Technical Field

[0001] The present application relates to the technical field of corrugated plate welding, and in particular to a pressing device and method for corrugated plate welding. Background Art

[0002] Liquefied natural gas (LNG) cryogenic storage devices usually adopt a corrugated plate structure to achieve effective heat insulation and support for cryogenic media. During the manufacturing process of cryogenic storage devices, the corrugated plates need to be connected by lap welding. However, since corrugated plates are usually in a thin plate structure, during the welding process, the overlapping parts are likely to warp due to uneven heat input or welding expansion deformation, thereby causing problems such as unstable weld quality, insufficient structural connection strength, and product deformation, seriously affecting the sealing performance and safety of LNG storage tanks. Summary of the Invention

[0003] In order to improve the defect that during the welding process of corrugated plates, the overlapping parts are likely to warp due to uneven heat input or welding expansion deformation, thereby causing problems such as unstable weld quality, insufficient structural connection strength, and product deformation, the present application provides a pressing device and method for corrugated plate welding.

[0004] The pressing device and method for corrugated plate welding provided by the present application adopt the following technical solutions: A pressing device for corrugated plate welding includes a first clamping mechanism, a second clamping mechanism arranged in alignment with the first clamping mechanism, a pressing and supporting mechanism located between the first clamping mechanism and the second clamping mechanism and connected to the first clamping mechanism and the second clamping mechanism at both ends respectively, a connecting support rod threadedly connected to the pressing and supporting mechanism and arranged in the vertical direction, a corrugated plate pressing mechanism connected to the lower end of the connecting support rod, and a temperature regulating mechanism connected to the corrugated plate pressing mechanism and used for tightly attaching to the surface of the corrugated plate; both the first clamping mechanism and the second clamping mechanism are used for clamping the peak nodes of the corrugated plate. The temperature regulating mechanism includes a heat-conducting top pressing plate assembly connected to the corrugated plate pressing mechanism, a temperature detection assembly connected to the bottom of the heat-conducting top pressing plate assembly, a heat-conducting tube assembly inserted into the heat-conducting top pressing plate assembly, a coolant storage tank fixedly connected to the pressing and supporting mechanism and communicated with the heat-conducting tube assembly, a coolant circulation pump arranged at the bottom side of the coolant storage tank and connected to the heat-conducting tube assembly, and a heat dissipation assembly connected to the side wall of the coolant storage tank; the temperature detection assembly is electrically connected to the coolant circulation pump and the heat dissipation assembly respectively.

[0005] By adopting the above technical solution, the first clamping mechanism and the second clamping mechanism are aligned and respectively clamp the adjacent wave crest nodes of the corrugated plate to provide overall support. Subsequently, by rotating the connecting support rod threadedly connected to the pressing and supporting mechanism, the connecting support rod moves downward in the vertical direction, thereby driving the corrugated plate pressing mechanism connected to the lower end and the heat conduction top pressing plate assembly connected to the corrugated plate pressing mechanism to move downward as a whole, and then pressing the heat conduction top pressing plate assembly against the side surface of the weld in the area to be welded of the corrugated plate, realizing the pressing operation on the side of the weld; During the welding process, the temperature detection component real-time monitors the temperature state of the contact area between the heat conduction top pressing plate assembly and the corrugated plate. When the temperature reaches the preset upper limit, the temperature detection component triggers the start of the coolant circulation pump and the heat dissipation component through electrical connection. The coolant circulation pump pumps the coolant from the coolant storage tank to the inside of the heat conduction top pressing plate assembly via the heat conduction pipe assembly for cooling treatment. At the same time, the heat dissipation component arranged on the side wall of the coolant storage tank assists in accelerating the heat dissipation and cooling process. When it is detected that the temperature drops to the preset lower limit, the temperature detection component triggers the coolant circulation pump and the heat dissipation component to stop again, thus forming a temperature control closed loop. Through the structural linkage and thermal control coordination method of the present application, not only can the position of the corrugated plate be stabilized during the welding process and the warping of the plate caused by welding stress be prevented, but also the risk of local deformation caused by heat input can be reduced by active temperature control, thereby significantly improving the forming quality, welding consistency and product structure stability of the corrugated plate lap welding.

[0006] Preferably, the heat dissipation component includes heat dissipation fins connected to the side wall of the coolant storage tank and arranged along the length direction of the coolant storage tank, and a heat dissipation fan connected to the side wall of the coolant storage tank and located at the end of the heat dissipation fins; the heat dissipation fan is electrically connected to the temperature detection component, and a plurality of the heat dissipation fins are arranged in an array along the width direction of the coolant storage tank.

[0007] By adopting the above technical solution, when the temperature detection component detects that the temperature of the corrugated plate weld area reaches the preset upper limit value, the temperature detection component triggers the start of the cooling fan. The cooling fan generates an air flow that blows along the side wall direction of the coolant storage tank to enhance the heat exchange efficiency between the air and the tank body. At the same time, a plurality of heat dissipation fins arranged along the side wall of the coolant storage tank and in its length direction come into large-area contact with the external air under the impact of the air flow. Through the heat conduction of the heat dissipation fins and the function of expanding the heat exchange area, the heat dissipation process of the coolant inside the tank body is accelerated. The plurality of heat dissipation fins are arranged in an array along the width direction of the coolant storage tank, which helps to evenly cover the entire coolant cavity area and increase the distribution density of the heat conduction path, thereby achieving a more efficient cooling effect. The structure of the present application realizes dynamic start-stop control through the electrical connection between the temperature detection component and the cooling fan, and forms a forced convection cooling mechanism with rapid response in combination with the densely arranged heat dissipation fins, which can effectively improve the initiative and accuracy of temperature adjustment of the corrugated plate pressing device during the welding process, thereby preventing structural deformation caused by local overheating and further ensuring the weld forming quality and the geometric stability of the overall corrugated plate.

