[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] Most bell-type annealing furnaces in the prior art require workers to load and unload materials manually, which cannot achieve continuous operation. This not only leads to low efficiency of annealing processing, but also easily burns workers and is inconvenient to use. In order to solve this technical defect in the prior art, Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment proposes an annealing device for cold-rolled steel plate processing, which can automatically transport the steel plate body 2 to the interior of the electric heating furnace 305 for annealing processing, without the need for manual material placement by the staff. The device has a steel plate body 2 placed on a processing platform 1, and is characterized in that: the processing platform 1 is provided with an annealing treatment mechanism 3 for heating and insulating the steel plate, the interior of the annealing treatment mechanism 3 is provided with an auxiliary limiting mechanism 4 for clamping the steel plate to complete automatic feeding, and the interior of the processing platform 1 is movably installed with a steel plate conveying mechanism 5. After the staff puts the steel plate body 2 on the processing platform 1, it will move to the bottom of the annealing treatment mechanism 3 under the action of the steel plate conveying mechanism 5, and then the auxiliary limiting mechanism 4 will automatically clamp the steel plate body 2 to the interior of the annealing treatment mechanism 3 for annealing processing.

[0030] In order to automatically transport the steel plate vertically and complete automatic feeding, the present embodiment is provided with an annealing treatment mechanism 3. Specifically, the annealing treatment mechanism 3 includes a first guide rail 301 and a second guide rail 302 symmetrically mounted on the processing platform 1. A smooth guide rod 303 is vertically mounted inside the first guide rail 301. A driving assembly 304 is movably mounted inside the second guide rail 302. The driving assembly 304 includes a driving screw rod movably mounted on the second guide rail 302. The driving screw rod and the movable protrusion 307 are threadedly matched. The smooth guide rod 303 and the driving screw rod are in the same plane and parallel to each other. The two movable protrusions 307 are always at the same height. The first guide rail An electric heating furnace 305 is arranged above the guide rail 301 and the second guide rail 302, and a heating cavity 306 is opened at the lower end of the electric heating furnace 305. Movable protrusions 307 are respectively arranged on the smooth guide rod 303 and the driving component 304, and a rectangular plate 308 is arranged between the two movable protrusions 307. When the movable protrusion 307 moves in the vertical direction, the rectangular plate 308 will move synchronously, thereby completing the vertical transportation of the steel plate. The two sides of the rectangular plate 308 are respectively connected to the movable protrusions 307 for rotation. A micro motor for driving the rectangular plate 308 is arranged inside one of the movable protrusions 307. When the micro motor is powered on, the rectangular plate 308 will rotate.

[0031] like Figure 1 As shown, when the steel plate is annealed, first, the steel plate body 2 will be moved to the bottom of the electric heating furnace 305 under the action of the steel plate conveying mechanism 5, and then the rectangular plate 308 will move downward under the action of the driving screw to make the auxiliary limiting mechanism 4 reach the specified position.

[0032] Subsequently, the auxiliary limiting mechanism 4 will clamp and fix the steel plate body 2 on the conveyor mesh belt 504. After clamping, the rectangular flat plate 308 will move upward under the action of the driving screw. At the same time, the rectangular flat plate 308 will flip one hundred and eighty degrees under the action of the micro motor, so that the steel plate body 2 is located above the rectangular flat plate 308.

[0033] Next, the rectangular plate 308 will continue to move upward under the action of the driving screw, thereby transporting the steel plate body 2 to the inside of the heating cavity 306. Subsequently, the electric heating furnace 305 will first heat the steel plate body 2 to a specified temperature and then keep it warm for a certain period of time to complete the annealing process.

[0034] After slow cooling, the rectangular flat plate 308 will move downward, thereby moving the steel plate body 2 out of the heating cavity 306 .

[0035] In this embodiment, an annealing treatment mechanism 3 is provided, and the cooperation between the rectangular plate 308 and the micro motor is utilized. When the rectangular plate 308 is flipped, the steel plate after annealing is automatically transferred to the bottom of the rectangular plate 308. After the annealing of the next steel plate is completed, the previous steel plate is automatically unloaded, and the loading is completed again while unloading, thereby realizing continuous operation without stopping and waiting. Moreover, in this embodiment, an annealing treatment mechanism 3 is provided, and the cooperation between the driving screw and the smooth guide rod 303 is utilized, so that the steel plate body 2 can be automatically transported to the interior of the electric heating furnace 305 for annealing processing, without the need for manual material discharge by the staff, which can effectively improve the efficiency of the annealing processing of the cold-rolled steel plate and prevent the staff from being scalded.

