[0024] See also Figures 2 to 5 The reinforcing steel cage stirrup winding device provided in this embodiment includes a bending machine 1, a bending member 2 and a spiral member 3.

[0025] The bending machine 1 is a commonly used device in the art. In this embodiment, it is preferably a GE40 bending machine 1 . A horizontally arranged turntable 11 is provided on the driving end of the bending machine 1 .

[0026] The bending member 2 is cylindrical and coaxially arranged on the turntable 11. A first positioning portion is arranged on the turntable 11, and a second positioning portion is arranged at the bottom of the bending member 2. The first positioning portion and the second positioning portion are arranged in a concave-convex manner to achieve the positioning of the bending member 2 and the turntable 11, so that when the turntable 11 rotates around its axis, the bending member 2 can be driven to rotate synchronously.

[0027] The top of the bending member 2 is provided with a fixing seat 4 and a bulletproof member 5, and a mounting hole is provided on the fixing seat 4. The first end of the bulletproof member 5 is rotatably connected in the mounting hole, and the second end of the bulletproof member 5 protrudes from the peripheral wall of the bending member 2, and the second end of the bulletproof member 5 can be turned up and down around its first end. The second end of the bulletproof member 5 is provided with a cross bar 51, and the cross bar 51 is vertically arranged with the bulletproof member 5. The rotation center of the bulletproof member 5 is eccentrically arranged with the center of the bending member 2. When the bulletproof member 5 is turned over to the first side of the mounting hole, the second end of the bulletproof member 5 protrudes from the outer peripheral wall of the bending member 2 to prevent the steel bar from rebounding; when the bulletproof member 5180° is turned over to the other side of the mounting hole, the second end of the bulletproof member 5 and the cross bar 51 do not protrude from the outside of the bending member 2, that is, the projections of the second end of the bulletproof member 5 and the cross bar 51 fall on the top wall of the bending member 2, which facilitates the stirrup 9 that has been wound to move upward and detach from the bending member 2.

[0028] The spiral member 3 is arranged on the outer wall of the bending member 2. The spiral member 3 is formed with a spiral portion for positioning the steel bar on the outer wall of the bending member 2. The spiral portion extends upward along the outer wall of the bending member 2 in a spiral. The spiral portion has a uniform pitch, so that after the steel bar is wound along the spiral portion, the pitch of the stirrup 9 is equal to the pitch of the spiral portion, which is conducive to controlling the stirrup 9 to have a uniform pitch. The terminal end of the spiral portion is arranged close to the bulletproof member 5. An entrance and exit 8 for the steel bar to pass through is arranged between the terminal end of the spiral portion and the second end of the bulletproof member 5. Preferably, the entrance and exit 8 is formed between the terminal end of the spiral portion and the cross bar 51, so that the entrance and exit 8 is arranged on the terminal end of the spiral portion for the steel bar to pass through. At this time, on the radial projection surface, the second end of the bulletproof member 5 exceeds the spiral portion, so that when the steel bar is cut, the steel bar is blocked by the bulletproof member 5 and will not rebound and injure people.

[0029] In order to control the width of the entrance and exit 8 , a support column 6 is further provided on the top of the bending piece 2 . The support column 6 is arranged on one side of the fixing seat 4 close to the terminal end of the spiral portion, so that the middle part of the bulletproof piece 5 is supported on the support column 6 .

[0030] In order to set stirrups 9 with different pitches according to actual needs, the spiral member 3 of the present embodiment is fixedly connected to the bending member 2, and the bending member 2 is detachably connected to the turntable 11. During actual operation, multiple spiral members 3 with different pitches can be set, and the spiral members 3 with different pitches are respectively fixedly connected to different bending members 2. The user can wind stirrups 9 with the required pitch by replacing the appropriate bending member 2.

[0031] In other embodiments, the bending member 2 is fixedly connected to the turntable 11, and the spiral member 3 is detachably connected to the bending member 2. In actual operation, a plurality of spiral members 3 with different pitches can be provided, and when necessary, the spiral members 3 on the bending member 2 can be replaced separately to wind stirrups 9 with appropriate pitches.

[0032] In order to facilitate the fixation of the steel bars so that the steel bars can be wound around the spiral portion, in one embodiment, a first fixing portion 12 is provided on the turntable 11, and the first fixing portion 12 is provided on the outside of the spiral portion. The first fixing portion 12 is provided close to the starting end of the spiral portion, and the first end of the steel bar is connected or adjacent to the first fixing portion 12. During the rotation of the bending member 2, the steel bar is manually wound around the spiral portion.

[0033] In another embodiment, a second fixing portion (not shown in the figure) is provided at the lower portion of the bending member 2, and a fixing groove for fixing the steel bar is formed between the second fixing portion and the starting end of the spiral portion. The first end of the steel bar is embedded in the fixing groove, and during the rotation of the bending member 2, the steel bar is manually wound around the spiral portion.

[0034] See also Figure 6 , and combined with Figure 1Since the bending machine 1 and the bending piece 2 both have a certain height, and the wound stirrups 9 need to be detached from the upper part of the bending piece 2, in order to facilitate workers to wind and remove the stirrups 9, this embodiment provides an operating platform 7 on one side of the bending machine 1, preferably a step, and the workers can stand on the step to perform the winding operation.

[0035] See also Figure 7 , and combined with Figure 4 The bending member 2 includes a top cover 21, a sleeve 22 and a plurality of straight steel bars 23. The plurality of straight steel bars 23 are evenly arranged along the inner circumferential wall of the sleeve 22. The straight steel bars 23 are welded and fixed to the inner circumferential wall of the sleeve 22. The top cover 21 is welded to the upper part of the sleeve 22.

[0036] In summary, the utility model provides a bending piece for bending a steel bar to form a spiral shape; a spiral piece is provided on the bending piece so that a spiral portion with a uniform pitch is formed on the bending piece. When the stirrup is wound, the steel bar is positioned on the spiral portion so that the pitch of the wound stirrup is equal to the pitch of the spiral portion, which is conducive to controlling the stirrup to have a uniform pitch; and a bulletproof piece is provided so that when the stirrup is wound and the steel bar needs to be cut, the stirrup is blocked by the bulletproof piece to prevent the steel bar from rebounding and injuring people.
