Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reinforcing bar limiting equipment, and more particularly to a reinforcing bar limiting mechanism and a cage weaving machine. BACKGROUND

[0002] The cage weaving machine is a device for weaving a reinforcing cage, which arranges a plurality of reinforcing bars into a reinforcing bar frame in a certain shape, such as a polygon or a cylinder, and spirally winds a stirrup along the outer periphery of the reinforcing bar frame to form the reinforcing cage.

[0003] The existing cage weaving machine includes a welding reinforcing bar mechanism, which includes an electrode disc and a welding arm rotating around the electrode disc, and the welding arm has a groove for accommodating the stirrup. The edge portion of the electrode disc is provided with a plurality of grooves for accommodating reinforcing bars, and each groove can accommodate one reinforcing bar. The reinforcing bars in the plurality of grooves form a reinforcing bar frame along the outer periphery of the electrode disc. During the longitudinal forward movement of the reinforcing bar frame, the welding arm drives the stirrup to rotate around the reinforcing bar frame, so that the stirrup is in contact with each reinforcing bar and is welded integrally. The reinforcing bar frame continuously advances, and the welding arm continuously drives the stirrup to rotate around the reinforcing bar frame, thereby completing the welding of the reinforcing bar frame and the stirrup.

[0004] However, during the welding process, the reinforcing bars are long, and the reinforcing bars in the grooves of the electrode disc are easily affected by the other end behind them in the longitudinal direction, which leads to the situation that the reinforcing bars escape from the grooves of the electrode disc, thereby affecting the shape of the reinforcing bar frame, leading to the fact that the shape of the reinforcing cage produced does not conform to the original design, and affecting the welding of the reinforcing bar and the stirrup, leading to the fact that the woven reinforcing cage is unqualified and cannot be used in production.

[0005] Therefore, how to solve the swing and escape of the reinforcing bars in the grooves of the electrode disc has become a technical problem to be solved by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0040] The core of this application is to provide a rib limiting mechanism to solve the problem of ribs swinging and escaping in the electrode disk groove.

[0041] Another core aspect of this application is to provide a cage-making machine having the aforementioned reinforcing bar limiting mechanism.

[0042] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0044] In this embodiment, the Y-axis is in the longitudinal direction, that is, the length direction of the reinforcing bar 5, and the direction of travel of the reinforcing bar 5 is forward; the X-axis is in the transverse direction, that is, the length direction of the mounting base 1 and the length direction of the connecting plate 3; the Z-axis is in the vertical direction, that is, the direction perpendicular to the plane formed by the X-axis and the Y-axis.

[0045] Example 1

[0046] See Figures 1 to 7 This embodiment provides a reinforcing bar limiting mechanism 100, including a mounting base 1 and a limiting component 2. The edge of the mounting base 1 is provided with a plurality of limiting grooves 11 for accommodating reinforcing bars 5. The limiting component 2 includes a plurality of limiting members 21 that are rotatably installed at the limiting grooves 11 and a driving mechanism 22 for driving the limiting members 21 to deflect. The limiting members 21 are provided in a one-to-one correspondence with the limiting grooves 11. After the driving mechanism 22 drives the limiting members 21 to rotate and close in the direction close to the limiting grooves 11, the limiting members 21 and the limiting grooves 11 combine to form a limiting channel for the longitudinal passage of the reinforcing bars 5.

[0047] Specifically, when the reinforcing bar limiting mechanism 100 is installed at the longitudinal rear end of the welding bar mechanism 200, the limiting channel can limit the reinforcing bar so that the reinforcing bar 5 at the rear end of the electrode plate is in a preset position, so as to ensure that the reinforcing bar 5 located in the groove of the electrode plate is not affected by the other end of its longitudinal rear end and is not displaced, thereby avoiding problems caused by the displacement of the reinforcing bar 5 and improving the production qualification rate of the reinforcing bar cage.

