Unwinding device for hot-dip galvanized steel bars

Abstract

This application relates to the field of US solid cage processing, in particular to an unwinding device for hot-dip galvanized steel bars, including a base, a main shaft, a disk and a plurality of limit rods. In the same chute, the lower end of the limit rod is slidably embedded in the corresponding chute; the disc is provided with a first drive mechanism that drives multiple limit rods to expand outward or gather inward at the same time; the limit rod automatically There are a plurality of installation grooves distributed from top to bottom, and the installation groove is embedded with a pressing block and the first elastic part that pushes the part of the pressing block out of the installation groove; the disc is also equipped with a driving limit when the limit rod touches the steel coil. The second drive mechanism for the downward movement of the position bar. This scheme can not only adapt to steel bar coils with different inner ring diameters by changing the size of the circle surrounded by multiple limit rods, but also constrain the position of steel bar coils in the horizontal and vertical directions at the same time, greatly reducing the The probability of shaking of the steel bar roll during unwinding effectively ensures the normal unwinding of the steel bar roll.

Description

technical field [0001] The present application relates to the field of Meigu cage processing, in particular to an unwinding device for hot-dip galvanized steel bars. Background technique [0002] Hot-dip galvanized steel bars are characterized by strong hardness, wear resistance, and high bonding strength with the base metal. The mesh in the Meigu cage is often spot-welded by multiple criss-cross hot-dip galvanized steel bars. [0003] Coiled hot-dip galvanized steel bars need to be uncoiled, straightened and cut before spot welding. Such as Figure 4 , shown in the figure is an unwinding device, including a base 1, a main shaft 2 erected on the base 1, a disc 3 fixedly sleeved on the side wall of the main shaft 2 for supporting steel bar rolls, and a disc 3 erected on the disc 3, a plurality of limit rods 4 for limiting the slippage of steel bar coils. When the straightener straightened the reinforcing bar, the reinforcing bar on the disc 3 would be pulled out. [0004]...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned unwinding device has a simple structure, since the positions of the limit rods are fixed, it means that multiple limit rods can only limit the steel coils with a certain inner diameter. When the inner ring of the steel coil is equipped, the steel coil is easy to shake during the unwinding process, which affects the normal unwinding of the steel coil
