Description

Technical Field

[0001] This utility model relates to the field of steel cage production technology, and in particular to an automatic steel cage production equipment. Background Technology

[0002] The production process of reinforcing cages involves winding coiled steel bars (also known as stirrups) around the outside of longitudinal bars and welding them in place. The movement during welding includes rotational and lateral movement of the longitudinal bars. In existing technologies, during the longitudinal bar movement process, some welded cage segments may bend and deform under gravity, affecting the welding accuracy of subsequent longitudinal bars and stirrups. When the cage diameter or the diameter of the longitudinal bars is small, the joint pressure during welding of the longitudinal bars and stirrups also affects the welding quality of the reinforcing cage. Therefore, the minimum cage diameter that existing reinforcing cage production processes can produce is 600mm. The finished product quality of smaller-sized reinforcing cages is limited by welding accuracy, resulting in low production efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0052] This utility model provides an automatic steel cage production equipment, such as... Figures 1-8 As shown, the steel cage 100 includes longitudinal bars 101 and stirrups 102. When the multiple longitudinal bars 101 move along their axial direction and rotate around the central axis of the multiple longitudinal bars 101, the stirrups 102 wrap around the multiple longitudinal bars 101 and are welded and fixed to the longitudinal bars 101. The automatic steel cage production equipment provided by this utility model can realize the laying, straightening, and winding of the stirrups 102, as well as the feeding, moving and rotating of the longitudinal bars 101, thereby improving the welding quality between the stirrups 102 and the longitudinal bars 101 and improving the production efficiency of the steel cage 100.

[0053] The automatic steel cage production equipment provided in this embodiment includes a bottom beam 1, a fixed turntable 2, a movable turntable 3, and a reinforcement device 4. The bottom beam 1 extends along a first direction, and the fixed turntable 2 is fixedly mounted on the bottom beam 1, such as at the end of the bottom beam 1. The fixed turntable 2 is provided with multiple first reinforcing pipes 21, each with an arc-shaped support section 22 at its end. Multiple longitudinal reinforcement bars 101 of the steel cage 100 pass through the first reinforcing pipes 21, and the stirrups 102 of the steel cage 100 are spirally wound. The longitudinal reinforcement 101 is supported on the outer side and during the welding of the longitudinal reinforcement 101 and the stirrup 102 on the arc-shaped support section 22; the movable turntable 3 is movably mounted on the bottom beam 1, and the end of the longitudinal reinforcement 101 is fixed on the movable turntable 3 after passing through the fixed turntable 2. The movable turntable 3 is used to drive the longitudinal reinforcement 101 to move and rotate; the reinforcement device 4 is located on the side of the fixed turntable 2 away from the movable turntable 3. The reinforcement device 4 is coaxially mounted with the fixed turntable 2, and multiple longitudinal reinforcements 101 are sequentially passed through the reinforcement device 4, the fixed turntable 2 and the movable turntable 3.

[0054] The automatic steel cage production equipment provided by this utility model, by setting a first reinforcing pipe 21 on a fixed turntable 2 and setting an arc-shaped support section 22 at the end of the first reinforcing pipe 21, when the stirrups 102 are wrapped around the longitudinal bars 101, the longitudinal bars 101 can be supported on the arc-shaped support section 22 to ensure the spacing and position between the longitudinal bars 101, avoid changes in the cage diameter, and improve the quality of the finished steel cage 100; when the welding device 7 presses the stirrups 102 and the longitudinal bars 101 for welding, the arc-shaped support section 22 can provide stable welding support to ensure welding quality; by setting the reinforcement device 4 coaxial with the fixed turntable 2, it is beneficial to the positional stability between multiple longitudinal bars 101, and avoids positional displacement during the rotation of the steel cage 100. Especially for the longitudinal bars 101 above the welding position, the reinforcement device 4 and the first reinforcing pipe 21 respectively support the longitudinal bars 101 at both ends of the fixed turntable 2, making it easier to weld and improving welding quality; this utility model realizes the automated feeding and welding production of steel cages 100, and improves the production efficiency of steel cages 100.

