Description

Technical Field

[0001] The utility model relates to the field of aluminum material processing, in particular to a material ejecting device for hot shearing of aluminum bars. Background Art

[0002] At present, the extrusion production process of industrial aluminum profiles is generally as follows: 1) melting aluminum ingots and casting them into long aluminum bars with a length of about 6 to 8 meters, 2) heating the aluminum bars and cutting them according to the amount of profiles, and 3) feeding the short aluminum bars into the extruder to extrude the profiles. The existing known technology and current status of the extruder is a fixed extrusion rod movable crossbeam, which requires a space with the maximum length of aluminum bars that can be used by the extruder to feed the bar material. There are many deficiencies, defects and disadvantages, such as the large body length of the extruder, the short length of the aluminum bars that can be used, the long reactive production time, the low yield rate of aluminum materials produced, the low production capacity, and the high cost of mechanical manufacturing materials. To solve the above problems, the Chinese invention patent with patent publication number CN105583248B provides a mobile extrusion rod structure. The present invention is provided with a hydraulic cylinder 7. Under the action of the hydraulic cylinder 7, the extrusion rod structure can be moved left and right, so that after the extruder quickly retreats into place, the mobile extrusion rod structure quickly moves laterally (i.e., moves to the left) to make room for the aluminum rod to enter and exit, thereby increasing the usable length of the aluminum rod by 20%, increasing the aluminum production yield by 5%, increasing production efficiency by 15-20%, and reducing the cost of machinery manufacturing materials by 3-8%.

[0003] However, the above structure can only be used in the situation of retreating and avoiding when loading and unloading aluminum bars. In fact, due to the diversified production sizes of aluminum bars, precise alignment is required before and after loading, that is, the center line of the extrusion rod and the center line of the aluminum bar need to be consistent. The transmission accuracy of the above structure transmission method is not enough, it is difficult to ensure the processing quality of the aluminum bar, and the scope of application is narrow.
