Description

Technical Field

[0001] This utility model relates to the field of induction hardening technology, specifically to a high-frequency induction hardening system. Background Technology

[0002] A bench vise consists of a movable jaw and a fixed jaw. The movable jaw has movable jaws mounted on it via screws, and the fixed jaw has fixed jaws mounted on it via screws. By moving the movable jaw towards the fixed jaw, the movable jaw engages with the fixed jaw to clamp the workpiece. To improve the hardness and wear resistance of the movable and fixed jaws, they are quenched. In existing technology, the jaws are placed in a salt bath furnace heated to a predetermined temperature, where they are rapidly and uniformly heated to the required quenching temperature. Once the jaws reach the appropriate temperature, they are quickly removed from the salt bath furnace and rapidly transferred to a quenching medium. Common quenching media include oil and water. In the quenching medium, the jaws cool rapidly, undergoing a phase transformation to obtain the desired microstructure and properties. However, salt bath quenching has the following disadvantages: the salt bath furnace consumes a large amount of energy during operation and produces pollutants such as waste gas and wastewater, causing a certain impact on the environment. The salt bath quenching process is relatively complex, requires manual operation, and is not suitable for automated production. Salt bath quenching generates high temperatures and waste gases, creating a poor working environment that can negatively impact workers' health. Utility Model Content

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] like Figures 1 to 9As shown, this utility model discloses a high-frequency quenching induction system, including an upper frame 1. An automatic induction quenching mechanism is provided below the upper frame 1. The automatic induction quenching mechanism includes a base frame 2, a second base frame 3, a feeding component, a positioning component, a pick-and-place component, and an induction quenching component. The feeding component is located at one end of the first base frame 2, and the positioning component is located at the other end of the first base frame 2. A conveyor belt 4 is provided on the first base frame 2. The feeding component is used to transport workpieces 25 onto the conveyor belt 4. The conveyor belt 4 is used to transport workpieces 25 to the positioning component. The positioning component is used to position the workpieces 25. The pick-and-place component is used to pick up and place the workpieces 25 from the positioning component onto the base frame. On the base frame 23, a first conveying assembly and a second conveying assembly are provided. The first conveying assembly is located on one side of the induction hardening assembly, and the second conveying assembly is located on the other side. The second conveying assembly passes through the induction hardening assembly and cooperates with the first conveying assembly to convey the workpiece 25 to the induction hardening assembly. The induction hardening assembly is connected to the upper frame 1 through an adjusting support assembly. Specifically, the induction hardening assembly is connected to a conductive connecting plate 24, which is connected to a transformer 23. The transformer 23 is mounted on the upper frame 1 through the adjusting support assembly. The induction hardening assembly is used for induction hardening of the workpiece 25, which is a magnetically conductive part. The conductive connecting plate 24 is used to support the induction hardening assembly and to supply power from the transformer 23 to the induction hardening assembly, thereby realizing the induction hardening of the workpiece 25. The adjusting support assembly is used to adjust the position of the induction hardening assembly. The adjusting support assembly adjusts the horizontal, vertical, and longitudinal positions of the induction hardening assembly using existing technology to meet the hardening requirements of parts of different sizes and improve the applicability.

[0029] The workpiece 25 is made of magnetic metal. In this embodiment, the workpiece 25 is a rectangular steel jaw, but it can also be other magnetic parts. High-frequency quenching is a metal heat treatment method, typically applicable to frequencies above 10kHz. The magnetic metal generates eddy currents under a high-frequency magnetic field, achieving rapid heating to a depth between 0.5mm and 2.5mm.

[0030] The automatic induction quenching mechanism is provided with one, two or more sets. When there are two or more sets, multiple workpieces 25 can be induction quenched at the same time, thereby improving the heat treatment efficiency of the workpieces 25.

[0031] In this embodiment, specifically, the feeding component is located on one side of the conveyor belt 4, and the other side of the conveyor belt 4 is provided with a limiting guide 10. The limiting guide 10 extends along the conveying direction of the conveyor belt 4. The conveyor belt 4 is provided with a feeding area 401. The feeding component includes a feeding box 5, a base plate 6, a drive motor 7, and a feeding push plate 8. The feeding box 5 is installed on the base plate 6, and the feeding area 401 is located between the base plate 6 and the limiting guide 10. There is at least one feeding box 5. Multiple workpieces 25 are stacked vertically inside the feeding box 5. The lower end of the feeding box 5 is provided with a discharge port. The feeding push plate 8 is slidably inserted between the feeding box 5 and the base plate 6. The output end of the drive motor 7 is connected to the feeding push plate 8 and drives the feeding push plate 8 to transport the workpieces 25 at the discharge port to the feeding area 401.

