Description

Technical Field

[0001] The invention relates to the technical field of silicon steel high-temperature bell-type furnaces, in particular to a silicon steel high-temperature bell-type furnace with a bell body safety interlocking mechanism. Background Art

[0002] In the steel processing process of high-performance machine tool components such as guide rails, silicon steel high-temperature bell-type furnace is a key equipment used for silicon steel heat treatment in the steel processing industry. Its operating temperature is usually above 800°C, and can even reach 1200°C. Silicon steel needs to be precisely annealed in a high-temperature bell-type furnace to optimize performance, and the safety interlock mechanism between the bell body and the furnace table is particularly important.

[0003] In the prior art, an electrically heated hood-type bright annealing furnace, such as that disclosed in publication number CN114150144A, comprises an annealing module, a hoisting module, and a control module. The annealing module comprises a furnace table, an inner cover, an outer cover, and an automatic sealing device. The furnace table is mounted on the ground and is cylindrical, with a base, a fan, and a discharge plate arranged from bottom to top. The discharge plate adopts a stacked structure, with the upper and lower plates both made of annular metal plates. The upper plate is composed of several regular polygons with identical centers, while the lower plate is composed of several circumferentially distributed sectors with through holes. The hoisting module includes a hoisting track and a hoisting machine. The control module is a console located on the side of the annealing module. The console is controlled by a PLC control system and can control the operation of the annealing module and the hoisting module. The console can be controlled by console panel operation and mobile phone remote control. This reduces manpower input, reduces production risks, and improves production efficiency.

[0004] The above-mentioned document adopts an automatic sealing device, which cooperates with the sealing mechanism between the inner cover and the base of the furnace to realize automatic connection sealing. However, during the cooling stage of the hood-type high-temperature furnace, especially the rapid cooling stage, the temperature in the furnace drops rapidly. Due to the thermal expansion and contraction effect, the gas in the furnace will flow turbulently. When the thermal expansion and contraction phenomenon is severe, vortex flow will be generated in local areas, resulting in local negative pressure. The existence of negative pressure will cause the cover and the furnace to be sucked tightly, making it difficult to separate them smoothly. This will not only affect production efficiency and increase the labor intensity of operators, but may also cause damage to the equipment and shorten the service life of the equipment.

[0005] Therefore, the present invention proposes a silicon steel high-temperature bell-type furnace with a bell-type safety interlocking mechanism to solve the problem that the connection between the bell-type furnace and the furnace table of the existing bell-type furnace is difficult to implement multiple joint locking and lacks a quick and safe separation mechanism, causing difficulty in operation.

[0022] Embodiment 2. Refer to the appendix Figure 1-16 , on the basis of Embodiment 1, in order to achieve double combined locking after the preliminary docking of the silicon steel high-temperature bell-type furnace cover 1 and the furnace platform 3: a drive gear group 51 is arranged on the outer surface of one side of the drive ring group 5. The drive gear group 51 is composed of a drive motor and a driven gear. A lining plate is fixedly installed on the outer ring surface of the drive ring group 5. The drive motor is fixedly installed on the upper surface of the lining plate. The driven gear is fixedly installed on the output shaft of the drive motor, and the outer surface of the driven gear is adaptively meshed with the outer surface of the drive ring group 5; the installation groove 300 has a "C"-shaped groove structure. The two ends of the installation groove 300 are movably connected with an adaptive touch plate 32. The outer side of the adaptive touch plate 32 is set as a curved surface adapted to the outer ring surface of the furnace platform 3. Receiving grooves are opened on the inner walls at both ends of the adaptive touch plate 32. An elastic connecting rod 321 is fixedly connected to the inner surface of the receiving groove. The other end of the elastic connecting rod 321 is fixedly connected to the inner wall of the installation groove 300. The height of the adaptive touch plate 32 is slightly higher than the height of the clamping convex block 31, and the outer surface of the adaptive touch plate 32 is adapted to the inner wall of the clamping groove 20; the outer surface of the elastic connecting rod 321 is movably abutted against the inner surface of the inner curved convex plate 52; the height of the elastic connecting rod 321 is adapted to the groove height of the clamping groove 20; In this embodiment, after the silicon steel high-temperature bell-type furnace cover 1 and the furnace platform 3 are limited and docked, the clamping convex block 31 is adaptively inserted into the inside of the clamping groove 20 to achieve axial alignment and clamping. At this time, through the drive of the drive gear group 51, the rotation of the drive ring group 5 is realized.配合驱动环组5内侧环面安装的内曲凸板52,当内曲凸板52转动至安装槽300位置时,参照 Figure 9As shown, the inner curved convex plate 52 squeezes the adaptor touch plate 32, and the adaptor touch plate 32 moves inward under the action of the squeezing force. At this time, the axially docked card slot 20 and the card slot protrusion 31 are radially stabilized for a secondary time. At the same time, the adaptor touch plate 32 can be easily moved when squeezed and released by the inner curved convex plate 52, which not only satisfies the double joint locking of the initially limited card slot 20 and the card slot protrusion 31, but also realizes the filling and compensation of the gap of the installation slot 300 and the card slot 20, and can provide physical protection for the protruding card slot 31, taking into account the locking strength and component protection, avoiding hard contact damage, and achieving the effect of multiple uses of one thing.

