Description

Technical Field

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

[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 and cutting the aluminum bars according to the quantity of profiles for material distribution, and 3) feeding the short aluminum bars into an extruder to extrude profiles.

[0003] On existing hot shearing equipment for aluminum bars, the scissors blades are long-term set on one side of the extruder in a vertical reciprocating reset working state to repeatedly cut aluminum bars. Based on this, existing hot shearing equipment for aluminum bars has the deficiencies, defects and drawbacks that when the friction times and frequency of the scissors blades are excessive, it will cause excessive wear and damage of the scissors blades. To solve the above problems, the Chinese utility model patent with the patent publication number CN214109037U provides a structure for reducing scissors wear. By designing a "scissors seat oil cylinder", a "scissors seat horizontal oil cylinder", and a "scissors seat suspension", the scissors blades leave the cross-section of the aluminum bar after shearing is completed, avoiding contact with the shearing surface of the aluminum bar, thereby reducing the friction of the aluminum bar on the scissors blades and effectively protecting the wear of the scissors blades.

[0004] However, although the above structure extends the service life of the scissors blades, the working state of the scissors blades reciprocating in the vertical direction for a long time exists. Due to the lack of a guiding structure for the scissors blades, the scissors blades vibrate during the working process, affecting the cutting effect. In addition, the scissors blades are consumable parts after all. The existing installation method of the scissors blades is to fix the scissors installation position of the scissors seat by welding, resulting in inconvenient disassembly, replacement of the scissors blades, increasing the maintenance time and reducing the production efficiency.

[0014] Optionally, the residual oil cleaning mechanism further includes a photoelectric switch for detecting the descending position of the scissors residual oil cleaning and pressing rod, and the photoelectric switch is arranged on the residual oil cylinder mounting block.
