Description

Technical Field

[0001] The invention relates to the technical field of steel cage production, and in particular to a steel cage forming device. Background Art

[0002] The main role of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body so that it can withstand a certain axial tension. The welding of the steel cage includes two types: one-piece welding and combined welding. The one-piece welding includes two turntables. The two turntables are used to fix several circularly arranged longitudinal bars. In the process of the two turntables driving the longitudinal bars to rotate, the traction machine drives the bundled bars to be evenly wrapped around the longitudinal bars. While winding, they are welded by electric welding. In the construction foundation engineering, based on the geomechanical characteristics and structural bearing capacity requirements, the steel cage adopts a conical or annular (circular) cross-section design. The conical steel cage needs to be reduced in diameter during production.

The application has a reasonable structure, which realizes the insertion of the main bars of the steel cage into the interior of the placement slot one by one, and then fixes the main bars by the clamping block. Then, when rotation is required during the welding process, the first toothed disc is rotated to rotate the mounting ring as a whole, thereby facilitating the welding of the steel cage.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] like Figures 1 to 9As shown, the present invention provides a steel cage forming device, comprising: a welding frame 1, and along the feeding direction of the welding frame 1, there are arranged in sequence: a traction component 3 for pulling the longitudinal reinforcement, a fixed plate 2 for supporting the longitudinal reinforcement, and a support component 4; the welding frame 1 is also provided with: a welding mechanism for welding the steel cage, the welding mechanism welds the longitudinal reinforcement and the stirrups through a mobile resistance welding gun, the stirrup feeding device winds the stirrups around the longitudinal reinforcement through a wire rod pay-off frame and a simple straightening wheel, and the cooling system dissipates heat at the welding position through an air-cooling fan.

[0036] During use, the longitudinal reinforcement is loaded by the robot to the support assembly 4, the support assembly 4 aligns the ends of the longitudinal reinforcement, and then feeds the reinforcement to the traction assembly 3 and the fixed disk 2. After the feeding is completed, the longitudinal reinforcement is driven to move by the traction assembly 3. At this time, the stirrup feeding device wraps the stirrups around the longitudinal reinforcement through the wire rod pay-off frame and the simple straightening wheel. At the same time, the welding mechanism welds the joints between the longitudinal reinforcement and the stirrups to complete the forming process of the steel cage.

[0037] Specifically, the traction assembly 3 includes: a traction disc 31, a ring gear 32 fixedly mounted on the traction disc 31, a gear 33 engaged with the ring gear 32, a power source 1 34 fixedly mounted on the gear 33, the power source 1 34 fixedly mounted on the welding frame 1, the traction disc 31 is rotatably mounted on the fixed frame, the fixed frame is slidably connected to the welding frame 1, and a linear moving module for driving the fixed frame to move is installed on the welding frame 1. The linear moving module can be optionally a cylinder or a hydraulic cylinder. When in use, the fixed frame is driven to move on the welding frame 1 by the linear moving module, and at the same time, the power source 2 363 is started to drive the ring gear 32 to rotate through the gear 33, and at the same time, the traction disc 31 is rotated, so that the traction disc 31 can rotate while moving linearly on the welding frame 1, and at the same time cooperate with the welding mechanism and the stirrup feeding device to realize the forming processing of the steel cage.

[0038] It should be noted that the size and shape of the steel cage need to be adjusted according to actual needs. Therefore, a guide groove 35 is provided on the traction disc 31, and a fixing piece 36 for fixing the longitudinal reinforcement is provided on the guide groove 35; there are multiple groups of guide grooves 35, and the fixing piece 36 is adjusted on the traction disc 31 through the guide groove 35 to adjust the longitudinal reinforcement, thereby adjusting the size of the steel cage. It should be noted that a guide groove 35 is also provided on the fixed disc 2, and a fixing piece 36 is provided. When in use, the traction disc fixing piece and the fixed disc fixing piece cooperate with each other to ensure the stability of the longitudinal reinforcement after adjustment, and can also realize the production of conical steel cage.

