Description

technical field [0001] The invention relates to the technical field of aluminum material processing, in particular to a fully automatic short aluminum rod heating production line and a method thereof. Background technique [0002] At present, in the extrusion production of industrial aluminum profiles, a gas-fired rapid furnace is generally used to heat the long aluminum rods, and the aluminum rods are cut through the scissors of the hot shears, so as to obtain the high-temperature short aluminum rods required for extrusion production. When the quality of industrial aluminum profiles is high, the gas-fired rapid furnace is used to heat the short aluminum rods, and the outer diameter of the aluminum rods is stripped by 3-5mm through the thermal peeling machine, so as to obtain the high cleanliness required for extrusion production High temperature short aluminum rod. Because after the long aluminum rod is hot-sheared, the high-temperature short aluminum rod obtained has larg...

AI Technical Summary

Problems solved by technology

This kind of rotary heating furnace mainly has the following disadvantages: since a whole casing is used to cover the aluminum rod, it is difficult for the hot air burning in the furnace to directly heat the aluminum rod, even if a through hole is opened on the casing, The area of ​​the hot air directly heating the aluminum rod is still limited, so this will affect the heating speed of the aluminum rod, and the heating of the aluminum rod takes a long time; during the whole heating process of the aluminum rod from the furnace to the furnace, the aluminum rod follows the turret It rotates once and is always supported by the casing. In this way, the aluminum rod is statically rubbed against the casing when it enters and exits the casing. The resistance of the aluminum rod entering and leaving the casing is large and not smooth. A large-power feeding mechanism is required to complete the push of the aluminum rod.

[0004] Chinese invention patent CN 103375988 A discloses a fully automatic aluminum rod heating furnace. There is an insulation layer on the outside of the furnace inside the furnace body. The inlet of the furnace body is connected to the feeding mechanism. The chain on the sprocket runs through the furnace, and the driving device drives the sprocket to rotate. The air outlet of the suction fan communicates with the furnace. , the bottom end of the connecting plate is connected with the high end of the feeding channel, the bottom end of the feeding channel is connected with the discharge chute, and the discharge chute is connected with the feed port of the aluminum extrusion machine correspondingly, and the controller controls the feed mechanism and the driving device Action, the invention realizes the automatic input of aluminum rods to the inner diameter of the furnace for heating and then output to the aluminum extrusion machine for aluminum extrusion, the whole process does not need manual operation, which improves the production efficiency; however, this invention cannot realize the aluminum rods Automatic feeding and stable movement in the heating furnace, also can not achieve universal heating of aluminum rods

[0005] The aluminum rod heating furnace is used for heating and forging of aluminum profiles. The short rod furnace is to cut the long aluminum rod into the required short aluminum rod, heat it to the extrusion temperature (420-520 ℃) ​​through the short aluminum rod heating furnace, and then supply it for extrusion. The machine is used. At present, a single-door box-type aluminum rod heating furnace is generally used. The workpiece is heated in the heating furnace. When the temperature reaches the temperature and can be processed, the workpiece is taken out. Because it is a single-door box type, the entire furnace door needs to be opened when taking the workpiece. , resulting in a large amount of heat loss in the heating furnace and high energy consumption; if it is necessary to reheat the second workpiece, it is necessary to close the furnace door and heat up again, so that the temperature in the heating furnace returns to the original set temperature state, and the heating furnace Only after all the workpieces are completed can new workpieces be added for heating, resulting in a long processing cycle of the workpieces and affecting the quality of the same batch of workpieces

[0006] At present, the short rod furnaces produced in China are generally driven by chains or rollers, the furnace door cannot be completely closed, the heat loss is large, and the number of aluminum rods in the furnace is limited. In order to achieve production capacity, the rapid heating method is adopted, which consumes a lot of energy. About 70m3 natural gas, and the aluminum rod needs to be homogenized first, which is costly
