Abstract
In an apparatus for forming a pair of disk-shaped metal blanks into grooved wheels, a spindle head is mounted on a support base and has rotatably supported therein a spindle for mounting a pair of mounting dies on opposite ends thereof. A pair of clamp heads are mounted on the support base at opposite sides of the spindle head and slidably and rotatably support a pair of clamping dies for clamping two blanks in cooperation with the mounting dies. A pair of brackets are rotatably suppoted on the support base and rotatably carry a pair of rollers for forming the blanks into grooved wheels. The brackets are independently rotated and the rotational movements thereof are individually restricted.
Claims6
An apparatus for forming a pair of disk-shaped metal blanks into grooved wheels comprising:
- a support base;
- a spindle head mounted on said support base;
- a spindle rotatably supported within said spindle head;
- means for rotating said spindle;
- a pair of mounting dies mounted on opposite ends of said spindle;
- a pair of clamp heads mounted on said support base at opposite sides of said spindle head;
- a sleeve slidably received in each of said clamp heads;
- a clamp shaft rotatably journalled in said sleeve in coaxial relation with said spindle;
- means for moving said sleeve in an axial direction;
- a clamp die mounted on one end of said clamp shaft for clamping a blank in cooperation with said mounting die;
- a pair of brackets rotatably supported on said support base;
- a pair of carriers supported on each of said brackets and spaced from each other in an axial direction of said spindle;
- a roller shaft rotatably journalled between said pair of carriers;
- a roller carried on said roller shaft for forming the blank into a grooved wheel;
- one of said pair of carriers being fixedly supported on said bracket and the other carrier being slidably supported in said bracket for a sliding movement in an axial direction of said roller shaft, whereby one end of said roller shaft is disengaged from said slidable carrier by a sliding movement thereof;
- means for independently rotating said pair of brackets;
- and
- means for individually restricting rotational movements of said brackets.
