Definitions

  • Hydraulic tools of the type mentioned are used, for example, in workshop operation to perform punching operations in vehicles repair work or to set rivets (see, eg, the document EP0787563 ).
  • the tool inserts are selected according to the work to be carried out, which is, for example, to punch inserts or tool plugs, which dictate the shape of the rivet heads is.
  • the hydraulic piston Upon actuation of the hydraulic tool, the hydraulic piston is displaced from its initial position in the direction of its end position due to the pressure in the hydraulic unit. The movement of the hydraulic piston is transmitted via the piston rod connected to the hydraulic piston to the arranged in the tool holder of the piston rod tool insert.
  • the present invention seeks to provide a hydraulic unit for a mobile hydraulic tool, which includes the use of tool inserts with different load capacity allows.
  • Characteristic of the hydraulic unit according to the invention is that on the hydraulic piston a pressure chamber side acting on the hydraulic piston pressure limiting, the pressure chamber with a cylinder chamber connecting pressure control valve is arranged, which is connected to the piston rod, which is a set pressure of the pressure control valve via the piston rod adjustable.
  • a pressure regulating valve is arranged on the hydraulic piston, which adjoins the pressure chamber, in which the pressure required for displacement of the hydraulic piston from the starting position in the direction of the end position, with the cylinder chamber which is adjacent to the hydraulic piston on the side opposite the pressure chamber , connects.
  • this causes, when a response pressure is exceeded, that this pressure-limiting opens and the hydraulic fluid is passed from the pressure chamber into the cylinder chamber.
  • the maximum pressure acting on the hydraulic piston and thus on the piston rod and the tool insert arranged there can thus be limited via the pressure regulating valve.
  • An adjustment of the pressure control valve is possible according to the invention via the piston rod, so that it can be adjusted comfortably via an already existing component. About the hydraulic piston can thus be in a comfortable way, the max. Set working pressure on the tool insert.
  • the configuration of the connection of the trained for receiving the tool inserts piston rod with the hydraulic piston such that the pressure control valve is adjustable via the piston rod is basically freely selectable. It is conceivable, for example, an embodiment, according to which an adjustment of the pressure control valve is effected via a rotation of the piston rod. According to a particularly advantageous embodiment of the invention, however, it is provided that the piston rod has a control rod arranged at one end in the tool holder and engageable with a tool insert, the other end is connected to the pressure control valve such that an adjustment of the control rod causes a change in the response pressure of the pressure control valve.
  • a separate, on the piston rod from the pressure control valve extending into the tool holder control rod is used to make an adjustment of the pressure valve.
  • the control rod can thus be adapted as a separate component in a special way to the pressure control valve, without requiring significant adjustments to the piston rod would be required.
  • the set pressure of the pressure control valve can be set in a simple manner.
  • a displacement of the control rod in the longitudinal axis direction causes a change in the response pressure of the pressure control valve.
  • the response pressure determined in dependence on the displacement of the control rod in the longitudinal axis direction in the direction of the pressure regulating valve or away from it.
  • a separate setting of the set pressure before the arrangement of a tool insert in the tool holder can thus be omitted, since automatically by the arrangement of the tool insert, the pressure control valve is arranged in the specific position for the respective tool insert.
  • This embodiment of the invention achieves backward compatibility, i. H. Low load limit tool inserts can also be used in a higher pressure hydraulic tool.
  • the pressure control valve such that a change in the response pressure is effected by a displacement of the control rod, can in principle be done in any way.
  • the pressure control valve has an adjustable in the longitudinal axis direction of the control rod stop element, on the one hand the control rod and on the other hand a spring element abuts the stop element at an opposite end of a stop element of the pressure control valve closing valve element, wherein the adjustable length of the spring element, the bias the set pressure determined.
  • the valve element is biased by a spring element, wherein on the bias of the set pressure of the pressure control valve is set.
  • the amount of the bias is determined by the position of the stop element, on which the spring element rests with its opposite end of the valve body.
  • An adjustment of the stop element in the direction of the valve element thus causes an increase in the bias voltage and thus increases the response pressure of the pressure control valve.
  • a displacement of the stop element in the opposite direction reduces the response pressure of the pressure control valve.
  • the response pressure of the pressure regulating valve can be determined in a simple manner via an axial displacement of the stop element, for which purpose the control rod determines the position of the stop element via its position in the longitudinal axis direction.
  • any elements can be used as spring elements, which produce a dependent of the length bias.
  • the spring element is formed by a one end of the stop element and the other end supported on the valve element helical compression spring.
  • a helical compression spring can be used in a particularly simple and cost-effective manner for setting the response pressure.
  • a displaceable in the longitudinal direction of the adjusting screw is arranged on the opposite side of the spring element of the stop element.
  • the adjusting screw limits the displaceability of the stop element due to the spring preload and thus defines the set pressure of the pressure regulating valve in the unloaded state of the stop element.
  • the adjusting screw is designed such that the control rod blockade through them can be passed, so that the stop element moved by the control rod in the direction of the spring element and thereby the response pressure can be increased.
  • the displacement of the screw can already be done once, before mounting the hydraulic unit. However, it is also possible to change the position of the adjusting screw in the mounted state by means of a suitable tool.
  • a flow channel for the hydraulic fluid reaching from the pressure chamber into the cylinder chamber in the event of an opening of the pressure regulating valve can in principle be configured in any desired manner.
  • the hydraulic piston and the control rod are designed such that after reaching the set pressure, the hydraulic fluid coaxially reaches the control rod to a cylinder chamber open overpressure channel on the hydraulic piston.
