Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1-6, a hardware stamping die for preventing adhesion of waste materials comprises a hardware stamping die composed of an upper die 1 and a lower die 2, wherein the middle part of the lower die 2 is provided with a hollow through groove 22, the lower die 2 is provided with a side opening cavity 21 communicated with the through groove 22, the through groove 22 is communicated with an air pump 3 through a connecting conduit 31, the connecting conduit 31 is not less than two and is respectively connected with the input end and the output end of the air pump 3, the upper die 1 is provided with a side flange 11 matched with the size of the side opening cavity 21, during the stamping production of sheet metal parts by the hardware stamping die composed of the upper die 1 and the lower die 2, the working air pump 3 adsorbs the waste materials generated in the stamping process, so that the waste materials enter the through the side opening cavity 21 into the through groove 22 and are finally led out through the connecting conduit 31 at the output end of the air pump 3, when the waste materials are led out, the upper die, the adsorption force to the scraps is opposite to the moving direction of the upper die 1, so that the scraps are further prevented from synchronously moving upwards or adhering to the sheet metal parts along with the upward movement of the upper die 1.

The side convex plate 11 is provided with a gap plate 12, the size of the gap plate 12 is matched with the size of a gap groove 23 on the side opening cavity 21, a stamping gap is arranged between the gap groove 23 and the gap plate 12 when the gap groove 23 and the gap plate 12 are overlapped, under the matching action of the gap plate 12 and the gap groove 23, the stamping gap prevents the upper die 1 and the lower die 2 from excessively colliding, and simultaneously prevents scraps from splashing outwards under the stamping action of the upper die 1 and the lower die 2.

The through grooves 22 are annularly distributed in the middle of the lower die 2, and the through grooves 22 which are annularly distributed effectively improve the strength of the waste attraction force and the effectiveness of waste storage while ensuring the air flow mobility and the waste circulation between the waste and the connecting conduit 31.

Connecting duct 31 is equipped with the diffuser 32 that enlarges flow channel with the junction of logical groove 22, and diffuser 32 can be dismantled with lower mould 2 or connecting duct 31's junction, because the relative connecting duct 31 of waste material produces the jam easily, expands between connecting duct 31 and the diffuser 32 and flows the passageway and effectually prevents that the waste material from blockking when leading out through groove 22, and demountable installation is convenient for carry out timely, convenient clearance to the waste material simultaneously.

The junction of diffuser 32 and connecting pipe 31 or lead to one side that groove 22 is close to diffuser 32 and be equipped with filtering plate 4, filtering plate 4 carries out effectual isolation to waste material and air current, what make the 3 output of air pump connecting pipe 31 derive is the air current, accomodate the waste material between leading to groove 22 and filtering plate 4, carry out the dismouting of subassembly and the clearance of sweeps through diffuser 32, filtering plate 4 is the filter plate of connecting promptly, the middle part of filter plate is equipped with the filtration pore that a plurality of made the relative air current separation of sweeps.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present disclosure.
