Technical Field
[0001] This utility model relates to the field of flue gas duct wall forming technology, specifically a flue gas duct wall forming device with replaceable pressure plate. Background Technology
[0002] Flue gas ducts are an important component of environmental protection equipment such as dust collectors. Their pipe walls are usually made of metal sheets that are formed by pressing and welding. Taking large bag dust collectors as an example, their flue gas ducts are mostly large square tube structures. During production, the four pipe walls need to be pressed separately and then welded into a complete pipe. Most existing flue gas duct forming devices are designed for ducts of specific specifications or shapes. Their forming components (such as pressure plates) are fixedly connected to the equipment body or are an integral structure, making it difficult to flexibly replace them according to the shape requirements of different ducts. In the actual production of large flue gas ducts, different ducts often have different cross-sectional shapes and size requirements. Since the pressure plates of existing forming devices cannot be quickly replaced, when it is necessary to produce pipe walls of different shapes, multiple sets of different forming equipment are often required, resulting in high equipment investment costs, long production preparation cycles, low production efficiency, and multiple sets of equipment occupying a large amount of factory space. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a flue gas duct wall forming device with replaceable pressure plates. This solves the technical problem that existing devices require multiple forming units when forming flue gas duct walls of different specifications and shapes, resulting in high equipment investment costs. This addresses the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a flue gas duct wall forming device with replaceable pressure plate, comprising a U-shaped assembly frame embedded in the ground and a frame fixedly installed above the U-shaped assembly frame, wherein a movable seat is slidably connected in the U-shaped assembly frame along its width direction, and a pair of lifting seats capable of vertical lifting and lowering are provided at the top of the movable seat, a lower pressure plate is detachably installed at the top of the lifting seat, and a through hole corresponding to the lower pressure plate is opened at the top of the frame, and a pair of limiting components for limiting the position of the lower pressure plate are fixedly installed in the frame; A forming cylinder is fixedly installed at the top of the frame. The telescopic end of the forming cylinder passes through the top wall of the frame and is connected to a transmission seat. An upper pressure plate corresponding to the lower pressure plate is detachably installed at the bottom of the transmission seat.
[0005] Preferably, the limiting component includes a limiting cylinder horizontally mounted on the frame and located at one end of the through hole, a pair of limiting holes are provided at both ends of the lifting seat, a limiting sleeve is fixedly installed on the frame, a horizontal sliding block that is slidably connected to the telescopic end of the limiting cylinder is fixedly connected to the limiting sleeve, and a limiting plug that is inserted into the limiting hole is fixedly installed at one end of the horizontal sliding block.
[0006] Preferably, positioning rods are fixedly installed at the four corners of the top of the lifting seat, the bottom end of the lower pressure plate is inserted into the positioning rods, and the four corners of the lower pressure plate are connected to the top of the lifting seat by long screws.
[0007] Preferably, a pair of T-shaped slide rails are fixedly installed at the bottom of the transmission seat, the top of the upper pressure plate is slidably connected to the T-shaped slide rails, and a pair of connecting brackets that are inserted into the front end of the upper pressure plate are installed at the front end of the transmission seat. The top end of the connecting brackets is connected to the top end of the transmission seat by mounting screws.
[0008] Preferably, a lead screw module for driving the movable seat to slide is fixedly installed inside the U-shaped assembly frame, and guide rails for increasing the sliding stability of the movable seat are provided on both sides of the lead screw module.
[0009] Preferably, the top and front sides of the U-shaped assembly frame are rotatably connected with metal movable cover plates to ensure that operators can move back and forth.
[0010] Preferably, a pair of limiting slides are fixedly installed at both ends of the lifting seat, and a pair of movable slides are slidably connected to the inner walls of both ends of the U-shaped assembly frame. Each pair of movable slides has a vertically opened limiting slide groove corresponding to the pair of limiting slides on its inner side.
[0011] Preferably, the top of the movable seat is fixedly equipped with multiple multi-stage cylinders for driving a pair of lifting seats to move vertically.
