A plurality of one-way through holes 23 are provided on the shell body 1. A one-way valve needs to be set in the one-way through hole 23, and the flow direction is from the inside of the shell body 1 to the outside of the shell body 1; the outside of the shell body 1 is slidably connected with a float 11, and the float 11 slides vertically on the outer surface of the shell body 1 through a connecting piece. The float 11 moves upward after being subjected to a certain buoyancy, and a blocking component is provided on the float 11. The blocking component includes a connecting strip 31 fixedly connected to the float 11, and a blocking plate 32 is fixedly connected to the connecting strip 31. The blocking plate 32 is slidably connected to the shell body 1, and the blocking plate 32 slides vertically on the outside of the shell body 1 through a connecting piece to ensure that the blocking plate 32 moves upward to block the vent hole on the shell body 1; the shell body 1 is fixedly connected to the mounting plate 13 through a plurality of elastic columns 12, and the elastic columns 12 have a certain elasticity, which can reduce the impact of the battery inside the shell body 1 when the vehicle shakes.

By arranging the truncation components on the punching head 42, the need for The cutting step is performed first; during stamping, the punching head 42 drives the roller 46 and the cutting component to move downward, and the roller 46 is used to fix multiple positions of the aluminum plate. After the cutting component cuts off the excess part of the aluminum plate, the unlocking component triggers the movement of multiple limit components to unlock the cross bar 45, so that the roller 46 limits the aluminum plate moved by the stamping. When the cutting component is not in contact with the aluminum plate, the roller 46 cannot rotate at the fixed position of the limit component. At this time, the aluminum plate abutted by the roller 46 will not be able to move, so as to ensure that the cutting component moves downward to cut off the excess part of the aluminum plate. After the cutting component is cut, the movement of the cutting component drives the limit component to move and release the fixation with the roller 46. At this time, when the punching head 42 moves downward to stamp the cut plate, the plate movement drives the roller 46 to roll. At this time, the rolling roller 46 can limit the aluminum plate. The device can adjust the contact state between the roller 46 and the aluminum plate according to the specific processing conditions to improve the efficiency of stamping the aluminum plate into the shell body 1.

[0045] In an embodiment further provided by the present invention, the cutting assembly includes a rotating plate 61 rotatably connected to the punch head 42, and the bottom end of the rotating plate 61 is rotatably connected to a cutting knife 62; a guide plate 63 is fixedly connected to the punching table 41, and a guide unit for guiding the movement of the cutting knife 62 is provided on the guide plate 63. The cutting assembly can be provided with multiple groups, and two vertical cutting knives 62 are distributed up and down, so as to cut the aluminum plate into an open rectangular state of the unfolded view. The specific setting shape can be referred to the attached manual. Figure 5 The movement direction of the cutting knife 62 can be controlled by setting a guiding unit.

[0046] Furthermore, the guide unit includes a track groove 71 opened on the guide plate 63, and the cutting knife 62 is fixedly connected to a guide rod 72, and the guide rod 72 is slidably connected in the track groove 71. The track groove 71 is composed of a vertical groove and a horizontal groove, and is specifically L-shaped. When the roller 46 contacts the aluminum plate, the guide rod 72 moves in the vertical groove in the track groove 71 until the first elastic telescopic rod 43 is compressed to a certain extent. When the abutment force generated by the compression of the first elastic telescopic rod 43 is greater than the friction force between the roller 46 and the aluminum plate, the guide rod 72 moves to the bottom end of the vertical groove part of the track groove 71 and is about to enter the horizontal groove of the track groove 71. At this time, the cutting knife 62 completes the cutting and moves horizontally.

[0047] In an embodiment further provided by the present invention, the unlocking assembly includes a side plate 81 fixedly connected thereto, and a movable plate 83 is connected to the side plate 81 through a second elastic telescopic rod 82; the movable plate 83 is slidably connected to the cutting knife 62, and a trigger rod 84 is fixedly connected to the movable plate 83, and the trigger rod 84 contacts the top plate 54 during its movement, wherein the elastic coefficient of the second elastic telescopic rod 82 is greater than the elastic coefficient of the abutment spring 57, so when the trigger rod 84 contacts the top plate 54 and drives the top plate 54 to move laterally, the abutment spring 57 arranged on the top plate 54 is stretched first, and the movement of the top plate 54 drives the limiting rod 53 to separate from the limiting hole 56 on the fixed disk 55 until one side of the top plate 54 contacts one side of the limiting frame 44, at which time the blocking resistance of the top plate 54 by the limiting frame 44 increases, and at this time the trigger rod 84 stops synchronously, while the cutting knife 62 continues to move, and the second elastic telescopic rod 82 connected between the movable plate 83 and the side plate 81 is stretched.

[0048] In the embodiment provided by the present invention, a mold frame 91 is fixedly connected to the stamping table 41, and a stripper plate 92 is slidably connected to the mold frame 91. The stripper plate 92 is driven to move by the transmission assembly during the up and down movement of the stamping head 42. Before stamping, the top of the stripper plate 92 is on the same plane as the processing table, which is convenient for placing and cutting the aluminum plate. After the cutting is completed, the stripper plate 92 moves downward under the action of the transmission assembly as the stamping head 42 moves downward, so that the cut aluminum plate is stamped into the shape of the shell body 1. When the stamping is completed, the stripper plate 92 moves up again under the action of the transmission assembly so as to separate the stamped shell body 1 from the mold frame 91.

