[0002] The hoop bending machine is a processing tool for steel bar operations. Its purpose is to process the steel bar into a specified angle and model. The hoop bending machine is generally divided into semi-automatic hoop bending machine and fully automatic hoop bending machine. Among them, the fully automatic CNC steel bar hoop bending machine can automatically complete the straightening, sizing, bending and cutting of steel bars. It has a very comprehensive processing capability and can process more and more complex shapes.

[0003] At present, the straightening method of the steel bar bending machine on the market is to adjust the straightness of the steel bar by manually adjusting the downward pressure of each straightening wheel. When replacing steel bars of different sizes, or when the diameter of the steel bar itself changes, especially when the straightness of two steel bars is inconsistent, the relative position of the individual adjustable wheels needs to be readjusted. The adjustment range mostly depends on the actual experience of the operator. If the operator is inexperienced, it will cause low efficiency of equipment use and affect product quality.

[0022] Figures 1 to 3 This is a schematic diagram of the structure of the fully automatic individually adjustable wheel mechanism shown in some embodiments of the present application. Figures 1 to 3 The fully automatic individually adjustable wheel mechanism involved in this application is introduced. It should be noted that: Figures 1 to 3 This is only an example, and the specific shape and structure of the fully automatic individually adjustable wheel mechanism are not limited.

[0023] See also Figures 1 to 3 In this embodiment, the fully automatic individually adjustable wheel 5 mechanism includes a straightening wheel 2, an adjustable wheel assembly and a driving mechanism; the straightening wheel 2 is rotatably fixed on the straightening wheel plate 1, the adjustable wheel assembly includes an adjustable wheel plate 4 and two rotatable individually adjustable wheels 5 installed on both sides of the adjustable wheel plate 4, and the driving mechanism is used to drive the adjustable wheel plate 4 to swing.

[0024] In this embodiment, the straightening wheel 2 and the adjustable wheel assembly form an adjustable straightening wheel group. When the steel bar 14 passes through the straightening wheel group formed by the straightening wheel 2 and the adjustable wheel assembly, the steel bar 14 can be straightened under the action of the straightening wheel group. At the same time, the driving mechanism can adjust the swing angle of the adjustable wheel plate 4 according to the actual production conditions, so as to adjust the spacing between the separate adjustable wheels 5 on both sides of the adjustable wheel plate 4 and the straightening wheel 2, and complete the adjustment of the straightness of the steel bar 14 when the steel bar 14 is straightened.

[0025] See also Figure 4 When the adjustable wheel plate 4 swings counterclockwise, the steel bar 14 can be bent upward. Figure 5 Correspondingly, when the adjustable wheel plate 4 swings clockwise, the steel bar 14 can be bent downward. In this way, the straightness of the steel bar 14 can be automatically adjusted according to the actual production conditions. Thereby, the straightening accuracy of the steel bar 14 is improved, and the product quality is improved.

[0026] In some embodiments, the driving mechanism includes a rotating shaft 12, a fine-tuning transmission joint 9 and a fine-tuning transmission shaft 10; one end of the rotating shaft 12 is fixedly connected to the adjustable wheel plate 4, and the other end thereof passes through the straightening wheel plate 1 and is fixedly connected to the rotating arm 8; the fine-tuning transmission joint 9 is hingedly connected to the strip hole of the rotating arm 8 through a pin shaft 15; one end of the fine-tuning transmission shaft 10 is threadedly connected to the fine-tuning transmission joint 9, and the other end thereof is connected to the motor 3 fixed on the straightening wheel plate 1 and can be driven to rotate by the motor 3.

[0027] In this embodiment, the driving mechanism has a driving principle that the fine-tuning transmission shaft 10 is driven to rotate by the motor 3, and because the fine-tuning transmission shaft 10 is threadedly connected to the fine-tuning transmission joint 9, and because the fine-tuning transmission joint 9 is hingedly connected to the rotating arm 8. When the fine-tuning transmission shaft 10 rotates, since the fine-tuning transmission joint 9 is not rotatable, the fine-tuning transmission joint 9 threadedly connected to the fine-tuning transmission shaft 10 will move in the horizontal direction of the fine-tuning transmission shaft 10 under the action of the thread, thereby driving the rotating arm 8 to rotate, and finally the rotating arm 8 drives the adjustable wheel plate 4 to swing through the rotating shaft 12, so as to achieve the purpose of automatically adjusting the straightness of the steel bar 14. Among them, the forward and reverse rotation direction of the motor 3 will determine the swing direction of the adjustable wheel plate 4. In order to ensure that the fine-tuning transmission joint 9 can always keep level with the fine-tuning transmission shaft 10, the connection hole at the hinge of the rotating arm 8 and the fine-tuning transmission joint 9 is a strip hole, and the strip hole can adjust the position of the fine-tuning transmission joint 9 when the rotating arm 8 swings so that it keeps level with the fine-tuning transmission shaft 10.

[0028] In addition, in order to be suitable for a CNC hoop bending machine with a double-row straightening mechanism, two sets of side-by-side adjustable wheel assemblies can be provided, and the rotating shaft 12 of the driving mechanism of one of the adjustable wheel assemblies close to the straightening wheel plate 1 is made into a sleeve 13, which is sleeved on the rotating shaft 12 of the driving mechanism of the other set of adjustable wheel assemblies. The length of the sleeve 13 after extending out of the straightening wheel plate 1 is smaller than the rotating shaft 12, and both are fixedly mounted on the rotating arm 8, so that the two side-by-side adjustable wheel assemblies can be driven by the two sets of driving mechanisms to adjust the straightening degree of the two steel bars 14 without interfering with each other.

[0029] Preferably, the motor 3 is fixed on the straightening wheel plate 1 through the motor mounting plate 11 , so that the motor 3 can be conveniently and firmly mounted on the straightening wheel plate 1 .

[0030] In some embodiments, a linear displacement sensor 7 is also provided on the straightening wheel plate 1 , one end of the linear displacement sensor 7 is hingedly connected to a sensor mounting shaft 6 fixed on the straightening wheel plate 1 , and the other end thereof is hingedly connected to a rotating arm 8 .

[0031] The linear displacement sensor 7 can collect the rotation information of the rotating arm 8 and feed it back to the control system of the driving mechanism, so as to accurately determine whether the rotating arm 8 is rotated in place. Specifically, the linear displacement sensor 7 can adopt KPC, KPM fisheye articulated displacement sensors, and fisheye joints are provided at both ends of such linear displacement sensors 7, which can facilitate the connection and installation between the linear displacement sensor 7 and the sensor installation shaft 6 and the rotating arm 8.

[0032] In some embodiments, both the straightening wheel 2 and the single adjustable wheel 5 are provided with an annular groove. The annular groove plays a certain clamping role on the steel bar 14, thereby preventing the steel bar 14 from deviating and separating from the straightening wheel 2 and the single adjustable wheel 5, and also ensuring that the steel bar 14 can fit with the straightening wheel 2 and the single adjustable wheel 5, thereby ensuring the accuracy of straightening.

[0033] The above is an embodiment of the present invention. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the verification process of the invention, and are not intended to limit the patent protection scope of the present invention. The patent protection scope of the present invention shall still be subject to its claims, and any equivalent structural changes made by using the contents of the description and drawings of the present invention shall be included in the protection scope of the present invention.