[0009] By adopting the above technical solution, the first clamping mechanism and the second clamping mechanism provide an overall rigid support framework through the clamping support plate. The locking fixed plate is arranged at the end of the clamping support plate, making the clamping mechanism have a stable structural load-bearing foundation. The movable clamping component realizes the guiding and positioning of the adjustable position through the clamping sliding seat and is arranged opposite to the fixed clamping component to form a paired clamping surface. When the fixed locking component is rotated, the fixed locking component pushes the movable clamping component to move in a direction towards the fixed clamping component through a pressing action, so that the movable clamping component and the fixed clamping component gradually approach and finally clamp the corrugated plate peak node, realizing the efficient clamping and fixing of the corrugated plate. The present application realizes the guided movement of the movable clamping component through the clamping sliding seat, making the clamping process smoother. Combined with the quick release and reset operations of the fixed locking component, the clamping efficiency is effectively improved, the operation complexity is reduced, and at the same time, the clamping reliability and the repeated positioning accuracy are ensured, thereby significantly improving the corrugated plate positioning accuracy and structural stability during the welding operation.

[0010] Preferably, the locking fixing plate includes a horizontal fixing plate fixedly connected to the clamping support plate, and a vertical locking plate connected to the horizontal fixing plate and vertically arranged; The fixed locking assembly includes a locking guide base fixedly connected to the vertical locking plate, a swing transmission part with one end hinged to the locking guide base, a handle hinge part hinged to the other end of the swing transmission part, a locking handle fixedly connected to the handle hinge part and arranged at an angle, and a pressing locking rod movably inserted into the locking guide base and hinged to the end of the handle hinge part at one end. The swing transmission part is hinged at the connection positions of the handle hinge part, the locking handle.

[0011] By adopting the above technical solutions, the locking fixing plate and the vertically arranged vertical locking plate together form an "L"-shaped stable support frame through the horizontal fixing plate arranged on one side of the clamping support plate, which is used to install and guide the working actions of the fixed locking assembly; the locking guide base is fixedly arranged on the surface of the vertical locking plate to provide a rotation fulcrum and a guiding channel. The pressing locking rod is movably inserted into the locking guide base, and the upper end of the pressing locking rod is hinged to the handle hinge part; When the locking handle is rotated, due to the angular arrangement between the locking handle and the handle hinge part, the handle hinge part will be driven to rotate around the hinge point between the handle hinge part and the swing transmission part, further pushing the other end of the swing transmission part to swing around the hinge point between the locking guide base and the swing transmission part. The handle hinge part rotates around the hinge point with the pressing locking rod, driving the pressing locking rod to move outwards along the guiding direction to realize the pressing and pushing operation on the movable clamping assembly. Through the lever amplification and transmission design of the link mechanism, only a small manual torque needs to be applied to obtain a large clamping force, effectively improving the clamping efficiency and clamping stability. Moreover, the structure of this application has good self-locking ability and operation flexibility, can realize quick clamping and release, and improves the operation convenience and use reliability of the corrugated plate welding tooling under complex working conditions.

[0012] Preferably, a clamping sliding groove is arranged between the clamping support plate and the locking fixing plate along the length direction of the clamping support plate, and the two clamping sliding grooves are symmetrically arranged on both sides of the clamping support plate; the two clamping sliding seats are respectively connected to both sides of the movable clamping assembly and movably inserted into the two clamping sliding grooves; The clamping sliding seat includes an inclined surface limiting convex edge for movably inserting into the clamping sliding groove, and a fixed connection convex edge inserted between the clamping support plate and the movable clamping assembly and detachably connected to the upper side of the movable clamping assembly. A sliding seat guiding groove is arranged between the inclined surface limiting convex edge and the fixed connection convex edge, and an inclined surface guiding convex edge inserted into the sliding seat guiding groove is arranged on the lower side of the clamping sliding groove.

[0013] By adopting the above technical solution, the clamping sliding grooves are symmetrically arranged on both sides of the clamping support plate to guide the horizontal movement of the movable clamping assembly. The two clamping sliding seats are respectively inserted into the corresponding clamping sliding grooves in a movable manner, thus forming a guide pair relationship that can slide along the clamping direction. The inclined surface limiting convex edge of the clamping sliding seat is embedded in the clamping sliding groove to achieve insertion and limitation, and the fixed connection convex edge is fixed to the upper side of the movable clamping assembly through a detachable connection method, thereby realizing the flexible installation and replacement of the movable clamping assembly. The sliding seat guiding groove provided between the inclined surface limiting convex edge and the fixed connection convex edge provides a stable sliding path, and an inclined surface guiding convex edge inserted into the guiding groove is provided on the lower side of the clamping sliding groove. Through the above insertion structure, a complete guiding and locking fit is formed to ensure that the clamping sliding seat will not break away or swing and shift during the sliding process. The structure of the present application realizes high-precision guiding and positioning of the movable clamping assembly, and improves the repeatability and modularity of the clamping operation through the form of two-way limitation and detachable connection, thereby making the corrugated plate clamping process more stable and reliable, and effectively improving the adaptability, precision retention and maintenance convenience of the welding fixture during the clamping process of plates with different sizes.

