Abstract
A rod-shaped material is reciprocated along a conveyance line while being supported by a plurality of rollers. The material is allowed to pass through a rolling device disposed in the middle of the conveyance line a number of times for rolling operation during reciprocation or conveyance. A pair of rotating devices are disposed on both sides of the rolling device for varying the rolling angle of the material so that a desired rolling may be effected to the material.
Claims6
In a rolling apparatus comprising rolling means and a plurality of rollers arranged along a horizontal conveyor line to allow a material to be rolled to move thereon while supporting the material and having means disposed in the middle of said conveyor line for rolling the material having been conveyed along said conveyor line, and having means disposed on one side of the means for rolling for rotating the material during the process of a reciprocated conveyance thereof along said conveyor line, said means for rotating including:
- (a) a framework construction so disposed that said conveyor line extends therethrough;
- (b) a rotating frame connected to said framework construction rotatable about said conveyor line as central point of rotation thereof;
- (c) a pair of support frames disposed in said rotating frame, having said central point of rotation of said rotating frame therebetween and movable relative to each other to vary the distance therebetween;
- (d) a pair of work holders connected to said support frames, respectively, for taking hold of the material having been conveyed along said conveyor line;
- (e) holding means disposed in close proximity to said work holders for moving said work holders to each other so that the distance between said work holders may be varied;
- (f) each of said framework, said rotating frame, said support frames, said work holders and said holding means being axially aligned with said conveyor line;
- and
- (g) further including work-path correcting means disposed between said rolling means and said means for rotating, said work-path correcting means comprising a pair of locating plates disposed with said conveyor line therebetween and means for moving each of said locating plates independently relative to said conveyor line so that the distance between said locating plates may be varied.
A method for rolling a rod-shaped material comprising the steps of:
- (a) moving a material in a reciprocatory manner along a conveyor line while supporting the material by a plurality of rollers,
- (b) rolling the material a number of times in the course of said movement of the material by passing the material through a rolling means disposed in the middle of said conveyor line,
- (c) rotating the material in the course of said rolling by employing a rotating means disposed on one side of said rolling means, said rotating step being characterized by:
- (d) holding the material by a pair of work holders to allow the material to slide on and between said work holders in the axial direction thereof during rotation;
- (e) rotating the material with the central point of rotation of a rotating frame of said rotating means as the central point of rotation thereof so that the rotation of the material may be made with the greater part of weight of the material being supported by said rollers;
- and
- (f) correcting the work-path of said material after rotation and prior to rolling thereof.
