[0023] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not to limit the scope of the utility model.

[0024] As described in the background, the existing simple stirrup processing device cannot be used for force main bars with large size difference when bending the stirrup based on its fixed bending part, so its adaptability is low, and it directly acts on the outer surface of the force main bar, and when the stirrup bending work is carried out, the hard friction between the circular arc member and the force main bar will increase the working intensity of the user, therefore, the embodiment provides a simple and detachable artificial processing steel bar work device, which can quickly bend the stirrup and facilitate replacement of the bending part to adapt to the stirrup bending work on the force main bars with large size difference, and can reduce the friction between the bending part and the force main bar, and reduce the working intensity of the user.

[0025] Referring to Figure 1 - Figure 5 The embodiment provides a simple and detachable artificial processing steel bar work device, which comprises a main body rod 1, and a bending head 2 is detachably installed at one end of the main body rod 1 through threads.

[0026] For details Figure 1 and Figure 2 Here, a threaded hole is formed at one end of the main body rod 1, and a matching threaded rod is integrally cast on the bending head 2, so that the threaded rod is rotated into the threaded hole, thereby realizing the connection of the main body rod 1 and the bending head 2, and the reverse rotation is only needed when disassembling.

[0027] Referring to Figure 2 , wherein Figure 2 The middle small groove part on the bending head 2 is the bending force part of the stirrup.

[0028] The bending head 2 is rotatably connected with a plurality of roller groups 3 for reducing friction, and the outer surface of the main body rod 1 is sleeved with a slidable limiting frame 4, and the limiting frame 4 is used to limit the rotation between the bending head 2 and the main body rod 1.

[0029] The specific working process of the bending head 2 is that the bending head 2 is sleeved on the stress main reinforcement, the stirrup is arranged perpendicularly with the stress main reinforcement, the stirrup is arranged in the small groove on the bending head 2, and the stress main reinforcement is bent by being extruded by the small groove on the bending head 2 when the bending head 2 is rotated along the central axis of the stress main reinforcement and the bending head 2.

[0030] At this time, the friction force between the inner wall of the bending head 2 and the stress main reinforcement caused by rotation can be reduced by the roller group 3, so that the rotation of the bending head 2 is more labor-saving.

[0031] The outer surface of the bending head 2 is provided with a gear slot 5, one end of the limiting frame 4 is fixedly connected with gear teeth 6 matched with the gear slot 5, and the gear slot 5 and the gear teeth 6 are engaged.

[0032] Based on the threaded connection between the bending head 2 and the main rod 1, under normal circumstances, one end of the main rod 1 is in contact with the threaded rod base on the bending head 2, if the bending head 2 is rotated, one end of the main rod 1 is separated from the threaded rod base on the bending head 2, the main stress between the bending head 2 and the main rod 1 will act on the threaded rod, which is easy to cause the threaded rod on the bending head 2 to break, the limiting frame 4 can limit the rotation of the bending head 2 on the main rod 1 through the gear slot 5 and the gear teeth 6, so as to avoid the bending head 2 from falling off or the threaded rod from breaking.

[0033] The limiting frame 4 is provided with a strip-shaped protrusion, and the strip-shaped protrusion on the limiting frame 4 slides in the strip-shaped groove on the main rod 1.

[0034] The strip-shaped groove can limit the rotation of the limiting frame 4 to avoid the rotation of the limiting frame 4 on the main rod 1.

[0035] At the same time, the limiting frame 4 can strengthen the connection strength between the main rod 1 and the bending head 2, so that the main rod 1 has more stress points when driving the bending head 2 to rotate.

[0036] One end of the limiting frame 4 is fixedly connected with a tension spring 7, and the other end of the tension spring 7 is fixedly connected to the outer surface of the main rod 1.

[0037] By arranging the tension spring 7, the limiting frame 4 can always tend to act on the bending head 2, and the bending head 2 and the limiting frame 4 can be separated when the bending head 2 needs to be disassembled.

[0038] The other end of the limiting frame 4 is rotatably connected with a driving ring 8 sleeved on the outer surface of the main rod 1 and slidable, and the outer surface of the driving ring 8 is provided with anti-skid stripes.

[0039] The inside of the driving ring 8 is provided with a strip-shaped protrusion, and the strip-shaped protrusion on the driving ring 8 is slidingly connected in the special-shaped groove on the main rod 1.

[0040] By setting the drive ring 8, the limiting frame 4 can be pulled to move a distance and the bending head 2 and the limiting frame 4 can be kept separated, which makes it easy to replace the bending head 2.

[0041] The irregular groove can limit the drive ring 8 after it slides and rotates, thereby maintaining the separation between the bending head 2 and the limiting frame 4.

[0042] A rubber handle 9 is fitted on the outer surface of the main rod 1, and anti-slip stripes are provided on the outer surface of the rubber handle 9.

[0043] By setting a rubber handle 9, the friction force when the user holds the main rod 1 can be increased, preventing the device from falling out of the user's hand and improving the device's practicality.

[0044] It should be noted that the sharp edges of the bending head 2 need to be blunted to prevent them from scratching workers or other equipment.

[0045] Working principle: When it is necessary to bend the stirrup, the bending head 2 is placed on the main reinforcing bar, and the stirrup is set perpendicular to the main reinforcing bar. The stirrup is placed inside the small groove on the bending head 2. When the bending head 2 is rotated along the central axis of the main reinforcing bar and the bending head 2, the main reinforcing bar will be bent by the pressure of the small groove on the bending head 2.

[0046] When the bending head 2 needs to be replaced, firstly, the limiting frame 4 is slid on the main body rod 1 by pulling the drive ring 8. At this time, the limiting frame 4 is separated from the bending head 2, and the groove 5 and teeth 6 are no longer engaged. When the drive ring 8 is pulled to the end of the stroke, the drive ring 8 is rotated slightly. At this time, the drive ring 8 cannot be reset due to the restriction between the strip-shaped protrusion and the irregular groove inside the drive ring 8. At this time, the bending head 2 is rotated down and a suitable bending head 2 is replaced. Then, the drive ring 8 is rotated in the opposite direction to reset. After the drive ring 8 is rotated to a sliding state, the tension spring 7 will drive the limiting frame 4 to move in the opposite direction and contact the bending head 2. The groove 5 and teeth 6 re-engage, completing the replacement of the bending head 2.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
