Definitions

  • the invention relates to a device for the removal of the chips and coolant accumulating on a machine tool, the term “coolant” also being used to include admixtures of other liquids, for example oil, if appropriate.
  • the object of the present invention is therefore, in particular, to provide a flat-construction device of the type mentioned, to which the substances concerned here in the machine bed fall solely due to the gravity of these substances and which, given this spatial limitation, provide sufficient storage space, so that at Interrupting the removal, the amount of the resulting substances can be safely absorbed at least until the machine tool has completed a full work cycle and can be switched off.
  • a channel-like receptacle which can be inserted into the lower region of a machine tool below the swarf and coolant outlet of this machine, that the receptacle is formed from an inner groove and an outer groove, wherein the outer groove surrounds the inner groove at a distance, that in the side walls of the inner groove for coolant overflow openings to the outer groove are provided, that the grooves are closed at one end and open at the other, the open end of the inner groove at the entry level of a chip shredder or above and the open end of the outer channel below the entry level of the chip shredder enters a transport system for the joint further transport of optionally shredded chips and coolant.
  • the cooling liquid which may still contain small chips, passes into the outer groove, while the chips and cooling liquid remaining in the inner groove into the chip shredder.
  • the coolant that is in the outer groove is then gets below the chip shredder into the transport system of the device, so does not pass the chip shredder.
  • the device according to the invention can be driven in such a way that coolant only reaches the outer channel via the overflow openings if complete removal, for example due to congestion, would otherwise no longer be guaranteed.
  • the chips that are still washed away when passing through the overflow openings are small, since larger chips settle as sediment in the inner channel and are also retained by the overflow openings.
  • the chips carried in the outer channel do not have to be fed to the shredder for further transport.
  • At least the inner channel has a bottom which is inclined in the transport direction, so that the material contained therein can be transported without additional use and without additional measures.
  • means for mechanical support for the transport of the chips are provided at least in the inner groove. Furthermore, at least the inner channel can be provided with a rinsing connection to support the transport of the chips.
  • the invention further provides that the inner and the outer channel can be connected to one another in a sealing manner in the region of their upper edges, with the exception of the overflow openings. As a result, the undesirable leakage of coolant can be avoided.
  • the inner and / or the outer groove, in the installed state lies sealingly against the edge of the chip and coolant outlet from the machine tool. This also serves to reliably take over the substances emerging from the machine by the device according to the invention.
  • a proposal of the invention provides that inlet openings are provided on the upper edge of the outer channel for absorbing leaks in the area of the machine bed.
  • the overflow openings in the walls of the inner channel are arranged one behind the other in a height-graded manner in the transport direction. In this way it is easy to determine the degree of utilization of the channels at the moment. In this way, the number of free overflow openings and thus the amount of overflowing liquid can also be recognized accordingly.
  • the device according to the invention provides that the transport system has a scratch pushing the chips forward and feeding them to a pump, and the chips and the coolant are carried on by pumps for further disposal.
  • FIG. 1 shows a perspective view of an embodiment of the device according to the invention with a schematically indicated machine tool
  • Figure 2 is a side view of the device of Figure 1 and
  • Figure 3 is a detailed view of an inventive design of outer and inner gutter.
  • a machine tool 1 is indicated schematically, the machine bed of which has an opening 2.
  • the machine tool 1 is a cutting machine of any design and purpose.
  • a u-shaped inner channel 3 protrudes into the opening 2, which in turn is placed in a likewise u-shaped outer channel 4.
  • the side walls 5 and the bottom 6 of the inner gutter on the one hand and the side walls 7 and the bottom 8 of the outer gutter on the other hand are arranged at a distance from one another, so that the overall cross section of the outer gutter 4 is substantially larger than the cross section of the inner gutter 3. This means that the entire channel cross-section, when the inner channel and the outer channel 4 are made effective, essentially corresponds to the total cross-section of the outer channel 4.
  • the upper edge 9 of the inner groove 3 is bent obliquely outwards and is connected there to the upper edge 10 of the outer groove 4.
  • the fold there are passages 11 for the removal of possible leaks from the machine bed.
  • the fold is provided with a seal 12, which creates a sealing cooperation between the inner channel 3 on the one hand and a trailing edge 13 of the machine bed.
  • the inner groove 3 and the outer groove 4 are closed at their rear ends.
  • overflow openings 14 are provided, through which coolants from the inner channel 3 into the outer channel 4 can overflow when the coolant level has reached a corresponding level.
  • the overflow openings 14 are arranged one behind the other in the transport direction and their height is offset from one another. This means that the number of overflow openings addressed increases with increasing level. This results in a level indicator, which indicates, for example, the beginning or existing blockages in the inner channel 3.
  • Corresponding monitoring devices can be assigned to individual or to all overflow openings.
  • the overflow openings are placed and dimensioned such that they essentially only allow the coolant to pass out of the swarf-coolant mixture - if necessary using sieves in the overflow openings. By monitoring the overflow openings, it can be determined whether or which of these openings are being flowed through. Thereupon in turn, if desired, control intervention can be made in the method of the device or even the machine tool.
  • the bottom 6 of the inner channel 3 is inclined in the transport direction and ends at its end lying on the right in FIG. 2 at the entry level of a chip shredder 15 or slightly above it.
  • the bottom 8 ends below the entry level of the chip shredder 15, so that coolant guided in the outer channel 4 opens into a transport system 16, in which the cooling liquid is again combined with the chips guided through the chip shredder 15 and possibly further shredded there.
  • the mixture formed in this way is fed from a scratch 17 to the inlet 18 of a pump and from there is conveyed on for further treatment.
  • the mixture of chips and coolant can flow off in the inner channel solely due to the incline of this channel. Aiding the drainage can be promoted by introducing additional rinsing liquid or by mechanical means. The same applies to the outer channel 4.

Abstract

L'usinage de pièces dans des machines-outils produit de grandes quantités de copeaux et de liquide de coupe. Lors de l'évacuation de ces substances, en raison des grandes quantités produites, un arrêt d'urgence de la machine-outil peut être nécessaire en cas de blocage de la voie de transport, ce qui peut endommager la pièce et l'outil. Selon l'invention, ce problème est résolu grâce à un réceptacle insérable, de type canal, disposé dans la zone inférieure de la machine-outil (1) sous la sortie des copeaux et du liquide de coupe, ce réceptacle étant formé d'un conduit intérieur (3) et d'un conduit extérieur (4) entourant le conduit intérieur, à une certaine distance de celui-ci, ledit conduit intérieur (3) comportant, dans ses parois latérales (5), des ouvertures de trop-plein donnant sur le conduit extérieur. En cas de blocage du conduit intérieur (3) par des copeaux, on peut ainsi continuer à évacuer au moins le liquide. Si une autre partie du transport est bloquée, au moins une grande quantité de liquide peut être stockée provisoirement de sorte que l'on puisse dans tous les cas arrêter la machine-outil de façon contrôlée et éviter ainsi un endommagement de la pièce et de l'outil.
