FIELD: metallurgy. ^ SUBSTANCE: invention refers to punching. The installation consists of a puncheon, matrix, and of facility for measuring value of deformation installed inside an element subject to control. During punching value of deformation of the controlled element is measured. Also there is the facility for control of deformation value. It is installed in the element subject to control and it controls value of deformation of the controlled element during punching. Facilities for measuring value of deformation and control over value of deformation are arranged at specified space one from another and from surface of the element subject to control. ^ EFFECT: reduced surface deformations, increased stability of shape. ^ 16 cl, 25 dwg, 11 tbl, 10 ex |
