Description

Technical Field

[0001] This application relates to the field of cooler fin manufacturing, and more particularly to a cooler fin hydroforming production line. Background Technology

[0002] Cooler fins are key components for enhancing heat exchange efficiency and are widely used in air conditioning, automotive radiators, and electronic equipment cooling. Cooler fins are typically made of metal sheets, which are stamped into the corresponding shape and size using appropriate molds.

[0003] Current stamping equipment mainly consists of a conveying structure and a stamping structure. The conveying structure transports metal sheets to the stamping structure, where the stamping structure stamps the metal sheet raw material to form cooler fins of the corresponding shape. After stamping, the fins are pushed to the unloading station by the next metal sheet to be processed. The completed fins fall off under their own gravity, realizing the function of automatic stacking.

[0004] However, because some fins are quite long, they are prone to bending during the material cutting process, resulting in many defective products. Summary of the Invention

[0005] To improve the yield of fins, this application provides a hydraulic forming production line for cooler fins.

[0006] The cooler fin hydraulic forming production line provided in this application adopts the following technical solution: A cooler fin hydroforming production line includes a stamping machine and a suction assembly. The stamping machine has a loading port and a unloading port at both ends. The loading port is used for passing metal sheets through, and the stamping machine is used to process the metal sheets into fins. The unloading port is used for passing the fins through. The suction assembly includes a suction plate, the height of which is greater than the height of the unloading port. The lower end of the suction plate is provided with a suction port, which is used to generate negative pressure to adsorb the fins.

[0007] By adopting the above technical solution, the metal sheet is fed from the feeding port, the stamping machine stamps the metal sheet into fins of the corresponding shape, and cuts the fins into the corresponding size. After the stamping is completed, the fins move to the air intake component, which supports the fins. When the fins are completely separated from the stamping machine, the air intake is closed, and the fins achieve automatic stacking under their own gravity. Under the action of the air intake component, the possibility of fin deformation during the feeding process is reduced, and the yield of fins is improved.

[0008] Preferably, the air intake assembly further includes an air chamber, the air chamber has an air cavity, the lower end of the air chamber has an air inlet, the outer wall of the air chamber has an air outlet, the air inlet and the air outlet are both connected to the air cavity, the air intake plate is fixedly connected to the inner wall of the air inlet, the air intake port is connected to the air cavity, and there are multiple air intake ports, which are arranged in an array on the air intake plate.

[0009] By adopting the above technical solution, the negative pressure of the air intake is increased by utilizing the Venturi effect. The even distribution of multiple air intakes can stably support the metal sheet, reduce the probability of the metal sheet end sagging due to gravity, and improve the yield of the fins.

[0010] Preferably, it also includes a feeding rack and a guide rod, wherein the height of the feeding rack is less than the height of the feeding port, the feeding rack is used to stack fins, and the lower end of the guide rod is fixedly connected to the feeding rack, and the length direction of the guide rod is vertical.

[0011] By adopting the above technical solution, when the air intake is closed, the fins fall due to their own gravity. The guide rod passes through the hole on the fin and guides the fin, so that the fins are stacked neatly on the unloading rack.

[0012] Preferably, it also includes a connecting pipe, the upper end of the unloading rack is provided with a buffer port, one end of the connecting pipe is connected to the air outlet, and the other end of the connecting pipe is connected to the buffer port.

[0013] By adopting the above technical solution, the air outlet of the buffer port buffers the downward movement of the fins, reduces the impact of the fins falling, and improves the yield of fins.

[0014] Preferably, the air intake assembly further includes a limiting plate, which is slidably connected to the lower end of the air intake plate. The sliding direction of the limiting plate is parallel to the moving direction of the fins, and the limiting plate is used to limit the movement of the fins.

[0015] By adopting the above technical solution, the limiting plate limits the fins so that the timing of the air intake stop is synchronized with the fins' disengagement from the stamping machine, preventing the fins from shifting position and facilitating the guide rod to guide the falling fins, so that the fins are stacked neatly.

[0016] Preferably, the air intake assembly further includes a cover plate, which is slidably connected to the upper end of the air intake plate. The cover plate is used to cover the air intake port. The cover plate has multiple openings, which are evenly spaced along the moving direction of the fins.

