Description

Technical Field

[0001] This invention relates to the field of metal sheet processing technology, specifically to a continuous annealing equipment for composite metal sheets. Background Technology

[0002] Metal sheet annealing equipment is a specialized device used for annealing metal sheets. By controlling process parameters such as heating temperature, holding time, and cooling rate, it eliminates the internal stress generated by rolling, stamping, and other processing of metal sheets, improves the microstructure of the material, reduces hardness, increases plasticity and toughness, and optimizes processing performance. It is widely used in aerospace, automobile manufacturing, electronic components and other industrial fields.

[0003] A search revealed Chinese Patent Publication No. CN112899446B, which discloses a continuous annealing device for metal sheet composites. The device includes an annealing furnace, comprising a furnace bottom and a furnace body. The furnace body is fixedly welded to the top surface of the furnace bottom. Inside the furnace body are multiple equidistantly distributed sheet placement mechanisms. Each sheet placement mechanism includes a U-shaped plate with a groove at its bottom. A square rod is fixedly welded to the top of the U-shaped plate, and multiple equidistantly distributed elastic telescopic rods are fixedly connected to the bottom of the square rods. U-shaped clamps are fixedly connected to the bottom ends of the elastic telescopic rods. A metal sheet is clamped between the groove and the U-shaped clamps, with the bottom end of the metal sheet clamped within the groove. This invention overcomes the shortcomings of existing technologies, such as the high temperature at the top opening of a large heating furnace and the significant weight of the sheet material, making manual removal of the sheet material from the top opening of the heating furnace extremely difficult. The invention offers significant advantages and is suitable for widespread application.

[0004] However, in this application, after the metal sheet is annealed, a cover is used to lift multiple sheet placement mechanisms out of the annealing furnace. This requires that the metal sheets being annealed be of the same type. If different metal sheets are annealed at the same time, the required annealing time will be different. When some metal sheets are annealed and taken out, the remaining sheets will also be taken out, thus affecting the annealing effect of the remaining metal sheets. Therefore, it is not convenient to anneal different metal sheets at the same time. Summary of the Invention

[0009] As a preferred embodiment of the present invention, a limiting plate is fixedly connected to the rear wall of each of the plurality of movable plates, and the size of the limiting plate is larger than the size of the movable plate.

[0010] As a preferred embodiment of the present invention, the placement mechanism includes sliding grooves, with multiple sliding grooves formed on both sides of the front wall of the connecting frame and extending into the interior of the cabinet. Slide plates are slidably connected within each of the multiple sliding grooves. Grooves are formed on the upper part of the adjacent sides of the slide plates on both sides, and through grooves are formed on the lower part of the adjacent sides of the slide plates on both sides. The ends of multiple insert rods away from the connecting plate extend into the grooves. Connecting strips are slidably connected within each of the multiple slide plates. One end of multiple springs is fixedly connected to the opposite side of each of the connecting strips on both sides, and the other end of each of the multiple springs is fixedly connected to the inner wall of the slide plate. Placement plates are fixedly connected to the adjacent sides of each of the connecting strips on both sides.

[0011] As a preferred embodiment of the present invention, a plurality of guide rods are passed through the middle of the plurality of connecting strips, both ends of the plurality of guide rods are fixedly connected to the inner wall of the slide plate, and the plurality of springs are sleeved on the outer periphery of the guide rods.

[0012] As a preferred embodiment of the present invention, each of the front walls of the skateboard on one side is fixedly connected to one end of a connecting rod, and the other ends of the plurality of connecting rods are fixedly connected to the front wall of the skateboard on the other side.