[0014] Preferably, the pressing support mechanism includes a support frame body with two ends respectively located on the upper sides of the first clamping mechanism and the second clamping mechanism, and a fixed screw component inserted into the end of the support frame body; the two fixed screw components are inserted into both ends of the support frame body and are respectively in threaded cooperation with the first clamping mechanism and the second clamping mechanism.

[0015] By adopting the above technical solution, the support frame body is used to provide overall structural rigidity and connection base. Fixed screw components are provided at both ends of the support frame body. The fixed screw components are installed in the support frame body by insertion and are respectively in threaded cooperation with the upper structures of the first clamping mechanism and the second clamping mechanism, improving the alignment accuracy and pressing balance of the pressing fixture in the welding process, thereby further enhancing the welding quality and structural stability.

[0016] Preferably, adjusting strip holes are provided on the support frame body along the length direction of the support frame body and are located at both ends of the support frame body, and a pressing adjustment hole is provided between the two adjusting strip holes; The pressing support mechanism further includes a fixed nut component provided at the upper opening end of the pressing adjustment hole. The connecting support rod is inserted into the fixed nut component and the pressing adjustment hole and is in threaded cooperation with the fixed nut component. The fixed screw component is inserted into the adjusting strip hole and is used to move along the length direction of the adjusting strip hole to adjust the distance between the first clamping mechanism and the second clamping mechanism.

[0017] By adopting the above technical solution, the adjusting strip-shaped hole is used to provide an installation channel for the fixed screw assembly to slide along the strip-shaped hole, so as to realize the adjustment of the distance between the first clamping mechanism and the second clamping mechanism, and further adapt to the pressing requirements of corrugated plates of different sizes; the connecting support rod is inserted through the pressing adjustment hole and is in threaded cooperation with the fixed nut assembly. By rotating the connecting support rod, the connecting support rod moves up and down in the vertical direction, and then drives the corrugated plate pressing mechanism below to apply or release pressure to the corrugated plate. At the same time, the sliding operation of the fixed screw assembly along the adjusting strip-shaped hole can cooperate with the overall position of the corrugated plate pressing mechanism for pre-alignment and clamping position adjustment. The structure of this application constructs a multi-dimensional adjustment mechanism of "horizontal fine-tuning + vertical pressing" through the cooperation of the thread pair and the strip-shaped hole, which not only improves the accuracy and stability of the pressing action, but also enhances the adaptability range and on-site operation flexibility of the pressing tooling, thus effectively ensuring the alignment accuracy and pressing reliability of the corrugated plate during the welding process, improving the welding quality and reducing the need for human intervention.

The fixed screw body passes through the clamping and fixing component and the adjusting strip-shaped hole, and the end is in threaded cooperation with the clamping support plate.

[0019] By adopting the above technical solution, the clamping support plate is used to provide the bearing basis for the clamping structure; the clamping and fixing component covers above the adjusting strip-shaped hole through the positioning and installation method. The upper end of the fixed screw body is in threaded cooperation with the clamping and fixing component, and the lower end passes through the clamping and fixing component and the adjusting strip-shaped hole and then is threadedly connected to the clamping support plate. By rotating the fixed screw body, the clamping and fixing component and the clamping support plate can be driven to approach each other to clamp the upper and lower sides of the support frame body. Through the two-way threaded cooperation between the clamping and fixing component and the clamping support plate, a stable and adjustable connection method between the support frame body and the clamping mechanism is realized, which not only improves the adaptability of the device to corrugated plates of different widths, but also ensures the connection strength and repeated positioning accuracy of the clamping structure under high-load conditions, thus providing higher stability and operation accuracy for the subsequent pressing and welding processes.

[0020] Preferably, the corrugated plate pressing mechanism includes a pressing plate body connected to the connecting support rod, a rotating bearing arranged between the connecting support rod and the pressing plate body and respectively connected to the connecting support rod and the pressing plate body, and a vibration component fixedly connected to the upper side of the pressing plate body.

[0021] By adopting the above technical solutions, the corrugated plate pressing mechanism is used to achieve vertical pressing and dynamic fitting of the welded joint area of the corrugated plate; the rotating bearings are respectively connected to the connecting support rod and the pressing plate body, and are used to provide a certain rotational compensation ability during the pressing process, enabling the pressing plate body to move up and down in the vertical direction, avoiding the deviation of the pressing surface or uneven force caused by the small displacement of the connecting support rod or the uneven surface of the corrugated plate, and at the same time improving the flexibility and stability of the pressing action; a vibration component is fixedly connected to the upper side of the pressing plate body, and the vibration component can apply vibrations with a small frequency to the pressing plate body during the pressing process, which helps to disperse the stress concentration caused by welding thermal deformation and promotes a closer fit between the corrugated plate and the pressing surface, thereby improving the uniformity and stability of the pressing effect. At the same time, it also helps the welding heat to spread to the surrounding area and avoid thermal stress concentration. Through the combined method of "rotational compensation + vibration assistance", the present application further suppresses warping deformation, improves the consistency and reliability of weld formation, and effectively enhances the adaptability and welding quality of the entire welding tooling system on the basis of ensuring the stable output of the pressing force.

The coolant circulation pump causes the coolant to flow from the coolant storage tank into the heat conduction top pressing plate assembly through the heat conduction pipe assembly, achieving active cooling of the welding heat source area to suppress the warping of the corrugated plate caused by thermal expansion; when it is detected that T≤T 低 =T 预 -ΔT, the temperature detection component triggers the shutdown of the coolant circulation pump and the heat dissipation component, stopping the flow of the coolant to prevent energy consumption waste and reverse thermal stress impact caused by overcooling. Through the multi-step linkage operation of "clamping and positioning, vertical pressing, temperature control closed-loop, and dynamic cooling", this method constructs a precise and efficient corrugated plate welding assistance system, which can significantly improve the geometric stability of the weld and the controllability of the thermal field, enhancing the forming consistency and structural quality reliability of the welding process.

