Description

Technical Field

[0001] This invention relates to the field of quenching equipment technology, and in particular to a fastener quenching equipment. Background Technology

[0002] In order to improve mechanical properties during the production process of fasteners, fasteners are usually hardened to significantly improve their strength and hardness, thereby meeting the different usage requirements of various mechanical parts and tools.

[0003] Chinese patent CN215593131U discloses a high-strength fastener quenching and preheating device, which realizes the adjustment of the distance between the adjusting frame and the quenching component. By adjusting the turntable, the horizontal slide rail and the vertical slide rail structure, the adjusting component can easily adjust the fixed plate at multiple angles, which facilitates the quenching of fasteners at multiple angles. The overall operation is simple and convenient, which can improve the efficiency of fastener quenching.

[0004] Chinese patent CN215668097U discloses a fatigue-resistant fastener quenching device that can remove impurities from the quenching fluid without stopping normal quenching processing, thereby reducing the impurity content in the quenching fluid and ultimately reducing the frequency of quenching fluid purification. This avoids the problem of frequent quenching fluid purification affecting the normal quenching process.

[0005] During the quenching and cooling process of fasteners, the fasteners are heated by high-frequency coils. When they come into contact with the coolant, the surface of the fastener cools down instantly in a short time, causing the fastener skin to crack and producing a large amount of metal debris mixed in with the coolant used for quenching. This affects the subsequent use of the coolant. In actual use, the high-strength fastener quenching preheating device does not solve the problem of removing impurities from the quenching coolant during the fastener quenching process. Although the fatigue-resistant fastener quenching device solves the problem of removing impurities from the quenching coolant, the sedimentation method is not only slow and incomplete, but also the process of removing the settled iron filings is cumbersome.

[0006] Therefore, a fastener quenching device is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a fastener quenching apparatus to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fastener quenching device, comprising a fixed box, a liquid storage box, and a quenching box, wherein the quenching box is located on the left side of the liquid storage box and is fixedly connected to the liquid storage box, the front end of the fixed box is hinged to a door panel, and the top of the fixed box is the same size as the liquid storage box and the quenching box, the top of the fixed box is symmetrically distributed with slide rails, and the liquid storage box is slidably connected to the fixed box through the slide rails, and the upper end of the liquid storage box is hinged to a cover plate;

The sensor is connected to and controlled by the high-frequency power control box, and the inner wall of the quenching chamber is coated with a ceramic coating.

[0013] Preferably, the bottom of the inner wall of the quenching chamber is provided with a liquid inlet hole that connects to the liquid storage tank, and the liquid inlet hole has a built-in solenoid valve.

[0014] Preferably, the quenching mechanism includes a connecting rod movably connected to the middle of the sealing cover plate, and a helical gear rotatably connected to the upper end of the connecting rod. A fixed platform is fixed to the upper end face of the helical gear. The outer diameter of the helical gear is larger than the outer diameter of the fixed platform. An inclined tooth plate is embedded and fixed to the inner wall of the quenching chamber. The inclined tooth plate 41 is located below the sensor and is meshed and driven by the helical gear.

[0015] Preferably, the driving component includes an electric push rod fixed inside the fixed box at a position corresponding to the connecting rod. When the quenching box and the liquid storage box are completely aligned with the fixed box via the slide rail, the upper end of the electric push rod corresponds to the connecting rod, and an electromagnet is fixed to the upper end of the electric push rod and magnetically connected to the connecting rod. This allows the connecting rod to be lifted and pulled, enabling the connecting rod to cooperate with the fixed platform and clamping mechanism to achieve high-frequency heating and coolant quenching of the cylindrical fixed part.

[0016] Preferably, an annular electromagnet is embedded in the inner wall of the quenching chamber, and the annular electromagnet has a cylindrical structure design, with the annular electromagnet located below the sensor.

[0017] Preferably, the clamping mechanism includes a movable groove that is equidistantly spaced in a ring on the helical gear and the fixed platform. A clamping plate is movably connected in the movable groove, and the upper end of the clamping plate extends to the upper side of the fixed platform.