[0013] In a preferred embodiment of the present invention, the adjustment mechanism includes a moving groove, a plurality of moving grooves being formed on the front side of the top wall of the moving plate, the rear ends of the plurality of moving grooves penetrating to the inner front wall of the moving plate, the top ends of the plurality of moving grooves being provided with evenly distributed slots, the inner sides of the plurality of moving grooves being slidably connected to fixed rods, the inner sides of the plurality of fixed rods being slidably connected to connecting rods, the top ends of the plurality of connecting rods penetrating to the top wall of the fixed rods and being fixedly connected to locking blocks, the plurality of locking blocks being engaged in the slots, and the rear ends of the plurality of fixed rods penetrating to the rear ends of the moving grooves and being fixedly connected to supporting plates.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the servo motor in the annealing mechanism drives the bidirectional screw to extend the insert rods on both sides and insert them into the connecting frame. At this time, the hydraulic cylinder can drive the connecting frame to move. When the connecting frame moves, the insert rods can drive the corresponding connected moving plate forward, so that the moving plate and the metal plate placed in the moving plate can be removed from the cabinet and replaced. Thus, when different metal plates are annealed at the same time, the metal plate that has been annealed in advance can be removed from the cabinet without affecting the annealing of the other metal plates. When the moving plate moves forward, the insert rods will drive the slide plate in the placement mechanism to move forward as well. Therefore, when the annealed metal plate is completely removed from the cabinet, it will also drive the slide plate to be pulled out of the slide groove and push the placement plate outward. At this time, the operator can drive the locking block in the adjustment mechanism to move the support plate away from the bottom surface of the metal plate and let the metal plate fall onto the corresponding lower placement plate, so as to facilitate the quick removal of the annealed metal plate, so that it can be cooled or transferred by the operator, thereby improving the annealing efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-10 The technical solution provided by this invention specifically includes the following embodiments: Example: A continuous annealing equipment for composite metal sheets includes a cabinet 1, an annealing mechanism 2 is provided inside the cabinet 1, placement mechanisms 3 are provided on both sides inside the cabinet 1, and an adjustment mechanism 4 is provided inside the annealing mechanism 2. The annealing mechanism 2 includes a hydraulic cylinder 201, which is fixedly connected to the top wall of the cabinet 1. A connecting frame 202 is fixedly connected to the output end of the cabinet 1. Multiple through slots 203 are provided on the front wall of the cabinet 1. Movable plates 204 are slidably connected in each of the multiple through slots 203. A chamber 212 is provided in the front part of each of the multiple movable plates 204. A servo motor 205 is fixedly connected to one side of the front part of each of the multiple movable plates 204. The output ends of the multiple servo motors 205 pass through the chamber 212 and are fixedly connected to a bidirectional screw 206. Both ends of the multiple bidirectional screws 206 are threadedly connected to a connecting plate 207. Insert rods 209 are fixedly connected to the opposite sides of the two connecting plates 207. The ends of the multiple insert rods 209 away from the connecting plate 207 pass through the connecting frame 202.

[0021] By activating the servo motor 205, the bidirectional screw 206 at the output end can be rotated. When the bidirectional screw 206 rotates, it can cause the connecting plates 207 on both sides to move closer or further away along the bidirectional screw 206. When the connecting plates 207 move, they can cause the insert rods 209 to move accordingly. When the insert rods 209 on both sides extend, they will be inserted into the connecting frame 202. At this time, the hydraulic cylinder 201 can drive the connecting frame 202 fixed at the output end to move. When the connecting frame 202 moves forward, it can move the insert rods 209. 09 drives the corresponding connected movable plate 204 to move forward, thereby enabling the movable plate 204 and the metal plate placed inside the movable plate 204 to be moved out of the cabinet 1. This allows for flexible adjustment of different numbers of movable plates 204 to be moved out of the cabinet 1 simultaneously without affecting the effect of the remaining movable plates 204. When the movable plate 204 is reset, it can either drive multiple movable plates 204 to reset simultaneously through the connecting frame 202, or remove the limit of the plug rod 209 and the connecting frame 202 and push the movable plate 204 to reset individually.

[0022] Each of the inner sidewalls of multiple chambers 212 has a limit rod 208 fixedly connected to one end, and the other end of each limit rod 208 passes through two connecting plates 207 and is fixedly connected to the other sidewall of the chamber 212.

[0023] By setting a limit rod 208, the connecting plate 207 can be limited, so that the bidirectional screw 206 will not drive the connected connecting plate 207 to rotate when it rotates. Therefore, when the bidirectional screw 206 rotates, the connecting plate 207 can be moved normally along the bidirectional screw 206.

[0024] A control panel 213 is fixedly connected to the side wall of the cabinet 1. A control board 214 is fixedly connected to the front wall of the control panel 213. Multiple heating tubes 211 are fixedly connected to the inner rear wall of the cabinet 1. The front ends of the multiple heating tubes 211 are all fixedly connected to the inner front wall of the cabinet 1.

