SHOT PEENING ARRANGEMENT FOR HELICAL COMPRESSION SPRINGS

摘要

The present invention relates to the present availability for short blasting of blast chamber 3 and prestressed compression coil spring with one or more centrifugal wheels 4 and a conveying device for feeding and withdrawing compression coil spring 2. In order to provide a spring holding device that provides economic expansion in a simple structure, the spring holding device consists of one or two collet chucks 5 arranged next to the blast chamber 3, the collet chuck being a blast chamber. Moving horizontally to the side of the conveying device consists of a V-block belt arranged parallel to the blast chamber 6.