During the welding process, the temperature detection component monitors the temperature state of the contact area between the heat-conducting top pressing plate component and the corrugated plate in real time. When the temperature reaches the preset upper limit, the temperature detection component triggers the start of the coolant circulation pump and the heat dissipation component through electrical connection.

[0032] The following will further describe the present application in detail with reference to the attached Figures 1 to 6 drawings.

[0033] The embodiment of the present application discloses a pressing device and method for corrugated plate welding. Referring to Figure 1 and Figure 2 , a pressing device for corrugated plate welding includes a first clamping mechanism 1, a second clamping mechanism 2 arranged in alignment with the first clamping mechanism 1, a pressing support mechanism 3 located between the first clamping mechanism 1 and the second clamping mechanism 2 and connected to the first clamping mechanism 1 and the second clamping mechanism 2 at both ends respectively, a connecting support rod 4 threadedly connected to the pressing support mechanism 3 and arranged in the vertical direction, a corrugated plate pressing mechanism 5 connected to the lower end of the connecting support rod 4, and a temperature adjustment mechanism 6 connected to the corrugated plate pressing mechanism 5 and used to closely adhere to the surface of the corrugated plate; both the first clamping mechanism 1 and the second clamping mechanism 2 are used to clamp the wave peak nodes of the corrugated plate; The temperature adjustment mechanism 6 includes a heat-conducting top pressing plate component 61 connected to the corrugated plate pressing mechanism 5, a temperature detection component 62 connected to the bottom of the heat-conducting top pressing plate component 61, a heat-conducting pipe component 63 inserted into the heat-conducting top pressing plate component 61, a coolant storage tank 64 fixedly connected to the pressing support mechanism 3 and communicated with the heat-conducting pipe component 63, a coolant circulation pump 65 arranged at the bottom side of the coolant storage tank 64 and connected to the heat-conducting pipe component 63, and a heat dissipation component 66 connected to the side wall of the coolant storage tank 64; the temperature detection component 62 is electrically connected to the coolant circulation pump 65 and the heat dissipation component 66 respectively.

[0034] In this application, the first clamping mechanism 1 and the second clamping mechanism 2 are aligned to respectively clamp the adjacent wave peak nodes of the corrugated plate to provide overall support. Subsequently, by rotating the connecting support rod 4 threadedly connected to the pressing and supporting mechanism 3, the connecting support rod 4 moves downward in the vertical direction, thereby driving the corrugated plate pressing mechanism 5 connected to the lower end and the heat conduction top pressing plate assembly 61 connected to the corrugated plate pressing mechanism 5 to move downward as a whole, and further pressing the heat conduction top pressing plate assembly 61 against the surface of the side of the weld in the area to be welded of the corrugated plate, so as to realize the pressing operation on the side of the weld; During the welding process, the temperature detection component 62 monitors the temperature state of the contact area between the heat conduction top pressing plate assembly 61 and the corrugated plate in real time. When the temperature reaches the preset upper limit, the temperature detection component 62 triggers the start of the coolant circulation pump 65 and the heat dissipation component 66 through electrical connection. The coolant circulation pump 65 pumps the coolant from the coolant storage tank 64 to the inside of the heat conduction top pressing plate assembly 61 through the heat conduction pipe assembly 63 for cooling treatment. At the same time, the heat dissipation component 66 arranged on the side wall of the coolant storage tank 64 assists in accelerating the heat dissipation and cooling process. When it is detected that the temperature drops to the preset lower limit, the temperature detection component 62 triggers the coolant circulation pump 65 and the heat dissipation component 66 to stop again, thereby forming a temperature control closed loop. Through the structural linkage and thermal control coordination method, this application can not only stabilize the position of the corrugated plate during the welding process and prevent the warping of the plate caused by welding stress, but also reduce the risk of local deformation caused by heat input through active temperature control, thereby significantly improving the forming quality, welding consistency and product structure stability of the corrugated plate lap welding.

[0035] Further, as Figure 2 shown, the heat dissipation component 66 includes heat dissipation fins 661 connected to the side wall of the coolant storage tank 64 and arranged along the length direction of the coolant storage tank 64, and a heat dissipation fan 662 connected to the side wall of the coolant storage tank 64 and located at the end of the heat dissipation fins 661; the heat dissipation fan 662 is electrically connected to the temperature detection component 62, and a plurality of heat dissipation fins 661 are arranged in an array along the width direction of the coolant storage tank 64.

[0036] When the temperature detection component 62 of the present application detects that the temperature of the corrugated plate weld area reaches the preset upper limit value, the temperature detection component 62 triggers the start of the cooling fan 662. The cooling fan 662 generates an air flow that blows along the side wall direction of the coolant storage tank 64 to enhance the heat exchange efficiency between the air and the box body. At the same time, a plurality of heat dissipation fins 661 arranged along the side wall of the coolant storage tank 64 and along its length direction come into large-area contact with the external air under the impact of the air flow. Through the heat conduction and extended heat exchange area effect of the heat dissipation fins 661, the heat dissipation process of the coolant inside the box body is accelerated. The plurality of heat dissipation fins 661 are arranged in an array along the width direction of the coolant storage tank 64, which helps to evenly cover the entire coolant cavity area and improve the distribution density of the heat conduction path, thereby achieving a more efficient cooling effect. The structure of the present application realizes dynamic start-stop control through the electrical connection between the temperature detection component 62 and the cooling fan 662, and forms a forced convection cooling mechanism with rapid response in combination with the densely arranged heat dissipation fins 661, which can effectively improve the initiative and accuracy of temperature adjustment of the corrugated plate pressing device during the welding process, thereby preventing structural deformation caused by local overheating and further ensuring the weld forming quality and the geometric stability of the overall corrugated plate; The temperature detection component 62 is preferably a temperature sensor.

