Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and more particularly to a steel cage production device and a production method thereof. Background Art

[0002] The steel cage is an important part of the pile foundation and is the main stress-bearing composite material for the pile foundation to withstand tensile stress. The quality of the steel cage processing directly affects the quality of the pile foundation.

[0003] Nowadays, many major buildings adopt the on-site cast-in-place reinforced concrete scheme during construction. Therefore, when producing the steel cage, the design requires mechanical connection of the main steel bars in the steel cage. The current production equipment for threading the main steel bars is a single threading machine, which can only perform end rib stripping and threading on the cut main steel bars. It requires the coordination of multiple workers for production, and the processing process is relatively cumbersome, posing high requirements for the labor intensity of workers. Because mechanical connection requires continuous and long-term cumbersome operations, the mechanical noise is loud during work, which brings a large physical and mental burden to workers, easily causing labor fatigue and work-related injuries. Moreover, the mechanical connection equipment runs unstably and requires frequent maintenance and repair, which not only increases the maintenance cost, but also causes project delays and a decline in production efficiency. At the same time, there are certain operation safety risks and it cannot meet the high-quality construction requirements, which may lead to insecure steel bar connections and affect the safety and durability of the project.

[0029] A method for producing a steel cage, characterized in that it is based on a steel cage production device according to any one of claims 1-9, and includes:

[0030] S1. The raw materials are stored in the storage part in the form of steel bars. The storage part can accommodate a large amount of steel bars and provide the required raw materials according to needs;

[0031] S2. The raw materials fall onto the feeding part through the storage part. During the synchronous operation of several plate conveyors in the feeding part, the steel bar raw materials at the bottommost position will smoothly get stuck in the material clamping grooves at the same position of several plate conveyors, and then be driven by several plate conveyors to break away from the storage part. Thus, the feeding of the steel bar raw materials at the bottommost position in the storage part is completed in sequence, and intermittent feeding is carried out by the feeding part.

[0032] S3. When the steel bar raw materials conveyed by the feeding part move between the two preliminary processing parts, the feeding part stops working, and the two conveying parts set work simultaneously. Control the two preliminary processing parts to move closer to each other so that both ends of the steel bar raw materials to be preliminarily processed can be respectively placed in two of the fixing parts and be fixed. At the same time, two of the positioning parts work to clamp and fix the middle part of the steel bar raw materials to be preliminarily processed.

[0033] S4. The two preliminary processing parts work. Under the respective pushing of two electric push rods, the two sawing machines respectively and quickly and accurately saw off the redundant parts at both ends of the steel bar. After the cutting is completed, the two first electric sliding tables set work, respectively controlling the two first motors to drive the two outer chamfering devices to approach and perform operations of grinding and chamfering the two ends of the steel bar raw materials.

[0034] S5. After the preliminary processing of the steel bar raw materials is completed, the fixing parts and the positioning parts release the fixing and limiting of the steel bar. Under the conveying of the feeding part, when the preliminarily processed steel bar moves between the two secondary processing parts, it stops moving. The two conveying parts set work simultaneously. Control the two secondary preliminary processing parts to move closer to each other. At this time, the two fixing parts and the positioning parts clamp and limit the preliminarily processed steel bar raw materials, and the two second electric sliding tables set work, respectively controlling the two second motors to drive the two tapping tool holders to perform threading operations on the two ends of the steel bar raw materials. When the steel bar raw materials are undergoing secondary processing operations, the subsequent steel bar raw materials conveyed by the feeding part are undergoing preliminary processing synchronously.

[0035] S6. After the secondary processing of the steel bar raw materials is completed, the fixing parts and the positioning parts release the fixing and limiting of the steel bar. Under the conveying of the feeding part, the processed steel bar raw materials are conveyed to the finished product rack for storage.

