Description

Technical Field

[0001] The present application relates to the technical field of building material processing, and in particular to a steel bar straightening and protection device. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Plain round steel bars are actually small round bars and coils of ordinary low-carbon steel. Deformed steel bars are steel bars with ribs on the surface, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shapes of the transverse ribs are spiral, herringbone, and crescent. Most round steel bars are rolled into discs. When they are needed, they must be straightened before use, which requires the use of a steel bar straightening machine.

[0003] At present, a steel bar straightening machine is usually needed to straighten the steel bars. However, the traditional steel bar straightening machine is directly connected to the wire rod / screw. When the steel bars are put into the feeding port of the steel bar straightening machine, due to the stress of the steel bars, the part outside the steel bar straightening machine that has not yet entered may shake, causing the steel bars to be thrown out and cause harm to the workers, thus causing safety accidents. Therefore, further improvements can be made. Utility Model Content

[0007] By adopting the above technical scheme, during the steel bar straightening construction process, the steel bars to be straightened are successively passed through the feeding protection ring, the limit piece and the discharging protection tube in the protective bracket and then enter the steel bar straightening machine for processing, so that the steel bars are blocked by the protective cover part, thereby reducing the occurrence of safety accidents caused by the steel bars being thrown out due to shaking. At the same time, since the inner ring of the feeding protection ring is provided with a rotatable anti-collision inner ring, when the steel bar collides with the anti-collision inner ring during shaking, the rotatable anti-collision inner ring can rotate along the collision direction of the steel bar, thereby dispersing the impact force of the steel bar and extending the service life of the feeding protection ring.

[0023] 1. During the steel bar straightening construction process, the steel bar to be straightened passes through the feeding protection ring, the limiter and the discharging protection tube in the protection bracket in turn and then enters the steel bar straightening machine for processing, so that the steel bar is blocked by the protective cover, which reduces the safety accidents caused by the steel bar being thrown out due to shaking. At the same time, since the inner ring of the feeding protection ring is provided with a rotatable anti-collision inner ring, when the steel bar collides with the anti-collision inner ring during the shaking process, the rotatable anti-collision inner ring can rotate along the collision direction of the steel bar, thereby dispersing the impact force of the steel bar and extending the service life of the feeding protection ring;

[0024] 2. When the steel bar entering the feeding protection ring is shaken by the steel bar straightening machine and hits the feeding protection ring, the anti-collision inner ring located on the inner circumference of the feeding protection ring is connected with the sliding groove and the slider between the feeding protection ring, so that the anti-collision inner ring will contact the steel bar first.

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The embodiment of the present application discloses a steel bar straightening protection device.

[0032] Reference Figure 1 , 2 A steel bar straightening protection device comprises a rectangular protection bracket 1, wherein a protection cover 2 is formed along the length direction of the protection bracket 1 to prevent the steel bar from being thrown out due to shaking, wherein:

[0033] The protection bracket 1 includes a front frame 11, a rear frame 12 and a connecting longitudinal rib 13. The front frame 11 is arranged vertically to the ground, and the rear frame 12 is also arranged vertically to the ground.

[0034] The protective cover 2 includes a feeding protective ring 21, a limiting member 22 and a discharging protective cylinder 23. The feeding protective ring 21 is arranged in the front frame 11, and the feeding protective ring 21 is fixed against the four sides of the inner side of the front frame 11; the discharging protective cylinder 23 is arranged in the rear frame 12, and a fixing seat 4 is arranged on the inner side of the rear frame 12, and the discharging protective cylinder 23 is arranged on the fixing seat 4; the two ends of the limiting member 22 are respectively connected to the feeding protective ring 21 and the discharging protective cylinder 23 in a surrounding manner, the diameter of the feeding protective ring 21 is larger than the diameter of the discharging protective cylinder 23, and the inner ring of the feeding protective ring 21 is provided with a rotatable anti-collision inner ring 3.

[0035] During the steel bar straightening construction process, the steel bars to be straightened are successively passed through the feeding protection ring 21, the limit piece 22 and the discharge protection tube 23 in the protection bracket 1 and then enter the steel bar straightening machine for processing, so that the steel bars are blocked by the protective cover 2 to reduce the safety accidents caused by the steel bars being thrown out due to shaking. At the same time, since the inner ring of the feeding protection ring 21 is provided with a rotatable anti-collision inner ring 3, when the steel bars collide with the anti-collision inner ring 3 during shaking, the rotatable anti-collision inner ring 3 can rotate along the collision direction of the steel bars, thereby dispersing the impact force of the steel bars and extending the service life of the feeding protection ring 21.

The slider 6 can be slidably arranged in the slide groove 5, and an anti-collision rubber tube 7 is sleeved on the inner side of the anti-collision inner ring 3 along its circumference.

[0037] In actual use, when the steel bar entering the feeding protection ring 21 is shaken by the steel bar straightening machine and hits the feeding protection ring 21, the anti-collision inner ring 3 located on the inner circumference of the feeding protection ring 21 is connected with the slide groove 5 and the slider 6 between the feeding protection ring, so that the anti-collision inner ring 3 will contact the steel bar first. When hit by the steel bar, the anti-collision inner ring 3 rotates, thereby sharing the impact force and protecting the feeding protection ring 21. At the same time, the anti-collision rubber tube 7 set on the inner circumference of the anti-collision inner ring 3 helps to reduce the damage to the anti-collision inner ring 3 caused by the steel bar during the straightening process, and increase the service life of the anti-collision inner ring 3.
