Definitions
- the present invention relates generally to apparatus for pressing fittings to 5 connect sections of pipe and, more particularly, apparatus for use in pressing such fittings.
- piston will move a fixed distance along a linear path to press the piston with its rollers against the arms.
- the rollers engage ends of the jaws in line engagement and cause them to pivot and press the compression fitting disposed between the jaws.
- An example of a press tool including a press jaw is provided in Figures 1 and 2.
- pressing tools are designed such that each activation of the tool results in movement of the hydraulic piston along a fixed distance path.
- the linear distance the piston moves for a given tool is often referred to as the "stroke" of the tool.
- the force output of the piston as it moves along the stroke will depend on the sizing, geometry and other characteristics of the hydraulic cylinder and piston.
- Figure 14 illustrates a press ring interlock concept that may be used with any multi-step press rings assemblies including, but not limited to the multi-step press rings assemblies discussed above in connection with Figures 6-11.
- Figure 3 generally illustrates the use of a press ring assembly to accomplish a press connection.
- the pressing tool 12 is coupled to a press ring actuator assembly 30.
- the press ring actuator assembly is similar in construction to the press jaws 14 discussed above, with the primary difference being that the arms of the press ring actuator assembly 30 are designed to interface with the press ring assembly 32.
- press ring assembly 32 is formed of two generally half-round shaped sections that are coupled together at a pivot point. In operation, the press ring assembly 32 is placed about a press fitting 35 to be pressed, the tips of press ring actuator assembly 30 are placed within notches formed on the press ring assembly 32 and the pressing tool 12 is actuated. Actuation of the pressing tool causes movement of the arms of the press ring actuator assembly 30 and compression of the press ring assembly 32 and the fitting 35 about which it is placed.
- the replaceable tips are sized differently, the manner in which they interface with the press ring assembly will differ and it is possible to efficiently use the press ring actuator assembly of Figure 4 to readily perform a two-step pressing operation.
- the first set of tips 42 could be used to perform an initial press operation through use of the press ring actuator assembly 40 and a press ring assembly and a press tool in a conventional manner.
- the press ring actuator assembly 40 could then be removed from the press ring, the tips 43 could be substituted for tips 42, and the pressing tool could be coupled to the press ring assembly through the modified press ring actuator assembly 40. Actuation of the press tool a second time could then provide the necessary additional work to complete the press operation.
- Figure 7 illustrates an alternate embodiment to that of Figure 6.
- a press ring assembly 70 is illustrated that includes recesses 72a and 72b and movable members 74a and 74b.
- the movable members 72a and 72b may be adjusted to change the geometry of the recesses 72a and 72b to facilitate multi-step pressing operations.
- the movable members 74a and 74b are adjusted though linear movement (e.g., sliding).
- FIG. 8A illustrates yet another embodiment of movable elements where a press ring assembly 90 is provided with slidable elements 94a and 94b located in recesses 92a and 92b which move into positions to change the manner in which the press ring assembly 90 interfaces with a press ring actuator assembly applied to the ring assembly 90.
- a pressing operation is performed wherein the pressing process is broken down into two or more discrete steps including at least one step where a press is performed to provide a retention press to retain the fitting on the pipe to which the fitting is applied and where at least one press is performed to press the seal bead to provide a snug seal.
- Figure 15A and 15B illustrate a press ring assembly 150 that is particularly suited to this fo ⁇ n of multi-step pressing.
- segments 152A-1 and 152A-2 When so positioned, the segments 152A-1 and 152A-2 will be positioned over a part of the fitting to provide an initial retention press to one of the pipe elements to be coupled by the fitting; segments 152B-1 and 152B-2 will be positioned to press an area of the fitting to provide a sealing press of a seal bead; and segments 152C-1 and 152C-2 are positioned so as to provide a retention press for another pipe element to be coupled by the fitting.
- the tips of a pair of actuator jaws will be positioned within the pockets defined by segments 152A-1 and 152A-2 and the tool to which the jaws are coupled will be activated, thus producing a retention press securing the fitting at issue to one of the pipe elements to be coupled.
- the tool will then be moved such that the tips of the actuator arms are positioned in the pockets defined by segments 152B-1 and 152B-2 and the tool will be actuated providing a seal bead press.
- the tips of the actuator jaws will be moved to the pockets defined by segments 152C-1 and 152C-2 and actuated for a third time, providing a second retention press.
- the failed press is ensured by the fact that the notches 164 and 165 (and the corresponding notches on the underside of the ring) are designed so that activation of the outer segments before activation of the intermediate segments will result in an engagement of the outer segments with the intermediate segments and, as such, a press of the outer segments before the press of the inner segments are complete will result in the actuator tool attempting to perform two pressing operations. Because, in the applications for which the ring assembly 160 will be used, the work output of the tool is insufficient to perform two press operations, the attempted press operation will fail. If the intermediary press is performed first, the intermediate segments 162B-1 and 162B-2 will tend to be closed or partially closed as a result of the deformation of the press fitting in that area.
- FIG. 18A and 18B A still further advantage the apparatus of Figures 18A and 18B is that it allows the use of main actuators other than a standard press tool to attain a desirable press.
- actuating elements other than a press tool could be used to achieve the desired movement of the first piston.
- Embodiments are envisioned where a feed screw was used to move the first piston.
- Such alternate embodiments could allow for the use of press fittings in situations where the costs of a full pressing tool are not justified and/or in situations where electricity is not available and/or undesirable to use.
