In the present embodiment, the mounting base 100 is used to connect the compact punch pad positioning mechanism 10 to a lower die of a punch die. The positioning bracket 200 is used for connecting the positioning bracket 200 and the material supporting assembly 300 respectively, so that the material supporting assembly 300 can be stably arranged on a lower die of the stamping die. The material supporting assembly 300 is used for positioning and supporting a sheet material to be punched so as to ensure smooth punching processing. The reset mechanism 400 is used for providing a supporting force for the material supporting assembly 300, so that the material supporting assembly 300 has a power for lifting the sheet material, and meanwhile, the reset mechanism 400 is also used for resetting the material supporting assembly 300 after stamping each time, so that the material supporting assembly 300 can lift the sheet material again, and the stamping operation is continued.

Furthermore, a plurality of fixing through holes 120 are formed in the mounting base 100, the mounting base 100 comprises a plurality of threaded fasteners 100, when the compact punching press material supporting and positioning mechanism 10 is mounted, the fixing through holes 120 are aligned with threaded connecting holes in the lower die of a punching die, the threaded fasteners 100 penetrate through the fixing through holes 120 and are connected with the threaded connections, and therefore the mounting base 100 is stably arranged on the lower die of the punching die. The positioning bracket 200 is welded to the mounting base 100, so that the positioning bracket 200 is stably arranged on the mounting base 100. The material supporting assembly 300 comprises a material supporting swing arm 310 and a limiting rod 320, the material supporting swing arm 310 comprises a supporting part 311, a rotating part 312 and a resetting part 313 which are sequentially connected and integrally formed, and the supporting part 311 of the material supporting swing arm 310 is used for supporting a sheet material, so that the sheet material can be placed on a lower die in a balanced manner before stamping. Because the connecting portion of the material supporting swing arm 310 is rotatably connected to the positioning bracket 200, the material supporting swing arm 310 can rotate around the rotation center axis of the rotating portion 312, so that the lifting portion 311 can support the sheet material to be lifted and dropped in a reciprocating manner. Because the three are the integrated into one piece structure, the whole material supporting swing arm 310 has good strength and is not easy to damage during working. The reset portion 313 is used to connect with the reset mechanism 400, so that the lifting portion 311 of the material supporting swing part can be lifted again after falling. The limiting rod 320 is connected with the positioning support 200, the extending direction of the limiting rod 320 is parallel to the rotating central axis of the rotating part 312, and the limiting rod 320 is used for limiting the rotating stroke of the material supporting swing arm 310, so that the lifting part 311 of the material supporting swing arm 310 can be lifted quickly after falling, and the reset speed of the material supporting swing arm 310 is further improved. The reset mechanism 400 is used for lifting the lifted portion 311 after falling again, and comprises an iron block 410 and a magnet assembly 420, the magnet assembly 420 comprises a strip iron core 421 and an electromagnetic coil 422, the electromagnetic coil 422 is sleeved outside the strip iron core 421, the strip iron core 421 is connected with the positioning bracket 200, so that the magnet assembly 420 is stably arranged on the positioning bracket 200, the electromagnetic coil 422 is connected with an external circuit, the external circuit provides current for the electromagnetic coil 422, the magnet assembly 420 consisting of the energized electromagnetic coil 422 and the strip iron core 421 can generate a magnetic field, because the iron block 410 of the reset mechanism 400 is connected with the reset portion 313 of the material supporting swing arm 310, and the extending direction of the strip iron core 421 of the magnet assembly 420 is opposite to the iron block 410, the magnet assembly 420 can generate magnetic field force to the iron block 410, so that the iron block 410 is attracted by the magnet assembly 420, and the reset portion 313 of the material supporting swing arm 310 has a tendency of moving towards the magnet assembly 420, therefore, the lifting portion 311 can continuously and stably lift the sheet before the punching, and the reset portion 313 is reset by the magnetic force after the punching, so that the lifting portion 311 lifts the sheet again.

In the stamping process, the upper die of the stamping die is pressed downwards, the sheet is pressed to fall onto the lower die of the stamping die, meanwhile, the sheet drives the lifting part 311 to fall together, because the rotating part 312 of the material supporting swing arm 310 is rotatably connected with the positioning support 200, the falling of the lifting part 311 drives the material supporting swing arm 310 to rotate, the rotation of the material supporting swing arm 310 drives the resetting part 313 to lift, namely, the iron block 410 of the resetting part 313 moves towards the direction far away from the magnet assembly 420, when the lifting part 311 falls to the lowest position, the material supporting swing arm 310 just rotates to abut against the limiting rod 320, the limiting rod 320 can prevent the material supporting swing arm 310 from continuously rotating due to inertia, and the situation that the resetting part 313 excessively keeps away from the magnet assembly 420 is avoided, so that the material supporting swing arm 310 is reset conveniently. After the punching is completed, because the lifting part 311 is no longer subjected to the punching force of the upper die of the punching die, the reset part 313 moves towards the direction of the magnet assembly 420 under the action of the magnetic force, and then the material supporting swing arm 310 rotates again, and the lifting part 311 lifts and lifts the sheet again, namely, the reset of the material supporting swing arm 310 is completed.

Because the material supporting positioning mechanism of the application adopts the electromagnetic force to drive the material supporting swing arm 310 to reset, the resetting effect cannot be reduced along with the lapse of time, namely, the resetting stability is stronger, and meanwhile, the safety risk caused by resetting failure is also avoided, so that the reliability is higher.
