Definitions
- the invention relates to a hand-held pressing device for connecting two workpieces.
- the pressing device according to the invention is suitable for connecting a pipe to a press fitting by pressing.
- the invention relates hand-held pressing tools for pressing cable lugs.
- Such hand-held pressing devices have a pressing tool with several pressing jaws.
- the press jaws enclose the press fitting inserted over the pipe in a press tool for pipe connections. By closing the pressing jaws, deformation or compression of the press fitting and of the tube takes place.
- pressing tools for cable lugs these are pressed by closing of pressing jaws, the lug is arranged between at least two pressing jaws.
- One of the press jaws can be fixed here.
- the pressing tool is connected to a usually electro-hydraulic or electromechanical conversion device.
- the conversion device is usually driven by an electric motor with the interposition of a transmission.
- a hydraulic conversion device has a hydraulic pump in which it is Usually is a piston pump or a gear pump. The pump is driven by a brush motor.
- the pumps used through which a high torque must be generated, require a design-related relatively low drive speed of usually 2,000 to 5,000 revolutions per minute.
- a reduction gear is interposed between the motor and the pump.
- a working piston is displaced by the hydraulic pumping medium conveyed by the pump.
- the bayskoiben is connected to the pressing jaws, so that high pressing forces can be transmitted to the pressing jaws on the working piston.
- the pressure chamber provided for actuating the working piston is opened by a valve, which is usually designed as a needle valve, so that a sudden pressure reduction takes place in the pressure chamber.
- the pressure reduction leads to a speed increase of the pump, which is detected by a speed sensor and leads to an automatic shutdown of the electric motor.
- a return spring is then used to push back the working piston and thus open the pressing jaws.
- Such hand-held pressing devices must be maintained at regular intervals. Investigations have shown that the maintenance interval determining component is the brush motor. Due to the frequent start-up under load and due to the provision of stop functions, in which a short circuit is generated via the brush, the brushes of the brush motor are exposed to very heavy wear.
- the object of the invention is to provide a hand-held pressing device, are realized in the longer maintenance intervals.
- the hand-held pressing device according to the invention for connecting a pipe to a press fitting by pressing has a pressing tool with several pressing jaws.
- the pressing tool is driven by an electric motor with the interposition of a conversion device.
- the transformation means in particular, is an electrohydraulic or electromechanical conversion device.
- the electric motor is a brushless electric motor.
- a brushless electric motor has the considerable advantage over the brush motor used in known pressing tools that no wear-resistant brushes are provided. By using a brushless electric motor can be omitted due to the heavy loads with high wear brushes. This makes it possible to significantly extend the maintenance cycles.
- the number of compressions that can be carried out between two maintenance operations can in particular be at least doubled or even tripled.
- a brushless electric motor according to the invention has the advantage that the maintenance costs are reduced since an exchange of the brushes or the entire brush motor is not required.
- the electric motor is an external or internal rotor motor.
- the electric motor is a brushless external rotor motor.
- External rotor motors have the advantage over brushless internal rotor motors that they rotate slower and have a higher torque with the same overall dimension.
- a seven-pole external rotor motor has a stator with twelve slots, each second slot being wound. It follows that the field rotates by 60 ° when changing the phase.
- the bell surrounding the stator or the external rotor in this example has fourteen magnets or seven pole pairs, which are arranged distributed over 360 °.
- the external rotor moves Drma! slower than the field, so that the outer rotor only rotates by 8.57 ° when the field moves 60 °.
- a low speed is realized in an external rotor.
- the brushless electric motor is directly connected to the converter.
- a mandatory when using brushes motors reduction gear can be omitted in this preferred embodiment of the invention.
- the output shaft of the electric motor is directly connected to the hydraulic pump, ie to the drive shaft of the hydraulic pump. Due to the possible omission of the transmission in this embodiment, the costs can be reduced. In particular, however, the required space can be significantly reduced.
- a particular advantage of using the brushless motor by omitting or greatly simplifying a reduction gear is that the efficiency can be significantly improved. In particular, due to the friction occurring in the transmission losses occur which can be greatly reduced by a great simplification or even by completely omitting the transmission.
- the transmission By omitting the transmission, which is possible when using a brushless motor, an increase in the efficiency of in particular over 20% and particularly preferably over 25% can be achieved.
- This has the advantage that the operating time can be extended considerably when using the same battery or, for the same operating time, a smaller and thus lighter battery can be used.
- Another advantage of the simplification or omission of the transmission is that a considerably lower noise is generated. Also, the vibrations occurring and the heating caused are less.
- the output shaft of the electric motor is arranged such that it is coaxial with the drive shaft of the hydraulic pump. As a result, a simple connection of the shafts can be realized in a small space.
- a particular advantage of the use of a brushless electric motor for operating the pressing device is that additional functions can be implemented in a simple manner by means of a brushless electric motor or the control device of the brushless electric motor.
- a controller connected to or integrated into the electric motor not only is the control of the speed required to produce a desired torque or a desired pressing force, but also a determination of the current speed.
- the voltage induced in the windings can be used to draw conclusions about the engine speed. This makes it possible to detect in a simple manner that the engine speed increases. A sudden increase in the engine speed occurs when opening the Druckventiis, ie as soon as the required pressing force is reached.
- This speed increase of the motor can be determined in a simple manner via the control device and used to switch off the electric motor.
