Description

Technical Field

[0001] This invention relates to the field of cutting tool quenching technology, specifically to a quenching device for high-nitrogen austenitic cutting tools. Background Technology

[0002] The quenching process of high-nitrogen austenitic CNC cutting tools is a key step in their manufacturing process. In actual quenching work, especially for tools with long axial dimensions, it is necessary to ensure vertical quenching and avoid deformation caused by transverse quenching. Current high-nitrogen austenitic cutting tool quenching equipment is not convenient for restricting workers to maintain vertical quenching, and tool deformation is easily caused by improper operation. At the same time, it is not convenient to automatically control the addition of water circulation to assist in energy saving during tool quenching. After the quenching work is completed, the clamping structure is prone to quenching water. Directly clamping the tool for the next batch can cause the tool holder to be directly affected by the attached water, resulting in a sudden drop in local temperature and affecting the uniformity of subsequent quenching. It is also not convenient to automatically control the auxiliary heating of the clamping structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention employs a quenching clamp that can be used in conjunction with a vertical control component to enhance the quenching quality of the cutting tool. It maintains the tool's vertical descent during quenching, ensuring symmetrical immersion in quenching water along its axis during the descent. This results in a uniform distribution of cooling stress, avoiding the preferential cooling on one side that occurs when the tool is placed horizontally. Such asymmetrical cooling can induce a thermal stress gradient, causing the tool to bend or twist. Furthermore, the invention, combined with a circulating water pump, automatically activates the circulating quenching water only during quenching, preventing accidental forgetting during manual operation and avoiding the energy-inefficient practice of constantly running the pump.

[0017] In actual tool clamping operations, the use of auxiliary heating components in conjunction with quenching clamping components allows for the preheating of the clamping plate and clamping springs via electric heating wires. This helps prevent excessive temperature differences caused by the clamping plate and clamping springs directly clamping the tool, which could lead to rapid cooling of the tool holder. Simultaneously, heating promotes moisture evaporation, ensuring that the clamping operation of tools heated to the next batch is not affected. This also prevents residual moisture on the clamping plate and clamping springs from causing localized rapid cooling of the tool during clamping, which could affect the uniformity of subsequent quenching.

[0018] The tool guide facilitates tool collection and vertical guidance through the guide cylinder. Combined with the quenching clamping component, it automatically releases the tool after the tool tip has completed quenching and hardening, ensuring the tool holder is fully immersed in the quenching water for quenching. This prevents the clamping plate from obstructing the tool holder and further affecting the quenching quality. This structure ensures that the tool tip is quenched and cooled before being released from the clamp, preventing damage to the tool tip. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 11 As shown:

[0033] This invention provides a technical solution: a high-nitrogen austenitic cutting tool quenching device, comprising a quenching water storage component 1, two vertical control components 2 installed on the quenching water storage component 1 for controlling vertical quenching; quenching clamping components 3 installed on the two vertical control components 2 for clamping the cutting tool; quenching clamping components 3 installed on the quenching clamping components 3 for clamping auxiliary heating components 4 for controlling residual water prevention; quenching clamping components 3 for pressing the vertical control components 2; a cutting tool guide component 5 installed on the quenching water storage component 1 for vertically guiding the cutting tool; the quenching water storage component 1 includes: a quenching tank 101 and pressing inclined blocks 102, two pressing inclined blocks 102 fixedly installed on the quenching tank 101, the inner side of the two pressing inclined blocks 102 being an inclined structure; water is stored inside the quenching tank 101.

