Description

Technical Field

[0001] The utility model relates to the field of aluminum material processing, in particular to a top pressing 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 meters to 8 meters, 2) heating the aluminum bars according to the amount of profiles and then cutting and dividing them, and 3) feeding the short aluminum bars into the extruder to extrude the profiles. In step 2), aluminum bar hot shearing equipment is usually used for cutting, but the existing aluminum bar hot shearing equipment is set on one side of the extruder, and the scissor blades on the aluminum bar hot shearing equipment are set in a vertical direction to repeatedly cut the aluminum bar. Based on this, the existing aluminum bar hot shearing equipment has the shortcomings, defects and disadvantages of excessive wear and damage of the scissor blades when the scissor blades rub too many times and the friction frequency is too fast. In order to solve the above problems, the Chinese utility model patent with patent publication number CN214109037U provides a structure to reduce the wear of scissors. By designing "scissor seat oil cylinder", "scissor seat transverse oil cylinder" and "scissor seat suspension", the scissor blades are separated from the aluminum bar section after the shearing is completed, avoiding contact with the aluminum bar shearing surface, thereby reducing the friction of the aluminum bar on the scissor blades and effectively protecting the wear of the scissor blades.

[0003] However, although the above structure prolongs the service life of the scissor blades, due to the hard texture of the aluminum bar, during the cutting process, especially at the moment when the scissor blades touch the aluminum bar, the aluminum bar is easily shaken and rebounded by the impact of the scissor blades, which seriously affects the cutting effect. Therefore, it is necessary to design a device that can press the outer periphery of the aluminum bar during the cutting process, so as to reduce the shaking caused by the impact of the aluminum bar and improve the cutting quality.
