Description

Technical Field

[0001] The present invention relates to the technical field of production of steel reinforcement cages, and particularly relates to a steel reinforcement cage production device for spreading hoop bars. Background Art

[0002] Steel reinforcement cages are mainly made of steel bars, which are typical metal wire rods. It has the basic properties of metals, such as high strength, good toughness, good electrical conductivity and thermal conductivity, etc. In the production of steel reinforcement cages, these properties of steel bars are utilized, and through a series of processing techniques, they are made into steel reinforcement cage structures that meet the engineering requirements. For a steel reinforcement cage production device, reference can be made to a double steel reinforcement cage welder disclosed in the patent document with the authorized announcement number CN116765730B. The double steel reinforcement cage welder includes a front cage control console, a rear cage control console, a fixed rail and a pneumatic slide rail. The rear cage control console and the front cage control console are respectively slidably embedded in the top of the outer surface of the pneumatic slide rail. A front cylinder is rotatably embedded in the interior of the front cage control console, and a rear cylinder is rotatably embedded in the interior of the rear cage control console. A first motor is fixedly installed on the opposite sides of the front cylinder and the rear cylinder.

[0003] Hoop bars are the main components for forming steel reinforcement cages. When fixing the outer hoop bars, the inner expansion method is adopted. Multiple inner support columns are provided at multiple locations inside the front cylinder and the rear cylinder. The outside of the inner support columns is connected to a support plate. First motors are provided at both ends of the front cage control console and the rear cage control console. The first motors drive the sprockets through chains. At the same time, the outside of the lead screw is fixed inside the front cylinder and the rear cylinder through shaft seats to ensure the stability of the lead screw. The rotation of the lead screw drives the inner support columns sleeved with external threads to reciprocate inside the outer fixed ring. The thread setting on the lead screw is matched with the extending and contracting directions of the inner support columns to ensure the synchronous extension and contraction of the inner support columns, and then the hoop bars are spread, grabbed and fixed into the shape of a steel reinforcement cage. At the same time, the spreading length can be adjusted according to the size of the steel reinforcement cage. After the support plate spreads the hoop bars, the second motor drives the overall front cylinder and the rear cylinder to rotate synchronously, and the welding gun on the fixed rail welds the main bars, that is, the straight bars and the hoop bars. The hoop bars are spread and arranged on the outer ring of the support plate at each position, and the welding method adopts double-root sequential fixed welding.

[0004] It can be seen that the above-mentioned double-rebar cage welding machine uses the extension and contraction of multiple inner support columns to support the ring reinforcement, and the transmission is realized by the cooperation of chains and sprockets between the internal support columns. In actual production, this solution has certain shortcomings: (1) During the long-term transmission process of the chain and sprocket, friction will occur between the chain links and between the chain and sprocket teeth, resulting in chain elongation and sprocket tooth wear. This will not only affect the transmission accuracy, but may also cause the chain to derail, affect the normal operation of the device, and shorten the overall service life of the device. (2) In order to reduce wear and extend the service life, the chain sprocket transmission needs to be lubricated regularly. In the above-mentioned double-rebar cage welding machine, the chain sprocket is located inside the front barrel and the rear barrel, which makes the chain sprocket inconvenient to maintain and easy to cause failures. Summary of the invention

[0005] The invention provides a steel cage production device for supporting ring reinforcement, so as to solve the technical problems in the prior art that the chain and sprocket are difficult to maintain and have a short service life because the double steel cage welding machine uses a chain sprocket to drive an inner support column to support the ring reinforcement.

