FORMING TOOL WITH THREE-AXIS FORCE MEASUREMENT SYSTEM Russian patent published in 2024 - IPC G01L1/22 

FIELD: mechanical engineering.

SUBSTANCE: deforming tool contains a body including a base with two side walls, two side faces, a bottom cover and a top cover. A strain gauge is installed in the central part of the base to measure the force directed along the vertical axis of the working element. A strain gauge is also installed in the central part of each of the lateral integral walls of the base to measure the force on the working element along an axis perpendicular to the lateral integral walls of the base. Two side faces are fixed to the base and have strain gauge sensors installed on their central parts with the ability to measure the force of the working element along the axis perpendicular to the side faces. The lower housing cover is fixed to the upper parts of the side walls of the base and the side faces, and a disk spring is installed in it, on which the lower part of the insert is placed with a sphere held by the upper part of the insert, which, in turn, is fixed by the upper cover. The working element is installed in a sphere with the possibility of axial movement, rotational movement together with the sphere, as well as the influence of its lower part on the strain gauge sensors present in the tool.

EFFECT: increasing the sensitivity and accuracy of measuring forces and moments during incremental shaping, as well as improving the quality of the resulting products.
