Method used

A stirrup forming device is designed, including a frame, a forming core mold and a pressing mechanism. The pressing mechanism includes a side pressing assembly and a bottom pressing assembly through which the bottom surface and both side edges of the U-shaped stirrup are pressed against the forming core die, thereby maintaining the shape of the stirrup during bending.

Benefits of technology

By setting up a pressing mechanism, the U-shaped stirrups are always close to the forming core mold when bending, so that the parts that do not need to be bent are not easily deformed, which significantly improves the forming effect of the stirrups.

[0025] like Figures 1 to 3 As shown, the stirrup forming device of this embodiment includes a frame 1, on which is provided a forming core mold 2 and a forming mechanism 3 for bending the U-shaped stirrup into annular stirrups. The frame 1 is also provided with a clamping mechanism 4 for pressing the bottom and side of the U-shaped stirrup against the forming core mold 2.

[0026] The stirrup forming device of this embodiment, when forming, first, the pressing mechanism presses the bottom surface and both sides of the U-shaped stirrup onto the forming core mold 2, and then the forming mechanism 3 cooperates with the forming core mold 2 to bend the U-shaped stirrup into an annular stirrup, completing the forming of the stirrup. The stirrup forming device of this embodiment has a simple structure. By setting the pressing mechanism 4, the U-shaped stirrup is always close to the forming core mold 2 during bending, so that the part of the U-shaped stirrup that does not need to be bent is not easily deformed, and the forming effect is good.

[0027] Furthermore, in this embodiment, the clamping mechanism 4 includes side clamping components 41 located on both sides of the forming core mold 2. The side clamping components 41 are used to clamp the two sides of the U-shaped stirrup onto the forming core mold 2, so that the two sides of the U-shaped stirrup are not easily deformed; at the same time, because the two sides of the U-shaped stirrup are pressed against the forming core mold 2, it is helpful to prevent the force during molding from being transmitted downward, so that the bottom of the U-shaped stirrup is not easily deformed, further ensuring the molding effect.

[0028] Furthermore, in this embodiment, the side clamping assembly 41 includes a lateral drive 411 and a side clamping member 412 for clamping the side edge of the U-shaped stirrup onto the forming core mold 2, and the lateral drive 411 is connected to the side clamping member 412. The lateral drive 411 drives the side clamping member 412 to move in the lateral direction, thereby clamping or loosening the side edge of the U-shaped stirrup and the forming core mold 2, and the structure is simple and reasonable. Among them, the lateral drive 411 can be, for example, a cylinder, an oil cylinder, or an electric push rod, etc., which will not be repeated.

[0029] Furthermore, in this embodiment, the side clamping member 412 is a clamping cylinder. The arc surface of the clamping cylinder can effectively clamp the U-shaped stirrups to ensure the clamping effect, and is also helpful to prevent the surface of the U-shaped stirrups from being damaged.

[0030] Furthermore, in this embodiment, the clamping mechanism 4 also includes a bottom clamping assembly 42 located below the forming core mold 2. The bottom of the U-shaped stirrup is clamped onto the forming core mold 2 by the bottom clamping assembly 42 to prevent the bottom of the U-shaped stirrup from deforming; at the same time, it can also prevent the U-shaped stirrup from moving downward as a whole, causing the bending point of the U-shaped stirrup to move upward, further ensuring the forming effect.

[0031] Furthermore, in this embodiment, the bottom clamping assembly 42 includes a lifting drive 421 and a bottom clamping member 422 for clamping the bottom of the U-shaped stirrup onto the forming core mold 2, and the lifting drive 421 is connected to the bottom clamping member 422. The lifting drive 421 drives the bottom clamping member 422 to move up and down, thereby clamping or loosening the bottom of the U-shaped stirrup and the forming core mold 2, and the structure is simple and reasonable. Among them, the lifting drive 421 can be, for example, a cylinder, an oil cylinder, or an electric push rod.

[0032] Furthermore, in this embodiment, the bottom pressing member 422 is a pressing plate. The pressing plate has a large force application area, which can make the bottom of the U-shaped stirrup fit better with the forming core mold 2, further ensuring the forming effect.

[0033] Furthermore, in this embodiment, the forming mechanism 3 includes a swing bending assembly 31 located on both sides of the forming core mold 2, and the swing bending assembly 31 includes a swing arm 313 hinged to the frame 1, a bending member 312 provided on the swing arm 313, and a swing driving member 311 connected to the swing arm 313. When the bending member 312 bends the U-shaped stirrup, the bending force point swings along with the bending of the U-shaped stirrup, the bending force point is stable, and the forming is stable.

[0034] Furthermore, in this embodiment, the bending member 312 is a bending roller, which can reduce friction and reduce damage to the U-shaped stirrups, while ensuring reliable contact with the U-shaped stirrups during the bending process.

[0035] Furthermore, in this embodiment, the forming core mold 2 is L-shaped, the horizontal portion of the forming core mold 2 is used for forming and the vertical portion is connected to the frame 1. By setting the L-shaped forming core mold 2, after the U-shaped stirrup is bent, the longitudinal steel bars (such as Figure 3 The U-shaped stirrups are bent and then separated from the horizontal portion of the L-shaped core mold 2 (as shown by the middle arrow), and the next U-shaped stirrup is moved to the core mold 2. The above steps are repeated to achieve continuous forming of the U-shaped stirrups.

[0036] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as above in the preferred embodiment, it is not used to limit the utility model. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the methods and technical contents disclosed above without departing from the spirit and technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model, still fall within the scope of protection of the technical solution of the utility model.