[0012] This utility model provides a flue gas duct wall forming device with replaceable pressure plate, which has the following advantages: 1. The movable seat of this utility model is driven by a screw module to slide along the width of the U-shaped assembly frame. It is driven by a multi-stage cylinder of the lifting seat to achieve vertical lifting, so that the required lower pressure plate can be moved to the frame and the top of the lower pressure plate can extend out from the through hole. The limiting component drives the horizontal sliding block through the limiting cylinder, so that the limiting block is accurately inserted into the limiting hole of the lifting seat, ensuring that the lower pressure plate is accurately positioned and runs stably during the pressing process, thereby completing the automatic switching operation of the lower pressure plate. The metal movable cover plate at the top of the U-shaped assembly frame facilitates the movement of operators. At the same time, the metal movable cover plate can be lifted to replace the other idle lower pressure plate. The overall structure is flexible in use. At the same time, the lower pressure plate and other components are buried at the bottom, the overall footprint is small and will not interfere with other processes. 2. The lower pressure plate is connected to the lifting seat via a positioning rod and long screws, while the upper pressure plate is connected to the transmission seat via a T-shaped slide rail and connecting frame. Disassembly and installation are convenient. When it is necessary to produce flue gas pipe walls with different cross-sectional shapes or size requirements, there is no need to prepare multiple independent forming equipment. Only the corresponding upper pressure plate needs to be replaced, and the lower pressure plate in the U-shaped assembly frame is automatically replaced. This shortens the production preparation cycle and effectively solves the technical problems of the existing forming device's pressure plate being unreplaceable and having poor versatility.

[0015] 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.
[0016] Please see Figures 1-5This utility model provides a technical solution: a flue gas duct wall forming device with replaceable pressure plate, including a U-shaped assembly frame 1 embedded in the ground and a frame 2 fixedly installed above the U-shaped assembly frame 1. A movable seat 3 is slidably connected in the width direction inside the U-shaped assembly frame 1. A pair of lifting seats 4 that can move vertically are provided at the top of the movable seat 3. The movable seat 3 can drive the pair of lifting seats 4 and the lower pressure plate 5 installed at the top of the lifting seats 4 to move simultaneously. The lower pressure plate 5 is detachably installed at the top of the lifting seats 4. A through hole 6 corresponding to the lower pressure plate 5 is opened at the top of the frame 2. A pair of limiting components for limiting the position of the lower pressure plate 5 are fixedly installed in the frame 2. The lifting plate can move vertically and insert the lower pressure plate 5 into the through hole 6. The limiting components can limit and fix the lifting plate after it is fully raised. A forming cylinder 7 is fixedly installed at the top of the frame 2. The telescopic end of the forming cylinder 7 passes through the top wall of the frame 2 and is connected to a transmission seat 8. An upper pressure plate 9 corresponding to the lower pressure plate 5 is detachably installed at the bottom of the transmission seat 8. The forming cylinder 7 can drive the upper pressure plate 9 to descend through the transmission seat 8. In conjunction with the lower pressure plate 5, the forming operation of the flue gas duct wall can be completed.
[0017] As an embodiment of this utility model, the limiting component includes a limiting cylinder 10 horizontally mounted on the frame 2 and located at one end of the through hole 6. A pair of limiting holes 11 are provided at both ends of the lifting seat 4. A limiting sleeve 12 is fixedly installed on the frame 2. A horizontal sliding block 13 that is slidably connected to the telescopic end of the limiting cylinder 10 is fixedly connected to the limiting sleeve 12. A limiting plug 14 that is inserted into the limiting hole 11 is fixedly installed at one end of the horizontal sliding block 13. After the lifting seat 4 drives the lower pressure plate 5 to be fully inserted into the through hole 6, the limiting cylinder 10 runs and can drive the limiting plug 14 to be inserted into the limiting hole 11 through the horizontal sliding block 13. The limiting sleeve 12 is used to limit the position of the horizontal sliding block 13 and provide it with vertical support. After the above limiting insertion operation is completed, the lower pressure plate 5 is completely fixed on the frame 2 to facilitate the subsequent pressing operation.
