Title:
SOFT PUNCH METAL MICRO MEMBER FORMING FORCE MEASURING DEVICE AND MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/212423
Kind Code:
A1
Abstract:
A soft punch metal micro member forming force measuring device that uses a flexible medium (24) as a punch. The soft punch metal micro member forming force measuring device comprises a force measuring component (12), a forming die (21), a pressing plate (22), and a force applying mechanism (23). The force measuring component (12) is provided on a workbench, a lower surface of the forming die (21) abuts against the force measuring component (12), the lower end of the force applying mechanism (23) applies a downward pressure on and presses a flexible medium (24) that is positioned within a storage bin (221), the flexible medium (24) presses a metal blank (30) to enter a die cavity (211) or cuts the blank by using a peripheral cutting edge of the die cavity (211), and simultaneously the forming die (21) transfers the forming force received by the metal blank (30) to the force measuring component (12), and the force measuring component (12) transmits real-time data of the forming force to a computer. Also disclosed is a measuring method. In the forming force measuring device, the forming die (21) is directly provided on the force measuring component (12), such that the forming force that acts on the metal blank (30) is transferred onto the force measuring component (12) by means of the forming die (21), enabling the forming force received in the micro-forming process of the metal blank (30) to be accurately measured.
