Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a stamping die convenient for discharging comprises a lower die plate 3, a lower cushion plate 4 and a lower die seat 5 which are sequentially arranged from top to bottom, wherein the lower die plate 3, the lower cushion plate 4 and the lower die seat 5 are respectively provided with corresponding bolt holes and are fixed by bolts, a blanking hole cavity 1 is formed between the lower die plate 3, the lower cushion plate 4 and the lower die seat 5, the blanking hole cavity 1 is cylindrical, the blanking hole cavity 1 comprises a blanking hole cavity 11 and a chip collecting hole cavity 12 from top to bottom, the blanking hole cavity 11 is arranged on the lower die plate 3, the chip collecting hole cavity 12 is arranged on the lower cushion plate 4 and the lower die seat 5, the lower cushion plate 4 and the lower die seat 5 are made of stainless steel materials, the service life is long, the bottom of the blanking hole cavity 1 is provided with an air supply device 2, the top end of the air supply device 2 is communicated with a first connecting pipe 9, the top of the first connecting pipe 9 is movably connected with a second connecting pipe 14 through a clamping ring 13, the second, the service life is long.

Wherein, air supply arrangement 2 includes iron box 10, the inner chamber of iron box 10 is equipped with motor 8, motor shaft 24 is being connected to motor 8, motor shaft 24 evenly lays fan post 21 all around, fan post 21 is cylindrical, what adopt is stainless steel material, long service life, it is not fragile, there is the bearing fan post 21 one side of keeping away from motor shaft 24, the inner chamber of bearing is pegged graft and is had the rotation axis, one side top of fan post 21 is provided with fan leaf ball 22, fan leaf ball 22 is globular, good stability has, one side top of fan leaf ball 22 is provided with fan leaf 23, fan leaf 23 is the fan leaf form, every fan post 21 top has all set up a fan leaf ball 22, iron box 10 is equipped with the through-hole, the through-hole can ventilate, can dispel the heat.

The blanking hole cavity 11 is conical, the minimum hole diameter of the blanking hole cavity 11 is smaller than the hole diameter of the scrap collecting hole cavity 12, and the maximum hole diameter of the blanking hole cavity 11 is equal to that of the scrap collecting hole cavity 12, so that fallen scraps in the blanking hole cavity 11 can vertically fall into the scrap collecting hole cavity 12, and the situation that the scraps are blocked due to the fact that the scrap collecting hole cavity 12 is too small or the scraps which are too large in the scrap collecting hole cavity 12 move in the scrap collecting hole cavity 12 is avoided.

The automatic blanking device comprises a male die 6, wherein the male die 6 is fixedly arranged below an upper clamping plate 7 through a bolt, the male die 6 is vertically arranged downwards, the male die 6 and a blanking hole cavity 1 are coaxially arranged, the outer diameter of a stamping end of the male die 6 is matched with the minimum hole diameter of a blanking hole cavity 11, the situation that subsequent blanking is influenced when scraps are clamped in the blanking hole cavity 11 is avoided, the scraps are continuously pushed downwards into a scrap collecting hole cavity 12 after the scraps are blanked from materials, and the situation that 'scrap jumping' of the scraps causes life safety to operators is prevented.

The connecting pipe II 14 is arranged at the bottom end of the blanking hole cavity 1, the connecting pipe II 14 is movably connected with the connecting pipe I9 through the clamping ring 13, the clamping ring 13 is cylindrical, the inner diameter of the clamping ring 13 is larger than the outer diameter of the connecting pipe I9, the connecting pipe II 14 is connected with the connecting pipe I9 through the clamping ring 13, the connecting pipe II 14 and the connecting pipe I9 are not prone to being separated and falling, stability is high, the connecting pipe II 14 and the connecting pipe I9 are made of stainless steel materials, and service life is long.

The working principle is as follows: when the scrap collecting device is used, the male die 6 punches downwards, and the punching end of the male die 6 pushes scraps into the scrap collecting hole cavity 12. The male die 6 punches waste materials from materials and then continuously pushes the waste scraps to downwards enter the scrap collecting hole cavity 12, the waste scraps entering the punching hole cavity 11 after the punching of the male die 6 can smoothly fall into the scrap collecting hole cavity 12, because the minimum hole diameter of the punching hole cavity 11 is smaller than the hole diameter of the scrap collecting hole cavity 12, and the maximum hole diameter is equal to the hole diameter of the scrap collecting hole cavity 12, the arrangement is convenient for the waste scraps falling from the punching hole cavity 11 to vertically fall into the scrap collecting hole cavity 12, so that the waste scraps are clamped at the connection part of the punching hole cavity 11 and the scrap collecting hole cavity 12 during the discharge, at the moment, the air blowing device 2 blows the waste scraps on a film, the fan column 21, the fan blade ball 22 and the fan blade 23 in the air blowing device 2 are mutually matched with each other, the through hole can be ventilated and can perform heat dissipation, meanwhile, the connecting pipe 9 is arranged outside the air blowing device 2, the air can be concentrated upwards, and the waste scraps at the lowest end can be successfully ejected out of, therefore, the scraps in the blanking hole cavity 1 are discharged, and an operator only needs to clean the scraps on the upper template 3 without taking out the scraps from the blanking hole cavity 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