The other end of the spiral copper sheet is also connected to the liquid pumping end fixed in the fixed box through the connecting pipe, and the liquid pumping end is connected to the liquid storage tank through a pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This application uses an electric push rod to lift the traction connecting rod, which, in conjunction with a helical gear and a helical toothed plate, can move the cylindrical fastener placed on the fixed platform downwards and induce high-frequency heating of the fastener by the sensor under the meshing connection of the helical gear and the helical toothed plate. At the same time, it can control the rotation of the fixed platform and the cylindrical fastener, so that the fastener can be heated at high frequency in all directions.

[0022] 2. This application opens a liquid inlet between the quenching chamber and the storage tank and installs a solenoid valve. When the cylindrical fastener is subjected to high-frequency heating, the solenoid valve is controlled to open the liquid inlet, controlling the coolant in the storage tank to enter the quenching chamber. The volume of the coolant does not exceed the sensor, thus realizing the cooling and quenching work after high-frequency heating. Moreover, the coolant can be used for cooling at least twice. Then, the cooling mechanism recovers the coolant and returns it to the storage tank, solving the problem that the temperature rises after multiple uses of traditional coolant and cannot effectively meet the quenching needs of the workpiece.

[0023] 3. This application uses a cylindrical annular electromagnet inside the quenching chamber. On the one hand, it works with a clamping mechanism to fix the fixed part on the fixed platform, so that the fixed platform can better fix the fixed part to achieve rotary high-frequency heating and quenching, increase the stability of fasteners during quenching, and at the same time, it can magnetically attract metal chips generated during quenching in the coolant, reduce impurities in the coolant, and improve the coolant recycling rate.

[0035] 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.

[0036] Please see Figures 1 to 8 The present invention provides a technical solution:

[0037] A fastener quenching device includes a fixed box 3, a liquid storage tank 1, and a quenching box 2. The quenching box 2 is located on the left side of the liquid storage tank 1 and is fixedly connected to the liquid storage tank 1. The front end of the fixed box 3 is hinged to a door panel, and the top of the fixed box 3 is the same size as the liquid storage tank 1 and the quenching box 2. The top of the fixed box 3 is symmetrically fixed with slide rails 31, and the liquid storage tank 1 is slidably connected to the fixed box 3 through the slide rails 31. The upper end of the liquid storage tank 1 is hinged to a cover plate 11.

[0038] The liquid storage tank 1 contains coolant and is connected to the quenching tank 2. The quenching tank 2 is equipped with a quenching mechanism 4. The fixed box 3 is equipped with a driving component. The fixed box 3 is equipped with a cooling mechanism 6 on the rear side for cooling the coolant after workpiece quenching and returning it to the liquid storage tank 1.

[0039] The quenching mechanism 4 includes a clamping mechanism 5 for clamping and fixing the bottom of the cylindrical fastener. The clamping mechanism 5 is used to clamp the fastener for high-frequency heating and quenching cooling.

[0040] By adopting the above technical solution, this application uses an electric push rod 32 to lift the traction connecting rod 46, which, in conjunction with the helical gear 45 and the inclined tooth plate 41, allows the cylindrical fastener placed on the fixed platform 44 to move downwards and be induced by the high-frequency heating of the sensor 25 under the meshing connection of the helical gear 45 and the inclined tooth plate 41. At the same time, it can control the rotation of the fixed platform 44 and the cylindrical fastener, so that the fastener can be heated at high frequency in all directions.

[0041] Specifically, such as Figure 1 and Figure 2 , Figure 3 As shown, the quenching mechanism 4 includes a quenching cavity 21 opened on the quenching box 2, with both ends of the quenching cavity 21 being open. A sealing cover plate 23 is connected to the lower end of the quenching cavity 21, and a sealing ring is provided between the edge of the sealing cover plate 23 and the inner wall of the quenching cavity 21 to ensure a sealed state and prevent leakage of coolant into the quenching cavity 21. Three sets of ear plates 24 are fixed at equal intervals on the annular side of the sealing cover plate 23. The ear plates 24 are embedded in the bottom of the quenching box 2 and fixed with bolts. A high-frequency power control box 22 is fixed to the outside of the quenching box 2, and a sensor 25 is embedded in the inner wall of the quenching cavity 21 at a position corresponding to the high-frequency power control box 22. The sensor 25 is connected to and controlled by the high-frequency power control box 22. The inner wall of the quenching cavity 21 is coated with a ceramic coating. An inlet hole 43 is provided between the bottom of the inner wall of the quenching cavity 21 and the liquid storage tank 1, and a solenoid valve is built into the inlet hole 43.

