DETAILED DESCRIPTION

[0028] The embodiments of the present application will be further described in conjunction with the drawings and examples. The detailed description and drawings of the following examples are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, i.e., the present application is not limited to the described examples.

[0029] In order to better understand the present application, the present application will be further described in conjunction with the drawings and embodiments as follows:

[0030] Referring to Figure 1 and Figure 2 The present application provides a reinforcing hoop forming device, which comprises a driving mechanism 1 and a winding bar assembly 2, the winding bar assembly 2 is arranged on the driving mechanism 1, and the driving mechanism 1 is used to drive the winding bar assembly 2 to rotate.

[0031] In the present embodiment, the driving mechanism 1 is the power source of the reinforcing hoop forming device, which is responsible for providing rotary motion to drive the winding bar assembly 2 to complete the bending forming process of the reinforcing bar. The driving mechanism 1 can adopt a power source such as a motor, a hydraulic motor or a pneumatic motor. The driving mechanism 1 is equipped with a speed reducer and a transmission system to ensure that the output rotation speed and torque can meet the needs of the winding bar assembly 2. It should be noted that the driving mechanism 1 in the present embodiment is prior art, and the design parameters and specific models of the driving mechanism 1 can be obtained from the prior art according to the actual production needs, therefore, the present embodiment does not make too much description on the driving mechanism 1.

[0032] In the present embodiment, the winding bar assembly 2 is the part that directly contacts and bends the reinforcing bar, which comprises a ring-shaped support 21 and a plurality of positioning rods 22, the ring-shaped support 21 is a closed circular structure, and the positioning rods 22 are uniformly distributed in the inner circle of the ring-shaped support 21, which plays a role in fixing and guiding the reinforcing bar.

[0033] Specifically, the positioning rods 22 play a role in guiding the reinforcing bar to bend along the set trajectory, in some embodiments, in order to improve the forming effect, the surface of the positioning rods 22 is usually specially treated, such as chrome plating or spraying wear-resistant coating, to reduce the friction and prolong the service life.

[0034] In order to further explain and illustrate, the present embodiment also provides a bending forming process of the reinforcing cage, which is as follows:

[0035] When the driving mechanism 1 starts, the winding assembly 2 begins to rotate at a preset speed. At this time, one end of the reinforcing bar is fixed outside the winding assembly 2. As the winding assembly 2 rotates, the reinforcing bar is gradually pulled into the annular support 21 and is bent along the guide of the positioning rod 22. Due to the equidistant arrangement of the positioning rods 22, the reinforcing bar will form a fixed bending angle at each positioning rod 22, and finally form a complete circular or spiral reinforcing hoop.

[0036] In another embodiment, in order to ensure that the reinforcing bar can smoothly enter the winding assembly 2 and complete the bending, a reinforcing bar feeding mechanism is provided. The reinforcing bar feeding mechanism can automatically adjust the feeding speed according to the length and diameter of the reinforcing bar, to ensure that the reinforcing bar does not jam or break during the bending process. The reinforcing bar feeding mechanism can also be controlled synchronously with the driving mechanism 1 to realize continuous production of reinforcing hoops. The reinforcing bar feeding mechanism can use existing reinforcing bar feeding mechanisms, and the present application will not be described in detail.

[0037] In an embodiment, the driving mechanism 1 includes a main box body 11 and a rotating disc 12 arranged at the upper end of the main box body 11. The rotating disc 12 is provided with a plurality of fixed columns 13 arranged in a linear manner.

The power source includes but is not limited to an electric motor, a hydraulic motor or a pneumatic motor, and the specific selection depends on the power requirement and application scenario of the equipment. For example, in large reinforcing cage processing, a high-power electric motor is needed to drive the rotating disc 12.

[0039] The rotating disc 12 is connected with the winding assembly 2. The upper end of the rotating disc 12 is provided with a plurality of fixed columns 13 arranged in a linear manner. The fixed columns 13 provide fixed fulcrums for the winding assembly 2, so that the winding assembly 2 can rotate under the driving of the rotating disc 12.

[0040] Specifically, the annular support 21 is provided with a first limiting piece 23 extending along the Y-axis direction and a second limiting piece 24 extending along the X-axis direction. The first limiting piece 23 is provided with two, and the second limiting piece 24 is provided with a plurality of. The plurality of second limiting pieces 24 are arranged equidistantly along the Y-axis direction and are fixedly installed on the two first limiting pieces 23.

[0042] The first limiting member 23 and the second limiting member 24 on the annular support 21 not only play a role of cooperating with the fixing column 13 to fix the fixing column 13, but also enhance the structural firmness of the muscle winding assembly 2.

[0043] Referring to Figure 2 As shown in the figure, in the orthographic projection direction of the muscle winding assembly 2, the limiting space formed by the two adjacent second limiting members 24 and the two first limiting members 23 is a square, and the diameter of the fixing column 13 is equal to the width of the square. Through the design that the limiting space is a square and the diameter of the fixing column 13 is equal to the width of the square, it can be ensured that the fixing column 13 will neither be loose due to excessive gap in the limiting space nor be difficult to install due to being too tight, and the muscle winding assembly 2 can be provided with a stable fulcrum to ensure that it can rotate smoothly under the driving of the rotating disc 12 and avoid shaking.

[0044] The annular support 21 is provided with a plurality of first reinforcing members 25 and a plurality of second reinforcing members 26.

One end of the plurality of second reinforcing members 26 converges at the middle of another first limiting member 23 and is fixedly connected with the middle of the first limiting member 23, and the other end of the plurality of second reinforcing members 26 is fixedly connected with the annular support 21. Among them, the included angle between any two adjacent first reinforcing members 25 is 30°, and the included angle between any two adjacent second reinforcing members 26 is 30°.

When the muscle winding assembly 2 is subjected to external impact during operation, the plurality of first reinforcing members 25 and the plurality of second reinforcing members 26 can play a supporting role to prevent the annular support 21 from deforming or being damaged.

[0046] In some embodiments, the muscle winding assembly 2 further comprises a mounting member 27, one end of the mounting member 27 is fixedly connected with one of the two first limiting members 23, the other end of the mounting member 27 is fixedly connected with the other of the two first limiting members 23, the mounting member 27 is located outside the annular support 21, and there is a mounting gap between the mounting member 27 and the annular support 21 for the steel bars to pass through. This design facilitates the fixing of the steel bars.

[0047] In order to prevent the round bar assembly 2 from shaking, a supporting member 14 is arranged on the rotating disc 12 and located between the rotating disc 12 and the round bar assembly 2.

[0048] In order to further strengthen the structural firmness of the round bar assembly 2, the round bar assembly 2 further comprises a pentagonal reinforcing member 28, and the plurality of first reinforcing members 25, the plurality of second reinforcing members 26 and the two first limiting members 23 are respectively welded and fixed with the reinforcing member 28.
