Definitions

  • the drive piston which is hydraulically adjustable in the hydraulic tool housing between the starting position and the end position, serves to drive a tool unit connected to the mobile hydraulic tool.
  • the tool unit is either a drawing or a printing tool unit.
  • a typical embodiment of a drawing tool unit is, for example, a blind rivet setting unit, in which blind rivets are set on the basis of the pulling movement applied by the drive piston and acting on the blind rivet.
  • a print tool unit may be formed by a stamping unit which is used to form openings in a component.
  • the invention has for its object to provide a mobile hydraulic tool, in which the movement provided by the drive piston can be used to selectively drive a drawing tool unit and a printing tool unit.
  • Characteristic of the mobile hydraulic tool according to the invention is that the hydraulic tool housing is formed, on the one hand, for arranging the drawing tool unit which can be connected to the drive piston and, on the other hand, for arranging the pressure tool unit which can be connected to the drive piston.
  • the possibility of both sides of the hydraulic tool housing - viewed in the longitudinal axis direction of the drive piston, along which the drive piston within the hydraulic tool housing is adjustable - to arrange a tool unit and connect to the drive piston allows the adjustment of the drive piston between its initial position and its end position both to drive a pressure acting as well as to drive a tensile tool unit to use.
  • the pressure tool unit can be arranged on the side of the hydraulic tool housing into which the drive piston moves starting from the starting position into the end position.
  • the drawing tool can be arranged on the side of the hydraulic tool housing into which the drive piston moves from the end position to the starting position.
  • the inventive design of the mobile hydraulic tool thus makes it possible, by exchangeable, adapted to the hydraulic tool housing drawing tool and print tool units to use the mobile hydraulic tool both for performing drawing work as well as printing work.
  • the corresponding tool unit can be arranged on the corresponding side of the hydraulic tool housing in a simple manner and connectable to the drive piston.
  • at least two mobile hydraulic tools for performing drawing and printing can be dispensed with by the simple interchangeability of the tool units.
  • connection of the tool units with the hydraulic tool housing can basically be done in any way. It is conceivable, for example, simple latching connections or latches in the manner of a bayonet lock. According to a particularly advantageous embodiment of the invention, however, it is provided that the hydraulic tool housing on both sides of a thread, in particular an internal thread, which is formed on the one hand to the arrangement of the drawing tool unit and on the other hand to the arrangement of the printing tool unit.
  • the inventive design of the hydraulic tool housing with two, preferably at the opposite ends - viewed in the adjustment of the drive piston - arranged threads, in particular internal threads, allows a particularly simple and secure positioning of connectable to the hydraulic tool housing tool units.
  • the tool units which are connected to both the hydraulic tool housing and the drive piston for transmitting its adjustment, are secured in position in a special way due to the connection made via the thread, so that occurring compressive and tensile forces can be reliably transferred to the tool units.
  • the threaded connection protects the interior of the hydraulic tool housing, in particular the cylinder section, which serves to guide the drive piston, against soiling, which could lead to a malfunction of the mobile hydraulic tool.
  • connection of the print tool unit and the drawing tool unit takes place, as already explained above, in such a way that the movement of the drive piston is transmitted to the drawing or pressing tool of the drawing tool unit or printing tool unit.
  • the drawing tool may be, for example, a jaw set in a printing tool about a punching head.
  • the design of the drive piston, so that it can be connected to both the drawing tool and with the pressure tool, takes place in any way.
  • the drive piston in the region of its end, the facing the arrangement of the drawing die unit formed side of the hydraulic tool housing, for connection to a pulling tool and in the region of its end, which faces the arranged for the arrangement of the printing tool unit side of the hydraulic tool housing, is designed for connection to a pressure tool.
  • the mutually opposite ends of the drive piston for the arrangement of the printing tool or drawing tool of the printing tool unit or drawing tool unit are formed.
  • a corresponding configuration of the drive piston makes it possible to reliably connect the respective tool unit and the associated tool (drawing tool or pressure tool) to the hydraulic tool housing and the drive piston independently of the design of the opposite end of the drive piston. It is also possible to design the opposite ends of the drive piston according to the tools to be used differently, so that a good adaptability of the hydraulic tool can be done to the tool units to be used.
  • the drive piston may, for example, be provided with internal threads, which allow a reliable connection of the drive piston with the tool.
  • the drive piston is longitudinally channeled, in particular has a passage opening.
  • a longitudinally channeled, preferably a through-opening having drive piston makes it possible to connect the drawing tool unit and / or printing tool unit or the drawing tools or printing tools with a tool opposite end of the drive piston non-positively and / or positively.
  • the passage opening can be used to use a mandrel, which abuts against the drawing tool opposite side of the drive piston on this and thereby convert an adjusting movement, in which the drive piston presses on the mandrel, in a pulling movement of the drawing tool.
  • the drive piston at its end position facing the end position particularly advantageously has a stop surface surrounding the passage opening, which enables a good and planar contact of a coupling means, for example of the mandrel but also a pressure tool, so that a reliable power transmission is ensured.
  • the hydraulic tool housing is connected to a connectable with a hydraulic line connection piece, so that pressurization causes an adjustment of the drive piston from the starting position to the end position in the cylinder portion of the hydraulic tool housing.
