Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum rod heating furnace, in particular to a one-out-four extrusion matched rotary aluminum rod heating furnace. BACKGROUND

[0002] Aluminum extruded profiles are widely used in the fields of construction, transportation, electronics, and machinery manufacturing due to their light weight, high strength, corrosion resistance, and ease of processing. In order to ensure the smooth forming of aluminum extruded profiles during extrusion and achieve the required mechanical properties, aluminum rods usually need to be heated before extrusion to reach the appropriate processing temperature. The one-out-four extrusion matched rotary aluminum rod heating furnace is a heating equipment that integrates heat, machinery, automation control, and temperature measurement. It uses hot air circulation heating and other new technologies, has the characteristics of fast heating speed, flexible production organization, high automation degree, simple operation, and low energy consumption. The aluminum rod can be placed in the storage rack by forklift or crane, and about 17 rods can be stored. The aluminum rods can be rolled in the axial direction of the rod rack and fall on the roller rack, and finally pushed into the furnace by the rod pushing machine. The aluminum rods are arranged in a circle in the furnace. The rotary aluminum rod heating furnace can ensure the continuity of the extrusion operation and the process temperature requirement of the aluminum rod from entering the furnace to exiting the furnace.

[0003] However, the existing rotary aluminum rod heating furnace has some shortcomings in use: the traditional rod storage rack does not have a preheating function, which causes the aluminum rod to have a low temperature before entering the heating furnace, increases the burden of the heating furnace, prolongs the heating time, and reduces the overall production efficiency. In addition, the existing feeding method mainly relies on the rod pushing machine to push the aluminum rod into the heating furnace, which requires multiple steps in the operation process, and the process is complex and inefficient. Because the aluminum rod is in contact with the transmission structure for a long time during feeding, heat conduction causes the transmission structure to be easily damaged, increasing the maintenance and replacement cost of the equipment. The traditional feeding method is difficult to achieve continuous feeding, which may cause interruption in the production process, affecting the continuity and stability of the extrusion process.

[0004] Therefore, the existing problems are researched and improved, and the one-out-four extrusion matched rotary aluminum rod heating furnace is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology. SUMMARY