[0018] As an embodiment of this utility model, positioning rods 15 are fixedly installed at the four corners of the top of the lifting seat 4 to prevent the lower pressure plate 5 from shifting after being placed on the top of the lifting seat 4. The bottom end of the lower pressure plate 5 is inserted into the positioning rods 15, and the four corners of the lower pressure plate 5 are connected to the top of the lifting seat 4 by long screws 16. After the above insertion operation is completed, the lower pressure plate 5 can be assembled by long screws 16.
[0019] As an embodiment of this utility model, a pair of T-shaped slide rails 17 are fixedly installed at the bottom of the transmission seat 8. The top of the upper pressure plate 9 is slidably connected to the T-shaped slide rails 17. A pair of connecting brackets 18 that are inserted into the front end of the upper pressure plate 9 are installed at the front end of the transmission seat 8. The top end of the connecting brackets 18 is connected to the top end of the transmission seat 8 by mounting screws 19. When it is necessary to replace the corresponding upper pressure plate 9, the mounting screws 19 can be separated from the transmission seat 8, and then the upper pressure plate 9 can be removed along the T-shaped slide rails 17, thereby completing the replacement of the upper pressure plate 9.
[0020] As an embodiment of this utility model, a lead screw module 20 for driving the movable seat 3 to slide is fixedly installed inside the U-shaped assembly frame 1. Guide rails 21 are provided on both sides of the lead screw module 20 to increase the sliding stability of the movable seat 3. The lead screw module 20, together with the guide rails 21, can drive the movable seat 3 to move inside the U-shaped assembly frame 1. The two lower pressure plates 5 at the top of the movable seat 3 are two lower pressure plates 5 of different specifications. When it is necessary to switch the lower pressure plates 5, the lead screw module 20 can drive the corresponding lower pressure plate 5 to move below the frame 2. Then the corresponding lower pressure plate 5 can be raised and fixed on the frame 2 by the limiting component, while the other lower pressure plate 5 will move below the metal movable cover plate 22.
[0021] As an embodiment of this utility model, the top front and rear sides of the U-shaped assembly frame 1 are rotatably connected with metal movable cover plates 22 to ensure that the operator can walk back and forth. The operator can walk on the metal movable cover plates 22 in the closed state, and can lift the corresponding metal movable cover plates 22 to quickly replace another idle lower pressure plate 5. The lower pressure plate 5 that is replaced can be used as a switching alternative to increase the flexibility of the device.
[0022] As an embodiment of this utility model, a pair of limiting slides 23 are fixedly installed at both ends of the lifting seat 4, and a pair of movable slide plates 24 are slidably connected to the inner walls of both ends of the U-shaped assembly frame 1. Each pair of movable slide plates 24 has a vertically opened limiting groove 25 corresponding to the pair of limiting slides 23 on its inner side. Since the movable slides are slidably connected to the movable slide plates 24 through the limiting groove 25, when the screw module 20 runs and drives the lifting seat 4 and the limiting slides 23 to move, it will drive the movable slide plates 24 to move synchronously. The limiting groove 25 on the inner side of the limiting slide plate, together with the movable slides, can increase the stability of the lifting seat 4 in the vertical direction.
[0023] As an embodiment of this utility model, a plurality of multi-stage cylinders 26 are fixedly installed at the top of the movable seat 3 to drive a pair of lifting seats 4 to move vertically. The multi-stage cylinders 26 can drive the lifting seats 4 and the lower pressure plate 5 located at the top of the lifting seats 4 to rise, so as to complete the switching operation of the lower pressure plate 5.
[0024] Those skilled in the art can connect all electrical components in this case to their compatible power supplies via wires, and appropriate controllers should be selected according to the actual situation to meet control requirements. The specific connection and control sequence are well-known technologies and will not be described in detail here.
