Description

Technical Field

[0001] This invention relates to the field of metal cutting equipment technology, and in particular to a laser cutting device for processing water-cooled plates with high efficiency cooling. Background Technology

[0002] Water-cooled plates are a key component of automotive cooling systems, primarily used for efficient heat dissipation and temperature control. They are widely used, especially in new energy vehicles, and are suitable for precise temperature control of high-power equipment such as power batteries and motors in new energy vehicles.

[0003] Brazed water-cooled plates typically consist of two metal plates (such as aluminum plates), one of which is stamped to form an internal flow channel structure, and the other is a cover plate, which is sealed together by brazing.

[0004] The aluminum sheet raw material for brazed water-cooled plates needs to be cut using laser cutting during processing to ensure the processing accuracy of the sheet material. During the continuous cutting process, the laser cutting head generates a large amount of heat, requiring the laser's operating temperature to be maintained below 45℃ to avoid output power fluctuations or damage to optical components, and to prevent power reduction if the temperature exceeds 45℃. Therefore, the laser cutting machine needs to be cooled down promptly during operation to ensure cutting quality.

[0005] Existing laser cutting heads dissipate heat through externally installed cooling pipes, where heat exchange is achieved using a cooling medium. However, the cooling system can only adjust its cooling capacity by regulating the flow rate of the cooling medium. In emergency situations such as rapid temperature increases in the laser cutting head, it cannot quickly adjust the cooling capacity to cope with the situation, resulting in untimely cooling of the laser cutting head. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency cooling water-cooled plate processing laser cutting equipment to solve the problem that the existing laser cutting machine cooling system cannot quickly adjust the cooling capacity when cooling the laser cutting head.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cooling laser cutting device for processing water-cooled plates, comprising:

[0008] Laser cutting head;

[0009] The main cooling module includes a connecting ring and a first cooling tube body. The connecting ring is fixedly installed on the laser cutting head. The two first cooling tube bodies are symmetrically arranged along the axis of the laser cutting head. The first cooling tube bodies contact the outer wall of the laser cutting head. The first cooling tube body is provided with a first insertion gap formed by the first cooling tube being wound in an "S" shape.

[0010] The auxiliary cooling module includes a second cooling tube body, a connector, and a drive motor. The end of the second cooling tube body passes through the arc-shaped guide hole on the connecting ring and is fixedly installed on the connector. The second cooling tube body is provided with a second insertion gap for splicing with the first cooling tube body. One end of the connector is provided with a guide slope and the other end is provided with a rack. The drive motor is fixedly installed on the laser cutting head. The motor shaft of the drive motor is connected to a drive gear, and the drive gear meshes with the rack.

[0011] The backup cooling module includes a cooling plate and a connector. The cooling plate has a cooling medium flow channel, and the connector has an elastic element on the back. One end of the elastic element is fixedly installed on the connector, and the other end contacts the inner wall of the cooler housing.

[0012] As a further description of the above technical solution:

[0013] The laser cutting head is fixedly mounted on the mover of the Z-axis linear module, the Z-axis linear module is fixedly mounted on the mover of the X-axis linear module, and the X-axis linear module is fixedly mounted on the gantry.

[0014] As a further description of the above technical solution:

[0015] The cooler housing is detachably mounted on the laser cutting head.

[0016] As a further description of the above technical solution:

[0017] The cooler housing is threaded onto the laser cutting head, and the surface of the cooler housing is provided with several circumferentially arranged ribs.

[0018] As a further description of the above technical solution:

[0019] Several temperature sensors are arranged around the laser cutting head on the inner wall of the cooler housing.

[0020] As a further description of the above technical solution:

[0021] The outer edge of the connecting ring is provided with an arc-shaped retaining edge, and the rack contacts the inner wall of the arc-shaped retaining edge.

