Abstract
(EN) A low-pressure internal water supply thin-wall drill bit, comprising a working ring (1) and discharging recesses (2). The working ring (1) is of a cylindrical structure; multiple discharging recesses (2) are provided and annularly distributed in the bottom of the side wall of the working ring (1). Each discharging recess (2) is formed in the bottom of the outer side wall of the working ring (1) and is recessed towards the inner side of the working ring (1) by a preset distance, and the recessed distance is smaller than the thickness of the side wall of the working ring (1).
(FR) L'invention concerne un trépan à paroi mince à alimentation interne en eau basse pression, comprenant une bague de travail (1) et des évidements d'évacuation (2). La bague de travail (1) présente une structure cylindrique ; de multiples évidements d'évacuation (2) sont disposés et répartis de manière annulaire dans le bas de la paroi latérale de la bague de travail (1). Chaque évidement d'évacuation (2) est formé dans le bas de la paroi latérale extérieure de la bague de travail (1) et est évidé vers le côté interne de la bague de travail (1) suivant une distance prédéfinie, la distance d'évidement étant inférieure à l'épaisseur de la paroi latérale de la bague de travail (1).
(ZH) 一种低压内供水薄壁钻头,包括工作环(1)和排料槽(2);工作环(1)为圆筒结构,排料槽(2)设有多个,呈环形分布在工作环(1)侧壁的底部;排料槽(2)设置在工作环(1)外侧壁的底部并向工作环(1)内侧凹陷预设的距离,且凹陷的距离小于工作环(1)侧壁的厚度。