[0048] In detail, the reinforcing bar limiting mechanism 100 can be mounted on the frame 4 of the cage weaving machine via the mounting base 1. The limiting member 21 is rotatably mounted at the limiting groove 11. As long as the limiting member 21 can be deflected relative to the mounting base 1 and cooperates with the limiting groove 11 to form a limiting channel, it is acceptable. There are various deflection mounting forms between the limiting member 21 and the mounting base 1, which are not limited here. Preferably, the mounting base 1 is provided with multiple longitudinal first shafts 12, each corresponding to a limiting groove 11. The two ends of the first shaft 12 are located on the longitudinal sides of the mounting base 1, respectively. The limiting member 21 has a longitudinal through hole, through which the limiting member 21 is hinged to one end of the first shaft 12. The driving mechanism 22 can be hydraulically driven, pneumatically driven, mechanically driven, electrically driven, etc., as long as it can drive the limiting member 21 to deflect. The specific type is not limited. The driving mechanism 22 drives the limiting member 21 to rotate and close in the direction of approaching the limiting groove 11. This means that the driving mechanism 22 drives the limiting member 21 to deflect so that the limiting member 21 and the limiting groove 11 are misaligned in the longitudinal direction to form a limiting channel. The specific degree of closing is not strictly limited, as long as the reinforcing member 5 does not leave the limiting channel. Therefore, there may be transverse and / or longitudinal gaps between the limiting member 21 and the limiting groove 11. Preferably, there are no longitudinal gaps between the limiting member 21 and the limiting groove 11, and the limiting member 21 is at least partially located at the opening of the limiting groove 11.

[0049] Based on the above scheme, see Figures 1 to 5 A limiting member 21 is installed at each of the longitudinal ends of the first shaft 12 of the mounting base 1. Both limiting members 21 can deflect laterally. Preferably, the two limiting members 21 deflect laterally in opposite directions, that is, one deflects clockwise and the other deflects counterclockwise. The limiting channel can be extended by the limiting members 21 on both sides of the limiting groove 11 to better limit the reinforcing bar 5, and to still limit it if one of them has an error. The longitudinal distance between the two limiting members 21 is L1, and the longitudinal distance between either of the two limiting members 21 and the limiting groove 11 is L2. L1 is greater than L2, thus further limiting the possibility of longitudinal swing of the reinforcing bar 5 and further limiting the longitudinal movement of the reinforcing bar 5.

[0050] Based on the above scheme, the limiting members 21 on both sides of the same limiting groove 11 are set with different deflection angles. In this way, one of the limiting members 21 on both sides forms a limiting channel M1 with the limiting groove 11, and the other forms a limiting channel M2 with the limiting groove 11. Preferably, the limiting channel at the front end is smaller than the limiting channel at the rear end, so as to more accurately limit the reinforcing bar 5.

[0051] Based on the above scheme, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The limiting component 2 also includes two or more connecting plates 3 that are movably mounted on the mounting base 1. The tail of the limiting member 21 is connected to the corresponding connecting plate 3 via a lever 31. Each connecting plate 3 is connected to a drive mechanism 22 to drive the lever 31 to move laterally.

[0052] Specifically, two connecting plates 3 are disposed on both longitudinal sides of the mounting base 1. Each connecting plate 3 has multiple longitudinal levers. Each connecting plate 3 on each side is connected to a corresponding limiting member 21 via a lever 31. The limiting member 21 has a connecting hole 221 at its tail, through which the lever 31 is connected. The multiple levers 31 of the connecting plate 3 can simultaneously actuate the multiple limiting members 21 corresponding to them, thereby forming multiple limiting channels to facilitate the simultaneous limiting of multiple reinforcing bars 5. The number of connecting plates 3 is not limited; one connecting plate 3 corresponds to multiple limiting members 21, which can be determined according to actual needs. Figure 1 , Figure 3 Two connecting plates 3 are provided on each of the longitudinal sides of the mounting base 1. The two connecting plates 3 on the same longitudinal side are set at the top and bottom vertically respectively, so that the upper and lower rows of reinforcing bars 5 can be limited respectively. Of course, more than one connecting plate 3 can be added on the basis of the two connecting plates 3, and all connecting plates 3 are connected end to end in the plane formed by the X-axis and Z-axis, which can be determined according to actual needs.

