As shown, a round nose knife quenching device described in an embodiment of the utility model comprises a bottom plate 1; a quenching box 11 is fixedly connected to the top of the bottom plate 1; a vacuum pump 12 is fixedly connected to the top of the bottom plate 1; an air inlet pipe 15 is connected to the top of the vacuum pump 12; the air inlet pipe 15 is arranged close to one side of the quenching box 11; a purification box 13 is connected to the side wall of the vacuum pump 12; a storage box 14 is fixedly connected to the inner wall of the purification box 13; a first air outlet pipe 16 is connected to the side wall of the vacuum pump 12; the end of the first air outlet pipe 16 is located in the purification box 13; the top of the purification box 13 is connected to an exhaust pipe 17; during operation, when the round nose knife is quenched, the round nose knife is placed in the quenching box 11 and will come into contact with the quenching oil placed inside the quenching box 11. When the vacuum pump 12 is started to perform exhaust work, the air flow can enter the first air outlet pipe 16 from the air inlet pipe 15 and then enter the purification box 13. At this time, some of the smoke and gas generated during quenching can be sucked into the purification box 13. At the same time, a purification liquid is placed at the bottom of the purification box 13 to absorb some of the smoke and gas. When the gas floats up, it will pass through the storage box 14. At this time, the activated carbon placed in the storage box 14 can absorb the gas again and then discharge it from the exhaust pipe 17. In this step, the vacuum pump 12 is set to connect the air inlet pipe 15 and the purification box 13, so as to purify the smoke and gas generated by the round nose knife when quenching in the quenching box 11, so as to reduce the smoke and gas generated during quenching from being discharged into the air, causing environmental pollution and affecting health.

[0026] like Figures 1 to 4 As shown, the top of the bottom plate 1 is fixedly connected to a fixing frame 2; the side wall of the fixing frame 2 is fixedly connected to an electric push rod 21; the end of the electric push rod 21 is fixedly connected to a connecting rod 22; the side wall of the connecting rod 22 is fixedly connected to a motor 23; the output end of the motor 23 is fixedly connected to a bidirectional threaded rod 24; a pair of sliders 25 are connected to the screw nut pair in the middle of the bidirectional threaded rod 24; a fixing ring 26 is fixedly connected to the bottom of the slider 25; when working, when quenching the round nose cutter, the cutter is placed horizontally between the pair of fixing rings 26, and then the motor 23 is started to drive the bidirectional threaded rod 24 to rotate, which can drive the pair of sliders 25 and the fixing ring 26 to close to each other. The tool is then clamped and fixed by the fixing ring 26 at both ends of the round nose cutter, and the electric push rod 21 is then started to extend to allow the round nose cutter to enter the quenching box 11. When the quenching is completed, the electric push rod 21 is started again to contract and pull the cutter out, and the motor 23 is started to rotate in the opposite direction to release the cutter. In this step, the motor 23 is set to connect the bidirectional threaded rod 24 and the fixing ring 26, so that the cutter can be clamped and fixed during quenching to reduce the danger of holding the cutter with a handheld clamp. At the same time, when the fixing ring 26 moves at different distances, tools of different lengths can be clamped and fixed to improve the applicability of clamping and fixing.

[0027] like Figure 5As shown, the side wall of the fixing ring 26 is provided with a plurality of sliding holes 3; the side wall of the fixing ring 26 is slidably connected with a plurality of spring rods 31; the spring rods 31 slidably cooperate with the sliding holes 3; during operation, when the fixing ring 26 clamps and fixes the round nose cutter from both ends, the end of the spring rod 31 will contact the side of the cutter, at which time the spring rod 31 will be stretched under the extrusion of the cutter, and the rebound force generated by the stretching will act on the side of the cutter, clamping and fixing the cutter from the side. In this step, by setting the fixing ring 26 to connect the plurality of spring rods 31, the spring rod 31 can be clamped and fixed from the side of the cutter through the rebound generated by the stretching, so as to improve the stability of the cutter position during quenching.

[0028] like Figure 1 As shown, the top of the quenching box 11 is fixedly connected with a fixed frame 4; the side wall of the fixed frame 4 is rotatably connected with a fan blade 41; during operation, when the vacuum pump 12 drives the air inlet pipe 15 to inhale air from the quenching box 11, when the airflow flows into the air inlet pipe 15 from the opposite direction of the air inlet pipe 15, it will pass through the fan blade 41, and at this time the airflow can drive the fan blade 41 to rotate, and when the fan blade 41 rotates, the speed of the airflow flowing to the air inlet pipe 15 can be increased. In this step, by setting a fixed frame 4 connected to the fan blade 41, it can rotate with the airflow when the vacuum pump 12 drives the air inlet pipe 15 to inhale, so that the airflow can flow to the air inlet pipe 15 faster, so as to reduce the smoke and gas generated from the quenching box 11 from being dispersed.