[0037] Furthermore, as Figure 2 shown, both the first clamping mechanism 1 and the second clamping mechanism 2 include a clamping support plate 11, a locking fixing plate 12 connected to the end of the clamping support plate 11, a fixed locking component 13 connected to the locking fixing plate 12, a fixed clamping component 14 fixedly connected to the bottom of the clamping support plate 11, a clamping sliding seat 15 movably inserted between the clamping support plate 11 and the locking fixing plate 12, and a movable clamping component 16 detachably connected to the clamping sliding seat 15 and arranged corresponding to the fixed clamping component 14; the fixed locking component 13 is used to press and push the movable clamping component 16 to move in the direction close to the fixed clamping component 14.

[0038] In the present application, the first clamping mechanism 1 and the second clamping mechanism 2 provide an integral rigid support frame through the clamping support plate 11. The locking fixing plate 12 is arranged at the end of the clamping support plate 11, enabling the clamping mechanism to have a stable structural load-bearing foundation. The movable clamping assembly 16 realizes the guiding and positioning of adjustable position through the clamping sliding seat 15, and is arranged opposite to the fixed clamping assembly 14 to form a paired clamping surface. When the fixed locking assembly 13 is rotated, the fixed locking assembly 13 pushes the movable clamping assembly 16 to move in the direction towards the fixed clamping assembly 14 through a pressing action, causing the movable clamping assembly 16 and the fixed clamping assembly 14 to gradually approach and finally clamp the peak node of the corrugated plate, achieving efficient clamping and fixing of the corrugated plate. In the present application, the movable clamping assembly 16 is enabled to move in a guided manner through the clamping sliding seat 15, making the clamping process smoother. Combined with the fixed locking assembly 13, rapid release and reset operations can be performed, effectively improving the clamping efficiency, reducing the operation complexity, and at the same time ensuring the clamping reliability and repeated positioning accuracy, thereby significantly improving the positioning accuracy and structural stability of the corrugated plate during the welding operation; The fixed locking assembly 13 is preferably a push-pull type quick clamp.

[0039] Specifically, as Figure 3 shown, the locking fixing plate 12 includes a horizontal fixing plate 121 fixedly connected to the clamping support plate 11, and a vertical locking plate 122 connected to the horizontal fixing plate 121 and arranged vertically; The fixed locking assembly 13 includes a locking guide base 131 fixedly connected to the vertical locking plate 122, a swing transmission part 132 with one end hinged to the locking guide base 131, a handle hinge part 133 hinged to the other end of the swing transmission part 132, a locking handle 134 fixedly connected to the handle hinge part 133 and arranged at an angle, and a pressing locking rod 135 movably inserted into the locking guide base 131 with one end hinged to the end of the handle hinge part 133. The swing transmission part 132 is hinged at the connection positions with the handle hinge part 133 and the locking handle 134.

[0040] In the present application, the locking fixing plate 12 jointly constitutes an "L"-shaped stable support frame through the horizontal fixing plate 121 arranged on one side of the clamping support plate 11 and the vertically arranged vertical locking plate 122, for installing and guiding the working action of the fixed locking assembly 13; the locking guide base 131 is fixedly arranged on the surface of the vertical locking plate 122 to provide a rotation fulcrum and a guiding channel. The pressing locking rod 135 is movably inserted into the locking guide base 131, and the upper end of the pressing locking rod 135 is hinged and connected to the handle hinge part 133; When the rotary locking handle 134 is operated, since the locking handle 134 and the handle hinge part 133 are arranged at an angle, it will drive the handle hinge part 133 to rotate around the hinge point between the handle hinge part 133 and the swing transmission part 132, and further push the other end of the swing transmission part 132 to swing around the hinge point between the locking guide base 131 and the swing transmission part 132. The handle hinge part 133 rotates around the hinge point with the pressing locking rod 135, driving the pressing locking rod 135 to move outward along the guiding direction to realize the pressing and pushing operation on the movable clamping assembly 16. Through the lever amplification and transmission design of the link mechanism, only a small manual torque needs to be applied to obtain a large clamping force, effectively improving the clamping efficiency and clamping stability. Moreover, the structure of this application has good self-locking ability and operation flexibility, can realize quick clamping and releasing, and improves the operation convenience and use reliability of the corrugated plate welding tooling under complex working conditions; When the above three hinge points are on the same straight line, the fixed locking assembly 13 is in the locked state.

[0041] More specifically, as Figure 4 shown, a clamping sliding groove 17 is provided between the clamping support plate 11 and the locking fixing plate 12 and is arranged along the length direction of the clamping support plate 11. The two clamping sliding grooves 17 are symmetrically arranged on both sides of the clamping support plate 11; the two clamping sliding seats 15 are respectively connected to both sides of the movable clamping assembly 16 and are movably inserted into the two clamping sliding grooves 17; The clamping sliding seat 15 includes an inclined surface limiting convex edge 151 for movably inserting into the clamping sliding groove 17, and a fixed connection convex edge 152 inserted between the clamping support plate 11 and the movable clamping assembly 16 and detachably connected to the upper side of the movable clamping assembly 16. A sliding seat guiding groove 153 is provided between the inclined surface limiting convex edge 151 and the fixed connection convex edge 152, and an inclined surface guiding convex edge 171 inserted into the sliding seat guiding groove 153 is provided on the lower side of the clamping sliding groove 17.

