Definitions

  • the invention relates to a device for deburring foundry cores, having a vibrating device, a fixed substructure carrying the vibrating device and a deburring template according to the preamble of patent claim 1.
  • an apparatus and a method for deburring foundry cores is also known from FR-A-1 590 395, a quasi three-dimensionally vibrating vibrator causing vibratory movements serving for deburring.
  • the burr is also hammered off here due to the three-dimensional vibrating vibrator.
  • a stand or tripod vibrates using the vibrator and two flexible metal plates spent.
  • the teaching of the invention is based on the object of designing and developing the known device for deburring foundry cores in such a way that effective deburring without impulses caused by hammering with reduced tool wear is achieved with simple technical means.
  • the device according to the invention in which the above-mentioned object is achieved, is characterized in that the vibration movement of the vibration device takes place exclusively in the tangential direction to the foundry core and that there is no play between the contours of the core to be deburred and the contours of the deburring template, so that the burr is cut off when the core is passed through the deburring template.
  • the vibration device is designed in accordance with the invention in such a way that the vibration movement of the vibration device takes place exclusively in the tangential direction to the foundry core.
  • the edge of the deburring template therefore acts like a cutting tool that cuts the burr off the core in the course of the vibration movement.
  • the oscillation width of the vibration device is preferably infinitely variable.
  • the deburring template can be adjusted in two axial directions by means of adjusting screws. This prevents namely that not only the ridge but also the outer area of the core is cut or scraped off.
  • the vibration device has a vibration part with a magnetic oscillator. Furthermore, an oscillating plate with buffers is provided, the buffers serving to dampen the oscillating movement. So that a lateral deflection of the oscillating plate is effectively prevented, the vibrating device or the oscillating plate is provided with a leaf spring which only allows the oscillating movement in the vertical direction.
  • deburring templates can be provided for simultaneous deburring of several cores, which significantly increases the throughput, particularly in the case of automatic operation.
  • This handling device is used for the automatic execution of the work steps from the removal of ejected cores from a core box through the insertion of the cores into the deburring template up to the further transport of the cores for further handling.
  • automatic manipulations are possible, the elasticity of the grippers preventing damage to the foundry cores or the like.
  • a guide which acts between the handling device and the substructure carrying the vibrating device.
  • the device for deburring foundry cores 3 shown in FIGS. 1 and 2 has a handling device 1 with elastic grippers 2 for receiving the foundry cores 3.
  • the foundry cores 3 are automatically removed from a core box (not shown in the figures) by means of the handling device 1 and guided over the deburring device having a deburring template 4.
  • a vibrating part with a magnetic oscillator 8, an oscillating plate 5, with buffers 6 and with leaf springs 7 is provided on a fixed substructure 10.
  • the deburring template 4 is also assigned to the substructure 10.
  • the handling device 1 is guided without play in the fixed part or in the substructure 10, so that the burr on the deburring template is virtually cut off.
  • a guide 9 acts between the base 10 and the handling device 1.
