Description

Technical Field

[0001] This utility model relates to the field of workpiece heat treatment technology, and in particular to a silicon carbide rod heating device. Background Technology

[0002] Silicon carbide rods, as a non-metallic high-temperature electric heating element, possess numerous advantages, such as high temperature resistance, oxidation resistance, corrosion resistance, stable operation in environments up to 1500℃, rapid heating, long lifespan, minimal high-temperature deformation, ease of installation and maintenance, and good chemical stability. These characteristics make silicon carbide rods ideal as heating elements for vacuum quenching furnaces. They can rapidly raise the temperature inside the vacuum quenching furnace to the required quenching temperature and maintain temperature stability, providing uniform heat to the workpiece and meeting the high-temperature treatment requirements of various materials. Existing vacuum quenching furnaces require the use of a material transport vehicle, typically using sliding tracks laid directly on the ground for the vehicle to move, necessitating manual pushing and offering limited convenience. Furthermore, if the material transport structure is detachably connected to the vacuum quenching furnace, correcting its position during installation is cumbersome; errors can prevent the material from being transported into the furnace. Therefore, a heating device is needed that facilitates workpiece transport, allows for easy separation of the transport structure from the furnace body, and reduces manual intervention.

[0003] Chinese patent document CN221166647U discloses a vacuum quenching furnace, which has a second vertical rod and a first vertical rod respectively installed on the upper ends of a second horizontal rod and two first horizontal rods. A second threaded rod is rotatably connected to the middle of the second vertical rod, and a second threaded block is threadedly connected to the external side of the second threaded rod. First connecting rods are installed on both sides of the second threaded block, and support plates are installed on the side walls of the two first connecting rods. A material discharge groove is installed on the upper end of the two support plates. The first threaded rod is rotatably connected to the middle of the second horizontal rod, and a first threaded block is threadedly connected to the external side of the first threaded rod. The upper end of the first threaded block is fixedly connected to the lower end of the second vertical rod. This structure facilitates the discharge of materials from the heating furnace and ensures safety during material discharge, preventing injury to workers.

[0004] The existing technology has the following problems:

[0005] While the material conveying structure of the aforementioned vacuum quenching furnace facilitates separation from the furnace body and eliminates the need for laying tracks to increase working time, the first and second crossbars only fit against the fixed rod at the lower end of the furnace body. Furthermore, rollers are installed on both sides of the first crossbar. These rollers are not restrained and are prone to shaking during material loading, which can easily lead to difficulties in transporting materials into the furnace body. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5 As shown, a silicon carbide rod heating device includes a vacuum quenching furnace body 1. The inner cavity of the vacuum quenching furnace body 1 is provided with a silicon carbide rod heating structure 4. Support plates 5 are fixedly installed on the left and right sides of the lower end of the vacuum quenching furnace body 1. A docking positioning component 2 is movably connected to the right side of the right support plate 5. An adjustment drive component 3 is movably connected to the top of the docking positioning component 2.

[0028] The docking positioning component 2 includes two positioning plates 21, and docking grooves 22 are provided at the front and rear positions of the bottom right side of the right support plate 5. The outer sides of the two positioning plates 21 are inserted into the inner walls of the two docking grooves 22. A fixing frame 23 is fixedly installed on the right side of the two positioning plates 21, and the lower end of the fixing frame 23 is flush with the lower end of the two support plates 5.

[0029] The adjustment drive assembly 3 includes a protective frame 31. The front side of the protective frame 31 is fixedly installed on the rear side of the fixed frame 23. A horizontal moving structure 32 is movably connected to the inner wall of the protective frame 31. A moving plate 33 is movably connected to the outer wall of the horizontal moving structure 32. A connecting frame 34 is fixedly installed on the front side of the moving plate 33. Slide grooves 35 are provided at the front and rear of the upper end of the fixed frame 23. Vertical plates 36 are slidably connected to the inner walls of the two slide grooves 35. The upper end of the connecting frame 34 is fixedly connected to the middle of the lower end of the vertical plate 36. Limiting grooves are provided at the front and rear of the left side of the vertical plate 36. Slide plates 37 are slidably connected to the inner walls of the two limiting grooves. A matching bracket 38 for the vacuum quenching furnace body 1 is fixedly installed at the front and rear of the left side of the slide plate 37.

[0030] The docking positioning component 2 facilitates the connection and separation of the material transport structure from the vacuum quenching furnace body 1. Workers do not need to lay tracks on the ground; they simply insert the two positioning plates 21 into the corresponding docking slots 22. Automatic locking and positioning are achieved through the engagement of the arc-shaped clamping plate 26 with the rounded corners at the lower end of the positioning plate 21, requiring no additional tools. Furthermore, the fixed frame 23 and protective frame 31 are in direct contact with the ground, providing a degree of stability. Workers can also install the fixed frame 23 using the mounting holes and bolts on the fixed block 210 as needed, ensuring the stability of the entire material transport structure. Adjusting the drive component 3 allows for the horizontal and vertical movement of the two material-holding inserts 38, enabling them to deliver the material onto the internal support of the vacuum quenching furnace before being lowered and removed. This process is highly automated, reducing manpower. Moreover, the protective frame 31 and protective frame 39 both protect the drive structure, reducing the frequency of manual maintenance and enhancing practicality.

