Description

technical field [0001] The invention belongs to horizontal extruder equipment and auxiliary devices used in the extrusion processing industry of aluminum and aluminum alloys, in particular to a short-stroke aluminum extruder front feeding system and a clamp-type self-adaptive ingot supply device. Background technique [0002] Aluminum alloy extruded profile is an ultimate formed product with good processing plasticity, high strength, light specific gravity and high recycling rate. It is a widely used metal material. At present, as aluminum profiles enter the field of civil construction, replacing traditional steel-wood doors and windows, and are widely used in industrial fields such as high-speed trains and urban rail transit vehicles, automobiles, and container bodies, the aluminum extrusion processing technology is constantly being promoted. Development and progress have led to the continuous development of large-scale aluminum extrusion machines, with more and more functi...

AI Technical Summary

Problems solved by technology

[0007] 1) Due to the location of the ingot feeder, the opening size of the extruder frame is relatively large, which makes the structural strength and overall rigidity of the press lower, and affects the guiding accuracy of the extrusion beam and extrusion cylinder, which is not conducive to extrusion Improvement of precision of pressed products

[0008] 2) The stroke of the extrusion rod is longer, which increases the volume of oil in the main cylinder and the time for raising and releasing pressure. At the same time, it relatively increases the wear of the seal, guide sleeve and guide plate, and is not conducive to the alignment during extrusion

[0009] 3) The aluminum ingot cannot be positioned on the center line of the extrusion cylinder, and the extrusion rod has eccentric load

When the extrusion rod is filled and extruded, the force is unbalanced, resulting in a considerable upward bending eccentric force, which affects the life of the extrusion rod

[0010] 4) The non-extrusion cycle time of the extrusion machine is long, so that the power consumption of the entire extrusion production line is large and the production efficiency is low
