Description

Technical Field

[0001] This invention belongs to the field of annealing furnace technology, specifically referring to a heat treatment heating furnace with conveying function. Background Technology

[0002] Annealing is a process in which metal is heated to a certain temperature, held at that temperature, and then slowly cooled. Its purpose is to soften the material, eliminate internal stress, and refine the grain size. It typically requires heating the material in a furnace to 800-900℃ and holding it at that temperature for a period of time. The loading and unloading process in traditional annealing furnaces is mostly done manually, which is time-consuming and labor-intensive. This is mainly because the automation of annealing furnace loading and unloading still faces the following challenges: A: The temperature inside the furnace is high, and the high temperature will cause the stator of the motor to demagnetize and fail. Although some furnaces can be equipped with heat insulation jackets, the temperature inside the jacket is generally only below 100 degrees Celsius at the far end. The electric drive device cannot be installed in the part of the jacket that is close to the heat source, which makes it difficult to achieve automatic control of the structure in the high temperature zone. B: The internal space of the mezzanine is cramped and the heat dissipation pressure is high. Therefore, if a large number of electric drive mechanisms are installed, not only will the interference problem be difficult to solve, but the temperature of the motor working area may also be further increased. C: Because metal itself has strong thermal conductivity, even if the motor is located far away, if there is a metal connecting rod that is always connected, the heat on the swing heating frame can still be slowly conducted to the motor. D: Rollers used for conveying materials (free rotation). If the temperature difference in the working area is too large, they will jam and fail due to material deformation caused by thermal expansion and contraction. Summary of the Invention

[0003] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a heat treatment furnace with a conveying function. To solve the problem of temperature difference deformation of the rollers, this invention starts from the source by setting up a liftable track support frame and sleeve roller assembly. By lowering the roller assembly, the distance between the sleeve roller assembly and the heating module during heat treatment is increased, thereby reducing the temperature rise of the sleeve roller assembly by reducing heat radiation. At the same time, through the electric pusher cylinder located in the low-temperature zone on the outermost side of the interlayer, combined with the specific design of vertical and curved slides, the position and angle of the track support frame are controlled. Meanwhile, this solution proposes a flexible connection component with no driving source and a higher upper temperature limit. The movement of the track support frame enables the active connection and separation between the track support component and the heating component. On the one hand, the track support frame can be used to adjust the pitch angle of the swing heating frame, realizing automatic feeding based on gravity. On the other hand, the drive connection scheme with short-term connection can cut off the heat conduction path in the heat treatment process, thereby avoiding the problem of excessive motor temperature rise when connected for a long time.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a heat treatment heating furnace with conveying function, including an outer shell, an elastic connecting assembly, a track support assembly, an inner shell, a heating assembly, a sleeve roller assembly, a push rod and a drive assembly. The heating assembly is located inside the inner shell. The elastic connecting assembly includes a first connecting cylinder, a spring, a double-beveled locking tongue and a second connecting cylinder. The first connecting cylinder is fixed to the track support assembly, and the second connecting cylinder is fixed to the heating assembly. The first connecting cylinder and the second connecting cylinder are connected by a spring and a double-beveled locking tongue. When the first connecting cylinder and the second connecting cylinder are connected, the track support assembly is located on the extension line of the heating assembly. The sleeve roller assembly array is disposed on the track support assembly, the drive assembly is disposed between the outer shell and the inner shell, and the push rod is disposed on the external drive source.

[0005] Furthermore, the track support assembly includes a track support frame and end shafts. The end shafts are symmetrically arranged on the outer side of the end of the track support frame. The heating assembly includes a swing heating frame with swing shafts at both ends. The inner housing is provided with a vertical slide groove, a curved slide groove, and a hinge hole. The two sets of end shafts are respectively engaged and slidably arranged in the vertical slide groove and the curved slide groove. The swing shaft is rotatably arranged in the hinge hole.