[0042] In this application, the clamping sliding grooves 17 are symmetrically arranged on both sides of the clamping support plate 11 to guide the horizontal movement of the movable clamping assembly 16. The two clamping sliding seats 15 are respectively inserted into the corresponding clamping sliding grooves 17 in a movable manner, thus forming a guide pair relationship that can slide along the clamping direction. The inclined surface limit convex edge 151 of the clamping sliding seat 15 is embedded into the clamping sliding groove 17 to achieve insertion and limitation. The fixed connection convex edge 152 is fixedly connected to the upper side of the movable clamping assembly 16 through a detachable connection method, thereby realizing the flexible installation and replacement of the movable clamping assembly 16. The sliding seat guide groove 153 provided between the inclined surface limit convex edge 151 and the fixed connection convex edge 152 provides a stable sliding path. The lower side of the clamping sliding groove 17 is provided with an inclined surface guide convex edge 171 inserted into the sliding seat guide groove 153. Through the above insertion structure, a complete guiding and locking fit is formed to ensure that the clamping sliding seat 15 will not break away or swing and deviate during the sliding process. The structure of this application realizes the high-precision guiding and positioning of the movable clamping assembly 16, and improves the repeatability and modularity of the clamping operation through the form of two-way limitation and detachable connection, thereby making the corrugated plate clamping process more stable and reliable, and effectively improving the adaptability, accuracy retention and maintenance convenience of the welding fixture during the clamping process of plates with different sizes.

[0043] In addition, as Figure 5 shown, the pressing support mechanism 3 includes a support frame body 31 with two ends respectively connected to the upper sides of the first clamping mechanism 1 and the second clamping mechanism 2, and a fixed screw component 32 inserted into the end of the support frame body 31; the two fixed screw components 32 are inserted into both ends of the support frame body 31 and are respectively in threaded cooperation with the first clamping mechanism 1 and the second clamping mechanism 2.

[0044] In this application, the support frame body 31 is used to provide the overall structural rigidity and connection base. The two ends of the support frame body 31 are provided with fixed screw components 32. The fixed screw components 32 are installed in the support frame body 31 by insertion and are respectively in threaded cooperation with the upper structures of the first clamping mechanism 1 and the second clamping mechanism 2, improving the alignment accuracy and pressing balance of the pressing fixture in the welding process, thereby further enhancing the welding quality and structural stability.

[0045] Moreover, as Figure 2 and Figure 5 shown, the support frame body 31 is provided with adjusting strip holes 311 arranged along the length direction of the support frame body 31 and located at both ends of the support frame body 31, and pressing adjustment holes 312 arranged between the two adjusting strip holes 311; The pressing and supporting mechanism 3 further includes a fixing nut assembly 33 provided at the upper opening end of the pressing adjustment hole 312. The connecting support rod 4 is inserted into the fixing nut assembly 33 and the pressing adjustment hole 312 and is in threaded cooperation with the fixing nut assembly 33. The fixing screw assembly 32 is inserted into the adjustment strip hole 311 and is used to move along the length direction of the adjustment strip hole 311 to adjust the distance between the first clamping mechanism 1 and the second clamping mechanism 2.

[0046] The adjustment strip hole 311 of the present application is used to provide an installation channel for the fixing screw assembly 32 to slide along the strip hole, so as to realize the adjustment of the distance between the first clamping mechanism 1 and the second clamping mechanism 2, and further adapt to the pressing requirements of corrugated plates of different sizes; the connecting support rod 4 passes through the pressing adjustment hole 312 and is in threaded cooperation with the fixing nut assembly 33. By rotating the connecting support rod 4, the connecting support rod 4 moves up and down in the vertical direction, and then drives the lower corrugated plate pressing mechanism 5 to apply or release pressure to the corrugated plate. At the same time, the sliding operation of the fixing screw assembly 32 along the adjustment strip hole 311 can cooperate with the overall position of the corrugated plate pressing mechanism 5 for pre-alignment and clamping position adjustment. The structure of the present application constructs a multi-dimensional adjustment mechanism of "horizontal fine adjustment + vertical pressing" through the cooperation of the thread pair and the strip hole, which not only improves the accuracy and stability of the pressing action, but also enhances the adaptability range and on-site operation flexibility of the pressing tooling, thereby effectively ensuring the alignment accuracy and pressing reliability of the corrugated plate during the welding process, improving the welding quality and reducing the need for human intervention.

[0047] Further, as Figure 5 shown, both the first clamping mechanism 1 and the second clamping mechanism 2 include a clamping support plate 11; the fixing screw assembly 32 includes a clamping and fixing part 321 provided on the upper side of the adjustment strip hole 311, and a fixing screw body 322 inserted into the clamping and fixing part 321 and in threaded cooperation with the clamping and fixing part 321. The fixing screw body 322 passes through the clamping and fixing part 321 and the adjustment strip hole 311 and the end is in threaded cooperation with the clamping support plate 11.

