Description

Technical Field

[0001] The utility model relates to the field of steel bar processing, in particular to an automatic steel bar cage frame forming device. Background Art

[0002] In the production process of cast-in-place pile reinforcement cage, improving the degree of automation of reinforcement cage processing equipment can not only save a lot of labor costs, but also greatly improve production efficiency and ensure processing quality, thereby achieving the goal of improving economic benefits.

[0003] At present, the cast-in-place pile reinforcement cage is formed by wrapping stirrups around the outer periphery of the reinforcement cage frame. Therefore, the forming of the reinforcement cage frame is the first step in the production of the reinforcement cage. However, there is no fully automated equipment for producing reinforcement cage frames at the construction site. The existing equipment is an automated reinforcement cage production equipment, which is widely used at many construction sites.

[0004] The equipment consists of a main shaft, a drive unit, a retractable reinforcement ring bracket and a main shaft tail support. One end of the main shaft is connected to the drive unit, and the other end is an open end. The drive unit can drive the rotating shaft to rotate. Since the retractable reinforcement ring bracket is fixed on the rotating shaft, the reinforcement ring bracket rotates with the main shaft when the main shaft rotates. The production is divided into three steps. 1. The reinforcement cage skeleton is formed. 2. The reinforcement winding is completed. 3. The main shaft is uncaged.

[0005] At the beginning of the first step, the operator first places all the reinforcement rings on the reinforcement ring bracket, and uses the stretchability of the reinforcement ring bracket to tighten the reinforcement ring on the reinforcement ring bracket. When the feeding device delivers the first main bar and presses the main bar and the reinforcement ring tightly, the welding gun installed on the feeding device automatically starts welding to firmly weld the main bar and the reinforcement ring. After that, the driving device drives the main shaft to rotate a certain angle. Since the reinforcement ring will rotate synchronously with the main shaft, the first main bar welded on the reinforcement ring also rotates the same angle. Thereafter, the same action is repeated until all the main bars and reinforcement rings are welded to form a steel cage skeleton. At the beginning of the second step, the end of the winding bar is first welded and fixed to any main bar at the required position. After that, the driving device drives the main shaft to rotate and then drives the steel cage skeleton to rotate together. At the same time, the winding machine starts to move linearly to the other end of the steel cage synchronously, and continuously provides winding bars to the steel cage skeleton during the movement. Since the direction of the winding bar is almost 90 degrees to the direction of the steel cage skeleton, the winding bar is tightly wrapped around the outside of the steel cage skeleton in a spiral shape. Moreover, when the rebar contacts each main bar, the follow-up welder can weld the rebar to the main bar until the rebar winding machine moves to the required position to complete the entire rebar winding action. After that, the follow-up welder melts the rebar by applying a large current to complete the rebar winding action. In the third step, the reinforcement ring support frame shrinks, and after the bracket is separated from the reinforcement ring, the support at the tail end of the spindle is reset, and the bottom bracket holds up the steel cage and moves toward the open end of the spindle until the steel cage and the spindle are completely separated. At this point, the production process of a steel cage is completed.

[0006] Although this type of equipment realizes the automation of steel cage production, it still has major defects. Specifically, it is reflected in the following aspects:

[0007] The length of the main shaft is too long. If a 18-meter-long steel cage is produced, the length of the main shaft will be nearly 20 meters, and the sagging will be serious.

[0008] Since the spindle needs to transmit a large torque, the spindle diameter is large and cannot process small diameter steel cages. The minimum diameter that can be processed by existing equipment is about 600mm.

[0009] Due to the serious sagging of the main shaft, when the steel cage and the main shaft are out of the cage, the reinforcing ring bracket and the reinforcing ring are very likely to come into contact, resulting in production accidents.

[0010] The forming of the steel cage skeleton and the winding of the steel bars are realized at the same station and cannot be carried out at the same time. Therefore, the production efficiency is low.

[0011] The components of the equipment are bulky and difficult to assemble and transport on site. Summary of the invention

[0012] According to the above technical problems, the utility model has developed a fully automated steel cage skeleton forming equipment. The utility model can solve the automatic feeding of main bars, automatic welding of main bars and reinforcing rings, and automatic rotation of reinforcing rings at a fixed angle in the process of steel cage production, greatly improving the production efficiency. It not only effectively guarantees the processing quality of steel cage production, but also cooperates with fully automatic winding equipment to form a highly efficient automated steel cage production system.

