The working process of the multi-bending stamping die of the embodiment is briefly described as follows:
the material belt 1 enters from a channel between the lower template 34 and the pressing plate 36, when the third terminal 23 moves to the position below the first upper forming block 411, the mold assembly is performed, the first upper forming block 411 moves downwards, the bottom plate 35 is attached to the lower template 34, the lower forming block is pushed upwards, the top end of the first lower forming block 421 contacts the material belt 1, the corresponding third terminal 23 in the material belt 1 is located above the first lower forming block 421 and abuts against the inclined surface 52, and the angle of the abutting inclined surface is 45 degrees. The first upper forming block 411 presses the third terminal 23 downwards, and step 1 is executed by the cooperation of the pressing inclined plane 51 of the first upper forming block 411 and the pressing inclined plane 52 of the first lower forming block 421, that is, the third terminal 23 is bent to 45 °. And when punching and bending, the positioning needle 102 extends into the positioning hole 101 of the material belt 1 for positioning.
After bending is finished, the die is separated, the top plate 31, the backing plate 32 and the upper die plate 33 move upwards, and the positioning pins 102 are withdrawn from the positioning holes 101. The bottom plate 35 moves downwards, the lower forming block moves downwards, the material belt 1 is not in contact with the lower forming block, and the material belt 1 can move.
Next, when the 45 ° bent third terminal 23 in step 1 is moved to the lower side of the second upper molding block 412, the mold is closed again, the 45 ° bent third terminal 23 is bent to 90 °, and then the mold is separated. This process is similar to the process described above.
When the third terminal 23, which is originally 90 °, moves above the first push-down block 621, the mold is closed. The first push-up block 611 moves downwards, the first push-down block 621 moves upwards, and when the push-up inclined surface 81 at the lower end of the first push-up block 611 contacts the sliding inclined surface 82 of the first push-down block 621, the first push-up block 611 pushes the first push-down block 621 to approach the terminal which is bent by 90 degrees, so that the molding groove 6211 is positioned at the side of the terminal bent by 90 degrees. At the same time, the first upper molding block 711 moves downward to push the first lower molding block 721 toward the molding groove 6211, and the first lower molding block 721 pushes the 90 ° bent terminal into the molding groove 6211 to be bent, thereby forming a 135 ° bent terminal.
