Definitions

  • the present invention relates to a ring press, comprising a mandrel, via which an annular workpiece to be pressed can be fed in the axial direction of the ring press and on which the workpiece is supported, a plurality of radially movable movable pressing elements, with which pressure on the workpiece is exercisable, and a in the circumferential direction relative to the pressing elements rotatable pressure generating arrangement, the rotation of which relative to the pressing elements, the pressing elements are moved from a release position to a pressing position, wherein the pressure generating arrangement comprises a plurality of rollers which is formed to generate pressure via a respective radial outer edges of the pressing elements unwinding continuous circumferential path and wherein the pressure generating arrangement comprises a race on the radial inside of which roll off the rollers.
  • Such a ring press is from the DE 10 2007 031 482 A1 known.
  • the pressure generating arrangement shown there is driven via a gear transmission, in particular a pinion, which meshes with a drive ring, wherein the pinion is connected by means of a shaft with an electric motor.
  • the sleeve can be centered at the beginning of the application of pressure by means of the pressing elements relative to the mandrel.
  • the sleeve may initially be held with its inner circumference at a small distance from the outer circumference of the mandrel, since it is held or clamped on its outer circumference by the pressing elements.
  • pressure increase is a plastic deformation of the sleeve, wherein the sleeve material is displaced towards the mandrel by radially moving the pressing elements towards the mandrel and then possibly rests against this.
  • the plastic deformation generated in particular can lead to a reduction of the inner and outer diameter of the sleeve, wherein the thickness of the sleeve remains substantially the same as before pressing in the ring press or only slightly reduced.
  • Such a pressing operation enables the production of sleeves with high dimensional accuracy and precision.
  • the object of the invention is to develop a ring press of the known type such that the above disadvantages can be avoided.
  • the ring press comprises a drive which is designed such that it can be coupled or coupled to the raceway without transmission, in order to normally transmit the speed generated by the drive or the torque generated unchanged to the raceway.
  • Such transmission-free power transmission of the drive power to the race avoids losses in a translating gear such that the movement of the race is substantially identical to the movement of the drive.
  • a certain speed per minute or a certain partial rotation in one or the other direction can be precisely controlled and transmitted to the pressure generating device, in particular the race.
  • Transmission-free in this context is to be understood that no rotational movements transmitting gears or the like. Are present, which translate to a reduction of the drive generated rotational movement. Transmission-free should not exclude, however, that between the drive and the thus coupled raceway further, be offset by the drive in a similar manner rotatable components, which in particular produce the coupling between the race and the drive.
  • the drive is an electrically driven torque motor with a radially inner, forming a hollow shaft rotor and an outer stator.
  • the race can be coupled or coupled to the rotor.
  • Torque motors are high torque optimized large servo motors where the rotor is normally designed as a hollow shaft.
  • the torque motor can be used as a gearless direct drive of the race, which can be generated by the torque motor high torques at relatively low speeds.
  • These properties are very important for a ring press according to the present invention, since relatively large sleeves are made with a diameter of up to 15 cm, wherein the material to be processed has a thickness of several millimeters.
  • the use of a torque motor as a drive for the ring press allows a compact design, since the drive is installed concentrically around the pressure generating arrangement.
  • the raceway is preferably on its radial outer side in the axial direction designed conical and is located on the inside of an axially opposite conical clamping ring of the pressure generating arrangement on.
  • the clamping ring is preferably connected to a rotor connected to the drive ring of the pressure generating arrangement or to the rotor, in particular screwed.
  • the clamping ring in the axial direction relative to the race and the drive ring or rotor is adjustable to adjust the pressure acting on the race and thus on the workpiece pressure.
  • the clamping ring can also be referred to as a collar.
  • the clamping ring is frictionally received between the drive ring or rotor and the raceway.
  • the rotational movement of the rotor on the raceway transmitting components of the pressure generating arrangement are received substantially free of play and there is no slippage between the individual ring components and the rotor during normal operation of the ring press.
  • the frictional connection of the clamping ring is detachable, preferably by establishing hydraulic pressure between the friction surfaces of the clamping ring, the race and the drive ring or rotor.
  • the circumferential path of the ring press on a regular profile in the circumferential direction with alternating radial elevations and reductions, such that when rolling the rollers over a survey all the pressing elements are moved synchronously in the pressing position.
  • the pressing elements In order to enable the radial advancing movement of the pressing elements, it is proposed that slot-like openings are formed in the pressing elements, in which stationary guide elements are received with respect to the pressing elements, which guide the radial movement of the pressing elements to the center of the dome or the ring press.
  • the pressure generating arrangement, the pressing elements and the guide elements are preferably supported immovably in the axial direction. They are in particular on a base plate or cover.
  • the pressing elements are preferably movable by return means from the pressing position to the release position, when the rollers are in the subsidence of the profile of the continuous circumferential path, wherein preferably the return means act hydraulically and / or mechanically or are formed. Such return means allow accelerated change from the press position to the release position.
  • the invention also relates to a working machine, in particular wire or strip bending machine, for machining, in particular forming, continuous workpieces with a wall-like basic body which has a front and a rear machining side, with at least one tool unit for machining the workpieces and with a ring press having at least some of the above features.
  • a working machine in particular wire or strip bending machine, for machining, in particular forming, continuous workpieces with a wall-like basic body which has a front and a rear machining side, with at least one tool unit for machining the workpieces and with a ring press having at least some of the above features.
  • Such machines are used in particular in the production of sleeves made of metal, wherein initially plate-like workpieces are supplied to the tool unit, which have preferably been previously separated from a strip of material.
  • the tool unit preferably has a plurality of bending punches, in particular four bending punches, which are designed such that they can transform the bending-type plate-like workpiece into a cylindrical sleeve.
  • the sleeve thus formed is transported in the axial direction from the tool unit to the ring press.
  • the ring press axially adjoins the tool assembly in the direction of the bending axis, such that the deformed sleeve can be moved by the bending core of the tool assembly via the mandrel of the ring press.
  • the sleeve Prior to pressing by means of the pressing members, the sleeve may abut with an axial portion of its inner periphery at the uppermost axial outer peripheral portion of the mandrel.
  • the pressing elements are moved toward the sleeve in the radial direction, the latter is lifted off the mandrel and held centered (concentrically) therewith, in particular forming an annular gap between sleeve and mandrel.
  • the sleeve material Upon further pressure build-up, the sleeve material is plastically deformed and displaced by the pressing elements in the direction of the mandrel. In this case, the sleeve experiences in particular a reduction in its inner and outer diameters at approximately constant sleeve thickness.
  • the tool unit and the ring press are mounted on the same side of the main body, wherein the ring press covers the tool unit at least partially in the operative state of the machine.
  • the tool unit and the ring press are mounted on different sides of the body and that the deformed by the tool unit sleeve can be moved through an opening formed in the body through the ring press.
  • the ring press is pivotally mounted on the base body, preferably a orthogonal to the ground vertical axis, such that by pivoting the ring press access to the tool unit is possible.
  • the ring press can pivot in such an embodiment door-like away from the tool unit, so that, for example, maintenance work on the bending tools or bending dies can be performed.
  • the ring press is locked in the operable state relative to the base body, so that its mandrel is aligned in the axial direction with the bending core of the tool unit.
