Steel wire deforming apparatus for bead cores
View Patent ↗A deforming apparatus ( 10 ) for a steel wire (W) for a bead core (X) includes a deforming roller ( 12 ), a guide device ( 20 ), and a deforming amount changing device ( 30 ). The deforming roller ( 12 ) is arranged upstream of a molding drum ( 50 ), which molds the bead core (X) by winding the steel wire (W). The steel wire (W) is mounted on the deforming roller ( 12 ) in a curved manner such that the deforming roller ( 12 ) deforms the steel wire (W). The guide device ( 20 ) is arranged upstream of the deforming roller ( 12 ) and guides the steel wire (W) to the deforming roller ( 12 ). The deforming amount changing device ( 30 ) changes the amount by which the steel wire (W) is mounted on the deforming roller ( 12 ) in a curved manner by moving the guide device ( 20 ) with respect to the deforming roller ( 12 ).
1. A deforming apparatus for a steel wire for a bead core, comprising:
a molding drum that molds a bead core by winding a steel wire;
a deforming roller that is arranged upstream of the molding drum, wherein the steel wire is mounted on the deforming roller in a curved manner such that the deforming roller deforms the steel wire;
a guide device that is arranged upstream of the deforming roller and guides the steel wire to the deforming roller; and
a deforming amount changing device that changes a length by which the steel wire is mounted on the deforming roller in a curved manner by moving the guide device toward or separately from the deforming roller without changing a position of the deforming roller with respect to the molding drum.
2. The deforming apparatus according to claim 1 , wherein the deforming apparatus includes a pressing roller that is arranged downstream of the deforming roller and is located at a fixed position relative to the deforming roller.
3. The deforming apparatus according to claim 1 , wherein the deforming apparatus includes a scale corresponding to positions of the guide device, and the scale represents a desired diameter of the bead core molded by the molding drum.
4. The deforming apparatus according to claim 3 , wherein the deforming amount changing device includes a manipulating portion manually operated to move the guide device.
5. The deforming apparatus according to claim 4 , wherein the manipulating portion is a wheel handle, and the deforming amount changing device includes a conversion mechanism that converts rotation of the wheel handle to linear movement and transmits the linear movement to the guide device.
