Description

Technical Field

[0001] This utility model relates to a metal heat treatment furnace, specifically a heat treatment furnace for aluminum-magnesium alloy processing, belonging to the technical field of metal material heat treatment equipment. Background Technology

[0002] Aluminum-magnesium alloys, with their low density, high strength, and good dimensional stability, are widely used in many fields such as aerospace, automotive manufacturing, and electronic equipment. In the processing of aluminum-magnesium alloys, heat treatment is a key step in improving material properties. During heat treatment, the alloy parts are placed inside a material frame, and then the frame containing the alloy parts is placed in a heat treatment furnace for heating.

[0003] However, in traditional heat treatment furnaces, after the alloy parts have undergone heat treatment, the removal of the material frame requires operators to first use forklifts or other handling equipment to move the frame out of the furnace before transferring it. Because manual operation is difficult to guarantee precision, the frame is highly susceptible to collisions with the furnace wall during handling. This not only increases equipment maintenance and workpiece damage costs but also poses a risk of burns and injuries from tipping over, seriously threatening the safety of operators and resulting in poor operational safety. Utility Model Content

[0004] The purpose of this utility model is to provide a heat treatment furnace for aluminum-magnesium alloy processing in order to solve the above problems. After the heat treatment is completed, the material frame can be automatically moved from the inside of the heat treatment furnace to the outside of the heat treatment furnace along a specific trajectory, thereby avoiding collision between the material frame and the inner wall of the heat treatment furnace, effectively improving the safety of operation, while improving the handling efficiency and speeding up the production pace.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a heat treatment furnace for aluminum-magnesium alloy processing, comprising a heating furnace body, a supporting structure on the heating furnace body, the supporting structure including a first cylinder and a connecting frame, a first cylinder installed on each side of the heating furnace body, the extended end of the first cylinder being fixedly connected to the connecting frame, multiple rotating rollers rotatably connected inside the heating furnace body, the top sides of the multiple rotating rollers abutting against the bottom side of the same carrying plate, two moving wheels rotatably connected to the carrying plate, a connecting shaft fixedly connected to each side of the carrying plate, the connecting shaft extending into the interior of the adjacent connecting frame and slidably connected to the connecting frame, a sealing door slidably connected to the heating furnace body, and a buffer structure provided on the heating furnace body.

[0006] Preferably, the bottom side of the carrier plate is provided with a groove, and the top side of the roller is located inside the groove.

[0007] Preferably, the top side of the loading plate is provided with a slot, and the width of the slot cross-section is equal to the width of the sealing door cross-section.

[0008] Preferably, the buffer structure includes a connecting sleeve and a stop sleeve. The connecting sleeve is fixedly connected inside the heating furnace body, and the stop sleeve is slidably connected inside the connecting sleeve. One end of the stop sleeve abuts against one end of the carrying plate, and multiple springs abut against the connecting sleeve.

[0009] Preferably, two second cylinders are installed on the heating furnace body, and the extended ends of the second cylinders are fixedly connected to the sealing door, and the sealing door is provided with a counterweight structure.

[0010] Preferably, the counterweight structure includes connecting ropes and connecting frames. Two connecting ropes are fixedly connected to the top of the sealing door, and one end of each of the two connecting ropes is fixedly connected to the same connecting frame. A counterweight block is fixedly connected to the connecting frame. Two connecting seats are fixedly connected to the heating furnace body, and pulleys are rotatably connected to the connecting seats. The connecting ropes are wound around adjacent pulleys.

[0011] Preferably, two guide columns are fixedly connected to the heating furnace body, and the two guide columns are slidably connected to the same connecting frame.

[0012] Preferably, the two guide posts are symmetrically distributed about the middle of the connecting frame, and the two connecting ropes are symmetrically distributed about the middle of the sealing door.

[0013] The beneficial effects of this utility model are as follows: During use, the material frame can be placed on the carrier plate. After the aluminum-magnesium alloy parts have been heat-treated, the sealing door can be opened first. Then, by simultaneously activating two first cylinders, the extension of the first cylinders will drive the connecting frame to move. The movement of the connecting frame will abut against the connecting shaft. The two connecting shafts will be simultaneously subjected to force, causing the carrier plate to move. This allows the carrier plate to move from the inside of the heating furnace to the outside of the heating furnace. During the movement of the carrier plate, the two moving wheels will roll on the ground, and the rotating rollers in contact with the carrier plate will rotate, thus making the movement of the carrier plate smoother. Since the carrier plate moves along a specific motion trajectory, the material frame on the carrier plate will also move along a specific motion trajectory, thereby avoiding collisions between the material frame and the inner wall of the heating furnace during the movement. This effectively improves the safety of operation, while also increasing the handling efficiency and accelerating the production pace. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, a heat treatment furnace for aluminum-magnesium alloy processing includes a heating furnace body 1. The heating furnace body 1 is provided with a supporting structure 2. The supporting structure 2 includes a first cylinder 201 and a connecting frame 202. A first cylinder 201 is installed on each side of the heating furnace body 1. The extended end of the first cylinder 201 is fixedly connected to the connecting frame 202. Multiple rotating rollers 208 are rotatably connected inside the heating furnace body 1. The top side of the multiple rotating rollers 208 abuts against the bottom side of the same carrying plate 204. Two moving wheels 205 are rotatably connected to the carrying plate 204. A connecting shaft 203 is fixedly connected to each side of the carrying plate 204. The connecting shaft 203 extends into the interior of the adjacent connecting frame 202 and is slidably connected to the connecting frame 202. A sealing door 5 is slidably connected to the heating furnace body 1. A buffer structure 3 is provided on the heating furnace body 1.

[0022] As a technical optimization of this utility model, the bottom side of the carrying plate 204 is provided with a groove 207, and the top side of the rotating roller 208 is located inside the groove 207, so that the carrying plate 204 can be limited.

