Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, specifically a heat treatment furnace for processing coated titanium electrodes that is easy to load. Background Technology

[0002] The heat treatment furnace for coated titanium electrodes is a specialized temperature control device for electrode preparation. The furnace body adopts a sandwich structure of high-temperature resistant alloy and insulation cotton, and has a built-in precise temperature control system with a temperature control accuracy of ±1℃. It supports inert gas atmosphere protection to avoid oxidation of titanium substrate. It can realize processes such as coating curing and crystal phase adjustment. It is suitable for batch or single-piece processing and can significantly improve the adhesion between the coating and the titanium substrate, ensuring the conductivity and corrosion resistance of the electrode. It is the core equipment for mass production of coated titanium electrodes.

[0003] For example, the utility model patent with announcement number CN221192233U discloses a heat treatment furnace for processing coated titanium electrodes. This heat treatment furnace for processing coated titanium electrodes is equipped with three material receiving slots, which can extract the carrier plate from the inside of the furnace body in stages, avoiding the simultaneous opening of the three material receiving slots and reducing the heat loss inside the furnace body. After the carrier plate is extracted from the inside of the furnace body, the baffle can block the material receiving slots, ensuring that the heat loss inside the furnace body is also reduced during material extraction, thereby effectively reducing the heat loss inside the furnace body and improving the energy efficiency of the drying furnace.

[0004] However, this type of heat treatment furnace has the following shortcomings: feeding relies on manually pulling the carrying plate, and only one batch of workpieces can be processed at a time, making continuous operation impossible and batch processing efficiency low; manually pulling the carrying plate is laborious, and relying solely on guide rollers for guidance results in insufficient positioning accuracy, which can easily lead to workpiece displacement; there is no independent transfer structure, and workpieces need to be loaded and unloaded directly next to the furnace body during feeding, which occupies working space and makes it easy for workpieces to be bumped. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a heat treatment furnace for processing coated titanium electrodes that facilitates material loading. It solves the problems of existing devices that rely on manually pulling the carrier plate for loading, which can only process one batch of workpieces at a time, making continuous operation impossible and resulting in low batch processing efficiency; the manual pulling of the carrier plate is laborious, and the positioning accuracy is insufficient due to the reliance on guide rollers alone, which can easily lead to workpiece displacement; and the lack of an independent transfer structure, requiring workpieces to be loaded and unloaded directly next to the furnace body, which occupies working space and makes the workpieces prone to damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat treatment furnace for processing coated titanium electrodes with easy loading, comprising:

[0008] The workbench has two opposing support walls fixedly installed on its upper wall, a suspended ceiling fixedly installed at the top of the two support walls, and a chain hoist fixedly installed on the lower wall of the suspended ceiling.

[0009] Two furnace walls are fixedly installed on the upper wall of the workbench, and heating modules are fixedly installed on their inner walls.

The upper wall of the furnace top is fixedly connected to the drive end of the chain elevator, and auxiliary tilt angles are provided on both sides of the furnace top.

[0011] Two sets of push blocks have sliding inclined surfaces at their driving ends, which are adapted to the auxiliary tilt angle. The connecting ends of the push blocks are fixedly connected to the two support walls by synchronous hydraulic cylinders.

[0012] Preferably, the inner walls of both furnace walls are provided with sliding grooves, and the side walls of both furnace doors are fixedly installed with guide strips, which are slidably adapted to the sliding grooves; the contact surface between the furnace door and the furnace wall is provided with a ceramic sealing strip, which is fixedly connected to the furnace door.

[0013] Preferably, a transfer frame is provided on the workbench, guide rods are fixedly installed at the four corners of the upper wall of the transfer frame, and pulleys are fixedly installed on the lower wall of the transfer frame.

[0014] Preferably, a heat treatment loading platform is fitted onto the four guide rods, and four load-bearing sleeves are fixedly installed on the lower wall of the heat treatment loading platform. The load-bearing sleeves are slidably adapted to the guide rods. A lifting hole is provided on the edge of the upper wall of the heat treatment loading platform.

