Definitions

  • the present invention relates to an electrically operated pressing tool for connecting tubular workpieces with a fork-shaped receptacle, held in this recording by means of a connecting pin interchangeable clamping pliers and a controlled electric drive motor for actuating the clamping pliers, wherein a powered by the electric drive motor via a reduction gear spindle is present is in operative connection with the clamp.
  • Portable, electrically operated pressing tools of the type mentioned are used for pressing of coupling elements, such as press sleeves, press fittings, pipe sleeves, telescoped pipe sections and the like.
  • the pressing tools have a clamping pliers with clamping jaws, which form a pressing space for receiving the coupling element to be pressed.
  • the necessary for the compression Compressive pressure was initially generated by an electric motor connected to the net via an axially forward and backward spindle which acts on a two-roller yoke, the rollers moving the jaws of the clamp.
  • Another advantage of the hydraulically operated pressing tools is the fact that battery-powered electric motors can be used, so you can work independently from the grid. Thanks to the hydraulic drive, it was also possible to use battery-operated electric motors that initially had a relatively low torque.
  • a spindle-type pressing tool is known in which the pressure to be built up is electronically monitored by monitoring the rotational speed of the electric motor and guiding and controlling it with a predetermined profile within a certain range.
  • This characteristic of the compression is essentially dependent on the size, shape and material properties of the coupling elements and thus allows the generation of a compression process that takes place depending on pressure and time.
  • the present invention has set itself the task of changing the design of a pressing tool so that it can be smaller, cheaper and easier to build, without losing the safety aspects.
  • the pressing tool 0 is an electromechanical device, which is realized here as a battery-powered device.
  • the pressing tool 0 has a press tool unit 2 on which a handle 1 is formed.
  • a battery housing 6 is formed as a removable part.
  • a fork-shaped receptacle 3 can be seen.
  • the clamping pliers 4 is held. This is kept secured by means of a monitored securing bolt 5 in the receptacle 3.
  • a trigger switch 8 is available for the operation of the device.
  • On a display unit 7, the functional state of the pressing tool is displayed, while the user is informed by means of LEDs 9, whether a pressing could be performed correctly or not.
  • the electric drive motor 10 acts on a shaft 13.
  • the shaft 13 drives a threaded spindle 14, on which a spindle nut 16 runs and displaces a roller feed element 15, which is moved translationally into the fork-shaped receptacle 3.
  • the electric motor 10 can be designed as a DC or AC motor. Preferably, one will choose a lower mass and high torque electric motor. Such motors are available in the market in various embodiments.
  • the output of the electric motor 10 takes place on a reduction gear 11. This is a completely traditional gear, which is connected via an output 12 with a shaft 13.
  • the connection between the output 12 and the shaft 13 can be realized as a simple, virtually play-free plug connection.
  • the shaft 13 is preferably made in one piece and axially aligned with a threaded spindle 14.
  • the threaded spindle 14 is provided with a suitable for the transmission of large forces trapezoidal thread.
  • the spindle housing 21 which forms part of the housing of the functional unit 2 is delimited in the direction of the clamping tongs 4 by the fork-shaped receptacle 3, the spindle housing 21 is closed by a housing plate 20 on the motor side.
  • the shaft 13 passes through this housing plate 20 and is mounted in the housing plate 20 itself in a radial bearing 19.
  • the shaft 13 is limited to the spindle 14 through a pressure flange 17.
  • a pressure ring 27 which acts directly or indirectly on a force or pressure sensor 25. The simplest way of doing this would be with annular force or pressure sensors available on the market, which would be arranged between the pressure ring 27 and the housing plate 20.
  • a lever 26 and a counter-pressure ring 28 are provided between the pressure ring 27 and the housing plate 20.
  • the relative position of the lever 26, the pressure ring 27 and the counter-pressure ring 28 is rotatably secured by a pin 29, wherein the pin 29 engages in the housing plate 20.
  • balls 24 are inserted, which allow a pivoting movement of the lever 26.
  • the electric motor 10 drives the shaft 13 and the threaded spindle 14 via the reduction gear 11, whereby the spindle nut 16 slides forward in the direction of the fork-shaped receptacle and thus the roller feed element with the rollers 30 in the figure to the right emotional.
  • the rollers 30 run on the cheeks of the jaw 40 of the clamping jaw 4 and close it.
  • the reaction force leads to an increased pressure of the spindle 14 and the associated pressure flange 17 on the thrust bearing 18, which passes this pressure on the pressure ring 27.
  • the entire pressure is finally passed to the rigid housing plate 20.
  • the pressure monitoring realized here ensures that the connecting elements are pressed with the required pressure. Of course, this alone is not enough.
  • the complete closing of the clamping tongs is monitored.
  • Such monitoring can be done by appropriate sensors on the clamp itself or it can be a way monitoring.
  • the displacement path of the roller feed element 15 can be monitored by means of corresponding sensors in this case.
  • this sensor not shown here passes a corresponding information to the controller 22, wherein a failure to reach the required path leads to a corresponding error message.