[0036] S7. The processed finished steel bars are transported to the steel bar positioning rack by a hoisting device, so that the welding robot moves to the designated position corresponding to the steel bar positioning rack. Under the control of the rail vehicle and the third electric sliding table, the welding robot moves and performs welding operations on the steel bars to be welded at the designated position, thereby welding the steel bars on the steel bar positioning rack into a steel bar cage.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The steel cage production equipment and production method can achieve high-precision steel bar cutting, grinding, and threading operations through the two primary treatment units and two secondary treatment units set. With the cooperation of the material storage unit and the material feeding unit, it can achieve streamlined construction, enabling the entire production line to operate continuously. This can significantly reduce the labor intensity of workers, improve production efficiency and construction speed, reduce the risk of workers coming into contact with high-temperature and sharp components, provide a safer operating environment, ensure the personal safety of workers, and reduce the accident risk caused by careless operation.

[0039] 2. Before threading the two ends of the steel bar raw material through the secondary treatment unit, the primary treatment unit can complete chamfering and grinding of the two ends of the steel bar raw material, effectively improving the threading accuracy during the subsequent threading process of the steel bar raw material, effectively reducing the stress concentration on both sides of the steel bar end face, thereby increasing the allowable load and strength of the steel bar, and avoiding direct contact between the tapping tool holder and the edges of the two ends of the steel bar, reducing minute edge deformation. At the same time, before the primary processing and secondary processing of the steel bar, through the several fixing units and several positioning units set, the movement of the steel bar raw material can be effectively restricted, preventing the steel bar raw material from deforming or changing position during the processing, affecting the next processing operation, and effectively improving the processing quality of the steel bar.

[0053] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0054] As Figure 1-10 shown, a steel cage production device and production method include: a storage part 1, and the storage part 1 is fixed on the ground 2;

[0055] a feeding part 3, the feeding part 3 is fixed on the ground 2, and the feeding end of the feeding part 3 is arranged directly below the storage part 1;

[0056] a conveying part 4, two conveying parts 4 are both installed on the ground 2 and symmetrically arranged on both sides of the feeding part 3;

[0057] The primary processing unit 5 and the secondary processing unit 6, both of the two primary processing units 5 and the two secondary processing units 6 are respectively installed on the two conveying units 4, and the two primary processing units 5 are close to the feeding end of the feeding unit 3, and the two secondary processing units 6 are close to the discharging end of the feeding unit 3;

[0058] The fixing part 7, several of the fixing parts 7 are respectively installed on the two primary processing units 5 and the two secondary processing units 6;

[0059] The positioning part 8, several of the positioning parts 8 are symmetrically arranged on the ground 2 and the conveying unit 4, and several of the positioning parts 8 correspond to the two primary processing units 5 and the two secondary processing units 6;

[0060] The welding part 9, the welding part 9 is fixedly installed on the ground 2, where

[0061] The feeding unit 3 is used to drive the steel bars stored in the storage unit 1 to be intermittently conveyed, and during the conveying process, the two ends of the steel bars are processed by the two primary processing units 5 and the two secondary processing units 6 arranged;

