Description

Technical Field

[0001] This invention belongs to the field of heat treatment processing technology for aluminum alloy flanges, specifically a heat treatment equipment for the production of aluminum alloy flanges. Background Technology

[0002] As a key connecting component in pipeline engineering, the flange's disc-shaped structure design is closely related to the heat treatment process. In the processing flow, the heat treatment furnace performs annealing, normalizing, quenching, and tempering on the flange through precise temperature control: Annealing can reduce hardness and refine grains, laying the foundation for subsequent machining; Normalizing can optimize the uniformity of material structure and improve comprehensive mechanical properties; Quenching and tempering significantly enhance the flange's tensile strength and toughness, making it suitable for high-pressure conditions.

[0003] Patent CN220537873U discloses a heat treatment device for aluminum alloy flanges, comprising a base, a heat treatment furnace body, a moving mechanism, a lifting mechanism, a furnace door, and a shelf mechanism. The core innovation of this solution lies in its layered shelf design, which avoids uneven heating due to flange stacking. By simultaneously lifting the support column with double push rods, the multi-layered shelf and flanges can be removed in one go, significantly improving heat treatment efficiency. The device features a plug-in rod and positioning rod connection structure, effectively preventing the positioning rod from dislodging from its slot and enhancing the stability of the shelf. Hydraulic cylinder B drives the connecting plate B to rise and fall, achieving automated material handling. This solution solves the technical pain point of traditional heat treatment devices requiring layer-by-layer removal and resulting in low efficiency, thus optimizing the heat treatment process for aluminum alloy flanges.

[0004] After the flange heat treatment is completed, the device can lift the multi-layered trays from the base plate at once using double lifting rods, facilitating transfer to the next process. However, because the trays are arranged vertically in a layered manner, there is significant spatial obstruction and structural interference between the layers. This greatly increases the design difficulty of subsequent intelligent equipment such as automated material handling, visual inspection, or robotic arm operation, making the equipment structure more complex, increasing manufacturing and maintenance costs, and restricting the feasibility of upgrading the production line to automation. Therefore, this invention provides a heat treatment device for aluminum alloy flange production. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The heat treatment equipment for aluminum alloy flange production of the present invention includes a base, on which a heat treatment furnace body is fixedly installed. Electric push rods for driving the furnace cover are installed on both sides of the port of the heat treatment furnace body. A screw is rotatably installed in the base, and the screw is screwed to a slider. A movable plate is fixedly connected to the upper end of the slider. A feeding mechanism is movably placed on the movable plate. The feeding mechanism includes a base plate, with four sets of positioning pins at the bottom of the base plate. Four sets of positioning holes are opened on the movable plate, and the positioning pins are inserted into the positioning holes. Two sets of support plates are symmetrically arranged on the base plate. Two sets of support arms are hinged on the support plates. The four sets of feeding plates are evenly distributed between the four sets of support arms. Two sets of swivel shafts are rotatably installed at both ends of the feeding plates. One end of the swivel shaft is fixedly connected to the support arm. A first worm gear is provided on one side of the lower end of the two sets of support arms. A first double worm gear meshes with the two sets of first worm gears. The feeding mechanism also includes two sets of handles, with both ends of the handles rotatably mounted on the two sets of swivel shafts. By rotating the first double worm gear component, the four sets of feeding plates are changed from a layered stacked distribution to a stepped distribution. The stepped distribution eliminates spatial obstruction and structural interference between the feeding plates, making it easier for the automatic material handling equipment to remove the aluminum alloy flange from the feeding plate. This not only reduces the design difficulty of the automatic material handling equipment, but also reduces manufacturing costs and maintenance fees.

