Definitions

  • the invention relates to a device for removing feeders and sprues from a casting, a wedge being connected to a displaceable piston and the side faces of the wedge being covered by bodies which can be moved relative to one another.
  • Devices of this type are used, in particular, in school stores where an energy-saving separation of feeders and risers from the casting is desired. This separation is a common operation in the course of casting production.
  • the object of the present invention is to provide a portable device which is simple to manufacture, works effectively and is reliable even in rough operation.
  • the bodies are connected via bolts guided in longitudinal openings to a linear motor to which the piston is assigned, and are held in contact with the side surfaces of the wedge by means of pressure and / or pulling means.
  • the inventive measures create a very simple device, the individual parts of which can be easily detached and replaced, but which nevertheless provides a high level of operational reliability.
  • By guiding bolts in longitudinal openings it is ensured that the body covering the side surfaces of the wedge moves in a simple movement when the wedge is moved outwards and thus the entire force is used to break off the feeders and sprues. If the bodies are formed in a U-shape, this results in easy manufacture and nevertheless high bending rigidity, which in turn benefits operational reliability.
  • the use of springs the length of which can be adjustable under certain circumstances, also makes it possible to easily adjust the contact force of the body on the side surfaces of the wedge.
  • FIG. 1 shows the device according to the invention in the idle state
  • FIG. 2 shows the Device according to the invention in use
  • Figure 3 is a section AA of Figure 2.
  • the device according to the invention consists of a linear motor 1, in which a piston 7 is arranged displaceably.
  • the piston 7 carries a plunger 8 which is movably connected to a wedge 4.
  • the wedge 4 can thus be brought into an operating position according to FIG.
  • the side surfaces of the wedge 4 are at least partially covered by bodies 2.
  • these bodies 2 are U-shaped and thus encompass the wedge 4.
  • the bodies 2 are articulated via bolts 6 to a flange 9 of the linear motor.
  • this flange 10 has longitudinal openings 5 in which the bolts 6 can slide.
  • the bolts can be provided with rollers at their upper end, or a sliding block can be used.
  • the axes of the longitudinal openings are at an angle ⁇ , which corresponds to half the apex angle of the wedge 4, or at a larger angle to the normal plane N of the longitudinal axis of the device.
  • 2 retaining bolts are provided on the bodies, on which the ends of a spring 3 engage. This spring has the effect that the bodies 2 always rest on the side surfaces of the wedge 4 and that when the piston 7 moves back into its starting position, the bodies 2 also return to their starting position.
  • only a single spring is shown, but it is also possible to arrange a plurality of springs.
  • the springs 3 can be replaced by other suitable means, such as hydraulics or pneumatic cylinders and the like.
  • the special arrangement of the longitudinal openings 5 achieves a neutralization of the bending forces on the bodies 2 and the springs 3 ensure that the bodies 2 are always in contact with the side surfaces of the wedge 4, but nevertheless an immediate reaction to a movement of the wedge by a movement of the Body 2 is given to the outside. Because the bodies 2 are U-shaped, they can be easily manufactured and at the same time the bending rigidity of the working bodies 2 is increased.
  • the device according to the invention can be produced very easily since only simple bodies and surfaces are used.
  • the connection of the individual parts is simple and can be easily solved, so that an exchange of the individual parts is possible quickly. Nevertheless, a high level of operational safety is guaranteed, which is a great advantage especially in the rough operation that prevails in foundries.
  • By simply connecting the individual parts it is also possible to clean them quickly and easily and thus remove any dust and particles that may have penetrated between the individual parts.