[0039] In detail, the fixing member 36 is composed of: an adjusting frame 361 slidably mounted on the guide groove 35, a screw 362 threadedly connected to the adjusting frame 361, the screw 362 is a single-line screw, one end of the screw 362 is rotatably mounted on the traction disk 31, a power source 363 fixedly mounted on one end of the screw 362, the power source 363 is preferably a driving motor, the power source 363 is fixedly mounted on the traction disk 31, a guide rod 364 slidably mounted on the adjusting frame 361, the guide rod 364 is fixedly mounted on the traction disk 31, a support block 365 fixedly mounted on the adjusting frame 361, a rotating rod 367 threadedly mounted on the adjusting frame 361, an upper clamping block 368 and a lower clamping block 366 for clamping and fixing the longitudinal reinforcement from the top and bottom respectively.

[0040] First, the longitudinal reinforcement passes between the upper clamping block 368 and the lower clamping block 366, and then the rotating rod 367 is rotated. The rotating rod 367 is a single-line screw so that the upper clamping block 368 is guided by the adjusting frame 361 and moves closer to the lower clamping block 366, and cooperates with the lower clamping block 366 to fix the longitudinal reinforcement. When the diameter of the steel cage needs to be adjusted, the power source 2 363 is started to drive the screw 1 362 to rotate, and then drive the adjusting frame 361 to move along the axis of the guide rod 364 to adjust the distance of the adjusting frame 361. The rotating rod 367 can be rotated manually or driven by a motor.

[0041] The fixing plate 2 and the pulling plate 31 are connected through the fixing piece 36 to realize the independent adjustment of the longitudinal reinforcement radial direction and the independent controllable position of each longitudinal reinforcement. When manufacturing cages with complex geometric shapes, conical pile cages with gradually changing diameters and segmented variable diameter cages such as bottom enlarged heads can be continuously produced in one clamping, achieving better processing.

[0042] It should be noted that when producing the conical steel cage, due to the different diameters of the steel cages on the traction disk 31 and the fixed disk 2, the arc rotation center of the clamp in the diameter-changing production process does not coincide with the axis of the longitudinal reinforcement. When directly fixing through the upper clamping block 368 and the lower clamping block 366, additional torque is generated, which affects the welding and forming of the steel cage. Therefore, a second rotating shaft 3681 is fixedly installed on the upper clamping block 368, and the second rotating shaft 3681 is rotatably connected to the rotating rod 367. A first rotating shaft 3661 is fixedly installed on the lower clamping block 366, and the first rotating shaft 3661 is rotatably connected to the support block 365.

[0043] The axial direction of the rotating shaft 1 3661 and the rotating shaft 2 3681 is the same as the axial direction of the longitudinal reinforcement, so that the angle of the upper clamping block 368 and the lower clamping block 366 can be adjusted. When the axis of the longitudinal reinforcement changes, the upper clamping block 368 and the lower clamping block 366 are adjusted synchronously to ensure the clamping effect of the longitudinal reinforcement.

[0044] In addition, the longitudinal reinforcement is loaded by a robot, and it is difficult to ensure the accuracy of the ends of each longitudinal reinforcement, resulting in structural instability after the steel cage is produced, which affects the finished product effect of the steel cage. The support component 4 includes: a support frame 1 41 and a support frame 2 42 for supporting the longitudinal reinforcement; a driving component 43 for driving the support frame 1 41 and the support frame 2 42 to move. The longitudinal reinforcement is placed on the support frame 1 41 and the support frame 2 42 by a robot, and then the support frame 1 41 and the support frame 2 42 are driven to move by the driving component 43 to align the ends of the longitudinal reinforcement and load the longitudinal reinforcement to the fixed disk 2 and the traction disk 31 to achieve accurate loading.

[0045] Specifically, the driving assembly 43 includes: a power source three 431 fixedly mounted on the welding frame 1, a screw two 432 fixedly mounted on the output shaft of the power source three 431, an adjusting frame 433 threadedly connected to the screw two 432, and the support frame one 41 and the support frame two 42 are rotatably mounted on the adjusting frame 433. The power source three 431 is preferably a driving motor, and the screw two 432 is provided with two groups of spiral lines with opposite rotation directions. The support frame one 41 and the support frame two 42 are respectively mounted on the two groups of spiral lines. When in use, the power source three 431 is started to drive the screw two 432 to rotate, so that the two groups of adjusting frames 433 drive the support frame one 41 and the support frame two 42 to move closer to or away from each other. In addition, the adjusting frame 433 can drive the support frame one 41 and the support frame two 42 to rotate, and the rotational movement mechanism is the same as the above-mentioned driving the traction disk 31 to rotate.

