[0021] In the following, embodiments of the stamping and forming device for the lithium battery protective top cover of the present utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-4 The stamping and forming device for the lithium battery protective top cover showing an embodiment of the present utility model includes a frame 1. Two stop rods 8 and limit rods 9 are fixedly connected to the top of the frame 1. A plurality of sheet materials are stacked between the stop rod 8 and the limit rod 9. The bottom of the stop rod 8 is provided with a discharge port adapted to the sheet material. A press 2 is fixedly installed on the right side of the top of the frame 1. A slidable slide plate 3 is arranged in the inner cavity of the frame 1. A plurality of sheet feeding assemblies 4 are arranged on the top of the slide plate 3. The sheet feeding assembly 4 includes a fixed frame 41 located on the top of the slide plate 3. Rectangular grooves 42 are respectively opened on the front side and the rear side of the top of the fixed frame 41. A pusher block 43 is rotatably connected to the inner cavity of the rectangular groove 42. A plurality of rectangular chutes 44 adapted to the pusher block 43 are opened on the top of the frame 1. Rotating columns 45 are fixedly connected to the front side and the rear side of the pusher block 43 respectively. The rotating columns 45 are rotatably connected to the fixed frame 41. A torsion spring 46 is sleeved on one side of the surface of the rotating column 45. One end of the torsion spring 46 is welded to the pusher block 43, and the other end of the torsion spring 46 is welded to the inner wall of the rectangular groove 42. Through the cooperation of the rotating column 45 and the torsion spring 46, an elastic torsion effect is exerted on the pusher block 43, so that the pusher block 43 can actively rotate and reset, thereby realizing the continuous feeding of the sheet material. A plurality of bolts 10 are respectively arranged through the front side and the rear side of the top of the fixed frame 41. The bolts 10 penetrate to the bottom of the fixed frame 41 and are threadedly connected to the slide plate 3. Through the cooperation of the bolts 10 and the threaded grooves, the distance between a plurality of fixed frames 41 is adjusted, so as to adapt to sheet materials of different widths, thereby expanding the processing range of the stamping device. Threaded grooves adapted to the bolts 10 are opened on the top of the slide plate 3. A stepper motor 5 is fixedly installed on the left side of the frame 1. The right side of the inner cavity of the frame 1 is rotatably connected to a threaded push rod 6 through a bearing. The left end of the threaded push rod 6 penetrates to the left side of the frame 1 and is fixedly connected to the output shaft of the stepper motor 5. A threaded seat 7 is fixedly connected to the bottom of the slide plate 3. The threaded seat 7 is threadedly connected to the surface of the threaded push rod 6.

[0023] Working principle: When the utility model is in use, the user stacks the sheet material raw materials between the baffle rod 8 and the limiting rod 9. Then the user starts the stepping motor 5, and the stepping motor 5 drives the screw propelling rod 6 to rotate intermittently forward and backward. With the cooperation of the screw seat 7, the sliding plate 3 reciprocates left and right in the inner cavity of the frame 1. The sliding plate 3 drives the fixed frame 41 to reciprocate. When the fixed frame 41 slides to the left, the dial block 43 rotates under the block of the sheet material raw materials and compresses the torsion spring 46. After the dial block 43 slides to the left side of the sheet material raw materials, the torsion spring 46 rebounds and drives the dial block 43 to reset. Then the sliding plate 3 slides to the right, and the sheet material raw materials slide to the right through the dial block 43, and the sheet material raw materials can be continuously pushed forward. After the sheet material raw materials reach the processing area of the stamping machine 2, the stamping machine 2 starts to stamp and form the sheet material raw materials.

[0024] To sum up: For this stamping and forming device for the protective top cover of the lithium battery, through the cooperation of the stepping motor 5, the screw propelling rod 6 and the screw seat 7, the sliding plate 3 is reciprocally pushed. With the cooperation of the material feeding component 4, the sheet material raw materials are continuously pushed forward. Finally, the stamping machine 2 stamps and forms the sheet material raw materials, so as to achieve the purposes of continuous feeding and high processing efficiency.
