Bar rolled steel finishing collecting system and collecting method thereof

Abstract

The invention relates to a bar rolled steel finishing collecting system and a collecting method thereof, and belongs to the technical field of small bar rolled steel finishing in the metallurgical industry. According to the technical scheme, the collecting method comprises the steps that a bar buffering device is arranged at the position, located on the upper part of a U-shaped collecting tank (26), in the U-shaped collecting tank (26), and a bar flushing device is arranged on one side of the U-shaped collecting tank (26); the bar buffering device comprises a left retaining finger (6), a right retaining finger (7) and a retaining finger driving air cylinder (9), and one end of the left retaining finger (6) and one end of the right retaining finger (7) are rotationally connected to the two corresponding side walls of the U-shaped collecting groove (26) correspondingly; and the bar flushing device comprises a flushing baffle (13), a guide rod (15) and a flushing baffle driving cylinder (16). The bar rolled steel finishing collecting system has the beneficial effects that bar fall is reduced, and the situation that in the bar collecting process, the bending degree is out of tolerance, bumping damage is caused, and the end parts of bars are uneven due to bar crossing and winding is avoided.

Description

technical field [0001] The invention relates to a bar rolling finishing collection system and a collecting method thereof, belonging to the technical field of small-sized bar rolling finishing in the metallurgical industry. Background technique [0002] With the continuous increase of domestic high-end special steel market demand, users have also put forward higher and higher requirements for product performance and internal quality. The steel rolling finishing collection area is an important production process of the bar rolling mill. After the bar rolling is completed and before the bar enters the vertical falling machine, the chain conveyor itself has a long conveying distance, and the bar is moving In the process, due to the length and curvature of the bars, the bars cannot be parallel before they are transported to the end of the chain conveyor and fall into the vertical steel drop machine, and the falling positions are relatively concentrated, resulting in crossover be...

AI Technical Summary

Problems solved by technology

[0005] (1) The drop is large, and the bars are not parallel due to impact and other reasons before and during the fall, that is, the bars are crossed and entangled. The smaller the diameter specification, the more obvious it is. If the bars are bundled and packaged, the entanglement will increase. The bending degree of the bar cannot guarantee the product quality, which affects the use of downstream high-end customers;

[0006] (2) Falling into the same position for a long time, the bundle shape is not good and uneven, and the falling position cannot be evenly divided into two positions on the cross section, which affects the improvement of packaging quality and the company's product image;

[0007] (3) The vertical drop is large. When the bars are in contact with each other and the bar and the supporting arm of the steel drop machine during the fall process, it is easy to produce bumps or scratches, which will affect the surface quality of the product. Quality requirements are often very high, otherwise it will have a greater impact on the quality and life of products processed by downstream customers;

[0008] (4) The vertical drop is large, which has a large impact on the equipment, especially when the specification is large, there is no buffer mechanism, which is likely to affect the life of the steel drop machine transmission mechanism and the supporting arm;

[0009] (5) Because the bars fall into the falling steel machine before and after they are prone to non-parallel, the ends of the bars are uneven, which affects the quality of bundling and packaging, and the safety during hoisting and transportation