  • This embodiment of the invention allows a particularly compact and simple construction of the hydraulic piston, after an already existing for the control rod bore can be used to direct the overflowing hydraulic fluid to an overpressure channel, which opens into the cylinder chamber.
  • a determination of the position of the control rod and thus the setting of the pressure control valve can in principle be done in any way.
  • the tool inserts of different lengths according to their load capacity, so that they rest in their position arranged in the tool holder position with an end face on the control rod and adjust these in the corresponding set pressure of the pressure control valve associated position.
  • the tool insert in its length so that it does not abut the control rod in the mounted position, so that the response pressure of the pressure control valve then corresponds to the unloaded state of the control rod.
  • the tool inserts are used for this purpose and have adapted to the tool insert portion of the control rod recesses over whose extension in the longitudinal axis direction of the set pressure is adjustable.
  • the individual tools can have recesses whose length is dimensioned so that they arrange the control rod in a position in which the set pressure of the maximum load corresponds to the tool insert. The respective tool insert thus automatically sets the position of the control rod and thus the set pressure.
  • the tool insert may also have no recesses and only abut with a flat end of the control rod and so push this maximum in the direction of the pressure control valve, so that the maximum response pressure is set, which may be above the maximum hydraulic pressure can be generated , which is equivalent to a closure of the pressure control valve.
  • a recess with a length which is high in the longitudinal axis direction results in an unloaded state of the control rod, so that the response pressure predetermined by an adjusting screw is used.
  • the arrangement of the tool inserts in the tool holder is basically arbitrary. According to a particularly advantageous embodiment, however, it is provided that the tool holder has a thread for the arrangement of the tool inserts.
  • a screw-in arrangement of the tool inserts in the tool holder ensures a particularly secure and reliable positioning of the tool inserts and thus a good setting of the respective response pressures.
  • FIG. 1 a hydraulic tool 1 is shown in a sectional view. Core of the hydraulic tool 1 is a arranged on a housing body 33 hydraulic unit 2, by means of which the necessary working pressure is generated.
  • the hydraulic unit 2 in this case has a cylinder 4, within which a hydraulic piston 5 from the in Fig. 1 to 3 shown starting position in the direction of an end position is displaced.
  • a pressure chamber 22 is pressurized by means of a hydraulic fluid supplied by a connecting piece 25 connected to a cylinder cover 26. Due to the hydraulic pressure, there is a displacement of the hydraulic piston 5, which also displaces a piston rod 6 connected to the hydraulic piston 5, which at its end opposite the hydraulic piston 5 has a tool holder 12 for a tool insert designed as an anvil 11.
  • the piston rod 6 is guided in a liquid-tight manner at a guide sleeve 14 arranged in an opening 19 of the cylinder 4.
  • a guide sleeve 14 arranged in an opening 19 of the cylinder 4.
  • the position of the guide sleeve 14 by the plant of a paragraph 17 at an edge 18 of the opening 19 is fixed.
  • the position of the guide sleeve 14 is secured by a spring ring 15 which engages in a groove 16 on the guide sleeve 14.
  • a pressure control valve 3 is mounted, wherein the pressure control valve 3 is arranged with an inlet channel 37 in the pressure chamber 22.
  • the response pressure of the pressure control valve 3 is determined by a helical compression spring 30 which abuts one end of the inlet channel 37 closing valve element 29 and the other end on a stop element 31 which is axially displaceable in the direction of the helical compression spring 30 and away from it.
  • the stop element 31 On the position of the stop element 31 can thus be the bias of the helical compression spring 30 and thus determine the set pressure of the pressure control valve 3. With its helical compression spring 30 opposite side of the stop element 31 abuts on a screw 32, which thus determines the set pressure in the unloaded state of the stop member 31.
  • the adjusting screw 32 is adjustable in the direction of the helical compression spring 30 or away from it.
  • the piston rod 6 For displacement of the stop element 31 from its position in which this rests on the adjusting screw 32, the piston rod 6 has an axially extending to this control rod 7 which rests with an end portion 10 on the stop element 31. An axial displacement of the control rod 7 in the direction of the stop element 31 thus causes its adjustment, in which the helical compression spring 30th compressed and so the response pressure is increased.
  • the tool insert 11 has a recess 13 into which the tool insert portion 8 of the control rod 7 engages.
  • the longitudinal extent of the recess 13 is such that the control rod 7 is not displaced in the direction of the pressure control valve 3, so that this has set by the set screw 32 set pressure.
  • the tool insert 11a In the in the FIGS. 4 . 4a and 4b illustrated embodiment of the hydraulic unit 2, the tool insert 11a, however, no recess 13, but lies with its the control rod 7 facing end side of this and moves it in the mounted position in the direction of the pressure control valve 3, so that the stop member 31 displaced and the helical compression spring 30 compressed and thus the response pressure is increased.
  • valve element 29 Upon reaching the set pressure, the valve element 29 is displaced in the direction of the helical compression spring 30, so that hydraulic fluid from the pressure chamber 22 can flow past the valve element 29 through the inlet channel arranged in the valve body 28.
  • the hydraulic fluid then passes coaxially to the valve portion 9 of the control rod 7 to an overpressure channel 20, which opens into a cylinder chamber 21. From there, the hydraulic fluid passes through the return lines 23a, 23b to the connecting piece 24 which in turn is connected to a hydraulic line.
  • the pressure control valve 3 is fixed by screwing the valve body 28 in a valve body receptacle 36 on the hydraulic piston 5 and in a valve body receptacle 27 on the piston rod 6 in its position.
  • the piston rod 6 in turn is screwed with a connecting portion 34 in the receiving portion 35 of the hydraulic piston 5.
  • a guide ring 38 in the valve body receiving 27 serves to support the valve portion 9 of the control rod.