[0055] In this utility model, the moving motion of the movable turntable 3 on the bottom beam 1 is as follows: Figure 3 As shown, a rack and pinion transmission mechanism can be used, that is, a rack is set on the bottom beam 1, and a gear is set on the movable turntable 3. The drive mechanism drives the gear to rotate, which can drive the entire movable turntable 3 to move the longitudinal rib 101 along the rack. In order to improve the movement stability, guide wheels or the like can be set on the movable turntable 3 for rolling support and guidance. Of course, the movable turntable 3 can also be driven and controlled by a linear module, and this embodiment does not impose any restrictions.

[0056] In some embodiments, the fixed turntable 2 is provided with a plurality of first mounting holes 23, and a plurality of first through-rib tubes 21 are selectively inserted into the plurality of first mounting holes 23 and extend along the axial direction of the fixed turntable 2. The arc-shaped support section 22 is coaxially arranged with the first through-rib tubes 21.

[0057] The position and number of the first reinforcing pipe 21 are determined according to the position and number of the longitudinal bars 101 of the reinforcing cage 100, so as to limit the number of longitudinal bars 101. The first reinforcing pipe 21 can be made of water-inlet or non-metallic material, preferably non-metallic PVC pipe to reduce friction and noise. At least one end of the first reinforcing pipe 21 passes through the side of the fixed turntable 2 facing the movable turntable 3 and has an extension length so as to stably support the longitudinal bars 101 and ensure that the longitudinal bars 101 can be stably positioned horizontally during welding. The outer diameter and inner diameter of the first through-tube 21 are preset according to the diameter of the first mounting hole 23 and the diameter of the longitudinal rib 101, respectively. The outer diameter of the first through-tube 21 is slightly smaller than the diameter of the first mounting hole 23 to ensure that the first through-tube 21 is inserted into the first mounting hole 23 and fixed. The inner diameter of the first through-tube 21 is slightly larger than the diameter of the longitudinal rib 101 to minimize the shaking of the longitudinal rib 101 in the first through-tube 21, and the longitudinal rib 101 can pass through the first through-tube 21 and slide smoothly.

[0058] In some embodiments, the central angle of the arc-shaped support segment 22 is less than 180°. The arc-shaped support segment 22 supports the side of the longitudinal reinforcement 101 opposite to the stirrup 102. This ensures that when the stirrup 102 winds around multiple longitudinal reinforcements 101, the minimum spacing between the longitudinal reinforcements 101 is limited to the multiple arc-shaped support segments 22, preventing diameter changes during winding and affecting the quality of the finished product. Setting the central angle of the arc-shaped support segment 22 to less than 180° is to prevent the stirrup 102 from also winding and fixing the arc-shaped support segment 22 during winding, thus affecting the continued movement of the longitudinal reinforcement 101. Figure 7 As shown, the initial section of the stirrup 102 is fed and led out to the longitudinal reinforcement 101 on the arc-shaped support section 22 and welded and fixed. The welding area is located in the arc-shaped support section 22. The arc-shaped support section 22 is formed by cutting a notch along the axial direction of the first through-tube 21 or by assembling it at the end of the first through-tube 21. The setting of the arc-shaped support section 22 is conducive to applying a pressure connection force when welding the stirrup 102 and the longitudinal reinforcement 101, so as to improve the welding quality and welding efficiency.

[0059] In some embodiments, both the fixed turntable 2 and the movable turntable 3 include a frame 31, a slewing bearing 32, and a disc 33. The frame 31 is mounted on the bottom beam 1. Specifically, the frame 31 of the fixed turntable 2 is fixedly mounted at the end of the bottom beam 1, and the frame 31 of the movable turntable 3 is movably mounted on the bottom beam 1. That is, the movable turntable 3 can drive multiple longitudinal ribs 101 to move and rotate along the length direction of the bottom beam 1 for the forming and welding of the reinforcing cage 100. The slewing bearing 32 includes an inner ring 321 and an outer ring 322. The inner ring 321 is fixed on the frame 31, and the outer ring 322 is rotatably mounted with the inner ring 321 to form a bearing structure. The disc 33 is fixed on the outer ring 322 of the slewing bearing 32. When the outer ring 322 and the disc 33 rotate, they drive the longitudinal ribs 101 to rotate.