[0025] The working principle and usage process of this utility model are as follows: After the device is started, the screw module 20 in the U-shaped assembly frame 1 operates according to the control command, driving the moving seat 3 to slide along the width direction of the U-shaped assembly frame 1. The top of the moving seat 3 is equipped with a pair of lifting seats 4 and a lower pressure plate 5 of different specifications. The screw module 20 accurately delivers the target lower pressure plate 5 to the bottom of the frame 2 (that is, the bottom of the through hole 6). The other lower pressure plate 5 stays under the metal movable cover plate 22 and waits for the next action. The guide rail 21 ensures that the moving seat 3 slides smoothly and is accurately positioned. After the target lower pressure plate 5 is in place, the multi-stage cylinder 26 at the top of the movable seat 3 is activated, pushing the lifting seat 4 to rise vertically along the limiting slide groove 25. The limiting slides 23 on both sides of the lifting seat 4 cooperate with the limiting slide groove 25 on the movable slide plate 24 to ensure vertical stability during the rising process. The lifting seat 4 drives the lower pressure plate 5 to pass through the through hole 6 on the frame 2, so that the top of the lower pressure plate 5 extends to the working position above the frame 2. After the lower pressure plate 5 is fully lifted into place, a pair of limit cylinders 10 inside the frame 2 act simultaneously, pushing the horizontal sliding block 13 to slide inside the limit sleeve 12, causing the limit insert 14 to be precisely inserted into the limit holes 11 at both ends of the lifting seat 4. The limit sleeve 12 provides vertical support for the horizontal sliding block 13, ensuring that the limit insert 14 is firmly inserted into the limit hole 11. At this time, the lower pressure plate 5 is rigidly locked on the frame 2, providing a stable and accurate positioning foundation for subsequent pressing. At the bottom of the transmission seat 8 at the top of the frame 2, the operator pushes the upper pressure plate 9 of the corresponding specification along a pair of T-shaped slide rails 17, so that the top of the upper pressure plate 9 slides with the T-shaped slide rails 17. Then, the connecting bracket 18 at the front end of the upper pressure plate 9 is inserted into the corresponding position at the front end of the transmission seat 8, and the assembly screw 19 is tightened from the top of the transmission seat 8 to fix the connecting bracket 18 to the transmission seat 8, thus completing the reliable assembly of the upper pressure plate 9. When it is necessary to produce flue gas pipe walls with different cross-sectional shapes or size requirements, the operator only needs to unscrew the mounting screws 19 to separate the connecting bracket 18 from the transmission seat 8, then pull out the old upper pressure plate 9 along the T-shaped slide rail 17, and then install the new upper pressure plate 9 that matches the lower pressure plate 5 according to the above steps. The whole process does not require disassembling the entire set of equipment, and the replacement is convenient and quick. After the upper pressure plate 9 and the lower pressure plate 5 are in place, the forming cylinder 7 is activated, and its telescopic end extends downward, pushing the transmission seat 8 and the upper pressure plate 9 vertically downward. The upper pressure plate 9 and the lower pressure plate 5, which is locked below, work together to apply a set pressure to the metal sheet placed between them, completing the forming of the flue gas pipe wall. After the forming operation is completed, the forming cylinder 7 retracts, driving the upper pressure plate 9 to rise and reset to the initial position. The formed pipe wall sheet can be taken out by the operator and enter the next welding process. When it is necessary to replace the idle lower pressure plate 5 in the U-shaped assembly frame 1 (i.e., the lower pressure plate 5 that is not currently in the working position and is located below the metal movable cover plate 22), the operator first lifts the metal movable cover plate 22 at the corresponding position upwards to expose the idle lower pressure plate 5 inside the U-shaped assembly frame 1 below. The operator can easily reach the lower pressure plate 5, unscrew the long screws 16 at its four corners to disengage it from the positioning rod 15 at the top of the lifting seat 4, and then remove the old lower pressure plate 5. Then, insert and position the new lower pressure plate 5 of another specification through the positioning rod 15, and tighten the long screws 16 to complete the assembly. After the replacement is completed, lower the metal movable cover plate 22, and the operator can walk normally on the cover plate without affecting other processes. When the production task needs to switch to another pipe wall specification, the system first controls the currently locked limit cylinder 10 to retract, so that the limit block 14 disengages from the limit hole 11. Then, it controls the multi-stage cylinder 26 to descend, so that the current lower pressure plate 5 falls back into the U-shaped assembly frame 1. Subsequently, the screw module 20 runs again, moving the replaced alternative lower pressure plate 5 (or the original lower pressure plate of another specification) to directly below the frame 2. By repeating the above lifting and limit locking operations, the automatic switching and calling of the lower pressure plate 5 can be completed, and a new round of forming operation can be quickly started.
[0026] 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.
