STAMPING PLATE Russian patent published in 1999 - IPC

FIELD: light industry, particularly, manufacture of footwear; applicable in cutting-stamping shops of shoe plants. SUBSTANCE: stamping plate has plate body assembled of separate bristle-like fibers of the same length and taking impact during stamping. Body working and supporting surfaces are parallel to each other and formed by set of fiber ends. Each fiber is located normally to supporting surface. Rigid metal plates with holes at ends are located over long sides of plate. Two threaded rods with nuts are intended for tightening of metal plates. To increase service life of process equipment, fiber diameter equals 0.7-0.8 size of dull part of cutting edge of cutter. Ends of fibers of supporting surface are rigidly interconnected. Fiber ends of working surface are free and have low friction coefficient. Each rigid metal plate consists of two members with compensation flexible members located between them. Installed on two threaded rods are bushings of rectangular cross-sections whose height of side face is less than fiber length through depth of introduction of cutter plate into stamping plate. In this case, ends of fibers of supporting surface are glued with latex. To reduce friction coefficient of cutter blade with respect to fibers, plate working surface is periodically lubricated with mineral oil. EFFECT: increased service life of process equipment. 3 cl, 1 dwg
