Description

Technical Field

[0001] The invention relates to the technical field of steel mesh processing, and in particular to a steel mesh rapid processing device for precast concrete components. Background Art

[0002] The grid structure of the steel mesh allows the concrete components to distribute the load more evenly when they are subjected to stress, thereby improving the overall stiffness and stability of the components. This helps reduce the risk of deformation and damage to the components, making the structure more durable. The application of steel mesh can also increase the seismic performance of precast concrete components. When natural disasters such as earthquakes occur, the steel mesh can absorb and disperse the energy of seismic waves, reduce the damage to components caused by earthquakes, and maintain the integrity and stability of the structure. The processing device of the steel mesh in the prior art has a mechanical structure in which a transverse reinforcement feeding device is arranged below the welding module. The adjacent upper and lower welding blocks of the welding device are close to each other and there is no gap between them. The transverse reinforcement and the longitudinal reinforcement are welded. During the processing, in order to avoid the interference of the transverse reinforcement feeding device below with the welding device, welding needs to be performed from one side. After the welding is completed, the welding device is slid to the other side through the sliding assembly to weld the same transverse reinforcement and longitudinal reinforcement again. In the process of welding a transverse reinforcement and a longitudinal reinforcement, two or more welding processes are required, which may seriously affect the welding efficiency of the steel mesh, may reduce the number of steel meshes produced per day, and affect the production efficiency of the factory.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] refer to Figures 1 to 11The present invention provides a fast processing device for precast concrete components, comprising a longitudinal reinforcement conveying frame 4 for simultaneously conveying a plurality of longitudinal reinforcement bodies 8, a coil 2 for conveying reinforcements, a straightening machine 3 for straightening and shearing the reinforcements, and a numerical control mesh drawing mechanism 1 for synchronously drawing the reinforcement mesh, wherein a transverse reinforcement conveying frame 9 for conveying transverse reinforcement bodies 7 is detachably mounted above the longitudinal reinforcement conveying frame 4, a welding frame 5 for welding the transverse reinforcement bodies 7 located above and the longitudinal reinforcement bodies 8 located below is arranged between the longitudinal reinforcement conveying frame 4 and the numerical control mesh drawing mechanism 1, and folding members for bending the transverse reinforcement bodies 7 are also arranged at both ends of the welding frame 5. Bending mechanism 6, the welding frame 5 includes an upper welding block 502 and a lower welding block 501 for welding, the total length of the multiple upper welding blocks 502 or lower welding blocks 501 that are closely attached to each other is greater than or equal to the total length of the transverse rib body 7, and the end of the transverse rib conveying frame 9 facing the welding frame 5 is provided with a guide component 11 for allowing the transverse rib body 7 to slide to the top of the lower welding block 501, and a limiting component 10 is provided above the lower welding block 501 for intercepting and fixing the transverse rib body 7, and the limiting component 10 includes a guide arm 1005 with an adjustable position and a diameter smaller than the longitudinal rib body 8, and the lowest point of the guide arm 1005 is adapted to the vertical surface where the welding block is located.

[0033] The straightening machine 3 is used to straighten the steel bars inside the coil 2, and its output end is in contact with the position of the conveying pulley 901. The conveying slider 901 can be driven by a motor. The positions of the upper welding block 502 and the lower welding block 501 correspond one-to-one with the positions of the longitudinal reinforcement body 8, ensuring that each welding point can be welded in one welding process to ensure the quality of the steel mesh. The position setting of the guide arm 1005 can be adjusted and replaced according to steel meshes of different models and sizes, so as to meet the interception and positioning requirements of transverse reinforcement bodies 7 of different sizes. The upper and lower rows of welding blocks are both closely attached, which can increase the welding range of the steel mesh, and the transverse reinforcement body 7 is set at the top, which can reduce the difficulty of controlling its position. If the transverse reinforcement body 7 is set at the bottom, the problem of high difficulty in positioning the transverse reinforcement body 7 may occur, affecting the welding efficiency.