[0006] Preferably, the first connecting cylinder is fixedly connected to the end shaft located in the vertical sliding groove, the second connecting cylinder is fixedly connected to the swing shaft, the first connecting cylinder is provided with a locking tongue sliding groove, the double-sloping locking tongue is engaged and slidably disposed in the locking tongue sliding groove, the spring is disposed between the locking tongue sliding groove and the double-sloping locking tongue, and the second connecting cylinder is provided with a double-sloping locking groove that matches the double-sloping locking tongue.

[0007] Preferably, the curved slide is composed of an interconnected arc-shaped part, a vertical part and a horizontal part from top to bottom. The position and angle of the track support frame can be adjusted by sliding the end shaft in the curved slide.

[0008] Furthermore, the track support assembly also includes a vertical heat-insulating sleeve and a curved heat-insulating sleeve, the vertical heat-insulating sleeve being fixed to the outside of the vertical slide groove, and the end shaft being able to pass through the vertical heat-insulating sleeve and slide. Preferably, the curved heat-insulating sleeve is fixed to the outside of the curved slide groove, and the end shaft can pass through the curved heat-insulating sleeve and slide.

[0009] Furthermore, the heating assembly also includes a stop platform, which is fixed to the inner side of the inner shell and located at the bottom of the swing heating frame. The swing shaft is located on the side of the swing heating frame near the track support assembly. When the workpiece is on the swing heating frame, the swing heating frame will fall on the stop platform and remain horizontal.

[0010] Preferably, the heating assembly further includes a heating module, which is fixed to the inner side of the inner shell and located above the swing heating frame. The edge of the non-feed end of the swing heating frame is provided with a fence, and the swing heating frame is also provided with a grid.

[0011] Furthermore, the sleeve roller assembly includes an end support shaft and a free sleeve, the end support shaft array being fixedly connected to the track support frame, and the free sleeve being sleeved on the end support shaft.

[0012] Furthermore, the drive assembly includes a fixed shaft and an electric pusher cylinder. The fixed shaft is fixed to the outside of the inner housing, one end of the electric pusher cylinder is hinged to the fixed shaft, and the other end of the electric pusher cylinder is hinged to a set of end shafts in a curved slide groove.

[0013] The spring is made of a nickel-based alloy.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) By adjusting the position and angle of the track support assembly and the sleeve roller assembly, this solution can, on the one hand, make the sleeve roller assembly move away from the high temperature area where the heating assembly is located after the feeding is completed; on the other hand, it can also control the angle of the heating assembly by connecting and disconnecting the elastic connection assembly, so as to remove the high temperature workpiece without the need for the fixture to enter.

[0015] (2) The track support assembly and the heating assembly are automatically connected and non-rigidly connected through the elastic connection assembly, thereby achieving the purpose of controlling the high temperature components in the low temperature zone and solving the problem that the drive component cannot be directly connected to the high temperature components.

[0016] (3) Through the design of vertical and curved slides, the angle and position of the track support component in the medium temperature zone can be adjusted by the drive component located in the low temperature zone at the far end. At the same time, the pitch swing of the swing heating frame in the high temperature zone can be further controlled by the automatically combined elastic connection component, so as to realize the technical function of automatic feeding.

[0017] (4) Vertical and curved heat insulation sleeves are used to block the airflow between the inside and outside of the inner shell. Although they cannot completely insulate the heat, they can significantly increase the temperature difference between the inside and outside of the inner shell.

[0018] (5) The interior of the outer shell is divided into multiple temperature spaces with different gradients based on the heat insulation material and distance. The installation positions of each mechanism are arranged according to the heat resistance of the material, so that the active control of the action of each mechanism can be realized under the premise of meeting the temperature conditions.

[0019] (6) When the workpiece is pushed onto the swing heating frame by the push rod, it can resist the fence, thereby temporarily locking the state of the swing heating frame by the push force of the push rod. At this time, the track support assembly will not cause the swing heating frame to deflect when it moves, thereby preventing the unheated workpiece from falling.

[0020] (7) The free sleeve is fitted on the end support shaft. On the one hand, it can transport the workpiece by its own rotation. On the other hand, since the free sleeve is relatively free, it can avoid jamming when the free sleeve expands and contracts.

