Definitions
- the invention relates to a pressing tool for pressing 00004 pipe ends.
- 00005 00006 For heating and tap water installations, 00007 systems are increasingly being used in which the pipe ends 00008 are provided with press fittings. This eliminates 00009 screwing, welding or soldering work, which can lead to an undesirable structural change in metal pipe 00010 00011.
- the pressing can also be carried out in a very short time in 00014.
- the 00016 fitting When connecting 00015 metal pipes made of copper or stainless steel, the 00016 fitting has, for example, a tubular end into which the pipe to be connected is plugged. This area of the fitting is then deformed by external forces, for example hexagon-shaped.
- 00020 This creates a positive connection of 00021 fitting and pipe, whereby the 00022 forces occurring under internal pressure are transmitted. Tightness is ensured by a seal built into the 00023.
- the majority of the compressed pipe diameter 00025 is below about 40 mm. In this area, it is common to carry out the pressing using pliers-like tools.
- This 00030 principle is for larger pipe diameters - e.g. B. from 00031 nominal size 63 - no longer practical, because the Press00032 forces and thus the pliers become very large and in this case less favorable scissors movement in 00033 leads to a 00034 uneven pressing.
- 00043 is that a bearing and an abutment on the
- 00048 is acted upon by a tensioning device.
- 00050 has a hydraulic cylinder.
- the press die is in the
- 00074 trize in an open position approximately in the axial direction
- 00075 device of the jig are aligned or light
- 00078 has an inner sleeve portion.

- FIG. 8 the pressing tool in the stop-limited opening position of the pressing die, relating to a first 00187 embodiment of the stop;
- FIG. 9 a representation corresponding to FIG. 8, 00190 relating to a further embodiment;
- FIG. 10 shows a further alternative embodiment of the 00193 press tool; and 00194 00195 FIG. 11 shows the section along the line XI-XI in FIG. 10.
- 00196 00197 A pressing tool 1 is shown and described first with reference to 00198 FIG. 1, which essentially 00199 consists of a pressing die 2 and a clamping device 3 00200 composed.
- the pressing die 2 consists of several, preferably 00201, the same pressing members 4, which are either articulated to one another in an articulated manner, directly or in the manner of a chain by means of straps 00203 40.
- each pressing member 00211 an inner sleeve section, which is formed as 00212 00212, a dome section 34 extending essentially perpendicular to a press jaw 00213.
- 00215 00216 To carry out pressing, the press die 2 designed as a chain 00217 is placed around the tube 5.
- the clamping device 3 is arranged on the press 00220 die 2, which clamping device 3 closes the 00221 press die 2 in the tangential direction.
- the clamping device 3 has a hydraulic cylinder 00224 7, which surrounds the pressing member 4 in a fork shape and is connected to this 00225 via a bolt 9 00226 forming a bearing 8 (cf. FIG. 4).
- the fork arms that act on bearing 8 are identified by reference number 10.
- This location is z. B., as shown, 00243 defined by a unilaterally extended fork 15 of the end piece 00244 kes 12, which strikes against the bolt 14. 00245 00246 The end piece 12 is in a locked position 00247, in which the end piece 12 is held by a locking bolt 00248 16. Here, a bias spring 17 00249 is maximally compressed. 00250 00251 Fig. 2 shows the arrangement after the locking pin 16 00252 ben by manual pressure actuation the end piece 12 ben00253 ben, which now presses with the relatively low 00254 force of the bias spring 17 against the bolt 14 or the 00255 abutment 13.
- the entire pressing device is now held on the 00257 fitting.
- the preload 00261 spring 17 is compressed again until the piston 11 touches the 00262 end piece 12.
- the locking pin 16 shifts 00263 back to its starting position, with which the end piece 00264 12 snaps in turn.
- connection can continue
- the locking tool essentially consists of
- 00312 24 is fully enclosed.
- the pliers leg 23 is for
- a compression spring 26 holds the pliers legs 23, 24 under 00316 a slight preload, so that the press die 2 00317 and the closing tool automatically on the tube 5 zen. 00319 00320 Furthermore, two 00321 cylindrical pins 27 are provided between the pliers legs 23 and 24, which ensure an approximately symmetrical closing movement of the pliers legs 23, 00323 24. 00324 00325 The closing movement is effected by a drive machine, 00326 of which only the cam rollers 28 and the press 00327 jaw holder 29 are shown, which moves the 00328 cam rollers 28 inwards against the cam tracks of the 00329 pliers legs 23, 24.
- the bolt 30 connects 00330 the closing tool to the drive machine by 00331 inserting it through the tabs 25 and the press jaw holder 29 00332 of the drive machine.
- 00333 00334 It is also conceivable to first mount the press die during assembly 00335 with the aid of a simple clamp belonging to it 00336 and then 00337 to mount a drive machine, e.g. hydraulic cylinder or 00338 pliers closing tool. This procedure 00339 can be advantageous for very large pipe diameters, 00340 since the weight of the press die is considerable.
- FIGS. 8 and 9 show two alternative configurations of the press die 2.
- Both 00344 are characterized by a stop limitation of the individual pressing members 00345 4, 4 ', 4''among themselves.
- 00346 00347 In the exemplary embodiment according to FIG. 8, each 00348 tab 40 is in the area of its eyes 36, which are penetrated by pivot pins 35 for connecting a pressing member to 00349 00350 provided a stop portion 37.
- the 00351 essentially points in the direction of the outer curvature surface 00352 38 of a dome section 34 00353 associated therewith of a press die 4, 4 'or 4''.
- the respective stop section 37 of the bracket 40 is designed in a corner-like manner.
- 00356 00357 In the open position of the press die 2 according to FIG.
- This end face forms a curve extending eccentrically to the bearing 8 00373.
- this end face opposes the Kalot00375 ten section 34 of the pressing member 4, whereby the 00376 outer curvature surface 38 of this pressing member 4 comes against the stop 39 formed in 00377.
- 00378 00379 The entire press die 2 is thus completely stop-limited in its opening movement, which in particular offers 00381 handling advantages.
- the 00382 press tool 1 with the opened press die 2 can be easily guided to the pipe 5 or the like 00384 00384 without the press die 2 in the manner of a conventional 00385 chain tilts backwards.
- 00392 according to FIGS. 1 to 3 can be formed. 00393
- FIG. 9 shows an alternative embodiment of the
- 00410 is the press die 2 in the open position in one
- FIGS. 10 and 11 show a further embodiment
- 00430 has a substantially central projection 52, which
