Definitions
- the device further comprises at least one support element, which is arranged on the inside of the housing substantially opposite to the sealing element.
- the sealing element and / or the support element along the inner peripheral shape and / or in the axial direction of the housing are adjustable. This allows the device in a simple manner
- Housing interior are positioned so that forces cancel at least partially.
- the support elements and / or the sealing elements are arranged interchangeably in the housing. This allows individual
- Embodiment of the invention a perspective sectional view of the device of the first embodiment with a non-sealed workpiece, a perspective sectional view of the device of the first embodiment with sealed workpiece, a schematic horizontal sectional view of the device according to a second embodiment, and
- Figure 5 is a schematic vertical sectional view of the device of the second embodiment.
- the base plate 24 forms the interface between the device 1 and the rest of the machine.
- Each sealing element 4 On an inner side of the housing 2, a plurality of sealing elements 4 arranged one above another and a plurality of supporting elements 7 are arranged, which are positioned substantially opposite the sealing elements 4.
- Each sealing element 4 has a movable piston 6 for
- FIG. 3 shows the device 1 in the clamped state of the workpiece 3, in which the piston 6 of each sealing element 4 in each case closes an opening 5 of the workpiece 3 which is not visible in this illustration, and the autofrettage
- Opening diameters are easily adapted and used.
- the device according to the invention minimizes the number of moving components required for the autofrettage process and limits the power flow to a few components inside the device. Because of the circulating
