Description

Technical Field

[0001] This utility model relates to the field of spheroidizing annealing furnace technology, and in particular to an adjustable spheroidizing furnace. Background Technology

[0002] A spheroidizing furnace, also known as a spheroidizing annealing furnace, is suitable for hardware and special steel enterprises producing high-quality specialty products. Carbon tool steel, alloy tool steel, and bearing steel spheroidized and annealed in this furnace achieve the required mechanical and physical properties, improving plasticity, reducing residual stress, and enhancing the homogeneity of microstructure and composition. The treated products exhibit no oxidation or decarburization, have a uniform spheroidized microstructure, and possess excellent processing and performance characteristics.

[0003] Existing technologies, such as Chinese Patent Publication No. CN210237707U, disclose a spheroidizing annealing furnace, including a furnace body with a receiving cavity inside. Heating wires are installed on the inner wall of the furnace body. An opening is located at the top of the furnace body, and a furnace cover is installed on the opening. An upper fan is installed on the side of the furnace cover facing the receiving cavity. The furnace cover also has a guide plate located below the upper fan. The guide plate has several annular guide grooves, the width of which gradually decreases with distance from the center. The receiving cavity of the furnace body is mainly used to place workpieces. After the workpieces are placed, the furnace cover is closed, heating is performed by the heating wires, and the upper fan is activated. The airflow generated by the fan passes through the annular guide grooves on the guide plate. Since the fan's airflow is stronger in the center and weaker around the edges, the width of the annular guide grooves decreases closer to the center. This ensures that the airflow is relatively uniform across all locations, resulting in more even heating of the workpieces within the entire receiving cavity. However, this utility model does not take into account the differences in size and shape of the workpiece itself. Although the fixed guide groove can ensure that the air volume output by the fan in the middle and around is consistent, it cannot ensure that the air volume received by different surfaces of the workpiece is consistent.

[0004] To address the issue of the difficulty in adjusting fan airflow in spheroidizing furnaces to uniformly cool workpieces, most existing equipment uses fans installed at the top or bottom of the furnace to conduct air and cool the workpieces. However, the direct airflow from the fan is uneven, and the different sizes and shapes of the workpieces cause uneven heating on the workpiece surface, making it particularly inconvenient for annealing precision parts. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that it is inconvenient to adjust the fan airflow in the spheroidizing furnace to uniformly cool the workpiece, and to propose an adjustable spheroidizing furnace.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable spheroidizing furnace, comprising a furnace body, a furnace cover, a motor, a fan, and an adjusting device. The furnace cover is disposed on the top surface of the furnace body, the motor is fixedly mounted on the top surface of the furnace cover, the fan is fixedly connected to the output end of the motor, the adjusting device is disposed on the surface of the furnace cover, the adjusting device includes a protective cover, the protective cover is fixedly connected to the bottom surface of the furnace cover, a guide groove is formed on the surface of the protective cover, a fixed shaft is fixedly connected to the surface of the protective cover, a first diverter plate is fixedly connected to the surface of the fixed shaft, a first diverter groove is formed on the surface of the first diverter plate, a second diverter plate is slidably connected to the surface of the fixed shaft, a second diverter groove is formed on the surface of the second diverter plate, an anti-detachment disc is fixedly connected to the bottom surface of the fixed shaft, a movable disc is slidably connected to the surface of the fixed shaft, a spring is sleeved and connected to the surface of the fixed shaft, one end of the spring is fixedly connected to the surface of the anti-detachment disc, and the other end of the spring is fixedly connected to the surface of the movable disc.

[0007] Furthermore, the fan is located inside the protective cover, a locking block is fixedly connected to the surface of the fixed shaft, and a slot is opened on the surface of the second diverter plate, with the locking block and the slot being locked together.

[0008] Furthermore, the number of card blocks is multiple and evenly distributed, and the number of card slots is multiple and evenly distributed.

[0009] Furthermore, the first diversion channel is matched with the second diversion channel, and the surface of the second diversion plate is provided with grooves, the number of which is two sets and they are arranged symmetrically.