[0053] Based on the above scheme, see Figure 1 , Figure 3 , Figure 5 The connecting plate 3 has a strip-shaped hole 32. The mounting base 1 has a longitudinal second shaft 13, with its two ends located on the longitudinal sides of the mounting base 1. The two ends of the second shaft 13 pass through the strip-shaped hole 32 on the connecting plate 3 on their respective sides and are connected to the driving end of the driving mechanism 22. The driving mechanism 22 is mounted on the connecting plate 3, making the structure more compact and reducing the area occupied. The driving mechanism 22 is a telescopic power source; its specific form is not limited, as long as it can drive the connecting plate 3 to move laterally through telescopic movement, thereby causing the limiting member 21 to deflect. The direction of the length of the strip-shaped hole 32 is also the direction of movement of the connecting plate 3.

[0054] Based on the above scheme, in order to limit the lateral translation distance of the connecting plate 3 and limit the deflection angle of the limiting member 21, a translation limiting component 33 is also provided, which includes a fixed base 331 and a limiting stop 332 installed on the fixed base 331. The installation position of the fixed base 331 is not strictly limited. Preferably, the fixed base 331 is installed at at least one end of the two ends of the strip hole 32. The fixed base 331 has a transverse through hole. The limiting stop 332 is not strictly limited, as long as it can be laterally displaced or retracted. Preferably, the limiting stop 332 is a double-ended bolt. The bolt of the limiting stop 332 passes through the hole of the fixed base 331 and is fixed to the fixed base 331 by nuts on its transverse sides. Of the two ends of the double-ended bolt, one end is away from the second axis 13, and the other end faces the second axis 13. During the lateral translation of the connecting plate 3, the end of the limiting stop 332 facing the second shaft 13 abuts against the second shaft 13 to control the lateral translation distance of the connecting plate 3. In this embodiment, the lateral translation distance of the connecting plate 3 is limited by adjusting the lateral distance between the end of the limiting stop 332 facing the second shaft 13 and the second shaft 13. Specifically, simply rotating the limiting stop 332 towards or away from the second shaft 13 can control the lateral translation distance of the connecting plate 3. The number of translation limiting components 33 can be one, installed at one end of the strip hole 32, or two, installed at both ends of the strip hole 32 respectively.

[0055] Based on the above scheme, see Figure 1 , Figure 4 , Figure 6 To facilitate the smooth and rapid lateral relative movement of the connecting plate 3 on the mounting base 1, a lateral moving track 14 is provided on one of the mounting base 1 and the connecting plate 3, and a moving block 34 that cooperates with the moving track 14 is provided on the other.

[0056] Based on the above scheme, the shape of the limiting member 21 is not strictly limited, as long as it can perform the function of limiting the reinforcing bar 5. Preferably, the limiting member 21 has a V-shaped, U-shaped, or arc-shaped reinforcing bar groove. In this way, the limiting channel formed by the cooperation of the reinforcing bar groove and the limiting groove 11 can better limit the reinforcing bar 5 within the limiting channel. See [reference needed]. Figures 1 to 4 In particular, the arc-shaped reinforcing groove can fit against part of the outer periphery of the reinforcing bar 5.

[0057] Based on the above scheme, in order to make it easier for the reinforcing bar 5 to pass through the limiting groove 11, the groove width of the limiting groove 11 is greater than or equal to the groove width of the reinforcing bar limiting groove.

[0058] Example 2

[0059] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0060] SeeFigure 7 , Figure 8 This utility model provides a cage weaving machine, which includes the reinforcing bar limiting mechanism 100 as described in Embodiment 1 and a welding bar mechanism 200 disposed at the longitudinal front end of the reinforcing bar limiting mechanism 100. The reinforcing bar limiting mechanism 100 is mounted on a frame 4, the frame 4 is mounted on a support frame 41, and the welding bar mechanism 200 is mounted on the frame 4 or the support frame 41. The welding bar mechanism 200 has multiple longitudinally arranged grooves 201 arranged laterally. The reinforcing bar 5 is placed longitudinally in the grooves 201. The limiting member 21 in the reinforcing bar limiting mechanism 100 rotates and forms a limiting channel together with the limiting groove 11, so that the reinforcing bar 5 is confined within the limiting channel. The welding arm in the welding bar mechanism 200 drives the stirrup to weld laterally to the reinforcing bar 5 in each groove 201, so that the reinforcing bar 5 in all grooves 201 are welded to the stirrup and form an integral reinforcing cage.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