[0034] The quenching water storage component 1 further includes: an air outlet pipe 103, a baffle plate 104, a water inlet pipe 105, a water outlet pipe 106, a water spray pipe 107, and a circulating water pump 108. An air outlet pipe 103 is fixedly installed on the top of the quenching tank 101, and a hot air blower is connected to the air outlet pipe 103. A baffle plate 104 is fixedly installed on the quenching tank 101; the baffle plate 104 is submerged by the quenching water inside the quenching tank 101. A water inlet pipe 105 is fixedly installed on the side of the quenching tank 101; the water inlet pipe 105 is connected to a water source. A water outlet pipe 106 is fixedly installed on the side of the quenching tank 101. Two water spray pipes 107 are fixedly installed inside the quenching tank 101, each with a row of nozzles. The bottoms of the two water spray pipes 107 are connected to flexible... A circulating water pump 108 is connected to the pipe; two circulating water pumps 108 are located at the bottom of the quenching tank 101 respectively; the vertical control component 2 includes: a guide pipe 201, a sliding column 202 and a circulation switch 203. Two guide pipes 201 are fixedly installed inside the quenching tank 101; the two guide pipes 201 pass through the baffle plate 104 respectively; a sliding column 202 is slidably sleeved inside each of the two guide pipes 201, and a spring is fixedly installed at the bottom of each of the two sliding columns 202; the springs at the bottom of the two sliding columns 202 are located inside the guide pipes 201; a circulation switch 203 is fixedly installed on each of the two sliding columns 202; the circulating water pump 108 is electrically connected to the circulation switch 203; the quenching clamping component 3 includes: a clamping fixing plate 301 and a downward moving plate 303. Shaft 3011, the clamping and fixing plate 301 has a row of grooves; two downward shafts 3011 are fixedly installed at the bottom of the clamping and fixing plate 301; the two downward shafts 3011 are slidably inserted into the two guide tubes 201 respectively; the ends of the two downward shafts 3011 are respectively pressed against the circulation switch 203. The quenching clamping component 3 can be used in conjunction with the vertical control component 2 to help improve the quenching quality of the tool. It can keep the tool from falling vertically during quenching. When falling vertically, the tool is symmetrically immersed in the quenching water along the axial direction, and the cooling stress is evenly distributed. It avoids the preferential cooling on one side caused by horizontal placement. This asymmetrical cooling will cause thermal stress gradient, resulting in bending or twisting deformation of the tool. It is more suitable for quenching tools with long axial lengths. This system can standardize staff operations and prevent tool deformation caused by lateral quenching. Simultaneously, in conjunction with the circulating water pump 108, it can automatically control the quenching water circulation to only start during quenching, avoiding the problem of excessively rapid localized heating in the quenching area due to poor water flow, thus improving quenching quality. It also allows for automatic control of the circulating water timing, preventing forgetfulness during manual operation and improving energy efficiency by avoiding the inefficiency of a constantly running circulating water pump 108. After quenching, the circulating water is automatically stopped. During actual quenching, the handle 303 is held, and the two downward-moving shafts 3011 need to be inserted into the two guide tubes 201 to ensure the tool is completely submerged in the quenching water; otherwise, it will be blocked by the baffle plate 104.

[0035] The quenching clamping component 3 further includes: clamping springs 302, handles 303, positioning switches 304, and electromagnets 305. A row of clamping springs 302 is fixedly installed on the clamping fixing plate 301, and the row of clamping springs 302 are respectively located in a row of grooves provided on the clamping fixing plate 301. Two handles 303 are fixedly installed on the clamping fixing plate 301. A positioning switch 304 is fixedly installed on the clamping fixing plate 301. An electromagnet 305 is fixedly installed on the clamping fixing plate 301. The positioning switch 304 is electrically connected to the electromagnet 305. The positioning switch 304 is aligned with the extrusion inclined block 102 on the same side. The quenching clamping component 3 also includes: a limiting plate 306 and a heating switch 307. A limiting plate 306 is fixedly installed on the clamping fixing plate 301 by bolts. Position plate 306; a heating switch 307 is fixedly installed on the clamping fixing plate 301, and the heating switch 307 is aligned with the extrusion inclined block 102 on the same side; the heating switch 307 and the positioning switch 304 are respectively used to be extruded by the extrusion inclined block 102 on the same side; the clamping auxiliary heating component 4 includes: clamping plate 401 and electric heating wire 4011, the positioning switch 304 and the heating switch 307 are externally connected to a power switch for power off when not in use for a long time; the clamping plate 401 is rotatably installed on the clamping fixing plate 301; the limiting plate 306 is used to stop the clamping plate 401; there are two electric heating wires 4011, and the two electric heating wires 4011 are respectively embedded in the clamping plate 401 and the clamping fixing plate 301; the clamping plate 401 is provided with a row of grooves; the two electric heating wires 4011 are ... Heating wire 4011 is electrically connected to heating switch 307; electromagnet 305 is magnetically attached to the end of clamping plate 401; the clamping auxiliary heating component 4 also includes: V-shaped spring 402, which is fixedly installed at the end of clamping plate 401, and the end of V-shaped spring 402 elastically fits against clamping fixing plate 301; clamping plate 401 is used to fit against tool holder clamping; in actual tool clamping work, the clamping auxiliary heating component 4, together with quenching clamping component 3, uses electric heating wire 4011 to preheat clamping plate 401 and clamping spring 302, helping to avoid the problem of excessive temperature difference and rapid cooling of tool holder position caused by clamping tool directly by clamping plate 401 and clamping spring 302, and at the same time, through heating, after the clamped tool has been quenched, The clamping plate 401 and clamping spring 302 inevitably get soaked and splashed with quenching water. The clamping plate 401 and clamping spring 302 can be automatically heated to promote water evaporation. This will not affect the clamping work after the tool is heated in the next batch. It will also prevent the tool from being rapidly cooled locally when clamped due to residual water on the clamping plate 401 and clamping spring 302, which would affect the uniformity of subsequent quenching. This structure can achieve automatic control without human operation, and further avoids forgetting. As the clamping plate 301 is inserted into the quenching tank 101, the heating switch 307 will be squeezed by the squeezing inclined block 102, and the electric heating wire 4011 will be de-energized and stop heating, so as to prevent the electric heating wire 4011 from continuing to heat while it is soaked in the quenching tank 101.

