The process flow of the scheme is as follows: a single reinforcing bar is tractioned by a winding machine and a corresponding rectangular mold to form a stirrup with a designed shape.

[0034] Further, a pulling plate track 3-3 for the pulling plates 3-2 to slide is formed on the base 3-1.

[0035] The working principle of the present utility model is as follows:

[0036] Step 1: Fabrication of the circular spiral stirrup 2

[0037] First step, convert the equal perimeter of the rectangular spiral stirrup 3 to be prefabricated and formed into the circular spiral stirrup 2 according to its size; adjust the Figure 1 retractable rotating frame 1-2 of the circular spiral stirrup 2 forming device to the corresponding diameter;

[0038] Second step, place the drum 1-4 wound with the steel bar raw material 1 on the drum track 1-3, draw one end of the steel bar raw material 1 into the stirrup winding frame 1-5 of the circular spiral stirrup 2 forming device, and fix one end of the steel bar raw material 1 on the retractable rotating frame 1-2; the rotation of the retractable rotating frame 1-2 can be realized by a driving device such as a rotating motor. The stirrup winding frame 1-5 moves along the winding frame track 1-6 of the mounting seat 1-1 under an external force, and the drum 1-4 moves along the drum track 1-3 under an external force. The movement of the stirrup winding frame 1-5 and the drum 1-4 can be realized by driving devices respectively connected with telescopic cylinders and other driving devices, and the forward speed of the stirrup winding frame 1-5 and the forward speed of the drum 1-4 are kept consistent, and the circular spiral stirrup 2 is formed by winding and processing, as Figure 4 shown; the stirrup winding frame 1-5 is provided to limit the winding position of the steel bar raw material 1 on the retractable rotating frame 1-2 each time, so as to prevent the phenomenon of dislocation of the wound circular spiral stirrup 2. As Figure 1 shown, when the stirrup winding frame 1-5 is moving, the steel bar raw material 1 will be continuously wound on the retractable rotating frame 1-2, and finally the circular spiral stirrup 2 is fabricated. Regarding the design principle of the forming device, it is a mature technical means in the technical field of the present invention. For example, a steel bar cage rolling machine can be used to fabricate the circular spiral stirrup. Since this part is not the main design concept of this application, it will not be elaborated herein.

[0039] Step 2: Conversion of the shape of the circular spiral stirrup

[0040] Put the circular spiral stirrup 2 into Figure 2On the shown conversion device, the design principle of the conversion is as follows: Rotate the rotating shaft 2-2. Since the shaping vertical rod 2-3 is connected to the rotating shaft 2-2 through an adjustment structure, the rotating shaft 2-2 will drive the shaping vertical rod 2-3 to rotate synchronously during the rotation process. As Figure 6 shown, the circular spiral stirrup 2 is extruded by the shaping vertical rod 2-3 to form a rectangular spiral stirrup 3. The specific implementation principle is as follows: Since a first hydraulic horizontal strut 2-5 is provided between the shaping vertical rod 2-3 and the fixed sleeve 2-4, and a second hydraulic horizontal strut 2-6 is provided between adjacent shaping vertical rods 2-3. The structural design principle of the first hydraulic horizontal strut 2-5 and the second hydraulic horizontal strut 2-6 is as follows: Since both the first hydraulic horizontal strut 2-5 and the second hydraulic horizontal strut 2-6 have adjustment functions, taking the first hydraulic horizontal strut 2-5 as an example, the cross-sectional dimensions can be calculated according to the rectangular spiral stirrup 3, and the first hydraulic horizontal strut 2-5 can be adjusted to a specified length. Thus, the positions of the four shaping vertical rods 2-3 can be determined, and the cross-sectional area enclosed by the four shaping vertical rods 2-3 can be determined. From this cross-sectional area, the cross-sectional dimensions of the rectangular spiral stirrup 3 can be deduced. With this design, the production of rectangular spiral stirrups 3 with various different cross-sectional dimensions can be applicable. Figure 7 The left side in is the initial state when the circular screw stirrup is placed into the conversion device. As the rotating shaft 2-2 rotates, it will drive the first hydraulic horizontal strut 2-5 and the shaping vertical rod 2-3 to rotate synchronously. Since the shaping vertical rod 2-3 is in direct contact with the circular screw stirrup, it has the effect of extruding the circular screw stirrup to cause deformation. In this application, 4 shaping vertical rods 2-3 are provided on the periphery of the rotating shaft 2-2, so the circular screw stirrup can be extruded and deformed into a rectangular screw stirrup. A second hydraulic horizontal strut 2-6 is provided between adjacent shaping vertical rods 2-3. The working principle of the second hydraulic horizontal strut 2-6 is the same as that of the first hydraulic horizontal strut 2-5. The second hydraulic horizontal strut 2-6 can strengthen the connection stability between the shaping vertical rods 2-3 and also adjust the distance between the shaping vertical rods 2-3. As Figure 7 shown, the left figure is the initial state when the circular spiral stirrup 2 is sleeved on the conversion device, and the right figure is that as the rotating shaft 2-2 rotates, it will drive the first hydraulic horizontal strut 2-5, the second hydraulic horizontal strut 2-6, and the shaping vertical rod 2-3 to rotate synchronously, and the shaping vertical rod 2-3 extrudes the circular spiral stirrup 2 to form a rectangular spiral stirrup 3. In the above embodiment, the rotating shaft 2-2 can be arranged on the chassis 2-1, and a rotating motor for driving the rotating shaft 2-2 to rotate is arranged on the chassis 2-1 to achieve the rotational motion.

[0041] Step Three: Tensile Principle of the Rectangular Spiral Stirrup 3

[0042] Place the rectangular spiral stirrup 3 made in Step 2 on the stretching device provided in this application, and stretch the rectangular spiral stirrup 3 to a specific length. The specific design principle is as follows: Connect the two ends of the rectangular spiral stirrup 3 to the pull plates 3-2 respectively, and pull the pull plates 3-2 to move the pull plates 3-2 along the pull plate track 3-3 on the base 3-1, so that the distance between the two pull plates 3-2 increases. At this time, the pull plates 3-2 will drive the rectangular spiral stirrup 3 to stretch along the length direction. During the stretching process, the operator can make the rectangular spiral stirrup 3 reach the designed spacing according to the requirements. The stretched rectangular spiral stirrup 3 is as Figure 3 shown. The movement of the pull plates 3-2 can be realized by a driving device such as manual or telescopic cylinder.

[0043] In the above technical solution, this application adjusts the distance between the shaping vertical rods and the rotating shafts through the adjusting structure, thereby adjusting the cross-sectional area jointly enclosed by the shaping vertical rods. Therefore, it can be adapted to the production of rectangular spiral stirrups 3 with a variety of different cross-sectional sizes, and can realize the batch production of rectangular spiral stirrups 3 with different cross-sectional sizes. The cross-section of the rectangular spiral stirrup 3 is neat and uniform, and it can better adapt to the adhesion with concrete during the pouring of rectangular cross-section members.

[0044] When this application produces the rectangular spiral stirrup 3, first use the circular spiral stirrup 2 forming device to make the circular spiral stirrup 2, and then convert it into the rectangular spiral stirrup 3 through the conversion device. During the whole process, the conversion device can also be adjusted to adapt to the conversion of rectangular spiral stirrups 3 with different cross-sectional sizes; the converted rectangular spiral steel bars can also be stretched through the stretching device according to the requirements of the use scenario to produce rectangular spiral steel bars with different spacing specifications.

[0045] In addition, the circular spiral stirrup 2 forming device of this application can also wind and produce circular spiral stirrups 2 with different diameters.