[0006] In order to solve the above problems, the present invention provides a steel cage production device for supporting ring reinforcement, which adopts the following technical solutions: A reinforcing cage production device for spreading ring reinforcement, comprising a front cage control console, a rear cage control console, a fixed rail and a pneumatic slide rail, wherein the rear cage control console and the front cage control console are respectively slidably embedded in the top of the outer surface of the pneumatic slide rail, a front cylinder is rotatably embedded in the interior of the front cage control console, and a rear cylinder is rotatably embedded in the interior of the rear cage control console, and further comprising: Multiple groups of propping components, which are arranged on the outer periphery of the front cylinder and / or the rear cylinder, and the propping components include a sliding structure and a propping frame for guiding movement along the length direction of the cylinder body of the front cylinder and / or the rear cylinder. During the sliding stroke of the sliding structure, the propping frame has a propping state of propping up the ring ribs outwardly and an initial state of being retracted to be arranged parallel to the cylinder body; The sliding stroke length of the sliding structure is adapted to the length of the produced steel cage; A driving assembly is arranged on the front cylinder and / or the rear cylinder, and is transmission-connected to the sliding structures in each group of supporting assemblies.

[0007] The beneficial effects of the above scheme are: the internal support column in the prior art is changed to a plurality of support components arranged outside, and at the same time, the support component is driven by the same external drive component to achieve the purpose of stably supporting the ring reinforcement. While achieving the support effect, the external support component and drive component make it easier for technicians to directly observe and operate during the on-site debugging process and the later maintenance and maintenance process, thereby improving the debugging and maintenance efficiency and significantly reducing the debugging and maintenance costs of the steel cage production device; because the drive component adopts an external setting method, the selection range of the drive component is greatly broadened, and it is no longer necessary to use a chain sprocket as a drive component that wears quickly, is easy to jam, has a high risk of damage and has a high maintenance cost in order to adapt to the narrow internal space, thereby avoiding the maintenance and maintenance difficulties caused by using the chain sprocket as the drive component. In summary, the present invention effectively solves the technical problems of the chain and sprocket being difficult to maintain and having a low service life in the prior art double steel cage welding machine that uses a chain sprocket to drive the internal support column to support the ring reinforcement.

[0008] Furthermore, each group of the supporting assemblies includes two supporting assemblies, the two supporting assemblies are collinear and are respectively arranged on the front cylinder and the rear cylinder, and the driving assembly is arranged on both the front cylinder and the rear cylinder.

[0009] The beneficial effect is that each group of supporting components includes two supporting components, so that the two supporting components in the group are respectively located on the front tube and the rear tube, and the two supporting components are collinear, and the two supporting components are used to accurately support different stress areas of the supporting frame, thereby alleviating the stress concentration phenomenon during single-point support, forming a multi-point coordinated mechanical closed loop, ensuring that the ring ribs can be effectively supported, and ultimately achieving the improvement of the stability and reliability of the group of supporting components.

[0010] Furthermore, the driving assembly on the front cylinder is simultaneously transmission-connected to each supporting assembly on the periphery of the front cylinder, and the driving assembly on the rear cylinder is simultaneously transmission-connected to each supporting assembly on the periphery of the rear cylinder.

[0011] The beneficial effect is: by simultaneously transmitting and connecting the driving assembly located on the rear cylinder to the various supporting assemblies on the periphery of the rear cylinder, this "one drive, multiple connections" distributed power architecture can achieve the purpose of one driving assembly driving multiple supporting assemblies at the same time, significantly reducing the hardware cost and driving energy consumption of driving multiple supporting assemblies, and ensuring the synchronization of the actions of each supporting assembly, thereby improving the yield of the steel cage.

[0012] Furthermore, the driving assembly includes an annular mounting seat arranged on the corresponding cylinder and an annular plate arranged adjacent to the annular mounting seat, a large gear is rotatably mounted on the annular mounting seat, and the annular plate has a number of small gears rotatably mounted on the annular plate that is the same as the number of supporting assemblies on the corresponding cylinder, each small gear is meshed with the large gear, and each small gear is transmission-connected to the sliding structure.