[0032] Furthermore, an elastic pressure plate 9 is provided on the side wall of the lower end of the feeding box 5. The elastic pressure plate 9 is located on the side of the feeding box 5 near the feeding area 401. The elastic pressure plate 9 is a spring sheet with a certain elasticity, which can ensure the pressing effect on the workpiece 25 and ensure that the feeding push plate 8 can push the workpiece 25 to the feeding area 401. The end of the bottom plate 6 is provided with a guide slope, which is close to the feeding area 401. The width of the guide slope is at least half the width of the workpiece 25, which ensures that sufficient support is provided to the workpiece 25 so that it can smoothly transition to the feeding area 401 of the conveyor belt 4, reducing the probability of the workpiece 25 flipping over; through An elastic pressure plate 9 is installed to press the workpiece 25, ensuring that the back of the workpiece 25 faces upwards, i.e., the flat surface of the workpiece 25 faces upwards. This facilitates the pick-and-place assembly to adsorb the workpiece 25 and ensures that the gap between the workpiece 25 and the induction hardening assembly is within the set value, thereby enabling the induction hardening assembly to perform heat treatment on the workpiece 25 normally. By pressing the workpiece 25 with the elastic pressure plate 9, it is prevented from flipping during the process of conveying the workpiece 25 from the base plate 6 to the loading area 401. If this causes the side of the workpiece 25 to face upwards, the area of ​​the workpiece 25 that the pick-and-place assembly can adsorb is smaller, which would affect the normal pick-and-place of the workpiece 25 by the pick-and-place assembly and thus affect the normal conveying of the workpiece 25.

[0033] Furthermore, a U-shaped groove is provided on the side wall of the feeding box 5 to facilitate viewing the number of workpieces 25 inside the feeding box 5, so as to add workpieces 25 in a timely manner. In this embodiment, there are four feeding boxes 5 arranged in an arrangement. The discharge port includes a current discharge port and a discharge port to be discharged. The starting position of the feeding push plate 8 is located below the discharge port to be discharged and blocks the discharge port. By effectively blocking the workpieces 25 in the discharge port to be discharged, it is ensured that only the workpieces 25 in the feeding box 5 corresponding to the current discharge port fall onto the base plate 6 each time, ensuring the normal conveying of workpieces 25.

[0034] In this embodiment, specifically, the positioning component is located on one side of the conveyor belt 4, and a limiting plate is provided on the other side of the conveyor belt 4. The positioning component includes a positioning cylinder 11 and a positioning push plate 12. The output end of the positioning cylinder 11 is connected to the positioning push plate 12 and drives the positioning push plate 12 to push the workpiece 25 to the limiting plate. By pushing the workpiece 25 to the designated position through the positioning push plate 12, the pick-and-place component can accurately pick up and place the workpiece 25, ensuring the normal transport of the workpiece 25. Furthermore, a limiting plate 2 is provided at the end of the conveyor belt 4. The limiting plate 1 and the limiting plate 2 are L-shaped as a whole. The limiting plate 2 can prevent the workpiece 25 from falling off the conveyor belt 4 and cooperates with the limiting plate 1 to further improve the positioning effect of the workpiece 25.

[0035] In this embodiment, the pick-and-place assembly includes a slide rail 13 and a pick-up cylinder 14. The slide rail 13 is located between the base frame 1 2 and the base frame 2 3. Specifically, the lower end of the slide rail 13 is connected to a support column 1 and a support column 2. The support column 1 is detachably mounted on the base frame 1 2 by bolts, and the support column 2 is detachably mounted on the base frame 2 3 by bolts. The pick-up cylinder 14 is movably mounted on the slide rail 13. The output end of the pick-up cylinder 14 is connected to a pick-up suction cup 15. The pick-up suction cup 15 is an electromagnetic suction cup or a vacuum suction cup, ensuring that the workpiece 25 is smoothly transported to the base frame 2 3.