[0042] By adopting the above technical solution, during operation, the high-frequency power control box 22 is first connected to the external power supply, and then the sensor 25 is controlled to operate. The user places the cylindrical fastener in the quenching chamber 21 and passes it through the sensor 25 to achieve high-frequency heating of the fastener. Then, the fastener is controlled to move down and contact the coolant on the lower side of the quenching chamber 21 to achieve quenching. The coolant is controlled by the solenoid valve to open and close the inlet hole 43, and the coolant in the storage tank 1 is controlled to enter the quenching chamber 21 through the inlet hole 43. Since the inner wall of the quenching chamber 21 is coated with a ceramic coating, the service life of the quenching chamber 21 can be greatly extended and heat insulation effect can be achieved.

[0043] Specifically, such as Figure 5 and Figure 4 , Figure 7 As shown, the quenching mechanism 4 includes a connecting rod 46 movably connected to the middle of the sealing cover plate 23, and a helical gear 45 rotatably connected to the upper end of the connecting rod 46. A fixed platform 44 is fixed to the upper end face of the helical gear 45, and the outer diameter of the helical gear 45 is larger than the outer diameter of the fixed platform 44. An inclined toothed plate 41 is embedded and fixed to the inner wall of the quenching chamber 21. The inclined toothed plate 41 is located below the sensor 25, and the inclined toothed plate 41 meshes with the helical gear 45 for transmission, driving... The component includes an electric push rod 32 fixed inside the fixed box 3 at a position corresponding to the connecting rod 46. When the quenching box 2 and the liquid storage box 1 are completely aligned with the fixed box 3 via the slide rail 31, the upper end of the electric push rod 32 corresponds to the connecting rod 46, and an electromagnet is fixed to the upper end of the electric push rod 32 and magnetically connected to the connecting rod 46. This allows the connecting rod 46 to lift and pull, enabling the connecting rod 46 to cooperate with the fixed platform 44 and the clamping mechanism 5 to achieve high-frequency heating and coolant quenching of the cylindrical fixed part.

[0044] By adopting the above technical solution, the fixed platform 44 in the silent state is located below the sensor 25. Then, the fastener is placed on the fixed platform 44, and the fixed platform 44 and the fastener are fixed by the clamping mechanism 5. Then, the electric push rod 32 is connected and fixed by the annular electromagnet 42 magnetically attracting the connecting rod 46. Then, the electric push rod 32 pulls the connecting rod 46 to control the fixed platform 44 to move down in the quenching chamber 21. The cylindrical fastener moves down synchronously and slowly passes the sensor 25, realizing high-frequency heating of the fastener. At the same time, due to the meshing transmission connection between the helical gear 45 on the lower side of the fixed platform 44 and the helical tooth plate 41, during the downward movement of the fixed platform 44, the helical gear 45 moves down synchronously. Under the action of meshing connection, the helical gear 45 rotates, and the fixed platform 44 realizes synchronous rotation of the fastener placed on the upper side through the clamping mechanism 5. In this way, the fastener can be fully heated at high frequency, improving the subsequent quenching effect of the fastener.

[0045] Specifically, such as Figure 3 and Figure 5 As shown, an annular electromagnet 42 is embedded in the inner wall of the quenching chamber 21, and the annular electromagnet 42 has a cylindrical structure design. The annular electromagnet 42 is located below the sensor 25.

[0046] By adopting the above technical solution, the cylindrical annular electromagnet 42 serves as the magnetic power source for the clamping mechanism 5. On the other hand, since the coolant is entirely located inside the annular electromagnet 42, the annular electromagnet 42 can effectively attract iron filings mixed in with the coolant during the subsequent quenching process of the fasteners, allowing the iron filings to adhere to the inner wall of the quenching chamber 21. This improves the effect of the coolant in the subsequent second quenching and reduces the impact on the fasteners. Furthermore, it facilitates the subsequent coolant recycling process by eliminating the step of removing iron filings and improving the efficiency of coolant recycling.

