[0032] Embodiment 1
[0033] Figures 3 to 5An embodiment of the stirrup forming core mold of the utility model is shown. The stirrup forming core mold of this embodiment includes a core mold body 1. The bottom of the core mold body 1 is provided with lower longitudinal steel bar positioning parts 11 on the left and right sides, and the upper part of the core mold body 1 is provided with upper longitudinal steel bar positioning holes 12.
[0034] In the stirrup forming core mold of the present embodiment, when forming the stirrups, the transverse steel bar 63 and the lower longitudinal steel bar 61 have been pre-welded and fixed. First, the core mold body 1 cooperates with the forming mechanism such as the bending mechanism to bend the transverse steel bar 63. Then, the lower longitudinal steel bar 61 and the upper longitudinal steel bar 62 are moved to the next workstation along the longitudinal direction (the length direction of the lower longitudinal steel bar 61), the upper longitudinal steel bar 62 is moved along the upper longitudinal steel bar positioning hole 12, and the lower longitudinal steel bar 61 is moved along the lower longitudinal steel bar positioning portion 11. Finally, the upper longitudinal steel bar 62 and the bent transverse steel bar 63 are welded at the next workstation. The above steps are repeated to realize continuous forming of stirrups. The stirrup forming core mold of this embodiment positions the lower longitudinal steel bar 61 through the lower longitudinal steel bar positioning part 11 to prevent the transverse steel bar 63 from being offset from the position of the core mold body 1 when bending, and the forming effect is good; the upper longitudinal steel bar 62 is circumferentially positioned through the upper longitudinal steel bar positioning hole 12, so that when the upper longitudinal steel bar 62 and the bent transverse steel bar 63 are moved to the next welding station, there is no need to reposition the upper longitudinal steel bar 62 and the bent transverse steel bar 63, and the relative position of the upper longitudinal steel bar 62 and the bent transverse steel bar 63 is fixed, which is conducive to the accuracy of the subsequent welding position and improves the consistency and stability of the cross-section of the steel cage.
[0035] Furthermore, in the present embodiment, two upper longitudinal steel bar positioning holes 12 are provided and arranged one-to-one above the two lower longitudinal steel bar positioning parts 11. The two upper longitudinal steel bar positioning holes 12 are arranged one-to-one above the two lower longitudinal steel bar positioning parts 11, and the lower longitudinal steel bar positioning parts 11 and the upper longitudinal steel bar positioning holes 12 form a rectangular structure, so that the lower longitudinal steel bars 61 and the upper longitudinal steel bars 62 moving along the lower longitudinal steel bar positioning parts 11 and the upper longitudinal steel bar positioning holes 12 are also arranged in a rectangular shape, which is suitable for the production of common rectangular steel bar cages. Of course, in other embodiments, the number and position of the upper longitudinal steel bar positioning holes 12 can be adjusted according to steel bar cages of different shapes, which will not be repeated here.
[0036] Further, in this embodiment, the two upper longitudinal steel bar positioning holes 12 and the two lower longitudinal steel bar positioning parts 11 are symmetrically arranged on both sides of the core mold body 1. By symmetrically arranging the two upper longitudinal steel bar positioning holes 12 on both sides of the core mold body 1 and symmetrically arranging the two lower longitudinal steel bar positioning parts 11 on both sides of the core mold body 1, the consistency of the positioning of the lower longitudinal steel bar 61 by the lower longitudinal steel bar positioning parts 11 on the left and right sides is improved, and the consistency of the positioning of the upper longitudinal steel bar 62 by the upper longitudinal steel bar positioning holes 12 on the left and right sides is improved.
[0037] Furthermore, in this embodiment, the upper longitudinal steel bar positioning hole 12 is an inner hole of the pipe fitting. The pipe fitting has a simple structure and can realize circumferential positioning of the upper longitudinal steel bar 62, and when the upper longitudinal steel bar 62 moves along the pipe fitting, the pipe fitting can also provide a good guiding effect.
[0038] Furthermore, in this embodiment, a mounting groove 13 is provided on the core mold body 1, and the pipe fitting is arranged in the mounting groove 13. Since the transverse reinforcement 63 needs to be bent around the core mold body 1, by arranging the pipe fitting in the mounting groove 13, that is, the pipe fitting is embedded in the core mold body 1, the transverse reinforcement 63 is prevented from interfering with the pipe fitting when being bent.
[0039] Furthermore, in this embodiment, the pipe member penetrates the core mold body 1. By the pipe member penetrating the core mold body 1, that is, the pipe member is longer than the core mold body 1, the pipe member can provide guidance and positioning for the upper longitudinal steel bar 62 before the upper longitudinal steel bar 62 reaches the core mold body 1, further improving the guidance and positioning effect.
[0040] Furthermore, in this embodiment, the lower longitudinal steel bar positioning portion 11 is a positioning groove. The lower longitudinal steel bar 61 is positioned by the positioning groove, and the structure is simple and reliable.
[0041] Embodiment 2
[0042] Figures 6 to 9 Another embodiment of the stirrup forming core mold of the utility model is shown. The structure of the stirrup forming core mold of this embodiment is basically the same as that of the first embodiment, and the differences include:
[0043] In this embodiment, a guide member 2 is provided at the bottom of the core mold body 1. The transverse reinforcement 63 may be bent and deformed sometimes, and the guide member 2 is provided to guide the transverse reinforcement 63 to prevent the transverse reinforcement 63 with a large bend from colliding with the core mold body 1.
[0044] Furthermore, in this embodiment, the guide member 2 is a guide plate, both ends of which are inclined upward, and can guide the forward or reverse movement of the transverse reinforcement 63. Of course, in other embodiments, only one end of the guide plate can be inclined upward. The upwardly inclined guide plate can guide and press down the transverse reinforcement 63 with a large bend, so that the transverse reinforcement 63 can smoothly move through the core mold body 1.
[0045] Furthermore, in this embodiment, the width of the guide plate is smaller than the width of the core mold body 1, and the lower longitudinal steel bar positioning portion 11 is a groove formed between the side of the guide plate and the bottom surface of the core mold body 1. Since the guide plate having a width smaller than the core mold body 1 is provided, there is no need to provide a groove at the bottom of the core mold body 1 as in the first embodiment, and a groove capable of positioning the lower longitudinal steel bar 61 can be formed between the side of the guide plate and the bottom surface of the core mold body 1, and the structure is simple and reasonable.
[0046] 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 according to 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.