[0022] As a further description of the above technical solution:

[0023] The surface of the connecting ring is provided with several parallel positioning posts, which are arranged along the length of the rack.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, when the laser cutting head cuts the raw material sheet of the water-cooled plate for new energy vehicles, cooling is achieved through a cooling system composed of a main cooling module, a secondary cooling module, and a backup cooling module. Under normal conditions, the first cooling tube of the main cooling module and the second cooling tube of the auxiliary cooling module are separated. At this time, the first and second cooling tubes cool the laser cutting head. In an emergency where a rapid increase in cooling capacity is required, the backup cooling module is activated, cooling medium is introduced into the cooling plate, and the drive gear on the motor shaft drives the rack to slide on the connecting ring, causing the connector to move away and no longer press against the connector seat of the cooling plate. The connector seat is reset under the elastic force of the elastic element on the back, and the cooling plate contacts the laser cutting head. During this process, the second cooling tube and the first cooling tube are connected through the first and second insertion gaps, which increases the cooling tube density and cooling capacity of the laser cutting head at the first cooling tube, and effectively improves the overall cooling capacity of the cooling system. This solves the problem that the existing laser cutting machine cooling system cannot quickly adjust the cooling capacity when cooling the laser cutting head, and effectively copes with emergency situations where the laser cutting head temperature rises rapidly and remains at a high temperature without decreasing.

[0026] 2. In this invention, to facilitate the maintenance of the main cooling module, auxiliary cooling module, and backup cooling module, the cooler housing adopts a detachable design. To facilitate repeated disassembly and assembly of the cooler housing, it is preferably fixed to the laser cutting head by a threaded connection, and the surface ribs facilitate rotation.

[0037] Please see Figure 1-5 This invention provides a technical solution: a high-efficiency cooling laser cutting device for processing water-cooled plates, comprising:

[0038] Laser cutting head 1;

[0039] The main cooling module 2 includes a connecting ring 21 and a first cooling tube body 22. The connecting ring 21 is fixedly installed on the laser cutting head 1. The two first cooling tube bodies 22 are symmetrically arranged along the axis of the laser cutting head 1. The first cooling tube body 22 contacts the outer wall of the laser cutting head 1. The first cooling tube body 22 is provided with a first insertion gap 221 formed by the first cooling tube being wound in an "S" shape. The end of the first cooling tube body 22 is fixedly installed on the connecting ring 21. The first cooling tube body 22 is provided with a first coolant outlet and a first coolant inlet. The first coolant outlet and the first coolant inlet are both located above the connecting ring 21. The first coolant inlet is connected to the first coolant main pipe through the first coolant inlet branch pipe. The first coolant outlet is connected to the first return main pipe through the first coolant outlet pipe. The first coolant main pipe is connected to the first storage tank of the cooling medium. The first return main pipe is connected to the first storage tank. A first heat exchanger is provided on the first return main pipe to reduce the temperature of the discharged cooling medium. A dynamic balance valve can be provided on the first coolant inlet branch pipe to ensure stable flow.

[0040] The auxiliary cooling module 3 includes a second cooling tube body 31, a connector 32, and a drive motor 33. The two second cooling tube bodies 31 are symmetrically arranged along the axis of the laser cutting head 1. The ends of the second cooling tube bodies 31 pass through the arc-shaped guide holes 211 on the connecting ring 21 and are fixedly installed on the connector 32. The second cooling tube body 31 is provided with a second insertion gap 311 for splicing with the first cooling tube body 22. One end of the connector 32 is provided with a guide slope 321, and the other end is provided with a rack 322. The drive motor 33 is fixedly installed on the laser cutting head 1. The drive gear is connected to the motor shaft of the drive motor 33. The drive gear meshes with the rack 322. The coolant supply and return process of the auxiliary cooling module 3 is the same as that of the main cooling module 2. The second storage tank supplies the cooling medium through the second coolant main pipe. The second return pipe reduces the temperature of the discharged cooling medium through the second heat exchanger and then returns the cooling medium to the second storage tank. The connection between the second cooling tube body 31 and the second coolant main pipe and the second return pipe is the same.

[0041] The backup cooling module 4 includes a cooling plate 41 and a connector 42. The two cooling plates 41 are symmetrically arranged along the axis of the laser cutting head 1. The cooling plates 41 contact the outer wall of the laser cutting head 1. Cooling medium channels are provided inside the cooling plates 41. The inlet of the cooling medium channels is connected to the third liquid inlet branch pipe, and the outlet is connected to the third liquid return branch pipe. The third liquid inlet branch pipe passes through the notch 212 on the connecting ring 21 and is fixedly connected to the connector 42. The third liquid return branch pipe passes through the notch 212 and is fixedly connected to the connector 42. An elastic element is provided on the back of the connector 42. One end of the elastic element is fixedly installed on the connector 42, and the other end contacts the inner wall of the cooler housing 5. The connector 42 has an arc surface on the side facing the connector 32. The cooling medium supply and discharge methods of the cooling plates 41 in the backup cooling module 4 are the same as those of the first cooling pipe body 22 and the second cooling pipe body 31, and will not be described in detail.