[0036] The base frame 23 is equipped with parallel guide plates. The workpiece 25 passes between the two guide plates, which constrain the workpiece 25 to prevent it from shifting. The first conveying assembly includes a conveying push plate 16 and a conveying drive mechanism 17. The output end of the conveying drive mechanism 17 is connected to the conveying push plate 16 and drives the conveying push plate 16 to reciprocate along the base frame 23. The second conveying assembly includes a conveying push plate 28 and a conveying drive mechanism 29. The output end of the conveying drive mechanism 29 is connected to the conveying push plate 28 and drives the conveying push plate 28 to reciprocate along the base frame 23. The conveying push plate 16 and the conveying push plate 28 cooperate to clamp the workpiece 25 and convey it to the induction hardening assembly. The conveying drive mechanism 17 and the conveying drive mechanism 29 can be a motor or a cylinder. When it is a motor, the output end of the motor is connected to a threaded rod, and a slider is threaded onto the threaded rod. The conveying push plate 16 and the conveying push plate 28 are connected to the slider, thereby realizing the reciprocating movement along the base frame 23.

[0037] Furthermore, the second conveyor pusher plate 18 is L-shaped and is installed at the output end of the lifting cylinder 20. The lifting cylinder 20 drives the second conveyor pusher plate 18 to rise and fall, and is installed at the output end of the second conveyor drive mechanism 19. In use, the front end of the L-shaped second conveyor pusher plate 18 cooperates with the first conveyor pusher plate 16 to clamp the workpiece 25, ensuring the normal conveying of the workpiece 25. The rear end of the second conveyor pusher plate 18 pushes the workpiece 25 to the outlet 26, ensuring the smooth conveying of the workpiece 25.

[0038] The induction hardening assembly includes an induction heater 21 and a cooler 22, which are arranged side by side. Both the induction heater 21 and the cooler 22 are made of copper. The cooler 22 is connected to the induction heater 21 by an insulating bolt. The induction heater 21 is close to the first conveying assembly, and the cooler 22 is close to the second conveying assembly. The induction heater 21 is used to induction heat the workpiece 25, and the cooler 22 is used to cool the heated workpiece 25, thereby achieving the hardening treatment of the workpiece 25.

[0039] Specifically, the induction heater 21 includes a heating coil 2101 and a magnetic conductor 2105. The heating coil 2101 has a receiving groove 2102 at its center for the workpiece 25 to pass through. The gap between the inner sidewall of the receiving groove 2102 and the sidewall of the workpiece 25 is 1.5mm-2mm. The magnetic conductor 2105 is mounted on the heating coil 2101. The overall shape of the magnetic conductor 2105 corresponds to the shape of the heating coil 2101. Insulation gaps 2106 are provided on the sidewalls of both the heating coil 2101 and the magnetic conductor 2105. The insulation gaps 2106 are connected to the receiving groove 2102. The magnetic conductor 2105 is bonded to one side of the heating coil 2101. The magnetic conductor 2105 is made of magnetically conductive materials, such as iron, nickel, cobalt, and silicon steel sheets. The magnetic conductor 2105 plays the role of concentrating and guiding the magnetic field, making the magnetic field distribution more uniform and reasonable, and concentrating the magnetic field as evenly as possible on the workpiece 25, so that the workpiece 25 can obtain more energy and improve the effect of electromagnetic induction heating. The insulation gap 2106 plays the role of insulation and heat insulation. The width of the insulation gap 2106 is 1mm-2mm. When the insulation gap 2106 is less than 1mm, the heating coil 2101 is very easy to attract small conductive particles and iron filings under the action of the electromagnetic field, causing short circuit faults. When the insulation gap 2106 is greater than 2mm, the area of ​​the heating coil 2101 surrounding the workpiece 25 is reduced, the magnetic field range is smaller, and the heating efficiency of the workpiece 25 is affected. Moreover, when the insulation gap 2106 is too large, the magnetic field generated by the heating coil 2101 will heat other fixed parts around it, affecting the normal use of the surrounding parts.

[0040] Furthermore, the heating coil 2101 has a hollow structure. The heating coil 2101 is connected to a water inlet pipe 2103 and a water outlet pipe 2104. The water inlet pipe 2103 and the water outlet pipe 2104 are respectively connected to a water source through pipelines (not shown in the figure). Cooling water circulates in the induction heater 21 to cool the induction heater 21, preventing the induction heater 21 from deforming or melting due to excessive temperature, and ensuring the service life of the induction heater 21.

