The reinforcement cage is usually a cage-shaped reinforcement framework formed by binding a plurality of reinforcements according to a predetermined binding form, please refer to fig. 1, which is a schematic structural diagram of the reinforcement cage 200 when the reinforcement cage straightening device 100 provided by the embodiment of the present application performs straightening operation, the reinforcement cage 200 provided may include a plurality of reinforcements and a ring reinforcement, wherein the reinforcements may be substantially linear reinforcements, wherein the extending directions of the plurality of reinforcements are substantially the same, the plurality of reinforcements are arranged around a central line at intervals, the plurality of reinforcements are substantially located on the same ring, and the ring reinforcement is bound around the peripheries of the plurality of reinforcements. After the steel reinforcement cage is accomplished in processing, because reinforcing bar itself warp easily, the tip of the reinforcing bar of steel reinforcement cage receives exogenic action usually easily and takes place to buckle, for example, the reinforcing bar buckles to the inboard of steel reinforcement cage or the outside of steel reinforcement cage easily, and when the installation end plate flange, the reinforcing bar of steel reinforcement cage and the unable one-to-one alignment of mounting hole on the end plate flange for many reinforcing bars of steel reinforcement cage can't insert accurately to a plurality of mounting holes of end plate flange. The reinforcement cage 200 may also be a reinforcement cage with other shapes, for example, a plurality of reinforcements may be enclosed into a rectangular ring shape or an elliptical ring shape, etc., and the following ring-shaped reinforcement cage 200 is taken as an example to illustrate the structure and principle of the reinforcement cage straightening device 100:
referring to fig. 1 and 2, the present embodiment provides a reinforcement cage straightening apparatus 100 for straightening a reinforcement cage, including a straightening device 110, where the straightening device 110 includes an external pressing mechanism 111, an internal expanding mechanism 112, and a driving mechanism 113, the internal expanding mechanism 112 is disposed inside the external pressing mechanism 111, and the driving mechanism 113 is used for driving the external pressing mechanism 111 to move.
Referring to fig. 3, in the present embodiment, the orthotic device 110 may include a mounting plate 114 and a mounting ring 115, the mounting plate 114 is disposed opposite to the mounting ring 115, wherein the mounting plate 114 may be used to mount the internal expansion mechanism 112, and the mounting ring 115 may be used to mount the external pressure mechanism 111 or the driving mechanism 113. The mounting ring 115 is generally annular in configuration. In addition, in some embodiments, the mounting ring 115 may also be a rectangular ring, an elliptical ring, or a ring structure with other shapes, which may be adjusted according to actual requirements. Coupling between mounting ring 115 and mounting disk 114 may be via coupling assembly 1151, and coupling assembly 1151 may include a plurality of coupling rods, which may be disposed about the axis of mounting ring 115, each of which may be secured between mounting disk 114 and mounting ring 115.
Referring to fig. 1 and 3, the external pressing mechanism 111 includes at least two external pressing portions 1111, and the at least two external pressing portions 1111 are disposed around a center line X, wherein the center line X may be substantially parallel to the axis of the mounting ring 115. As an example, a plurality of outer presses 1111 may be spaced around the center line X, and each outer press 1111 may be disposed toward a central region of the mounting ring 115 and may be movably disposed substantially in a radial direction of the mounting ring 115 to be selectively close to or away from the central region of the mounting ring 115. The number of the outer pressing portions 1111 may be the same as the number of the reinforcement bars of the reinforcement cage 200, and each outer pressing portion 1111 may correspond to one reinforcement bar of the reinforcement cage 200 to provide a certain amount of correction force for the corresponding reinforcement bar during the correction work. In addition, the number of the external pressing portions 1111 may also be less than or more than the number of the steel bars of the steel bar cage 200, and may be specifically adjusted according to actual needs.