[0013] An automated steel cage skeleton forming device is characterized by comprising a working module, a positioning structure, and a control structure, wherein the positioning structure is connected to the working module, and the working module is connected to the control structure.

[0014] The positioning structure comprises a base and a positioning beam, and the positioning beam is fixed on the upper side of the base.

[0015] The positioning beam is a positioning steel beam.

[0016] The working module comprises a chassis, a rotating unit and a rotating unit, and the rotating unit and the rotating unit are respectively installed on the chassis;

[0017] The rotating unit comprises a chuck assembly and a tray assembly. There are two chuck assemblies, and a tray assembly is arranged between the two chuck assemblies.

[0018] It also includes a control structure, the working module is connected to the control structure; the control structure is composed of a display screen and a control unit, the control unit is connected to the display screen and the working module, and the control structure is an existing controller.

[0019] The chuck assembly includes a reset spring, a rotating clamp, a clamping plate, a guide wheel, and a telescopic hydraulic cylinder. The clamping plate is provided with an arc groove. The three guide wheels on the rotating clamp are inserted into the arc groove of the clamping plate and are integrated with the clamping plate. The three guide wheels have the same virtual radius as the arc groove of the clamping plate and are concentric with the virtual center of the reinforcing ring, but have different radii. The rotating clamp is connected to the chassis through a telescopic hydraulic cylinder, and the rotating clamp is connected to the clamping plate through a reset spring. Fixed columns are provided on the rotating clamp and the clamping plate, and a reset spring is fixed on the fixed column.

[0020] The clamping surface of the clamping plate can exert a certain clamping force on the outer edge of the reinforcement ring. The arc-shaped long circular groove on it allows the three guide wheels on the rotating clamping plate to penetrate into it and tightly combine with it. Since the virtual radius of the three guide wheels is the same as that of the arc-shaped groove of the clamping plate, and they are concentric with the virtual center of the reinforcement ring, but the radius is different.

[0021] Therefore, when the support plate rotates, it will drive the reinforcing ring to rotate, and then drive the clamping plate to rotate together with the reinforcing ring, wherein the rotation of the support plate is active, while the rotation of the reinforcing ring and the clamping plate is passive. When the clamping plate is separated from the reinforcing ring, the clamping plate can be restored to its original position under the action of the reset spring. In addition, the telescopic hydraulic cylinder in the chuck assembly can control the rotation angle of the rotating clamp plate, and the reinforcing ring can be clamped when the telescopic rod is fully extended. When appropriately contracted, the clamping plate can be separated from the reinforcing ring. When fully contracted, the rotating clamp plate can be rotated 90 degrees to a horizontal position.

[0022] The reset tension springs on the left and right sides need to be installed in an up-and-down staggered manner, because when the clamping plate rotates with the steel cage, the force directions of the tension springs on the left and right sides are exactly opposite.

[0023] The tray assembly includes a lifting clamp, a support plate, guide wheels, a rotating motor, a gear plate, a linear guide rail, and a telescopic rod. The inner side surfaces of the two connecting rods on the chassis are connected to the lifting clamp through a linear guide rail pair. The lifting clamp is connected to the chassis through the telescopic rod. The three guide wheels on the lifting clamp are inserted into the arc groove of the support plate and combined with the support plate to form a whole. The lower end surface of the support plate is an arc-shaped toothed disc structure, which meshes with the toothed disc fixed on the end of the rotor of the rotating motor. When the hydraulic rod is extended, the lifting clamp rises.

[0024] When the hydraulic rod is retracted, the lifting splint descends. The combination of the lifting splint and the support plate is similar to that of the rotating splint and the clamping plate. The difference is that the lower end surface of the support plate is an arc-shaped toothed disc structure, which meshes with the small toothed disc fixed to the end of the rotating motor rotor. Since the rotating motor is fixed to the lifting splint, when the rotating motor rotates, the support plate will rotate relative to the lifting splint with the virtual center of the circle formed by the guide wheel as the axis, thereby driving the reinforcement ring to rotate. When the telescopic rod is retracted, the support plate is separated from the reinforcement ring. At this time, the rotating motor is reversed to reset the support plate, while the reinforcement ring does not rotate at this time.

[0025] The rotating unit includes a column, a rotating motor, a hydraulic claw, a welding gun, a welding gun fixing part, and a rotating arm; the column is installed on the chassis, the rotating motor is installed on the upper side of the column, the output shaft of the rotating motor is connected to the rotating arm, the welding gun fixing part and the hydraulic claw are installed at the front end of the rotating arm, and the welding gun is fixed on the welding gun fixing part.

