[0001] This invention relates to the field of heat exchanger water-cooled plate processing, and more specifically, to a heat exchanger water-cooled plate processing equipment and method. Background Technology

[0002] With the continuous development of new energy vehicles, lithium batteries have been widely used as energy storage. Since lithium batteries need to dissipate heat during driving, a heat exchanger water cooling plate is usually installed at the bottom of the lithium battery.

[0003] This heat exchanger water-cooled plate is formed by welding two plates together, and water channels are formed on one of the water-cooled plates by stamping.

[0004] Currently, the stamping of water-cooled plates still relies on upper and lower stamping dies. During the stamping process, the water-cooled plate is manually placed onto the upper stamping die, which is relatively inefficient.

[0005] Therefore, there is an urgent need to provide a heat exchanger water-cooled plate processing equipment with automatic feeding capability to improve the working efficiency of water-cooled plate stamping. Summary of the Invention

[0006] The purpose of this invention is to provide a heat exchanger water-cooled plate processing equipment and method, which can realize fully automatic feeding and punching out water channels for the water-cooled plate.

[0007] To achieve the above objectives, the present invention provides a heat exchanger water-cooled plate processing equipment, including a stamping device and a transmission line. The stamping device includes an upper stamping die and a lower stamping die. The transmission line includes a conveying track disposed on both sides of the upper stamping die and the lower stamping die. A self-driven conveying plate is disposed on the conveying track, and a pneumatic clamping bar is disposed on the bottom side of the self-driven conveying plate.

[0008] Preferably, the heat exchanger water-cooled plate processing equipment further includes a multi-faceted central column capable of rotation, and each face of the multi-faceted central column is provided with a pair of stamping upper dies and stamping lower dies of different specifications.

[0009] Preferably, a drive motor is connected to the bottom of the multifaceted center column, the drive motor is mounted on a base, an inverted first L-shaped frame is fixed to the base, and a rotating shaft is provided on the top of the multifaceted center column, which rotates on the first transverse extension plate of the first L-shaped frame.

[0010] Preferably, each face of the multi-faceted central column is provided with a first groove and a second groove, the first groove being located above the second groove, the rear side of the upper stamping die sliding on the first groove, and the rear side of the lower stamping die sliding on the second groove.

[0011] Preferably, a guide rod is provided in both the first and second slide grooves, and a connecting plate is fixedly connected to the rear side of both the upper and lower stamping dies. A slider that slides in the first or second slide groove and is sleeved on the guide rod is fixedly connected to the rear side of the connecting plate.

[0012] Preferably, a first spring and a second spring are respectively sleeved on the guide rod in the first groove on both sides of the corresponding slider, and a third spring and a fourth spring are respectively sleeved on the guide rod in the second groove on both sides of the corresponding slider.

[0013] Preferably, a support plate is mounted on the base via multiple support rods, and a support block is provided on the support plate below the lower stamping die; an inverted second L-shaped frame is provided on the support plate, and a hydraulic cylinder is mounted on the second lateral extension plate of the second L-shaped frame, the hydraulic cylinder being detachably connected to the upper stamping die.

[0014] Preferably, the upper stamping die is provided with a plurality of protrusions with slots, a pressure plate is fixedly connected to the cylinder shaft of the hydraulic cylinder, and a push rod that can be inserted into the slot is fixedly connected to the bottom of the pressure plate.

[0015] Preferably, an inductive switch is provided on the inner side of the second L-shaped frame, and a sensor paired with the inductive switch is provided on the side of the self-driven conveying plate.

[0016] The present invention also provides a method for processing water-cooled plates for heat exchangers. The processing method uses the aforementioned processing equipment and includes: clamping the water-cooled plate to be stamped with pneumatic clamping bars and transporting it to the lower stamping die, and stamping out the required water channels with the upper stamping die. The upper and lower stamping dies are arranged on the side of a multi-faceted central column that can rotate and can switch between different specifications of upper and lower stamping dies by rotating the multi-faceted central column.