With continued reference to fig. 2 and 3, the driving mechanism 113 is configured to drive the outer pressing portion 1111 to move toward the inner expanding mechanism 112 to provide a corrective force to the reinforcing bar, in some embodiments, the driving mechanism 113 may include at least two outer pressing cylinders 1131, the at least two outer pressing cylinders 1131 may be spaced around the center line X, a piston rod of each outer pressing cylinder 1131 may be substantially directed toward a central region of the mounting ring 115, wherein the piston rod of each outer pressing cylinder 1131 is drivingly connected to one outer pressing portion 1111. Wherein, the cylinder body of each outer pressure cylinder 1131 can be fixed on the ring surface of the mounting ring 115. Because the deformation of each steel bar of the steel bar cage 200 before straightening can have differences, each external pressing cylinder 1131 is adopted to drive one external pressing part 1111, so that the movement of each external pressing part 1111 is independent, and in the straightening process, the expansion and contraction amount of the piston rod of each external pressing cylinder 1131 can be controlled by the deformation of each steel bar, so that the straightening force with corresponding magnitude can be applied to the corresponding steel bar.
Referring to fig. 1 and 3, the internal expansion mechanism 112 is disposed inside the outer pressing portions 1111 and forms a gap 1152 for inserting the reinforcement cage 200 with each of the outer pressing portions 1111, and the internal expansion mechanism 112 is configured to expand a plurality of reinforcements of the reinforcement cage 200 toward the outer circumference of the reinforcement cage 200. The phrase "expand to the periphery of the reinforcement cage" means that the plurality of reinforcements of the reinforcement cage 200 are deformed (e.g., bent) or displaced toward the outside of the reinforcement cage 200 when being subjected to an external expansion force, so that the external diameter of the expanded portion of the reinforcement cage 200 is increased, and the internal expansion mechanism 112 can expand the external diameter of the portion of the reinforcement cage 200 to a predetermined external diameter.
As an example, during outward expansion of the internal expansion mechanism 112, the internal expansion mechanism 112 can provide a substantially radial corrective force to each of the bars of the reinforcement cage 200, such that each of the bars is displaced or deformed radially and towards the corresponding outer press 1111 to a certain extent.
The internal expansion mechanism 112 may have a constant outer diameter dimension or may have a variable outer diameter dimension, wherein the outer diameter dimension of at least a portion of the internal expansion mechanism 112 may be greater than or equal to the inner diameter dimension of the reinforcement cage 200 prior to straightening. In some correction applications, the ends of a plurality of steel bars of some steel bar cages 200 to be corrected are bent towards the inner sides of the steel bar cages after being deformed, so that the inner diameter of the end positions of the steel bar cages 200 is smaller, and when the internal expansion mechanism 112 extends into the steel bar cages, the inner diameter of the ends of the steel bar cages 200 is expanded due to the fact that the outer diameter of the internal expansion mechanism 112 is larger than the inner diameter of the steel bar cages.
In some embodiments, as shown in fig. 3 and 4, the internal expansion mechanism 112 may include an internal expansion portion 1121 and a driving cylinder 1122, the driving cylinder 1122 being configured to drive the internal expansion portion 1121 in a direction parallel to the centerline X and apply a corrective force to the rebar during the movement toward the external pressing portion 1111. This facilitates insertion into reinforcement cage 200 to rapidly expand the reinforcement bars of reinforcement cage 200 outwardly as inner expansion 1121 moves in the direction of centerline X.
As an example, the inner expansion portion 1121 may have a constant outer diameter, that is, the outer diameter of the inner expansion portion 1121 may not be adjusted, the inner expansion portion 1121 may have a substantially tapered structure, for example, a conical or truncated cone structure, wherein the outer diameter of the inner expansion portion 1121 gradually increases from one end to the other end, when the inner expansion portion 1121 relatively moves toward the reinforcement cage 200 along a direction substantially parallel to the center line X during straightening the reinforcement cage 200, one end of the inner expansion portion 1121 having a smaller outer diameter may be inserted into the reinforcement cage 200 to be straightened first, when the other end of the inner expansion portion 1121 having a larger outer diameter is inserted into the reinforcement cage 200, the inner expansion portion 1121 may gradually expand the reinforcements of the reinforcement cage 200 outward, such that each reinforcement is expanded to a certain outward displacement margin toward the outer periphery of the reinforcement cage 200, the outward displacement margin of the reinforcement is bent inward of the reinforcement cage 200 to a position slightly interfering with the inner side by the outer pressing mechanism 111, because the resilience amount of reinforcing bar, can realize straightening of reinforcing bar after the reinforcing bar kick-backs and target in place for the tip of correcting the many reinforcing bars of the steel reinforcement cage 200 that targets in place can basically counterpoint with a plurality of mounting holes of end plate flange one by one.

