Title:
MEASUREMENT METHOD AND DETERMINATION METHOD FOR MEASURING DEFORMATION AMOUNT OF MEMBER TO BE STRUCK BY IMPACT FORCE OF PERCUSSION DEVICE
Document Type and Number:
Japanese Patent JP2023092643
Kind Code:
A
Abstract:
To provide a measuring method for measuring the deformation amount of a member to be struck by a striking force of a striking device capable of quantitatively evaluating the striking force by a simple method.SOLUTION: Disclosed is a measurement method for measuring the deformation amount of a member to be struck by a striking force of a striking device. The striking device is a device which strikes a cast product with a hammer in order to remove sand cores from the cast product in which the sand cores have been cast. The measurement method includes: a first step of installing the member to be struck at the same position as a striking position of the cast product; a second step of striking the member to be struck with the hammer; and a third step of obtaining the deformation amount of the struck member to be struck in a striking direction.SELECTED DRAWING: Figure 2
