Description

Technical Field

[0001] The invention relates to the field of hollowing out plates, and in particular to a hollowing out device for a battery heat sink of a new energy vehicle. Background Art

[0002] New energy vehicle batteries are the core components of the vehicle, mainly including lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries and supercapacitors. Modern new energy vehicles mainly tend to use lithium-ion batteries and nickel-metal hydride batteries. These two types of batteries not only have high energy density, but also have environmental protection performance, which can fully meet the power needs of new energy vehicles.

[0003] The heat sink is an important component of the heat dissipation system of new energy vehicles. Its function is to evenly distribute the heat generated by the battery pack to the entire heat dissipation system to maintain a stable operating temperature of the battery pack. During production, the heat sink needs to be punched and hollowed out. Generally, a hole punching knife is used to punch holes in the plate. The hole punching knife needs to be pushed by a hydraulic telescopic rod so that the hole punching knife contacts the plate and cuts the plate into holes. Due to the thin thickness of the plate, the pressure of the hole punching knife will cause the opening of the plate to bend and extend downward, which is prone to uneven holes, affecting the later installation between the heat sink and the battery casing.

[0024] Example 4: Please refer to Figure 2 and Figure 8 , this embodiment further illustrates other embodiments. A discharge cavity is provided inside the operating table 1 in the figure for storing the waste materials processed by hollowing the plates. Two symmetrically distributed baffle plates 29 are fixedly installed on the inner side of the discharge cavity. Two symmetrically distributed cleaning ports are provided on the outer side of the operating table 1 to facilitate the staff to take out the waste materials. An elastic mesh plate 30 is fixedly installed on the inner side of the operating table 1. The elastic mesh plate 30 is in an arc structure. The elastic mesh plate 30 is located directly below the discharge port of the operating table 1 so that the waste materials can fall on the elastic mesh plate 30. The arc surface of the elastic mesh plate 30 enables the waste materials to slide into the cleaning ports. The elastic mesh plate 30 is located between the two cleaning ports. Two symmetrically distributed discharge grooves are provided on the bottom inner wall of the operating table 1. The inner side of the discharge groove is in an inclined surface structure to facilitate the sliding out of the waste materials. A driven rod 31 is rotatably installed on the inner side of the operating table 1. The driven rod 31 is located below the elastic mesh plate 30. Driven wheels 32 respectively cooperating with the two second toothed belts 20 are fixedly installed at both ends of the driven rod 31 so that the second toothed belt 20 can drive the driven wheel 32 to rotate, and the driven wheel 32 can drive the driven rod 31 to rotate. Two symmetrically distributed cams 33 are fixedly installed on the outer side of the driven rod 31. The outer side of the cam 33 is in contact with the bottom of the elastic mesh plate 30. When the driven rod 31 drives the cam 33 to rotate, the bottom of the elastic mesh plate 30 can be repeatedly knocked to facilitate the rapid discharge of the waste materials.

[0025] Working principle: First, the operator places the sheet on the operation table 1 and rotates the adjustment disk 24, causing the adjustment disk 24 to drive the corresponding adjustment rod 21 to rotate. The adjustment rod 21 drives the two corresponding third gears 22 to rotate synchronously, enabling the third gear 22 to cooperate with the two third gears 22 on another adjustment rod 21 to drive the second toothed belt 20 to make a rotational movement along the installation groove on the operation table 1. The two second toothed belts 20 drive the push plate 23 to move. The push plate 23 contacts the outer side of the sheet and pushes the sheet to move directly below the punching knife 4. The operator can then move the sheet to the corresponding position according to the position of the hollowing process. At this time, the operator starts the drive motor 12, causing the drive motor 12 to drive the corresponding first screw rod 8 to rotate. The first screw rod 8 drives the first toothed belt 11 to make a rotational movement through the first gear 9 at its end, enabling the first toothed belt 11 to drive another first gear 9 and the second gear 19 to rotate synchronously, thereby achieving the synchronous rotation of the two first screw rods 8. Moreover, the second gear 19 drives the second screw rod 15 to rotate. Among them, the first screw rod 8 drives the mounting bracket 6 to move along the inner side of the positioning plate 3 through the first moving block 7. The two mounting brackets 6 push the tool holder 5 downward, causing the tool holder 5 to drive the punching knife 4 to contact the top of the sheet, realizing the hollowing process of the sheet. At the same time, the second screw rod 15 drives the two mounting rods 17 to move along the inner side of the positioning plate 3 through the second moving block 16. The mounting rods 17 push the push block 18 downward. At this time, the punching knife 4 penetrates the sheet and inserts into the lower pressing frame 14. The waste material from the hollowed-out sheet enters the punching knife 4. During the downward movement of the push block 18, it contacts the waste material, ejects the waste material from the inside of the punching knife 4, and pushes it into the discharge cavity of the operation table 1, landing above the elastic mesh plate 30. Utilizing the arc surface of the elastic mesh plate 30, the waste material can slide into the discharge groove. As the punching knife 4 moves, the upper pressing frame 13 on the outside of the punching knife 4 contacts the top of the sheet. By the cooperation of the upper pressing frame 13 and the lower pressing frame 14, the punched hole of the sheet is flattened, solving the problem of the bending of the punched hole of the sheet. Moreover, the upper pressing frame 13 drives the support rod 25 to move along the inner side of the tool holder 5. Utilizing the elasticity of the spring 26, a buffer is provided for the upper pressing frame 13 to prevent excessive pressing force on the sheet. Finally, the drive motor 12 drives the corresponding first screw rod 8 to rotate in the reverse direction, retracts the punching knife 4, and completes a single punching, realizing the automatic discharge of waste material, thereby achieving the effects of automatic flattening and waste material treatment; After a single punching, the operator rotates the adjusting disk 24 again, so that the push plate 23 pushes the plate to move along the top of the operating table 1, moving the next punching point of the plate under the punching knife 4. At the same time, the second toothed belt 20 drives the third gear 22 to rotate, the third gear 22 drives the driven rod 31 to rotate, and the driven rod 31 drives the two cams 33 to rotate synchronously, causing the cams 33 to repeatedly strike the bottom of the elastic mesh plate 30, so that the waste on the elastic mesh plate 30 can be bounced into the discharge chute, preventing the accumulation of waste, improving the convenience of waste treatment. Thus, the operator can start the drive motor 12 again to punch the plate again, and cooperate with the operation of the adjusting disk 24 to complete the hollowing process of the plate, thereby achieving the effect of improving the convenience of hollowing processing.
