Detailed Description
A steel bar guiding device for a steel bar straightener comprises a steel bar bracket and a steel bar pre-tensioning mechanism; the reinforcing steel bar bracket is used for placing reinforcing steel bars and preventing the disc reinforcing steel bars from swinging too much after being wound and rigidly separated when being output. The steel bar pre-tensioning mechanism can pre-tension the bent steel bars for the first time, so that the working load of a later straightening machine is reduced, and the straightening efficiency is improved.
As shown in fig. 1-2, the reinforcing steel bar bracket comprises a movable bracket body 1.1, and the movable bracket body 1.1 is composed of an upper U-shaped limiting rod 1.1.1 and a lower U-shaped limiting rod 1.1.2. The width between the upper U-shaped limiting rod 1.1.1 and the lower U-shaped limiting rod 1.1.2 is slightly larger than the diameter of the disc steel bar. And the walking wheel 1.1.3 is installed to lower U type gag lever post 1.1.2 bottom, conveniently removes from this. Last U type gag lever post 1.1.1, the welding has bracing 1.2 between the U type gag lever post 1.1.2 down, and bracing 1.2 leans out, makes things convenient for the disc reinforcing bar to support, and the welding has disc reinforcing bar vaulting pole 1.3 on one of them bracing 1.2, and disc reinforcing bar vaulting pole 1.3 stretches out the one end perk that makes progress.
When the reinforcing bar needs to be straightened, the reinforcing bar bracket can be pushed, so that the disc reinforcing bar support rod 1.3 penetrates through the disc reinforcing bar. And then shearing off the steel bars for binding the disc steel bars, enabling the scattered disc steel bars to lean against the inclined strut 1.2, and pressing the left side and the right side of the lower end of the disc steel bar on the lower U-shaped limiting rod 1.1.2. In the process of pulling the disc steel bar wire open, even if the steel bar rings are rigidly pulled open and separated due to winding, the steel bar rings gradually become small and are sleeved on the disc steel bar support rod 1.3, the steel bar rings swing up and down or left and right on the disc steel bar support rod 1.3, and the final swing is stopped and output due to the obstruction of the disc steel bar support rod 1.3, so that the later-stage deviation in the steel bar pre-tensioning mechanism due to the swing is avoided.
As shown in fig. 3-5, the reinforcing steel bar pre-tensioning mechanism includes a vertical alignment roller set 2.1 and a horizontal alignment roller set 2.2, and the first sheave block 2.3 and the second sheave block 2.4 of the vertical alignment roller set 2.1 are arranged in a vertically staggered manner to vertically extrude and align the reinforcing steel bar. And the first fluted roller group 2.3 and the second fluted roller group 2.4 of the horizontal straightening roller group 2.2 are arranged in a left-right staggered manner, so that the reinforcing steel bar is extruded and straightened in the left-right direction, and the straightening efficiency can be improved.
In order to carry out the centre gripping alignment to different reinforcing bars, install first sheave group 2.3 on first connecting plate 2.5, second sheave group 2.4 is installed on second connecting plate 2.6, all is fixed with slider 2.7 about first connecting plate 2.5, the second connecting plate 2.6, and slider 2.7 slides and sets up on slide rail 2.8, and slide rail 2.8 is fixed on support 2.9. Threaded sleeves 2.10 are fixed on the first connecting plate 2.5 and the second connecting plate 2.6, and the two threaded sleeves 2.10 are opposite in rotation direction and are in threaded connection through a screw rod 2.11. When rotating the handle on the screw rod 2.11, first connecting plate 2.5, second connecting plate 2.6 are close to relatively or keep away from, then adjust the interval of first grooved pulley group 2.3, second grooved pulley group 2.4, can press from both sides tightly and straighten the reinforcing bar of different specifications like this.
The adjacent distance between the grooved wheels in the first grooved wheel set 2.3 or the grooved wheels in the second grooved wheel set 2.4 is kept between 5mm and 8 mm. Maintaining a smaller spacing allows the device to be more compact overall while avoiding shifting of the rebar due to the swinging that exists when released.
