Description

Technical Field

[0001] This invention relates to the field of quenching furnace equipment technology, and specifically to a fast-opening and closing aluminum alloy quenching furnace. Background Technology

[0002] Quenching furnaces are non-standard electric furnaces specially designed according to user requirements, mainly used for heat treatment such as quenching and heating of various workpieces in the aluminum industry. Aluminum alloy quenching furnaces are suitable for solution heat treatment and aging treatment of large and medium-sized aluminum alloy product parts;

[0003] Currently, in order to facilitate the rapid loading and unloading of metal parts into the quenching furnace, most quenching furnaces are equipped with quick-opening and closing furnace doors to accelerate the opening or closing of the furnace opening. This facilitates the rapid removal of the heated metal parts from the quenching furnace. However, after the metal parts have been heated, when they are removed and transferred to the quenching tank for quenching, a hoisting mechanism is required to extend into the furnace cavity to lift the metal parts out.

[0004] The following problems may occur during the process of unloading the heated metal parts:

[0005] After the metal parts have been heated, they are transferred to the quenching tank for quenching. Because the metal parts are located inside the furnace cavity, it is not convenient to fix the hoisting mechanism to the metal parts, and it is not convenient to unload and quench the metal parts. This increases the time for unloading and transferring the metal parts, affects the timeliness of quenching the metal parts, and thus reduces the quenching effect of the metal parts.

[0006] Therefore, this application proposes a rapid opening and closing aluminum alloy quenching furnace. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a rapid opening and closing aluminum alloy quenching furnace, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A rapid-opening and closing aluminum alloy quenching furnace, comprising:

[0010] Base;

[0011] The furnace body has an open top and is fixedly installed on the base. A partition ring is fixedly installed on the inner side wall of the furnace body, which divides the interior of the furnace body into an independent installation cavity and a heating cavity. The installation cavity is located below the heating cavity. A groove is opened on the inner side wall of the heating cavity, and a heating element is fixedly installed in the groove.

[0012] The placement plate is fixedly installed on the furnace body and inside the mounting cavity. The tops of the multiple guides can extend into the heating cavity. The placement plate is located inside the heating cavity and connected to the tops of the multiple guides. The outer side wall of the placement plate is in contact with the inner side wall of the heating cavity, and the bottom of the placement plate can be in contact with the top of the partition ring.

[0013] A lifting mechanism is installed in the mounting cavity and connected to the placement plate. The lifting mechanism is used to slide the placement plate along the guide or stop the sliding.

[0014] There are two cover plates, which are symmetrically hinged to the furnace body through two pivots. When the free ends of the two cover plates are in contact, the two cover plates seal the opening at the top of the furnace body.

[0015] The drive mechanism is mounted on the base and connected to both rotating shafts. The drive mechanism is used to make the two rotating shafts rotate in opposite directions or stop rotating, so as to form two cover plates to seal or unseal the opening end of the furnace body.

[0016] The transmission mechanism is mounted on the base. One end of the transmission mechanism is connected to the drive mechanism and the other end is connected to the lifting mechanism. When the two rotating shafts are rotated in opposite directions by the drive mechanism so that the two cover plates can no longer block the opening of the furnace body, the lifting mechanism is activated by the transmission mechanism so that the placement plate slides upward along the guide to the top opening of the furnace body.

[0017] Furthermore: the guide component includes a guide shell fixedly installed on the bottom wall of the mounting cavity, and a guide rod that is fixedly connected to the placement plate is vertically movably inserted through the top of the guide shell;

[0018] The drive mechanism includes a horizontally oriented rotating rod rotatably mounted on a base. A horizontally oriented rotating rod is rotatably mounted on the base. The rotating rod and the rotating rod are connected by a bevel gear assembly. The two ends of the rotating rod are respectively connected to two rotating shafts by two sets of bevel gear assemblies. The two sets of bevel gear assemblies are symmetrically arranged. A motor connected to the rotating rod is fixedly mounted on the base.

