Abstract

A steel turning rack comprises a rack, a supporting arm and a roller way, wherein the rack is divided into two parts, the middle parts of the rack are fixedly connected through bolts, one end of the rack is fixedly arranged on the roller way, and the other end of the rack is provided with a stop block; one end of the supporting arm is fixedly installed on the workshop ground foundation, and the other end of the supporting arm is fixedly connected with the rack. The rack is of a net structure so as to facilitate the falling of the lifting hook; the rack is in a horizontal state when not in work. The number of the supporting arms is two, and the two supporting arms are respectively arranged at the central symmetrical positions of the rack. The invention has simple structure, stable operation and convenient maintenance, and can reduce the production cost; the operation is automatic or remote control operation, so that the safety factor is improved; the steel billet directly enters the roller way to be rolled for the next time after being overturned, so that the production efficiency is improved.

Description

Steel turnover rack

Technical Field

The invention belongs to the technical field of metallurgy, and particularly relates to a tilting rack.

Background

In the production process of rolling the billet, the billet needs to be turned over for the next rolling pass. The steel turnover equipment used in the prior art is a hydraulic steel turnover machine and a mechanical clamp type steel turnover machine, and has the problems of poor safety and reliability, low efficiency, difficult maintenance, difficult debugging and the like, so that the design and the research of a novel stable and reliable efficient steel turnover rack are an important way for improving the production efficiency of steel blank rolling.

The Chinese patent application CN104492817A discloses a waste removing rack with a steel turning function, which comprises a steel removing machine arm, a roller way, a cold blank rack movable beam and a cold blank rack static beam. The invention has the advantages of reducing the labor intensity of workers, improving the steel turnover efficiency and having high safety coefficient, still needs manual operation, and does not completely realize automation and intellectualization.

Disclosure of Invention

The invention aims to provide a tilting rack which is low in failure rate, small in maintenance amount, stable in operation and high in safety coefficient.

The technical scheme of the invention is as follows:

a steel turnover rack comprises a rack, a supporting arm and a roller way, wherein the rack is divided into two parts, and the middle parts of the rack are fixedly connected through bolts; one end of the rack is fixedly arranged on the roller way, and the other end of the rack is provided with a stop block; one end of the supporting arm is fixedly installed on the workshop ground foundation, and the other end of the supporting arm is fixedly connected with the rack.

The rack is of a net structure so as to facilitate falling of the lifting hook and heat dissipation of the rack; the rack is in a horizontal state when not in work. The hooks fall from the outermost end of the rack web.

The number of the supporting arms is two, and the two supporting arms are respectively arranged at the central symmetrical positions of the rack. The driving mode of the supporting arm is hydraulic cylinder driving. The number of times the billet needs to be turned is determined by the height of the billet when the billet is laid down.

The invention principle is as follows:

when the square steel billet needs to be turned over, the supporting arm is lifted, and the rack forms an inclined plane at the moment; the steel billet to be turned over is moved over by a lifting hook in a transverse mode and placed on the height of the inclined plane of the rack with the required turning times, the lifting hook descends, and the steel billet achieves the purpose of turning over due to the gravity of the steel billet; the steel billet is directly rolled on a roller way and is directly conveyed to the next rolling.

The invention has the beneficial effects that: the structure is simple, the operation is stable, the maintenance is convenient, and the production cost is further reduced; the operation is automatic or remote control operation, so that the safety factor is improved; the steel billet directly enters the roller way to be rolled for the next time after being overturned, so that the production efficiency is improved.

Fig. 2 is a schematic view of the operating principle and structure of a tilting table frame.

In the figure: 1-a rack, 2-a supporting arm, 3-a roller way, 4-a bolt, 5-a stop block and 6-a lifting hook.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in figure 1, the steel turning rack comprises a rack (1), a supporting arm (2) and a roller way (3), wherein the rack (1) is divided into two parts, the middle parts of the two parts are fixedly connected through a bolt (4), one end of the rack (1) is fixedly arranged on the roller way (3), and the other end of the rack is provided with a stop block (5); one end of the supporting arm (2) is fixedly arranged on the ground foundation of the workshop, and the other end of the supporting arm is fixedly connected with the rack (1).

The rack (1) is of a net structure so as to facilitate the falling of the lifting hook (6) and the heat dissipation of the rack (1); the bench (1) is in a horizontal state when not working. The lifting hook (6) falls down from the outermost end of the net structure of the rack (1).

The number of the supporting arms (2) is two, and the two supporting arms are respectively arranged at the central symmetrical position of the rack (1). The driving mode of the supporting arm (2) is hydraulic cylinder driving. The number of times the billet needs to be turned is determined by the height of the billet when the billet is laid down.

As shown in figure 2, when a square steel billet with the size of 150 mm × 150 mm × 1200 mm needs to be turned over, a supporting arm (2) is lifted, a rack (1) forms an inclined plane, the steel billet needing to be turned over is transversely moved by a lifting hook (6) and placed on the height of the inclined plane of the rack (1) with the required turning times, the lifting hook (6) is lowered, the steel billet achieves the purpose of turning over due to the self-generated gravity, and the steel billet is directly rolled onto a roller way (3) and is directly conveyed to the next rolling.
