Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a shell forming device for battery manufacturing. Background Technique

[0002] Battery shell forming is an important link in the battery manufacturing process, which refers to processing metal materials into battery shells with specific shapes through forming processes. Stamping is one of the most commonly used battery shell forming methods. Currently, the forming equipment usually places metal materials in a mold, and then uses the equipment to apply pressure to make the metal materials deform in the mold, so as to obtain the required shell shape.

[0003] When the current equipment is extruding, it is not convenient to make the raw iron sheet fully fit with the mold block, which results in the formed battery shell not being flat enough. It is also not convenient to stabilize the battery shell, which leads to the subsequent inability to weld the battery shell well. Content of the Utility Model

[0004] In order to overcome the above-mentioned drawbacks, the utility model provides a shell forming device for battery manufacturing, which can make the raw iron sheet fully fit with the mold block, so that the battery shell is flatter, and can stabilize the battery shell, so as to better weld the battery shell.

[0005] Technical Solution: A shell forming device for battery manufacturing includes a base, a support frame is fixedly connected to the base, a mold block is fixedly connected to the support frame, an electric push rod is fixedly connected to the base, fixing plates are fixedly connected to both telescopic rods of the electric push rod, sliding frames are slidably connected to both fixing plates, two tension springs are connected between the sliding frames and the fixing plates, electric heating rollers are rotatably connected to one side of both sliding frames close to each other, and a raw iron sheet is placed between the two fixing plates and the two electric heating rollers.

[0006] In addition, particularly preferably, the electric heating roller has a heating function.

[0007] In addition, particularly preferably, it further includes moving slide rails, the two moving slide rails are respectively fixedly connected to one side of the two fixing plates, two guide rails are fixedly connected to one side of the support frame close to the moving slide rails, slide rods are slidably connected between the moving slide rails and the adjacent guide rails, pressing plates are fixedly connected to one ends of the two slide rods away from the moving slide rails, and both pressing plates are in contact with the mold block.

[0008] In addition, particularly preferably, the pressing plate is made of rubber material.

[0009] Beneficial effects: 1. In the present utility model, the telescopic rod of the electric push rod extends to push the fixed plate, the sliding frame, the electric heating roller and the raw material iron sheet to move upward together. When the electric heating roller moves upward, it will first drive the raw material iron sheet to contact the mold block, and then when the electric heating roller continues to move, the raw material iron sheet will be deformed. The electric heating roller will move along the curved surface of the deformed raw material iron sheet, so that the electric heating roller squeezes the raw material iron sheet in the direction of approaching each other, making the raw material iron sheet fit well with the mold block, and further enabling the raw material iron sheet to be better formed into a battery case.

[0010] 2. When the fixed plate moves upward, it will drive the moving slide rail to move upward. When the moving slide rail moves upward, it will squeeze the sliding rod to move obliquely upward through the guide rail. When the sliding rod moves obliquely upward, it will drive the pressing plate to move obliquely upward. When the fixed plate resets, it will drive the moving slide rail to reset. When the moving slide rail resets, it will drive the sliding rod and the pressing plate to reset. When the pressing plate resets, it will squeeze the formed battery case on the mold block, making the battery case more stable, and thus better welding the battery case.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] Embodiment 1: A housing forming device for battery manufacturing, as Figures 1-5 shown, includes a base 1, a support frame 2 is welded on the base 1, a mold block 3 is welded on the support frame 2, an electric push rod 4 is connected to the base 1 by bolts, fixing plates 5 are connected to both telescopic rods of the electric push rod 4 by bolts, the two fixing plates 5 are symmetrically arranged, sliding frames 6 are slidably connected to both fixing plates 5, two tension springs 7 are connected between the sliding frames 6 and the fixing plates 5, heating rollers 8 are rotatably connected to one side of the two sliding frames 6 close to each other, the two heating rollers 8 are symmetrically arranged, a raw material iron sheet 9 is placed between the two fixing plates 5 and the two heating rollers 8, and the heating rollers 8 are used to heat and press the raw material iron sheet 9.

[0020] First, the staff places the raw material iron sheet 9 between the two fixing plates 5 and the two heating rollers 8, and then starts the electric push rod 4. The telescopic rod of the electric push rod 4 extends to push the fixing plates 5, the sliding frames 6, the heating rollers 8 and the raw material iron sheet 9 to move upward together. When the heating rollers 8 move upward, they will first drive the raw material iron sheet 9 to contact the mold block 3, and then when the heating rollers 8 continue to move, the raw material iron sheet 9 will be deformed. The heating rollers 8 will move along the curved surface of the deformed raw material iron sheet 9, and the tension springs 7 are stretched, so that the heating rollers 8 squeeze the raw material iron sheet 9 in the direction of approaching each other, making the raw material iron sheet 9 fit well with the mold block 3, and thus enabling the raw material iron sheet 9 to be better formed into a battery housing. When the telescopic rod of the electric push rod 4 contracts, it will drive the fixing plates 5, the sliding frames 6 and the heating rollers 8 to reset downward. Subsequently, the staff welds the battery housing, and then extracts the welded battery housing from the mold block 3.

[0021] Embodiment 2: On the basis of Embodiment 1, as Figures 5-6As shown in the figure, it further includes a moving slide rail 10. Two of the moving slide rails 10 are respectively welded to one side of the two fixing plates 5. Two guiding rails 11 are welded to the side of the support frame 2 close to the moving slide rail 10. The two guiding rails 11 are symmetrically arranged. A slide bar 12 is slidably connected between the moving slide rail 10 and the adjacent guiding rail 11. The moving slide rail 10 is used to push the slide bar. One ends of the two slide bars 12 away from the moving slide rail 10 are both connected with a pressing plate 13 by rivets. The pressing plate 13 is used to press the raw material iron sheet 9. Both of the pressing plates 13 are in contact with the die block 3.

[0022] When the fixing plate 5 moves upward, it will drive the moving slide rail 10 to move upward. The upward movement of the moving slide rail 10 will squeeze the slide bar 12 to move obliquely upward through the guiding rail 11. The oblique upward movement of the slide bar 12 will drive the pressing plate 13 to move obliquely upward. After the raw material iron sheet 9 is formed, the reset of the fixing plate 5 will drive the moving slide rail 10 to reset. The reset of the moving slide rail 10 will drive the slide bar 12 and the pressing plate 13 to reset. The reset of the pressing plate 13 will press the formed battery case on the die block 3, thereby making the battery case more stable and thus better welding the battery case.