[0062] Before the steel bars are processed by the two primary processing units 5 and the two secondary processing units 6, the fixing unit 7 cooperates with a number of positioning units 8 to clamp and fix the steel bars. During specific operation, the raw steel bars to be processed are stacked and stored in the storage unit 1, and the required raw materials are provided as needed. When the feeding unit 3 is operating, the raw steel bars in the storage unit 1 can be intermittently taken out and fed, so that the raw steel bars are sequentially conveyed to the position between the two primary processing units 5 and the two secondary processing units 6. Finally, the processed raw steel bars are sent to the finished product rack 16 for storage. Under the control of the two primary processing units 5, the two ends of the raw steel bars can be cut and chamfered and polished simultaneously, ensuring that the length of the finished steel bars meets the assembly requirements of the steel cage. At the same time, the steel bars after chamfering and polishing can avoid the appearance of horseshoe-shaped cuts on the steel bars, effectively improving the threading accuracy during the subsequent threading process of the raw steel bars, and effectively reducing the stress concentration on both sides of the steel bar end face, thereby improving the allowable load and strength of the steel bars, and avoiding the direct contact between the threading tool holder 29 and the edges of the two ends of the steel bars, reducing the micro-deformation at the edges, and thus ensuring the quality of the threading processing; After the preliminary processing of the raw steel bars, under the control and processing of the two secondary processing units 6, threading is carried out simultaneously at both ends of the raw steel bars after preliminary processing, ensuring the firm connection of the steel bars and facilitating subsequent construction operations and use. The steel bar sawing and threading are carried out in a streamlined manner, and the numerical control technology is used for automated cutting and threading operations, greatly improving the threading accuracy, ensuring the firmness and stability of the steel bar connection, and the automated threading operation reduces the occurrence of human errors, reduces the threading error rate, improves the quality and reliability of the steel bar connection, and can greatly reduce the labor input, reduce the risk of workers contacting high-temperature and sharp components, reduce the labor intensity of workers, improve the construction efficiency and benefits, and also provide a safer operating environment to ensure the personal safety of workers; And due to the simultaneous position control of the two conveying units 4 on the two primary processing units 5 and the two secondary processing units 6, when the two secondary processing units 6 are processing the steel bars, the two primary processing units 5 are also processing the steel bars simultaneously. And the primary processing unit 5 has two operation processes of cutting and chamfering and polishing, which are coordinated with the overall processing time of the threading operation in the secondary processing unit 6 to ensure the processing synchronization of the primary processing unit 5 and the secondary processing unit 6, effectively reducing the processing interruption time between the two primary processing units 5 and the two secondary processing units 6, and enabling continuous operation of the steel bar processing, improving the production efficiency and construction speed; At the same time, before the primary processing and secondary processing of the steel bars, through the setting of a number of fixing units 7 and a number of positioning units 8, the movement of the raw steel bars can be effectively restricted, preventing the raw steel bars from deforming or changing positions during the processing, affecting the next processing operation, and effectively improving the processing quality of the steel bars;The finished steel bar raw materials can be transported by a hoisting device to the welding section 9. The welding robot 56 is controlled by a rail vehicle 54 and a third electric slide 55. After the welding robot 56 adjusts the optimal welding parameters through trial welding and presets relevant welding parameters numerically controlled, it realizes mechanical automatic steel bar welding, ensuring the welding quality and stability of the steel bars, and greatly improving the construction efficiency of the welding process. Welding does not require manual intervention, reducing construction time and labor costs. At the same time, realizing automatic welding helps to improve work safety. The robot welding technology can transfer the welding process from workers, reducing the risk of workers being exposed to harmful environments.

[0063] Optionally, the storage section 1 includes a bracket 10 fixed on the ground 2, a storage table 11 installed on the bracket 10, and a blanking frame 12 connected to the bottom of the storage table 11. During use, the storage table 11 can accommodate a large number of steel bars and provide the required raw materials as needed. The steel bar raw materials stacked on the storage table 11 will fall into the blanking frame 12 along the storage table 11, facilitating the sequential discharging of a large number of steel bar raw materials in cooperation with the feeding section 3.

[0064] Optionally, the feeding section 3 includes a feeding table 13 installed on the ground 2, a number of plate conveyors 14 installed equidistantly on the feeding table 13, a number of material clamping grooves 15 respectively opened equidistantly on the number of plate conveyors 14, and a finished product rack 16 installed at the discharging ends of the number of plate conveyors 14;

[0065] The lowest height of the number of material clamping grooves 15 is the same as the upper surface height of the feeding table 13;

[0066] The distance between the plate conveyor 14 and the material clamping groove 15 is less than the diameter of the raw material steel bar. During use, the number of plate conveyors 14 set work simultaneously, so that the material clamping grooves 15 at the same positions on the number of plate conveyors 14 will synchronously pass through the bottom of the storage section 1, taking out the steel bar raw materials stored in the storage section 1. Since the material clamping grooves 15 are arranged equidistantly on the plate conveyor 14, the taking and sending of the steel bar raw materials can be completed intermittently, facilitating the separate processing of the initial processing section 5 and the secondary processing section 6. The distance between the plate conveyor 14 and the material clamping groove 15 is less than the diameter of the raw material steel bar, which can prevent the steel bar raw materials in the storage section 1 from detaching from the storage section 1 when the material clamping groove 15 does not pass through the storage section 1. The processed steel bars can fall on the finished product rack 16 for storage, meeting the requirements of large-scale projects. The plate conveyor 14 is a mature technical structure in the prior art and will not be elaborated here.

