Technical Field
[0001] This utility model relates to an automatic lifting stress-relief sintering furnace, and in particular to an automatic lifting stress-relief sintering furnace applied in the field of sintering furnace technology. Background Technology
[0002] In the material processing, sintering is a key process that enables powder compacts to obtain the desired physical and mechanical properties and microstructure through high-temperature treatment.
[0003] Chinese patent CN220472292U discloses a sintering furnace. This utility model, through a support plate and multiple trays set on one side of the furnace door, as well as multiple casters at the bottom of the furnace door, allows for convenient removal of the electronic paste from the sintering furnace after sintering by moving the furnace door. This avoids close contact with the sintering furnace when handling the electronic paste, effectively preventing burns from the residual heat in the sterilizer. It not only improves the efficiency of electronic paste sintering operations but also reduces safety hazards, making it safer to use.
[0004] Traditional sintering furnaces are mostly fixed structures, and the loading and unloading of materials usually requires manual handling. For large or heavy materials, manual handling not only consumes a lot of manpower, but also easily leads to material damage during the handling process. Utility Model Content
[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that for large or heavy materials, manual handling not only consumes a lot of manpower, but also easily leads to damage to the materials during the handling process.
[0006] To address the aforementioned problems, this utility model provides an automatic lifting stress-relief sintering furnace, comprising a sintering furnace body. Conveying shafts are installed at both the inlet and outlet of the sintering furnace body. A bracket is fixedly connected to the side end of the conveying shaft at the inlet. A reel is rotatably connected to the inner wall of the bracket at the top. Two sets of limiting plates are symmetrically fitted onto the surface of the reel. A pull rope is wound around the surface of the reel between each set of limiting plates. A hook is fixedly connected to the end of the pull rope away from the reel. A transport vehicle is placed inside the bracket, and a placement frame is placed on the transport vehicle. Clamping rings are symmetrically fixedly connected to the top of the placement frame. A sliding plate is installed on the side of the bracket away from the conveying shaft. An electric push rod is detachably connected to the middle of the sliding plate. A push plate is detachably connected to the movable end of the electric push rod. A support plate is fixedly connected to the side end of the bracket.
[0007] In the aforementioned sintering furnace, the items to be processed are lifted by a rope and then pushed onto a conveyor shaft by an electric actuator to be transported into the sintering furnace body for processing, achieving automatic lifting and handling and reducing labor costs.
[0008] As a further improvement of this application, a servo motor is fixedly connected to the pallet, and the output end of the servo motor is connected to the reel.
[0009] As a further improvement of this application, the support has symmetrical grooves on the cross section at the end away from the conveying shaft, an electric slide rail is fixedly connected in the groove, and the slide plate is connected to the electric slide rail through a slider.
[0010] As a further improvement of this application, a mounting sleeve is embedded in the skateboard, and the electric actuator engages with the mounting sleeve.
[0011] As another improvement of this application, clamps are symmetrically fitted on the surface of the connection between the mounting sleeve and the electric actuator, and the two clamps are fixed by bolts.
[0012] As a further improvement to this application, the movable end of the electric actuator is provided with a slot, and a locking block is fixedly connected to one end of the push plate near the electric actuator, and the locking block engages with the slot.
[0013] As a further improvement to this application, a controller for controlling electric push rods, servo motors, conveyor shafts, and electric slide rails is fixedly connected to the sintering furnace body.
