发明名称 Metal working attachment for portable power tool
摘要 A metal forming tool attachment includes a body assembly having a front part and a rear part. A rotary forming element journalled on the rear part is driven by an input shaft which projects from the rear part for coupling engagement with the output shaft of an associated power tool. Another rotary forming element journalled for free rotation on the front part cooperates with the driven rotary forming element to form a nip region therebetween. An adjustment lever mounted on the rear part cooperates with a threaded member mounted in fixed position on the front part to move the front part generally toward and away from the rear part whereby the nip region between the forming rolls may be adjusted. A pair of spaced apart rotary forming elements carried by a mounting plate pivotally supported on the front part may be substituted for the single rotary forming element carried by the front part to adapt the tool attachment to perform a radial bending operating. The tool attachment may also be set up to perform a circular disk cutting or trimming operation.