[0025] The annealing equipment can be easily controlled by the staff by the control board 214; since multiple heating tubes 211 are evenly distributed on the upper and lower sides of multiple moving plates 204, the metal plates in the moving plates 204 can be evenly heated by the heating tubes 211 when the moving plates 204 move the metal plates in the cabinet 1.

[0026] Multiple movable plates 204 are fixedly connected to the rear wall of a limiting plate 210, the size of which is larger than that of the movable plate 204.

[0027] By setting a limiting plate 210, the limiting plate 210 can be driven to move forward when the moving plate 204 moves forward. Since the size of the limiting plate 210 is larger than the size of the moving plate 204, the limiting plate 210 can limit the moving plate 204, preventing the moving plate 204 from being completely pulled out of the cabinet 1. At the same time, the limiting plate 210 can also seal the through groove 203 after the moving plate 204 is pulled out of the cabinet 1, so that the staff can replace the metal plate on the moving plate 204, and prevent the high temperature inside the cabinet 1 from affecting the staff and the annealing of the other metal plates inside the cabinet 1.

[0028] The placement mechanism 3 includes a slide 301. Multiple slides 301 are opened on both sides of the front wall of the connecting frame 202 and extend into the interior of the cabinet 1. Slide plates 302 are slidably connected in the multiple slides 301. Grooves 304 are opened on the upper part of the adjacent side of the two slide plates 302. Through grooves 309 are opened on the lower part of the adjacent side of the two slide plates 302. The ends of multiple insert rods 209 away from the connecting plate 207 are all inserted into the grooves 304. Connecting strips 305 are slidably connected in the multiple slide plates 302. One end of multiple springs 307 is fixedly connected to the opposite side of the two connecting strips 305. The other end of multiple springs 307 is fixedly connected to the inner wall of the slide plate 302. Placement plates 308 are fixedly connected to the adjacent side of the two connecting strips 305.

[0029] The insert rod 209 slides within the groove 304, with its front part abutting against the inner front wall of the groove 304. When the moving plate 204 moves forward, the insert rod 209 drives the sliding plate 302 forward. When the annealed metal plate is completely removed from the cabinet 1, the sliding plate 302 is also completely pulled out of the slide groove 301. Because the placement plate 308 compresses the spring 307 when it is inside the sliding plate 302, and the sliding plate 302 abuts against the side wall of the cabinet 1, and because the rear part of the placement plate 308 is curved, the spring 307 pushes the placement plate 308 outward during the removal of the sliding plate 302. When the curved part of the placement plate 308 extends out of the slide groove 301, the placement plate 308 also... The plate gradually extends from the through groove 309, so that after the slide plate 302 is completely pulled out, the placement plate 308 can also be fully extended. At this time, the worker can let the annealed metal plate fall from the moving plate 204 onto the placement plate 308 for cooling or subsequent transfer. The moving plate 204 can then place a new metal plate and reset. During the reset process, the insert rod 209 will slide backward along the groove 304, so it will not affect the position of the slide plate 302. When the slide plate 302 needs to be reset, it is only necessary to push the slide plate 302 into the slide groove 301. When the arc surface at the rear of the placement plate 308 is squeezed, it will move into the slide plate 302 and compress the spring 307 until the placement plate 308 is completely retracted into the slide plate 302 and the slide plate 302 moves into the slide groove 301.

[0030] Multiple connecting bars 305 have multiple guide rods 306 running through their middle sections. Both ends of the multiple guide rods 306 are fixedly connected to the inner wall of the slide plate 302. Multiple springs 307 are sleeved on the outer periphery of the guide rods 306.

[0031] The guide rod 306 can limit the movement of the connecting bar 305 to ensure the stability of its movement. At the same time, the guide rod 306 can also limit the movement of the spring 307, thereby preventing the spring 307 from bending under pressure and affecting its normal use.

[0032] One end of a connecting rod 303 is fixedly connected to the front wall of one side of the slide plate 302, and the other end of multiple connecting rods 303 is fixedly connected to the front wall of the other side of the slide plate 302.

[0033] The connecting rod 303 can connect the corresponding slide plates 302 on both sides, so that the staff can push the connecting rod 303 to move the slide plates 302 on both sides at the same time.