[0007] Preferably, two sets of first sliding grooves are symmetrically opened on the base, two sets of second guide rails are symmetrically arranged at the bottom of the movable plate, the second guide rails are slidably connected to the first sliding grooves, two sets of second sliding grooves are symmetrically opened at the port of the heat treatment furnace body, and two sets of first guide rails are symmetrically arranged on the inner side of the furnace cover, the first guide rails are slidably connected to the second sliding grooves. When the electric push rod drives the furnace cover to move, the furnace cover drives the first guide rail to slide along the second slide groove, which guides the movement of the furnace cover. When the screw drives the movable plate to move through the slider, the movable plate drives the second guide rail to slide along the first slide groove, which guides the movement of the movable plate.

[0008] Preferably, the support arm includes a fixed arm, a support shaft is provided on one side of the lower end of the fixed arm, the support shaft is rotatably mounted on the support plate, a first worm gear is mounted on the end of the support shaft, a scissor-type telescopic frame is provided inside the fixed arm, a set of nodes at the lowest end of the scissor-type telescopic frame is rotatably connected to the inner wall of the fixed arm, a movable groove is opened on the fixed arm, one end of the receiving shaft passes through the movable groove and connects to a set of nodes on the scissor-type telescopic frame, guide grooves are opened on both sides of the fixed arm, the guide grooves are slidably connected to guide members, the two sets of guide members are connected by a connecting shaft, the connecting shaft passes through a set of nodes on the scissor-type telescopic frame, the feeding mechanism also includes a linkage mechanism, the linkage mechanism includes a drive mechanism, and symmetrically arranged on the drive mechanism There are two sets of lifting plates, with a limiting plate fixedly connected to the upper end of the lifting plates. Two sets of guide columns are movably inserted into the limiting plates. The guide columns are fixedly installed on the support plates. Two sets of arc-shaped grooves are opened on the limiting plates. The other end of the receiving shaft passes through the arc-shaped grooves. The driving mechanism includes a second double worm gear component, which is rotatably installed in the base plate. Two sets of second worm wheels mesh with the second double worm gear component. A fixed shaft is fixedly installed in the base plate. The second worm wheels are rotatably installed on the fixed shaft. A turntable is rotatably installed on the fixed shaft. The second worm wheel is fixedly connected to one side of the turntable. A straight groove is opened on the lifting plate. A pin is installed on the turntable. The pin is located in the straight groove. Four nodes on the cross-cut telescopic frame are respectively connected to four sets of swivel shafts. After the four sets of feeding plates are switched from a stepped distribution to a layered stacked distribution, the second double worm gear is rotated by a wrench. The second double worm gear drives the two sets of second worm wheels to rotate, and the second worm wheels drive the corresponding turntables to rotate. The rotating turntables drive the pin shaft to press against the inner wall of the straight groove, causing the lifting plate and the limiting plate to move downward. The limiting plate drives the receiving shaft to move downward through the arc groove. The receiving shaft causes the cross-scissor telescopic frame to retract through the node, thereby reducing the spacing between the four sets of feeding plates. This not only makes reasonable use of space, but also reduces the volume of the entire feeding mechanism.

[0009] The beneficial effects of this invention are as follows: 1. By rotating the first double worm gear component, the four sets of feeding plates are changed from a layered stacked distribution to a stepped distribution. The stepped distribution eliminates spatial obstruction and structural interference between the feeding plates, making it easier for the automatic material handling equipment to remove the aluminum alloy flange from the feeding plate. This not only reduces the design difficulty of the automatic material handling equipment, but also reduces manufacturing costs and maintenance fees.

