Fuel gas type universal rapid aluminum bar heating system for long bars and short bars

Abstract

The invention relates to the technical field of aluminum bar heating, in particular to a fuel gas type universal rapid aluminum bar heating system for long bars and short bars. The fuel gas type universal rapid aluminum bar heating system comprises a feeding unit, a heating unit and a peeling and shearing unit. The feeding unit, the heating unit and the peeling and shearing unit are sequentially connected through a conveying roller way. The peeling and shearing unit comprises a power aluminum bar conveying roller way. The other end of the power aluminum bar conveying roller way is connected with a hot shearing machine. A short bar conveying mechanism is connected beside the hot shearing machine. A hot peeling machine is arranged beside the power aluminum bar conveying roller way. A short bar pushing mechanism is arranged between the hot peeling machine and the power aluminum bar conveying roller way. A three-station gantry manipulator is arranged above the power aluminum bar conveying roller way, the hot peeling machine and the short bar pushing mechanism. By the adoption of the structure, the fuel gas type universal rapid aluminum bar heating system for long bars and short bars is high in mechanization degree and low in labor intensity; long bars and short bars can be replaced rapidly, energy consumption is low, the technological applicability is high, the fuel gas type universal rapid aluminum bar heating system is particularly suitable for production of various types of aluminum alloy and industrial aluminum products of various specifications and lengths, and the production yield is high.

Description

technical field [0001] The invention relates to the technical field of aluminum rod heating, in particular to a gas-fired general-purpose rapid aluminum rod heating system for long and short rods. Background technique [0002] Currently, if Figure 5a and Figure 5b As shown, in the extrusion production of industrial aluminum profiles, the long aluminum rod 502 is generally heated by a gas-fired rapid furnace, and the aluminum rod is cut by the scissors 501 of the thermal shearing machine, so as to obtain the high-temperature short aluminum rod required for extrusion production. Rod 503. 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 502 is hot-sheared...

AI Technical Summary

Problems solved by technology

Because after the long aluminum rod 502 is hot-sheared, the high-temperature short aluminum rod 503 obtained has large deformation at the end, and the deformation 504 is formed by bending in the longitudinal direction, which makes the thermal peeling machine unable to peel. Therefore, these two processes, namely "long aluminum rod" Rod heating + thermal shearing process" and "short rod heating + thermal peeling process" are on the same gas-fired rapid heating furnace to provide high-temperature short aluminum rods that meet the requirements that cannot be used universally on the same extrusion machine

[0003] Chinese invention patent CN103375988A discloses a fully automatic aluminum rod heating furnace. There is an insulating layer on the outside of the furnace inside the furnace body. The inlet of the furnace is connected to the feeding mechanism. The chain on the wheel runs through the furnace, the driving device drives the sprocket to rotate, the air outlet of the suction fan communicates with the furnace, and there is a smoke exhaust chimney connected to the outside on the furnace, and the high end of the connecting plate is aligned with the chain at the furnace outlet. The bottom end of the plate is connected to the high end of the feeding channel, the bottom end of the feeding channel is connected to the discharge chute, and the discharge chute is just connected to the feed port of the aluminum extrusion machine. The controller controls the action of the feed mechanism and the driving device. 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 universal heating of long and short rods or skinned