[0017] By adopting the above technical solution, the sliding of the cover plate closes the air intake, reducing the shortened service life of the equipment caused by repeated start-stop of the air pump and extending the service life of the equipment.

[0018] Preferably, the air intake assembly further includes a piston plate and a connecting rod. The outer wall of the air chamber is provided with a piston port. The piston plate is slidably connected to the inner wall of the piston port. One end of the connecting rod is fixedly connected to the piston plate, and the other end of the connecting rod is fixedly connected to the cover plate.

[0019] By adopting the above technical solution, when the cover plate completely covers the air intake, the air chamber is blocked from air intake, the air pump works stably, the air pressure in the air chamber gradually decreases, the air pressure difference between the inside and outside of the piston plate overcomes the friction of the piston plate and pushes the piston plate to slide, the cover plate moves to cover the air intake, so that the fins are not affected by negative pressure and fall down automatically, which is convenient for stacking materials.

[0020] Preferably, the intake assembly further includes a mounting plate and a return spring. The mounting plate is disposed between the piston plate and the cover plate. One end of the return spring is fixedly connected to the piston plate, and the other end of the return spring is fixedly connected to the mounting plate.

[0021] By adopting the above technical solution, the pressure difference between the inside and outside of the piston plate allows the piston plate to overcome the elastic force of the return spring and slide, and the return spring facilitates the piston plate to return to its original position.

[0022] Preferably, the air intake assembly further includes a sliding plate, and an air inlet is provided at the end of the air chamber away from the piston port. The sliding plate is slidably connected to the inner wall of the air chamber and is used to cover the air inlet.

[0023] By adopting the above technical solution, when the cover plate covers the air intake, the sliding plate slides to open the air supply port, supplying air into the air chamber, thereby balancing the air pressure and promoting the piston plate to reset.

[0024] Preferably, the air intake assembly further includes a first rack, a third gear, and a second rack. The first rack is fixedly connected to the upper end of the cover plate, the third gear is located above the first rack, and the third gear is rotatably connected to the inner wall of the air chamber around its own axis. The rotation axis of the third gear is horizontal. The second rack is fixedly connected to the end of the sliding plate away from the air inlet. Both the first rack and the second rack are meshed with the third gear, and the sliding direction of the sliding plate is vertical.

[0025] By adopting the above technical solution, the cover plate moves while pushing the sliding plate. When the cover plate covers the air intake, the metal sheet falls off. At this time, the air supply port connects to supply air to the air chamber, which promotes the increase of air pressure in the air chamber, causing the cover plate to reset. The air intake is unobstructed by the metal sheet and the air intake is unobstructed, compensating for the air pressure in the air chamber.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Metal sheets are fed from the feeding port. The stamping machine stamps the metal sheets into fins of the corresponding shape and cuts the fins into the corresponding size. After stamping, the fins move to the suction assembly. The suction assembly supports the fins. When the fins are completely separated from the stamping machine, the suction port is closed. The fins achieve automatic stacking under their own gravity. Under the action of the suction assembly, the possibility of fin deformation during the feeding process is reduced, and the yield of fins is improved. 2. When the air intake is closed, the fins fall due to their own weight. The guide rod passes through the hole on the fin and guides the fin, so that the fins are stacked neatly on the unloading rack. 3. As the cover plate moves, it pushes the sliding plate to move. When the cover plate covers the air intake, the metal sheet falls off. At this time, the air supply port connects to supply air to the air chamber, which promotes the increase of air pressure in the air chamber, causing the cover plate to reset. The air intake is unobstructed by the metal sheet and the air intake is unobstructed, compensating for the air pressure in the air chamber. Attached Figure Description

[0052] The implementation principle of a cooler fin hydraulic forming production line according to an embodiment of this application is as follows: the conveying component 2 conveys the metal sheet through the feeding port 11 of the stamping machine 1. The stamping machine 1 processes the metal sheet into fins and cuts them off. The fins are discharged from the unloading port 12. The suction plate 42 adsorbs the fins, and the limiting member 45 limits the fins. When the fins are completely separated from the stamping machine 1, the fins cover the suction port 421, which obstructs the air intake. The air pressure in the air chamber 41 is further reduced. The piston plate 462 moves over the obstruction and pushes the cover plate 461 to move to further cover the suction port 421. The fins are not affected by the negative pressure of the suction port 421 and fall onto the unloading rack 32.