[0029] like Figure 3 As shown, the end of the first air outlet pipe 16 is connected to the air guide pipe 5; the side wall of the air guide pipe 5 is connected to multiple second air outlet pipes 51; during operation, when smoke and gas enter the purification box 13 from the first air outlet pipe 16, they will enter the air guide pipe 5 from the first air outlet pipe 16 and then be diverted to multiple second air outlet pipes 51, and then be sprayed into the purification box 13 from the second air outlet pipes 51. In this step, the air guide pipe 5 is set to connect the first air outlet pipe 16 and the multiple second air outlet pipes 51, so as to divert the smoke and gas flowing out of the first air outlet pipe 16, increase the contact area between the smoke and gas and the purification liquid in the purification box 13, make the smoke and gas contact with the purification liquid more evenly, so as to improve the purification effect of the smoke and gas.

[0030] like Figure 1 As shown, a filter screen 6 is provided on the top of the quenching box 11; the filter screen 6 is detachably installed; during operation, before the airflow containing smoke and gas enters the air intake pipe 15, it will pass through the filter screen 6. At this time, the filter screen 6 will filter the smoke and gas, and filter out part of the smoke. After the filtering is completed, the filter screen 6 will be removed and cleaned, and then installed and reset. In this step, the filter screen 6 can be set to filter the airflow entering the air intake pipe 15, thereby reducing the smoke contained in the airflow entering the air intake pipe 15 to cause blockage, thereby affecting the absorption of gas and smoke.

[0031] like Figure 5As shown, a magnetic sheet 7 is fixedly connected to the end of the spring rod 31; during operation, when the spring rod 31 clamps and fixes the tool from the side, the magnetic sheet 7 will be adsorbed on the side of the tool. In this step, the magnetic sheet 7 is connected to the spring rod 31, which can be adsorbed on the side of the tool when the spring rod 31 clamps and fixes the tool, thereby improving the tightness of the connection between the spring rod 31 and the tool and improving the clamping and fixing effect of the tool.

[0032] Working principle: When the round nose knife is quenched, the round nose knife is placed in the quenching box 11 and contacts the quenching oil placed inside the quenching box 11. At this time, the vacuum pump 12 is started to evacuate the air, so that the airflow enters the first air outlet pipe 16 from the air inlet pipe 15 and then enters the purification box 13. At this time, part of the smoke and gas generated during quenching can be sucked into the purification box 13. At the same time, a purification liquid is placed at the bottom of the purification box 13 to absorb part of the smoke and gas. When the gas floats up, it passes through the storage box 14. At this time, the activated carbon placed in the storage box 14 can The gas is absorbed again and then discharged from the exhaust pipe 17. When quenching the round nose knife, the knife is placed horizontally between a pair of fixing rings 26, and then the motor 23 is started to drive the bidirectional threaded rod 24 to rotate, which can drive a pair of sliders 25 and the fixing ring 26 to approach each other. At this time, the fixing ring 26 will contact the two ends of the round nose knife, and the knife can be clamped and fixed from both ends. Then, the electric push rod 21 is started to extend to allow the round nose knife to enter the quenching box 11. When the quenching is completed, the electric push rod 21 is started again to contract and pull the knife out, and then the motor 23 is started to rotate in the opposite direction to loosen the knife. When the fixing ring 26 clamps and fixes the round nose cutter from both ends, the end of the spring rod 31 will contact the side of the cutter. At this time, the spring rod 31 will be stretched under the extrusion of the cutter. At the same time, the rebound force generated by the stretching acts on the side of the cutter, clamping and fixing it from the side of the cutter. When the vacuum pump 12 drives the air intake pipe 15 to inhale air from the quenching box 11, when the air flow flows from the air intake pipe 15 to the air intake pipe 15, it will pass through the fan blade 41. At this time, the air flow can drive the fan blade 41 to rotate. When the fan blade 41 rotates, the speed of the air flow to the air intake pipe 15 can be accelerated. When the smoke When dust and gas enter the purification box 13 from the first air outlet pipe 16, they will enter the air duct 5 from the first air outlet pipe 16 and then be diverted to multiple second air outlet pipes 51, and then be sprayed from the second air outlet pipes 51 into the purification box 13. Before the airflow containing smoke and gas enters the air inlet pipe 15, it will pass through the filter 6. At this time, the filter 6 will filter the smoke and gas and filter out part of the smoke. After the filtration is completed, the filter 6 will be removed and cleaned and then installed and reset. When the spring rod 31 clamps and fixes the tool from the side, the magnetic sheet 7 will be adsorbed on the side of the tool.