[0010] Furthermore, the surface of the furnace cover is provided with an auxiliary device, which includes a base and a turntable. The turntable is rotatably connected to the inner wall of the base, and a bracket is fixedly connected to the surface of the turntable. A hydraulic rod is fixedly installed on the surface of the bracket, and the furnace cover is fixedly connected to the drive end of the hydraulic rod.

[0011] Furthermore, a collar is slidably connected to the surface of the turntable, a handwheel is fixedly connected to the surface of the collar, and an L-shaped plate is fixedly connected to the surface of the collar.

[0012] Furthermore, the base has a positioning groove on its surface, the L-shaped plate is engaged with the surface of the positioning groove, the turntable has a clearance groove on its surface, and the L-shaped plate is slidably connected with the surface of the clearance groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an adjustment device, when the motor is started to make the fan rotate for air conduction, the airflow of the fan is small in the middle and large in the outer diameter, and the workpieces are of different sizes and shapes, which makes the workpieces easy to be heated unevenly. Before covering the furnace lid, the second diverter plate can be held in the groove and pulled down along the fixed axis, pushing the movable plate downward and compressing the spring at the same time. When the second diverter plate moves to the point where the locking block disengages from the slot, the second diverter plate can be rotated to an appropriate position so that the second diverter groove intersects with the first diverter groove, thereby adjusting the airflow through the first and second diverter plates. After the adjustment is completed, the second diverter plate is released, and the second diverter plate is reset under the action of the spring rebound. The locking block re-locks into the slot to prevent the second diverter plate from rotating arbitrarily. By setting an adjustment device, the output airflow of the middle and outer diameter of the fan can be adjusted according to the situation by using the cooperation of the first and second diverter grooves, so as to avoid uneven heating of the workpieces during annealing, thus effectively improving the applicability of the equipment.

[0015] 2. In this utility model, by setting an auxiliary device, the furnace cover can be opened and closed by activating the hydraulic rod. The handwheel can be held to lift the collar, allowing the L-shaped plate to slide completely into the clearance groove and disengage from the positioning groove. Then, the handwheel is rotated to make the collar and L-shaped plate drive the turntable to rotate, causing the bracket to drive the furnace cover to rotate away from the furnace body, which facilitates the placement of workpieces into the furnace body and the adjustment of the second diverter plate. After the operation is completed, the handwheel is held and rotated in the opposite direction. When the L-shaped plate is aligned with the positioning groove, the furnace cover is just above the furnace body. The handwheel is released to allow the L-shaped plate to re-enter the positioning groove, preventing the turntable from rotating arbitrarily. By setting an auxiliary device, the furnace cover can be rotated away from the furnace body, which facilitates the placement of workpieces into the furnace body and the adjustment of the second diverter plate, thus effectively improving the convenience of the equipment.

[0026] The effects achieved by the above components are as follows: the protective cover 501 is set to prevent the fan 4 from being exposed; the guide groove 502 is set to facilitate the air blown out by the fan 4 to enter the furnace body 1 through the protective cover 501; the first diversion plate 504, the first diversion groove 505, the second diversion plate 506, and the second diversion groove 507 are set to change the air volume between the middle and the periphery of the fan 4 by using the adjustable degree of diversion groove 505 and the second diversion groove 507; the anti-detachment plate 508 is set to prevent the second diversion plate 506 from detaching from the fixed shaft 503; and the movable plate 509 and the spring 510 are set to facilitate both the rotation of the second diversion plate 506 and the reset of the second diversion plate 506.

[0027] Specifically, the fan 4 is located inside the protective cover 501, the surface of the fixed shaft 503 is fixedly connected to the locking block 511, and the surface of the diverter plate 506 is provided with a slot 512, and the locking block 511 is locked to the surface of the slot 512.

[0028] The effect achieved by the above components is that the slot 512 and the block 511 are set to fix the diverter plate 506 and prevent it from rotating at will.

[0029] Specifically, there are multiple card blocks 511 that are evenly distributed, and multiple card slots 512 that are evenly distributed.

[0030] The effect achieved by the above components is that multiple locking blocks 511 and slots 512 are provided so that the splitter plate 506 can be rotated at multiple angles and fixed so as to adjust the air volume of the fan 4 in the middle and around as needed.