[0049] Specifically, the transmission assembly includes a support column 101 fixedly connected to the bottom of the stripping plate 92, the bottom end of the mold frame 91 needs to be provided with a groove for the support column 101 to slide, and the bottom end of the support column 101 is fixedly connected to an extension plate 102; a first side rod 103 is fixedly connected to the extension rod, a first contact plate 104 is fixedly connected to the first side rod 103, a second side rod 105 is fixedly connected to the first contact plate 104, a second side rod 105 is fixedly connected to the first contact plate 106, and the top cover of the punching head 42 is arranged between the first contact plate 104 and the second contact plate 106.

[0050] Furthermore, a clamping block 111 is fixedly connected to the guide plate 63, and a clamping unit for fixing the second contact plate 106 is provided in the clamping block 111; the clamping unit includes a third elastic telescopic rod 112 fixedly connected to the clamping block 111, one end of the third elastic telescopic rod 112 is fixedly connected to a contact ball 113, a fixing rod 114 is fixedly connected to the second contact plate 106, and a positioning ball 115 is fixedly connected to the fixing rod 114. When the punching head 42 completes the punching, it will drive the second contact plate 106 to move up synchronously until the positioning ball 115 on the second contact plate 106 enters into the clamping block 111, and the bottom of the positioning ball 115 is supported by the contact ball 113 on the third elastic telescopic rod 112.

[0051] In the solution further provided by the present invention, a support seat 121 is fixedly connected to one side of the stamping table 41, and an aluminum plate roller 122 is installed on the support seat 121. The support seat 121 is provided to facilitate the installation of the aluminum plate roller 122, and the aluminum plate roller 122 is the feeding system of the entire stamping table 41.

[0052] Working principle: When the shell body 1 is manufactured, the aluminum plate roller 122 discharges the material. After the aluminum plate moves to the punching table 41, the punching head 42 is driven downward by starting the external driving source. The punching head 42 moves downward and drives the limit frame 44 and the roller 46 in the limit frame 44 to move downward through the first elastic telescopic rod 43, and the aluminum plate on the punching table 41 is mortgaged and fixed. When the roller 46 contacts the aluminum plate, the punching head 42 continues to move downward. At this time, the first elastic telescopic rod 43 will be compressed, and when the punching head 42 moves downward, it will drive the cutting knife 62 to move downward synchronously through the rotating plate 61, and the cutting knife 62 will be affected by the track groove 71 when it moves downward, until the first elastic telescopic rod 43 is compressed to a certain amount, the cutting knife 62 will contact the aluminum plate on the punching table 41 and cut it. After completion, the cutting knife 62 will move laterally under the action of the track groove 71 and the guide rod 72 until the rotating plate 61 connected to the cutting knife 62 and the punch head 42 rotates, and while the cutting knife 62 moves laterally, the trigger rod 84 connected to the moving plate 83 of the cutting knife 62 will contact the top plate 54 and drive the top plate 54 to move to the side away from the roller 46. The movement of the top plate 54 drives the limiting rod 53 to disengage from the fixed plate 55 until the top plate 54 moves and contacts one side of the fixed frame 51. At this time, the top plate 54 and the trigger rod 84 are restricted by the fixed frame 51 and no longer move, and the cutting knife 62 continues to move when the punch head 42 moves downward. At this time, the second elastic telescopic rod 82 connected to the moving plate 83 and the side plate 81 of the cutting knife 62 is stretched;

[0053] When the second elastic telescopic rod 82 is stretched, the punch head 42 will contact the first contact plate 104 and drive the first contact plate 104 to move downward synchronously. After the first contact plate 104 is pushed downward, it will drive the positioning ball 115 on the second contact plate 106 to disengage from the two abutting balls 113 in the clamping block 111. At this time, the first contact plate 104 moves downward due to gravity, and drives the extension plate 102 to move synchronously through the first side rod 103. The extension plate 102 moves through the support column 101 to drive the stripping plate 92 to retract into the mold frame 91. At this time, the punch head 42 will slowly abut the cut aluminum plate and enter the mold frame 91, and finally punch out a complete shell body 1.

[0054] After the stamping is completed, the external driving source drives the punching head 42 to move upward. The upward movement of the punching head 42 will first drive the laterally moving cutting knife 62 to reset through the rotating plate 61. During the resetting of the cutting knife 62, the second elastic telescopic rod 82 first restores the force, and then slowly drives the unlocking rod to reset. The resetting of the unlocking rod releases the thrust on the top plate 54, and the compressed abutment spring 57 restores the force, driving the top plate 54 to reset. The resetting of the top plate 54 drives the limit rod 53 to be clamped in the limit hole 56 on the fixed plate 55, until the cutting knife 62 is reset to the vertical upward position, the punching head 42 contacts with the second contact plate 106, and drives the second contact plate 106 to move upward, and the second contact plate 106 moves upward through the second side rod 105 and the first contact The plate 104, the first side rod 103, the extension plate 102 and the support column 101 drive the stripping plate 92 to move upward, so that the shell body 1 stamped and formed in the mold frame 91 can be ejected, which is convenient for the mold frame 91 to unload. At this time, the punching head 42 continues to move upward, and the compressed first elastic telescopic rod 43 recovers to drive the limit frame 44 and the roller 46 to separate from the punching table 41, until the positioning ball 115 on the second contact plate 106 enters the clamping block 111 again, and abuts against the two abutting balls 113 in the clamping block 111 to move away. When the positioning ball 115 moves upward and separates from the abutting ball 113, the abutting ball 113 is reset under the action of the third elastic telescopic rod 112 and abuts against the fixing rod 114 at the bottom of the positioning ball 115.
