Definitions

  • hand-held pressing devices which consist of a drive device and an end attached via a coupling adapted to the particular application pressing tool.
  • the drive device is formed electrohydraulically in the present type of such pressing devices.
  • a mains or battery-powered, electric drive motor drives a hydraulic pump, which may be designed as a piston or gear pump.
  • the hydraulic pump acts on an actuating device in the form of a hydraulic motor.
  • such a hydraulic motor is designed as a piston-cylinder unit with a hydraulic piston arranged in a hydraulic piston whose piston rod acts on the pressing tool. During movement of the piston rod, one or more pressing jaws are moved in the pressing tool in the pressing direction.
  • To the hydraulic pump includes a hydraulic reservoir, from which the hydraulic pump sucks hydraulic fluid through its suction side and promotes via its pressure side in the pressure chamber of the piston-cylinder unit.
  • the hydraulic system also includes a connection between the pressure side of the hydraulic motor and the hydraulic reservoir.
  • a pressure relief valve is arranged, which is initially closed during the pressing process and only when reaching a certain maximum pressure, also called cut-off pressure, opens to the hydraulic reservoir.
  • the cut-off pressure is designed so high that in a normal pressing operation opening only takes place when the pressing process is completed, so that the pressing tool has reached its final pressing position.
  • the pressure relief valve can not always open. It can be mechanically blocked in such a way that opening does not succeed. If there is a blockage in the pressure area of the hydraulic system, the manually operated opening of the pressure relief valve is of no use. In both cases, the possibility of manual opening of the pressure relief valve can not prevent that during the pressing process, a well above the cut-off pressure hydraulic pressure builds up, which leads to an overload of parts of the pressing device. This can result in the crimping tool breaking and the broken pieces flying away at high speed and thereby endanger persons, in particular the operator.
  • the invention has for its object to make a drive device for a pressing device of the type described above so that the drive device or the pressing device is better protected against overloading.
  • the basic idea of the invention is thus to provide an emergency valve, which is assigned to the pressure relief valve and only then opens when the overpressure valve does not lead to a pressure relief when the cutoff pressure is reached, for example because a blockage is present or the pressure relief valve is blocked.
  • the emergency valve is set so that the emergency pressure is at least equal to the cut-off. However, it can also be above it, but should still be so low that no overloading of parts of the pressing device takes place. With the help of the emergency valve so the safety of the drive device and thus also the pressing device is substantially increased.
  • the emergency valve may be formed, for example, as a spring-loaded needle valve. This does not exclude that other types of valves, such as a ball valve, comes into question. It should be designed as a check valve.
  • the emergency valve may be arranged in series with the pressure relief valve, for example between pressure relief valve and hydraulic reservoir with its own connection to the hydraulic reservoir. However, a parallel arrangement of pressure relief valve and emergency valve is preferred.
  • the emergency valve is connected via a separate hydraulic system from the hydraulic channel with the pressure chamber of the hydraulic motor. In this way Blockages in the hydraulic system do not affect the function of the emergency valve. This applies a fortiori when the emergency valve is connected to the hydraulic reservoir via a hydraulic channel which is separate from the hydraulic system, so that the emergency valve is not part of the hydraulic system between hydraulic motor, hydraulic pump and hydraulic reservoir. This does not exclude that the emergency valve is installed at a suitable location in the existing hydraulic system.
  • the emergency valve is coupled to a manual operating device, via which the emergency valve can be opened from the outside.
  • a manual operating device via which the emergency valve can be opened from the outside.
  • the manual actuating device has a manual actuating element which projects into the hydraulic reservoir and ends there, wherein the hydraulic reservoir in the region of the manual actuating element has an outer wall of the drive device forms and the outer wall, at least there, ie in the region of the manual actuating element, is designed so elastic that the manual actuating element is movable by acting on the outer wall, for example by pressure, in the opening direction.
  • This training has the advantage that the manual override is completely within the overall hydraulic system, so not - as in the prior art - must be sealed to the outside.
  • the risk of accidental operation is significantly reduced. This does not preclude the hand-operated element from sticking out of the drive device, as happens in the prior art.
  • the manual actuating element can be designed, for example, as an actuating tappet which extends transversely to the longitudinal axis of the pressing device, while the emergency valve has a valve body which extends transversely to the actuating tappet.
  • actuating tappet and valve body may be coupled via an inclined surface, via which the movement of the actuating tappet is converted in its axial direction in an axial movement of the valve body in its opening direction when it is acted upon.
  • both actuating tappet and valve body are each acted upon by a spring, both of which act against the opening direction.
  • the hydraulic reservoir in a conventional manner has an outer wall which surrounds the drive device at least partially in the form of a jacket (see DE 203 03 877 U1 ).
  • the outer wall of the hydraulic reservoir can then be formed by a flexible, in particular elastomeric hose.
  • This design of the hydraulic reservoir is particularly suitable for the design of the manual override, in which the manual control element protrudes into the hydraulic reservoir and ends there.