[0015] Preferably, the connecting end of the guide rod has an assembly chamfer, which is adapted to the load-bearing sleeve.

[0016] Preferably, load-bearing rods are fixedly installed at the four corners of the lower wall of the ceiling.

[0017] Preferably, the workbench has guide angles at both ends, and the guide angles correspond to the positions of the furnace door.

[0018] Beneficial effects

[0019] This utility model provides a heat treatment furnace for processing coated titanium electrodes that facilitates material loading, and has the following beneficial effects:

[0020] By using a transfer frame with pulleys to achieve workpiece turnover, and by sliding the heat treatment loading platform and guide rods to adapt to each other, and by using the suspended furnace door and the worktable guide angle to guide the transfer frame in and out, the problems of continuous loading and low batch efficiency are solved.

[0021] The furnace top is automatically raised and lowered by a chain hoist, and the guide rod of the transfer frame slides and adapts to the load-bearing sleeve of the loading platform. The assembly chamfer guides precise docking, which solves the problems of laborious operation and inaccurate positioning.

[0022] The workpiece can be independently supported by a transfer frame with pulleys, allowing for loading and unloading away from the furnace body. Combined with the smooth entry and exit of the workbench guide angle, this solves the problems of large workspace occupation and easy workpiece collision. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figures 1-4 A heat treatment furnace for processing coated titanium electrodes, which facilitates material loading, includes:

[0030] The workbench 1 has two opposing support walls 2 fixedly installed on its upper wall, and a ceiling 3 fixedly installed on the top of the two support walls 2. A chain hoist 4 is fixedly installed on the lower wall of the ceiling 3.

[0031] Two furnace walls 5 are fixedly installed on the upper wall of the workbench 1, and heating modules 6 are fixedly installed on their inner walls.

[0032] The furnace top 7 has furnace doors 8 fixedly installed on both its front and rear walls. Both sides of the furnace doors 8 are slidably connected to the furnace wall 5. The upper wall of the furnace top 7 is fixedly connected to the drive end of the chain elevator 4, and auxiliary tilt angles 9 are provided on both sides of the furnace top 7.

[0033] Two sets of push blocks 10, each with a sliding inclined surface 11 at its drive end, the sliding inclined surface 11 being adapted to the auxiliary tilt angle 9, and the connecting end of the push block 10 being fixedly connected to the two support walls 2 respectively by synchronous hydraulic cylinders 12.

[0034] In use, the workbench 1 provides basic support for the entire heat treatment furnace, serving as a platform for furnace installation and material loading. The support wall 2 supports the ceiling 3, providing an installation foundation for the chain elevator 4 and protecting the furnace wall 5. The ceiling 3 supports the chain elevator 4, ensuring its stable operation. The chain elevator 4 drives the furnace top 7 to rise and fall, opening and closing the furnace body for convenient material loading and unloading. The furnace wall 5, furnace top 7, and furnace door 8 work together to form a sealed heat treatment chamber, providing space for the heat treatment of coated titanium electrodes. The heating module 6 generates heat when energized, providing the temperature environment required for the heat treatment of coated titanium electrodes. When the furnace top 7 rises and falls, it drives the furnace door 8 to move synchronously, working with the furnace wall 5 to seal the furnace cavity. After the furnace door 8 slides closed, it seals the furnace cavity, reducing heat loss. The auxiliary tilt angle 9 is adapted to the sliding tilt surface 11, converting the thrust of the synchronous hydraulic cylinder 12 into the sliding power of the furnace door 8. When the push block 10 pushes the auxiliary tilt angle 9, it guides the furnace top 7 to move the two furnace doors 8 downwards, improving the sealing performance.

[0035] Please see Figures 2-3 The inner walls of both furnace walls 5 are provided with sliding grooves 13, and the side walls of both furnace doors 8 are fixedly installed with guide strips 14, which slide and adapt to the sliding grooves 13; ceramic sealing strips 15 are provided on the contact surface between the furnace door 8 and the furnace wall 5, and the ceramic sealing strips 15 are fixedly connected to the furnace door 8.