[0026] The chuck assembly adopts a clamping device with a lattice structure.

[0027] The telescopic rod is a hydraulic telescopic rod, a pneumatic telescopic rod or an electric push rod.

[0028] The rotating arm is cleverly driven by a rotating motor and can achieve precise flipping of about 180 degrees. When rotating clockwise to a horizontal position, the hydraulic claw at the front end of the rotating arm can accurately grab the main reinforcement sent by the feeding device. Then, by rotating 180 degrees counterclockwise, the grabbed main reinforcement is accurately sent to the top of the reinforcement ring and pressed tightly against the reinforcement ring. At this time, the welding gun installed at the front end of the rotating arm automatically starts and starts welding, firmly welding the main reinforcement and the reinforcement ring together.

[0029] The control unit controls and connects the telescopic hydraulic cylinder, the rotating motor, the telescopic rod, the rotating motor, the hydraulic claw, and the welding gun.

[0030] The upper sides of the clamping plate and the supporting plate are both provided with grooves.

[0031] The chassis comprises a fixed plate and a connecting rod, the fixed plate is fixed with a connecting rod and a column, the connecting rod is connected to a tray assembly, and the column is connected to a rotating unit.

[0032] The support plate can be rotated at a certain angle by using a hydraulic lever to drive the rack to move linearly, and the rack can be meshed with the gear part of the support plate to achieve the purpose of rotating the support plate at a certain angle.

[0033] When the utility model is used, since the reinforcing ring is tightly clamped by the support plate and the two clamping plates, and the virtual axis of the reinforcing ring, the support plate and the two clamping plates are the same, when the rotating motor drives the support plate to rotate through the engagement of the small gear plate with the gear edge of the support plate, the two clamping plates together with the reinforcing ring will rotate with the support plate at the same virtual axis, and the size of the rotation angle is controlled by the rotating motor. Therefore, the fixed-angle rotation of the reinforcing ring without an axis can be realized.

[0034] The beneficial effects of the utility model are as follows: the utility model has a simple structure, low cost, is easy to assemble and transport on site, and is suitable for wide promotion and use. The design of the utility model aims to improve the production efficiency of the steel cage frame while giving it great flexibility in size. Through the carefully designed chuck assembly and tray assembly, as well as the flexible working module, the utility model can not only meet the requirements for efficiency and precision in industrial production, but also adapt to the ever-changing market demand, providing an efficient and reliable solution for the production of steel cage frames.

[0035] The chuck assembly and tray assembly of the rotating unit in the working module of the utility model are detachable structures. By changing the sizes of the rotating clamping plate and the clamping pressure plate as well as the lifting clamping plate and the support plate, steel cage frames of any size can be processed and produced, realizing automated production equipment that can be used for both small diameter (200mm diameter) and extra-long length steel cages.

[0036] The equipment of the present application is used in conjunction with the automated rib winding equipment, and the two processes of frame forming and rib winding can be performed simultaneously, which can greatly improve production efficiency.

[0037] This application uses a rotating arm for welding, without the need for manual welding, and the processing quality is stable and reliable without any safety hazards.

[0038] The present application adopts a spindle-free design, which avoids the use of an extra-long spindle and avoids the occurrence of spindle sagging. The present application is used through working modules. There are multiple working modules, which can be determined according to actual conditions. The working modules are detachable structures, which can realize modular production and greatly reduce production costs.

[0039] The clamping plate and the supporting plate of the utility model are both provided with grooves on the upper sides, and the main reinforcement is fixed in the grooves when in use. The grooves form a main reinforcement avoidance gap, ensuring that the positioning error is small in the whole process of forming the steel cage skeleton. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The utility model is an automated steel cage frame forming machine, the core of which is composed of three major components: a positioning structure, a working module and a control unit. Among them, the design of the working module is extremely flexible and allows unlimited expansion, so that the machine can produce super-long steel cage frames. Each working module is composed of a chassis, a rotating unit and a rotating unit, and is equipped with a rotating motor, which can achieve 180-degree precise flipping and has an automatic welding function.

