A concave template is mounted on the lower module, the concave template defines a through hole corresponding to the punch, the upper half of the through hole is a knife edge portion, and the lower half of the through hole is a blanking portion of the aperture extending outward, the knife edge The upper portion of the portion is the same size as the punch, the lower portion of the knife edge portion is a straight hole and the aperture is larger than the diameter of the punch.
As described above, the stamping die of the present invention is matched by the zero gap of the same size of the punch at the time of punching (gap t=0mm), and the lower portion of the blade portion is larger than the diameter of the punch, thereby avoiding excessive wear of the blade side. It can extend the service life of stamping die, and can effectively punch and improve the quality and efficiency of product processing, while reducing the processing precision of stamping die.
為詳細說明本創作之技術內容、構造特徵、所達成目的及功效，以下茲舉例並配合圖式詳予說明。
請參閱第二圖至第四圖，本創作沖壓模具包括一上模組和一與上模組相互對應配合的下模組。
上模組上裝設有一沖頭１，一凹模板２裝設於下模組上，凹模板２對應沖頭１處開設有一通孔２０，通孔２０的上半部為刀口部２１，通孔２０的下半部則為孔徑向外擴展的落料部２２，刀口部２１的上部與沖頭１大小相同。
進一步地，刀口部２１的下部是直孔並且孔徑大於沖頭１的直徑，即刀口部２１下部的孔徑與沖頭１配合留有一定間隙，其孔徑大於沖頭１的直徑（單面間隙t=0.001mm）。而其上部則是經過對凹模板２的上表面於鄰近通孔２０處用外力進行擠壓，使刀口部２１的上部內縮而成為孔徑小於沖頭１（單面間隙t=-0.001mm）；然後藉由沖頭１對通孔２０的刀口部２１進行一次試沖後，使刀口部２１上部的孔徑與沖頭１的直徑相同。
如上所述，本創作沖壓模具的凹模板２對應沖頭１處開設一通孔２０，通孔２０的上半部為刀口部２１，刀口部２１是一直孔，刀口部２１的孔徑大於沖頭１的直徑（單面間隙t=0.001mm），通孔２０的下半部為一孔徑向外擴展的落料部２２，藉由外力擠壓使刀口部２１的上部內縮，然後經由沖頭１一次試沖後，使刀口部２１的上部與沖頭１大小相同。由此，刀口部２１的上部在沖壓時與沖頭１配合為零間隙（間隙t=0mm），刀口部２１的下部保持大於沖頭１的直徑。如此，可避免刀口部２１單邊過度磨損，延長沖壓模具使用壽命，并有效完成原料沖裁，提升加工品質和效率，同時降低對沖壓模具之加工精度的要求。
In order to explain in detail the technical content, structural features, goals and effects of the present invention, the following is a detailed description with reference to the drawings.
Referring to the second to fourth figures, the stamping die of the present invention comprises an upper module and a lower module corresponding to the upper module.
A punch 1 is mounted on the upper module, and a concave template 2 is mounted on the lower module. The concave template 2 defines a through hole 20 corresponding to the punch 1 , and the upper half of the through hole 20 is a knife edge portion 21 The lower half of the hole 20 is a blanking portion 22 whose outer diameter is expanded outward, and the upper portion of the knife edge portion 21 is the same size as the punch 1.
Further, the lower portion of the knife edge portion 21 is a straight hole and the hole diameter is larger than the diameter of the punch 1, that is, the hole diameter of the lower portion of the knife edge portion 21 is matched with the punch 1 to have a certain gap, and the hole diameter is larger than the diameter of the punch 1 (single-sided gap t =0.001mm). The upper portion is pressed by an external force on the upper surface of the concave template 2 at the adjacent through hole 20, so that the upper portion of the knife edge portion 21 is retracted to have a smaller aperture than the punch 1 (single-sided gap t=-0.001 mm) Then, after the punching of the knife edge portion 21 of the through hole 20 by the punch 1, the diameter of the upper portion of the knife edge portion 21 is made the same as the diameter of the punch 1.
As described above, the concave template 2 of the stamping die of the present invention has a through hole 20 corresponding to the punch 1 , the upper half of the through hole 20 is a knife edge portion 21 , the knife edge portion 21 is a straight hole, and the aperture of the knife edge portion 21 is larger than the punch 1 The diameter (single-sided gap t=0.001 mm), the lower half of the through hole 20 is a blank portion 22 whose outer diameter is expanded, and the upper portion of the knife edge portion 21 is retracted by external force pressing, and then passes through the punch 1 After one trial run, the upper portion of the knife edge portion 21 is made the same size as the punch 1. Thereby, the upper portion of the knife edge portion 21 is fitted with the punch 1 at a zero gap (gap t = 0 mm) at the time of pressing, and the lower portion of the knife edge portion 21 is kept larger than the diameter of the punch 1. In this way, the excessive wear of the knife edge portion 21 on one side can be avoided, the service life of the stamping die can be prolonged, the blanking of the raw material can be effectively completed, the processing quality and efficiency can be improved, and the processing precision of the stamping die can be reduced.
