Definitions

  • the invention relates to a device and a method for cooling shrink chucks according to the preambles of claims 1 and 26 or a device for receiving shrink chucks according to the preamble of claim 23.
  • the insert tool can be drills, milling cutters or the like.
  • shrinkage chucks are thermally heated by inductive shrinking equipment, whereby the inner diameter of the shrink chuck increases.
  • an insert tool to be clamped is inserted into the shrink chuck.
  • the ratio of the inner diameter of the shrink chuck to the shank diameter of the insert tool (the drill, the milling cutter, etc.) is designed such that during subsequent cooling of the shrink chuck, the insert tool is firmly clamped with the shrink chuck.
  • shrink chucks have proven themselves in practice.
  • the inductively heated shrink chuck must be cooled to tension the tool.
  • Cooling devices which reduce the cooling time, are used for this purpose.
  • Cooling devices are known which have adapted to the shrinkage, ring-like heat sink, which are traversed by a cooling liquid.
  • a disadvantage of these heatsinks is that they are very difficult and usually thermally ineffective adaptable to different shrinkage chuck dimensions and therefore a variety of heat sinks must be kept ready for the various shrinkage chuck.
  • direct cooling devices are known, which usually use a cooling liquid with additives intended to prevent rusting.
  • the shrinkage chuck together with inserted tool is in this case introduced into a housing, which is then sealed watertight to be flooded with the cooling liquid, as known from DE 103 20 641 Al.
  • DE 20 2004 014 564 U1 discloses an induction shrinking device in which a cooling device is integrated, wherein the shrinkage chuck is arranged in a lockable chamber.
  • the cooling device is designed here as a spray head.
  • a disadvantage of this embodiment is the integration of the induction shrink device directly into the coolant circuit. In addition, the handling of the shrink chuck is difficult in this device.
  • the shrinkage chucks also have a further problem. On the one hand, they have to be able to be positioned very accurately during the clamping of an insert tool and, on the other hand, they must also be manipulated when hot, in particular transported to a cooling device. For this purpose, a device must be provided which allows fixing and supporting the hot shrinkage chuck.
  • a further object of the present invention is to provide a receiving device in which shrinkage chucks can be positioned very precisely and which, at the same time, can be used after the tool has been clamped for transferring the shrinkage chuck into the cooling device, which also favors the cooling process and in particular has no or leaving only marginal amounts of moisture and dirt on the shrink chuck after cooling.
  • This recording device should also be usable for other tool holders such as for expansion chuck.
  • the device for cooling of shrink chucks on at least one coolant nozzle By overpressure in the supply line to the coolant nozzle, a spraying of the heated shrinkage chuck is achieved in order to lower its temperature and to allow a clamping of the inserted insert tool. As a result, a targeted and metered use of coolant is possible, so that the shrink chuck can be cooled with significantly less coolant. In addition, e.g. by interval-like switching on and off the coolant nozzle the desired cooling time and intensity can be adjusted. As a result, the cooling effect is very precisely adjustable and in particular a shock cooling is avoided.
  • Evaporated coolant may be hazardous to health due to additives such as rust inhibitors when inhaled.
  • additives such as rust inhibitors
  • continuous spraying is advantageous in the case of toxic additives, as this will cause any vapors which form to condense immediately by cooling by means of liquid coolant and to be held in the apparatus. Because of the spraying instead of flooding of an inner area, the invention makes lower demands on the sealing of the device to the outside.
  • the cooling area is provided with a container for shielding the sprayed coolant, which only has to be designed to be splash-proof to the outside, which makes a considerably less complicated sealing necessary.
  • a food einschnden for example cylindrical container made of a transparent, also impact-resistant, plastic, which is seated under gravity with its lower edge on a base plate, so that separate sealing means can be omitted.
  • a spraying of the coolant is avoided to the outside and it is sufficient to occupational safety, since the coolant is usually water with additives, especially rust inhibitors, and inhalation of vaporized additives could be hazardous to health, therefore encapsulation of the cooling device is required.
  • This container is now designed to be displaceable along the longitudinal axis of the shrink chuck.
  • a translational movement of the shrink chuck is thereby made possible, whereby the handling is simplified and the cooling device according to the invention is easier to use in a fully automatic machining center.
  • two or more coolant nozzles are arranged one above the other, whereby an extended area of the shrinkage chuck can be sprayed along the longitudinal axis, which leads to even more uniform cooling.
  • one or more air nozzles are provided for targeted blowing of the shrink chuck with the clamped tool, whereby the drying of the shrink chuck is accelerated.
  • the air nozzles can also be used for drying parts of the device, whereby in particular a dripping onto the already dried shrink chuck, in particular from the cover of the device can be avoided.
  • two or more air nozzles are arranged one above the other, since then the drying process can be accelerated.
