The invention belongs to the technical field of dies, and particularly relates to a
metal punching die. The
metal punching die comprises a bottom plate, a lower die, an upper die, guide sleeves, connecting strips, a mounting plate, a first mounting hole, second mounting holes, a fixing sleeve, an
electromagnet, a guide ring, a push block, a movable iron rod, a first spring, a material guide
pipe,a second spring, a connecting
pipe, a three-way
pipe, a dust suction box, a side plate, a first
rubber ring, a first filter screen, a
handle, a circular ring, a
discharge hole, guide rods, a punchingcavity,
metal blocks, third springs, a pressing plate, a
punching rod, a mounting frame, a centrifugal
impeller, a motor, a baffle ring, a frame, a second
rubber ring, a second filter screen and gas springs. The metal block punching device is reasonable in structure and suitable for punching and removing excess material on one side of the metal block; and during punching, the punching rod is in contact with the metal block, and the pressing plate and the multiple third springs are arranged, so that the pressing limit of the metal block can be carried out in advance, the stability of the metalblock during punching is improved, movement and upwarping are avoided, and the punching precision is improved.
