Definitions

  • the invention relates to a device for coring castings, as characterized in the preamble of claim 1.
  • Such devices are known (DE-Al-29 47 795 and US-A-1 768 428), it being disadvantageous that the impact hammer acts directly on the casting to be cored.
  • the known devices can therefore only be used to a limited extent and are usually limited to simple castings with a few aluminum cores.
  • the facility should enable automatic operation without subsequent manual work.
  • One embodiment of the invention consists in that the cast part can be inserted into the stenter frame on a transport pallet and, when tensioned in the stenter frame, is exposed to the impact.
  • FIG. 1 Further particularly advantageous embodiments of the invention are the arrangement of a rotating device in which the emptying of the cavities of the casting takes place from the core sand previously loosened by the impact, and the arrangement of roller tables with a lifting table at each end, through which an automatic workflow and a Return of the empty transport pallets is achieved with little.
  • the advantageous arrangement of the deflection device and the rotating device in a sound-absorbing cabin also ensures a low-dust environment in addition to soundproofing.
  • the entire device has a deflection device 1, a rotating device 2 and a transport device 3.
  • the deflection device 1 and the rotating device 2 are arranged in a sound-absorbing cabin 4, through which two roller conveyors 5 and 6 lead for transport pallets 9, which are operatively connected to each other at both ends of the cabin 4 by means of two lifting tables 7 and 8.
  • the deflection device 1 has a frame 10 standing on vibration dampers 11, on which a clamping frame 12 is arranged so as to be vertically displaceable. At least one, preferably pneumatically operated, hammer 13 fastened in the frame 10 engages on a cross member 14 of the clamping frame 12 from below.
  • a cross member 14 of the clamping frame 12 On the frame 10, swiveling or lifting and lowering transport rollers 15 are arranged, which form a roller plane with rollers 5a in their upper position and are thus part of the roller conveyor 5. By pivoting the transport rollers 15, the transport pallets 9 loaded with the casting 50 to be cored can be lowered onto the clamping frame 12.
  • a clamping means 16 preferably a hydraulic cylinder, arranged on the clamping frame 12 on the side opposite the hammer 13, presses a clamping element 16a against the casting 50 after its actuation, as a result of which the latter is firmly clamped in the clamping frame 12 together with the transport pallet 9 resting on the cross member 14 becomes.
  • the blows generated by the hammer 13 in rapid succession reach the casting 50 indirectly via the clamping frame 12 and the transport pallet 9, whereby the cores or the solid core sand in the casting 50 are loosened.
  • FIG. 1 and 3 has a frame 20 on which circumferentially distributed rollers 21 are arranged, between which a frame 22 is rotatably mounted about a horizontal axis 23.
  • This frame 22 is provided with transport rollers 25 which are part of the roller table 5 in a horizontal position defined by a locking device 24. In this position, the transport rollers 25 are operatively connected to a drive 31.
  • a clamping device 26 is fastened to the frame 22 and has a clamping arm 26a which can be pressed against the cast part 50 by spring force. When moving the transport pallet 9 in and out with the Casting 50, the tensioning arm 26a can be lifted off the casting 50 against the spring force by means of an actuating device 27 fastened to the frame 20.
  • the spring force is preferably generated by a torsion spring 28.
  • the actuating device 27 is advantageously a pneumatically or hydraulically actuated cylinder, the piston rod 29 of which can be pressed against a lever 30 of the tensioning arm 26a and is brought into a fully retracted position during the rotation of the frame 22.
  • a motor-driven roller 21 or another drive device By means of a motor-driven roller 21 or another drive device, the cast part 50 clamped in the frame 22 is rotated until the cavities of the cast part are free of the already loosened core sand.
  • the first lifting table 7 simultaneously forms the loading station 17 for the transport pallets 9.
  • the here from z. B. the unpacking station supplied castings 50 are placed on the transport pallets 9 by means of a device, not shown, where they are held in a fixed position by means of parts 19 engaging in the castings 50.
  • the castings 50 are cylinder blocks of engines, the parts designed as pins 19 coming to rest in the cylinder bores.
  • the pins 19 can be inserted into the transport pallets 9 at different predetermined distances depending on the dimensions of the cylinder blocks to be cored.
  • the loaded transport pallets 9 are brought by means of the lower roller table 5 through a closable cabin opening into the deflection station 1, in which the cores are broken or loosened by means of the blows of the impact hammer 13 acting indirectly on the cast part, as already described.
  • the transport pallet 9 with the cast part 50 is rolled into the rotating device 2, where, as already described, the cavities of the cast part are emptied by its rotation.
  • the now completely cored casting 50 is now transported on the transport pallet 9 by means of the rollers 5a to an unloading station 18 which is designed as a lifting table 8.
  • the casting 50 is lifted from the transport pallet 9 by means of devices (not shown) and fed to a further transport device.
  • the empty transport pallet is raised by means of the lifting table 8 up to the height of the upper roller table 6 and transported through the cabin 4 to the first lifting table 7.
  • the transport pallet rolled onto the lifting table 7 is then lowered to the height of the lower roller table 5 and can be loaded there with a further cast part.
  • the entire cycle is carried out in cycles and automatically, a transport pallet 9 with cast part 50 being located in the deflection device 1 and in the rotating device 2 at the same time and at least four further transport pallets 9 in circulation according to FIG. 1.
