摘要： An apparatus for the section-wise autofrettage of gun barrels (22) by a hydraulic pressure generated inside the barrel. The apparatus (1, 1′, 1″) comprises a mandrel-shaped insert (2, 2′, 2″) inserted into the barrel (22) from the breech opening. A first sealing device (3) is disposed at one end of the insert (2, 2′, 2″), and has a seal packet (5) disposed on a seal seat (4) of the insert (2, 2′, 2″). The seal seat (4) is limited at the front by a threaded sleeve (7) screwed onto the insert (2, 2′, 2″), and an annular intermediate part (8) adjoining the threaded sleeve (7) at the rear. The seal packet (5) includes at least one O-ring (10) held by a shoulder (9) of the mandrel-shaped insert (2, 2′, 2″), and a high-pressure seal (15) formed by two partial rings (13, 14) that are connected to one another by a conical contact surface (16).

摘要： Ingots hot from rolling are pierced to form a hollow ingot by means of an internal tool of a press or skew-rolling line, and are subsequently elongated to form a tubular bloom by a stretching unit provided with a mandrel rod, and are finally finish-rolled. When inserting or withdrawing the internal tool into or out of the hollow ingot or the mandrel rod into or out of the tubular bloom, inert gas is introduced into the freed interior space in order to prevent scaling of the interior wall of the tubular bloom.

摘要： The rollers of a push bench for the production of tubular blooms are axially displaceably journalled on respective spindles so that the rollers are centered by the bloom. For machining the working surfaces of the rollers, the rollers, or their shafts to which they are fixed, can be axially locked in position and the roller shaft has a releasable coupling for coupling the roller shaft to a drive motor or drive shaft, whereby all the rollers can be machined simultaneously without removing them from the stand.