[0031] like Figure 4 As shown, rectangular grooves 24 are provided on the opposite sides of the inner walls of the two docking grooves 22. Guide blocks 25 are slidably connected to the inner walls of the two rectangular grooves 24. Symmetrically arranged arc-shaped clamping plates 26 are fixedly installed on the opposite sides of the two guide blocks 25. The right side of the opposite sides of the two arc-shaped clamping plates 26 are arc-shaped surfaces. The opposite sides of the lower ends of the two positioning plates 21 abut against the arc-shaped surfaces of the two arc-shaped clamping plates 26.

[0032] When the positioning plate 21 is inserted, its rounded lower end presses against the arc-shaped surface of the arc-shaped clamping plate 26, causing the arc-shaped clamping plate 26 to move away from the docking groove 22, and the guide block 25 compresses the spring 29. After insertion, the spring 29 returns to its original position and pushes the arc-shaped clamping plate 26 into the fixing groove 27 of the positioning plate 21, achieving locking and preventing the positioning plate 21 from loosening. This allows for the positioning of the fixing frame 23, eliminating the need to lay tracks on the ground beforehand for the feeding structure of the vacuum quenching furnace.

[0033] like Figure 4 As shown, each of the two positioning plates 21 has a fixing groove 27 for a matching arc-shaped card plate 26 on the side away from each other, and the lower ends of the two positioning plates 21 have rounded corners on the side away from each other.

[0034] like Figure 4 As shown, a pull rod 28 is fixedly installed in the middle of the two guide blocks 25 on the side away from each other, passing through the front and rear of the right support plate 5. A spring 29 is movably sleeved on the side of the outer wall of the two pull rods 28 that is close to each other. The opposite ends of the two springs 29 are fixedly connected to the side of the two guide blocks 25 that is away from each other, and the opposite ends of the two springs 29 are fixedly connected to the inner wall of the two rectangular grooves 24.

[0035] like Figure 3As shown, several fixing blocks 210 with mounting holes are fixedly installed on the bottom front side of the fixing frame 23 and the bottom rear side of the protective frame 31.

[0036] Workers can use the mounting holes on the fixing block 210 to further secure the fixing frame 23 with bolts.

[0037] like Figure 5 As shown, a protective frame 39 is fixedly installed on the middle right side of the vertical plate 36. Slide rails 310 are fixedly installed on the front and rear sides of the inner wall of the protective frame 39. A rack 311 is slidably connected to the inner wall of the two slide rails 310. A motor 312 with a self-locking function is fixedly installed on the bottom front side of the protective frame 39. The output end of the motor 312 passes through the front of the protective frame 39 and is fixedly sleeved with a gear 313. The outer surface of the gear 313 meshes with the right side of the rack 311.

[0038] The output end of the motor 312 can drive the gear 313 to rotate. The rack 311 drives the drive plate to move by meshing with the gear 313. The drive plate can drive the slide plate 37 to move vertically. When the two inserts 38 transport the material on their tops to the vacuum quenching furnace body 1, the inserts 38 are spaced apart from the support inside the furnace. At this time, the two inserts descend through the slide plate 37 and the material can be placed on the support.

[0039] like Figure 5 As shown, a drive plate is fixedly installed on the left side of the rack 311. The left side of the drive plate is fixedly connected to the middle right side of the slide plate 37. A through slot 314 for the matching drive plate is opened through the middle left side of the vertical plate 36.

[0040] The working principle of this utility model is as follows: During use, the silicon carbide heating structure 4, located within the inner cavity of the vacuum quenching furnace body 1, is the core heating component. It generates heat through electrical current to achieve heating in a vacuum environment. The docking positioning assembly 2 connects the vacuum quenching furnace body 1 to the external support structure, ensuring installation stability. The adjustment drive assembly 3 uses mechanical transmission to load and unload materials, reducing manual intervention. When conveying materials to the vacuum quenching furnace, workers do not need to lay tracks on the ground; they only need to insert the two positioning plates 21 into the corresponding docking slots 22. When the positioning plate 21 is inserted, its lower rounded corner presses against the arc-shaped surface of the arc-shaped clamping plate 26, causing the arc-shaped clamping plate 26 to move away from the docking slot 22, and the guide block 25 compresses the spring 29. After insertion, the spring 29 resets, pushing the arc-shaped clamping plate 26 into the fixing slot 27 of the positioning plate 21, achieving locking and preventing the positioning plate 21 from loosening. This achieves the positioning of the fixing frame 23. Secondly, workers can also install the fixing frame 23 using the mounting holes and bolts on the fixing block 210 as needed, thus achieving the stability of the entire material conveying structure. During material feeding, the furnace door of the vacuum quenching furnace is opened. The furnace door is controlled by an electrically driven structure, and the motor 312 is started using an external control system. The output of the motor 312 drives the gear 313 to rotate. The rack 311, through meshing with the gear 313, drives the drive plate to move. The drive plate drives the slide plate 37 to move vertically. When the two inserts 38 transport the material at their tops into the vacuum quenching furnace body 1, the inserts 38 are spaced apart from the supports inside the furnace. At this time, the two inserts descend via the slide plate 37, allowing the material to be placed on the supports. The combined action of the horizontal moving structure 32 and the motor 312 achieves material transfer. Furthermore, the protective frame 31 and the protective frame 39 both protect the drive structure, reducing the frequency of manual maintenance of the mechanical structure and enhancing practicality.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