- the speed sensor required in known pressing devices which is absolutely necessary for determining the speed increase when opening the valve, can be eliminated by the inventive use of a brush-free electric motor.
- the manufacturing cost can be reduced.
- this has the advantage that an important for the function of the pressing device component is replaced by the control device of the engine and thereby a much more reliable speed determination is carried out. Failure of the speed sensor, which can lead to significant damage to the pressing tool, can no longer occur.
- a determination or calculation of the engine torque and / or the pressing force generated by the pressing jaws takes place directly via the parameters of the brushless electric motor.
- the valve which opens the pressure chamber in conventional pressing devices can be omitted or at least greatly simplified.
- the valve, which is opened in known pressing devices upon reaching the pressing force can be simplified in this preferred embodiment, at least in such a way that it is only an emergency valve, which avoids damaging the pressing device in the event of failure of the control device.
- Another advantage of using a brushless electric motor, in particular in connection with the already existing or connected to the electric motor control device, is that upon reaching the set pressing force or when errors occur, the motor can be decelerated by appropriate control commands or by software , The high wear occurring in brush motors, which occurs when braking the motor via the generated short circuit, can thus be avoided.
- an adjusting device is provided.
- pressing parameters can be entered in a simple manner, for example via keys and a display. These are transmitted to the control device of the electric motor, so that an immediate simple control of the electric motor and thus the entire pressing device is possible.
- the desired pressing force is input only via the adjusting device.
- the construction of the pressing device is considerably simplified. Furthermore, eliminates mechanical components that, in particular due to the high forces that occur, possibly damaged or at least maintenance-intensive.
- the adjusting device it is possible, for example via the adjusting device to enter the type of pressing tool used.
- a complex adaptation of the pressing device to the pressing tool is no longer necessary. It is only necessary to enter, for example, a code of the pressing tool.
- automatic recognition of the type of pressing tool by the pressing device takes place. This can be done by an identification of the pressing tool, which is detected in particular automatically by the control device. The user can thus replace the pressing tool and does not have to take care that the corresponding pressing parameters are adjusted. As a result, it is avoided, for example, that the maximum permissible pressing force for a particular pressing tool is exceeded.
- the signal output device can be signaled in a simple way the completion of the compression. Also, the occurrence of disturbances or the need to perform maintenance can be signaled by the signal output device.
- the signal output device may be an acoustic and / or tactile (vibration) signal output device. The particular acoustic signal output can in this case be realized directly by the control device.
- the signal output device may also have a display.
- the hand-held pressing device is operated in a preferred embodiment such that the control device connected to the electric motor, as described above, is used for determining the rotational speed and / or the torque and / or other pressing parameters.
- the controller may also be used to control a signal output device.

- the hand-held pressing device for connecting pipes by means of a press fitting by compression has a brush-free electric motor 10 whose output shaft 12 is connected to an eccentric 14. About the eccentric 14, a pump piston 16 is operated. Further, the brushless electric motor 10 is not for power supply with one represented rechargeable battery, such as a battery or a power supply or the network connected.
- a control valve 18 Via a control valve 18, the hydraulic fluid is supplied to a chamber 20.
- a working piston 22 By pumping the hydraulic fluid into the chamber 20, a working piston 22 is moved to the left in the drawing. The left in the figure, the end of the working piston 22 is connected to the pressing jaws 24 of the pressing tool 26 -.
- the pressing jaws 24 enclose the pipe, not shown, and surrounding the pipe press fitting, which are arranged in a recess 25.
- the illustrated pressing device thus has three main components, the pressing tool 26, a converting device 28 and the electric motor 10.
- a needle valve 30 is provided which opens the chamber 20 upon reaching the pressing force, so that the pressure in the chamber abruptly decreases. Due to this pressure decrease in the chamber 20, the engine speed increases significantly. This speed increase is detected by a control device 32 which is connected to the brushless electric motor 10, and leads to the switching off of the electric motor 10. As soon as the electric motor 10 is switched off, the working piston 22 is returned by the spring 34, as shown in FIG Starting position pushed back.
- control device 32 can be connected to an adjusting device 34, which is provided in particular on the housing, not shown, of the pressing device.
- the adjusting device 34 which has, for example, a display 36 and input keys 38, pump parameters, pressing forces, etc. can be preselected.
- the inventively provided brushless electric motor can be used as a signal output device. This can be an acoustic signal output, a tactile signal output, such as the generation of vibrations, or else an optical signal output via a display.
- the already existing display 36 of the adjusting device can be used for signal output.
- a pressing device is a pressing device for cable lugs (Fig. 2).
- the pressing device for cable lugs shown schematically in Fig. 2 is shown in a non-sectional side view, the operation corresponds to that of the pressing tool described with reference to FIG.
- a brushless electric motor 10 is also provided according to the invention, which is also connected to an eccentric.
- Within a housing 41 thus the same components, as shown in FIG. 1 can be seen, arranged. Only the substantially cylindrical intermediate part 42 (FIG. 1) provided for receiving the pressing jaws is dispensed with. Instead, pressing jaws 44 (FIG. 2) are connected to the working piston 22 (FIG. 1).
- the pressing jaws 44 are arranged within a pressing jaw head 46.
- the pressing jaw head 46 has an opening 48 into which the crimping cable lug is inserted.