  • the at least one air nozzle is arranged on at least one tube rotatably mounted about the longitudinal axis of the shrink chuck, wherein the tube has in particular radially to the longitudinal axis of the shrink chuck facing holes as air nozzles.
  • At this at least one tube and coolant nozzles can be arranged.
  • To monitor the Positioning of the tube may be provided a proximity switch, which prevents the tube after switching off the rotational movement remains in a forward position, where it would hinder the removal of the shrink chuck.
  • This at least one rotary tube can either be powered by its own drive, such as a motor, or directly with suitable beam guidance by the recoil of the water or the air.
  • the device has a plurality of coolant nozzles, in particular 3 or 6, which are arranged around the longitudinal axis of the shrinkage chuck to be cooled at an angle of 120 ° or 60 °.
  • a regular arrangement around the shrink chuck allows a uniform spraying or wetting of the hot shrink chuck.
  • Spraying with multiple coolant nozzles leads to faster cooling and the uniform arrangement of the coolant nozzles also prevents uneven cooling of the shrinkage chuck.
  • the air nozzles are arranged at regular angles over the circumference, in particular 3 or 6 or more air nozzles with an angle of 120 °, 60 ° or correspondingly. This ensures uniformly fast drying.
  • the device has in a particularly advantageous manner guide means such.
  • guide rods by means of which the air nozzles and / or coolant nozzles are slidably disposed along the longitudinal axis of the shrink chuck.
  • spraying along the entire longitudinal axis of the shrink chuck can be ensured without requiring a large number of coolant nozzles.
  • the coolant nozzles can be moved upwards, whereby a disability-free insertion or removal of the shrinkage chuck is made possible.
  • the shrinkage chuck change can be made easier, which increases the integrability of the device for cooling in eg a machining center.
  • advantageously displaceable coolant nozzles can be combined with arranged in a rotatable tube air nozzles or even slidable air nozzles with arranged in a rotatable tube coolant nozzles.
  • annular sprinkler system which has at its inner diameter a plurality of coolant nozzles and / or air nozzles, whereby at only one point of the sprinkler system storage must be mounted on a guide rod to the sprinkler system with all attached thereto coolant nozzles and / or air nozzles to move vertically.
  • Both the air nozzles for drying the shrinkage chuck and the air nozzles provided for drying the container are preferably oriented so that they are not perpendicular with respect to the gravitational attraction but partly in the direction of gravitational attraction, that is to say with an angle downward. Then, airflow and gravity are advantageously superimposed for faster drying.
  • the air nozzles for drying the shrinkage chuck do not blow radially on this but are offset parallel to this radial orientation in the direction of a tangential alignment. Thus, they can be aligned both along a secant and directly tangentially with respect to the shrink chuck cross section. This results in even faster drying, since no dynamic pressure generated at the shrinkage lining surface and also the moisture is partially demolished by the secant or tangential inflow of air from the shrinkage chuck.
  • certain air nozzles be provided a secant-like orientation, ie an orientation that is not in a plane in which the longitudinal axis of the container is arranged, but an orientation parallel offset to this longitudinal axis, ie along a secant of the container cross-section.
  • the sprayed coolant is preferably collected in a collecting means at the lower portion of the coolant device, thereby a closed circuit can be produced, which reduces the consumption of coolant.
  • the coolant nozzles and / or air nozzles can be fastened to the collecting means via holding means.
  • Such a type of fastening is characterized by constructive simplicity and high stability.
  • neither coolant nozzles nor air nozzles are attached to the container, since then no coupling elements for the operation of these nozzles must be provided on the displaceable container.
  • an air nozzle or a coolant nozzle blowing down vertically into the container can be provided, whereby a direct air flow is produced for drying on the shrink chuck or a cooling jet for cooling.
  • a fan may be provided, which is arranged in a conically narrowing housing on the container wall, so that an air flow enhancement is effected and the drying is very efficient.
  • the device has a receiving means for shrinkage chuck, wherein this receiving means is annular and has a receptacle formed within an inner diameter, wherein the inner diameter evenly spaced balls are arranged. It can z. B. 3 or 6 balls may be arranged at an angle of 120 ° or 60 ° at the inner diameter.

  • the balls are arranged in pairs one above the other, thereby avoiding entanglement of the shrinkage chuck within the receiving means.
  • the apparatus comprises means for measuring temperature, in particular optical temperature measuring means or contact measuring means, whereby e.g. the duration of the spraying with coolant can be regulated.
  • Temperature measurement of individual areas of the shrink chuck can also be used to spray individual areas of the shrink chuck at particularly high temperatures for longer than other rather cold areas. As a result, an adjustability and a metered use of the coolant is achieved, which in turn reduces the coolant required and tensions due to uneven cooling can be avoided.
  • mold recognition sensors can be provided, with the aid of which the coolant nozzles can be selectively moved and thereby only the heated areas of the shrinkage chuck are cooled on the shrink-fit head.

Also, a flow of air can blow this coolant almost unhindered by the shrinkage chuck.