[0060] like Figure 6 and Figure 7 As shown, the inner ring 321 of the slewing bearing 32 is fixed on the frame 31, and the circumferential edge of the disc 33 is fixed to the end face of the outer ring 322 of the slewing bearing 32. The disc 33 and the outer ring 322 can be connected and fixed by multiple connecting blocks 323, or by multiple connecting parts provided around the circumference of the disc 33. The connection method is bolt connection. By using the slewing bearing 32, the rotational stability of the longitudinal rib 101 is improved, which is beneficial to drive control and can withstand a large load.

[0061] In some embodiments, the rotational movement of the disk 33 and the outer ring 322 of the slewing bearing 32 is driven and controlled by the drive member 34. The fixed turntable 2 and the movable turntable 3 can share a single drive member 34, that is, the drive member 34 is set on the movable turntable 3 to drive the outer ring 322 and the disk 33 on the movable turntable 3 to rotate. Alternatively, the fixed turntable 2 and the movable turntable 3 can each be provided with a separate drive member 34. However, during production, it is necessary to ensure the synchronization of the two drive members 34, that is, the disk 33 of the fixed turntable 2 and the disk 33 of the movable turntable 3 rotate synchronously. To facilitate the rotation of the slewing bearing 32 or the disk 33, multiple fixed teeth are provided circumferentially on the outer circular surface of the outer ring 322 of the slewing bearing 32 or on the outer circular surface of the disk 33. The output end of the drive member 34 is provided with a drive wheel 341, which meshes with the multiple fixed teeth.

[0062] Specifically, such as Figure 6 and Figure 7 As shown, the outer ring 322 adopts an external gear structure, and the driving member 34 drives the outer ring 322 to rotate through the driving wheel 341. In some embodiments, when the outer diameter of the disk 33 is larger than the outer diameter of the outer ring 322, the disk 33 can also be configured as an external gear meshing with the driving wheel 341 for transmission. The gear transmission connection method has high transmission accuracy and is conducive to controlling the rotation angle of the longitudinal rib 101 so as to accurately weld and position the longitudinal rib 101 and the stirrup 102. The driving member 34 can be a motor and a reducer. Furthermore, the output end of the driving member 34 is provided with a seated bearing 342 to improve the stability of the rotation of the driving wheel 341 and the disk 33.

[0063] In some embodiments, the disc 33 of the movable turntable 3 is provided with a plurality of second mounting holes 331, and a plurality of second reinforcing tubes 332 are selectively inserted into the plurality of second mounting holes 331 and extended along the axial direction of the movable turntable 3. The side wall of the second reinforcing tube 332 is provided with a threaded hole 333, and a threaded bolt is connected in the threaded hole 333 to tighten and fix the longitudinal reinforcing 101 inserted in the second reinforcing tube 332.

[0064] like Figure 3As shown, the threaded hole 333 on the side wall of the second through-rib tube 332 is internally threaded with a bolt. The bolt is screwed into the second through-rib tube 332 to a depth that allows it to press against the longitudinal rib 101, thus fixing the longitudinal rib 101. To increase the connection strength of the bolt, a bolt can be fixed to the side wall of the second through-rib tube 332 to increase the threaded connection length. It should be noted that, to simplify the process, the disc 33 on the fixed turntable 2 and the disc 33 on the movable turntable 3 adopt the same structure; that is, the layout and diameter of the first mounting hole 23 and the second mounting hole 331 on the disc 33 can be the same, facilitating the use of the same specifications for the first through-rib tube 21 and the second through-rib tube 332. The second through-rib tube 332 can be the same as the first through-rib tube 21. Of course, the arc-shaped support section 22 can be omitted from the second through-rib tube 332 to reduce manufacturing costs.

[0065] In some embodiments, the reinforcement device 4 includes a first reinforcement frame 41, which includes a base frame 411, a roller frame 412, and reinforcing bars 413. The base frame 411 is provided with limiting ribs 4111 to limit the lowest position of the longitudinal ribs 101. The roller frame 412 is coaxially connected to the disc 33 of the fixed turntable 2 via a connecting shaft 43. When the disc 33 rotates, it drives the roller frame 412 to rotate synchronously via the connecting shaft 43. A plurality of reinforcing bars 413 are arranged circumferentially around the roller frame 412 and extend along the radial direction of the roller frame 412. The longitudinal ribs 101 can pass between any two adjacent reinforcing bars 413 and be supported on the roller frame 412.

