Description

Technical Field

[0001] This utility model belongs to the field of evaporator manufacturing technology, and in particular to an evaporator fin pressing device. Background Technology

[0002] In the evaporator manufacturing process, fin bonding is a critical step. The quality of fin bonding directly affects the evaporator's heat dissipation performance and overall service life. Existing bonding equipment can meet basic bonding requirements, but its pre-compression capacity is weak, failing to effectively correct twisting or misalignment of the fins during production and transportation. Fins entering the formal bonding stage in an uneven state reduces and unevens the contact area between the bonding column and the fins, affecting bonding uniformity and stability, reducing production efficiency, and increasing costs.

[0003] A search revealed a Chinese patent document (authorization announcement number CN206561607U), which discloses a pressing device comprising a pressure plate for supporting an upper pressure head, a floating plate for supporting a lower mold, a lifting mechanism for connecting and driving the pressure plate to move vertically and applying pressure to the floating plate, and a support frame for supporting the lifting mechanism. The pressure plate is fixed to the lifting mechanism, and the floating plate is located below the pressure plate. This pressing device can also implement precise pressure and time control for individual products, effectively ensuring product quality. While the device can meet basic pressing requirements, its pre-compression capability is weak, and it cannot effectively correct the twisting or offset of the fins during production and transportation. The fins enter the formal pressing stage in an uneven state, resulting in a reduced and uneven contact area between the pressing column and the fins, affecting the uniformity and stability of the pressing, reducing production efficiency, and increasing costs. Utility Model Content

[0004] The purpose of this invention is to provide an evaporator fin pressing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an evaporator fin pressing device, comprising a support frame for supporting evaporator fins, a fixing plate installed on the top of the support frame, four fixing rods for support and guidance welded to the top of the fixing plate, an mounting plate installed on the top of the fixing rods, and a power box and a telescopic rod installed on the top of the mounting plate;

[0006] The movable part of the telescopic rod is connected to a connecting plate, and a pressure plate is welded to the bottom of the connecting plate. The pressure plate has a cross groove for guidance inside, and a cross moving plate is slidably installed inside the cross groove. A connecting column is connected to one side of the cross moving plate.

[0007] Preferably, a spring is connected to the other side of the cross-shaped moving plate, and the end of the spring is connected to the inner top wall of the cross groove.

[0008] Preferably, a limiting plate for limiting the movement of the cross plate is welded to the vertical inner wall of the cross groove, and a cross pressing plate is connected to the end of the connecting column away from the spring.

[0009] Preferably, a pressing column for pressing evaporator fins is installed at the end of the cross pressing plate away from the connecting column, and the pressing column has a hollow groove inside.

[0010] Preferably, the support frame has a base plate welded inside, and the surface of the base plate is provided with a T-shaped groove for movement.

[0011] Preferably, a slider is slidably installed inside the T-shaped groove, and an evaporator heat exchange tube placement plate for fixing is installed on the top of the slider, with heat exchange tubes installed on the top of the evaporator heat exchange tube placement plate.

[0012] Preferably, the surface of the fixing plate is also provided with a T-shaped groove, and the interior of the T-shaped groove is provided with a fin pressing inlet for the evaporator fins to pass through.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This evaporator fin pressing device benefits from the structure of the cross-shaped pressing plate. When the pressing column contacts the evaporator fins, the pressing column drives the cross-shaped pressing plate connecting column and the cross-shaped moving plate to compress the spring. The spring contracts, which plays a role in pre-pressing and buffering, preventing hard contact between the pressing column and the evaporator fins, thus protecting the equipment from damage. Compared with the weak pre-pressing capacity of traditional evaporator fin pressing devices, this structure can improve the pre-pressing capacity, effectively correct the twisting or displacement of the fins during production and transportation, improve the uniformity and stability of pressing, increase production efficiency, and reduce costs.

[0015] This evaporator fin pressing device, thanks to the structure of the T-shaped slide groove, allows the heat exchange tubes to be installed on the evaporator heat exchange tube placement plate. The slider moves the evaporator heat exchange tube placement plate and the heat exchange tubes to below the fin pressing inlet, and places the evaporator fins on the fin pressing inlet through the T-shaped slide groove. This structure improves the accuracy of the evaporator fin positioning. Attached Figure Description

In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The evaporator fin pressing device shown includes a support frame 1 for supporting the evaporator fins. The support frame 1 is used to bear the weight of the evaporator and the entire device. It is usually made of high-strength metal material and has good rigidity and stability. A fixing plate 106 is installed on the top of the support frame 1. Four fixing rods 108 for support and guidance are welded to the top of the fixing plate 106. An mounting plate 2 is installed on the top of the fixing rods 108. A power box 201 and a telescopic rod 202 are installed on the top of the mounting plate 2.