[0023] Example 3, refer to the attached Figure 1-16 The locking mechanism 402 of the second embodiment is a kind of locking mechanism that can realize the triple plug-in locking of silicon steel high temperature bell-type furnace cover 1 and furnace platform 3, replaces the step of manual locking, and strengthens safety performance: an interlocking resistance component is provided on the operation base 4, and the interlocking resistance component includes a resistance piece and a counter-plug; an avoidance groove 40 is provided on the upper outer surface of the operation base 4, and the outer surface of the lower curved convex plate 53 is movably connected with the avoidance groove 40, and an operation cavity 400 is provided on the inner surface of the operation base 4; a slide groove 401 is provided on the upper inner wall of the operation base 4, and the resistance piece includes a resistance rod 42, and the upper outer surface of the resistance rod 42 is slidably connected with the inner surface of the slide groove 401, and the upper end of the resistance rod 42 is set to a rounded corner, and the outer surface of the rounded corner is movably abutted with the lower surface of the lower curved convex plate 53, and a limiting support ring is fixedly added to the outer surface of the middle section of the resistance rod 42; the lower end of the slide groove 401 is through-open A buffer groove is provided, the inner diameter of the buffer groove is larger than the inner diameter of the slide groove 401, and a sliding sleeve is provided on the outer surface of the lower side of the interference rod 42, and the upper end of the interference spring 421 is fixedly connected to the top surface of the inner cavity of the buffer groove, and the lower end of the interference spring 421 is fixedly connected to the upper surface of the limit support ring; the counter-plug includes a gear 43 and a locking rod 44, and the gear 43 is rotatably connected to the inner wall of the operating chamber 400 through an axle rod, and a double-sided toothed rod 422 is fixedly installed on the lower end of the interference rod 42, and the outer surface of one side of the double-sided toothed rod 422 meshes and rotates with the outer surface of the gear 43, and the side of the gear 43 away from the double-sided toothed rod 422 meshes and rotates with the outer surface of the locking rod 44, and the locking rod 44 is slidably installed on the operating base 4, and the upper end of the locking rod 44 extends to the outside of the operating base 4, and the outer surface of the locking rod 44 is movably engaged with the inner wall of the lock groove 210; In this embodiment, when the driving ring group 5 is rotated by the driving force, the inner curved convex plate 52 on its inner side reaches the installation groove 300 position, and the adapter touch plate 32 is locked for the second time. At the same time, the lower curved convex plate 53 added at the lower end of the driving ring group 5 just reaches the avoidance groove 40 position. At this time, the lowest point of the lower curved convex plate 53 conflicts with the rounded corner position of the upper end of the interference rod 42. When the lowest point of the lower curved convex plate 53 is just above the interference rod 42, the interference rod 42 moves downward under the squeezing force of the upper end. At this time, the abutment spring 421 is stretched, and the double-sided gear rod 422 moves downward synchronously, and the gear 1 43 and the gear 43 are connected. The double-sided gear rod 422 is adapted to mesh and rotate in the counterclockwise direction, and at this time the locking rod 44 moves upward to insert and lock the locking groove 210 on the upper docking block 21, thereby achieving a triple interlock after the silicon steel high-temperature bell-type furnace cover 1 and the furnace table 3 are docked and installed, and the locking force is evenly distributed. One action realizes the synchronous effects of axial clamping, radial extrusion and plug-in locking, eliminating the risk of axial and radial displacement, without manual intervention, and significantly improving the operational safety in high-temperature environments, avoiding loosening between the silicon steel high-temperature bell-type furnace cover 1 and the furnace table 3, and ensuring a good sealing effect.