[0017] According to the above technical solution, the heat exchanger water-cooled plate processing equipment of the present invention uses pneumatic clamping bars to clamp both sides of the water-cooled plate that needs to have water channels punched. A self-driven conveying plate travels on a conveyor track and transports the water-cooled plate to the lower stamping die. After releasing the pneumatic clamping bars, the self-driven conveying plate continues to travel, and the lower stamping die moves down to punch water channels into the water-cooled plate. After stamping, the water-cooled plate can be picked up by a robotic arm with suction cups on one side or manually and transferred to another production line. Therefore, this heat exchanger water-cooled plate processing equipment can achieve fully automatic feeding and punching of water channels into the water-cooled plate.

Detailed Implementation

[0026] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] In this invention, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0028] See Figure 1-4 The heat exchanger water-cooled plate processing equipment shown includes a stamping device and a transmission line. The stamping device includes an upper stamping die 5 and a lower stamping die 4. The transmission line includes a conveying track 7 arranged on both sides of the upper stamping die 5 and the lower stamping die 4. A self-driven conveying plate 15 is arranged on the conveying track 7. A pneumatic clamping bar 27 is arranged on the bottom side of the self-driven conveying plate 15.

[0029] Through the implementation of the above technical solution, the heat exchanger water-cooled plate processing equipment can clamp both sides of the water-cooled plate that needs to have water channels punched by relying on pneumatic clamping bars 27. The self-driven conveying plate 15 travels on the conveying track 7 and transports the water-cooled plate to the stamping die 4. After releasing the pneumatic clamping bars 27, the self-driven conveying plate 15 continues to travel. At this time, the stamping die 4 moves down to punch water channels into the water-cooled plate. After the stamping is completed, the water-cooled plate can be picked up by a robot arm with suction cups on one side or manually and transferred to other production lines. Therefore, this heat exchanger water-cooled plate processing equipment can achieve fully automatic feeding and punching of water channels into the water-cooled plate.

[0030] In this embodiment, the heat exchanger water-cooled plate processing equipment further includes a rotatable multi-faceted central column 16. Each face of the multi-faceted central column 16 is provided with a pair of stamping upper dies 5 and stamping lower dies 4 of different specifications. Through the rotation of the multi-faceted central column 16, the stamping upper dies 5 and stamping lower dies 4 of different specifications can rotate in pairs to the upper and lower positions of the conveying track 7, for stamping water channels of different specifications onto the water-cooled plate. This solves the current problem of having to disassemble and replace the stamping upper dies 5 and stamping lower dies 4 when stamping water channels of different specifications, thus improving stamping efficiency. The multi-faceted central column 16 is a four-sided column with four identical faces.

[0031] In this embodiment, a drive motor 17 is connected to the bottom of the multifaceted central column 16. The drive motor 17 is mounted on a base 18, and an inverted first L-shaped frame 14 is fixedly connected to the base 18. A rotating shaft 10 is provided at the top of the multifaceted central column 16, which rotates on a first transverse extension plate of the first L-shaped frame 14. This arrangement allows the upper end of the multifaceted central column 16 to rotate stably, thereby improving the stability of the multifaceted central column 16, preventing collapse, and increasing safety in use.

[0032] In this embodiment, each face of the multi-faceted central column 16 is provided with a first sliding groove 19 and a second sliding groove 30. The first sliding groove 19 is disposed above the second sliding groove 30. The rear side of the upper stamping die 5 slides on the first sliding groove 19, and the rear side of the lower stamping die 4 slides on the second sliding groove 30. This arrangement allows the upper stamping die 5 and the lower stamping die 4 to slide stably vertically. Multiple first sliding grooves 19 and second sliding grooves 30 can be arranged side-by-side on each face, for example, two side-by-side.

[0033] In this embodiment, guide rods 29 are provided in both the first slide groove 19 and the second slide groove 30. Connecting plates 26 are fixedly connected to the rear sides of both the upper stamping die 5 and the lower stamping die 4. A slider 24, which slides within the first slide groove 19 or the second slide groove 30 and is sleeved on the guide rods 29, is fixedly connected to the rear side of the connecting plate 26. The guide rods 29 further enhance the vertical sliding stability of the upper stamping die 5 and the lower stamping die 4.