[0048] The clamping support plate 11 of the present application is used to provide a bearing foundation for the clamping structure; the clamping and fixing component 321 is covered above the adjusting strip hole 311 through a positioning and installation method. The upper end of the fixing screw body 322 is in threaded cooperation with the clamping and fixing component 321, and the lower end passes through the clamping and fixing component 321 and the adjusting strip hole 311 and then is threadedly connected to the clamping support plate 11. By rotating the fixing screw body 322, the clamping and fixing component 321 and the clamping support plate 11 can be driven to approach each other to clamp the upper and lower side surfaces of the support frame body 31. Through the bidirectional threaded cooperation between the clamping and fixing component 321 and the clamping support plate 11, a stable and adjustable connection method between the support frame body 31 and the clamping mechanism is realized. This not only improves the adaptability of the device to corrugated plates of different widths, but also ensures the connection strength and repeated positioning accuracy of the clamping structure under high-load conditions, thereby providing higher stability and operation accuracy for the subsequent pressing and welding processes; The clamping and fixing component 321 is preferably a nut.

[0049] Furthermore, as Figure 5 shown, the corrugated plate pressing mechanism 5 includes a pressing plate body 51 connected to the connecting support rod 4, a rotating bearing 52 provided between the connecting support rod 4 and the pressing plate body 51 and connected to the connecting support rod 4 and the pressing plate body 51 respectively, and a vibration component 53 fixedly connected to the upper side surface of the pressing plate body 51.

[0050] The corrugated plate pressing mechanism 5 of the present application is used to realize the vertical pressing and dynamic fitting of the welded joint area of the corrugated plate; the rotating bearing 52 is connected to the connecting support rod 4 and the pressing plate body 51 respectively, and is used to provide a certain rotational compensation ability during the pressing process, so that the pressing plate body 51 moves up and down in the vertical direction, avoiding the deviation of the pressing surface or uneven force caused by the small displacement of the connecting support rod 4 or the uneven surface of the corrugated plate, and at the same time improving the compliance and stability of the pressing action; a vibration component 53 is fixedly connected to the upper side surface of the pressing plate body 51, and the vibration component 53 can apply vibrations with a small frequency to the pressing plate body 51 during the pressing process, which helps to disperse the stress concentration caused by welding thermal deformation and promotes a closer fit between the corrugated plate and the pressing surface, thereby improving the uniformity and stability of the pressing effect. At the same time, it also helps the welding heat to spread to the surrounding area and avoid thermal stress concentration. Through the combined method of "rotational compensation + vibration assistance", on the basis of ensuring the stable output of the pressing force, the warping deformation is further suppressed, the weld forming consistency and reliability are improved, and the adaptability and welding quality of the entire welding fixture system are effectively enhanced; The vibration component 53 is preferably a vibrator, and the rotating bearing 52 is preferably a universal bearing.

[0051] Specifically, as Figure 6As shown, the present application also discloses a pressing method for corrugated plate welding, including a pressing device for corrugated plate welding. The real-time temperature on the side of the corrugated plate weld is T, and the preset target control temperature is T 预 , the preset temperature upper limit threshold is T 高 =T 预 +ΔT, the preset temperature lower limit threshold is T 低 =T 预 -ΔT, ΔT is the allowable temperature error range, and the method further includes the following steps: S1: The first clamping mechanism 1 and the second clamping mechanism 2 are aligned and clamp the peak nodes of two adjacent corrugated plates; S2: By rotating the connecting support rod 4 threadedly connected to the pressing support mechanism 3, the connecting support rod 4 moves downward in the vertical direction, and the connecting support rod 4 drives the corrugated plate pressing mechanism 5 and the heat-conducting top pressing plate assembly 61 to move downward and press the side of the corrugated plate weld; S3: When welding the corrugated plate weld, the temperature detection component 62 on the heat-conducting top pressing plate assembly 61 detects the temperature on the side of the corrugated plate weld in real time; S4: When the temperature detection component 62 detects that the current temperature T≥T 高 , the temperature detection component 62 triggers the coolant circulation pump 65 and the heat dissipation component 66 to start. The coolant circulation pump 65 drives the coolant in the coolant storage tank 64 to circulate through the heat-conducting pipe assembly 63. The heat-conducting pipe assembly 63 pumps the coolant from the coolant storage tank 64 into the heat-conducting top pressing plate assembly 61, thereby realizing active cooling of the target area; S5: When the temperature detection component 62 detects that the current temperature T≤T 低 , the temperature detection component 62 triggers the coolant circulation pump 65 and the heat dissipation component 66 to stop, stopping the coolant circulation flow, thereby avoiding overcooling and reducing energy consumption.

[0052] In the present application, through the alignment and clamping actions of the first clamping mechanism 1 and the second clamping mechanism 2, the peak nodes of adjacent corrugated plates are stably fixed, ensuring accurate position positioning and initial constraint of the corrugated plates before welding; the operator rotates the connecting support rod 4 threadedly connected to the pressing support mechanism 3, so that the connecting support rod 4 moves downward in the vertical direction, driving the corrugated plate pressing mechanism 5 and the heat-conducting top pressing plate assembly 61 to move downward synchronously and closely adhere to the side of the corrugated plate weld to complete the pressing action; when welding is performed, the temperature detection component 62 on the heat-conducting top pressing plate assembly 61 detects the temperature T in the side area of the weld in real time; if T≥T 高 =T 预+ΔT, the temperature detection component 62 triggers the start of the coolant circulation pump 65 and the heat dissipation component 66. The coolant circulation pump 65 causes the coolant to flow from the coolant storage tank 64 into the heat conduction top pressing plate component 61 through the heat conduction pipe component 63, realizing active cooling of the welding heat source area to suppress the warping of the corrugated plate caused by thermal expansion. When it is detected that T ≤ T 低 =T 预 -ΔT, the temperature detection component 62 triggers the shutdown of the coolant circulation pump 65 and the heat dissipation component 66, stopping the coolant flow to prevent the energy consumption waste and reverse thermal stress impact caused by overcooling. Through the multi-step linkage operation of "clamping and positioning, vertical pressing, temperature control closed-loop, and dynamic cooling", this method constructs a precise and efficient corrugated plate welding assistance system, which can significantly improve the geometric stability of the weld and the controllability of the thermal field, and enhance the forming consistency and structural quality reliability of the welding process.