The included angle formed between each of the inner expansion rods 1123 and the center line X is substantially equal, and the plurality of inner expansion rods 1123 are arranged obliquely relative to the center line X and are enclosed in a conical shape, so that the outer diameter of the entire inner expansion portion 1121 can be gradually increased from one end to the other end. One end of the inner expansion portion 1121, which has a smaller outer diameter, can be inserted into the reinforcement cage 200 to be straightened, each inner expansion rod 1123 correspondingly expands one reinforcement of the reinforcement cage 200 in the radial direction, and in the process of continuously inserting the reinforcement cage 200, a plurality of reinforcements of the reinforcement cage 200 can be slowly expanded due to the gradual increase of the outer diameter of the inner expansion portion 1121, and the reinforcement can be straightened by matching with the external pressure mechanism 111.
In some embodiments, the inner expansion portion 1121 has a variable outer diameter size, that is, the outer diameter size of the inner expansion portion 1121 is adjustable, and as shown in fig. 3 and 5, as an example, the inner expansion mechanism 112 may include a guide ring 1125 and a fixed disk 1124, the guide ring 1125 is located between the fixed disk 1124 and the driving cylinder 1122, a piston rod of the driving cylinder 1122 passes through the guide ring 1125 and is drivingly connected to the fixed disk 1124, each inner expansion rod 1123 includes a hinge portion 1123a and a connecting portion 1124b and a positioning portion 1124c for positioning the reinforcing bars, and the connecting portion 1124b is connected between the hinge portion 1123a and the positioning portion 1124c and is slidably connected to an outer wall of the guide ring 1125. Angle α gradually increases as drive cylinder 1122 drives fixed disk 1124 away from guide ring 1125.

In the process that the driving cylinder 1122 drives the fixed disc 1124 to be far away from the guide ring 1125, so as to drive each internal expansion rod 1123 to rotate, the included angle between the internal expansion rods 1123 and the center line X is increased, and the positioning portions 1124c are expanded outwards along the radial direction of the reinforcement cage 200, so that the outer diameter of the internal expansion portions 1121 can be increased, and the outer diameter of the reinforcement cage 200 is automatically expanded to a predetermined outer diameter.
During the straightening operation, the fixing plate 1124 may be directed toward the reinforcement cage 200, and a plurality of pieces of steel of the reinforcement cage are aligned with the gap 1152 between each positioning portion 1124c and the outer pressing portion 1111, when the reinforcement cage 200 is relatively close to the fixing plate 1124 along a direction parallel to the central line X, one end of the inner expansion portion 1121, which is connected to the smaller outer diameter of the fixing plate 1124, is first inserted into the reinforcement cage 200, and a plurality of pieces of steel of the reinforcement cage 200 may correspond to the plurality of positioning portions 1124c one to one. When the fixed disc 1124 is driven to be far away from the guide ring 1125 by the driving cylinder 1122, since the piston rod of the driving cylinder 1122 is continuously extended, the fixed disc 1124 drives the hinge portion 1123a of the internal expansion rod 1123 to move forward, the hinge portion 1123a rotates relative to the fixed disc 1124, so that one end of the connecting portion 1124b far away from the hinge portion 1123a is far away from the center line X, during the process of extending the piston rod to the maximum length, the included angle α between each internal expansion rod 1123 and the center line X can be gradually increased, and the outer diameter dimension defined by the plurality of positioning portions 1124c is continuously increased. In the process that the outer diameter size formed by the positioning portions 1124c is gradually increased, the plurality of steel bars of the steel bar cage 200 are gradually expanded to the outer circumference, and the outer pressing mechanism 111 is matched to realize the straightening and shaping of the steel bars.