[0054] The rotating unit consists of two main parts: the chuck assembly and the tray assembly. The chuck assembly contains precision components such as the reset tension spring, the rotating splint, the clamping plate, the guide wheel and the telescopic hydraulic cylinder, which can apply a stable clamping force to the reinforcement ring. The arc-shaped long circular groove on it allows the three guide wheels on the rotating splint to fit perfectly with it to form a solid whole. This design ensures that when the pallet rotates, the reinforcement ring can be smoothly driven, and the clamping plate will rotate with the reinforcement ring, achieving perfect coordination between active and passive. When the clamping plate is separated from the reinforcement ring, the clamping plate can quickly return to its original position under the action of the reset tension spring. In addition, the addition of the telescopic hydraulic cylinder makes the angle control of the rotating splint more precise. When fully extended, it can clamp the reinforcement ring, and when appropriately retracted, the clamping plate can be separated from the reinforcement ring. When fully retracted, the rotating splint can smoothly turn to a horizontal position.

[0055] The tray assembly is composed of a lifting splint, a support plate, a guide wheel, a rotating motor, a gear plate, a linear guide rail, and a lifting hydraulic cylinder. The inner side surfaces of the two columns on the chassis are connected to the lifting splint through a linear guide pair, and the lifting splint is connected to the chassis through a telescopic rod. When the telescopic rod is extended, the lifting splint rises; when the telescopic rod is retracted, the lifting splint descends. The combination of the lifting splint and the support plate is similar to that of the rotating splint and the clamping plate, but the lower end surface of the support plate adopts a unique arc-shaped toothed disc structure, which meshes with the small toothed disc fixed to the end of the rotating motor rotor. Since the rotating motor is fixed to the lifting splint, when the rotating motor rotates, the support plate will rotate relative to the lifting splint with the virtual center of the circle formed by the guide wheel as the axis, thereby driving the reinforcing ring to rotate. When the telescopic rod is retracted, the support plate is separated from the reinforcing ring, and the rotating motor is reversed at this time, which can reset the support plate, while the reinforcing ring does not rotate at this time.

[0056] The rotating unit, the core component of this machine, is composed of precision components such as the column, rotating motor, hydraulic claw, welding gun, welding gun fixture and rotating arm. The column is firmly embedded on the chassis, and the rotating motor is cleverly installed on its upper end. The output shaft of the rotating motor is connected to the rotating arm to form a smooth motion chain. The front end of the rotating arm is fixed with a welding gun fixture and hydraulic claw. The welding gun fixture firmly fixes the welding gun to form a complete welding operation unit.

[0057] The ingenious design of the rotating arm enables it to be driven by a rotating motor to achieve a precise flip of about 180 degrees. When it rotates clockwise to a horizontal position, the hydraulic claw at the front end of the rotating arm can accurately grab the main reinforcement sent by the feeding device. Then, by rotating 180 degrees counterclockwise, the grabbed main reinforcement is accurately sent to the top of the reinforcement ring and pressed tightly against the reinforcement ring. At this time, the welding gun installed at the front end of the rotating arm automatically starts and starts welding, firmly welding the main reinforcement and the reinforcement ring together. This series of actions is completed.

[0058] The telescopic rod can be a hydraulic telescopic rod, a pneumatic telescopic rod or an electric push rod.

[0059] When the equipment is in use, when the steel cage rotates clockwise, the reset spring is installed at the lower left and upper right. When the steel cage rotates counterclockwise, the reset spring is installed at the upper left and lower right. Example 2

[0060] The utility model is an automated steel cage frame forming machine, the core of which is composed of three major components: a positioning structure, a working module and a control unit. Among them, the design of the working module is extremely flexible and allows unlimited expansion, so that the machine can produce super-long steel cage frames.

When fully extended, it can clamp the reinforcement ring, and when appropriately retracted, the clamping plate can be separated from the reinforcement ring. When fully retracted, the rotating splint can smoothly turn to a horizontal position.

[0062] The tray assembly is composed of a lifting splint, a support plate, a guide wheel, a rotating motor, a gear plate, a linear guide rail, and a lifting hydraulic cylinder. The inner side surfaces of the two columns on the chassis are connected to the lifting splint through a linear guide pair, and the lifting splint is connected to the chassis through a gear transmission structure. When the gear transmission structure is extended, the lifting splint rises; when the gear transmission structure is retracted, the lifting splint descends. The combination of the lifting splint and the support plate is similar to that of the rotating splint and the clamping plate, but the lower end surface of the support plate adopts a unique arc-shaped toothed disc structure, which meshes with the small toothed disc fixed to the end of the rotating motor rotor.