[0036] In use, the slide groove 13 provides sliding guidance for the guide bar 14, standardizing the opening and closing trajectory of the furnace door 8; the guide bar 14 and the slide groove 13 are slidably matched to ensure that the furnace door 8 slides smoothly and avoids jamming; the ceramic sealing strip 15 fills the gap between the furnace door 8 and the furnace wall 5, enhances the sealing of the furnace cavity, reduces heat loss, and is resistant to high temperature, thus extending its service life.

[0037] Please see Figure 4 A transfer frame 16 is provided on the workbench 1. Guide rods 17 are fixedly installed at the four corners of the upper wall of the transfer frame 16, and pulleys 18 are fixedly installed on the lower wall of the transfer frame 16.

[0038] In use, the transfer frame 16 supports the heat treatment loading platform 19 to realize the transfer and loading of workpieces; the guide rod 17 provides lifting guidance for the heat treatment loading platform 19 to ensure accurate movement of the loading platform; the pulley 18 facilitates the movement of the transfer frame 16 on the workbench 1, improving the convenience of loading and transfer.

[0039] Please see Figure 4A heat treatment loading platform 19 is fitted on four guide rods 17. Four load-bearing sleeves 20 are fixedly installed on the lower wall of the heat treatment loading platform 19. The load-bearing sleeves 20 are slidably adapted to the guide rods 17. A lifting hole 21 is opened on the edge of the upper wall of the heat treatment loading platform 19.

[0040] In use, the heat treatment loading platform 19 is used to place coated titanium electrode workpieces to be heat treated, enabling batch loading; the load-bearing sleeve 20 is slidably adapted to the guide rod 17 to guide the heat treatment loading platform 19 to rise and fall smoothly; the lifting hole 21 makes it easy to lift the heat treatment loading platform 19 with a lifting tool, improving the efficiency of loading and unloading workpieces.

[0041] Please see Figure 4 The connecting end of the guide rod 17 is provided with an assembly chamfer 22, which is adapted to the load-bearing sleeve 20.

[0042] When in use, the chamfer 22 guides the load-bearing sleeve 20 to quickly and accurately fit into the guide rod 17, reducing assembly difficulty and improving the installation efficiency of the loading platform.

[0043] Please see Figure 3 , and load-bearing rods 23 are fixedly installed at the four corners of the wall below the ceiling 3.

[0044] When in use, the load-bearing rod 23 enhances the structural strength and load-bearing capacity of the ceiling 3, preventing the ceiling 3 from deforming due to the weight of the chain hoist 4 and the furnace top 7, and ensuring stable operation of the equipment.

[0045] Please see Figure 2 The workbench 1 has guide angles 24 at both ends, and the guide angles 24 correspond to the positions of the furnace door 8.

[0046] In use, the guide angle 24 guides the transfer frame 16 to move smoothly onto the workbench 1. When the first batch of coated titanium electrode workpieces is heat-treated, the operator fixes the second batch of workpieces onto the heat treatment loading platform 19 and moves it to the front of the furnace door 8 via the guide angle 24. After the first batch of coated titanium electrode workpieces cools down, the operator opens the furnace door 8 and moves the heat treatment loading platform 19 of the first batch of coated titanium electrode workpieces out from behind the furnace door 8 along the guide angle 24. The second batch of workpieces is then pushed into the furnace wall 5 for heat treatment. At this time, the first batch of coated titanium electrode workpieces is disassembled and the third batch of coated titanium electrode workpieces is fixed, and this cycle is repeated.

[0047] Example 1, please refer to Figures 1-4 In this embodiment, the batch continuous heat treatment of coated titanium electrodes is achieved through the turnover of the transfer frame, the precise docking of the loading platform, and the multi-batch cyclic operation, which greatly reduces the waiting time and meets the needs of large-scale production of large coated titanium electrode workpieces.