[0046] A spring 421 is fixed on the support frame 2, and a top plate 422 is fixed on the spring 421. The support frame 1 41 is also provided with a spring 421 and a top plate 422. The surfaces of the support frame 1 41 and the support frame 2 42 are provided with multiple sets of tooth grooves, and the spring 421 and the top plate 422 are both installed in the tooth grooves, and an automatic clamp for clamping the longitudinal reinforcement is installed in the tooth grooves. The longitudinal reinforcement is placed on the top plate 422 by a manipulator. At this time, the spring 421 can absorb the impact when the longitudinal reinforcement is placed to avoid damage to the support frame 1 41 and the support frame 2 42. Then the automatic clamp fixes the longitudinal reinforcement, initially realizing the loading of the manipulator and completing the preparation work for aligning the ends of the longitudinal reinforcement.

[0047] The support frame 1 41 is fixed with a fixing sleeve 411, the fixing sleeve 411 is fixedly installed with a fixing frame 412, the fixing frame 412 is provided with an air guide groove 413, the air guide groove 413 is slidably installed with a baffle 414, the support frame 2 42 is fixedly installed with a fixing rod 425, the fixing rod 425 is fixedly installed with a movable plate 426, the movable plate 426 is slidably connected with the fixing sleeve 411, first, after the automatic clamp fixes the longitudinal reinforcement, the power source 3 431 is started to drive the screw 2 432 to rotate, the support frame 1 41 and the support frame 2 42 are connected. The two support frames 41 and 42 are moved away from each other, so that the longitudinal reinforcement is moved away from the support frame 1 41. Then, the power source 3 431 controls the screw 2 432 to reverse, so that the support frame 1 41 and the support frame 2 42 are close to each other. At this time, the support frame 2 42 drives the movable plate 426 to slide in the fixed sleeve 411 through the fixed rod 425, and squeezes the gas in the fixed sleeve 411 into the interior of the fixed frame 412, so that the gas pushes the baffle 414 to move through the air guide groove 413, and the baffle 414 extends from the fixed frame 412. Then, the end of the longitudinal reinforcement abuts against the baffle 414, so that the ends of the multiple groups of longitudinal reinforcements are aligned, and the use effect is good. Figure 9 As shown, the surface of the automatic clamp is equipped with balls, which allows the longitudinal reinforcement to move axially.

[0048] Before loading the longitudinal reinforcement, the distance between the support frame 1 41 and the support frame 2 42 can be adjusted to ensure the support effect of the longitudinal reinforcement and prevent the longitudinal reinforcement from being offset and falling after being placed on the top plate 422.

[0049] Finally, it should be added that a sac 423 is fixedly installed on the support frame 2 42, and the air pipe 424 is connected to the fixed sleeve 411. The sac 423 is connected with the air pipe 424. When the support frame 1 41 and the support frame 2 42 move away from each other, the support frame 2 42 drives the movable plate 426 to move in the fixed sleeve 411 through the fixed rod 425, and sends the gas in the fixed sleeve 411 into the sac 423 through the air pipe 424, so that the sac 423 expands. It is suitable for the production of steel cages or conical steel cages with smaller diameters that cannot be supported at the end by the support frame 2 42, and the end support of the smaller diameter is used to avoid shaking during the production process of the steel cage, which affects the welding effect of the steel cage.

[0050] Specifically, after the longitudinal reinforcement is fixed by the fixing member 36, the second support frame 42 is controlled to be away from the longitudinal reinforcement, and then the diameter of the steel cage is adjusted by the fixing member 36, and then the second support frame 42 is controlled to be close to the end of the longitudinal reinforcement. Due to the flexibility of the sac 423, the sac 423 can clamp the longitudinal reinforcement after contacting the longitudinal reinforcement, thereby avoiding shaking of the end of the longitudinal reinforcement.

[0051] That is to say, when support frame 1 41 and support frame 2 42 move, on the one hand, they can drive the longitudinal reinforcement to move and move the baffle 414 out, so as to align the ends of the longitudinal reinforcement; on the other hand, they can support the ends of the longitudinal reinforcement and adapt to the end support during the production of the conical steel cage, with good practical effect.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