[0013] The beneficial effects are: gear transmission is used instead of chain sprocket transmission. During the power transmission process, the gears realize power transmission through precise meshing, and their contact stress is evenly distributed, avoiding energy loss caused by relaxation or jitter of the chain transmission. By optimizing the gear module, number of teeth and pressure angle parameters, a large transmission ratio transmission chain can be constructed in a compact space to meet the torque amplification requirements under complex working conditions. At the same time, the wear of the gear meshing surface presents uniform characteristics. Through the forced lubrication system, a synthetic lubricating oil film is continuously supplied, and regular tooth surface polishing maintenance is combined to significantly reduce the risks of failures such as pitting and bonding, and effectively reduce the risks of tooth surface wear and fatigue damage. While improving the transmission efficiency, the maintenance period of the device is effectively extended.

[0014] Furthermore, the driving assembly also includes a first motor fixed on the annular plate, and an output gear meshing with the large gear is installed at the output end of the first motor, and the output gear is used to drive the large gear to rotate, and then drive each small gear to rotate.

[0015] Furthermore, a screw rod is fixed in each of the pinions, and the sliding structure includes a sliding block threadably assembled on the screw rod, an inclined rod is hinged on the sliding block, and the other end of the inclined rod is hinged to the supporting frame.

[0016] The beneficial effect is that the diagonal rod realizes the transmission of force in three-dimensional space through the double hinge point topology (that is, one end of the diagonal rod is hinged to the sliding block, and the other end is hinged to the supporting frame), optimizes the mechanical transmission path, and makes the cooperation between the diagonal rod and the sliding block have better stability, and can evenly distribute the force to each supporting point, which is not easy to tilt or shake.

[0017] Furthermore, there are two inclined rods, which are arranged on both sides of the sliding block respectively, and a pulley is installed at the bottom of the sliding block to improve the smoothness of the movement of the sliding block.

[0018] Furthermore, the annular plate has fixed seats corresponding to the number of pinions, and a screw is rotatably installed in each fixed seat. The front cylinder and the rear cylinder are arranged with multiple guide seats for the screw to pass through, and each guide seat has a bearing for mounting the screw. The fixed seat and each guide seat form a multi-stage guide structure for guiding the screw to improve the stability of the screw rotation.

[0019] Beneficial effects: The fixed seat and each guide seat constitute a multi-stage guide structure. The fixed seat provides an initial rotation support point for the screw, and multiple guide seats further constrain the movement trajectory of the screw. This multi-stage guide can effectively reduce the shaking and deviation of the screw during rotation, so that the screw always rotates stably along the predetermined path, avoiding movement jams or abnormal wear caused by shaking, extending the service life of the entire device, and reducing maintenance costs and the frequency of parts replacement.

[0020] Furthermore, the supporting frame includes a rectangular frame and a rectangular supporting plate, a horizontal axis is rotatably installed in the rectangular frame, the rectangular supporting plate is fixed on the horizontal axis, and one of the diagonal rods is hinged on both sides of the rectangular supporting plate in the width direction.

[0021] Furthermore, the front cylinder is connected to the rear cylinder, and a second motor is provided at one end of the front cage control console. The second motor drives the front cylinder to rotate through a gear assembly, thereby driving the rear cylinder to rotate synchronously.

[0022] The beneficial effect is: by connecting the front cylinder with the rear cylinder, using the second motor to drive the front cylinder to rotate, so as to drive the rear cylinder to rotate synchronously, it is ensured that the front and rear ring bars rotate at completely consistent angles and speeds, avoiding defects such as ring bar misalignment and pitch variation caused by speed difference, and further improving the yield rate of the steel cage.

