专利汇可以提供Straightening apparatus for elongated tubular and rod stock专利检索,专利查询,专利分析的服务。并且A straightening pass in an apparatus for straightening of elongated tubular or rod stock has a concave skew roll and a composite second skew roll located opposite the concave roll with reference to the center line of the pass. The second skew roll has a driven median section provided with two coaxial trunnions and two outer sections each of which has a disk eccentrically mounted on a trunnion and a stock-engaging ring which is rotatable on the respective disk. The disks are angularly adjustable on their trunnions and are adjustably coupled to a holder for the second skew roll. The rings can be rotated in response to rotation of the median section by providing them with internal gears which receive torque from gears provided on the respective trunnions.,下面是Straightening apparatus for elongated tubular and rod stock专利的具体信息内容。

1. In a straightening apparatus for elongated tubular or rod stock, a straightening pass having a center line and including a plurality of skew rolls whose axes are inclined with reference to said center line, one of said skew rolls comprising a plurality of sections including a fIrst section whose axis coincides with the axis of said one skew roll and at least one second section which is eccentric with reference to said first section and is movable about an axis which is parallel to the axis of said one skew roll.
2. A pass as defined in claim 1, wherein another of said skew rolls is located substantially diametrically opposite said one skew roll with reference to said center line.
3. A pass as defined in claim 1, wherein said one skew roll comprises two second sections which flank said first section.
4. A pass as defined in claim 3, wherein said first section comprises a pair of coaxial trunnions, one for each of said second sections, each of said second sections comprising an inner annular member rotatably mounted on the respective trunnion and an outer annular member surrounding the respective inner member.
5. A pass as defined in claim 4, wherein each of said inner annular members is a disk whose axis is parallel to the axis of the respective trunnion and each of said outer annular members is a stock-engaging ring which is rotatable about the respective disk and is coaxial therewith.
6. A pass as defined in claim 3, further comprising a holder rotatably supporting said one skew roll, and adjusting means mounted on said holder and adjustably coupled with said second sections.
7. A pass as defined in claim 6, wherein said first section comprises a pair of coaxial trunnions, one for each of said second sections, each of said second sections comprising a disk rotatably mounted on the respective trunnion and having an axis which is parallel to the axis of said one skew roll, said adjusting means comprising threaded members articulately connected with said holder and adjustably coupled with said disks.
8. A pass as defined in claim 3, wherein each of said second sections comprises an inner annular member which is turnable relative to said first section about an axis parallel to the axis of said first section and an outer annular member which is coaxial with and surrounds said inner annular member, and further comprising means for rotating said outer annular members in a predetermined direction.
9. A pass as defined in claim 8, wherein said means for rotating said outer annular members comprises internal gears provided in said outer annular members, means for rotating said first section in said predetermined direction, second gears secured to said first section, and additional gear means arranged to transmit torque from said second gears to said internal gears in response to rotation of said first section.
10. A pass as defined in claim 9, wherein said additional gear means are mounted in the respective inner annular members.
11. A pass as defined in claim 3, wherein said first section comprises a pair of coaxial trunnions, one for each of said second sections, each of said second sections comprising an inner annular member rotatably mounted on the respective trunnion and having an axis which is parallel to the common axis of said trunnions, and an outer annular member which surrounds the respective inner annular member and has a conical external stock-engaging surface.
12. A pass as defined in claim 11, wherein said outer annular members are coaxial with the respective inner annular members and the diameters of said external surfaces decrease in directions toward said first section, the axes of said inner annular sections being disposed at the opposite sides of the common axis of said trunnions.