[0023] As a technical optimization of this utility model, the top side of the carrying plate 204 is provided with a slot 206. The width of the cross section of the slot 206 is equal to the width of the cross section of the sealing door 5. The bottom end of the sealing door 5 can be inserted into the slot 206 to limit the movement of the carrying plate 204.

[0024] As a technical optimization of this utility model, the buffer structure 3 includes a connecting sleeve 301 and a stop sleeve 302. The connecting sleeve 301 is fixedly connected inside the heating furnace body 1. The connecting sleeve 301 can guide the movement of the stop sleeve 302. The stop sleeve 302 is slidably connected inside the connecting sleeve 301. One end of the stop sleeve 302 abuts against one end of the carrying plate 204. Multiple springs 303 abut against the stop sleeve 302 and the connecting sleeve 301. Therefore, the multiple springs 303 can buffer the carrying plate 204, avoiding the sudden impact of the carrying plate 204 against the inner wall of the heating furnace body 1, thereby improving the safety of use. When it is necessary to move the carrying plate 204 in the opposite direction, the multiple springs 303 can apply a pushing force to the carrying plate 204, thereby facilitating the reverse movement of the carrying plate 204.

[0025] As a technical optimization of this utility model, two second cylinders 4 are installed on the heating furnace body 1. The movement of the sealing door 5 can be controlled by the two second cylinders 4. The extended end of the second cylinder 4 is fixedly connected to the sealing door 5. The sealing door 5 is provided with a counterweight structure 6.

[0026] As a technical optimization of this utility model, the counterweight structure 6 includes a connecting rope 601 and a connecting frame 602. Two connecting ropes 601 are fixedly connected to the top of the sealing door 5. The connecting ropes 601 can connect the connecting frame 602 and the sealing door 5. One end of the two connecting ropes 601 is fixedly connected to the same connecting frame 602. The counterweight block 604 can be installed through the connecting frame 602. The counterweight block 604 is fixedly connected to the connecting frame 602. The counterweight block 604 can offset part of the weight of the sealing door 5, so that it is easier to control the movement of the sealing door 5. Two connecting seats 605 are fixedly connected to the heating furnace body 1. The connecting seats 605 can support the pulley 606. The pulley 606 is rotatably connected to the connecting seat 605. The connecting rope 601 is wound around the adjacent pulley 606. The pulley 606 can change the direction of the connecting rope 601.

[0027] As a technical optimization of this utility model, two guide columns 603 are fixedly connected to the heating furnace body 1. The guide columns 603 can guide the movement of the connecting frame 602, so as to avoid the connecting frame 602 swinging and colliding with the heating furnace body 1 during the movement. The two guide columns 603 are slidably connected to the same connecting frame 602.

[0028] As a technical optimization of this utility model, the two guide columns 603 are symmetrically distributed about the middle of the connecting frame 602, thus providing better guidance for the movement of the connecting frame 602. The two connecting ropes 601 are symmetrically distributed about the middle of the sealing door 5, thus providing better pulling for the sealing door 5.

[0029] In use, this invention allows the material frame to be placed on the carrier plate 204. Simultaneous activation of two first cylinders 201 causes them to retract, moving the carrier plate 204 towards the interior of the heating furnace body 1. During this movement, the carrier plate 204 first contacts the abutment sleeve 302, which then slides inside the connecting sleeve 301. At this time, multiple springs 303 retract simultaneously, thus buffering the carrier plate 204 and preventing a sudden impact from the inner wall of the heating furnace body 1, thereby improving safety. Furthermore, when reversing the movement of the carrier plate is required... When the material frame moves into the interior of the heating furnace body 1, it can apply a pushing force to the material frame 204 under the action of multiple springs 303, thereby facilitating the reverse movement of the material frame 204. When the material frame moves into the interior of the heating furnace body 1, two second cylinders 4 can be activated simultaneously. The retraction of the second cylinders 4 will cause the sealing door 5 to move towards the material frame 204. When the bottom end of the sealing door 5 is inside the slot 206 and abuts against the material frame 204, the second cylinders 4 stop retracting. At this time, the front end of the heating furnace body 1 can be sealed by the sealing door 5. At the same time, the bottom end of the sealing door can also be inserted into the slot 206 to limit the movement of the material frame 204. Then, the aluminum can be processed. Magnesium alloy parts undergo heat treatment. After the magnesium alloy parts are heat-treated, the sealing door 5 can be opened first. During the opening process, the sealing door 5 moves upward, and the counterweight 604 moves downward. The downward movement of the counterweight 604 drives the connecting frame 602 to move. The connecting frame 602 pulls the sealing door 5 upward through two connecting ropes 601, thereby offsetting part of the weight of the sealing door 5 and facilitating its opening. When the sealing door 5 is opened, two first cylinders 201 are activated simultaneously. The extension of the first cylinders 201 drives the connecting frame 202 to move. The movement of the connecting frame 202 abuts against the connecting shaft 203, and both connecting shafts 203 are simultaneously subjected to force. This will cause the carrier plate 204 to move, thereby moving the carrier plate 204 from the inside of the heating furnace body 1 to the outside of the heating furnace body 1. During the movement of the carrier plate 204, the two moving wheels 205 will roll on the ground, and at the same time, the rotating roller 208 in contact with the carrier plate 204 will rotate, thereby making the movement of the carrier plate 204 smoother. Since the carrier plate 204 moves along a specific movement trajectory, the material frame on the carrier plate 204 will also move along a specific movement trajectory, thereby avoiding collisions between the material frame and the inner wall of the heating furnace body 1 during the movement, effectively improving the safety of operation, while improving the handling efficiency and speeding up the production rhythm.
