The working principle of the double-station sheet stamping die in the embodiment is as follows:

alternately feeding materials in the upper fixed die 21 at the top of the stamping base 1 and the side stamping channel 13 at the side part of the stamping base 1, wherein when a thin plate enters the side stamping channel 13, the first air pump 41 generates negative pressure in the cavity of the side fixed die 31, so that the thin plate is close to the cavity of the side fixed die 31, and meanwhile, the electromagnet 33 in the side fixed die 31 is electrified, so that the thin plate is accurately positioned in the cavity of the side fixed die 31; meanwhile, in the punching process, the punching motor 7 rotates, in the one-time circumferential rotation process of the rotating disc 8, the abutting surface 81 of the rotating disc 8 respectively pushes the first punching column 51 and the second punching column 52 to reciprocate downwards once, in the downward movement process of the first punching column 51, the first punching column 51 drives the upper movable die 22 to move downwards, the upper movable die 22 punches the thin plate in the upper fixed die 21, meanwhile, the second punching column 52 moves upwards under the action of the second spring 523, the transmission rack 524 on the second punching column 52 drives the second gear 62 to rotate clockwise, because the first gear 61 and the second gear 62 are coaxially arranged, in the rotation process of the second gear 62, the first gear 61 also synchronously rotates clockwise, the first gear 61 drives the punching rack 35 to move towards the outer direction of the punching base 1, the side movable die 32 is far away from the side fixed die 31, the electromagnet 33 in the side fixed die 31 is de-energized, meanwhile, the first air pump 41 blows air, the sheet punched last time in the side fixed die 31 falls into the blanking channel 15 for discharging, and then the side punching channel 13 waits for feeding of the next sheet to be punched again; during the process that the rotating disc 8 pushes the second stamping column 52 to move downwards, the transmission rack 524 on the second stamping column 52 drives the second gear 62 to rotate anticlockwise, so that the first gear 61 drives the stamping rack 35 to slide towards the side stamping channel 13, the side movable die 32 and the side fixed die 31 are matched, the sheet stamping process in the side stamping channel 13 is completed, meanwhile, during the process that the first stamping column 51 moves upwards, the upper movable die 22 leaves the upper fixed die 21, the second air pump 42 blows air, the sheet stamped in the upper fixed die 21 is blown up to leave the cavity of the upper fixed die 21, and the discharging is completed.

In the double-station sheet stamping process, the first stamping column 51 and the second stamping column 52 synchronously move in a coordinated manner, and the second stamping column 52 synchronously moves upwards while the first stamping column 51 moves downwards, so that in the process of stamping the sheet in the fixed die 21 on the stamping base 1, the sheet stamped in the fixed die 31 at the side part of the stamping base 1 is unloaded simultaneously; the second punching column 52 moves downwards and simultaneously the first punching column 51 moves upwards synchronously, so that the thin plate punched last time in the fixed mold 21 on the punching base 1 is synchronously unloaded while the thin plate in the fixed mold 31 on the punching base 1 is punched. Therefore, the invention fully utilizes the unloading time in the stamping process, so that the sheet can be stamped while the sheet is unloaded, and the stamping efficiency of the sheet is improved.

In conclusion, the stamping base 1 is provided with the two stamping stations at the top and the side respectively, so that the sheet stamping die provided by the invention has the two stamping stations, the continuous stamping of the sheet at the two stations is realized, and the stamping efficiency is improved.
