Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to a feeding device for an angle steel opening and closing angle device. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel bar with two sides perpendicular to each other at an angle. It is divided into equal-angle angle steel and unequal-angle angle steel. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

[0003] When processing the opening and closing angle of angle steel, a conveying device is required to stably convey the angle steel into the angle steel opening and closing angle. For example, the application document with the authorization announcement number CN209701749U discloses an automatic conveying table for angle steel, including a conveying frame arranged on the right side of an angle steel cutting table. One or more horizontal conveyors are arranged at intervals on the conveying frame. The horizontal conveyor includes a first fixing frame. On the first fixing frame, a second cylinder with an output shaft facing upward is provided. The output shaft of the second cylinder is connected to a "U"-shaped positioning frame. The opening of the positioning frame faces upward. Two spaced first rolling discs are hinged in the positioning frame through a first rotating shaft. A clamping opening for placing angle steel is formed between the two first rolling discs. And the rolling direction of the first rolling discs faces the angle steel cutting table. All the clamping openings are on the same plane. A slide bar is provided above and below the front side of the conveying frame. A push rod fixing frame placed on one side of the rightmost clamping opening is slidably connected in the two slide bars. A push rod is provided above the push rod fixing frame. A push block capable of pushing the angle steel on the clamping opening towards the angle steel cutting table is provided on the push rod.

[0004] Although the above patent realizes automated operation and improves work efficiency, it can only push and feed long-length angle steel and cannot push and feed short-length angle steel.