[0023] The beneficial effects of the steel cage production device for supporting ring reinforcement provided by the present invention are: (1) By replacing the internal support column in the prior art with multiple groups of support components arranged outside, the support components are driven by the external drive components to support the ring ribs, thereby broadening the selection range of the drive components. When selecting the drive components, there is no need to select chain gears that are easy to wear and have high maintenance costs due to the limitation of internal space. At the same time, this arrangement of the external support components and drive components is convenient for technicians to directly observe and operate. While achieving the support effect, the debugging efficiency and maintenance efficiency of the support components and drive components are improved, and the time cost of debugging and maintenance is reduced. (2) By arranging two support components in sections on an axis, and arranging the two support components on the front tube and the rear tube respectively, the two support components take the middle section of the support frame as the core control area, the front end support offsets the bending moment stress, and the rear end support suppresses the lateral displacement, forming a symmetrically distributed mechanical balance system. When the support frame is subjected to external force, the two support components generate a reverse force to form a closing moment, effectively balancing the radial deformation and axial displacement, fundamentally improving the stability of the support effect of the support frame, and ensuring that the ring reinforcement is effectively supported; (3) Multiple supporting components are connected and transmitted simultaneously through one driving component, which ensures the synchronous movement of multiple supporting components, maximizes the power transmission efficiency, eliminates the problem of uneven stress caused by the asynchronous movement of multiple supporting components, reduces the energy consumption and hardware cost of driving multiple supporting components, and improves the yield rate of steel cage; (4) The chain and sprocket drive is replaced by a gear drive. A closed power transmission system is constructed through a pair of precisely meshing gears. Compared with the chain and sprocket drive, which is prone to problems such as slack and tooth skipping, the gear drive transmits power in a point-contact or line-contact manner, which can effectively reduce the stress intensity per unit area, reduce the pitting corrosion of tooth surfaces caused by impact loads, greatly improve the meshing accuracy, thereby reducing energy loss, improving the energy transmission efficiency, and being able to achieve a larger transmission ratio, reducing tooth surface wear and fatigue damage.

[0026] An embodiment of the steel cage production device for expanding hoop bars provided by the present invention: As Figures 1 to 10 As shown, the steel cage production device for expanding hoop bars includes a front cage console 1, a rear cage console 2, a fixed rail 3 and a pneumatic slide rail 4. The rear cage console 2 and the front cage console 1 are respectively slidably embedded in the top of the outer surface of the pneumatic slide rail 4. The front cylinder 5 is rotatably embedded in the front cage console 1, and the rear cylinder 6 is rotatably embedded in the rear cage console 2. On this basis, the whole device further includes multiple sets of supporting components and driving components.

[0027] The concept of the present invention is to change the inner support columns in the prior art to multiple sets of supporting components arranged outside. At the same time, the same external driving components are used to drive the supporting components to achieve the purpose of firmly expanding the hoop bars. While achieving the expansion effect, the external supporting components and driving components enable technicians to directly observe and operate more easily during the on-site debugging process and the later maintenance and repair process, improving the debugging and maintenance efficiency and significantly reducing the debugging and maintenance costs of the steel cage production device; due to the external arrangement of the driving components, the selection range of the driving components is greatly broadened.

[0028] As Figures 1 to 6 As shown, multiple sets of supporting components are arranged on the outer periphery of the front cylinder 5 and / or the rear cylinder 6. The supporting components include a sliding structure for guiding and moving along the length direction of the cylinder body of the front cylinder 5 and / or the rear cylinder 6 and a supporting frame. In the sliding stroke of the sliding structure, the supporting frame has a supporting state of expanding the hoop bars outward and an initial state of retracting to be arranged parallel to the cylinder body; the sliding stroke length of the sliding structure is adapted to the length of the steel cage to be produced.

[0029] It should be noted that a welding structure is also arranged beside the front cage console 1 and the rear cage console 2. When the hoop bars are expanded to the set position, the welding structure is used to weld the hoop bars and straight bars (not shown in the figure) to form a steel cage. Since the welding structure belongs to the prior art and does not involve the improvement points of this application, it will not be described in depth.

[0030] As Figures 1 to 4As shown, specifically, each group of the supporting components includes two supporting components, the two supporting components are collinear and are respectively arranged on the front tube 5 and the rear tube 6, and the driving components are arranged on the front tube 5 and the rear tube 6. The advantage of this arrangement is that two supporting components are arranged in sections on one axis, and the use effect of the two supporting components is more stable, which can ensure that the ring ribs are effectively supported. In other embodiments, each group of supporting components can also include only one supporting component, which can cover the front tube and the rear tube at the same time.

