Description

Steel taking machine

Technical Field

The invention relates to the technical field of steel rolling auxiliary equipment, in particular to a steel taking machine.

Background

In a production workshop of a steel rolling mill, the movable beam on the feeding rack moves in a stepping mode, the steel billets are conveyed to the position close to the end of the static beam of the feeding rack, and the steel billets automatically slide onto a roller way along the inclined plane of the static beam by utilizing the gravity of the steel billets. However, because the top end of the static beam has a larger vertical distance with the roller way surface, the billet generates great impact on the roller way and the side baffle when sliding down on the roller way, and the service life of the equipment is greatly shortened.

The steel taking machine for moving the steel billet is generally adopted at present and comprises a lifting hydraulic cylinder and a translation hydraulic cylinder, wherein the lifting hydraulic cylinder controls the lifting beam to move up and down, the translation hydraulic cylinder controls the lifting beam to move horizontally, and the actions of taking and discharging are completed through the vertical and horizontal combined motion. Although the steel taking machine can achieve the purposes of taking materials from the static beam and discharging the materials onto the roller way, the action completion of the steel taking machine needs two hydraulic cylinders to be controlled together, and the steel taking machine has the advantages of multiple driving sources, complex structure, poor control precision and high comprehensive cost. In addition, the kinematic pair between the bottom plate of the lifting beam and the riding wheel is a high pair, and because the weight of the steel billet is large, the pressure on the bottom plate and the riding wheel is large, the abrasion is serious, the maintenance frequency is high, and the service life of the equipment is prolonged. The traditional steel taking machine needs at least two sets of material shifting mechanisms to complete two actions of shifting in and shifting out of steel billets, and has the advantages of complex structure, high equipment cost and lower working efficiency. Meanwhile, the traditional steel taking machine cannot adapt to steel billets of all sizes, and the steel taking machine needs to be replaced when the length of the steel billets exceeds the limit, so that the working efficiency of the steel taking machine is directly reduced.