[0019] Furthermore: the lifting mechanism includes a sliding plate that is slidably installed on the bottom wall of the mounting cavity along the axis of the rotating rod. Both ends of the sliding plate are hinged to hinge rods, and the other ends of the two hinge rods are hinged to the bottom of the placement plate. A threaded rod is rotatably installed on the bottom wall of the mounting cavity. The threaded rod is threadedly connected to the sliding plate. The end of the threaded rod near the rotating rod moves through the furnace body and extends to the outside of the furnace body.

[0020] The transmission mechanism includes a rotating shaft rotatably mounted on the base. The rotating shaft and the threaded rod are located on the same axial direction. The rotating shaft and the threaded rod are fixedly connected. The rotating shaft and the rotating rod are connected by a transmission component. When the rotating rod rotates, the rotating shaft is driven to rotate synchronously through the transmission component.

[0021] Furthermore: a bracket is fixedly installed at the bottom of the placement plate, a connecting rod is vertically movably inserted through the middle of the placement plate, a connecting shaft connected to the connecting rod is rotatably installed on the bracket, a motor for driving the connecting shaft to rotate is fixedly installed at the bottom of the bracket, and an agitation mechanism that fits against the placement plate is installed at the top of the connecting rod.

[0022] Furthermore: the stirring mechanism includes a turntable fixedly connected to the top of the connecting rod. Two stirring rods, both of which are in contact with the placement plate, are fixedly installed in a ring array on the outer periphery of the turntable. The top of the stirring rod is arc-shaped, and the bottom end of the arc surface is in contact with the upper surface of the placement plate.

[0023] Furthermore: a receiving groove is provided on the top of the placement plate and outside the connecting rod. The connecting rod includes a sleeve rod, a slide rod, and an electric push rod. The sleeve rod is fixedly connected to the connecting shaft. The top of the sleeve rod is movably connected to the slide rod, which is fixedly connected to the turntable. The electric push rod is fixedly installed inside the sleeve rod and connected to the slide rod. When the slide rod is slid into the sleeve rod by the electric push rod, the turntable and the two stirring rods can be hidden in the receiving groove.

[0024] Furthermore, a sealing mechanism is installed inside the receiving tank to seal its opening end. When the turntable and the stirring rod are located outside the receiving tank, the sealing mechanism seals the opening end of the receiving tank.

[0025] Furthermore: the sealing mechanism includes an abutment shell fixedly installed in the receiving groove, an abutment rod movably passing through the abutment shell, a sealing plate fixedly connected to the end of the abutment rod and fitting against the inner side wall of the receiving groove, a spring sleeved on the outside of the abutment shell, and the two ends of the spring respectively abutting against the sealing plate and the bottom wall of the receiving groove. When the spring is in its natural state, the top of the sealing plate is flush with the top of the placement plate.

[0026] Furthermore: the outer wall of the furnace body is fixedly installed with multiple reinforcing ribs in a vertical linear array, and one of the cover plates has an installation hole that communicates with the furnace body. An automatic exhaust valve is fixedly installed on the cover plate and located in the installation hole.

[0027] This invention provides a rapid-opening and closing aluminum alloy quenching furnace. Compared with the prior art, it has the following advantages:

[0028] By incorporating a placement plate, drive mechanism, lifting mechanism, and transmission mechanism, this quenching furnace facilitates the fixing of the lifting mechanism and the metal parts during the process of transferring the metal parts to the quenching tank after heating them. This makes it easier to unload and quench the metal parts, reduces the time required for transferring the metal parts, improves the timeliness of quenching, and ultimately enhances the quenching effect.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0040] Example 1

[0041] To address the technical problems in the background section, a rapid-opening and closing aluminum alloy quenching furnace is provided as follows:

[0042] Combination Figures 1-8As shown, the present invention provides a rapid opening and closing aluminum alloy quenching furnace, comprising: a base 1; a furnace body 2, the top of which is open, the furnace body 2 being fixedly mounted on the base 1, and a partition ring 21 fixedly mounted on the inner side wall of the furnace body 2, dividing the interior of the furnace body 2 into an independent mounting cavity 22 and a heating cavity 23. The mounting cavity 22 is located below the heating cavity 23, and a groove is formed on the inner side wall of the heating cavity 23, in which a heating element is fixedly mounted. The heating element is a resistance strip made of a high-resistance alloy. Furthermore, the quenching furnace is equipped with a blower motor electrically interlocked with the heating element. The installation method of the blower motor and the electrical interlocking connection between the blower motor and the heating element are existing technologies and will not be described in detail here; The placement plate 3, on the furnace body 2 and located within the mounting cavity 22, has multiple guide members 24 fixedly installed. The tops of the multiple guide members 24 can extend into the heating cavity 23. The placement plate 3 is located within the heating cavity 23 and connected to the tops of the multiple guide members 24. The outer wall of the placement plate 3 is in contact with the inner wall of the heating cavity 23, and the bottom of the placement plate 3 can be in contact with the top of the partition ring 21; the lifting mechanism 4 is installed within the mounting cavity 22 and connected to the placement plate 3, The lifting mechanism 4 is used to slide or stop the placement plate 3 along the guide member 24; there are two cover plates 25, which are symmetrically hinged to the furnace body 2 by two rotating shafts 251. When the free ends of the two cover plates 25 are in contact, they seal the top opening of the furnace body 2. In use, the two rotating shafts 251 are rotated in opposite directions on the furnace body 2, so that the free ends of the two cover plates 25 move closer or further apart, thereby canceling or removing the seal on the top opening of the furnace body 2. The design of the two cover plates 25 accelerates the opening and closing of the furnace body 2; the drive mechanism 5 is installed... The base 1 is connected to two rotating shafts 251. The drive mechanism 5 is used to make the two rotating shafts 251 rotate in opposite directions or stop rotating, so as to form two cover plates 25 to block or unblock the opening end of the furnace body 2. The transmission mechanism 6 is installed on the base 1. One end of the transmission mechanism 6 is connected to the drive mechanism 5 and the other end is connected to the lifting mechanism 4. When the two rotating shafts 251 are rotated in opposite directions by the drive mechanism 5 so that the two cover plates 25 can unblock the opening end of the furnace body 2, the lifting mechanism 4 is activated by the transmission mechanism 6 so that the placement plate 3 slides upward along the guide 24 to the top opening of the furnace body 2.

[0043] By setting up a placement plate 3, a drive mechanism 5, a lifting mechanism 4, and a transmission mechanism 6, after the metal parts to be quenched are heated in this quenching furnace, the drive mechanism 5 causes the two rotating shafts 251 to rotate in opposite directions, driving the two cover plates 25 to rotate in opposite directions to remove the seal on the opening end of the furnace body 2. The transmission mechanism 6 then causes the lifting mechanism 4 to move, so that the placement plate 3 slides upward along the guide member 24 to the top opening of the furnace body 2, moving the heated metal parts to the outside of the furnace body 2. This avoids the situation where the metal parts are located inside the furnace cavity, which would cause inconvenience to the fixing between the hoisting mechanism and the metal parts. Therefore, after the metal parts have been heated, when they are unloaded and transferred to the quenching tank for quenching, it is convenient to fix the hoisting mechanism and the metal parts, thus facilitating the unloading and quenching of the metal parts, reducing the time for unloading and transferring the metal parts, improving the timeliness of the quenching of the metal parts, and thus improving the quenching effect of the metal parts.

[0044] Example 2

[0045] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0046] In this embodiment, the guide member 24 includes a guide shell 241 fixedly installed on the bottom wall of the mounting cavity 22. The top of the guide shell 241 has a guide rod 242 that is vertically movably inserted and fixedly connected to the placement plate 3. When the placement plate 3 is moved along the guide member 24 by the lifting mechanism 4, the movement of the placement plate 3 drives the guide rod 242 to slide along the guide shell 241, thereby achieving the guiding effect on the placement plate 3. The driving mechanism 5 includes a horizontally oriented rotating rod 51 that is rotatably installed on the base 1. A horizontally oriented rotating rod 52 is rotatably installed on the base 1. The rotating rod 51 and the rotating rod 52 are connected by bevel teeth. The first wheel assembly 53 is connected to the second wheel assembly 54. The two ends of the rotating rod 52 are connected to the two rotating shafts 251 respectively through two sets of bevel gear assemblies 54. The two sets of bevel gear assemblies 54 are symmetrically arranged. The base 1 is fixedly installed with a motor 55 connected to the rotating rod 51. When in use, the motor 55 is turned on and the output shaft of the motor 55 rotates, which drives the rotating rod 51 to rotate on the base 1. The first bevel gear assembly 53 drives the rotating rod 52 to rotate on the base 1, thereby driving the two rotating shafts 251 to rotate in opposite directions through the two sets of bevel gear assemblies 54. This causes the two cover plates 25 to rotate in opposite directions on the furnace body 2, which is convenient for control.