[0067] Optionally, the primary processing unit 5 includes a first control box 17 installed on the conveying unit 4, a first electric slide table 18 installed on the first control box 17, a first motor 19 fixed on the first electric slide table 18, an external chamfering tool 20 detachably installed at the output end of the first motor 19, a grinding blade 21 arranged in the external chamfering tool 20, a control frame 22 installed on the side wall of the first control box 17, a sawing machine 23 hingedly installed on the control frame 22, an electric push rod 24 hingedly installed on the top of the control frame 22, and a blanking groove 25 opened on the control box;

[0068] The telescopic end of the electric push rod 24 is hingedly connected to the upper end of the sawing machine 23. When the steel bar raw material moves between the two primary processing units and is controlled by the two conveying units 4, the two first control boxes 17 approach each other. After the two fixing parts 7 fix the two ends of the steel bar raw material, under the push of the two electric push rods 24, the two sawing machines 23 are respectively controlled to quickly and accurately saw the two ends of the steel bar raw material, and the appearance of the horseshoe-shaped cut of the steel bar can be avoided, which is helpful for the subsequent threading operation. Then, under the control of the two first electric slide tables 18, the two first motors 19 drive the two external chamfering tools 20 to approach the steel bar, and with the cooperation of the grinding blade 21, chamfering and grinding operations are performed on the two ends of the steel bar, effectively improving the threading accuracy during the subsequent threading process of the steel bar raw material, and effectively reducing the stress concentration on both sides of the steel bar end face, thereby improving the allowable load and strength of the steel bar, and avoiding the direct contact between the tapping tool holder 29 and the edges of the two ends of the steel bar, reducing the minor deformation at the edges, thereby ensuring the quality of the threading processing. The first electric slide table 18 is an existing mature technical structure and will not be elaborated here.

[0069] Optionally, the secondary processing unit 6 includes a second control box 26 installed on the conveying unit 4, a second electric slide table 27 installed on the second control box 26, a second motor 28 fixed on the second electric slide table 27, and a tapping tool holder 29 detachably installed at the output end of the second motor 28;

[0070] The tapping tool rest 29 and the axis of the external chamfering device 20 are at the same height. After the initial processing of the steel bar raw material is completed, it moves between the two secondary processing parts. Under the control of the two conveying parts 4, the two second control boxes 26 approach each other. After the two fixing parts 7 complete the fixing of both ends of the steel bar raw material, under the control of the two second electric sliding tables 27, the two second motors 28 drive the tapping tool rest 29 to approach the steel bar, and then threading operation is carried out on the steel bar. The automated threading operation can greatly reduce the labor input, reduce the labor intensity of workers, improve the construction efficiency and benefits, and reduce the risk of workers contacting high-temperature and sharp components. It also provides a safer operating environment and guarantees the personal safety of workers. Among them, the second electric sliding table 27 is a mature technical structure existing in the art and will not be elaborated here.

[0071] Optionally, the fixing part 7 includes a lifting frame 30 installed on the first control box 17 or the second control box 26, a first hydraulic rod 31 installed on the lifting frame 30, an extrusion seat 32 fixed on the telescopic end of the first hydraulic rod 31 and slidably connected to the lifting frame 30, two first fixing blocks 33 symmetrically fixed on the extrusion seat 32, a supporting seat 34 installed on the lifting frame 30, a second fixing block 35 fixed on the supporting seat 34 and arranged between the two first fixing blocks 33, and a number of fixing grooves 36 opened on the second fixing block 35 and the two first fixing blocks 33. When the steel bar raw material is moved between the two primary processing parts 5 or the two secondary processing parts 6 by the feeding part 3 and under the control of the two conveying parts 4, the two primary processing parts 5 and the two secondary processing parts 6 move closer to each other actively. When the conveying part 4 is controlled to move to the designated position, one end of the steel bar raw material will be inserted between the second fixing block 35 and the two first fixing blocks 33. Under the push of the first hydraulic rod 31, the extrusion seat 32 is pushed to move on the lifting frame 30 and approach the supporting seat 34. Then, the second fixing block 35 and the two first fixing blocks 33 approach each other, so that one end of the steel bar raw material will be clamped in a number of fixing grooves 36, effectively improving the stability of the steel bar raw material during primary processing and secondary processing, and avoiding deformation of the steel bar raw material during primary processing and secondary processing, which affects the processing quality.

