[0025] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figures 1 to 7 An embodiment of the reinforcing cage end bending device of the present application is shown. The reinforcing cage end bending device of the embodiment includes a frame 1 and a bending mechanism 2 arranged on the frame 1, and further includes a reinforcing cage positioning assembly, a support platform 3, and a driving mechanism 7 capable of lifting the support platform 3, the driving mechanism 7 being arranged on the frame 1.

[0027] The steel bar cage end bending device of the embodiment is used in the following way: first, the steel bar cage 8 that has been assembled and welded is placed on the support platform 3, the support platform 3 and the steel bar cage 8 are driven by the driving mechanism 7 to be lowered in place, the accurate positioning of the steel bar cage 8 is completed by the steel bar cage positioning assembly, and then the end bending of the steel bar cage 8 is completed by the bending mechanism 2. During the bending process, the steel bar cage positioning assembly ensures that the position of the steel bar cage 8 does not deviate, thereby ensuring the bending quality. After the end bending, the support platform 3 and the steel bar cage 8 are driven by the driving mechanism 7 to be raised as a whole, which is convenient for discharging. The steel bar cage end bending device has a simple structure, a high degree of automation, and convenient loading and unloading of the steel bar cage 8, which is conducive to improving the processing efficiency. The longitudinal direction is the length direction of the steel bar cage 8, and correspondingly, the transverse direction is the direction perpendicular to the length direction of the steel bar cage 8 in the top view plane. The bending mechanism 2 can be any mechanism that can realize the bending of the steel bar cage 8, and the specific structure is not described here.

[0028] Further, in the embodiment, the support platform 3 is provided with a steel bar cage longitudinal guide 4. The steel bar cage longitudinal guide 4 can provide a guiding effect for the steel bar cage 8 to prevent the steel bar cage from deviating during movement.

[0029] Further, in the embodiment, the steel bar cage longitudinal guide 4 is a U-shaped guide cover with the opening facing downward. The U-shaped guide cover with the opening facing downward can cooperate with the support platform 3 to provide a good guiding effect, effectively preventing the position of the steel bar cage 8 from deviating, and when the guide cover drives the steel bar cage 8 to separate from the support platform 3, the steel bar cage 8 can automatically fall down under the action of gravity.

[0030] Further, in the embodiment, the support platform 3 is further provided with a transverse moving guide rail 41 and a transverse moving driving member 42 (such as a gas cylinder, an oil cylinder, or a screw nut pair) for driving the guide cover to move transversely, and the guide cover is arranged on the transverse moving guide rail 41. Referring to Figure 7 After the end bending of the steel bar cage 8 is completed, the driving mechanism 7 is actuated to drive the support platform 3, the guide cover, and the steel bar cage 8 to rise to a high point as a whole. At this time, the steel bar cage 8 is separated from the steel bar cage longitudinal positioning assembly 5 and the steel bar cage transverse positioning assembly 6, the transverse moving driving member 42 drives the guide cover and the steel bar cage 8 to move transversely along the transverse moving guide rail 41, and when the guide cover separates from the support platform 3, the steel bar cage 8 falls downward under the action of gravity, completing automatic unloading. The transverse space is fully utilized, and compared with longitudinal unloading, the structure of the embodiment is simpler and more compact, more reasonable, the unloading process is smooth, and the efficiency is high. After unloading, the transverse moving driving member 42 drives the guide cover to reset, preparing for the bending of the next steel bar cage 8.

[0031] When the reinforcement cage 8 is placed in the guide cover, the guide cover itself can limit the lateral movement of the reinforcement cage 8, and preferably, positioning members (such as positioning plates, positioning cards, etc.) and positioning driving members (such as air cylinders, oil cylinders or screw-nut pairs, etc.) for driving the positioning members to reciprocate can be further arranged on the guide cover to limit the longitudinal movement of the reinforcement cage 8. When the positioning members abut against the reinforcement cage 8, the positioning of the reinforcement cage 8 is achieved, and after the positioning members are separated from the reinforcement cage 8, the reinforcement cage 8 can move longitudinally in the guide cover or fall downward.

[0032] Further, in the embodiment, the driving mechanism 7 includes two parallel and equal-length connecting rods 71 and a swing driving member 72 for driving the connecting rods 71 to swing, one end of the connecting rod 71 is hinged to the support platform 3, and the other end is hinged to the rack 1. See Figure 4 The two parallel and equal-length connecting rods 71 can constitute a parallelogram linkage, which can swing to one end of the rack 1 during feeding, facilitating the reinforcement cage 8 to be inserted into the guide cover. During the transfer of the reinforcement cage 8, the reinforcement cage 8 can be ensured to be always in a horizontal state, which facilitates the placement of the reinforcement cage 8 before bending and the separation after bending, and the structure is simple and stable. Of course, in other embodiments, the driving mechanism 7 can also use a linear motion mechanism in the vertical and horizontal directions instead of the parallelogram linkage, which can also complete the same action, but compared with the parallelogram linkage, the structure will be more complex and the cost will be higher.

