Angle steel opening and closing angle die

Abstract

The invention discloses an angle steel opening and closing angle die, which is formed by an upper die and a lower die; the upper die and the lower die are matched with each other; the upper die comprises an L-shaped upper press plate; the insides of two edges of the upper press plate are respectively connected with an upper die holder by an upper die adjusting device; the lower die comprises an L-shaped lower press plate; the outsides of two edges of the lower press plate are respectively connected with a lower die holder by a lower die adjusting device. The angle steel opening and closing angle die is suitable for the opening and closing angles of angle steel with different angles by adjusting angles of the L-shaped upper and lower press plates; the maximum closing angle can be 60 degrees; the maximum opening angle can be 40 degrees; the replacing and mounting time is saved, the work efficiency is improved, the operating difficulty and intensity are greatly reduced and the labor production efficiency is obviously improved.

Description

technical field [0001] The invention relates to a mold, in particular to an angle steel opening and closing angle mold. Background technique [0002] Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle. It can be divided into equilateral angle steel and unequal angle steel. Angle steel can be composed of various stress components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, cranes, etc. Transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc. [0003] The angle between the two legs of the angle steel is 90°. According to the different installation positions in the iron tower structure, the angle between the two legs of the angle steel sometimes needs to be gr...

AI Technical Summary

Problems solved by technology

[0004] The existing angle steel opening and closing angle molds generally make different molds according to different angles. For example, the Chinese utility model patent "An Angle Steel Opening and Closing Angle Mold" (Notice No. CN 201436100 U) discloses a lower mold and a lower mold The formed mold can complete the opening and closing angle processing on one side of the angle steel through the cooperation of the top plate of the upper mold and the top plate of the lower mold. However, this top plate structure cannot be used for the opening and closing of angle steel at various angles. Different angles are used to replace the mold, which requires a certain amount of mold replacement and installation and debugging time
