Background technique

With the popularization of electric vehicles, the power battery is the power source of hybrid electric vehicles and pure electric vehicles. The power battery usually includes a power battery casing and a power battery module composed of multiple single batteries and accommodated in the power battery casing. The battery casing is used to protect the power battery module, for example, to avoid damage to the power battery module when the vehicle collides, so the demand for the power battery casing is getting higher and higher. The existing technology is produced by the traditional stamping process. First, the material The belt is stamped out of the disc, and then the disc is stretched and stamped. The stamping process of the transmission is processed in one process and then processed in another process. However, this traditional stamping process has low production efficiency and requires a lot of labor. Many, the production cost is high, and in order to improve production efficiency, all the processing procedures of the power battery casing need to be set up on one assembly line, and the stamping and stretching process is directly performed on the wafer. Traditionally, the material belt is used for processing. The side can be positioned, and now the wafer is used for processing, and the transmission processing equipment is suitable, so a mold that can be used for positioning, stamping, stretching and processing of the wafer is now needed.

Further, the vertical section of the wedge is trapezoidal.

Further, the left end of the oblique wedge is provided with a guide groove, and the connecting rod is provided with a slider matching the guide groove, and the connecting rod is connected with the guide groove on the oblique wedge through the slider.

The beneficial effects of the utility model are:

The utility model is the first stamping and stretching process of the disk raw material on the power battery shell flow production line. A sinking-shaped concave mold is arranged in the lower mold fixing seat, so that the disk joint can be placed on the sinking-shaped concave mold. Fast positioning, and the forming cushion block that slides up and down is set in the die, and the wedge ejecting device is also provided on the lower die, and the wedge ejecting device also includes a wedge that can drive the forming cushion to slide up and down, connecting Rod and cylinder, the cylinder is connected with the wedge through the connecting rod, the cylinder can drive the wedge to move left and right, so as to drive the wedge to drive the forming pad to move up and down; when working, first place the disc on the sunken table-shaped concave through the manipulator Inside the mold, then the upper mold moves downwards, first the edge holder presses the peripheral edge of the disc, then the stretching punch continues to move downwards, and with the cooperation of the forming pad, it drives the disc to stretch downwards, stretching After the completion; the upper mold is reset, and the wedge ejecting device starts to move at this time, and the cylinder drives the wedge to move to the right, so that the wedge drives the forming pad upward to eject the stretched disc, and the manipulator takes out the ejected molding material , The inclined wedge ejecting device is reset, and the above actions are repeated, which shows that the utility model can quickly position the disc material, and has the advantages of high production efficiency and low production cost.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

The first stamping die on the production process of a power battery case shown in Figures 1 to 4 includes an upper die 1 and a lower die 2, and the upper die 1 includes an upper die holder 11 for pressing the disc The edge holder 12 and the cylindrical drawing punch 13 for stretching the disc, the holder 12 can slide up and down in the upper die holder 11, and the upper end of the drawing punch 13 is fixed On the upper mold holder 11, the lower end is arranged in the blank holder 12, the lower mold 2 includes a lower mold holder 21, and the lower mold holder 21 is provided with a sunken platform-shaped concave mold 22. The mold 22 is provided with a forming pad 23 that slides up and down, and the lower mold 2 also includes a wedge ejector device, which includes a wedge 31 that can drive the forming pad to slide up and down, a connecting rod 32 and Cylinder 33, the cylinder 33 is connected with the wedge 31 through the connecting rod 32, the cylinder 33 can drive the wedge 31 to move left and right, and the wedge 31 can drive the forming pad 23 to move up and down.

In this embodiment, the vertical section of the wedge 31 is trapezoidal.
