Description

Technical Field

[0001] The utility model belongs to the technical field of construction tools, in particular to a steel bar straightening and protection device. Background Art

[0002] A large amount of coiled steel bars are needed in the construction process of the foundation and main body of the building project. The coiled steel bars need to be straightened by a straightening machine before use. During the straightening process of the coiled steel bars, due to the relatively fast processing speed, the coiled steel bars rotate and enter the straightening machine, which can easily cause personal injury. Before the coiled steel bars enter the straightening machine, the coiled steel bars and the inlet of the straightening machine generate a large friction due to the action of the swinging inertia force, which can easily cause wear to the coiled steel bars and the inlet of the straightening machine. Utility Model Content

[0003] The purpose of the present invention is to provide a steel bar straightening protection device to solve the problems raised by the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar straightening protection device, comprising a protective cover and a support seat fixedly arranged below the protective cover, the protective cover is a trumpet-shaped shell with a large opening at one end and a small opening at the other end, a fixing ring is fixedly connected to one end of the small opening on the protective cover, a bearing is fixedly connected to the inside of the fixing ring, the outer ring of the bearing is fixedly connected to the inner side wall of the fixing ring, a plurality of groups of springs are fixedly connected to the inner side wall of the inner ring of the bearing along the circumference of the inner ring of the bearing, and the ends of the plurality of groups of springs are fixedly connected to a limiting sleeve, the limiting sleeve is a hollow shell with openings at both ends, and the opening direction of the limiting sleeve is the same as the opening direction of the protective cover.

[0005] Furthermore, a flange is fixedly connected to the fixing ring, and the fixing ring is fixedly connected to the opening of the straightening machine through the flange.

[0006] The fixing ring is connected to the inlet of the straightening machine through a flange to ensure that the axis of the coiled steel bar is aligned with the inlet of the straightening machine, thereby reducing the wear of the coiled steel bar and the inlet of the straightening machine.

[0007] Furthermore, the limiting sleeve is trumpet-shaped, and the directions of the openings at both ends of the limiting sleeve are the same as those of the protective cover.

[0008] The coiled steel bar is gradually gathered in the limiting sleeve through the trumpet-shaped limiting sleeve, thereby further reducing the swing amplitude of the coiled steel bar.

[0009] Furthermore, multiple groups of bearings and springs are arranged in the horizontal direction inside the fixing ring.

[0010] The buffering effect of the limit sleeve on the coiled steel bar is improved by multiple sets of bearings and springs.

[0011] Furthermore, a height-adjustable foot support is fixedly connected to the bottom of the support base.

[0012] By raising the height of the foot support adjustment device, it is convenient to align and connect the fixing ring with the inlet of the straightening machine.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a fixing ring and a bearing in the fixing ring, and the inner ring of the bearing is connected to a limiting sleeve by a spring. When the coiled steel bar is straightened, the coiled steel bar is first passed through the protective cover and the limiting sleeve, and then enters the straightening machine. When the coiled steel bar swings greatly, the protective cover can prevent the coiled steel bar from swinging and injuring people. The limiting sleeve can buffer the swinging inertia force of the coiled steel bar when entering the straightening machine through the spring, avoiding wear caused by friction between the coiled steel bar and the inlet of the straightening machine, and when the coiled steel bar swings and rotates in the limiting sleeve, the limiting sleeve can rotate synchronously with the inner ring of the bearing, thereby reducing the wear of the coiled steel bar in the limiting sleeve.
