Description

Technical Field

[0001] The invention relates to the technical field of heating furnaces, in particular to an energy-saving box-type heating furnace. Background Art

[0002] A box-type heating furnace is a heating device with a box-shaped furnace chamber. It is mainly used for heat treatment of metal parts or alloy steel parts in the air. When processing steel plates, the box-type heating furnace generates heat through its internal heating elements to heat the steel plates placed in the furnace chamber. The steel will gradually heat up to the required temperature and maintain it for a period of time to ensure uniform temperature. After the steel is heated, it is usually necessary to maintain a certain temperature in the furnace while taking the steel out of the furnace through a mechanical device for subsequent processing.

[0003] After the steel plate is heated, some existing heating furnaces need to manually open the door to take out the steel plate. During this process, a large amount of heat in the heating furnace will be lost, resulting in the need to start heating again from a lower temperature when heating the next steel plate, thereby increasing the heating time and energy consumption.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing box-type heating furnaces on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1.

When the steel plate body falls to be flush with the first guide frame, the steel plate body will be pushed into the heating furnace. The insulation box can play a sealing role when the heating furnace is opened, effectively preventing the high temperature in the heating furnace from leaking out, helping to maintain a stable temperature environment in the heating furnace, improving the heating efficiency, and avoiding energy waste and safety hazards caused by temperature leakage. The insulation box ensures that the steel plate body can be heated under appropriate temperature conditions immediately after being pushed into the heating furnace, avoiding the need for reheating due to temperature drop, thereby further improving production efficiency and energy utilization.

[0021] 2. The present invention sets a door opening unit and adopts an L-shaped opening and closing method to enable the first sealing door and the second sealing door to operate flexibly and efficiently when opening and closing, thereby avoiding the space limitations and conflicts that may be caused by traditional straight-line opening and closing. Especially in the process of pushing the steel plate body to the heating furnace, it ensures that the first sealing door and the second sealing door will not block the pushing path of the steel plate body, thereby improving the fluency and efficiency of the production process.

[0022] 3. The present invention provides a feeding mechanism to automatically transport the steel plate to the top of the insulation box through a conveyor belt, which not only improves the feeding speed, but also avoids the heavy labor of traditional manual transportation, thereby reducing labor costs and ensuring the safety of workers. It helps to ensure that the steel plate can quickly enter the insulation unit and provide a stable material supply for subsequent processing, thereby improving overall production efficiency.

