The working principle is as follows:
when the aluminum bar needs to be heated, the aluminum bar is hoisted to the storage rack through the travelling crane, and the aluminum bar rolls towards the bar feeding rack in sequence under the action of the gravity of the aluminum bar due to the inclined plane of the bar holding surface of the storage rack and is blocked by the blocking surface of the bar lifting rack of the bar lifting mechanism; the initial position of a rod lifting hook of the rod lifting mechanism is positioned right below the aluminum rod at the position of the material blocking surface, and the rod lifting hook lifts the aluminum rod upwards under the driving of a hydraulic motor; the rod lifting hook can only lift one aluminum rod each time, even if a plurality of aluminum rods are stacked at the position of the material blocking surface, the stacked aluminum rods can roll down onto the material storage rack again in the lifting process of the rod lifting hook; the rod lifting hook drives the aluminum rod to be gradually lifted upwards under the action of the chain and gradually overturned at the position of the upper chain wheel, so that the aluminum rod is overturned onto the rod feeding roller; the buffer mechanism on one side of the rod feeding roller is used for supporting the aluminum rod when the rod lifting hook overturns the aluminum rod, so that the aluminum rod is prevented from directly overturning and falling onto the rod feeding roller to damage the roller; the initial position of the buffer hook is slightly higher than the rod feeding roller, the aluminum rod overturned by the rod lifting hook is supported, then the first cylinder drives the buffer hook to slowly fall down, and the aluminum rod is lightly placed on the rod feeding roller; after the aluminum bar on the bar feeding roller is fed into the heating furnace, the lifting hook continues to move to the initial position along the chain, and the next bar lifting operation is started.
The traditional aluminum bar is mainly fed into the heating furnace in two ways: one is a push rod mode, which has a long length and occupies too much space; the other is that the rod feeding roller is provided with power, and the rod feeding roller in the heating furnace is also provided with power, so that the method increases the equipment cost on one hand, and increases the heat transfer of the furnace body and the energy consumption on the other hand. According to the aluminum bar feeding device, the bar pressing mechanism is arranged at the front end of the bar feeding rack, an aluminum bar is slowly fed into the heating furnace under the action of the feeding roller of the bar feeding rack, when the front end of the aluminum bar is detected by the photoelectric switch at the rear side of the bar pressing mechanism, the bar pressing mechanism is pressed down in a delayed mode to press and fix the front end of the aluminum bar, the friction force between the bar pressing mechanism and the bar feeding roller can be improved, and the aluminum bar can be smoothly fed into the heating furnace even if the aluminum bar is bent to a certain degree; when the rear end of the aluminum rod is detected by a photoelectric switch at the rear side of the rod pressing mechanism, the rod pressing mechanism is opened, the second aluminum rod is lifted to the rod feeding roller wheel and conveyed forwards under the action of the rod feeding roller wheel, after the front end of the second aluminum rod is detected by the photoelectric switch, the rod pressing mechanism is pressed down in a delayed mode to fix the front end of the second aluminum rod, the first aluminum rod is pushed under the action of the rod feeding roller wheel to continue to be conveyed into the heating furnace, after the first aluminum rod completely enters the heating furnace, the second aluminum rod exits the heating furnace backwards under the action of the rod feeding roller wheel, the furnace door of the heating furnace is closed to heat the aluminum rod, and the rod feeding heating operation of the aluminum rod is completed in sequence in a circulating and reciprocating mode.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
