如何处理小型金属零件的毛刺,这是一个人们不十分重视而又非常棘手的问题。这在标准件行业中尤为突出,如六角槽螺母的去毛刺是槽螺母切槽后的一道必不可少的生产工序。目前,国内采用的手工和机械去除法,一般均未达到最理想的效果。因而,槽螺母去毛刺已成为标准件行业中急待解决的课题之一。对此,曾进行了一些试验,并设计了一种夹头式槽螺母去毛刺冲模、一、该冲模的结构和持点这种冲模由弹簧切刀冲头、底座、锁母、波形垫圈等工件组成(见图一)。其特点是:采用固定式切刀,并将其设计成弹簧夹头式。工作时,由锁母压迫波形垫圈将夹头和 How to deal with the burrs of small metal parts, which is a problem that people do not attach great importance to and very difficult. This is particularly true in the standard parts industry, such as the deburring of hexagonal slotted nuts, which is an essential manufacturing process after slotted slotted grooving. At present, the domestic manual and mechanical removal methods generally do not achieve the best results. Therefore, the slot nut deburring has become one of the standard parts industry issues to be solved. In this regard, some experiments have been carried out, and designed a chuck slot nut deburring die, the die structure and holding point of this die by the spring cutter punch, base, lock the mother, wave washers, etc. Workpiece composition (see Figure I). Its features are: the use of fixed cutter, and designed as a collet chuck. Work, the pressure by the lock mother wave washers will be and