  • the hydraulic motor can be designed in a manner known per se as a piston-cylinder unit with a hydraulic cylinder and a hydraulic piston.
  • the pressure relief valve in the hydraulic piston and / or in a piston rod of the hydraulic piston is arranged (see. DE 203 03 877 U1 and DE 20 2004 000 215 U1 ).
  • a control valve may also be provided in addition, as it DE 20 2004 000 215 U1 can be taken, the content of which is hereby made the disclosure of the present application.
  • the illustrated pressing apparatus 1 has an elongated drive unit 2, at one end of which a pressing tool 3 is coupled, which is suitable for the compression of press fittings, which serve to connect pipe ends.
  • the drive unit 2 has at the opposite end of the pressing tool 3, an electric motor 4, whose output shaft 5 is coupled to a pump shaft 6 of a total of 7 designated hydraulic pump.
  • the pump shaft 6 is guided in the hydraulic pump 7 in two bearings 8, 9 and has between the two bearings an eccentric 10 which acts via a needle bearing 11 on a radially displaceably guided pump piston 12.
  • the pump piston 12 is moved radially back and forth.
  • the housing of the hydraulic pump 7 is surrounded on the outside by an elastomeric hose 13 which encloses a hydraulic reservoir 14 between them and the outside of the hydraulic pump 7 in a liquid-tight manner.
  • the ends of the tube 13 engage in grooves 15, 16 and are held there from the outside by pushed-over fixing rings 17, 18 in position.
  • the hydraulic pump 7 is flanged in the axial direction on the side facing away from the electric motor 4 to a hydraulic motor in the form of a piston-cylinder unit 19.
  • the piston-cylinder unit 19 has a hydraulic cylinder 20 which is closed on the hydraulic pump side with an end plate 21.
  • a hydraulic piston 22 is guided displaceably. He divides the interior of the hydraulic cylinder 20 in an end plate-side pressure chamber 23 and a rear space 24 a.
  • the hydraulic piston 22 is seated on a piston rod 25 which extends on the side facing away from the end plate 21 in the direction of the pressing tool 3.
  • a hat-shaped sealing element 26 is inserted, which rests on the inside of the piston rod 25 and thus seals the rear space 24.
  • the sealing element 26 also serves to support a piston spring 25 surrounding the coil spring 27, which is supported at the other end on the side remote from the pressure chamber 23 of the hydraulic piston 22.
  • the coil spring 27 is formed as a compression spring and consequently endeavors to move the hydraulic piston 22 in the direction of the end plate 21.
  • the hydraulic piston 22 remote from the end of the Kolbentsange 25 is rigidly connected outside of the rear space 24 with a spreader 28.
  • the spreader 28 has a bearing body 29, are mounted on the two spreader rollers 30, 31 transversely to the axis of the pressing device 1 side by side and freely rotatable in mutual contact.
  • a holder 32 Attached to the back-room-side end of the hydraulic cylinder 20 is a holder 32 which forms two coupling straps 33, 34, which extend in the axial direction of the pressing device 1.
  • the coupling tabs 33, 34 have such a distance from each other that the spreader 28 can move between them.
  • end coupling bores are provided which extend transversely to the longitudinal axis of the pressing device 1 and are aligned. In the area of these coupling bores and between the coupling tabs 33, 34 in a manner known per se (cf., for example FIG. 1 of the EP 1 157 786 A2 or FIG. 1 of the DE 20 2004 000 215 U1 ) two mutually parallel pressing tool tabs, of which in FIG.
  • Both press tool tabs 35 also have coupling holes that are aligned with each other and have the same diameter as the coupling holes in the coupling tabs 33, 34.
  • the connection between the coupling tabs 33, 34 and thus the drive unit 2 is made by a coupling pin 36 through inserted through all four coupling holes and locked for the purpose of its positional fixation is. In this way, the pressing tool 3 is pivotally connected to the drive unit 2.
  • the press tool flaps 35 are of identical construction and are arranged congruently and at a distance. They are connected to each other via two hinge pins 37, 38. In the intermediate space between the press tool tabs 35, mirror-shaped press jaw levers 39, 40 are mounted pivotably on the hinge pins 37, 38.
  • the pressing jaw levers 39, 40 form semicircular pressing jaws 41, 42 at their outer ends, which in the illustrated, closed state of the pressing tool 3 enclose a pressing space 43.
  • a compression spring 44 ensures that the pressing jaw lever 39, 40 take the illustrated closed final pressing position in the idle state.
  • the pressing jaw levers 39, 40 form drive surfaces 45, 46, which interact with the cylindrical surfaces of the spreading rollers 30, 31 during the pressing process.
  • the hydraulic pump 7, ie their limited by the pump piston 12 pressure chamber has not shown here hydraulic channels on the one hand connection to the hydraulic reservoir 14 and the other to the pressure chamber 23 in the piston-cylinder unit 19.
