Abstract:
    The invention relates to a measurer of non-friction tension bar deformation resistance and friction resistance used in shaping sheet. Wherein, it comprises non-friction tension bar mould (1) and connected force sensor used to measure the tension bar resistance. Said mould (1) comprises convex mould, edge compressor, concave mould, and base; the convex and concave moulds are assembled; the convex mould roller (11), left and right concave mould rollers (14, 19) both use the axle structure whose two ends have rolling bearing. The invention also provides relative measure method.