[0066] like Figure 4 As shown, the base frame 411 is fixedly installed, and the base frame 411 is provided with a semi-circular arc-shaped limiting rib 4111 with the opening facing. In this embodiment, the limiting rib 4111 is made of two arc-shaped steel bars, and the two ends of the arc-shaped steel bars are fixed on the base frame 411. Multiple longitudinal ribs 101 are respectively inserted between the dividing rib rods 413. The dividing rib rods 413 are round rods. When the roller frame 412 rotates, when the longitudinal ribs 101 rotate with the roller frame 412 to the lower position, the longitudinal ribs 101 will fall along the dividing rib rods 413 under the action of gravity. The limiting rib 4111 can support the falling longitudinal ribs 101 to limit the lowest position of the longitudinal ribs 101, so that when the roller frame 412 drives the dividing rib rods 413 to rotate and rise, the dividing rib rods 413 can drive the longitudinal ribs 101 to rotate and rise again, thereby realizing the rotation control of the longitudinal ribs 101. The central angle between multiple reinforcing bars 413 is related to the number and distribution of longitudinal bars 101 required for the reinforcing cage 100. Multiple longitudinal bars 101 can be selectively inserted into the gap between any two reinforcing bars 413.

[0067] In some embodiments, the limiting rib 4111 is arranged in an arc shape below the roller frame 412, and the radial length of the dividing rib 413 is not less than the arc radius of the limiting rib 4111.

[0068] For example Figure 4 The arc-shaped reinforcing bar of the limiting rib 4111 is coaxially arranged with the roller frame 412. The two arc-shaped reinforcing bars are spaced apart along the axial direction of the connecting shaft 43. When the dividing rib 413 rotates to the lower position, it passes through the gap between the two arc-shaped reinforcing bars to ensure that the longitudinal rib 101 is completely rotated. Preferably, the length of the dividing rib 413 satisfies the following condition: when the dividing rib 413 rotates to the lowermost position, the lowest position of the dividing rib 413 is lower than the lowest position of the limiting rib 4111.

[0069] In some embodiments, the reinforcement device 4 further includes a second reinforcement frame 42, which includes a first reinforcement frame 41, an arc-shaped roller conveyor 421, and a plurality of first rollers 422. The first rollers 422 are rotatably disposed at the ends of a plurality of reinforcing bars 413 and are evenly distributed at intervals. The arc-shaped roller conveyor 421 is disposed on the base frame 411 and located below the roller frame 412. When the roller frame 412 rotates, the first rollers 422 can roll along the arc-shaped roller conveyor 421 to support the roller frame 412.

[0070] It should be noted that, in order to simplify the design process, the second reinforcement frame 42, based on the first reinforcement frame 41, directly adds an arc-shaped roller conveyor 421 and multiple first rollers 422. For example... Figure 5 and Figure 8 Multiple reinforcing bars 413 are evenly spaced along the circumference of the roller frame 412, and multiple first rollers 422 are evenly spaced along the circumference of the reinforcing bars 413. Preferably, the number of first rollers 422 is less than the number of reinforcing bars 413. The axis of the first rollers 422 is parallel to the connecting shaft 43. The arc-shaped roller track 421 is an arc-shaped plate mounted on the base frame 411. The arc-shaped roller track 421 is coaxially mounted with the roller frame 412. When the roller frame 412 rotates, at least one first roller 422 can roll on the arc-shaped roller track 421 to support the roller frame 412, reducing the force on the connecting shaft 43 and improving the coaxiality of the multiple first reinforcing bars 41 and second reinforcing bars 42. The rollers and reinforcing bars 413 are rotatably mounted via U-shaped frames 423. Preferably, bearings can be used for mounting to reduce rotational friction.

[0071] In some embodiments, multiple first reinforcement frames 41 and multiple second reinforcement frames 42 are provided. Multiple first reinforcement frames 41 and multiple second reinforcement frames 42 are alternately arranged along the axial direction of the fixed turntable 2. Multiple first reinforcement frames 41 and multiple second reinforcement frames 42 share a connecting shaft 43.