At this time, the welding gun installed at the front end of the rotating arm automatically starts and starts welding, firmly welding the main reinforcement and the reinforcement ring together. This series of actions is completed. The gear transmission structure realizes the extension and contraction of the rack through the meshing of the gear and the rack to achieve the same function as the hydraulic telescopic rod. Example 3

[0065] The utility model is an automated steel cage frame forming machine, the core of which is composed of three major components: a positioning structure, a working module and a control unit. Among them, the design of the working module is extremely flexible and allows unlimited expansion, so that the machine can produce super-long steel cage frames. Each working module is composed of a chassis, a rotating unit and a rotating unit, and is equipped with a rotating motor, which can achieve 180-degree precise flipping and has an automatic welding function.

[0066] The rotating unit consists of two main parts: the chuck assembly and the tray assembly. The chuck assembly contains precision components such as the reset tension spring, the rotating splint, the clamping plate, the guide wheel and the telescopic hydraulic cylinder, which can apply a stable clamping force to the reinforcement ring.

When fully extended, it can clamp the reinforcement ring, and when appropriately retracted, the clamping plate can be separated from the reinforcement ring. When fully retracted, the rotating splint can smoothly turn to a horizontal position.

[0067] The tray assembly is composed of lifting and lowering splints, supporting plates, guide wheels, rotating motors, gear plates, linear guides and lifting hydraulic cylinders. The inner sides of the two columns on the chassis are connected to the lifting and lowering splints through linear guide pairs, and the lifting and lowering splints are connected to the chassis through the motor transmission structure. When the motor transmission structure is extended, the lifting and lowering splints rise; when the motor transmission structure is retracted, the lifting and lowering splints fall. The combination of the lifting and lowering splints and the supporting plates is similar to that of the rotating splints and the clamping plate, but the lower end surface of the supporting plate adopts a unique arc-shaped toothed disc structure, which meshes with the small toothed disc fixed on the end of the rotating motor rotor. Since the rotating motor is fixed on the lifting and lowering splints, when the rotating motor rotates, the supporting plate will rotate relative to the lifting and lowering splints with the virtual center of the circle formed by the guide wheel as the axis, thereby driving the reinforcing ring to rotate. When the motor transmission structure is retracted, the supporting plate is separated from the reinforcing ring, and the rotating motor is reversed at this time, which can reset the supporting plate, while the reinforcing ring does not rotate at this time. The motor transmission structure uses the motor to drive the rope reel to operate, and the combination with the spring achieves the same function as the hydraulic telescopic rod.

[0068] The rotating unit, the core component of this machine, is composed of precision components such as the column, rotating motor, hydraulic claw, welding gun, welding gun fixture and rotating arm. The column is firmly embedded on the chassis, and the rotating motor is cleverly installed on its upper end. The output shaft of the rotating motor is connected to the rotating arm to form a smooth motion chain. The front end of the rotating arm is fixed with a welding gun fixture and hydraulic claw. The welding gun fixture firmly fixes the welding gun to form a complete welding operation unit.

[0069] The ingenious design of the rotating arm enables it to be driven by a rotating motor to achieve a precise flip of about 180 degrees.

At this time, the welding gun installed at the front end of the rotating arm automatically starts and starts welding, firmly welding the main reinforcement and the reinforcement ring together. This series of actions is completed. Example 4

[0070] When producing and processing the steel cage keel, the operator first places the reinforcement ring in the chuck assembly of the working module, and then acts on the rotating clamp through the telescopic hydraulic cylinder, and the clamping plate clamps the reinforcement ring. After the hydraulic claw on the rotating arm grabs the first main bar sent by the feeding device, the rotating arm is driven by the rotating motor to rotate upward 180 degrees and then the main bar is sent to the top of the reinforcement ring and pressed against the reinforcement ring. At this time, the welding gun installed on the rotating arm automatically starts welding, and the main bar and the reinforcement ring are welded firmly. After that, the control unit of the control structure issues an instruction, and the rotating motor rotates and drives the reinforcement ring to rotate to the specified angle. After that, the support plate is reset first without releasing the clamping plate, and the clamping plate reset action is started after the support plate reset action is completed. In order to ensure that the state of the reinforcement ring does not change during the reset action, the reset of the support plate and the clamping plate can be carried out in the form of 1, 3, 5..., 2, 4, 6... groups. After all the reset actions are completed, the welding procedure of the second main bar begins. This cycle repeats the same action until all the main bars and reinforcement rings are welded together to form a steel cage skeleton.

[0071] When the forming operation of the steel cage skeleton is completed, the rotating clamps on both sides of the steel cage skeleton rotate 90 degrees, and the steel cage skeleton is no longer subject to any constraints. At this time, other transportation tools can be used to move the steel cage skeleton out of the skeleton forming station and transport it to the next process.