[0047] In this embodiment, the lifting mechanism 4 includes a sliding plate 41 slidably mounted on the bottom wall of the mounting cavity 22 along the axis of the rotating rod 51. Both ends of the sliding plate 41 are hinged to hinge rods 42, and the other ends of both hinge rods 42 are hinged to the bottom of the placement plate 3. A threaded rod 43 is rotatably mounted on the bottom wall of the mounting cavity 22. The threaded rod 43 is threadedly connected to the sliding plate 41. One end of the threaded rod 43 near the rotating rod 51 movably passes through the furnace body 2 and extends to the outside of the furnace body 2. In use, when the threaded rod 43 rotates on the furnace body 2, it drives the sliding plate 41 to slide within the mounting cavity 22. The two hinge rods 42 rotate on the sliding plate 41 around their own hinge axes, and the two hinge rods 42 also... One end of each component rotates relative to the placement plate 3, thereby causing the placement plate 3 to slide along the guide member 24. The transmission mechanism 6 includes a rotating shaft 61 rotatably mounted on the base 1. The rotating shaft 61 and the threaded rod 43 are located on the same axial direction and are fixedly connected. The rotating shaft 61 and the rotating rod 51 are connected by a transmission member 62. The transmission member 62 is a sprocket and chain transmission assembly. When the rotating rod 51 rotates, it drives the rotating shaft 61 to rotate synchronously through the transmission member 62. When the rotating rod 51 rotates on the base 1, it drives the rotating shaft 61 to rotate synchronously on the base 1 through the transmission member 62, thereby driving the threaded rod 43 to rotate synchronously.

[0048] Example 3

[0049] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0050] In this embodiment, a bracket 31 is fixedly installed at the bottom of the placement plate 3. A connecting rod 32 is vertically movably inserted through the middle of the placement plate 3. A connecting shaft 33 connected to the connecting rod 32 is rotatably installed on the bracket 31. A motor 34 for driving the connecting shaft 33 to rotate is fixedly installed at the bottom of the bracket 31. A stirring mechanism 35 that is in contact with the placement plate 3 is installed on the top of the connecting rod 32. The stirring mechanism 35 includes a turntable 351 fixedly connected to the top of the connecting rod 32. Two stirring rods 352, both in contact with the placement plate 3, are fixedly installed in a circular array on the outer side of the turntable 351. The top of the stirring rods 352 is arc-shaped, and the bottom of the arc surface is in contact with the upper surface of the placement plate 3. By setting the stirring mechanism 35, when multiple small, spherical metal parts need to be heated at one time using this quenching furnace, the connecting shaft 33 can be driven to rotate by the motor 34 to drive the connecting rods 352. 2. The turntable 351 drives the stirring rod 352 to rotate along its arc surface. When the arc surface of the stirring rod 352 contacts the spherical metal part, and the stirring rod 352 rotates continuously around the turntable 351, it can push the spherical metal part to roll on the placement plate 3, so that the contact surface between the metal part and the placement plate 3 changes, making it easier to heat the spherical metal part and thus improving the quenching efficiency of the spherical metal part. In addition, when the impurities on the surface of the metal part fall onto the placement plate 3 after the heat treatment, after the metal part is discharged, the motor 34 is turned on to drive the turntable 351 to drive the stirring rod 352 to rotate along its arc surface. The stirring rod 352 is in contact with the top of the placement plate 3, so as to achieve the scraping and cleaning effect of the waste on the top of the placement plate 3, which is beneficial to the cleaning of the waste on the top of the placement plate 3.