[0072] like Figure 1As shown, multiple first reinforcement frames 41 and multiple second reinforcement frames 42 can share a base frame 411, or use a base frame 411 with the same structure. Multiple first reinforcement frames 41 and multiple second reinforcement frames 42 share a connecting shaft 43, or multiple connecting shafts 43 are coaxially connected via bearings to achieve coaxial rotation control. In this embodiment, the reinforcement device 4 includes two first reinforcement frames 41 and two second reinforcement frames 42 arranged alternately on the base frame 411. To improve the horizontal rotational stability of the connecting shaft 43, in some embodiments, a support bearing can be provided on the base frame 411 furthest from the fixed turntable 2 to support the connecting shaft 43. Of course, support bearings can be added to the base frames 411 of the first reinforcement frames 41 and the second reinforcement frames 42 according to distance and levelness requirements to support the connecting shaft 43 at multiple points of rotation.

[0073] In some embodiments, the roller frame 412 is provided with a support ring 4121, which is located at the root of a plurality of reinforcing bars 413 and can support the longitudinal ribs 101. The surfaces of the support ring 4121 and the first roller 422 are both provided with a shock-absorbing layer 424.

[0074] like Figure 8 As shown, a damping layer 424, such as a polyurethane layer, is provided on the outer surface of the first roller 422. This enhances the wear resistance of the surface of the first roller 422, and the damping layer 424 helps reduce noise and ensure production stability. Figure 4 and Figure 5 As shown, a support ring 4121 is provided on the roller frame 412 around the connecting shaft 43. The support ring 4121 is coaxially arranged with the connecting shaft 43. When the roller frame 412 rotates, the support ring 4121 also rotates. The support ring 4121 is assembled and fixed on the roller frame 412. The support ring 4121 is located on one side of multiple reinforcing bars 413. When the longitudinal reinforcing bar 101 passes through the gap between any two reinforcing bars 413, the longitudinal reinforcing bar 101 can be supported on the support ring 4121. Therefore, the support ring 4121 can be detachably connected to the roller frame 412 to facilitate the replacement of the support ring 4121 with a corresponding outer diameter according to the cage diameter of the reinforcing cage 100. The surface of the support ring 4121 is also provided with a shock-absorbing layer 424, such as a polyurethane material layer, which helps to reduce friction and noise between the longitudinal reinforcing bar 101 and the support ring 4121.

[0075] In some embodiments, the automatic steel cage production equipment further includes a wire feeding device 5, a straightening device 6, a welding device 7, and a cage support device 8. The wire feeding device 5 is located on one side of the bottom beam 1 to provide stirrups 102. The straightening device 6 is located on the fixed turntable 2 and is used to straighten the stirrups 102 provided by the wire feeding device 5. The welding device 7 is used to weld the straightened stirrups 102 onto the longitudinal reinforcement 101. The welding device 7 includes a pressure roller 71, which can press the stirrups 102 onto the longitudinal reinforcement 101 and press them against the arc-shaped support section 22. Multiple cage support devices 8 are provided, and the multiple cage support devices 8 are spaced apart on the bottom beam 1 along the length direction of the bottom beam 1. When the moving turntable 3 drives the steel cage 100 to move, the multiple cage support devices 8 rise in sequence to support the steel cage 100.

