Definitions

  • the invention relates to a device for transporting metallic workpieces, in particular during a heat treatment process.
  • Such a device is known, for example, from EP 1 229 137. It serves to transfer metallic workpieces between individual heat treatment chambers, which can be approached in a predeterminable sequence as part of a heat treatment process and loaded and unloaded via the transport device.
  • the device for transporting is equipped with a transport chamber which is thermally insulated and vacuum-tight. Heat treated workpieces can thus be removed from the heat treatment chamber without the disturbing influence of incalculable external influences, transferred to the transport chamber and transported for further treatment to another heat treatment chamber.
  • the transport chamber of the above-described transport device is designed for the hot transport of heat-treated workpieces.
  • the transport chamber by means of a designated cooling fan is first to cool.
  • the transport chamber is to be set under atmospheric pressure, so that the cold batch can be introduced into the transport chamber.
  • the transport chamber is then to be heated and evacuated, so that after completion of the treatment process within the first heat treatment chamber, a transport of the treated workpieces to the next heat treatment chamber, free from external influences, can take place.
  • the transport chamber for the re-admission of a cold batch must be cooled accordingly and brought to atmospheric pressure.
  • the invention proposes a device for transporting metallic workpieces, in particular during a heat treatment process, comprising a heat-insulated and vacuum-tight transport chamber for hot transports, a transport device for cold transports, a first movably arranged chassis for the transport chamber and a second movable arranged chassis for the transport device and a common drive for the transport chamber and the transport device, wherein the two chassis are coupled to each other.
  • the proposed transport device has a transport chamber for hot transport on the one hand and a transport device for cold transports on the other.
  • Cold batches to be transported can thus advantageously be transferred by means of the transport device, so that it is not necessary for the transport of a cold batch to cool the transport chamber and bring it to atmospheric pressure.
  • the device according to the invention thus allows both the transport of cold and hot batches, whereby a simultaneous use of transport chamber and transport device can be done.
  • the particular advantage of the device according to the invention lies in the possibility of being able to differentiate between hot transport on the one hand and cold transport on the other hand. Only cold workpieces can be transported in a simple manner, without it being necessary for this purpose to first shut down a heated and under vacuum transport chamber, ie to cool and bring to ambient pressure. This saves not only energy but also time, especially with regard to the necessary subsequent to a cold transport reheating and evacuation of the transport chamber, so that the device of the invention overall a significantly increased transport capacity is achieved. In addition, a simultaneous transport of hot and cold batch can take place with the device according to the invention, whereby a further transport capacity increase can be achieved.
  • a common drive for loading or unloading either the transport chamber or the transport device, it is only necessary to move the device according to the invention correspondingly far, so that as needed, the transport device or the transport chamber can be coupled to the respective treatment chamber. It is of course also possible, in a first step, to couple a treatment chamber to the transport chamber and, in a second step, to move the device only so far that one and the same treatment chamber can then be coupled to the transport device.
  • the device has a first movably arranged chassis for the transport chamber and a second movably arranged chassis for the transport device, wherein it is preferably provided that the first chassis for this purpose relatively movable arranged support frame for the transport chamber and the second chassis for this purpose relatively movable having arranged support frame for the transport device.
  • two separate chassis are provided.
  • Advantages of this embodiment is the ability to couple different chassis by combining together. This is particularly advantageous in terms of retrofitting since this type of configuration allows the connection of an already existing device, which has only one transport chamber for heat transport, with a transport device of the type described above.
  • a transport device to be assembled as required has, for example, a transport chamber and a total of two transport devices, wherein the two transport devices are arranged left and right of the transport chamber, so that overall results in a device for transporting metallic workpieces having a centrally disposed between two transport devices transport chamber.
  • the individual chassis can be coupled to each other in a conventional manner, wherein it is preferably provided that the chassis carrying the transport chamber has a corresponding drive.