[0021] (8) The swing shaft and the end shaft are only temporarily connected by the elastic connection component during the feeding stage. By disconnecting the heat conduction path, the temperature rise of the drive mechanism is reduced, and the problem of overheating failure of the electric drive component is avoided.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] like Figures 1-10 As shown, the present invention proposes a heat treatment heating furnace with conveying function, including an outer shell 1, an elastic connection assembly 2, a track support assembly 3, an inner shell 4, a heating assembly 5, a sleeve roller assembly 6, a push rod 7, and a drive assembly 8; This solution adjusts the position and angle of the track support assembly 3 and the sleeve roller assembly 6. On the one hand, it can move the sleeve roller assembly 6 away from the high-temperature area where the heating assembly 5 is located after the feeding is completed. On the other hand, it can control the angle of the heating assembly 5 by connecting and disconnecting the elastic connection assembly 2, thereby enabling the removal of the high-temperature workpiece without the need for a fixture to enter.

[0028] The heating component 5 is located inside the inner shell 4. The elastic connection component 2 includes a first connecting cylinder 21, a spring 22, a double-beveled locking tongue 23, and a second connecting cylinder 24. The first connecting cylinder 21 is fixed to the track support component 3, and the second connecting cylinder 24 is fixed to the heating component 5. The first connecting cylinder 21 and the second connecting cylinder 24 are connected by the spring 22 and the double-beveled locking tongue 23. When the first connecting cylinder 21 and the second connecting cylinder 24 are connected, the track support component 3 is located on the extension line of the heating component 5. The track support assembly 3 and the heating assembly 5 are automatically connected and non-rigidly linked through the elastic connection assembly 2, thereby achieving the purpose of controlling high-temperature components in the low-temperature zone and solving the problem that the drive component cannot be directly connected to the high-temperature component.

[0029] The sleeve roller assembly 6 is arrayed on the track support assembly 3, the drive assembly 8 is located between the outer shell 1 and the inner shell 4, and the push rod 7 is located on the external drive source.

[0030] The track support assembly 3 includes a track support frame 31 and an end shaft 32. The end shafts 32 are symmetrically arranged on the outer side of the end of the track support frame 31. The heating assembly 5 includes a swing heating frame 51. The swing heating frame 51 has swing shafts 513 at both ends. The inner shell 4 is provided with a vertical slide groove 41, a curved slide groove 42 and a hinge hole 46. The two sets of end shafts 32 are respectively engaged and slidably arranged in the vertical slide groove 41 and the curved slide groove 42. The swing shafts 513 are rotatably arranged in the hinge hole 46.

[0031] By designing the vertical slide 41 and the curved slide 42, the angle and position of the track support component 3 in the medium temperature zone can be adjusted by the drive component 8 located in the low temperature zone at the far end. At the same time, the pitch and sway of the swing heating frame 51 in the high temperature zone can be further controlled by the automatically combined elastic connection component 2, so as to realize the technical function of automatic feeding.

[0032] The first connecting cylinder 21 is fixedly connected to the end shaft 32 located in the vertical slide groove 41, and the second connecting cylinder 24 is fixedly connected to the swing shaft 513. The first connecting cylinder 21 is provided with a locking tongue slide groove 211, and the double inclined locking tongue 23 is engaged and slidably disposed in the locking tongue slide groove 211. The spring 22 is disposed between the locking tongue slide groove 211 and the double inclined locking tongue 23. The second connecting cylinder 24 is provided with a double inclined groove 241 that matches the double inclined locking tongue 23.

[0033] The curved slide 42 is composed of an interconnected arc-shaped part 43, a vertical part 44 and a horizontal part 45 from top to bottom. The position and angle of the track support frame 31 can be adjusted by sliding the end shaft 32 in the curved slide 42.

[0034] The track support assembly 3 also includes a vertical heat insulation sleeve 33 and a curved heat insulation sleeve 34. The vertical heat insulation sleeve 33 is fixed to the outside of the vertical slide groove 41, and the end shaft 32 can pass through the vertical heat insulation sleeve 33 and slide. The curved heat insulation sleeve 34 is fixed to the outside of the curved slide groove 42, and the end shaft 32 can pass through the curved heat insulation sleeve 34 and slide.