[0051] In this embodiment, a receiving groove 36 is provided on the top of the placement plate 3 and outside the connecting rod 32. The connecting rod 32 includes a sleeve rod 321, a sliding rod 322, and an electric actuator 323. The sleeve rod 321 is fixedly connected to the connecting shaft 33. The top of the sleeve rod 321 is movably connected to the sliding rod 322, which is fixedly connected to the turntable 351. The sliding rod 322 movably passes through the placement plate 3. The electric actuator 323 is fixedly installed inside the sleeve rod 321 and connected to the sliding rod 322. When the sliding rod 322 is slid into the sleeve rod 321 by the electric actuator 323, the turntable 351 and the two stirring rods 352 can be hidden in the receiving groove. Within 36, utilizing the design of the receiving groove 36, when the quenching furnace is needed to heat-treat the block metal parts, the connecting shaft 33 is rotated on the support 31 by the motor 34, so that the turntable 351 and the stirring rod 352 are located directly above the receiving groove 36. At this time, the electric push rod 323 is controlled to slide the slide rod 322 into the sleeve rod 321, so that the turntable 351 and the stirring rod 352 slide into the receiving groove 36 until the turntable 351 and the stirring rod 352 are both hidden in the receiving groove 36, so that the top of the placement plate 3 is flat, which is conducive to the stable placement of the block metal parts on the placement plate 3.

[0052] In this embodiment, a sealing mechanism 7 is installed in the receiving groove 36 to seal its opening end. When the turntable 351 and the stirring rod 352 are located outside the receiving groove 36, the sealing mechanism 7 seals the opening end of the receiving groove 36. By setting the sealing mechanism 7, when multiple small, spherical metal parts need to be heated at one time using this quenching furnace, the turntable 351 and the stirring rod 352 are slid to the outside of the receiving groove 36 by controlling the electric push rod 323. At this time, the sealing mechanism 7 seals the opening end of the receiving groove 36, effectively preventing small, spherical metal parts from falling into the receiving groove 36. The sealing mechanism 7 includes an abutment shell 71 fixedly installed in the receiving groove 36. An abutment rod 72 is movably inserted through the abutment shell 71. The end of the abutment rod 72 is fixedly connected to a sealing plate 73 that fits against the inner sidewall of the receiving groove 36. 3. A spring 74 is sleeved on the outside of the sliding rod 322 and the outside of the contact shell 71. The two ends of the spring 74 abut against the sealing plate 73 and the bottom wall of the receiving groove 36, respectively. When the spring 74 is in its natural state, the top of the sealing plate 73 is flush with the top of the placement plate 3. In use, when the electric push rod 323 is controlled to slide the sliding rod 322 into the sleeve rod 321, the turntable 351 and the stirring rod 352 move into the receiving groove 36, pushing the sealing plate 73 into the receiving groove 36. At this time, the contact rod 72 slides along the contact shell 71 into its interior, and the spring 74 deforms under force. When the electric push rod 323 is controlled to slide the turntable 351 and the stirring rod 352 to the outside of the receiving groove 36, the spring 74 returns to its natural state, thereby pushing the sealing plate 73 to slide towards the opening end of the receiving groove 36, thus sealing the opening end of the receiving groove 36.

[0053] In this embodiment, multiple reinforcing ribs 8 are fixedly installed in a vertical linear array on the outer wall of the furnace body 2. The design of the reinforcing ribs 8 increases the strength of the furnace body 2 and its service life. One of the cover plates 25 has an installation hole 252 that communicates with the inside of the furnace body 2. An automatic exhaust valve 9 is fixedly installed on the cover plate 25 and located in the installation hole 252. With the design of the automatic exhaust valve 9, when a metal part is placed in the furnace body 2 for heating and quenching, if there is liquid on the surface of the metal part, heating the metal part will cause the liquid on the surface of the metal part to vaporize and generate gas, thereby increasing the gas pressure inside the furnace body 2. At this time, the automatic exhaust valve 9 will automatically open to discharge the gas inside the furnace body 2, effectively preventing the furnace body 2 from cracking due to the increased gas pressure inside the furnace body 2, and improving the service life of the furnace body 2.

