Abstract

Lorsqu'on perce une pièce dure, lorsque la mèche sort du trou qu'elle vient de forer, la résistance cesse brusquement et la mèche fait un brusque déplacement vers l'avant. Si dans cette course rapide elle rencontre un obstacle, elle casse. L'appareil amortisseur 1 proposé se place entre la perçeuse et le mandrin forte-mèche 2. Un ressort placé entre une embase 4 et une pièce moletée 8 qui permet de régler sa tension initiale va absorber les chocs, et une rondelle plastique 5 interposée entre l'embase 4 et un épaulement 1 va servir de coussin amortisseur des réactions du ressort. Peut se monter sur tous les dispositifs de perçeuses.