[0035] The vertical heat insulation sleeve 33 and the curved heat insulation sleeve 34 are used to block the airflow between the inside and outside of the inner shell 4. Although they cannot completely insulate the heat, they can significantly increase the temperature difference between the inside and outside of the inner shell 4.

[0036] The interior of the outer shell 1 is divided into multiple temperature zones with different gradients based on the heat insulation material and distance. The installation positions of each mechanism are arranged according to the heat resistance of the material, which enables active control of the actions of each mechanism while meeting the temperature conditions.

[0037] The heating assembly 5 also includes a stop 52, which is fixed to the inside of the inner housing 4 and located at the bottom of the swing heating frame 51. The swing shaft 513 is located on the side of the swing heating frame 51 near the track support assembly 3. When the workpiece is on the swing heating frame 51, the swing heating frame 51 will fall on the stop 52 and remain horizontal.

[0038] The heating assembly 5 also includes a heating module 53, which is fixed to the inner side of the inner housing 4 and located above the swing heating frame 51. A fence 511 is provided at the edge of the non-feed end of the swing heating frame 51, and a grid 512 is also provided on the swing heating frame 51.

[0039] When the workpiece is pushed onto the swing heating frame 51 by the push rod 7, it can abut against the fence 511, thereby temporarily locking the state of the swing heating frame 51 by the pushing force of the push rod 7. At this time, the track support assembly 3 will not cause the swing heating frame 51 to deflect when it moves, thereby preventing the unheated workpiece from falling.

[0040] The sleeve roller assembly 6 includes an end support shaft 61 and a free sleeve 62. The end support shaft 61 is fixedly connected to the track support frame 31 in an array, and the free sleeve 62 is sleeved on the end support shaft 61.

[0041] The free sleeve 62 is sleeved on the end support shaft 61. On the one hand, it can realize the conveying of the workpiece through its own rotation. On the other hand, because the free sleeve 62 is relatively free, it can also avoid jamming when the free sleeve 62 expands and contracts with heat.

[0042] The drive assembly 8 includes a fixed shaft 81 and an electric push cylinder 82. The fixed shaft 81 is fixed to the outside of the inner housing 4. One end of the electric push cylinder 82 is hinged to the fixed shaft 81, and the other end of the electric push cylinder 82 is hinged to a set of end shafts 32 in the curved slide 42.

[0043] Spring 22 is made of nickel-based alloy.

[0044] like Figure 5As shown, a, b, c, and d are the positions of the track support frame 31 at different stages. When the track support frame 31 is at the bottom position d, the right side of the track support frame 31 is slightly higher than the left side. At this time, the electric push cylinder 82 retracts. While the left end of the track support frame 31 moves to the right along the horizontal part 45, the right end of the track support frame 31 also moves up along the vertical slide 41 until the track support frame 31 reaches c. As the electric cylinder 82 continues to retract, the track support frame 31 moves upward to point b. The electric cylinder 82 continues to retract, at which point the end shaft 32 has reached the top of the vertical slide 41. Therefore, the end shaft 32 in the curved slide 42 will swing upward along the arc 43 until it reaches the horizontal position a.

[0045] like Figure 4 As shown, the temperature of various parts inside the outer casing 1 is mainly affected by two factors: the distance from the heat source and the effect of the insulation material. The device is divided into three different temperature zones along the dotted line. Zone A is the high-temperature zone (approximately 400~900 degrees Celsius) where the heating component 5 is located, Zone B is the medium-temperature zone (approximately 100~400 degrees Celsius) where the elastic connection component 2 and the sleeve roller component 6 are located, and Zone C is the low-temperature zone (below 100 degrees Celsius) where the drive component 8 is located. The swing heating frame 51 is made of ceramic composite material with a maximum operating temperature of 1200 degrees Celsius. The elastic connection component 2 is made of nickel-based alloy with a maximum operating temperature of 550 degrees Celsius. The electric push cylinder 82 has a maximum operating temperature of 140 degrees Celsius. The above materials or modules can work stably within the corresponding temperature range.