[0010] 2. When the four sets of feeding plates are switched from a stepped distribution to a layered stacked distribution, the second double worm gear is rotated by a wrench. The second double worm gear drives the two sets of second worm wheels to rotate. The second worm wheels drive the corresponding turntable to rotate. The rotating turntable drives the pin shaft to press against the inner wall of the straight groove, causing the lifting plate and the limiting plate to move downward. The limiting plate drives the receiving shaft to move downward through the arc groove. The receiving shaft causes the cross-scissor telescopic frame to retract through the node, thereby reducing the spacing between the four sets of feeding plates. This not only makes reasonable use of space, but also reduces the volume of the entire feeding mechanism. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 4 As shown in the embodiment of the present invention, a heat treatment equipment for producing aluminum alloy flanges includes a base 1, on which a heat treatment furnace body 2 is fixedly installed. Electric push rods 4 for driving the furnace cover 3 are installed on both sides of the heat treatment furnace body 2. A screw 5 is rotatably installed inside the base 1, and the screw 5 is screwed to a slider 6. A movable plate 7 is fixedly connected to the upper end of the slider 6. A feeding mechanism 8 is movably placed on the movable plate 7. The feeding mechanism 8 includes a base plate 801, with four sets of positioning pins 8011 at the bottom of the base plate 801. Four sets of positioning holes 701 are opened on the movable plate 7, and the positioning pins 8011 are inserted into the positioning holes. 701, two sets of support plates 808 are symmetrically arranged on the base plate 801, and two sets of support arms 802 are hinged on the support plates 808. Four sets of feeding plates 803 are equally distributed between the four sets of support arms 802. Two sets of swivel shafts 804 are rotatably installed at both ends of the feeding plates 803. One end of the swivel shaft 804 is fixedly connected to the support arm 802. A first worm gear 806 is provided on one side of the lower end of the two sets of support arms 802. A first double worm gear 807 meshes with the two sets of first worm gears 806. The feeding mechanism 8 also includes two sets of handles 805. The two ends of the handles 805 are respectively rotatably fitted on the two sets of swivel shafts 804.

[0024] Specifically, in the initial state, four sets of feeding plates 803 are stacked layer by layer, with several sets of aluminum alloy flanges stacked on the feeding plates 803. The axis of the rotating shaft 804 on the bottom feeding plate 803 is on the same straight line as the rotation axis of the support arm 802. When heat treatment is required for the aluminum alloy flanges, the screw 5 is driven to rotate by the motor. The screw 5 drives the movable plate 7, along with the entire feeding mechanism 8, to move into the heat treatment furnace body 2 via the slider 6. After the entire feeding mechanism 8 enters the heat treatment furnace body 2, the furnace cover 3 is driven to move downward by two sets of electric push rods 4, so that the port of the heat treatment furnace body 2 is closed by the furnace cover 3. Then, the aluminum alloy flanges on the feeding mechanism 8 are heat treated by the heat treatment furnace body 2. After the heat treatment of the aluminum alloy flanges is completed, the furnace cover 3 is moved upward by the electric push rods 4, so that the port of the heat treatment furnace body 2 is opened. The screw 5 is driven to rotate again, so that the entire feeding mechanism 8 is moved out of the heat treatment furnace body 2. Then, the feeding mechanism 8 is hoisted by the lifting equipment. The two sets of handles 805 on the feeding mechanism 8 separate the positioning pin 8011 from the positioning hole 701, hoisting the feeding mechanism 8 to the next process. Then, by turning the first double worm gear 807 on the feeding mechanism 8 with a wrench, the first double worm gear 807 drives the two sets of first worm wheels 806 to rotate. The two sets of first worm wheels 806 drive the two sets of support arms 802 to rotate to one side. At the same time, the four sets of feeding plates 803 move to one side as the support arms 802 rotate, so that the four sets of feeding plates 803 are arranged in a stepped manner. The aluminum alloy flange on the feeding plate 803 is then removed by the automatic material handling equipment in the next process. Compared with the prior art, by rotating the first double worm gear 807, the four sets of feeding plates 803 are changed from a layered stacked distribution to a stepped distribution. The stepped distribution eliminates spatial obstruction and structural interference between the feeding plates 803, making it easier for the automatic material handling equipment to remove the aluminum alloy flange from the feeding plate 803. This not only reduces the design difficulty of the automatic material handling equipment, but also reduces manufacturing costs and maintenance fees.

[0025] Furthermore, two sets of first sliding grooves 101 are symmetrically opened on the base 1, and two sets of second guide rails 702 are symmetrically arranged at the bottom of the movable plate 7. The second guide rails 702 are slidably connected to the first sliding grooves 101. Two sets of second sliding grooves 201 are symmetrically opened at the port of the heat treatment furnace body 2, and two sets of first guide rails 301 are symmetrically arranged on the inner side of the furnace cover 3. The first guide rails 301 are slidably connected to the second sliding grooves 201.