[0042] The laser cutting head 1 is fixedly mounted on the mover of the Z-axis linear module 11, the Z-axis linear module 11 is fixedly mounted on the mover of the X-axis linear module 12, and the X-axis linear module 12 is fixedly mounted on the gantry 13, so that the laser cutting head 1 can move and cut.

[0043] Several temperature sensors are arranged circumferentially around the laser cutting head 1 on the inner wall of the cooler housing 5. The temperature sensors are used to monitor the temperature of the laser cutting head 1, effectively monitor the operating temperature of the laser cutting head 1, and thus effectively control the operating temperature of the laser cutting head 1.

[0044] Working principle: When the laser cutting head 1 cuts the raw material plate of the water-cooled plate of new energy vehicle, it is cooled by a cooling system composed of the main cooling module 2, the auxiliary cooling module 3, and the backup cooling module 4.

[0045] See appendix Figure 4 Under normal conditions, the first cooling tube body 22 of the main cooling module 2 and the second cooling tube body 31 of the auxiliary cooling module 3 are separated. The cooling plate 41 of the standby cooling module 4 is pushed towards the inner wall of the cooler housing 5 by the connector 32 above the connector seat 42, causing the cooling plate 41 to detach from the laser cutting head 1. Therefore, the standby cooling module 4 is not activated. At this time, the first cooling tube body 22 and the second cooling tube body 31 cool the laser cutting head 1.

[0046] See appendix Figure 5In an emergency where rapid improvement in cooling capacity is required, the backup cooling module 4 is activated, cooling medium is introduced into the cooling plate 41, and the drive gear on the motor shaft of the drive motor 33 drives the rack 322 to slide on the connecting ring 21, causing the connector 32 to move away and no longer press against the connector seat 42 of the cooling plate 41. The connector seat 42 is reset under the elastic force of the elastic element on the back, and the cooling plate 41 contacts the laser cutting head 1. During this process, the second cooling tube body 31 and the first cooling tube body 22 are connected through the first insertion gap 221 and the second insertion gap 311, which increases the cooling tube density and cooling capacity of the laser cutting head 1 at the first cooling tube body 22, and effectively improves the overall cooling capacity of the cooling system. This solves the problem that the existing laser cutting machine cooling system cannot quickly adjust the cooling capacity when cooling the laser cutting head, and effectively copes with the emergency situation where the laser cutting head temperature rises rapidly and remains at a high temperature without dropping.

[0047] Conversely, when the cooling system switches from emergency to normal state, the drive motor 33 drives the rack 322 to rotate in the opposite direction, causing the connector 32 to press the arc surface of the connector seat 42 through the guide slope 321, which again moves the connector seat 42 and the cooling plate 41 away from the laser cutting head 1, and the elastic element on the back of the connector seat 42 is compressed. Example 2

[0048] This embodiment further improves upon the above embodiment by providing the following technical solution: the cooler housing 5 is detachably mounted on the laser cutting head 1. Specifically, the cooler housing 5 is threaded onto the laser cutting head 1, and the surface of the cooler housing 5 is provided with several circumferentially arranged ribs 51.

[0049] To facilitate the maintenance of the main cooling module 2, auxiliary cooling module 3, and backup cooling module 4, the cooler housing 5 adopts a detachable design, such as adhesive bonding or threaded connection. To facilitate repeated disassembly and assembly of the cooler housing 5, the cooler housing is preferably fixed to the laser cutting head 1 by a threaded connection, and the surface ribs 51 facilitate rotation. Example 3

[0050] This embodiment further improves upon the above embodiment by providing the following technical solution: an arc-shaped retaining edge 213 is provided on the outer edge of the connecting ring 21, and the rack 322 contacts the inner wall of the arc-shaped retaining edge 213. Furthermore, a plurality of parallel positioning posts 214 are provided on the surface of the connecting ring 21, and the plurality of positioning posts 214 are arranged along the length direction of the rack 322.

[0051] The rack 322 on the connecting ring 21 is guided by the positioning post 214 and the arc-shaped stop 213 on the inner and outer sides, respectively, which effectively restricts the movement direction of the rack 322.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