When the first rotating rod 2112, the second rotating rod 2113, the third rotating rod 2114 and the fourth rotating rod 2115 rotate, the positioning sleeve 2116 and the first supporting plate 2117 and the second supporting plate 2118 on the positioning sleeve 2116 are driven to rotate synchronously. When the first supporting plate 2117 rotates, the support for the bottom of the steel plate body 2119 is cancelled. At this time, the steel plate body 2119 will fall, and one side of the steel plate body 2119 will contact the surface of the deceleration plate 2105. The deceleration plate 2105 will be subjected to the pressure of the falling steel plate body 2119, and the deceleration plate 2105 will be pressed into the positioning groove 2104. The deceleration plate 2105 The spring 2110 is compressed, and the rotation of the deceleration plate 2105 will drive the rotating rod 2109 to rotate in the positioning groove 2104, ensuring the stability of the operation of the deceleration plate 2105. The deceleration plate 2105 can slow down the falling speed of the steel plate body 2119 again, ensuring that the second support plate 2118 can support the bottom of the steel plate body 2119. With the continuous operation of the first rotating rod 2112, the second rotating rod 2113, the third rotating rod 2114 and the fourth rotating rod 2115, the steel plate body 2119 can be dropped to the position of the first limiting groove 2106 in sequence. The first limiting groove 2106 is flush with the first guide frame 2120, and the first limiting groove 2106 can provide space for the steel plate body 2119 to be pushed out.When the steel plate body 2119 falls to the position of the first limiting groove 2106, the support frame 2122 can provide supporting force for the first hydraulic cylinder 2123. The user starts the first hydraulic cylinder 2123 through an external power supply. The telescopic end of the first hydraulic cylinder 2123 drives the positioning plate 2141 to extend. The extension of the telescopic end of the first hydraulic cylinder 2123 drives the positioning plate 2141 to move. The two guide rods 2140 are connected through the positioning plate 2141 for synchronous movement. The guide rods 2140 can guide and support the telescopic end of the first hydraulic cylinder 2123. One end of the two guide rods 2140 can be fixed and limited by the connecting block 2142 to prevent the two guide rods 2140 from detaching from the support frame 2122. As the telescopic end of the first hydraulic cylinder 2123 extends, it will drive the positioning frame 2124 to move forward. The second limiting groove 2108 can provide moving space for the positioning frame 2124. When the positioning frame 2124 moves with the two clamping plates 2138 to the side of the steel plate body 2119 flush with the first limiting groove 2106, the telescopic end of the first hydraulic cylinder 2123 will pause, and the user will start the motor 2125 through an external power supply. The motor 2125 is fixed to the positioning frame 2124 through the positioning block 2152 to ensure the stability of the motor 2125. When the output end of the motor 2125 rotates, it will drive the first gear 2139 on the output end of the motor 2125 to rotate synchronously. The rotation of the first gear 2139 will bring The second gear 2137 on the forward and reverse screw 2135 that is engaged with the dynamic phase rotates, and the rotation of the second gear 2137 drives the forward and reverse screw 2135 to rotate, and the rotation of the forward and reverse screw 2135 drives the two clamping plates 2138 to move in opposite directions, and the two sliding bars 2136 can limit the two clamping plates 2138 to prevent the two clamping plates 2138 from flipping during the movement. When the two clamping plates 2138 fix the steel plate body 2119, the user starts the first hydraulic cylinder 2123 again, and the telescopic end of the first hydraulic cylinder 2123 drives the fixed steel plate body 2119 to move forward, and the fixed steel plate body 2119 is pushed to the first guide through the first limiting groove 2106. The bottom of the steel plate body 2119 will contact the ball 2121 on the first guide frame 2120. As the telescopic end of the first hydraulic cylinder 2123 extends, the steel plate body 2119 will move along the path of the first guide frame 2120. The ball 2121 can reduce the friction of the steel plate body 2119 when it moves. Through the continuous extension of the telescopic end of the first hydraulic cylinder 2123, the steel plate body 2119 can be pushed into the heating furnace body 1 through the second guide frame 2103 for heating. After the steel plate body 2119 enters the heating furnace, the output end of the motor 2125 is turned over, driving the first gear 2139 and the meshing second gear 2137 to rotate in opposite directions, so that the two clamping plates 2138 cancel the fixation of the steel plate body 2119.The two clamping plates 2138 are then taken out of the heating furnace body 1 by contracting the telescopic end of the first hydraulic cylinder 2123. When the steel plate body 2119 is heated, the heated steel plate body 2119 is fixed by extending the telescopic end of the first hydraulic cylinder 2123 and clamping the two clamping plates 2138. The heated steel plate body 2119 is then moved along the path of the second guide frame 2103 and the first guide frame 2120 by contracting the telescopic end of the first hydraulic cylinder 2123. 19 moves to the top of the second support plate 2118 flush with the first limiting groove 2106. At this time, the user starts the second hydraulic cylinder 2144, and the second hydraulic cylinder 2144 is fixed to the bottom of the support frame 2122 through the fixing plate 2143. The user starts the second hydraulic cylinder 2144 through an external power supply, and the telescopic end of the second hydraulic cylinder 2144 will shrink. The telescopic end of the second hydraulic cylinder 2144 will pull the partition 2145 in the feeding chute 2148 to move, and the dovetail block 2145 on the partition 2145 will move. 46 will move along the path of the dovetail groove 2147 on the material chute 2148, so as to move the partition 2145 smoothly. The user moves the cart 2151 to the bottom of the material chute 2148, and then the heated steel plate body 2119 is transported downward by rotating the first rotating rod 2112, the second rotating rod 2113, the third rotating rod 2114 and the fourth rotating rod 2115, so that the heated steel plate body 2119 falls from the groove 2107 and the material chute 2148 to the cart 2151, and then the heated steel plate body 2119 is transported downward by rotating the first rotating rod 2112, the second rotating rod 2113, the third rotating rod 2114 and the fourth rotating rod 2115. 2151 is convenient for workers to transfer the heated steel plate body 2119. After the unloading is completed, the partition 2145 is pushed back into the unloading chute 2148 through the second hydraulic cylinder 2144 to seal the bottom of the insulation box 2149. The side of the unheated steel plate body 2119 in the limit frame 2101 contacts the four limit plates 2102, which can reduce the loss of internal heat when the heating furnace body 1 is opened. By opening the furnace door 2150, it is convenient for workers to enter the insulation box 2149 to check the inside.