[0026] Specifically, when the electric push rod 4 drives the furnace cover 3 to move, the furnace cover 3 drives the first guide rail 301 to slide along the second slide groove 201, which guides the movement of the furnace cover 3. When the screw 5 drives the movable plate 7 to move through the slider 6, the movable plate 7 drives the second guide rail 702 to slide along the first slide groove 101, which guides the movement of the movable plate 7.

[0027] Example 2: Figures 5 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the support arm 802 includes a fixed arm 8021, a support shaft 8022 is provided on one side of the lower end of the fixed arm 8021, the support shaft 8022 is rotatably mounted on the support plate 808, a first worm gear 806 is mounted on the end of the support shaft 8022, and a scissor-type telescopic frame 8023 is provided inside the fixed arm 8021. A set of nodes at the lowermost end of the scissor-type telescopic frame 8023 is rotatably connected to the inner wall of the fixed arm 8021, and is formed in the fixed arm. The movable groove 8027 on the fixed arm 8021 has one end of the receiving shaft 8028 passing through the movable groove 8027 and connecting to a set of nodes on the scissor-type telescopic frame 8023. Guide grooves 8024 are provided on both sides of the fixed arm 8021, and guide members 8025 are slidably connected to the guide grooves 8024. The two sets of guide members 8025 are connected by a connecting shaft 8026, which passes through a set of nodes on the scissor-type telescopic frame 8023. The feeding mechanism 8 also includes a linkage mechanism 809, which includes a drive... Mechanism 8091 includes two sets of lifting plates 8092 symmetrically arranged on the drive mechanism 8091. A limiting plate 8093 is fixedly connected to the upper end of the lifting plate 8092. Two sets of guide posts 8094 are movably inserted into the limiting plate 8093. The guide posts 8094 are fixedly installed on the support plate 808. Two sets of arc-shaped grooves 31 are opened on the limiting plate 8093. The other end of the receiving shaft 8028 passes through the arc-shaped grooves 31. The drive mechanism 8091 includes a second double worm gear member 11, which is rotatably mounted on the base plate 808. Inside 01, two sets of second worm gears 12 mesh with the second double worm gear component 11. The fixed shaft 13 is fixedly installed inside the base plate 801. The second worm gears 12 are rotatably installed on the fixed shaft 13. The turntable 14 is rotatably installed on the fixed shaft 13. The second worm gears 12 are fixedly connected to one side of the turntable 14. A straight groove 21 is opened on the lifting plate 8092. The pin 141 is installed on the turntable 14. The pin 141 is located in the straight groove 21. Four sets of swivel shafts 804 are respectively connected to four nodes on the cross-scissor telescopic frame 8023.

[0028] Specifically, when the four sets of feeding plates 803 are changed from a stepped distribution to a layered stacked distribution, the space between the feeding plates 803 will increase. In order to ensure that the layered stacked distribution can be smoothly switched to a stepped distribution, the aluminum alloy flanges cannot be placed on the feeding plates 803 after the space increases. The increased space not only makes the volume of the entire feeding mechanism 8 larger, but also the corresponding volume of the heat treatment furnace body 2 must also increase, thereby increasing the equipment investment cost. At the same time, the increased space cannot accommodate aluminum alloy flanges, resulting in wasted space. In the process of switching the four sets of feeding plates 803 from a layered stacked distribution to a stepped distribution, the rotating first worm gear 806 drives the support shaft 8022 and the fixed arm 8021 to rotate together. The fixed arm 8021 drives the cross-scissor telescopic frame 8023 to rotate through the cooperation of the guide member 8025 and the connecting shaft 8026. At the same time, the cross-scissor telescopic frame 8023 drives the feeding plates 803 to move, and the cross-scissor telescopic frame 8023 drives the receiving shaft 8028 to slide along the arc groove 31. Through the limiting of the arc groove 31, the length of the cross-scissor telescopic frame 8023 remains unchanged during rotation, thereby switching the four sets of feeding plates 803 from a layered stacked distribution to a stepped distribution. After the four sets of feeding plates 803 are switched from a stepped distribution to a layered stacked distribution, the second double worm gear 11 is rotated by a wrench. The second double worm gear 11 drives the two sets of second worm wheels 12 to rotate. The second worm wheels 12 drive the corresponding turntable 14 to rotate. The rotating turntable 14 drives the pin shaft 141 to press against the inner wall of the straight groove 21, causing the lifting plate 8092 and the limiting plate 8093 to move downward. The limiting plate 8093 drives the receiving shaft 8028 to move downward through the arc groove 31. The receiving shaft 8028 causes the cross-scissor telescopic frame 8023 to retract through the node, thereby reducing the spacing between the four sets of feeding plates 803. This not only makes reasonable use of space, but also reduces the volume of the entire feeding mechanism 8.