[0047] Specifically, such as Figure 4 and Figure 8 , Figure 5 As shown, the clamping mechanism 5 includes a movable groove 53 annularly and equidistantly opened on the helical gear 45 and the fixed platform 44. A clamping plate 52 is movably connected in the movable groove 53, and the upper end of the clamping plate 52 extends to the upper side of the fixed platform 44. A rack 56 is vertically connected to the lower end of the clamping plate 52. A spring 54 is provided on the upper side of the rack 56, and one end of the spring 54 is fixed to the movable groove 53, and the other end is fixed to the clamping plate 52. A gear 55 is provided in the movable groove 53 below the rack 56, and a rack 57 is provided below the gear 55. The gear 55 is rotatably connected to the inner wall of the movable groove 53 through a rotating shaft. The gear 55, rack 56, and rack 57 are meshed and connected. A metal block 51 is fixed to the lower end of the rack 57, and the metal block 51 is located below the helical gear 45 and movably connected to the helical gear 45. The metal block 51 has an isosceles triangular structure design.

[0048] By adopting the above technical solution, in order to further improve the stability of fasteners placed on the fixing platform 44 and ensure the needs of subsequent high-frequency heating and quenching processes, a clamping mechanism 5 is designed to clamp and fix cylindrical fasteners of different diameters and securely connect them to the fixing platform 44. Therefore, during use, the user places the fastener at the center of the upper end face of the fixing platform 44, at the center of the clamping plate 52. Then, as the fixing platform 44 moves downwards, the metal block 51 under the helical gear 45 moves to the annular electromagnet 42. The annular electromagnet 42 magnetically attracts the metal block 51, forcing it to move towards the annular electromagnet 42. At this time, rack 2 57 moves with the metal block 51, while rack 1 56, connected to the clamping plate 52, moves in the opposite direction under the meshing and rotation of the gear 55. Meanwhile, the clamping plate 52 is in the movable groove 53. The metal block 51 moves inward toward the fastener until it is clamped and fixed to the bottom of the outer surface of the fastener. When it is necessary to remove the clamping force on the fastener later, simply move the metal block 51 away from the position of the annular electromagnet 42. The metal block 51 loses its magnetic attraction and moves back to its original position under the action of the spring 54 in the movable groove 53. The isosceles triangular structure of the metal block 51 can increase the size of the magnetic attraction surface of the annular electromagnet 42 and increase the traction force. At the same time, the isosceles triangular structure of the metal block 51 can act as a stirring blade. When the fixed platform 44 moves down and engages with the helical gear 45 and the inclined tooth plate 41 to rotate, the metal block 51 also rotates to stir the coolant below, forcing the impurities mixed in the coolant to move in the coolant and be better attracted by the annular electromagnet 42, thereby reducing the impurity content of the coolant.

[0049] Specifically, such as Figure 6 and Figure 7 As shown, the cooling mechanism 6 includes a connecting pipe 61 on the rear side of the quenching box 2, and the connecting pipe 61 is a rubber hose. One end of the connecting pipe 61 is connected to the bottom of the quenching chamber 21, and the other end is connected to a spiral copper sheet 62. The spiral copper sheet 62 is fixed to the fixed box 3, and the spiral copper sheet 62 has a hollow structure inside. The other end of the spiral copper sheet 62 is also connected to the liquid extraction end of the liquid pump 33 fixed in the fixed box 3 through the connecting pipe 61, and the liquid delivery end of the liquid pump 33 is connected to the liquid storage tank 1 through a pipe.

[0050] By adopting the above technical solution, when the coolant in the quenching chamber 21 is used twice, or when the user installs a temperature sensor at the bottom of the quenching chamber 21 to detect the temperature in the quenching chamber 21 in real time, when the coolant temperature rises and is no longer suitable for quenching, the pump 33 is started to draw the coolant in the quenching chamber 21 through the hollow spiral copper sheet 62 and the connecting pipe 61, and deliver it to the spiral copper sheet 62 for standing. Then, the internal coolant is cooled by the heat conduction between the spiral copper sheet 62 and the outside air. When the next pump is drawn, the coolant that was cooled last time flows back to the storage tank 1 for recycling.