[0027] The movable part of the telescopic rod 202 is connected to the connecting plate 203. The bottom of the connecting plate 203 is welded to the pressure plate 204. The inside of the pressure plate 204 is provided with a cross groove 205 for guidance. A cross moving plate 207 is slidably installed inside the cross groove 205. A connecting column 3 is connected to one side of the cross moving plate 207. When the movable part of the telescopic rod 202 extends, the telescopic rod 202 drives the connecting plate 203, the pressure plate 204 and the pressing column 303 to move toward the evaporator fins. Finally, the pressing column 303 presses down on the evaporator fins. The evaporator fins enter the heat exchange tube 105 through the fin pressing inlet 107. The above steps are repeated to complete the evaporator fin pressing.

[0028] A spring 206 is connected to the other side of the cross-shaped moving plate 207. A damping mechanism is provided between the spring 206 and the cross groove 205. The end of the spring 206 is connected to the inner top wall of the cross groove 205. A limiting plate 301 for limiting the movement of the cross-shaped moving plate 207 is welded to the vertical inner wall of the cross groove 205. A cross-shaped pressing plate 302 is connected to the end of the connecting column 3 away from the spring 206. A pressing column 303 for pressing the evaporator fins is installed at the end of the cross-shaped pressing plate 302 away from the connecting column 3. The pressing column 303 is made of high-quality steel and undergoes precise surface treatment. The lower end of the pressing column 303 is typically equipped with... Equipped with a rubber head with anti-slip texture, the rubber head increases friction with the fins, preventing fin slippage and avoiding damage. The pressing column 303 has a hollow groove 304 inside. When the pressing column 303 contacts the evaporator fins, it drives the cross pressing plate 302, connecting column 3, and cross moving plate 207 to compress the spring 206. The spring 206 contracts, providing pre-compression and buffering, preventing hard contact between the pressing column 303 and the evaporator fins, thus protecting the equipment from damage. The heat exchange tube 105 can enter the hollow groove 304 to complete the pressing of the evaporator fins.

[0029] The support frame 1 has a base plate 101 welded inside. The surface of the base plate 101 is provided with a T-shaped slide groove 102 for movement. A slider 103 is slidably installed inside the T-shaped slide groove 102. An evaporator heat exchange tube placement plate 104 for fixing is installed on the top of the slider 103. A heat exchange tube 105 is installed on the top of the evaporator heat exchange tube placement plate 104. The surface of the fixing plate 106 is also provided with a T-shaped slide groove 102. The inside of the T-shaped slide groove 102 is provided with a fin pressing inlet 107 for the evaporator fins to pass through. The heat exchange tube 105 is installed on the evaporator heat exchange tube placement plate 104. The slider 103 drives the evaporator heat exchange tube placement plate 104 and the heat exchange tube 105 to move below the fin pressing inlet 107. The evaporator fins are placed on the fin pressing inlet 107 through the T-shaped slide groove 102.

[0030] Working principle

[0031] In use, the evaporator fin pressing device first installs the heat exchange tube 105 on the evaporator heat exchange tube placement plate 104. The slider 103 moves the evaporator heat exchange tube placement plate 104 and the heat exchange tube 105 to below the fin pressing inlet 107. The evaporator fins are then placed on the fin pressing inlet 107 through the T-shaped sliding groove 102. The movable part of the telescopic rod 202 extends, and the telescopic rod 202 moves the connecting plate 203, the pressure plate 204, and the pressing column 303 toward the evaporator fins. Finally, the pressing column 303 presses down on the evaporator fins. The evaporator fins enter the heat exchange tube 105 through the fin pressing inlet 107. The above steps are repeated to complete the evaporator fin pressing. When the pressing column 303 contacts the evaporator fins, the pressing column 303 drives the cross pressing plate 302 connecting column 3 and cross moving plate 207 to squeeze the spring 206. The spring 206 contracts, which plays a pre-pressing and buffering role, preventing the pressing column 303 from making hard contact with the evaporator fins, thereby protecting the equipment from damage. The heat exchange tube 105 can enter the hollow groove 304 to complete the evaporator fin pressing.