[0072] Optionally, the positioning part 8 includes an assembly frame 37 fixed on the ground 2, a second hydraulic rod 38 installed in the assembly frame 37, a control board 39 fixed on the telescopic end of the second hydraulic rod 38, two wedge-shaped clamping blocks 40 symmetrically and slidably installed on the upper surface of the control board 39, two return springs 41 respectively fixed at both ends to the two wedge-shaped clamping blocks 40, and an extrusion groove 42 opened on the feeding table 13 and adapted to the two wedge-shaped clamping blocks 40;

[0073] The two wedge-shaped clamping blocks 40 are fitted and slidably inserted into the extrusion groove 42. When the feeding part 3 drives the steel bar raw material between the two primary processing parts 5 or the two secondary processing parts 6, several positioning parts 8 arranged work. The second hydraulic rod 38 is activated to push the control plate 39 upward. Since both of the two wedge-shaped clamping blocks 40 are abutted against the inner wall of the extrusion groove 42, when the two wedge-shaped clamping blocks 40 are pushed upward, they will be extruded to slide on the control plate 39 and approach each other, thereby clamping and positioning the steel bar raw material located between the two wedge-shaped clamping blocks 40, ensuring the stability of the position of the steel bar raw material after it stops moving, and effectively restricting the displacement of the steel bar raw material during primary processing and secondary processing, avoiding the displacement of one end of the steel bar raw material driven by one of the fixing parts 7 during the primary processing or secondary processing of the steel bar raw material, which affects the subsequent movement of the steel bar raw material; and when the steel bar raw material needs to be controlled by the feeding part 3 to move, the second hydraulic rod 38 controls the control plate 39 to drive the two wedge-shaped clamping blocks 40 to move downward, and under the elastic force of the two return springs 41, the two wedge-shaped clamping blocks 40 can be pushed to move relative to each other on the control plate 39, facilitating the subsequent clamping and positioning operation of the steel bar raw material.

[0074] Optionally, the conveying part 4 includes a support frame 43 fixed on the ground 2, a third motor 44 fixed on the lower surface of the control frame 22, a control lead screw 45 with one end rotatably connected to the support frame 43 and the other end fixedly connected to the output end of the third motor 44, a control block 46 threadedly connected to the control lead screw 45, a chute 47 opened on the support frame 43, two slide rails 48 symmetrically fixed on the support frame 43, a plurality of sliders 49 movably installed on the two slide rails 48, an assembly table 50 fixed on the plurality of sliders 49, and a connecting plate 51 with one end fixedly connected to the control block 46, passing through the chute 47 at the other end, and fixedly connected to the assembly table 50;

[0075] The first control box 17 and the second control box 26 are both fixed on the assembly table 50. When the steel bar raw material on the feeding part 3 is sent to the designated position, the set third motor 44 starts to work, driving the control lead screw 45 to rotate, and then the control block 46 drives the assembly table 50 to move horizontally through the sliding of the connecting plate 51 in the chute 47. With the change of the rotation direction of the output end of the third motor 44, the assembly table 50 can be controlled to approach or move away from the feeding table 13. When the two conveying parts 4 work simultaneously, the two primary processing parts 5 and the two secondary processing parts 6 can be driven to approach the feeding table 13 simultaneously, enabling the two steel bar raw materials to be respectively subjected to primary processing and secondary processing, ensuring the processing efficiency of the steel bar raw material.

[0076] Optionally, the welding part 9 includes a steel bar positioning frame 52 for carrying the steel bar cage, a horizontal track 53 and a rail vehicle 54 arranged on the ground 2, a third electric slide 55 assembled on the rail vehicle 54, and a welding robot 56 fixed on the third electric slide 55.