[0031] Specifically, the first diversion channel 505 is matched with the second diversion channel 507, and the surface of the second diversion plate 506 is provided with grooves 513. There are two sets of grooves 513, which are arranged symmetrically.

[0032] The effect achieved by the above components is that the groove 513 is provided to facilitate gripping the second distributor plate 506 for rotation.

[0033] Specifically, the surface of the furnace cover 2 is provided with an auxiliary device 6, which includes a base 61 and a turntable 62. The turntable 62 is rotatably connected to the inner wall of the base 61. A bracket 63 is fixedly connected to the surface of the turntable 62. A hydraulic rod 64 is fixedly installed on the surface of the bracket 63. The furnace cover 2 is fixedly connected to the drive end of the hydraulic rod 64.

[0034] The effects achieved by the above components are as follows: the turntable 62 is set to facilitate the rotation of the furnace cover 2 away from the top of the furnace body 1 so as to put the workpiece into the furnace body 1 and adjust the flow divider 506; the hydraulic rod 64 is set to facilitate the opening and closing of the furnace cover 2.

[0035] Specifically, a collar 65 is slidably connected to the surface of the turntable 62, a handwheel 66 is fixedly connected to the surface of the collar 65, and an L-shaped plate 67 is fixedly connected to the surface of the collar 65.

[0036] The effects achieved by the above components are as follows: the handwheel 66 is provided to facilitate the rotation of the collar 65, and the L-shaped plate 67 is provided to cooperate with the positioning groove 68 and the clearance groove 69 to facilitate the fixing and moving of the turntable 62.

[0037] Specifically, the surface of the base 61 is provided with a positioning groove 68, and the L-shaped plate 67 is engaged with the surface of the positioning groove 68.

[0039] Working principle: When the fan 4 rotates by starting the motor 3 with the adjustment device 5 to conduct air, the air force of the fan 4 is small in the middle and large in the outer diameter. Since the workpieces are of varying sizes and shapes, the workpieces are prone to uneven heating. Before covering the furnace lid 2, the second diverter plate 506 can be held in the groove 513 and pulled downwards along the fixed shaft 503, pushing the movable disc 509 downwards while simultaneously compressing the spring 510. When the second diverter plate 506 moves until the locking block 511 disengages from the slot 512, the second diverter plate 506 can be rotated to the appropriate position so that the second diverter groove 507 is aligned with the... The flow dividers 505 are staggered to adjust the airflow through the first flow divider 504 and the second flow divider 506. After adjustment, the second flow divider 506 is released and reset under the action of the spring 510. The locking block 511 re-engages into the locking slot 512 to prevent the second flow divider 506 from rotating arbitrarily. By setting the adjustment device 5, the output airflow of the fan 4 in the middle and outer diameters can be adjusted according to the situation using the cooperation of the first flow divider 505 and the second flow divider 507, so as to avoid uneven heating of the workpiece during annealing. This effectively improves the applicability of the equipment.

[0040] Furthermore, by setting up an auxiliary device 6, the hydraulic rod 64 can be activated to open and close the furnace cover 2. By holding the handwheel 66, the collar 65 can be lifted, allowing the L-shaped plate 67 to slide completely into the clearance groove 69 and disengage from the positioning groove 68. Then, by rotating the handwheel 66, the collar 65 and the L-shaped plate 67 drive the turntable 62 to rotate, causing the bracket 63 to drive the furnace cover 2 to rotate away from the furnace body 1, making it easier to put workpieces into the furnace body 1 and adjust the second diversion plate 506. After the operation is completed, hold the handwheel 66 and rotate it in the opposite direction. When the L-shaped plate 67 is aligned with the positioning groove 68, the furnace cover 2 is just above the furnace body 1. Release the handwheel 66 to allow the L-shaped plate 67 to re-lock into the positioning groove 68, preventing the turntable 62 from rotating arbitrarily. By setting up the auxiliary device 6, the furnace cover 2 can be rotated away from the furnace body 1, making it easier to put workpieces into the furnace body 1 and adjust the second diversion plate 506, which effectively improves the convenience of the equipment.