[0014] In summary, the placement frame filled with the items to be processed is placed on the transport vehicle and then transported to the support located directly below the reel. At this point, the two hooks are engaged with the retaining rings, and the servo motor is activated by the controller to drive the reel to rotate, thereby winding up the pull rope. During winding, the placement frame is lifted up. When the bottom of the placement frame rises to be level with the top of the conveyor shaft, the electric push rod can be activated by the controller to push the push plate. The push plate abuts against the side of the placement frame, pushing the suspended placement frame above the conveyor shaft. After it is placed stably, the hooks can be removed from the retaining rings. At this time, the placement frame is transported to the sintering furnace body through the conveyor shaft for processing.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0024] First implementation method:
[0025] Figures 1-4 An automatic lifting stress-relief sintering furnace is shown, including a sintering furnace body 1. A conveyor shaft 2 is installed at both the inlet and outlet of the sintering furnace body 1. A bracket 3 is fixedly connected to the side end of the conveyor shaft 2 at the inlet. A roller 5 is rotatably connected to the inner wall of the bracket 3 at the top. Two sets of limiting plates 6 are symmetrically sleeved on the surface of the roller 5. A pull rope 7 is wound around the surface of the roller 5 between each set of limiting plates 6. A hook 8 is fixedly connected to the end of the pull rope 7 away from the roller 5. A transport vehicle 9 is placed inside the bracket 3. A placement frame 10 is placed on the transport vehicle 9. A retaining ring 11 is symmetrically fixedly connected to the top of the placement frame 10. A sliding plate 13 is installed on the side of the bracket 3 away from the conveyor shaft 2. An electric push rod 14 is detachably connected to the middle of the sliding plate 13. A push plate 17 is detachably connected to the movable end of the electric push rod 14. A support plate is fixedly connected to the side end of the bracket 3. A servo motor 4 is fixedly connected to the support plate, and the output end of the servo motor 4 is connected to the roller 5.
[0026] Working principle: The placement frame 10 filled with the items to be processed is placed on the transport vehicle 9 and then transported to the bracket 3 located directly below the reel 5. At this time, the two hooks 8 are respectively engaged with the retaining rings 11. Then, the servo motor 4 is turned on by the controller to drive the reel 5 to rotate, thereby winding the pull rope 7. During the winding, the placement frame 10 is lifted up. When the bottom of the placement frame 10 rises to be level with the top of the conveyor shaft 2, the electric push rod 14 can be turned on by the controller to push the push plate 17. The push plate 17 abuts against the side of the placement frame 10, pushing the suspended placement frame 10 above the conveyor shaft 2. After it is placed stably, the hooks 8 can be removed from the retaining rings 11. At this time, the placement frame 10 is transported to the sintering furnace body 1 through the conveyor shaft 2 for processing.
[0027] After the items to be processed are lifted by the pull rope 7, they are pushed onto the conveyor shaft 2 by the electric push rod 14 and transported into the sintering furnace body 1 for processing, achieving automatic lifting and handling and reducing labor costs.
[0028] Second implementation method:
[0029] Figure 2 and Figures 5-6 The support 3 has a symmetrically arranged groove 12 at the end away from the conveyor shaft 2. An electric slide rail is fixedly connected in the groove 12. The slide plate 13 is connected to the electric slide rail through the slider 19. The slide plate 13 has an embedded mounting sleeve 16. The electric push rod 14 is engaged with the mounting sleeve 16. The surface of the connection between the mounting sleeve 16 and the electric push rod 14 is symmetrically fitted with clamps 15. The two clamps 15 are fixed by bolts. The movable end of the electric push rod 14 has a slot 18. The push plate 17 is fixedly connected to a locking block 20 at the end near the electric push rod 14. The locking block 20 is engaged with the slot 18. The sintering furnace body 1 is fixedly connected to a controller that controls the electric push rod 14, the servo motor 4, the conveyor shaft 2, and the electric slide rail.
[0030] Working principle: After the placement frame 10 is lifted by the pull rope 7, the position of the push plate 17 can be adjusted by the electric slide rail driven by the controller to move the slide plate 13 up and down according to the different sizes of the placement frame 10, so that the push plate 17 is precisely in contact with the bottom section of the placement frame 10. When the electric push rod 14 malfunctions during use, the bolts can be loosened to remove the two clamps 15 from the surface of the electric push rod 14 and the mounting sleeve 16, so that the electric push rod 14 can be pulled out from the mounting sleeve 16 for maintenance. The push plate 17 and the movable end of the electric push rod 14 are connected by the slot 18 and the block 20, which can be easily disassembled and replaced.
[0031] The electric actuator 14 and the mounting sleeve 16 are detachably connected by the clamp 15, which facilitates replacement and maintenance during long-term use, and also makes it easy to disassemble and replace the push plate 17.
[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
