Description

Technical Field

[0001] This utility model relates to the field of atmosphere high-temperature furnace technology, specifically to an atmosphere-resistant high-temperature experimental furnace. Background Technology

[0002] High-temperature experimental furnaces with atmosphere protection are mainly used for high-temperature heating and heat treatment experiments on materials and parts under protected atmosphere conditions, such as sintering, annealing, tempering, and performance testing. Authorized publication number CN221198032U discloses an atmosphere-protected rotary furnace. It includes an atmosphere furnace, a support structure mounted on the lower wall of the atmosphere furnace, and a rotary structure installed inside the atmosphere furnace.

[0003] The technical solution addresses the issue that, due to structural limitations, atmosphere furnaces can only achieve uniform temperature and gas distribution through airflow. However, the proximity of the heat source remains constant, resulting in uneven heat treatment of workpieces. This is particularly problematic for rotary parts machined on lathes, which require uniform heat treatment around their axis of rotation. Such atmosphere furnaces cannot guarantee the quality of heat treatment for rotary workpieces. This technical solution addresses this by incorporating a support structure and a rotating structure. The support structure provides working space for the rotating structure, while the rotating structure allows the workpieces placed inside the furnace to rotate slowly, thus ensuring uniform heat treatment and improving the quality of heat treatment. However, this solution cannot perform rotational heat treatment on batches of rotary parts, limiting its application and impacting the efficiency of heat treatment for rotary parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-temperature experimental furnace for atmosphere resistance, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature experimental furnace for atmosphere resistance, comprising an upper chamber and a lower chamber. A heating groove is provided on the upper chamber, and heaters are provided on both sides of the heating groove. A door is also hinged to the upper chamber. A batch rotating assembly is provided on the upper chamber. The batch rotating assembly includes a first rotating shaft and multiple second rotating shafts circumferentially distributed outside the first rotating shaft. A first platform is fixedly connected to the first rotating shaft, and a second platform is fixedly connected to each of the second rotating shafts. A rod is welded to the bottom of the first rotating shaft, and the rod is connected to the output shaft of a reduction motor. Fixed bearings are rotatably connected to the bottom of each of the second rotating shafts. A transmission device is provided on the rod that meshes with each of the second rotating shafts.

[0006] Preferably, the batch rotating assembly further includes a groove formed at the bottom of the upper housing, the tops of the first rotating shaft and the second rotating shaft are both located in the heating groove, the bottoms of the first rotating shaft and the second rotating shaft extend through the bottom of the upper housing into the groove, and the fixed bearing is fixedly connected to the top inner wall of the groove.

[0007] Preferably, the batch rotation assembly further includes inspection doors fixedly connected to both sides of the upper housing, with the two inspection doors respectively covering both sides of the groove.

[0008] Preferably, the batch rotation assembly further includes four vertical rods fixedly connected to the inner wall of the top of the groove, the bottom of each of the four vertical rods being connected to the base, and an electric telescopic rod being detachably connected to the top of the base, the output end of which is detachably connected to a reduction motor.

[0009] Preferably, the transmission device includes a sleeve that is slidably fitted onto the insert rod, a drive gear is fixedly connected to the outer wall of the sleeve, a driven gear is uniformly meshed with the outer side of the drive gear in a circumferential manner, the driven gears are respectively fixedly connected to the second rotating shaft, a connecting rod is uniformly fixedly connected to the sleeve in a circumferential manner, the bottom of the connecting rod is connected to the outer ring of the support bearing, and the inner ring of the support bearing is detachably connected to the base.

[0010] Preferably, the bottom of the upper box is inserted into the lower box, and hydraulic telescopic rods are fixedly connected to all four sides of the lower box. Protrusions are fixedly connected to all four sides of the upper box, and the piston rods of the four hydraulic telescopic rods are respectively connected to the protrusions on the four sides.

[0011] This invention provides a high-temperature experimental furnace for atmospheric resistance. Compared with the prior art, it has the following advantages: 1. In this high-temperature experimental furnace for atmosphere resistance, the geared motor drives the insertion rod to rotate, which causes the first rotating shaft to drive the first platform to rotate. The transmission device also drives the second rotating shaft and the second platform to rotate simultaneously, so that rotating parts can be placed on both the first and second platforms. The geared motor is driven to move upward by the electric telescopic rod, so that the first platform can move upward, so that the rotating parts on the first platform are not blocked by the rotating parts on the second platform. This allows the rotating parts on both the first and second platforms to rotate slowly, thereby achieving uniform heat treatment of a batch of rotating parts.

[0012] 2. This high-temperature experimental furnace for atmosphere resistance, by setting up a sleeve, connecting rod and supporting bearing, allows the insertion rod to rise and fall on the sleeve. When the insertion rod rotates through the geared motor, the connecting rod rotates through the supporting bearing, which can guide and support the sleeve, so that the sleeve can rotate with the insertion rod, thereby driving the drive gear to rotate, causing the driven gear to rotate, thus causing both platform one and platform two to rotate.

[0015] 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.