[0033] As a preferred embodiment, the swing driving member 72 is a telescopic structure (such as an air cylinder, an oil cylinder or an electric push rod, etc.), one end of the swing driving member 72 is hinged to the rack 1, and the other end is hinged to one of the connecting rods 71. The telescopic movement of the swing driving member 72 can drive the connecting rod 71 to swing, and the structure is simple and reasonable.

[0034] In the embodiment, the reinforcement cage positioning assembly includes a reinforcement cage lateral positioning assembly 6, which includes a middle positioning plate 61 and two side positioning plates 62, and a positioning part for positioning the longitudinal reinforcement 81 in the reinforcement cage 8 is formed between the middle positioning plate 61 and the side positioning plate 62, i.e. the longitudinal reinforcement 81 in the reinforcement cage 8 is positioned between the middle positioning plate 61 and the side positioning plate 62. See Figure 5 The reinforcement cage lateral positioning assembly 6 can effectively limit the lateral position of the reinforcement cage 8, and when the longitudinal reinforcement 81 is subjected to the force of the bending mechanism 2, only the longitudinal reinforcement 81 is bent, and there is no force between the longitudinal reinforcement 81 and the hoop reinforcement 82, and the structure is simple and effective.

[0035] Further, in the embodiment, the upper sides of the middle positioning plate 61 and the side positioning plate 62 are provided with guide inclined surfaces 63. The guide inclined surfaces 63 facilitate the positioning of the longitudinal reinforcement 81, and can correct the possible lateral deformation of the longitudinal reinforcement 81, and the structure is simple and reasonable.

[0036] Specifically refer to Figure 6 Wherein, the reinforcement cage positioning assembly further comprises a reinforcement cage longitudinal positioning assembly 5, which can be a first longitudinal positioning plate 51 matched with the hoop reinforcement 82 in the reinforcement cage 8, and the two first longitudinal positioning plates 51 are arranged at the two ends of the rack 1. The two first longitudinal positioning plates 51 are matched with the two hoop reinforcements 82, which can effectively limit the longitudinal displacement of the reinforcement cage 8, and the structure is simple and reliable. Preferably, a guide inclined surface can also be arranged on the upper side of the first longitudinal positioning plate 51 to facilitate the positioning of the hoop reinforcement 82.

[0037] Alternatively, the reinforcement cage longitudinal positioning assembly 5 can also be a second longitudinal positioning plate 52, and the second longitudinal positioning plate 52 is provided with a V-shaped groove 53 matched with the hoop reinforcement 82 in the reinforcement cage 8. After the hoop reinforcement 82 is lowered into the V-shaped groove 53, its longitudinal displacement is limited, thereby effectively limiting the longitudinal displacement of the reinforcement cage 8, and the structure is simple and reliable.

[0038] As a preferred embodiment, the rack 1 is provided with a bending mechanism 2 and a reinforcement cage transverse positioning assembly 6 at both ends, and the support platform 3 is located between the two reinforcement cage transverse positioning assemblies 6. The reinforcement cage 8 can be bent at both ends at the same time, which is beneficial to further improve the bending efficiency and keep the force balance of both ends during the operation of the device.

[0039] The reinforcement cage end bending device of the present application is used, the reinforcement cage 8 which has been assembled and welded is placed in the reinforcement cage longitudinal guide 4, the driving mechanism 7 drives the support platform 3, the reinforcement cage longitudinal guide 4 and the reinforcement cage 8 to move vertically and longitudinally as a whole, so that the transverse position of the reinforcement cage 8 can be prevented from changing, and the accurate positioning of the reinforcement cage 8 is finally completed smoothly, then the bending mechanism 2 completes the bending of the end of the reinforcement cage 8, and the longitudinal positioning assembly 5 and the transverse positioning assembly 6 of the reinforcement cage ensure that the position of the reinforcement cage 8 does not deviate during the bending process, thereby ensuring the bending quality. The reinforcement cage end bending device of the present application has the advantages of simple structure, high automation, convenient loading and unloading of the reinforcement cage 8 as a whole, and high processing efficiency.

Any person skilled in the art can make many possible changes and modifications to the technical solutions of the present application, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solutions of the present application, by using the technical contents disclosed above.
