Description

Technical Field

[0001] The present invention relates to the technical field of stamping processing devices, and in particular to a power lithium battery shell processing device and a processing method thereof. Background Art

[0002] Stamping is a forming process in which a press and a die apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Automobile bodies, chassis, fuel tanks, radiators, boiler drums, power lithium battery housings, and silicon steel sheets for the iron cores of motors and electrical appliances are all processed by stamping.

The overall structure is more streamlined and effective, which reduces the cost of the entire stamping device and the difficulty of subsequent overhaul and maintenance, and improves the overall applicability of the device.

[0038] See also Figure 1-8 A power lithium battery shell processing device includes a base assembly 1, the base assembly 1 includes a bottom platform 11, a mold 12 is embedded and fixedly installed on the bottom platform 11, an unlocking groove 13 is opened on the bottom platform 11, and a discharge notch 14 is opened on the edge of the bottom platform 11;

[0039] In this embodiment, it should be noted that the base 11 is fixed on the ground, the mold 12 can be detached, the unlocking groove 13 is located at the downstream position of the rotation mode and is provided with a slope structure, and the discharge slot 14 is tilted toward the outside of the base 11. In this way, the stamping assembly 5 can be used to stamp the parts in the mold 12. The processed stamping parts are continuously moved between multiple molds 12 through the conveying assembly 7, and finally can automatically tilt and fall when reaching the position of the discharge slot 14 to realize the discharge of the processed parts.

[0040] See also Figure 1-3 A power lithium battery shell processing device includes a stamping assembly 5, which includes an air duct 51. An air duct hose 52 is fixedly installed at the bottom end of the air duct 51. A connecting pipe 53 is fixedly installed at the bottom end of the air duct hose 52. A stamping head 54 is fixedly installed at the bottom end of the connecting pipe 53. An air hole 55 is opened on the side of the stamping head 54.

[0041] In this embodiment, it should be noted that the air guide duct 51 is fixedly installed at the top of the seat block 4, one end of the air guide duct 51 is provided with a breathable mesh, and a negative pressure machine is provided at the position of the mesh, the air guide hose 52 is provided inside the seat block 4, and a limiting protrusion is provided at the top of the connecting pipe 53, which is located in the seat block 4 and is inserted into the limiting movable setting, and the connecting pipe 53 gradually decreases in length at each stamping position in the circular rotation direction, and the position corresponding to the minimum height of the punching head 54 is upstream in the rotation direction and is the feeding position of the raw material, the connecting ends of the air guide hose 52 and the connecting pipe 53 are sealed and connected, and the air hole 55 is located at the workpiece stamping position. The side surfaces at both ends of the same length are opened, so when the hydraulic rod 3 is used to drive the seat block 4 to move downward, the initial state of each air hole 55 is naturally drooping, so that multiple air holes 55 will contact the stamping part below one by one, until the shortest air hole 55 in the connecting tube 53 contacts the stamping part and continues to move downward, the stamping force will be applied, and the stamping force is transmitted from the seat block 4 to the connecting tube 53 and finally acts on the stamping head 54 for stamping, and the negative pressure suction force generated by the air guide duct 51 will adsorb the inner surface of the stamping part at the air hole 55, and then after completing the stamping at the current position, the internal stamping part will be adsorbed, lifted and taken out, which is convenient for subsequent transportation and re-stamping.

[0042] See also Figure 6-7 A power lithium battery shell processing device includes a barrier component 6, the barrier component 6 includes a sleeve ring 61, a coil spring 62 is installed inside the sleeve ring 61, and a separation rod 63 is installed outside the sleeve ring 61;

[0043] In this embodiment, it should be noted that the sleeve ring 61 limits the movable sleeve on the core rod 2 and limits its rotation range, so that the separation rod 63 is between the current unlocking groove 13 and the edge of the first mold 12 upstream of its rotation direction, and the two ends of the coil spring 62 are fixedly connected to the core rod 2 and the inside of the sleeve ring 61, respectively. The separation rod 63 is spaced apart from the upper surface of the conveying component 7. In this way, by utilizing the rotation of the conveying component 7 below, the workpiece on the conveying component 7 can first be blocked by the separation rod 63 during the rotation process and separated into the mold 12 at the corresponding position, and then continued rotation will drive the separation rod 63 to rotate, thereby realizing the separation from the stamping area after the separation rod 63 completes the part separation, ensuring that the subsequent stamping is carried out normally, and before the next stamping, the continued rotation of the conveying component 7 will release the separation rod 63, and use the elastic potential energy stored in the coil spring 62 to rebound to the edge of the mold 12 upstream of the rotation direction for the next blocking and separation.

[0044] See also Figure 6-9A power lithium battery casing processing device includes a conveying assembly 7, which includes a base ring 71. An extension plate 72 is fixedly mounted on the outer side of the base ring 71. A tray 73 is movably mounted on one end of the extension plate 72. A locking pin 74 is movably mounted on the tray 73. A roller 75 is movably mounted in the end of the locking pin 74. A driving gear 76 is meshed with the inner side of the base ring 71. A driving motor is provided at the bottom end of the driving gear 76.

