Description

Technical Field

[0001] The utility model relates to the field of galvanized iron tower production, in particular to a punching and shearing device for angle steel. Background Art

[0002] Galvanized steel towers are also called angle steel towers. Angle steel towers are generally used as supporting structures for power transmission lines and communication lines. They can withstand a certain amount of weight and wind pressure. Due to the high strength and stability of angle steel, angle steel towers have good structural stability and earthquake resistance, and are particularly suitable for power transmission lines in mountainous areas and complex terrains. Since the punching and shearing of angle steel is mostly done on a single piece, the efficiency of a single machine is low, and the angle steel needs to be displaced during the punching and shearing process to meet the requirements.

[0003] After searching, the Chinese patent announcement number is CN217964277U, which discloses a precision punching machine for angle steel tower production. The patent uses an electric lifting rod to push the connecting plate so that the cutter cuts the angle steel, and the cut angle steel is sent to a collection box. The device has certain problems in the punching and shearing of angle steel: there are burrs on both ends of the angle steel after punching and shearing. Usually, the two ends of the angle steel need to be manually polished after cutting, which is a cumbersome process and relatively labor-intensive. Utility Model Content