[0053] In this application, by setting the upper and lower limit thresholds T 高 and T 低 , and setting the temperature allowable error range ΔT, a temperature hysteresis control mechanism can be introduced, and a hysteresis window of ΔT is always maintained between each start and stop, preventing frequent start and stop phenomena caused by temperature fluctuations near T 预 , thereby improving the operating stability of the cooling system, extending the service life of the pump body and radiator, and improving energy utilization efficiency.

[0054] The implementation principle of a pressing device and method for corrugated plate welding in an embodiment of this application is as follows: A pressing device for corrugated plate welding aligns the first clamping mechanism 1 and the second clamping mechanism 2 and respectively clamps the adjacent wave crest nodes of the corrugated plate to provide overall support. Subsequently, by rotating the connecting support rod 4 threadedly connected to the pressing and supporting mechanism 3, the connecting support rod 4 moves downward in the vertical direction, thereby driving the corrugated plate pressing mechanism 5 connected to the lower end and the heat conduction top pressing plate component 61 connected to the corrugated plate pressing mechanism 5 to move downward as a whole, and then pressing the heat conduction top pressing plate component 61 against the surface of the side of the weld in the area to be welded of the corrugated plate, realizing the pressing operation on the side of the weld. During the welding process, the temperature detection component 62 monitors the temperature state of the contact area between the heat-conducting top pressing plate component 61 and the corrugated plate in real time. When the temperature reaches the preset upper limit, the temperature detection component 62 triggers the start of the coolant circulation pump 65 and the heat dissipation component 66 through electrical connection. The coolant circulation pump 65 pumps the coolant from the coolant storage tank 64 to the inside of the heat-conducting top pressing plate component 61 through the heat-conducting pipe component 63 for cooling treatment. At the same time, the heat dissipation component 66 arranged on the side wall of the coolant storage tank 64 assists in accelerating the heat dissipation and cooling process. When it is detected that the temperature drops to the preset lower limit, the temperature detection component 62 triggers the coolant circulation pump 65 and the heat dissipation component 66 to stop again, thus forming a temperature control closed loop. Through the structural linkage and thermal control coordination method, the present application can not only stabilize the position of the corrugated plate during the welding process and prevent the warping of the plate caused by welding stress, but also reduce the risk of local deformation caused by heat input through active temperature control, thereby significantly improving the forming quality, welding consistency and product structure stability of the corrugated plate lap welding; The corrugated plate pressing mechanism 5 is used to realize the vertical pressing and dynamic fitting of the corrugated plate weld area; the rotating bearings 52 are respectively connected to the connecting support rod 4 and the pressing plate body 51, and are used to provide a certain rotational compensation ability during the pressing process, so that the pressing plate body 51 moves up and down along the vertical direction, avoiding the offset or uneven force of the pressing surface caused by the small displacement of the connecting support rod 4 or the uneven surface of the corrugated plate, and at the same time improving the compliance and stability of the pressing action; a vibration component 53 is fixedly connected to the upper side surface of the pressing plate body 51, and the vibration component 53 can apply a vibration with a small frequency to the pressing plate body 51 during the pressing process, which helps to disperse the stress concentration caused by welding thermal deformation and promotes a closer fit between the corrugated plate and the pressing surface, thereby improving the uniformity and stability of the pressing effect, and at the same time also helps the welding heat to spread to the surrounding area and avoid heat stress concentration. Through the combined method of "rotation compensation + vibration assistance", the present application further suppresses warping deformation, improves the consistency and reliability of weld formation, and effectively improves the adaptability and welding quality of the entire welding tooling system on the basis of ensuring the stable output of the pressing force; A pressing method for corrugated plate welding, through the alignment and clamping actions of the first clamping mechanism 1 and the second clamping mechanism 2, stably fixes the peak nodes of adjacent corrugated plates to ensure accurate position positioning and initial constraint of the corrugated plate before welding; the operator rotates the connecting support rod 4 threadedly connected to the pressing support mechanism 3, so that the connecting support rod 4 moves downward along the vertical direction, driving the corrugated plate pressing mechanism 5 and the heat-conducting top pressing plate component 61 to move downward synchronously and closely adhere to the side of the corrugated plate weld to complete the pressing action; when welding operations are carried out, the temperature detection component 62 on the heat-conducting top pressing plate component 61 detects the temperature T of the side area of the weld in real time; if T≥T 高 =T 预+ΔT, the temperature detection component 62 triggers the start of the coolant circulation pump 65 and the heat dissipation component 66. The coolant circulation pump 65 causes the coolant to flow from the coolant storage tank 64 into the heat conduction top pressing plate component 61 through the heat conduction pipe component 63, realizing active cooling of the welding heat source area to inhibit the warping of the corrugated plate caused by thermal expansion. When it is detected that T≤T 低 =T 预 -ΔT, the temperature detection component 62 triggers the shutdown of the coolant circulation pump 65 and the heat dissipation component 66, stopping the coolant flow to prevent the energy consumption waste and reverse thermal stress impact caused by overcooling. Through the multi-step linkage operation of "clamping and positioning, vertical pressing, temperature control closed-loop, and dynamic cooling", this method constructs a precise and efficient corrugated plate welding assistance system, which can significantly improve the geometric stability of the weld and the controllability of the thermal field, and enhance the forming consistency and structural quality reliability of the welding process.