[0045] The locking pin 74 is located at the corner upstream of the rotation direction of the tray 73 close to the extension plate 72, and the bottom end of the locking pin 74 can be inserted into the unlocking groove 13, and the roller 75 is arranged to fit the side of the separation rod 63. In this way, after the punching head 54 absorbs and lifts the internal stamping parts, the drive motor can be used to drive the drive gear 76 to rotate, thereby driving the base ring 71 and the tray 73 to rotate. During the lifting process, the stamping parts will be restricted by the stripping assembly 8 and peeled off from the punching head 54. In this way, the tray 73 can carry the stamping parts to rotate and move to the next stamping position, thereby ensuring the continuity of the entire stamping.

[0046] See also Figure 1-5 A power lithium battery shell processing device includes a stripping assembly 8, which includes a base 81. A pair of limiting side plates 82 and a vertical rod 83 are fixedly installed on the upper surface of the base 81. A telescopic hose 84 is fixedly installed on the base 81 between the two limiting side plates 82. A stripping plate 85 is movably sleeved on the vertical rod 83. A water tank 86 is fixedly installed on the base 81. A pressure block 87 is movably provided inside the water tank 86 for sealing.

The stripping plate 85 is spaced apart from the upper surface of the tray 73 and the distance between them is greater than the maximum groove depth of the mold 12 at the current stamping position. The through groove provided on the stripping plate 85 is adapted to the cross-sectional shape of the stamping head 54 corresponding to the current position. The telescopic hose 84 is connected to the inside of the water tank 86, and the telescopic hose 84 and The water tank 86 is filled with water, and the initial highest position corresponding to each stripping plate 85 is sleeved on the lower end of the corresponding punching head 54, so that downward pressure can be applied to the stripping plate 85 during the downward stamping process. This downward pressure will cause the telescopic hose 84 to contract, and then squeeze the water therein into the water tank 86, so that the pressure block 87 moves upward. After the stamping stage is completed, the weight of the pressure block 87 will press the water in the water tank 86 downward into the telescopic hose 84, and then the stripping plate 85 will return to its current highest position, which is convenient for stripping the stamped parts lifted out subsequently, thereby realizing continuous operation of the entire device.

[0048] A power lithium battery shell processing device, the specific steps of the processing method are as follows:

[0049] S1, placing the initial raw material embryo on the corresponding mold 12;

[0050] S2. Start the hydraulic rod 3 to drive the seat block 4 downward, thereby causing the stamping assembly 5 to move downward to perform the first step of stamping. After the stamping is completed, the punch head 54 is lifted, and at the same time, the negative pressure machine in the top air duct 51 generates negative pressure suction to lift the stamped part;

[0051] S3. Start the drive motor to drive the drive gear 76 to rotate, thereby driving the base ring 71 and the tray 73 to rotate, and rotate the tray 73 to the position where the mold 12 is located. At the same time, the hydraulic rod 3 is lifted. After the tray 73 rotates to the position of the mold 12, the top of the stamping part contacts the lower surface of the stripping plate 85, and the stamping part is stripped. After stripping, the stamping part falls to the upper surface of the tray 73;

[0052] S4, the tray 73 drives the stamped part after stripping to rotate to the next stamping position, and the separation rod 63 blocks and separates the stamped part so that it falls into the next corresponding mold 12. After completion, the tray 73 continues to rotate, thereby driving the separation rod 63 to rotate out of the stamping area, and the initial blank is continued to be placed at the initial position, and then the next stamping begins;

[0053] S5. When the stamped part is finally rotated and transported to the discharge slot 14 after multiple stampings, the tray 73 automatically rotates to discharge the finished product from the discharge slot 14, and subsequent rotations will cause the tray 73 to re-attach to the upper surface of the base 11.

After the stamping is completed, the stamping head (54) is lifted, and at the same time, the negative pressure machine in the top air guide pipe (51) generates negative pressure suction to lift the stamping part; S3, starting the driving motor to drive the driving gear (76) to rotate, thereby driving the base ring (71) and the tray (73) to rotate, rotating the tray (73) to the position of the mold (12), and at the same time, the hydraulic rod (3) is lifted so that the top of the stamping part contacts the lower surface of the stripping plate (85) after the tray (73) rotates to the position of the mold (12), thereby achieving the stripping of the stamping part, and the stamping part falls onto the upper surface of the tray (73) after the stripping; S4, the tray (73) drives the stamped part after stripping to rotate to the next stamping position, and the separation rod (63) blocks and separates the stamped part so that it falls into the next corresponding mold (12). After completion, the tray (73) continues to rotate to drive the separation rod (63) to rotate away from the stamping area, and the initial blank continues to be placed at the initial position, and then the next stamping begins; S5. When the stamped part is finally rotated and transported to the discharge slot (14) after multiple stampings, the tray (73) automatically rotates so that the finished product is discharged from the discharge slot (14), and subsequent rotations cause the tray (73) to reattach to the upper surface of the bottom platform (11).