[0076] like Figure 1 and Figure 2 As shown, in this embodiment, to achieve automated production of the reinforcing cage 100, the longitudinal bars 101 are fed through the reinforcement device 4, and the stirrups 102 are provided as coiled steel bars through the wire feeding device 5. The coiled steel bars are first straightened by the straightening device 6 and then fed onto the longitudinal bars 101. One end of the stirrup 102 is then fixed to a longitudinal bar 101 by the welding device 7, and then the subsequent automated forming of the reinforcing cage 100 can be achieved. Both the welding device 7 and the straightening device 6 are fixed on the base frame 411 of the fixed turntable 2. The welding device 7 includes a replaceable pressure roller 71, which can be replaced according to the diameter of the stirrup 102. The straightening device 6 straightens the stirrups using a straightening roller 61, the specifications of which can be replaced according to the diameter of the stirrup 102. By selecting the corresponding specifications of the pressure roller 71 and the straightening roller 61, automated production of the reinforcing cage 100 with a maximum coiled steel bar (i.e., stirrup 102) diameter of 16mm can be achieved. It is understandable that for a steel cage 100 with a diameter of approximately 200mm, the diameter of the longitudinal reinforcement 101 is also relatively small, making it prone to deformation during welding. The arc-shaped support section 22 in this embodiment solves the problem of deformation of the steel cage 100 during the welding process, particularly when the stirrups 102 wrap around the longitudinal reinforcement 101, thereby improving the quality of the finished product. In some embodiments, the connecting shaft 43 between the reinforcement device 4 and the fixed turntable 2 is appropriately selected based on the diameter of the steel cage 100, as long as it meets the strength requirements. The cage support device 8 is as follows... Figure 1As shown, multiple cage support devices 8 are spaced apart on the bottom beam 1 and can rotate and rise. When the cage support device 8 rotates and lowers, the movable turntable 3 can drive the longitudinal reinforcement 101 to move past the cage support device 8. Then, the cage support device 8 rotates and rises to support the steel cage 100. In this process, multiple cage support devices 8 rotate and support the steel cage 100 between the fixed turntable 2 and the movable turntable 3 in sequence. The cage support device 8 includes a support rod rotatably connected to the bottom beam 1 and a pair of second rollers rotatably disposed on the top of the support rod. The rotation axis of the support rod is perpendicular to the length direction of the bottom beam 1. The two second rollers are spaced apart on the top of the support rod along the rotation axis of the support rod. The rotation axes of the two second rollers are parallel to each other and parallel to the longitudinal reinforcement 101. When the steel cage 100 or the longitudinal reinforcement 101 rotates, the second rollers roll accordingly to support the steel cage 100.

[0077] The automatic steel cage production equipment provided by this utility model can perform the automatic production of 100 steel cages through the following steps:

[0078] According to the specifications of the longitudinal bars 101 and stirrups 102 of the steel cage 100, the welding device 7 and the straightening device 6 are respectively equipped with pressure rollers 71 and straightening rollers 61 of appropriate specifications. The movable turntable 3 and the disc 33 of the fixed turntable 2 are fixedly installed with a certain number of second through-bar pipes 332 and first through-bar pipes 21 according to the specifications of the steel cage 100. The cage support device 8 rotates and lowers to the surface of the first bottom beam 1.

[0079] The rotation of the fixed turntable 2 drives the first reinforcement frame 41 and / or the second reinforcement frame 42 of the reinforcement device 4 to rotate, thereby distributing multiple raw material longitudinal reinforcements 101 at intervals between the reinforcement bars 413.

[0080] Multiple longitudinal ribs 101 are sequentially threaded through the first through pipe 21 and the second through pipe 332 at the positions of the disk 33 of the fixed turntable 2 and the movable turntable 3, and the ends of the longitudinal ribs 101 at the movable turntable 3 are locked to the second through pipe 332 with bolts.

[0081] Then, place the coiled steel bar on the wire laying device 5, and pass the end of the coiled steel bar through the straightening wheel 61 of the straightening device 6. Adjust the spacing between the straightening wheels 61 to straighten the coiled steel bar, and pull the coiled steel bar to the position of the longitudinal bar 101 of the arc support section 22. Manually weld the end of the coiled steel bar (i.e., the stirrup 102) to the longitudinal bar 101 for fixation.

[0082] Then adjust the automatic welding device 7. After the adjustment is completed, start the automatic program. Move the turntable 3 to drive the steel cage 100 to move away from the fixed turntable 2 along the bottom beam 1, realizing the automated production of the steel cage 100. During the production process, multiple cage support devices 8 rise in sequence to support the finished steel cage 100, thus completing the automated production of the steel cage 100.

[0083] After the steel cage 100 is produced, the locking bolts at the second through-tube 332 on the movable turntable 3 are loosened, and the movable turntable 3 is moved a distance further so that the longitudinal reinforcement 101 is disengaged from the second through-tube 332 on the movable turntable 3; the finished steel cage 100 is lifted away, and the cage support device 8 is rotated and retracted again. The automatic welding device 7 and the movable turntable 3 are reset to prepare for the production of the next steel cage 100.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
