Description of the Invention: [Technical Field] The present invention relates to a device for heat treating a sheet material, comprising a continuous furnace heated by a burner and a sheet conveying device. [Prior Art] The manufacture of lightweight structural members from high-strength sheets, particularly in the manufacture of bodies for vehicles, is conventionally practiced in that the sheets are heated from hardenable steel to, for example, 95 。. The melting heat of C is then deformed in a press and hardened due to the rapid cooling of the cooled model tool. In the heat treatment of such sheets, a continuous furnace heated by a burner is used. The heat-treated sheet is conveyed by means of a conveyor through a continuous furnace, through a continuous furnace, in a given heat energy, and in a case where the sheet is conveyed through a continuous furnace, the furnace needs to have a fixed length to heat the sheet to The processing temperature is maintained at the processing temperature for a predetermined period of time. However, often due to limited space configuration in the manufacture of such styling members, a shorter furnace is required, without low economic efficiency and high thermal power. cost. This creates a design cost due to the condition that the sheet to be treated is automatically fed to the continuous furnace in the furnace feed zone, and the automatic handling of the sheet in the opposite furnace discharge zone after heating. SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a device for heat treatment of a sheet of the aforementioned type which, in the case of an advantageous energy use, enables the sheet to be subjected to the necessary necessity in a continuous furnace having a short length. Heat treatment. The method for achieving the purpose is that the burner is separated from the heating chamber and the preheating chamber. The burner is provided below the heating chamber, and the chamber and the heating chamber are separated by an intermediate partition. The gas through hole is also characterized in that the conveying device comprises: a conveyor passing through the preheating chamber and a conveyor arranged through the upper and lower sides and passing through the heating chamber, and the second conveyor reading shirt is opposite to the conveying direction of the conveying chamber with the working room, and Conveying 4 201144735 The speed is half of the speed of the conveyor in preheating to the middle, and also between the conveyor discharge of the preheating chamber and the feeding of one of the heating chambers, with a distribution device, To distribute the plates. The continuous furnace is divided into a lower heating chamber having two conveyors arranged above and below, and an upper preheating chamber, and the plate is introduced through the upper preheating chamber. This division can significantly shorten the length of the continuous furnace, and is not only due to the parallel introduction of the plates. The preheating chamber and the heating chamber are also in particular due to a reduced conveying speed in the conveyor zone of the heating chamber in the two parallel guides. Since the sheet is in the heating chamber area due to the selected conveying speed ratio, the residence time in the heating chamber is twice the residence time in the preheating chamber, and although the furnace length is short, the favorable conditions for the heat treatment are ensured. It is only necessary to note that the preheating plates conveyed by the conveyor through the preheating chamber are mutually unloaded to the second conveyor passing through the heating chamber, which ensures that the design is achieved with a small design, as long as the conveyor outlet and the heating chamber in the preheating chamber are A plate dispensing device may be provided between the conveyor inlets. On the one hand, due to the conveying device in the opposite direction of the conveyor of the preheating chamber and on the other hand, the conveyor of the heating chamber, the feeding inlet of the conveyor of the preheating chamber, and the outlet of the conveyor of the heating chamber are located on the same side of the furnace. The same handling device can be used for feeding and discharging the continuous furnace and the heated plate, and the handling robot is used in the first place, which not only reduces the design cost, but also reduces the device and space requirements. < separating the preheating chamber from the heating chamber below it via an intermediate partition having a flue gas through hole, which has the advantage that the sheet can be accessed from the heating chamber via the helium through hole in the preheating chamber The flue gas in the preheating chamber is preheated with sensible heat to produce excellent thermal energy utilization. The combustion air introduced into the burner of the heating chamber can be preheated by means of a heat exchanger by means of flue gas drawn from the preheating chamber. The burner opening of the heating chamber is in the space between two heating machines designed as roller conveyors, and the plate can be placed not only on the roller conveyor below the burner, but also on the roller conveyor above the burner. , is heated evenly until the flue gas exits the heating chamber through the fumes through the 201144735 spacer. There are a number of different solutions for the design of the sheet distribution device at the end of the furnace at the feed of the preheating chamber conveyor. The only condition is that the preheated sheet from the preheating chamber conveyor is unloaded to the heating chamber in an interactive manner. The second conveyor. A particularly simple design consists in that the sheet dispensing device comprises a conveyor in the insulated casing which is attached to a pusher for height-adjustable positioning and for changing its conveying direction. In this embodiment, the conveyor of the dispensing device is positioned only between the individual conveyor planes, and the sheeting on the conveyor plane of the preheating chamber conveyor is lowered to the conveyor plane of the selected heating chamber conveyor, and The sheet is handed over to the conveyor. The insulated enclosure of the dispensing unit protects the heated panels from being cooled during transfer to the heating chamber conveyor. [Embodiment] The apparatus shown includes a continuous furnace 1 partitioned by an intermediate partition 2 into a lower heating chamber 3 and an upper preheating chamber 4. The preheating chamber 4 is passed through by a roller conveyor 5. The heating to 3 has two conveyors 6 and 7 arranged one above the other, the conveying direction of which is opposite to the direction of the conveyor 5 of the preheating chamber 4, and the conveying speed is equivalent to one half of the conveying speed of the conveyor 5 passing through the preheating chamber 4. The heating chamber 3 is provided with a burner 8 which opens to the heating chamber 3 in the middle between the roller conveyors 6 and 7. At the opposite end of the continuous furnace 1 of the feed station 9 of the conveyor 5 of the preheating chamber 4, a distribution device 1 is provided, which is distributed by the heat-treated sheet 11 conveyed by the conveyor 5 of the preheating chamber 4. The dispensing device is located within a thermally insulated housing 12. In the illustrated embodiment, the dispensing device 1' has a reversible conveyor 13' mounted to slide along the rail 14 at a height and to contact a pusher (not shown) so that it is also designed The conveyor 13 of the roller distribution device 10 can be positioned on individual conveying planes of the conveyors 5, 6, 7 passing through the preheating chamber 4 and the heating chamber 3. In the receiving position indicated by the solid line, the conveyor 13 of the dispensing device 10 is located on the plane of the conveyor 5 of the preheating chamber 4, and the preheated sheet 11 in the preheating chamber 4 is sent to the conveyor 13 through 6 201144735. After the conveyor 13 is lowered and the conveying direction is switched, the material is alternately delivered to the conveyors 6, 7 disposed above and below the heating chamber 3. In the heating chamber 7, the plates u on the two conveyors 6, 7 are heated by means of the flue gas of the burner 8 to the desired processing temperature until they are discharged from the continuous furnace 1 at the discharges 15 of the conveyors 6, 7 It is shipped and delivered to, for example, a forming press via a suitable processing device. The feed point 9 of the conveyor 5 of the preheating chamber 4 and the discharge point 15 of the conveyors 6, 7 of the heating chamber 3 are located on the same side of the furnace, on the feed to the continuous furnace, and after the heat treatment. On the unloading, it is not necessary to separately use the processing device. In the intermediate partition 2, a flue gas through hole 16 is provided, and the flue gas of the heating chamber 3 can be drawn into the preheating chamber 4 through the flue gas through hole 16', and the sputum is The preheating chamber 4 preheats the sheet 11 by means of flue gas from the heating chamber 3. To ensure the desired flow of flue gas, the flue gas through hole 16 can be opened differently along the length of the preheating chamber 4 inside the preheating chamber 4. The flow cross-sectional area is preferably adjusted to match the adjustable flue gas through hole.