[0031] In other words, the two supporting components can provide precise support for different stress-bearing areas of the supporting frame, alleviate the stress concentration phenomenon during single-point support, form a multi-point coordinated mechanical closed loop, ensure that the ring reinforcement can be effectively supported, and ultimately achieve improved stability and reliability of this group of supporting components.

[0032] In addition, the advantage of the two propping components being collinear is that they can use each other's positions as references during arrangement, thereby improving arrangement accuracy. In other embodiments, the two propping components may not be collinear, as long as they can be opened synchronously to prop up the ring ribs.

[0033] The driving assembly on the front cylinder 5 is simultaneously connected to each supporting assembly on the periphery of the front cylinder 5, and the driving assembly on the rear cylinder 6 is simultaneously connected to each supporting assembly on the periphery of the rear cylinder 6. In this way, one driving assembly can drive multiple supporting assemblies at the same time, which not only reduces energy consumption, but also enables each supporting assembly to act synchronously, thereby improving the yield rate of the steel cage.

[0034] This "one drive, multiple connections" distributed power architecture can achieve the purpose of one drive assembly driving multiple support assemblies at the same time, significantly reducing the hardware cost and drive energy consumption of driving multiple support assemblies, and ensuring the synchronization of the actions of each support assembly, thereby improving the yield rate of the steel cage. In other embodiments, each support assembly can be equipped with a separate drive assembly.

[0035] The driving assembly is arranged on the front cylinder 5 and / or the rear cylinder 6, and is transmission-connected to the sliding structures in each group of the supporting assemblies.

[0036] like Figure 5 As shown, specifically, the driving assembly includes an annular mounting seat 7 arranged on the corresponding cylinder and an annular plate 8 arranged adjacent to the annular mounting seat 7, a large gear 9 is rotatably mounted on the annular mounting seat 7, and the annular plate 8 has small gears 10 rotatably mounted on the annular plate 8, the same number as the number of the supporting assemblies on the corresponding cylinder, each small gear 10 is meshed with the large gear 9, and each small gear 10 is transmission-connected to the sliding structure.

[0037] The use of gear transmission instead of chain sprocket transmission reduces the loss in the energy transmission process, and through reasonable gear arrangement, a larger transmission ratio can be achieved in a smaller space. At the same time, under normal working conditions, the service life of the gear transmission is longer. The wear of the gears is relatively uniform, and through proper lubrication and maintenance, the tooth surface wear and fatigue damage can be effectively reduced.

[0038] like Figure 10 As shown, the driving assembly also includes a first motor 11 fixed on the annular plate 8, and an output gear 12 meshing with the large gear 9 is installed at the output end of the first motor 11. The output gear 12 is used to drive the large gear 9 to rotate, and then drive each small gear 10 to rotate.

[0039] like Figures 6 to 8 As shown, a screw rod 13 is fixed in each pinion 10, and the sliding structure includes a sliding block 14 threadedly assembled on the screw rod 13, and an inclined rod 15 is hinged on the sliding block 14, and the other end of the inclined rod 15 is hinged to the support frame. The inclined rod 15 and the sliding block 14 have good stability when they cooperate, and can evenly distribute the force to each supporting point, and are not prone to tilting or shaking.

[0040] That is, the diagonal rod 15 realizes the transmission of force in three-dimensional space through the double hinge point topology (that is, one end of the diagonal rod 15 is hinged to the sliding block 14, and the other end is hinged to the supporting frame), optimizes the mechanical transmission path, and makes the cooperation between the diagonal rod 15 and the sliding block 14 have better stability. In other embodiments, the sliding structure can also be set as a scissors-type structure, and a slider is set at the bottom of the scissors-type structure, and the slider is threaded on the screw rod 13.

[0041] In this embodiment, there are two inclined rods 15, which are arranged on both sides of the sliding block 14, and a pulley 23 is installed at the bottom of the sliding block 14 to improve the smoothness of the movement of the sliding block 14. In other embodiments, the number of inclined rods 15 can be adjusted according to actual needs, and can also be one or three.