[0024] Example 4, refer to the attached Figure 1-16 On the basis of the third embodiment, in order to achieve the sealing performance and high efficiency of the unlocking action after the multiple interlocking of the silicon steel high-temperature bell-type furnace hood 1 and the furnace table 3: a sealing ring 22 is fixedly installed on the lower end of the connecting sleeve 2, and an annular sealing groove 30 is provided on the upper side surface of the furnace table 3. The inner surface of the annular sealing groove 30 is adapted to be embedded with the outer surface of the sealing ring 22, and a bag pressure slow-release component is provided at the lower end of the annular sealing groove 30. The bag pressure slow-release component includes an exhaust pipe 302 and an air-releasing bag ball 303. A reserved arc groove 301 is provided on the inner wall of the outer ring of the furnace table 3. The air-releasing bag ball 303 is arranged on the inner side of the reserved arc groove 301. One side of the air-releasing bag ball 303 is connected with one end of the exhaust pipe 302, and the exhaust pipe 302 extends away from one end of the air-releasing bag ball 303. To the bottom surface of the inner cavity of the annular sealing groove 30; a linkage extrusion piece is provided on the side of the double-sided gear rod 422 away from the gear 1 43, and the linkage extrusion piece includes a gear 2 45, the outer surface of the gear 2 45 is adapted to mesh with the surface of the side of the double-sided gear rod 422 away from the gear 1 43, and the other side of the gear 2 45 is meshed and rotated with a gear 3 46, and the gears 2 45 and 3 46 are rotatably mounted on the inner side of the operating chamber 400, and a swing lever 461 is fixedly mounted on the gear 3 46, and the outer surface of the swing lever 461 is movably abutted against the outer surface of the air release bag 303; the end of the air release bag 303 away from the exhaust pipe 302 extends to the inside of the operating chamber 400 in an expanded state, and the outer surface of the swing lever 461 is movably abutted against the outer surface of the air release bag 303; In this embodiment, the sealing ring 22 at the lower end of the connecting sleeve 2 is adapted to the annular sealing groove 30, which can enhance the sealing performance when the silicon steel high-temperature bell-type furnace cover 1 and the furnace table 3 are installed, and prevent heat loss during high-temperature processing of silicon steel. In the process of disengaging the docking block 21 and the locking rod 44 from the latching action, through the linkage action of the linkage extrusion member, when the top of the contact rod 42 is pressed down by the lower curved convex plate 53, the swing lever 461 swings counterclockwise and moves away from the air release ball 303. At this time, the air release ball 303 is not squeezed, and the air release ball 303 remains in a saturated and expanded state. It is worth noting that When the silicon steel high-temperature bell-type furnace cover 1 needs to be jointly unlocked, the driving ring group 5 is reversed, so that the lower curved convex plate 53 releases the interference restriction on the top of the interference rod 42, so that the interference rod 42 is quickly reset under the elastic action of the abutment spring 421, and at this time the double-sided gear rod 422 moves upward, so that the locking rod 44 is pulled downward, while the gear 2 45 rotates counterclockwise, and the gear 3 46 is adapted to mesh with the gear 2 45, moving clockwise, and driving the swing lever 461 to move upward, squeezing the bottom of the air release bag 303 to achieve gas extrusion; it is worth noting that, referring to Figure 5 As shown, after the air-releasing balloon 303 is squeezed by the swing lever 461, the gas filled in its inner cavity is gradually discharged through the exhaust pipe 302. At this time, the gas enters between the annular sealing groove 30 and the sealing ring 22, quickly destroying the negative pressure environment, so that the cover body and the furnace table are smoothly separated, which greatly shortens the operation time, improves production efficiency, and reduces the labor intensity of the operator.