[0041] In this embodiment, the cooler 22 includes a water spray ring 2201, a second water inlet pipe 2204, and a second water outlet pipe 2205. The water spray ring 2201 has a hollow structure and is connected to the second water inlet pipe 2204 and the second water outlet pipe 2205. A receiving groove 2202 for the workpiece 25 to pass through is provided at the center of the water spray ring 2201. Multiple water spray nozzles 2203 are circumferentially arranged on the side wall of the receiving groove 2202, facing the workpiece 25. The second water inlet pipe 2204 and the second water outlet pipe 2205 are connected to a water source via pipes (not shown in the figure). The multiple water spray nozzles 2203 achieve uniform cooling of the heated workpiece 25, ensuring the uniformity of the internal structure of the workpiece 25, achieving the quenching treatment of the workpiece 25, ensuring the hardness and wear resistance of the workpiece 25, improving the service life of the workpiece 25, and also cooling the cooler 22, preventing thermal deformation of the cooler 22.

[0042] Furthermore, the water spray nozzle 2203 is inclined along the conveying direction of the workpiece 25 to cool the heated workpiece 25, reduce or avoid the spraying of cooling water onto the heated workpiece 25, thus affecting the heating effect of the workpiece 25 and ensuring the hardness and wear resistance of the workpiece 25 after quenching.

[0043] The high-frequency quenching induction system also includes a blower pipe (not shown in the figure). The air blown out by the blower pipe is used to change the direction of the cooling water sprayed from the spray nozzle 2203. Furthermore, the blowing direction of the blower pipe is the same as the conveying direction of the workpiece 25. The blower pipe and the first conveying component are located on the same side, and the blower pipe is located above and to the side of the induction heater 21. This not only achieves the function of changing the direction of the cooling water, but also avoids interference with the first conveying component and the workpiece 25. The blower pipe is a bendable metal pipe, which facilitates the adjustment of the blowing angle and prevents the cooling water from spraying onto the workpiece 25 that is being heated, thus ensuring the hardness and wear resistance of the workpiece 25 after quenching.

[0044] The working process of this utility model is as follows:

[0045] The workpiece 25 in the loading box 5 falls onto the base plate 6 through the discharge port under the action of gravity. The drive motor 7 drives the loading push plate 8 to move, pushing the workpiece 25 to the loading area 401. The conveyor belt 4 transports the workpiece 25 to the positioning component. When it reaches the positioning component, the proximity sensor transmits a signal to the control system. The control system controls the positioning cylinder 11 to work. The positioning cylinder 11 drives the positioning push plate 12 to move, pushing the workpiece 25 to the designated position. In this embodiment, the positioning push plate 12 pushes the workpiece 25 to a limit plate. The control system controls the picking component to work, that is, the picking cylinder 14 drives the picking suction cup 15 to move downward. The picking suction cup 15 picks up the workpiece 25. Then the picking cylinder 14 and the picking suction cup 15 move along the slide rail 13 to the base frame 3. When it moves above the base frame 3, the picking suction cup 15 places the workpiece 25 on the base frame 3. The first conveying... The assembly moves the workpiece 25 toward the induction hardening assembly. When it moves to a certain distance from the induction hardening assembly, this distance can be controlled by the conveying drive mechanism 17. The second conveying pusher 18 of the second conveying assembly passes through the induction hardening assembly and contacts the end of the workpiece 25. The first conveying pusher 16 and the second conveying pusher 18 clamp the two ends of the workpiece 25 and drive the workpiece 25 to continue moving toward the induction hardening assembly to perform induction hardening on the workpiece 25, ensuring the hardness of the workpiece 25 and improving its wear resistance. Through the cooperation of the first conveying pusher 16 and the second conveying pusher 18, the workpiece 25 passes through the center of the receiving groove 2102 of the induction heater 21, ensuring that the gap between each side wall of the workpiece 25 and the inner wall of the receiving groove 2102 is the same, so as to achieve uniform heating of the workpiece 25, obtain a more uniform microstructure, and ensure the consistency of the overall hardness of the workpiece 25. When workpiece 25 moves a certain distance on base frame 23, conveying drive mechanism 17 drives conveying push plate 16 back, lifting cylinder 20 drives conveying push plate 28 to move upward a certain distance, and at the same time, conveying drive mechanism 29 drives lifting cylinder 20 and conveying push plate 28 to the other end of workpiece 25, that is, the position between induction hardening component and workpiece 25. Lifting cylinder 20 drives conveying push plate 28 to move downward, so that the rear end of conveying push plate 28 contacts workpiece 25. Conveying drive mechanism 219 drives conveying push plate 28 to move workpiece 25 away from induction hardening component, and conveys workpiece 25 to outlet 26. Workpiece 25 completes induction hardening. The entire hardening process does not require human operation, which improves hardening efficiency, saves labor costs, and solves the problem of environmental pollution caused by salt bath furnace hardening.

[0046] 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.