[0042] The annular plate 8 is provided with fixing seats 16 corresponding to the number of pinions 10, and a screw 13 is rotatably installed in each fixing seat 16. A plurality of guide seats 24 for the screw 13 to pass through are arranged on the front cylinder 5 and the rear cylinder 6, and each guide seat 24 has a bearing for mounting the screw 13. The fixing seat 16 and each guide seat 24 form a multi-stage guiding structure for guiding the screw 13 to improve the rotation stability of the screw 13.

[0043] The fixed seat 16 and each guiding seat 24 form a multi-stage guiding structure. The fixed seat 16 provides an initial rotational support point for the screw rod 13, and the multiple guiding seats 24 further restrict the movement trajectory of the screw rod 13. This multi-stage guiding can effectively reduce the wobbling and deviation of the screw rod 13 during rotation, enabling the screw rod 13 to always rotate stably along a predetermined path, avoiding motion jamming or abnormal wear caused by wobbling, extending the service life of the entire device, and reducing the maintenance cost and the frequency of component replacement.

[0044] This stability is very important for the production of the steel reinforcement cage. Because after the circular reinforcement bars are propped up, the next procedure is welding. Therefore, the circular reinforcement bars need to be stably propped up to avoid displacement of the circular reinforcement bars during welding, which affects the quality of the entire steel reinforcement cage. Therefore, in other embodiments, the form of the above multi-stage guiding structure can also be changed, such as increasing the number of fixed seats corresponding to each screw rod.

[0045] As Figures 6 to 8 shown, the propping-up frame includes a rectangular frame 17 and a rectangular supporting plate 18. A transverse shaft 19 is rotatably installed in the rectangular frame 17, and the rectangular supporting plate 18 is fixed on the transverse shaft 19. One inclined rod 15 is hinged on each side of the rectangular supporting plate 18 in the width direction.

[0046] Finally, referring to Figure 9 , considering the welding of the circular reinforcement bars, in this embodiment, the front cylinder 5 is connected to the rear cylinder 6. A second motor 20 is provided at one end of the front cage control console 1. The second motor 20 drives the front cylinder 5 to rotate through a gear assembly, and then drives the rear cylinder 6 to rotate synchronously.

[0047] Specifically, the gear assembly includes a first gear 21 and a second gear 22, which are meshed with each other. The first gear 21 is arranged at the output end of the second motor 20, and the second gear 22 is fixed on the outer periphery of the front cylinder 5. The front cylinder 5 and the rear cylinder 6 rotate synchronously, ensuring that the circular reinforcement bars on the front side and the rear side can rotate synchronously, avoiding defects such as misalignment of the circular reinforcement bars and variation of the pitch caused by the speed difference, and further improving the yield rate of the steel reinforcement cage.

[0048] The working principle of the steel reinforcement cage production device provided by the present invention for propping up circular reinforcement bars is as follows: The pneumatic slide rail 4 is used to control the front cage control console 1 and the rear cage control console 2 to approach each other. When their relative positions meet the requirements, the front cylinder 5 and the rear cylinder 6 are connected; the first motors 11 on the front cylinder 5 and the rear cylinder 6 work simultaneously. By driving the large gear 9 to rotate, and then driving each small gear 10 to rotate. Under the action of the small gears 10, while the screw rods 13 rotate, they drive the sliding blocks 14 to move along the outer periphery of the cylinder body, and the inclined rods 15 expand outward to prop up the circular reinforcement bars into the shape of a steel reinforcement cage; When the circular reinforcement bars are propped up, the second motor 20 rotates to drive the front cylinder 5 and the rear cylinder 6 to rotate synchronously, and then adjust the posture of the circular reinforcement bars. The welding structure welds the straight reinforcement bars (not shown in the figure) extending forward and backward and the circular reinforcement bars.

[0049] Based on the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for facilitating the description of the solution of the present invention and simplifying the description. Therefore, the above terms indicating orientation or positional relationships cannot be understood or construed as limitations on the solution of the present invention.

[0050] In addition, in the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