[0034] In this embodiment, a first spring 21 and a second spring 22 are respectively fitted on the guide rod 29 in the first slide groove 19 on both sides of the corresponding slider 24, and a third spring 25 and a fourth spring 23 are respectively fitted on the guide rod 29 in the second slide groove 30 on both sides of the corresponding slider 24. The installation order of the first spring 21, the second spring 22, the third spring 25 and the fourth spring 23 from top to bottom is: first spring 21, second spring 22, fourth spring 23 and third spring 25. The first spring 21 and the second spring 22 provide elastic limiting for the upper stamping die 5, and the fourth spring 23 and the third spring 25 provide elastic limiting for the lower stamping die 4.

[0035] Furthermore, a support plate 2 is mounted on the base 18 via multiple support rods 1, and a support block 3 is provided on the support plate 2 below the lower stamping die 4. An inverted second L-shaped frame 8 is provided on the support plate 2, and a hydraulic cylinder 9 is mounted on the second transverse extension plate of the second L-shaped frame 8. The hydraulic cylinder 9 is detachably connected to the upper stamping die 5. When the lower stamping die 4 moves onto the support block 3, the fourth spring 23 is in a compressed state. The fourth spring 23 can stably press the lower stamping die 4 onto the support plate 2. This is achieved as follows: when the lower stamping die 4 is not on the support block 3, the bottom surface of the lower stamping die 4 is slightly lower than the upper surface of the support block 3. When the two are about to contact, the contact surface is curved, and the two slide in contact. Under the guidance of this curved surface, the lower stamping die 4 is gradually moved upward, thereby moving onto the support block 3. At this time, the fourth spring 23 is in a compressed state. In addition, when the upper stamping die 5 rotates to the position below the hydraulic cylinder 9, the upper stamping die 5 is connected to the hydraulic cylinder 9, and the upper stamping die 5 is driven to stamp through the hydraulic cylinder 9. Therefore, it is not necessary for each upper stamping die 5 to carry a cylinder, but only one hydraulic cylinder 9 is needed, thereby saving costs and simplifying the equipment.

[0036] In this embodiment, the upper stamping die 5 is provided with multiple protrusions 13 having slots 12. A pressure plate 20 is fixedly connected to the cylinder shaft of the hydraulic cylinder 9, and a push rod 11 that can be inserted into the slot 12 is fixedly connected to the bottom of the pressure plate 20. The usage is as follows: when the upper stamping die 5 moves to a position below the push rod 11, the push rod 11 is located above the protrusions 13 and is not in contact. The hydraulic cylinder 9 drives the push rod 11 downwards and extends into the slot 12, and then continues to press the upper stamping die 5 to achieve stamping. After stamping is completed, the push rod 11 moves upwards, and the upper stamping die 5 returns to its original position under the reset action of the first spring 21 and the second spring 22. At this time, the push rod 11 is still located above the protrusions 13 and remains in a non-contact state, thus not affecting the rotation and switching of the upper stamping die 5. This eliminates the need for manual disassembly and installation between the hydraulic cylinder 9 and the upper stamping die 5, increasing efficiency.

[0037] Furthermore, to facilitate the automatic alignment of the self-driven conveyor plate 15 and accurately place the water-cooled plate at the designated position on the stamping die 4, an induction switch 28 is provided on the inner side of the second L-shaped frame 8, and a sensor 6 paired with the induction switch 28 is provided on the side of the self-driven conveyor plate 15. When the induction switch 28 senses that the sensor 6 is directly in front of it, it sends a command to pause the movement of the self-driven conveyor plate 15 and a command to open the pneumatic clamping bar 27, causing the water-cooled plate to fall into the designated position, and then the self-driven conveyor plate 15 continues to move.

[0038] The self-driven conveying plate 15 of the present invention can be equipped with a corresponding drive motor 17, and the drive motor 17 is equipped with a rolling wheel and a matching driven wheel that can rub and roll on the conveying track 7.

[0039] The present invention also provides a method for processing water-cooled plates for heat exchangers. The processing method uses the aforementioned processing equipment and includes: clamping the water-cooled plate to be stamped by a pneumatic clamping bar 27 and transporting it to the lower stamping die 4, and stamping out the required water channels by an upper stamping die 5. The upper stamping die 5 and the lower stamping die 4 are arranged on the side of a multi-faceted central column 16 that can rotate on its own, and different specifications of the upper stamping die 5 and the lower stamping die 4 can be switched by rotating the multi-faceted central column 16.

However, the present invention is not limited to the specific details of the above embodiments.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0042] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
