Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace cooling impeller technology, specifically a cooling impeller device for a vacuum furnace. Background Technology

[0002] The cooling impeller device on the vacuum furnace is a key component of the vacuum furnace cooling system. It is mainly used to rapidly cool the workpieces in the furnace after the heat treatment process is completed to meet specific process requirements (such as performance control after quenching and annealing). It is usually installed in the cooling chamber of the vacuum furnace (or the top or side of the furnace body) and connected to the circulating air duct and the cooling medium (such as gas or liquid) channel. The cooling medium is driven to flow by the rotation of the impeller.

[0003] The impeller is mechanically driven to form a high-speed circulating airflow or liquid flow of the cooling medium. The forced convection heat transfer coefficient is 10 to 100 times higher than that of natural cooling. It can shorten the time for the workpiece to cool from high temperature to room temperature to several minutes to tens of minutes. However, since the airflow generated by the impeller is in a fixed direction, when the local temperature is too high, it is impossible to guide the cooling medium, which has certain limitations in its use. Utility Model Content

[0004] The purpose of this invention is to provide a cooling impeller device for a vacuum furnace, which addresses the problem that the airflow generated by the impeller is in a fixed direction and cannot guide the cooling medium when the local temperature is too high.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling impeller device for a vacuum furnace, comprising a vacuum furnace body, a control panel at one end of the vacuum furnace body, a cooling box at the top of the vacuum furnace body, a mounting frame fixedly installed inside the cooling box, a rotating motor fixedly installed at the top of the mounting frame, an output shaft at the bottom of the rotating motor passing through the mounting frame and fixedly installed with a rotating shaft, and a cooling impeller fixedly installed on the outer periphery of the rotating shaft, a guide vane plate rotatably connected inside the cooling box and directly below the mounting frame, the guide vane plate being symmetrically rotatably connected inside the cooling box, a cavity being formed inside the cooling box, a rotating gear rotatably connected inside the cavity, a rotating shaft fixedly installed at one end of the guide vane plate, the rotating shaft passing through the cavity and fixedly installed with the rotating gear, and an adjusting rack slidably connected inside the cavity, the adjusting rack meshing with the rotating gear.

[0006] As a further improvement of this utility model: a sliding block is slidably connected to one end of the cooling box, and the sliding block is fixedly installed with the adjusting rack through the cavity.

[0007] As a further embodiment of this utility model: a limiting rack is fixedly installed at one end of the cooling box and directly below the sliding block, and a limiting tooth groove is symmetrically opened at the top of the limiting rack. A through groove is opened at the bottom of the sliding block, and a limiting block is slidably connected inside the through groove. The limiting block is adapted to the limiting tooth groove.

[0008] As a further embodiment of this utility model: a reset spring is fixedly installed inside the through groove, and the reset spring is fixedly installed with the limiting block; a connecting rod is slidably connected to the top of the sliding block, and the connecting rod passes through the through groove and is fixedly installed with the limiting block.

[0009] As a further improvement of this utility model, the top of the cooling box is threaded with a mesh plate to block external dust.

[0010] As a further embodiment of this utility model: a support rod is fixedly installed at the bottom of the vacuum furnace body for support, and the support rod is symmetrically fixedly installed at the bottom of the vacuum furnace body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention converts linear motion into circular motion of a rotating gear by pulling a sliding block to drive an adjusting rack, thereby flexibly adjusting the guide vane angle. Simply pulling the sliding block is enough to quickly adjust the guide vane angle and control the flow direction of the cooling medium. The operation is simple, without complicated adjustment steps, and can quickly adapt to different cooling needs, improving the versatility and flexibility of the vacuum furnace cooling system.

[0013] After the sliding block of this utility model is in place, the reset spring automatically pushes the limit block into the limit tooth groove to form a stable lock, preventing the guide vane angle from shifting due to external force. When adjusting, simply pull the connecting rod to easily unlock. The operation is simple, avoiding deviation of the cooling medium flow due to accidental movement, ensuring stable cooling effect, simplifying the maintenance process, and improving the applicability and reliability of the device.

[0024] Reference Figures 1 to 5 A sliding block 15 is slidably connected to one end of the cooling box 4, and the sliding block 15 passes through the cavity 11 and is fixedly installed with the adjusting rack 14.

[0025] The above scheme is adopted: the sliding block 15 is made of 45# steel and forms a clearance fit with the T-shaped sliding groove on the side wall of the cooling box 4. The sliding block 15 is rigidly connected to the adjusting rack 14 by bolts.

[0026] Reference Figures 1 to 5 A limiting rack 16 is fixedly installed at one end of the cooling box 4 and directly below the sliding block 15. The limiting rack 16 has symmetrical limiting grooves 17 at its top. A through groove 18 is provided at the bottom of the sliding block 15. A limiting block 19 is slidably connected inside the through groove 18. The limiting block 19 is adapted to the limiting groove 17. A return spring 20 is fixedly installed inside the through groove 18. The return spring 20 is fixedly installed with the limiting block 19. A connecting rod 21 is slidably connected to the top of the sliding block 15. The connecting rod 21 passes through the through groove 18 and is fixedly installed with the limiting block 19.

[0027] The above scheme is adopted: the limiting rack 16 is made of 40Cr steel and is fixed to the cooling box 4 by countersunk bolts; the limiting block 19 (Cr12MoV material) is interference-fitted with the limiting tooth groove 17; the return spring 20 is made of 65Mn to provide locking force; the connecting rod 21 is welded to the limiting block 19, with knurled surface, and slides with the through hole of the sliding block 15.

[0028] Reference Figures 1 to 5 The top of the cooling box 4 is threaded with a mesh plate 5 to block external dust;

[0029] The above solution is adopted: the mesh plate 5 is made of stainless steel and is connected to the top of the cooling box 4 by a cross countersunk bolt.

[0032] The working principle of this utility model is as follows: When it is necessary to guide the cooling medium to different cooling areas, the sliding block 15 is pulled, and the sliding block 15 drives the adjusting rack 14 fixed to it to slide in the cavity 11. Since the adjusting rack 14 meshes with the rotating gear 13, the linear motion of the adjusting rack 14 is converted into the circumferential rotation of the rotating gear 13. The rotating gear 13 drives the guide vane 10 to rotate inside the cooling box 4 through the rotating shaft 12, thereby realizing the adjustment of the angle of the guide vane 10. By changing the angle of the guide vane 10, the flow direction of the cooling medium can be changed, so that it can be accurately guided to different cooling areas in the vacuum furnace to meet diverse needs. To meet cooling requirements, after the sliding block 15 slides into place, the limiting block 19, under the elastic force of the return spring 20, automatically engages in the limiting tooth groove 17 at the top of the limiting rack 16, forming a mechanical limit to prevent the sliding block 15 from moving accidentally and to ensure that the guide vane plate 10 is fixed at the set angle. If it is necessary to readjust the angle of the guide vane plate 10, pull the connecting rod 21 upward. The connecting rod 21 drives the limiting block 19 to overcome the elastic force of the return spring 20 and exit from the limiting tooth groove 17, releasing the limit on the sliding block 15. At this time, the sliding block 15 can be pulled again to repeat the above adjustment process, so as to achieve flexible adjustment and reliable fixation of the angle of the guide vane plate 10.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
