Abstract
A rotary bending tool, consisting of a rotary bending head, a saddle block with bearing surfaces and retaining key for holding the rotary bending head, a restoring member for the rotary bending head and a bottom die, the bearing assembly of the rotary bending head being equipped with a continuous lubricating device. The continuous lubricating device consists preferably of lubricant chambers, which are fed via a lubricant-delivery duct. Preferably the restoring member for the rotary bending head is integrated in the lubricant-delivery duct.
Claims15
A rotary bending tool comprising:
- a saddle block having cylindrical bearing surfaces,
- a rotary bending head having cylindrical surfaces journalled by the cylindrical bearing surfaces of said saddle block,
- a retaining key carried by said saddle block having a bearing surface for retaining said rotary bending head,
- a member in said saddle block for restoring said rotary bending head to an initial position after rotation thereof in said saddle block,
- a die for engagement by a component to be deformed by said rotary bending head,
- at least one lubricant chamber in said saddle block in fluid communication with said bearing surfaces and having an extension to an exterior surface of said saddle block to enable lubricant to be introduced into said lubricant chamber from the exterior of said bending tool, and
- a plug in said saddle block for closing said extension of said lubricant chamber.