[0036] Embodiment 2

[0037] In order to automatically clamp and transport the steel plates and improve the automation level of the device, such as Figure 1-Figure 5 As shown, on the basis of the first embodiment, the present embodiment is provided with an auxiliary limiting mechanism 4, specifically, the auxiliary limiting mechanism 4 comprises a telescopic support rod 401 symmetrically mounted on the rectangular flat plate 308, a limiting protrusion 402 is fixedly mounted on the telescopic support rod 401, sliding straight rods 403 are respectively arranged around the limiting protrusion 402, a clamping protrusion 404 is detachably mounted on the sliding straight rod 403, a fixed gear rod 405 is arranged on the side of the sliding straight rod 403, a driving gear 406 is movably mounted inside the limiting protrusion 402, the fixed gear rod 405 is meshed with the driving gear 406, and the driving gear When 406 rotates, it will cooperate with the fixed gear rod 405 to make the sliding straight rod 403 move horizontally. A temperature sensor 407 is set inside the limiting protrusion 402. When the telescopic support rod 401 is extended, the steel plate body 2 will be transported to the inside of the heating cavity 306. During the annealing process, the temperature sensor 407 will monitor the temperature of the steel plate body 2 in real time. The temperature sensor 407 is electrically connected to the electric heating furnace 305 through a wire. When the temperature of the steel plate body 2 reaches the preset value, the electric heating furnace 305 will stop heating. Next, the steel plate will slowly cool down synchronously with the electric heating furnace 305.

[0038] According to the above content, after the annealing process is completed, the rectangular plate 308 will move vertically downward and automatically rotate one hundred and eighty degrees during the downward movement, thereby flipping the steel plate body 2 after annealing to the bottom of the rectangular plate 308.

[0039] When the rectangular plate 308 moves down to the specified position, the sliding rod 403 will move outward under the action of the driving gear 406, so that the clamping protrusion 404 is separated from the steel plate body 2. Next, the steel plate body 2 after annealing will fall onto the conveyor mesh belt 504.

[0040] At the same time, the conveyor belt 504 will convey another steel plate body 2 to the bottom of the rectangular flat plate 308. Then, the limiting protrusion 402 will move downward under the action of the telescopic support rod 401 and contact the steel plate body 2. Next, the four sliding straight rods 403 will move synchronously under the action of the corresponding driving gears 406, thereby quickly clamping and fixing the side of the steel plate body 2.

[0041] After clamping, the rectangular flat plate 308 will move upward again, and this process will be repeated until all the steel plate bodies 2 have completed the annealing process.

[0042] This embodiment sets an auxiliary limiting mechanism 4, and utilizes the mutual cooperation between the sliding straight rod 403 and the driving gear 406 to automatically limit and clamp the side of the steel plate body 2, thereby realizing automatic clamping and feeding of the steel plate. There is no need for the staff to manually place the steel plate body 2 on the rectangular flat plate 308, and it is easy to use. Moreover, this embodiment sets an auxiliary limiting mechanism 4, and utilizes the mutual cooperation between the temperature sensor 407 and the limiting protrusion 402 to automatically measure the temperature of the steel plate body 2 in real time during the annealing and heating process. Compared with the method of monitoring the furnace body temperature in the prior art, the node for ending the heating can be more accurately grasped.

[0043] Embodiment 3

[0044] In order to further improve the processing efficiency of annealing and realize continuous operation, such as Figure 1 and Figure 6 As shown, on the basis of the above-mentioned embodiment, the present embodiment is provided with a steel plate conveying mechanism 5. Specifically, the steel plate conveying mechanism 5 includes an installation cavity 501 opened inside the processing platform 1, and a left rotating shaft 502 and a right rotating shaft 503 are symmetrically arranged inside the installation cavity 501. A conveying mesh belt 504 is arranged between the left rotating shaft 502 and the right rotating shaft 503. A driving motor for driving the left rotating shaft 502 is arranged inside the processing platform 1. During the annealing process of the steel plate, the conveying mesh belt 504 will move intermittently under the action of the left rotating shaft 502 and the right rotating shaft 503. The conveying mesh belt 504 is made of high temperature resistant cloth, which can effectively improve the service life of the conveying mesh belt 504.

[0045] This embodiment provides a steel plate conveying mechanism 5 and utilizes the cooperation between the left rotating shaft 502 and the conveying mesh belt 504 to intermittently feed the steel plate body 2, thereby providing favorable protection for the subsequent continuous annealing process.

[0046] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