[0048] Specifically, before the operation, the workpiece loading is completed: the coated titanium electrodes to be heat-treated are neatly placed on the heat treatment loading platform 19. With the help of the assembly chamfer 22 at the connecting end of the guide rod 17, the load-bearing sleeve 20 of the loading platform is quickly fitted into the guide rod 17 of the transfer frame 16 to complete the precise assembly. The transfer frame 16 is pushed (the lower wall pulley 18 reduces the moving resistance) and smoothly moved to the front of the furnace body along the guide inclination angle 24 at both ends of the worktable 1, waiting for the material to be loaded.

[0049] Start the chain elevator 4 to drive the furnace top 7 upward, and the furnace doors 8 on both sides of the furnace top move upward accordingly. The guide strips 14 on the side walls of the furnace doors slide smoothly along the sliding grooves 13 of the furnace wall 5 to avoid jamming. Push the transfer rack 16 loaded with workpieces into the working area between the furnace walls 5, ensuring that the heat treatment loading platform 19 is directly below the furnace cavity. Control the chain elevator 4 to drive the furnace top 7 downward, and then start the synchronous hydraulic cylinder 12 to push the push block 10 to move towards the furnace top. The sliding inclined surface 11 of the push block 10 fits with the auxiliary tilt angle 9 of the furnace top, converting the thrust into a downward pressing force on the furnace door 8, so that the furnace door 8 fits tightly against the furnace wall 5. The ceramic sealing strip 15 fills the gaps and enhances the sealing of the furnace cavity.

[0050] The heating module 6 is activated for heat treatment. The temperature control sensor inside the furnace cavity continuously monitors the temperature uniformity. During this process, the operator can load the second batch of workpieces onto another transfer rack 16 and move it to the side of the furnace along the guide angle 24 to wait. After the first batch of workpieces has been heat-treated, the push block 10 is reset, the furnace top 7 is raised, the furnace door 8 is opened, and the transfer rack 16 carrying the finished products is moved out. At the same time, the transfer rack 16 carrying the second batch of workpieces is pushed in, realizing the "heat treatment-loading-unloading" cycle, which greatly improves the efficiency of batch processing.

[0051] Example 2: In this example, the furnace cavity is sealed and insulated, and the equipment is stable, ensuring uniform heat treatment quality of the coated titanium electrode through multiple sealing structures, precise guidance and stable support design.

[0052] Specifically, when the furnace body closes, the chain hoist 4 drives the furnace top 7 to descend smoothly. The load-bearing rod 23 on the lower wall of the suspended ceiling 3 enhances the rigidity of the suspended ceiling structure, preventing deformation during the raising and lowering of the furnace top. The guide strip 14 of the furnace door 8 slides and adapts to the sliding groove 13 of the furnace wall 5, ensuring that the furnace door moves vertically and preventing deviation that could cause sealing gaps. The synchronous hydraulic cylinder 12 drives the push block 10 to move synchronously, and the sliding inclined surface 11 fits tightly with the auxiliary tilt angle 9, generating uniform lateral pressure that pushes the furnace door 8 against the furnace wall 5. The ceramic sealing strip 15 at the contact surface between the furnace door and the furnace wall is compacted, forming a reliable sealing barrier, reducing heat loss during heat treatment and ensuring uniform temperature inside the furnace cavity.

[0053] During heat treatment, the heating module 6 continuously provides stable heat, and the sealed furnace cavity effectively maintains the target temperature, preventing temperature fluctuations from affecting the quality of the electrode coating. The four guide rods 17 of the transfer frame 16 provide stable support for the heat treatment loading platform 19, preventing uneven placement of workpieces from causing the loading platform to tilt. The sliding fit between the load-bearing sleeve 20 and the guide rods 17 ensures accurate positioning of the loading platform within the furnace cavity, preventing workpieces from colliding with the furnace wall. During equipment operation, the rigid connection between the support wall 2 and the ceiling 3, and the auxiliary support of the load-bearing rods 23, ensure the stability of the overall structure and extend the service life of the equipment.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