[0034] An upper connecting block 13 is installed at the top end of the welding frame 5, and a lower supporting seat 12 is installed at the bottom end of the welding frame 5. The upper welding block 502 and the lower welding block 501 are both connected to a telescopic cylinder 504 for controlling the synchronous clamping of the two. One side of the telescopic cylinder 504 is connected to a gas delivery pipeline 503. The upper welding block 502 is detachably installed on the bottom end of the upper connecting block 13 through the telescopic cylinder 504, and the lower welding block 501 is detachably installed on the top end of the lower supporting seat 12 through the telescopic cylinder 504.

[0035] The upper welding block 502 and the lower welding block 501 both use contact heating to weld the steel mesh. Therefore, special attention should be paid to avoiding contact between the guide component 11 and the limit component 10 and the welding block during processing. The key material of the guide component 11 and the limit component 10 can be changed to a material with a high melting point and good thermal stability, such as refractory metals such as tungsten and molybdenum, or some high-temperature ceramic materials.

[0036] The limiting assembly 10 includes a synchronous push rod 1012 installed on one side of the lower support seat 12, and a plurality of ejection assemblies 1001 for pushing the synchronous push rod 1012 up and down are arranged at the bottom end of the synchronous push rod 1012, and a plurality of first sliders 1002 are arranged on one side of the synchronous push rod 1012, and the first sliders 1002 can slide longitudinally along the lower support seat 12.

[0037] The lower support seat 12 is provided to control the synchronous push-out of the synchronous push rod 1012, thereby realizing the synchronous descent of multiple synchronous guide arms 1005, making it easier for the CNC mesh pulling mechanism 1 to pull out the steel mesh and ensuring the smoothness of the steel mesh processing.

[0038] A slide rail 1004 is provided on the upper surface of the synchronous push rod 1012, and a plurality of position-adjustable limit blocks 1003 are installed through the slide rail 1004. A second slider 1006 that slides inside the slide rail 1004 is provided at the bottom end of the limit block 1003, and mounting holes 1007 are provided on both side walls of the limit block 1003 for detachably mounting the limit block 1003 on the top of the synchronous push rod 1012.

[0039] The setting of the limit block 1003 and the mounting hole 1007 is used to achieve that when facing different types of steel meshes, the position of the limit block 1003 can be modified to avoid the guide arm 1005 from contacting the lower welding block 501 during the welding process, thereby ensuring that the welding effect is not affected.

[0040] The top of the limit block 1003 is provided with a guide arm 1005 that can slide in the longitudinal direction. The limit block 1003 is symmetrically arranged on both sides of the lower welding block 501. The middle part of the guide arm 1005 is concave, and the two sides of the concave surface of the guide arm 1005 are inclined surfaces. Both end surfaces of the guide arm 1005 are longitudinally inserted into the limit blocks 1003 on both sides of the lower welding block 501. Rectangular grooves 1011 are provided on both side walls of the limit block 1003. A push block 1010 for guiding and limiting is provided at the bottom end of the guide arm 1005. The bottom ends of the plurality of push blocks 1010 are commonly connected to a synchronous pressing plate 1009 that simultaneously penetrates the plurality of rectangular grooves 1011. A return spring 1008 is provided at the bottom end of the synchronous pressing plate 1009 inside the limit block 1003. When the guide arm 1005 does not carry the transverse rib body 7, the return spring 1008 can push the synchronous pressing plate 1009 against the top of the rectangular groove 1011; when the guide arm 1005 carries the transverse rib body 7, the synchronous pressing plate 1009 is forced to compress the return spring 1008, and the synchronous pressing plate 1009 slides slightly downward along the rectangular groove 1011 to reduce the impact of the falling of the transverse rib body 7; when the welding block moves for welding, the guide arm 1005 is located between the two welding blocks, and the guide arm 1005 The diameter is smaller than the diameter of the longitudinal reinforcement body 8. The bottom end of the guide arm 1005 will not interfere with the lower welding block 501 during the welding clamping process, and the synchronous pressing plate 1009 is in the middle and lower part of the rectangular groove 1011 at this time; when the steel mesh needs to be pulled after welding, the bending mechanism 6 located at both ends will press the synchronous pressing plate 1009 to avoid the interference of the guide arm 1005 on the movement of the transverse reinforcement body 7. At this time, the synchronous pressing plate 1009 is located at the bottom end of the rectangular groove 1011.

