摘要： A perforation apparatus includes a punch housing 4 having an aperture through which 8 piping is longitudinally and rotationally moveable and one or more punches 7 arranged radially around the aperture to perforate the piping, a driven annular housing 3 including an aperture corresponding to the punch housing aperture, a punch retracting mechanism 5, and one or more rollers 6 axially secured to the annular housing, with the annular housing 3 rotatable adjacent the punch housing 4 such that the or each roller 6 rolls around the punch housing 4 and operates the or each punch 7 upon contact, and wherein the retracting 5 mechanism retracts the or each punch after said contact. A control system may be provided to coordinate the longitudinal and rotational movement of the piping with the operation of the punches. A mandrel assembly may also be provided to support the piping during punching and to remove punch waste.

摘要： A perforation apparatus has a mandrel to support at least a part of the piping that is to be perforated from the interior of the piping. A punch housing has an aperture through which the piping is moveable and punches arranged radially around the aperture. At least some of the punches have an associated clamping mechanism that applies a force to the exterior of the piping adjacent the respective punch, to push or hold the piping against the mandrel. A driven annular housing rotates adjacent the punch housing. A plurality of rollers engage a surface on the punches during rotation of the annular housing to operate the punches upon contact and to operate the clamping mechanisms. A punch retracting mechanism retracts the punches after each operation. At least one mechanism longitudinally and rotationally moves the piping relative to the punch housing and drives the annular housing.