[0046] In actual use, the track support frame 31 is initially located at the top horizontal position. First, the unheated workpiece is placed on the free sleeve 62 by the external clamping device. Then, the workpiece is pushed along the free sleeve 62 to the swing heating frame 51 by the external mechanism driving the push rod 7. At this time, the swing heating frame 51 has not yet fully risen to the highest temperature. When the workpiece presses against the rear railing 511, the swing heating frame 51 will also apply pressure to the stop table 52. At this time, the push rod 7 is kept in its current state, and the swing heating frame 51 is temporarily locked at that angle.

[0047] Then, the electric push cylinder 82 is extended, and the end shaft 32 located in the curved slide 42 will first slide down along the arc 43. When the track support frame 31 is tilted and the swing heating frame 51 is still horizontal, the double inclined locking tongue 23 will disengage from the double inclined slot 241, and the connection between the track support assembly 3 and the heating assembly 5 will be released. As the electric cylinder 82 continues to extend, the track support frame 31 moves horizontally and descends to the bottom. The end shaft 32 then enters the horizontal part 45 from the vertical part 44, at which point the track support frame 31 tilts slightly.

[0048] Then the heating module 53 is activated to heat the workpiece on the swing heating frame 51. Since the swing shaft 513 is located on the side of the swing heating frame 51 close to the sleeve roller assembly 6, the weight of the workpiece will cause the swing heating frame 51 to press against the stop table 52 and remain horizontal. At this time, the end support shaft 61 and the free sleeve 62 have moved away from the heating module 53 by the descent of the track support frame 31, and moved from the high temperature zone to the medium temperature zone, reducing the temperature change range of the free sleeve 62 throughout the entire working cycle; thereby avoiding problems such as excessive deformation, material cracking, jamming and inability to rotate caused by excessive temperature difference in the free sleeve 62.

[0049] After the heat treatment is completed, the fixture is difficult to reach due to the high temperature of the swing heating frame 51 and the workpiece; and there may not be a suitable clamping position on the workpiece. At this time, the electric push cylinder 82 is controlled to retract. Since the end shaft 32 in the vertical slide 41 is slightly higher than the end shaft 32 in the curved slide 42, when the electric push cylinder 82 pulls the end shaft 32 to move laterally in the horizontal part 45, the end shaft 32 in the vertical slide 41 will slide upward at the same time, increasing the tilt of the track support frame 31. When the end shaft 32 is transferred from the horizontal part 45 to the vertical part 44, the track support frame 31 will move upward with the sleeve roller assembly 6. When the end shaft 32 slides to the top of the vertical slide 41, the end shaft 32 in the curved slide 42 will also just be transferred from the vertical part 44 to the arc-shaped part 43. As the end shaft 32 slides upward along the arc-shaped part 43, the track support frame 31 gradually changes from inclined to horizontal. After the double-sloped locking tongue 23 abuts against the connecting cylinder 24, it retracts against the elastic force of the spring 22. When the track support frame 31 reaches the horizontal state, the double-sloped locking tongue 23 just fits into the double-sloped slot 241. The track support assembly 3 and the heating assembly 5 are connected through the elastic connecting assembly 2.

[0050] At this point, the electric actuator 82 extends in the reverse direction until the track support frame 31 reaches slightly below... Figure 5 When the workpiece is at position b, the swing shaft 513 is just located on the extension line of the track support frame 31. At this time, the swing heating frame 51 and the free sleeve 62 are on the same inclined plane (this position is the critical position for the separation of the first connecting sleeve 21 and the second connecting sleeve 24. If the track support frame 31 continues to descend, the first connecting sleeve 21 will separate from the second connecting sleeve 24). At this time, the workpiece slides down onto the free sleeve 62 under the action of gravity, and then slides down along the free sleeve 62 to the outside of the outer shell 1, realizing the removal of the workpiece.

[0051] After the workpiece is removed, the fixed shaft 81 drives the track support frame 31 to return to the top horizontal position, ready for the insertion of the next workpiece.
