Abstract
An independent mandrel trip system wherein a mandrel support block retaining a mandrel is connected to a shaft mounting block in a manner such that the mandrel support block can be reciprocatingly retracted and extended relative to the shaft mounting block in a direction perpendicular to the longitudinal axis of the mandrel.
Claims16
A mandrel trip apparatus comprising a mandrel support block retaining a mandrel, said mandrel being cylindrical and having a longitudinal axis, wherein said mandrel support block is connected to a shaft mounting block in a manner such that said mandrel support block is reciprocatingly movable relative to the shaft mounting block in the direction perpendicular to said longitudinal axis of said mandrel,
- and further comprising mandrel trip actuator means comprising a piston and a cylinder housing receiving said piston, wherein said cylinder housing reciprocates in the direction parallel to said longitudinal axis of said mandrel.
In an apparatus comprising a cylindrical mandrel having a longitudinal axis and adapted to receive a work piece thereon upon which a process is to be effected, wherein it is required under certain conditions that the mandrel be reciprocatingly moved from an active position to an inactive position, the apparatus further comprising sensing means to actuate such reciprocal movement, the improvement comprising:
- a mandrel support block retaining said mandrel and connected to a shaft mounting block in a manner such that said mandrel support block is reciprocatingly movable relative to the shaft mounting block in the direction perpendicular to said longitudinal axis of said mandrel,
- and further comprising a mandrel trip actuator means comprising a piston and a cylinder housing receiving said piston, wherein said cylinder housing reciprocates in the direction parallel to said longitudinal axis of said mandrel.
A mandrel trip apparatus comprising:
- a mandrel support block retaining a mandrel, said mandrel being cylindrical and having a longitudinal axis, connected to a shaft mounting block in a manner such that said mandrel support block is reciprocatingly movable relative to the shaft mounting block in the direction perpendicular to said longitudinal axis of said mandrel;
- a mandrel trip actuator means comprising a piston and a cylinder housing, said cylinder housing adapted to reciprocate in the direction parallel to said longitudinal axis of said mandrel;
- two slots disposed on said mandrel support block;
- and
- two cam rollers connected to said cylinder housing, wherein said cam rollers are positioned within said slots such that movement of said cylinder housing results in movement of said mandrel support block relative to said shaft mounting block.
