Definitions
- the invention is based on a hydraulic pressure intensifier according to the genus of the main claim.
- a hydraulic pressure intensifier of the generic type (DE-OS 42 23 411) the piston spindle is used to generate the high pressure of the plunger via a pneumatic drive piston actuated.
- this pressure intensifier which in some Cases do not exist, or always with certain circumstances is connected and the use of the device by such Makes air supply dependent.
- DE-OS-40 26 959 discloses an electric motor, via ball screw and corresponding nut driven linear unit with hydraulic Intensifier. However, this design is quite complex.
- the hydraulic pressure intensifier according to the invention with the has characteristic features of the main claim in contrast, the advantage of simplifying the construction.
- Lifting forces generated by electrical energy are sufficient for the to generate hydraulic high pressure.
- the electrical energy in the generated electrical power is controlled, for example, by generating a lower force for the rapid traverse and when the plunger is immersed in the work area and due to the resulting higher pressure or mechanical process, an electrical switchover takes place. Also this is an additional advantage of the inventive solution.
- Electric motor designed as a linear motor, in which the armature at least indirectly with or with the plunger connected drive spindle and / or the piston rod of the Working piston is connected, so that especially the rapid traverse through the linear forces can take place and where the drive spindle as Armature of the linear motor can serve.
- Such linear motor on the piston rod can after immersion of the plunger in the working area on the linear motor Holding forces, due to the high pressure ratio, light be overcome, especially with rapid traverse and return stroke a quick adjustment is possible.
- the rapid traverse before the working stroke and / or after the Return stroke lying at least partially hydraulic causes is provided.
- the Invention is inside the housing and around the piston rod as well as an annular space bounded by the working piston hydraulic control available.
- This enabled hydraulic servo function allows the use of known means, such as servo motor and the like.
- the Invention is in the hydraulic connection between Storage space and annulus, or compensation space each one Control valve arranged, which towards the storage space (5) or annular space (16) guaranteed free flow, however in reverse Direction throttles the flow.
- a housing 1 of a hydraulic pressure booster is over a working piston 2 a piston rod 3 driven and a hydraulic work space 4 is provided.
- a Storage space 5 is provided, which with the work space 4 by a Control bore 6 is connected and by a storage piston 7 is limited.
- a Plunger 8 Coaxial with the accumulator piston 7 is a Plunger 8 provided with a drive spindle 9 connected after a certain stroke in the control hole 6 dips, this locks and the continuation of the Hubes in the workspace 4 one according to the Diameter ratio of plunger 8 and working piston 2 given high pressure.
- a power stroke via the plunger 8 is generated for machining the workpiece, for example one Punching the same.
- Fig. 1 is with the Accumulator piston 7 in an axial line with the plunger 8 a Drive spindle 9 attached, which penetrates a linear motor 11, which is arranged outside of the housing 1 and attached to this is.
- a linear motor 11 which is arranged outside of the housing 1 and attached to this is.
- Coaxial to Drive spindle 9 is an annular piston 12 axially displaceable on this arranged, which is loaded by a spring 13 and on that delimits a compensation space 14 facing away from the spring 13, which on the other hand is limited by the accumulator piston 7.
- This compensation space 14 is connected via a line 15 to both Storage space 5 and connected to an annular space 16, the formed between working piston 2, housing 1 and piston rod 3 is.
- control valves 17 are arranged, each a free flow to the storage space 5 or the annular space 16 ensure, however, the flow in the opposite direction throttle, this throttling is adjustable.
- Throttling effect during rapid traverse or working stroke of the pressure intensifier on.
- FIG. 2 The embodiment is also the piston rod 3 only shown in principle operable spindle drive, the particular is designed as a linear motor.
- Servo motor 19 and an additional reservoir 21 for hydraulic fluid removable.