  • a check valve in the hydraulic line to the hydraulic reservoir 14 ensures in that the pump piston 12 aspirates hydraulic oil from the hydraulic reservoir 14 when moving in one direction and the aspirated when moving in the other direction Hydraulic oil transported into the pressure chamber 23.
  • the hydraulic piston 22 and thus also the piston rod 25 and the spreader 28 connected thereto are moved in the direction of the pressing tool 3.
  • a pressure relief valve 47 is formed in the form of a needle valve.
  • the hydraulic piston 22 has a pressure opening 23 open valve opening 48, which serves as a valve seat for a valve body 49 on the inside. This is loaded in the direction of the valve opening 48 by means of a pressure acting on the rear side of the valve body 49 compression spring 50.
  • the compression spring 50 is designed so that it allows a lifting of the valve body 49 only at a certain cut-off pressure in the Druchraum 23.
  • the valve body 49 defines a valve chamber 51, which has a connection to the rear space 24 via a hydraulic channel, not shown here. This in turn is connected via a hydraulic channel, also not shown, with the hydraulic reservoir 14. All above-described hydraulic channels form a total of a hydraulic system. -
  • an emergency valve 52 which is also designed as a needle valve. It has a connection channel 53 direct connection to the pressure chamber 23.
  • the connecting channel 53 narrows into a valve seat insert 54, the inside a valve seat forms, on which a valve needle 55 sealingly abuts.
  • the valve needle 55 is loaded with a compression spring 56.
  • This compression spring 56 is designed so that the valve needle 55 only lifts off from the valve seat insert 54 and thus the emergency valve 52 opens when the pressure in the pressure chamber 23 has reached a value which is at least equal to the cut-off, at which the pressure relief valve 47 at normal function opens, but can also lie about it.
  • the valve chamber of the emergency valve 52 has a channel, not shown here, connection to the hydraulic reservoir 14, so that the hydraulic fluid in the pressure chamber 23 can flow into the hydraulic reservoir 14 when opening the emergency valve 50.
  • a manual override device 57 is provided, with the aid of which it is possible to effect an opening of the emergency valve 52 by external action.
  • the manual actuation device 57 has an actuation tappet 58, which is displaceably guided transversely to the axial extension of the valve needle 55 and ends near the tube 13 within the hydraulic reservoir 14.
  • actuation tappet 58 is displaceably guided transversely to the axial extension of the valve needle 55 and ends near the tube 13 within the hydraulic reservoir 14.
  • a transverse pin 60 passing through the actuating tappet 58 prevents rotation of the actuating tappet 58 and forms a stop for the starting position.
  • valve needle 55 At the valve needle end of the actuating plunger 58 is penetrated by the valve needle 55 and forms there Sloping surface 61, on which abuts a contact surface 62 of the valve needle 55. Due to this coupling, the valve needle 55 is lifted from the valve seat insert 54 against the action of the compression spring 56 when the actuating plunger 58 is moved by applying pressure to the hose 13 in the direction of the valve needle 55. Independently of this, the coupling between actuation tappet 58 and valve needle 55 allows the valve needle 55 to move freely in the opening direction, so that the actuation tappet 58 has no influence on the automatic opening behavior of the emergency valve 52.
  • the pressing device 1 is attached to the press fitting after previously compressed the two pressing jaw lever 39, 40 by hand to the spreader 28 adjacent ends against the action of the compression spring 44 and thus the pressing jaws 44 are removed from each other so that the end a mouth-like opening results.
  • the pressing tool 3 can then be applied radially to the intended location of the press fitting, wherein the pressing jaws 41, 42 initially come to rest on the press fitting and accordingly the drive surfaces 45, 46 are approximated to each other.
  • the electric motor 4 is set in motion with the result that the hydraulic pump 7 sucks hydraulic fluid from the hydraulic reservoir 14 and promotes into the pressure chamber 23.
  • the lateral surfaces of the spreading rollers 30, 31 on the drive surfaces 45, 46 of the pressing jaw lever 39, 40 to the plant and spread them apart gradually.
  • the pressing jaws 41, 42 approach each other and thus ensure a compression of the press fitting radially inward. This continues until the pressing jaws 41, 42 come into mutual contact, so reach their final pressing position. In the process, the pressure in the pressure space 23 increases successively.
  • the pressure in the pressure chamber 23 increases as the electric motor 4 and thus the hydraulic pump 7 continues beyond the cut-off pressure. If the pressure then reaches the emergency pressure, the emergency valve 52 opens by lifting the valve needle 55 from the valve seat insert 54 and then leads to a Drukkentlastung the pressure chamber 23, because the hydraulic oil in the pressure chamber 23 now via the connecting channel 53 and the connection of the emergency valve, not shown here 52 can flow to the hydraulic reservoir 14. About the manual override 57 can be effected at any time and independent of the pressure in the pressure chamber 23, a pressure relief throughout the hydraulic system.