[0025] Example 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, in order to achieve stable limiting of the rotation of the driving ring assembly 5: a limiting ring plate 41 is fixedly mounted on the upper outer surface of the operating base 4, and the limiting ring plate 41 corresponds to the position of the docking block 21. The side cross-section of the limiting ring plate 41 is a "T"-shaped structure, and the outer surface of the limiting ring plate 41 is movably adapted to the inner surface of the limiting rail groove 50; The limiting ring plate 41 is combined with the operating base 4 to integrate the limiting function of the driving ring group 5 during rotation, and the limiting ring plate 41 is adapted to the limiting rail groove 50 to ensure the stability of the driving ring group 5 during rotation. The limiting ring plate 41 simultaneously assumes the limiting and structural support functions, reducing the system complexity and manufacturing cost, which not only simplifies the device structure, but also improves space utilization and overall performance, achieving the effect of multiple uses of one thing.

[0026] The working principle and use process of the present invention are as follows: First, when heat treating the steel used for the guide rail components of high-performance machine tools, the steel is placed on the furnace table 3 to fix its position. By setting a docking mechanism, when the silicon steel high-temperature bell-type furnace cover 1 is lowered for installation, the calibration frame 12 is aligned with the calibration column 11 to achieve precise docking of the silicon steel high-temperature bell-type furnace cover 1 and the furnace table 3, achieving preliminary limit and preliminary locking to reduce the risk of thermal expansion displacement in a high-temperature environment, ensure the stability of the equipment, and ensure the stability of the silicon steel high-temperature bell-type furnace cover. After the limit docking of 1 with the furnace table 3, the card-mounting protrusion 31 is adapted to be inserted into the inside of the card-mounting groove 20 to realize the axial alignment card connection. At this time, the driving gear set 51 is driven to realize the rotation of the driving ring set 5, and the inner curved convex plate 52 installed on the inner ring surface of the driving ring set 5 is matched. When the inner curved convex plate 52 rotates to the position of the installation groove 300, the inner curved convex plate 52 squeezes the adapting touch plate 32, and the adapting touch plate 32 moves inward under the action of the squeezing force. At this time, the card-mounting groove 20 and the card-mounting protrusion 3 that are axially docked are engaged. 1 performs secondary radial stabilization. When the driving ring assembly 5 is rotated by the driving force, the inner curved convex plate 52 on its inner side reaches the installation groove 300, and performs secondary locking on the adaptor touch plate 32. At the same time, the lower curved convex plate 53 added at the lower end of the driving ring assembly 5 just reaches the avoidance groove 40. At this time, the lowest point of the lower curved convex plate 53 conflicts with the rounded corner position of the upper end of the interference rod 42. When the lowest point of the lower curved convex plate 53 is directly above the interference rod 42, the interference rod 42 moves downward under the squeezing force from the upper end. At this time, the abutment spring 421 is stretched, the double-sided gear rod 422 moves downward synchronously, the gear 1 43 is adapted to mesh with the double-sided gear rod 422, and rotates counterclockwise, and at this time the locking rod 44 moves upward to insert and lock the locking groove 210 on the upper docking block 21, so as to achieve the triple interlocking after the silicon steel high-temperature bell-type furnace cover body 1 and the furnace table 3 are docked and installed, and the axial clamping, radial extrusion and plug-in locking effects are realized in one action, eliminating the risk of axial and radial displacement.

[0027] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