[0050] The specific implementation of this embodiment is as follows: when the first sealing door 2202 and the second sealing door 2203 need to be opened, the user can start the second motor 2210 through the external control switch, the second motor 2210 is powered by an external power supply, and the output end of the second motor 2210 drives the first transmission rod 2211 to rotate, and the rotation of the first transmission rod 2211 will drive the two connected first winding drums 2212 to rotate synchronously, and the rotation of the two first winding drums 2212 will reel in the two first steel ropes 2213, and one end of the two first steel ropes 2213 is fixed on the transmission block 2209 of the roller 2207, and the path of the first steel rope 2213 can be changed through the guide pulley 2214, and the movement speed of the first steel rope 2213 can be reduced. The friction force during operation makes the first steel rope 2213 operate more smoothly. The first sealing door 2202 and the second sealing door 2203 can be pulled by winding up the two first steel ropes 2213. As the first sealing door 2202 and the second sealing door 2203 move, the rollers 2207 on the first sealing door 2202 and the second sealing door 2203 gradually move to the right along the path in the first L-shaped frame 2201 and the second L-shaped frame 2218. When the first sealing door 2202 and the second sealing door 2203 move to the turning point of the first L-shaped frame 2201 and the second L-shaped frame 2218, the first sealing door 2202 and the second sealing door 2203 will tilt. When the first sealing door 2202 and the second sealing door 2203 tilt, the transmission column 2208 will rotate at the connection between the first sealing door 2202 and the second sealing door 2203, so as to ensure that the first sealing door 2202 and the second sealing door 2203 can pass through the turning smoothly to prevent jamming.

The second transmission rod 2220 can be limited by the first L-shaped frame 2201 and the second L-shaped frame 2218 to ensure the stability of the second transmission rod 2220 during operation. When the first sealed door 2202 and the second sealed door 2203 are opened, the two second steel ropes 2216 will be pulled to extend, and the extension of the two second steel ropes 2216 will drive the two second winding drums 2215 on the second transmission rod 2220 to rotate. As the second winding drums 2215 rotate,The second steel rope 2216 originally wound on the second winding drum 2215 will be gradually released, and the rotation of the second winding drum 2215 will drive the second transmission rod 2220 to start rotating. The rotation of the second transmission rod 2220 will further drive the first torsion spring 2217 and the second torsion spring 2219 to stretch, thereby storing energy, which can provide power when closing the first sealing door 2202 and the second sealing door 2203.

The surfaces of the two rollers 307 are in contact with the top of the steel plate body 2119. The output end of the fourth motor 310 is fixedly connected to one end of one of the rollers 307, and one end of the two rollers 307 is fixedly connected to a synchronous pulley 308, and the surfaces of the two synchronous pulleys 308 are rotatably sleeved with a synchronous belt 309. By setting up a feeding mechanism 3, the steel plate is automatically transported to the top of the insulation box 2149 through the conveyor belt 304, which not only improves the feeding speed, but also avoids the heavy labor of traditional manual transportation, thereby reducing labor costs, ensuring the safety of workers, and helping to ensure that the steel plate can quickly enter the insulation unit 21, providing a stable material supply for subsequent processing, thereby improving the overall production efficiency.

[0053] The specific implementation of this embodiment is as follows: the user can start the third motor 302 through an external control switch, the third motor 302 is powered by an external power supply, the output end of the third motor 302 drives the roller 303 to rotate, the rotation of the roller 303 drives the conveyor belt 304 to rotate, and the conveyor belt 304 will come into contact with other rollers 303 during the rotation process, thereby driving the other rollers 303 in the mounting frame 301 to rotate, and when the conveyor belt 304 comes into contact with the guide column 306, the conveyor belt 304 will move along the guide column 306. The contour of the guide column 306 moves, thereby guiding the conveyor belt 304 to move in a specific direction, so as to adjust the running direction of the conveyor belt 304. After the conveyor belt 304 is in operation, the staff will place the steel plate body 2119 on the conveyor belt 304, and the baffle plate 305 can block the steel plate on the conveyor belt 304 to ensure that the steel plate will not shift or fall off during transportation. When the steel plate body 2119 moves into the feed trough 311 along with the conveyor belt 304, part of the steel plate body 2119 will enter the four limit plates 210. 2, at this time, the user starts the fourth motor 310 through an external power supply, and the output end of the fourth motor 310 drives the connected roller 307 to rotate, and the rotation of the roller 307 drives the connected synchronous belt wheel 308 to rotate. When the synchronous belt wheel 308 rotates, the synchronous belt 309 also rotates, and friction is generated between the synchronous belt 309 and another synchronous belt wheel 308. When the synchronous belt 309 rotates, the friction force drives the other synchronous belt wheel 308 to rotate, and the rotation of the other synchronous belt wheel 308 drives the corresponding Another roller 307 connected to the steel plate 2119 rotates. When the two rollers 307 rotate at the same time, the surfaces of the two rollers 307 will contact the top of the steel plate body 2119, thereby pushing the steel plate body 2119 to move forward.