[0051] Working principle: During operation, the high-frequency power control box 22 is first connected to an external power source, and then the sensor 25 is controlled to operate. The user places the cylindrical fastener in the quenching chamber 21, and the fastener passes through the sensor 25 to achieve high-frequency heating. Then, the fastener is controlled to move downwards and contact the coolant on the lower side of the quenching chamber 21 to achieve quenching. The coolant is controlled by a solenoid valve to open and close the inlet hole 43, and the coolant in the storage tank 1 is controlled to enter the quenching chamber 21 through the inlet hole 43. Since the inner wall of the quenching chamber 21 is coated with a ceramic coating, it can greatly extend the service life of the quenching chamber 21 and provide heat insulation. In the static state, the fixed platform 44 is located below the sensor 25. Then, the fastener is placed on the fixed platform 44, and the fixed platform 44 is held in place by the clamping mechanism 5. 4. The fastener is fixed, and then the electric push rod 32 is connected and fixed by the magnetic attraction connecting rod 46 through the annular electromagnet 42. Then, the electric push rod 32 pulls the connecting rod 46 to control the fixed platform 44 to move down in the quenching chamber 21. The cylindrical fastener moves down synchronously and slowly passes the inductor 25 to realize high-frequency heating of the fastener. At the same time, due to the meshing transmission connection between the helical gear 45 on the lower side of the fixed platform 44 and the helical tooth plate 41, the helical gear 45 moves down synchronously during the downward movement of the fixed platform 44. Under the action of meshing connection, the helical gear 45 rotates, and the fixed platform 44 realizes synchronous rotation of the fastener placed on the upper side through the clamping mechanism 5. In this way, the fastener can be fully heated at high frequency, and the subsequent quenching effect of the fastener can be improved. The cylindrical annular electromagnet 42 serves as the clamping mechanism 5. The magnetic attraction provides power, and because the coolant is entirely located within the annular electromagnet 42, the annular electromagnet 42 can effectively attract iron filings mixed with the coolant during the subsequent quenching process of the fasteners. These iron filings adhere to the inner wall of the quenching chamber 21, improving the effect of the second quenching and reducing the impact on the fasteners. Furthermore, it facilitates subsequent coolant recycling, eliminating the need for iron filings removal and improving coolant recycling efficiency. To further enhance the stability of the fasteners on the fixing platform 44 and ensure the needs of subsequent high-frequency heating and quenching processes, a clamping mechanism 5 is designed to clamp and securely connect cylindrical fasteners of different diameters to the fixing platform 44. When the user places the fastener at the center of the upper surface of the fixed platform 44 and the center of the clamping plate 52, the metal block 51 under the helical gear 45 moves to the ring electromagnet 42. The ring electromagnet 42 magnetically attracts the metal block 51, forcing it to move towards the ring electromagnet 42. At this time, the rack 2 57 moves with the metal block 51, while the rack 1 56 connected to the clamping plate 52 moves in the opposite direction under the meshing and rotation of the gear 55. The clamping plate 52 then moves towards the fastener in the movable groove 53 until it clamps and fixes the fastener to the bottom of its outer surface. When it is necessary to remove the clamping force on the fastener later, simply move the metal block 51 away from the ring electromagnet 42, and the metal block 51 will lose its magnetic attraction.Under the action of spring 54 within the movable groove 53, the metal block 51 moves in the opposite direction to reset. The isosceles triangular metal block 51 here increases the size of the magnetic attraction surface of the annular electromagnet 42, increasing the traction force. Simultaneously, the isosceles triangular metal block 51 acts as a stirring blade. When the fixed platform 44 moves downwards and engages with the helical gear 45 and the inclined toothed plate 41, the metal block 51 also rotates, stirring the coolant below. This forces impurities in the coolant to move within the coolant and be better attracted by the annular electromagnet 42, reducing the impurity content of the coolant. When the coolant in the quenching chamber 21 is used twice, or when the user installs a temperature sensor at the bottom of the quenching chamber 21 to monitor the temperature in real time, the cooling... When the liquid temperature rises and is no longer suitable for quenching, the pump 33 is activated to draw coolant from the quenching chamber 21 through the hollow spiral copper plate 62 and connecting pipe 61. The coolant is then placed inside the spiral copper plate 62 and allowed to settle. The spiral copper plate 62 then uses heat conduction with the outside air to alternate between hot and cold, thus cooling the internal coolant. When the next pump is needed, the coolant from the previous cooling cycle flows back to the storage tank 1 for recycling. When a certain amount of magnetically attracted iron filings accumulate in the quenching chamber 21, the electromagnet at the electric push rod 32 and connecting rod 46 is de-energized. The quenching box 2 is then displaced from the fixed box 3 by sliding along the slide rail 31. The user then removes the sealing cover 23 using bolts, opens the lower opening of the quenching chamber 21, and closes the annular electromagnet 42 to clean the iron filings.