[0034] The adjustment mechanism 4 includes a moving groove 401. Multiple moving grooves 401 are opened on the front side of the top wall of the moving plate 204. The rear ends of multiple moving grooves 401 extend through the inner front wall of the moving plate 204. The top of multiple moving grooves 401 is provided with evenly distributed slots 402. Fixed rods 404 are slidably connected to both sides inside the multiple moving grooves 401. Connecting rods 408 are slidably connected inside the multiple fixed rods 404. The top ends of multiple connecting rods 408 extend through the top wall of the fixed rods 404 and are fixedly connected to locking blocks 403. Multiple locking blocks 403 are engaged in the slots 402. The rear ends of multiple fixed rods 404 extend through the rear ends of the moving grooves 401 and are fixedly connected to support plates 405.

[0035] The operator can pull the locking block 403 out of the slot 402 and move the fixing rod 404 in the moving slot 401. When the fixing rod 404 moves, it can move the support plate 405. When the support plate 405 moves to the appropriate position, the locking block 403 can be locked into the slot 402 for limiting, thereby positioning the support plate 405. By moving the support plate 405 to different positions, it can be used to support metal plates of different specifications. At the same time, when the two support plates 405 are away from the bottom surface of the metal plate, the support limitation on the metal plate can be canceled, so that the metal plate can fall onto the corresponding lower placement plate 308.

[0036] Multiple connecting rods 408 are fixedly connected to the bottom end of a limiting plate 407, and multiple limiting plates 407 are slidably connected to the inner wall of the fixed rod 404.

[0037] By setting a limit plate 407, the connecting rod 408 and the locking block 403 can be limited. Therefore, when the operator pulls the locking block 403 upward, the connecting rod 408 can drive the locking block 403 to move upward, thereby preventing the operator from completely pulling out the locking block 403 and the connecting rod 408, which would affect the normal use of the mechanism.

[0038] Each of the multiple movable plates 204 has a limiting groove 406 on its inner rear wall, and the rear ends of the multiple support plates 405 are slidably connected to the inner wall of the limiting groove 406.

[0039] The movable plate 204 can be supported by the limiting groove 406, thereby ensuring the stability of the movement of the movable plate 204.

[0040] In this continuous annealing equipment for composite metal sheets, when different metals need to be annealed simultaneously, the metal sheets can be placed on the support plate 405 in the moving plate 204 and pushed into the cabinet 1. Then, the operator can control the annealing equipment via the control panel 214. Since different metals require different annealing times, after some metal sheets have been annealed, the corresponding servo motor 205 can be controlled to drive the bidirectional screw 206 at the output end to rotate. When the bidirectional screw 206 rotates, it can simultaneously move the connecting plates 207 on both sides closer or further away. When the connecting plate 207 moves, it can drive the insert rod 209 to move accordingly. When the insert rods 209 on both sides extend, they will be inserted into the connecting frame 202. At this time, the hydraulic cylinder 201 can drive the connecting frame 202 fixed at the output end to move. When the connecting frame 202 moves forward, it can drive the corresponding connected moving plate 204 to move forward through the insert rod 209. This allows the moving plate 204 and the metal plate placed in the moving plate 204 to be removed from the cabinet 1 and replaced, so as to achieve the effect of annealing different metal plates at the same time according to different needs. The insert rod 209 slides within the groove 304. Therefore, when the moving plate 204 moves forward, the insert rod 209 will drive the slide plate 302 to move forward as well. When the annealed metal plate is completely removed from the cabinet 1, the slide plate 302 will also be completely pulled out of the slide groove 301. During the removal of the slide plate 302, the spring 307 will push the placement plate 308 to extend outward. Therefore, after the slide plate 302 is completely pulled out, the placement plate 308 will also be fully extended. At this time, the operator can pull the locking block 403 out of the locking groove 402 and drive the fixing rod 404 to move within the moving groove 401. When the fixing rod 404 moves, it can drive the support plate 405 to move. When the two support plates 405 are away from the bottom surface of the metal plate, the support limit on the metal plate can be released. At this time, the metal plate will fall onto the corresponding lower placement plate 308 for cooling or for easy transfer by the operator.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