  • This chassis can insofar be referred to as a pulling device, whereas the coupled and not having a separate drive chassis for the transport device serve as a hitch.
  • the device has a movably arranged chassis.
  • the device according to the invention has a common chassis for both the transport chamber and for the transport device.
  • the chassis is thus according to this embodiment, an overall frame, which can be made in particular cost.
  • relatively movable trained support frames for the transport chamber on the one hand and the transport device on the other are arranged on this common frame.
  • the transport chamber and the transport device can be moved independently of each other relative to the chassis, whereby a needs-oriented orientation of either the transport chamber or the transport device relative to the respectively approaching transport chamber is made possible.
  • a common drive or a separate drive for a method of the transport chamber or the transport device relative to the chassis can be provided depending on the embodiment, either a common drive or a separate drive.
  • a respective separate drive for a method of the support frame relative to the respective chassis is provided, because this creates a simplified coupling possibility.
  • the transport chamber and the transport device are each equipped with a separate charging system. Described is a corresponding charging system in EP 1 229 137, to which reference is expressly made at this point.
  • the transport device is a transport chamber.
  • Transport chambers also use as a transport device, all means for heating or evacuation of the transport chamber can be omitted. Also, it is not necessary to provide a drive unit, since the further serving as a transport device for cold batches transport chamber is to be coupled to a transport chamber provided with a drive.
  • the invention also proposes a plant for heat treatment, in particular metallic workpieces, having a plurality of separately arranged treatment chambers, this plant comprising transport devices of the aforementioned type. Enabled by such systems a simplified and less time-consuming and costly process implementation for the heat treatment of metal workpieces. It is envisaged that the transport chamber and the transport device can be loaded and unloaded independently of each other, so that either the transport chamber or the transport device can either be moved up to a treatment chamber and loaded or unloaded, depending on the procedure.
  • the transport device is designed to be loading and unloading on both sides.
  • This embodiment is particularly advantageous if treatment chambers are arranged on both sides of the travel path for the transport device, so that it is possible without complicated maneuvering to use one and the same transport device for loading or unloading the treatment chambers arranged on both sides.
  • FIG. 1 shows a device according to the invention.
  • Fig. 1 Shown in Fig. 1 is an inventive device 1 for transporting particular metallic workpieces.
  • the device 1 comprises on the one hand a heat-insulated and vacuum-tight formed transport chamber 2 for hot transports and on the other hand, a transport device 3 for cold transports. Worn are the transport chamber 2 of a chassis 5 and the transport device 3 of a chassis 4.
  • a hinged Lostician 6 the two chassis 4 and 5 are coupled together, so that a total of a common chassis unit is formed.
  • the articulated Lostician serves to compensate for unevenness of the rails, so that it is ensured in any case that the chassis 4 and 5 carrying rollers 7 in any case have contact with the rail 8.
  • chassis 4 and 5 can also be provided for the transport chamber 2 and the transport device 3 a common Provide chassis, which then carries both the transport chamber 2 and the transport device 3.
  • the device 1 according to the invention is driven by means of a drive not shown in detail in FIG. 1, which is part of the chassis 5 carrying the transport chamber 2.
  • This chassis 5 thus serves as a pulling device for the chassis 4, which can be referred to as a trailer device due to the force-transmitting coupling.
  • the particular advantage of the device according to the invention is that the arrangement of a transport device serving only cold load transport creates the possibility of not having to heat and cool the transport chamber 2 designed for transporting heat continuously. It is also unnecessary with the additional use of the transport device 3 a repeated evacuation of the transport chamber 2, which is advantageously not only energy but also time-saving.
  • a loading system in the form of a pressure chain 9 is provided for loading and unloading of the transport device 3.
  • This advantageously enables easy loading of the receiving means 3, preferably designed in the form of a loading table, whereby the pressure chain 9 is preferably arranged in such a way that loading and unloading of the transport device 3 on both sides is possible.
  • batch guides 10 are provided with inlet slopes.