[0036] In Embodiment 2, based on Embodiment 1, the knife guide 5 includes: a lifting basket 501 and guide cylinders 502. The lifting basket 501 is slidably inserted into the baffle plate 104. The lifting basket 501 is provided with a through groove for water flow. A row of guide cylinders 502 is fixedly installed inside the lifting basket 501, and the top of each row of guide cylinders 502 has a sloping structure, and each row of guide cylinders 502 is provided with a ring of through grooves. The row of guide cylinders 502 is aligned with a row of grooves on the clamping and fixing plate 301. The knife guide 5 also includes: a handle plate 503. The handle plate 503 is fixedly installed on the lifting basket 501, and the handle plate 503 is provided with a through groove. The knife guide 5 facilitates the collection of knives and the passage of knives. The guide cylinder 502 provides vertical guidance, and in conjunction with the quenching clamping component 3, it can automatically control the release of the clamped tool after the tool tip has completed quenching and hardening, ensuring that the tool holder can also be fully immersed in the quenching water for quenching. This avoids the clamping plate 401 obstructing the tool holder, which would further affect the quenching quality of the tool holder. This structure can ensure that the clamping is released only after the tool tip has been quenched and cooled, avoiding damage to the tool tip. As the clamping fixing plate 301 is inserted into the quenching groove 101, the positioning switch 304 is pressed by the pressing inclined block 102 on the same side, controlling the electromagnet 305 to be de-energized. This can automatically control the release of the pressed tool holder. In conjunction with the vertical guidance of the guide cylinder 502, the tool is kept vertical, ensuring that the tool holder can also be fully quenched and cooled.

[0037] The working principle of this embodiment is as follows: First, after the tool is heated, the tool shank is placed on the clamping plate 301 and clamped by the clamping plate 401. The electromagnet 305 magnetically attracts the clamping plate 401 to ensure stable clamping. The clamping spring 302 can assist in elastically fitting the tool shank and improve the anti-dislodgement effect. During this process, the electric heating wire 4011 continuously heats for preheating. During actual quenching, the handle 303 is held, and the two downward moving shafts 3011 need to be inserted into the two guide tubes 201 to ensure that the tool can be completely immersed in the quenching water; otherwise, it will be... With the baffle plate 104 blocking the movement, as the lower axis 3011 moves downward, the circulation switch 203 is first squeezed due to the elastic support of the spring at the bottom of the sliding column 202. At this moment, the clamped tool just comes into contact with the quenching water, and the circulating water pump 108 also starts, spraying the quenching water at the bottom of the quenching tank 101 from the spray pipe 107, directly acting on the tool to promote the circulation and cooling of the quenching water around the tool. This automatic control prevents workers from forgetting and also improves the utilization rate of the quenching water at the bottom of the quenching tank 101. As the clamping fixing plate 301 is inserted into the quenching tank 101, it can drive... When the heating switch 307 is pressed by the inclined block 102, the heating wire 4011 is de-energized and stops heating, preventing it from continuing to heat while immersed in the quenching tank 101. As quenching completes and the tool is removed, the heating switch 307 is no longer pressed, allowing the heating wire 4011 to be energized again to promote moisture evaporation. Simultaneously, a hot air blower connected to the exhaust pipe 103 provides airflow to further aid in moisture evaporation from the clamping plate 401. This process is repeated after the next round of tool heating and quenching, improving the efficiency of small batches of tools. The manufacturing process is effective. Simultaneously, as the clamping plate 301 is inserted into the quenching tank 101, the tool will be inserted into the guide tube 502. This will cause the positioning switch 304 to be pressed by the pressing inclined block 102 on the same side, controlling the electromagnet 305 to be de-energized and no longer magnetically attracting the clamping plate 401. The V-shaped spring 402 can then elastically push the clamping plate 401 to expand outward and press the tool handle. The tool handle can fall naturally. With the vertical guidance of the guide tube 502, the tool is kept vertical, ensuring that the tool handle can also be fully quenched and cooled. Subsequently, the tool in the lifting basket 501 can be quickly removed by pulling the handle plate 503.