[0041] The reset spring 1008 is used to reset the synchronous pressing plate 1009 in time after the movement of the steel mesh is completed, so that the guide arm 1005 can intercept the transverse reinforcement body 7 in time. The concave setting of the guide arm 1005 can make the transverse reinforcement body 7 be vertically set at the top of the longitudinal reinforcement body 8 under the action of multiple inclined surfaces, so as to realize the guiding positioning of the transverse reinforcement body 7. In the process of welding the transverse reinforcement body 7 and the longitudinal reinforcement body 8 by the upper welding block 502 and the lower welding block 501, the diameter of the guide arm 1005 is smaller than the diameter of the longitudinal reinforcement body 8. During the welding process, the guide arm 1005 cannot be contacted, so that multiple limit assemblies 10 are installed on both sides of the lower welding block 501. The position of the limit assemblies 10 can be adjusted according to the different sizes of the steel mesh, so as to adapt to various types of steel mesh. The guide arm 1005 is detachably installed and can be replaced according to the longitudinal reinforcement bodies 8 of different sizes, thereby improving the applicability of the device. In the no-load state, the synchronous pressing plate 1009 is tightly pressed against the moment. The top of the rectangular groove 1011 maintains the stability of the mechanical structure and the initial position of the guide arm 1005. In the process of carrying the transverse reinforcement body 7, the setting of multiple return springs 1008 can effectively reduce the impact of the transverse reinforcement body 7 when it falls, protect the components from damage, and speed up the positioning speed of the transverse reinforcement body 7; in the process of welding and clamping, since the diameter of the guide arm 1005 is smaller than the diameter of the longitudinal reinforcement body 8, the guide arm 1005 will not interfere with the lower welding block 501 during the welding and clamping process, and the inclined surfaces at both ends of the guide arm 1005 will not interfere with the upper welding block 502, thereby ensuring the smooth progress of welding; after welding, when it is necessary to pull the steel mesh for subsequent operations, the bending mechanisms 6 at both ends will press the synchronous pressing plate 1009, so that the synchronous pressing plate 1009 further slides down to the bottom of the rectangular groove 1011, thereby ensuring that the guide arm 1005 will not interfere with it during the movement of the transverse reinforcement body 7. This design improves the flexibility and efficiency of the movement of the steel mesh.

[0042] The transverse reinforcement conveying frame 9 is provided with a corresponding conveying pulley 901 at the reinforcement conveying position of the straightening machine 3, and an inclined guide slope 910 for the reinforcement to slide down is provided inside the transverse reinforcement conveying frame 9. A rectangular mounting frame 902 is detachably installed at the bottom end of the transverse reinforcement conveying frame 9, and a rotatable synchronous belt 903 is provided inside the rectangular mounting frame 902. A plurality of push plates 906 for conveying the transverse reinforcement body 7 are installed on the outer surface of the synchronous belt 903. A rotating motor 904 is also installed at the bottom end of the transverse reinforcement conveying frame 9, and a transmission shaft 905 is connected to the output end of the rotating motor 904, and the transmission shaft 905 can drive the synchronous belt 903 to rotate synchronously.

[0043] The inclined guide slope 910 is used to transport the transverse rib body 7 to the top of the synchronous belt 903. The top of the synchronous belt 903 is flush with the inner surface of the transverse rib conveying frame 9, ensuring that the transverse rib body 7 can be transported to the specified position through the push plate 906.

[0044] The top of the transverse rib conveying frame 9 is provided with an intercepting plate 907 for controlling the falling of the transverse rib body 7, and the bottom end of the intercepting plate 907 extends to the interior of the transverse rib conveying frame 9. The top of the transverse rib conveying frame 9 is provided with a first telescopic component 911 for controlling the lifting and lowering of the intercepting plate 907. The bottom end of the transverse rib conveying frame 9 is also provided with a blanking plate 909 for controlling the pushing out of the transverse rib body 7. The blanking plate 909 is located on one side of the intercepting plate 907, and the bottom end of the blanking plate 909 is rotatably connected to the second telescopic component 908 installed on the bottom end of the transverse rib conveying frame 9.