[0029] Working principle: The screw 5 is driven by a motor to rotate. The screw 5, through the slider 6, drives the movable plate 7 and the entire feeding mechanism 8 to move into the heat treatment furnace body 2. After the entire feeding mechanism 8 enters the heat treatment furnace body 2, the furnace cover 3 is driven downward by two sets of electric push rods 4, closing the port of the heat treatment furnace body 2. Then, the aluminum alloy flange on the feeding mechanism 8 is heat-treated by the heat treatment furnace body 2. After the aluminum alloy flange is heat-treated, the furnace cover 3 is moved upward by the electric push rods 4, opening the port of the heat treatment furnace body 2. The screw 5 is driven to rotate again, causing the entire feeding mechanism 8 to move out of the heat treatment furnace body. Body 2, then the two sets of handles 805 on the feeding mechanism 8 are hung by the lifting equipment to separate the positioning pin 8011 from the positioning hole 701, and the feeding mechanism 8 is hoisted to the next process. Then, the first double worm gear 807 on the feeding mechanism 8 is rotated by the wrench. The first double worm gear 807 drives the two sets of first worm wheels 806 to rotate. The two sets of first worm wheels 806 drive the two sets of support arms 802 to rotate to one side. At the same time, the four sets of feeding plates 803 move to one side with the rotation of the support arms 802, so that the four sets of feeding plates 803 are distributed in a stepped manner. Then, the aluminum alloy flange on the feeding plate 803 is removed by the automatic material handling equipment in the next process. During the process of switching the four sets of feeding plates 803 from a layered stacked distribution to a stepped distribution, the rotating first worm gear 806 drives the support shaft 8022 and the fixed arm 8021 to rotate together. The fixed arm 8021 drives the cross-scissor telescopic frame 8023 to rotate through the cooperation of the guide member 8025 and the connecting shaft 8026. At the same time, the cross-scissor telescopic frame 8023 drives the feeding plates 803 to move, and the cross-scissor telescopic frame 8023 drives the receiving shaft 8028 to slide along the arc groove 31. Through the limiting of the arc groove 31, the length of the cross-scissor telescopic frame 8023 remains unchanged during the rotation, thereby changing the four sets of feeding plates 803 from a layered stacked distribution to a stepped distribution. When the distribution of the four sets of feeding plates 803 is changed from a stepped distribution to a layered stacked distribution, the second double worm gear 11 is rotated by a wrench. The second double worm gear 11 drives the two sets of second worm wheels 12 to rotate. The second worm wheels 12 drive the corresponding turntable 14 to rotate. The rotating turntable 14 drives the pin shaft 141 to press against the inner wall of the straight groove 21, causing the lifting plate 8092 and the limiting plate 8093 to move downward. The limiting plate 8093 drives the receiving shaft 8028 to move downward through the arc groove 31. The receiving shaft 8028 causes the cross-scissor telescopic frame 8023 to retract through the node, thereby reducing the spacing between the four sets of feeding plates 803.