[0016] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A high-temperature experimental furnace for atmosphere resistance includes an upper chamber 1 and a lower chamber 2. A transformer and a high-voltage board are installed inside the lower chamber 2. The bottom of the lower chamber 2 is also provided with casters and directional wheels. A heating groove 3 is opened on the upper chamber 1. Heaters 4 are provided on both sides of the heating groove 3. An atmosphere protection component is installed inside the upper chamber 1. A door 5 is also hinged on the upper chamber 1. A batch rotation component is provided on the upper chamber 1. The batch rotating assembly includes a first rotating shaft 6 and multiple second rotating shafts 7 circumferentially distributed outside the first rotating shaft 6. A first platform 8 is fixedly connected to the first rotating shaft 6, and a second platform 9 is fixedly connected to the second rotating shaft 7. A plug rod 10 is welded to the bottom of the first rotating shaft 6. The plug rod 10 is connected to the output shaft of a geared motor 11. The geared motor 11 drives the plug rod 10 to rotate, which causes the first rotating shaft 6 to drive the first platform 8 to rotate. The bottom of each second rotating shaft 7 is rotatably connected to a fixed bearing 12, so that the second rotating shaft 7 can rotate by being supported by the fixed bearing 12. The plug rod 10 is provided with a transmission device that meshes with the second rotating shaft 7, so that when the plug rod 10 rotates, the second rotating shaft 7 rotates synchronously, causing the first platform 8 and the second platform 9 to rotate. Rotating parts can be placed on the first platform 8 and the second platform 9, and they can rotate slowly.

[0017] The batch rotating assembly also includes a groove at the bottom of the upper housing 1. The tops of the first rotating shaft 6 and the second rotating shaft 7 are both located in the heating groove 3, and the bottoms of the first rotating shaft 6 and the second rotating shaft 7 extend through the bottom of the upper housing 1 into the groove. The first rotating shaft 6, the second rotating shaft 7 and the upper housing 1 are all made of high wear-resistant materials to reduce wear caused by rotation. The fixed bearing 12 is fixedly connected to the top inner wall of the groove, which can fix the fixed bearing 12 and ensure that the first platform 8 and the second platform 9 are both located in the heating groove 3 to achieve heating of the rotating parts.

[0018] The batch rotating assembly also includes inspection doors 21 fixedly connected to both sides of the upper housing 1. The two inspection doors 21 cover both sides of the groove, so that dust and impurities will not enter the groove and will not affect the rotation of the geared motor 11, the first rotating shaft 6 and the second rotating shaft 7.

[0019] The rotating parts on platform 8 will be blocked by the rotating parts on platform 9, thus affecting their heating by heater 4. Therefore, the batch rotating assembly also includes four vertical rods 20 fixedly connected to the inner wall of the top of the groove. The bottom of each of the four vertical rods 20 is connected to the base 19. The top of the base 19 is detachably connected to an electric telescopic rod 18. The output end of the electric telescopic rod 18 is detachably connected to the geared motor 11. When both platforms 8 and 9 are filled with rotating parts, the electric telescopic rod 18 is extended first, causing the geared motor 11 to drive the insertion rod 10 to move upward, thereby causing platform 8 to move upward. That is, the rotating parts on platform 8 are higher than the rotating parts on platform 9, so that the heating of the rotating parts on platform 8 is not affected.

[0020] The transmission device includes a sleeve 13 that is slidably fitted onto the insert rod 10. A drive gear 14 is fixedly connected to the outer wall of the sleeve 13. Driven gears 17 are uniformly and circumferentially meshed with the outer side of the drive gear 14. Driven gears 17 are respectively fixedly connected to the rotating shaft 7. Connecting rods 15 are uniformly and circumferentially fixedly connected to the sleeve 13. When the connecting rods 15 rotate, they do not affect the reduction motor 11 and the electric telescopic rod 18. The bottom of the connecting rods 15 is connected to the outer ring of the support bearing 16, and the inner ring of the support bearing 16 is detachable. Connected to the base 19, the insertion rod 10 can rise and fall on the sleeve 13. When the insertion rod 10 rotates through the reduction motor 11, the connecting rod 15 rotates through the support bearing 16, which can guide and support the sleeve 13, so that the sleeve 13 can rotate with the insertion rod 10, thereby driving the drive gear 14 to rotate, causing the driven gear 17 to rotate, thereby causing the rotating shaft 7 to rotate, and finally causing both the platform 8 and the platform 9 to rotate, rotating the rotating parts on them, so that all surfaces of the rotating parts can be heated by the heater 4.

[0021] Since the geared motor 11 and the electric telescopic rod 18 are both located in the groove, although the inspection door 21 can be removed for maintenance, there is still a problem of limited space. Therefore, a second implementation method was set up.

[0022] The second implementation differs from the first implementation in that the bottom of the upper housing 1 is inserted into the lower housing 2, and hydraulic telescopic rods 22 are fixedly connected to all four sides of the lower housing 2. Protrusions are fixedly connected to all four sides of the upper housing 1, and the piston rods of the four hydraulic telescopic rods 22 are respectively connected to the protrusions on all four sides. The four hydraulic telescopic rods 22 all supply hydraulic oil through the same oil pipe, and the oil level is the same, so that the four piston rods rise at the same time. The upper housing 1 can be raised through the protrusions, thus increasing the space available for maintenance.

[0023] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0024] In use, rotating parts are placed on both platform 8 and platform 9. Platform 8 is then raised so that its rotating parts are not blocked by the rotating parts on platform 9. Next, the chamber door 5 is closed, and the geared motor 11 rotates, causing the insertion rod 10 to drive the sleeve 13 to rotate. This causes the drive gear 14 to drive the driven gear 17 to rotate, making both platforms 8 and 9 rotate slowly. This ensures that all rotating parts in the batch are heated by the heater 4, thus enabling rotational heat treatment of the batch of rotating parts and expanding the application range of the existing atmosphere-resistant high-temperature experimental furnace.
