Abstract

"CONJUNTO DE MATRIZ PARA LAMINAçãO PARA UM PROCESSO DE FABRICAçãO PLANO DE ROSCA TIPO PARAFUSO". Um par de matrizes para laminação de rosca (10,12), para fabricação de parafusos auto-perfurantes, auto-atarraxantes ou do tipo trado (21) empregam uma elevação descentrada e superfícies de formação de ponta assimétricas (54, 64) para aprimorar a remoção de rebarba na ponta (28) do prafuso."LAMINATION MATRIX SET FOR A SCREW SCREW TYPE SCREENING MANUFACTURING PROCESS". A pair of dies for thread rolling (10,12), for the manufacture of self-tapping, self-tapping screws or auger type (21) employ a decentralized elevation and asymmetric tip forming surfaces (54, 64) to improve the removal of burr on the tip (28) of the screw.
