Definitions

  • the invention relates to a pressing tool according to the preamble of claim 1 and a pressing process according to The preamble of claims 3 or 4.
  • the pressing tools according to The state of the art can be used with many different, interchangeable Press tongs are used.
  • the different Crimping pliers are for pressing copper and steel fittings or for connecting plastic pipes with different ones Diameters formed.
  • Crimping tools have been used for attaching the various Crimping pliers have a fork-shaped connecting part in which the Press pliers inserted and with a fastening bolt on Press tool to be attached.
  • the different pressing tongs therefore have a hole in their connecting element, through which the fastening bolt is inserted.
  • the connector also has a hole in which the fastening bolt is recorded and secured. The fastening bolt must fully inserted into the hole in the connector be sure to ensure that the press tool is working properly works. It keeps coming back for various reasons before that the mounting bolt was not inserted properly is what has already led to accidents.
  • EP-0941813-A1 is a pressing tool known to prevent such accidents Locking control of the fastening bolt during operation performs. As long as the fastening bolt is not working properly is secured, a warning signal is triggered. It there will also be a presence check regarding the pressing tongs performed. The disadvantage is that if there is no or incorrectly inserted crimping pliers not the pressing process as such is ended.
  • the invention is based on the object of an improvement the safety of such a press tool. In addition only then should a pressing process of the pressing tool be triggered can be ensured if the presence of crimping tongs is.
  • a Press process feasible, in which the pressing with all insertable pressing tongs can be carried out safely.
  • the pressing process are initialization steps after switching on the press tool or tests provided.
  • a presence check takes place, which detects whether a pressing tongs is inserted or not. If there is no pressing tongs, an acoustic and / or optical warning signal triggered and then again the Attendance check carried out. Is after a delay time still no pressing tongs used or only poor inserted, the pressing tool is switched off or the pressing process cannot be triggered. Another one To initiate the pressing process, pressing tongs must be inserted into the pressing tool introduced and by means of the fastening bolt on Press tool to be attached.
  • a locking control is carried out during the pressing process.
  • the press tool shows how to carry out the locking check at least one non-contact locking sensor on. If the mounting bolt is not locked, or in the securing position, this is done by the locking sensor recorded and at least with an acoustic and / or optical warning signal is displayed. If necessary, the Locking control repeated until the fastening bolt is locked or secured. Possibly after one Delay time given to the operator, the lock to carry out the fastening bolt properly, the pressing tool is ready for triggering a pressing process.
  • 1a shows a fork-shaped connecting part 7 of a pressing tool
  • 1b shows a section thereof, with a piston rod 6, press rollers 28 and a guide block 29 which in a straight guide 30 is guided.
  • the straight guide 30 is on attached to a cylinder part 5 and has in the region of the fork-shaped Connection part 7 has a bore 31 for receiving a Fastening bolt 50 with which crimping pliers 51 are fastened becomes.
  • the pressing tongs 51 consist of a fastening part 51c, that is firmly connected to a connecting element 51d, and in the two press jaws 51a and 51b each around an axis of rotation 9a and 9b are pivotally mounted, which axes of rotation 9a and 9b perpendicular step out of the image plane.
  • the press jaws 51a and 51b have Actuating surfaces 8a and 8b that 44 (see Figure 2) rest on the press rollers 28.
  • the operating areas are designed so that those moving forward Press rollers 28, the press jaws 51a and 51b by means of pivoting movements about their axes of rotation 9a and 9b in the area of one Move pressing fittings 32a together, the fitting 32a together with the pipe ends to be connected in one Opening 32 of the pressing tongs 51 is inserted.
  • a press tongs presence control 45 (see FIG. 2) enable, preferably a non-contact measuring presence sensor 52 arranged in the straight guide 30 so that it makes a field characteristic determinable, which with existing and missing pressing tongs 51 can be clearly distinguished.
  • a presence magnet on the crimping pliers 51 be provided, which of a Hall sensor as a presence sensor 52 of the pressing tool can be detected.
  • an inductive sensor is used to determine the presence any pressing pliers 51 made of metal does, even if there is no presence magnet in the pressing tongs 51 is provided.
  • a touch-sensitive one can also be used Sensor, such as a pressure sensor, or a mechanical switch can be used as a presence sensor 52.
  • the fastening bolt 50 has a transverse to the bolt axis Handle 50a on when inserting the fastening bolt 50 is aligned in a first direction.
  • a longitudinal bolt groove 50b takes a guide pin 53 on when the fastening bolt is fully inserted 50 lies in an annular groove 50d, so that the fastening bolt 50 rotatable by 180 ° into a locking position is.
  • a locking control 47 (see FIG. 2) provides that the mounting bolt 50 is in the locked position is controllable.
  • the handle 50a is preferably for this purpose provided with a locking magnet 50c, which in the locked State or in the locking position to a locking Hall sensor 54 in the pressing tool. If the Locking Hall sensor 54 detects the locking magnet 50c, the fastening bolt 50 is in the locking position. If the control of the locking is negative, a warning signal is triggered, without necessarily the Interrupt the start process of the pressing tool. It understands of course, that instead of the Hall sensor, for example an inductive sensor can be used.
  • Fig. 2 illustrates a pressing method for pressing sleeve-shaped fittings 32a with a pressing tool that over a piston rod 6 and a transmission device the clamping movement actuated at least one press jaw 51a or 51b (see Figure 1).
  • the pressing tool is activated by an on / off switch switched on with a switch-on step 41. After that are in an initialization step 42 self, start and Service tests carried out.
  • Pressing process 44 together with the detection of operating parameters Can be triggered in a repeatable second Step are detected whether the press tool is ready for Triggering a pressing process 44.
  • a press tongs presence check 45 is carried out, until a crimping tool 51 (Fig.1) is inserted.
  • an acoustic and / or optical notification signal 45a triggered or maintained. If after a delay time still none Crimping pliers 51 is used, the pressing tool by means of a first time delay device 45b are switched off. If a crimping tool 51 is inserted, after a Delay time mapping detection 46 is performed, such as in the publication EP 0941813-A1 of the crimping pliers 51 used has a piston position range value assign. If there is a missing assignment information a standard range assignment 46a is performed.
  • a pressing process 44 is preferably a locking control 47 carried out at an unsecured Fastening bolts to trigger at least one warning signal 47a.
  • the pressing tool is ready to trigger one Pressing process 44. Is the fastening bolt 50 (Fig.1) not properly locked, readiness for the pressing process 44 only after a delay time by means of a second Time delay device 47b released to the operator the possibility of giving the fastening bolt 50 to lock.
  • a rest time control 43a detects whether the device is already during a predetermined maximum rest time switched on without pressing 44 is. If the maximum rest period has not yet been reached, the device goes through the second step or the control steps again 45-47. If the maximum rest period is reached, the pressing tool is switched off. Before another press 44 can be triggered, the control steps must again 45-47 can be performed.