[0054] Working principle and usage process of this invention:

[0055] When using this quenching furnace to heat-treat bulk metal parts:

[0056] When the control motor 55 is turned on, the output shaft of the motor 55 rotates, causing the rotating rod 51 to rotate on the base 1. This, in turn, drives the rotating rod 52 to rotate on the base 1 via the first bevel gear assembly 53. The two sets of second bevel gear assemblies 54 then drive the two rotating shafts 251 to rotate in opposite directions, causing the two cover plates 25 to rotate in opposite directions on the furnace body 2, thus removing the seal on the opening end of the furnace body 2. The rotating rod 51 then rotates on the base 1, causing the rotating shaft 61 to rotate synchronously on the base 1 via the transmission component 62. This, in turn, drives the threaded rod 43 to rotate synchronously, causing the sliding plate 41 to slide within the mounting cavity 22. The two hinge rods 42 rotate on the sliding plate 41 around their own hinge axes, and the other ends of both hinge rods 42 rotate relative to the placement plate 3, causing the placement plate 3 to rotate. The slide displacement is made along the guide 24 to the top opening of the sliding furnace body 2. Then, the connecting shaft 33 is rotated on the bracket 31 by the motor 34, so that the turntable 351 and the stirring rod 352 are directly above the receiving groove 36. The electric push rod 323 is controlled to slide the sliding rod 322 into the sleeve rod 321, so that the turntable 351 and the stirring rod 352 slide into the receiving groove 36 until they are hidden in the receiving groove 36. At this time, the block metal part can be stably placed on the placement plate 3. Then, the motor 55 is controlled to turn on, so that the output shaft of the motor 55 rotates in the opposite direction, so that the placement plate 3 is reset and the two cover plates 25 seal the top opening of the furnace body 2. Then, the heating element is powered on to heat the block metal part.

[0057] When the metal part is heated, the control motor 55 is turned on. The output shaft of the motor 55 rotates, which drives the rotating rod 51 to rotate on the base 1. This causes the two cover plates 25 to rotate in opposite directions on the furnace body 2, thus removing the seal on the opening of the furnace body 2. This allows the placement plate 3 to slide along the guide 24 to the top opening of the sliding furnace body 2, which allows the heated metal block to move above the opening of the furnace body 2. This avoids the situation where the metal part is located inside the furnace cavity, which would cause inconvenience to the fixing of the hoisting mechanism and the metal part.

[0058] When multiple small, spherical metal parts need to be heated at once using this quenching furnace, the multiple small, spherical metal parts are placed on the placement plate 3 and reset. During the heating process, the electric push rod 323 is controlled to slide the turntable 351 and the stirring rod 352 to the outside of the receiving groove 36. At this time, the sealing plate 73 seals the opening of the receiving groove 36, and the motor 34 is turned on. The turntable 351 drives the stirring rod 352 to rotate along its arc surface. The arc surface of the stirring rod 352 contacts the spherical metal parts. When the stirring rod 352 rotates around the turntable 351, it can push the spherical metal parts to roll on the placement plate 3, so that the contact surface between the metal parts and the placement plate 3 changes, making it easier to heat the spherical metal parts and thus improving the quenching efficiency of spherical metal parts.

[0059] When this quenching furnace is used to heat metal parts, impurities on the surface of the metal parts will fall onto the placement plate 3 after heat treatment. After the metal parts are unloaded, the motor 34 is turned on to drive the turntable 351 to rotate the stirring rod 352 along its arc direction. The stirring rod 352 is in contact with the top of the placement plate 3, thereby achieving the scraping and cleaning effect on the top of the placement plate 3, which is beneficial for cleaning the waste on the top of the placement plate 3. The design of the reinforcing rib 8 increases the strength of the furnace body 2 and increases the service life of the furnace body 2. The design of the automatic exhaust valve 9 allows the furnace body 2 to automatically open when the metal parts are placed in the furnace body 2 for heating and quenching. When there is liquid on the surface of the metal parts, heating the metal parts will cause the liquid on the surface of the metal parts to vaporize and generate gas, thereby increasing the gas pressure inside the furnace body 2. At this time, the automatic exhaust valve 9 will automatically open to discharge the gas inside the furnace body 2, effectively preventing the furnace body 2 from cracking due to the increased gas pressure inside the furnace body 2, and improving the service life of the furnace body 2.