  • the connecting piece for the hydraulic line is rotatably and / or pivotally connected to the hydraulic tool housing.
  • FIGS. 1 and 2 is a designed as a riveting tool mobile hydraulic tool 1 in an exploded view ( Fig. 1 ) and in a sectional view ( Fig. 2 ).
  • the mobile hydraulic tool 1 has a drive unit 2 which has a hydraulic tool housing 4 and a drive piston 3 adjustably mounted in the hydraulic tool housing 4 between a starting position and an end position.
  • the adjustment of the drive piston 3 takes place hydraulically, the drive piston 3 is mounted liquid-tight in the cylinder housing 5 of the hydraulic tool housing 4 within the hydraulic tool housing 4 on a cylinder inner surface 28, so that pressurization of the drive piston 3 via a connectable to a connecting piece 43, not here shown hydraulic line, a displacement of the drive piston 3 from the in Fig. 1 shown starting position in an end position, not shown here causes.
  • a ring seal 30 for sealing against the drive piston 3 and arranged on the drive piston 3 a voltage applied to the cylinder inner surface 28 ring seal 47.
  • this is designed as a riveting tool, wherein the hydraulic tool housing 4 and the drive piston 3 are connected to a drawing tool unit 52.
  • the drawing tool unit 52 has u. a. a pulling tool 10 and a mandrel 11, which are coupled to the drive piston 3 and a sleeve receptacle 13 and a guide sleeve 7, which are connected to the hydraulic tool housing 4, on.
  • the drive piston 3 is used to adjust the mandrel 11, which is releasably connected via a coupling unit 12 releasably connected to the pulling tool 10 in the longitudinal axis direction and in the circumferential direction.
  • the mandrel 11 extends within a through hole 44 of the drive piston 3 wherein the insertion depth of the mandrel 11 is limited in the drive piston 3 by a drive piston 3 facing flange which rests in the mounted position in the longitudinal axis direction of a stop surface of the drive piston 3.
  • Two coupling half shells 14 used to form the coupling unit 12 have in the assembled state inwardly projecting grooves 15 and webs 50, which engage in the grooves 41 between the projections 41 of the mandrel 11 and the pulling tool 10 and thus produce a positive connection in the longitudinal axis direction.
  • the position of the coupling half shells 14 is also secured via arranged on a coupling half shell 14, not shown pins, which engage in pin receivers 16 of the other coupling half-shell 14.
  • the drawing tool 10 To guide the drawing tool 10 between the rivet receiving position and the setting position of the mandrel 11 associated position the drawing tool 10 is provided with a guide unit 6 forming a guide sleeve 7, which is internally adapted to the diameter of the coupling unit 12 and thus serves as a linear guide.
  • the guide sleeve 7 is attached via an external thread 32 to an internal thread 33 of a sleeve receptacle 13, which is fixed via an external thread 34 on an arranged on the hydraulic tool housing 4 internal thread 35.
  • a circlip 51 which is arranged coaxially to the guide sleeve 7 and rests against an end face of the sleeve receptacle 13.
  • the guide sleeve 7 For receiving a rivet head 8 adapted to the drawing tool 10, the guide sleeve 7 has a rivet head receptacle 9 within which a plurality of holding magnets 29 are arranged in an annular manner coaxial with a passage opening, which permit releasable attachment of the rivet head 8 to the guide sleeve 7.
  • the mandrel 11 releasably connected to the pulling tool 10 forms with a guide pin 22, a threaded sleeve 23, a rotary wheel 24 and a helical compression spring 21 a unit which is inseparably connected during normal operation.
  • the mandrel 11 has a bore 26, within which the guide pin 22 is axially displaceable.
  • the axial displaceability is determined over the length of a longitudinal axis direction by the guide pin 22 extending slot 25, which extends through this slot 25 connected to the mandrel 11 securing bolt 20.
  • the securing bolt 20 also ensures a transmission of the rotational movements of the locking pin 22 on the mandrel 11, wherein this rotational movement is then transmitted to the drawing tool 10.
  • the rotational movement of the guide pin 22 is caused by the operation of a rotary wheel 24, which is arranged rotationally fixed in a receiving opening 46 of a receiving portion 48 of the guide pin 22.
  • the threaded sleeve 23 has an internal thread 42 which is screwed onto an external thread 39 of an adapter sleeve 17, wherein the Adapter bush 17 with a further male threaded portion 38 in an internal thread 37 of the hydraulic tool housing 4 can be screwed.
  • different tool units can be combined with the unitary hydraulic tool housing 4 of the mobile hydraulic tool 1 via the adapter bush 17.
  • the helical compression spring 21 is supported at one end to an inner surface of the threaded sleeve 23 and the other end to a flange of the mandrel 11. In the assembled state, the helical compression spring 21 thus biases the mandrel 11 in the direction of the drive piston 3. A displacement of the drive piston 3 and of the drive piston 3 positively connected in the longitudinal axis direction mandrel 11 from the starting position to the end position thus takes place against the spring force of the helical compression spring 21st
  • the internal threads 35, 37 arranged on both sides, at the opposite ends of the hydraulic tool housing 4, permit a simple conversion of the mobile hydraulic tool 1 with a drawing tool unit 52 or a printing-tool unit not shown here.