[0045] A storage device for the transverse rib body 7 can also be set inside the transverse rib conveying frame 9 to store the processed transverse rib body 7 and push it out one by one according to usage requirements to avoid multiple transverse rib bodies 7 falling at the same time and affecting product welding. The intercepting plate 907 and the unloading plate 909 are both used to control the falling time interval and falling speed of the transverse rib body 7, so as to ensure the normal use of the device. The rectangular grooves 1011 opened on both sides of the limit block 1003 can avoid the synchronous pressing plate 1009 from changing its position when adjusting the position of the limit assembly 10, so as to facilitate the adjustment of the height position of the guide arm 1005 by sliding the longitudinal lower pressure plate 602 downward.

[0046] The guide assembly 11 includes an upper guide rod 1101 and a lower guide rod 1102 . Multiple guide assemblies 11 can be detachably installed on the end surface of the cross-rib conveying frame 9 . The number and position of the upper guide rod 1101 and the lower guide rod 1102 are compatible with the guide arm 1005 .

[0047] The position of the guide component 11 can be adjusted to meet the size requirements of multiple groups of models. At the same time, a limit device with a guiding function can be added inside the guide component 11 to avoid excessive tilting during the descent of the transverse reinforcement body 7, which may lead to a decrease in the welding effect of the steel mesh, thereby ensuring construction efficiency.

[0048] The bending mechanism 6 includes a bending component 601 for bending the transverse rib body 7, one side of the bending component 601 is provided with a transverse telescopic component for driving the bending component 601 to slide back and forth transversely, the bottom end of the bending component 601 is provided with a longitudinal lower pressure plate 602, the bottom end of the longitudinal lower pressure plate 602 is provided with a longitudinal telescopic component 603 for driving the bending component 601 to slide longitudinally, and the two ends of the synchronous pressing plate 1009 extend to the bottom end of the longitudinal lower pressure plate 602 respectively.

[0049] During the falling process of the transverse rib body 7, the bending assembly 601 is driven to retreat through the lateral telescopic assembly. When the transverse rib body 7 falls on the guide arm 1005, the bending assembly 601 is pushed forward so that the transverse rib body 7 is located within the working range of the bending assembly 601. During the welding process, the bending mechanism 6 bends the transverse rib body 7 through the bending assembly 601 to meet the processing requirements. When the welded mesh needs to be pulled out, the longitudinal lower pressure plate 602 is moved to press the synchronous pressing plate 1009 at the bottom of the longitudinal lower pressure plate 602, so that the guide arm 1005 moves downward to a position where it cannot interfere with the sliding of the mesh.

[0050] The present invention arranges the transverse reinforcement conveying frame 9 above the longitudinal reinforcement conveying frame 4. When the steel mesh needs to be processed, the longitudinal reinforcement conveying frame 4 pushes out the multiple longitudinal reinforcement bodies 8 synchronously. The transverse reinforcement conveying frame 9 passes the transverse reinforcement body 7 conveyed by the straightening machine 3 into the interior of the transverse reinforcement conveying frame 9 through the conveying pulley. The transverse reinforcement body 7 is conveyed by the synchronous belt 903 and the push plate 906. The transverse reinforcement body 7 slides to the top of the guide arm 1005 through the guide assembly 11. At this time, the lower welding block 501 and the upper welding block 502 are synchronously clamped to weld the transverse reinforcement body 7 and the longitudinal reinforcement body 8. The welded steel mesh is pulled out by the CNC mesh pulling mechanism 1 to facilitate the next step of welding, thereby achieving the completion of the same transverse reinforcement through a single welding. Welding work with multiple longitudinal reinforcements; a reset spring 1008 is provided at the end of the guide arm 1005. During the synchronous clamping and welding process of the lower welding block 501 and the upper welding block 502, the guide arm 1005 can be prevented from obstructing the welding of the transverse reinforcement body 7 and the longitudinal reinforcement body 8, and the bending of the transverse reinforcement body 7 or the guide arm 1005 can be avoided. When the CNC mesh drawing mechanism 1 pulls out the steel mesh, the protruding end of the guide arm 1005 will affect the pulling out of the steel mesh. The synchronous pressing plate 1009 is pressed down by the longitudinal lower pressure plate 602, so that the synchronous pressing plate 1009 presses multiple reset springs 1008 at the same time, driving the multiple guide arms 1005 to slide downward synchronously, thereby solving the problem that the protruding end of the guide arm 1005 affects the pulling out of the steel mesh.
