Description

Technical Field

[0001] The present invention relates to the technical field of ribbed steel production, and specifically to a production process for Nb-containing ribbed steel HRB400E. Background Art

[0002] Niobium-containing ribbed steel is a high-strength steel that optimizes mechanical properties and process performance by adding trace amounts of niobium. Its core advantages lie in the grain refinement and precipitation strengthening effects of niobium. Ribbed steel HRB400E is a hot-rolled ribbed steel bar, formerly known as grade III ribbed steel. Its standard yield strength value is 400 MPa, and "E" represents meeting the seismic performance requirements. The production process of ribbed steel includes blast furnace ironmaking, steelmaking decarbonization, continuous casting forming, rolling into finished products, thread forming, air cooling temperature control, fixed-length shearing, bundling and warehousing, etc.

[0003] The patent with the application number CN202223091441.6 mentions "a cutting device for ribbed steel production". In this patent, it is inserted into the first circular opening between the driving roller and the driven roller, thereby starting the second motor inside the second motor box. The driving end of the second motor drives the driving roller to rotate, which drives the driven roller to rotate, and thus realizes the automatic driving and transmission of ribbed steel. When the cutting is completed, the electric conveyor belt at the other end of the moving table is started, thereby realizing the automatic transmission and cutting of ribbed steel, as well as the automatic transmission after cutting, thus solving the problems of inconvenient cutting and collection.

[0004] However, when performing continuous production and segmentation processing on ribbed steel, it is generally directly processed by cold cutting without positioning and restricting the ribbed steel. As a result, it is prone to position inclination during cutting due to continuous conveying, leading to inclined cutting surfaces and dimensional deviations. Moreover, only through one-time cutting, the pressure on the cutting tool is increased, affecting the flatness and efficiency of cutting, resulting in the inability to quickly process the segmented cutting of ribbed steel and the inability to ensure dimensional unity.

[0046] Compared with the prior art, the beneficial effects of the present invention are:

[0047] 1. There are multiple limiting and cutting components. The correction electric slide rails drive the clamping moving plates, the piezoelectric push rods drive the clamping electromagnetic blocks to magnetically fix the deformed steel bars, and traction and movement are carried out on them to adjust the positions of the deformed steel bars. The clamping hydraulic cylinders and the clamping anti-sliding blocks are used to clamp and limit the deformed steel bars, realizing the uniform distribution and positioning support of the deformed steel bars. The flipping motor drives the flipping propulsion plate to rotate to be parallel to the propulsion integrated frame, and the propulsion electric slide rails drive the propulsion integrated frame and the flipping propulsion plate to push the deformed steel bars to move. The shaping hydraulic cylinders drive the cold rolling alignment frame and the cold rolling fixed wheels to fit to the side ends of the deformed steel bars, and the clamping hydraulic cylinders drive the clamping porous blocks to move downward, so that the deformed steel bars are sleeved inside the clamping porous blocks. The friction hydraulic cylinders drive the anti-sliding treatment pads to move downward to adjust the friction force, so that the deformed steel bars can be fully positioned during movement, avoiding position deviation and inclination during movement, resulting in the deformed steel bars gathering together and having large-scale dimensional position deviations, affecting the accuracy of subsequent cutting dimensions and cutting surfaces. Moreover, by adjusting the friction force and multi-stage clamping cooperation, the deformed steel bars can be steadily restricted during cutting, avoiding position deviation during cutting and further improving the accuracy of cutting and forming.

[0048] 2. The impact hydraulic cylinder drives the impact slitting knife to position and slit the deformed steel bar, achieving pre-cutting treatment. The cutting hydraulic cylinder drives the stamping cutting knife to perform secondary stamping and cutting on the deformed steel bar. With the cooperation of multi-stage cutting, the impact pressure caused by one-time cutting can be reduced during cutting, the flatness and efficiency of the cut surface can be improved, the pressure on the cutting tool can be reduced, the damage speed can be slowed down, and the service life of the cutting equipment can be extended. The external dimensions of the deformed steel bar are measured by a laser measuring instrument. The spring return rod drives the elastic limit plate and the fitting processing block to move, and the position of the fitting processing block is controlled by a reset electromagnet. The pressure sensor is squeezed by the deformed steel bar and the spring return rod to determine whether the shape of the deformed steel bar is uniform. The shaping hydraulic cylinder drives the cold rolling alignment frame and the cold rolling fixing wheel to perform cold rolling treatment on the deformed steel bar to correct its shape, ensuring the uniformity of the overall dimensions of the deformed steel bar and avoiding the occurrence of cutting misalignment and deviation due to large bending amplitude and uneven contact surface of the deformed steel bar during cutting, effectively ensuring the efficiency of segmented cutting production and the speed of cutting forming.

[0049] 3. The deformed steel bar is restricted by magnetic attraction lifting and moving traction, hydraulic clamping restrictions at both ends, alignment pressing and socketing restrictions, and friction adjustment restrictions. With the cooperation of multi-stage cutting treatment, multi-stage detection, and hydraulic cold rolling shaping, the overall uniformity of the deformed steel bar is ensured, effectively solving the problem in the prior art that the deformed steel bar is not positioned and restricted, resulting in position deviation and inclination during continuous conveying. Moreover, with multi-stage cutting, the flatness of the cut surface of the deformed steel bar and the accuracy of the cutting size are effectively ensured, guaranteeing the unity of the overall dimensions and the efficiency of cutting production.

[0050] 4. An adjustment traction assembly is provided. The moving hydraulic cylinder pushes the processing linkage block to move with the rolling assistance of the moving cooperation wheel. The lifting hydraulic cylinder drives the lifting support frame to lift and lower to adjust the position of the lifting support frame. The distance between multiple groups of components is adjusted according to the required length. The processing motor drives the processing blocking plate to rotate to squeeze and fit one end of the deformed steel bar to achieve the positioning and support of the deformed steel bar. The integration hydraulic cylinder drives the integration porous block to lift and lower, and the lower piezoelectric push rod drives the lower anti-slip pad to lift and lower. With the cooperation of the lifting support frame, the deformed steel bar is supported for weight bearing, controlling the cutting length of the deformed steel bar during cutting. At the same time, segmented support can be carried out during cutting to avoid the occurrence of bending and sinking of the deformed steel bar due to too long support spacing, resulting in large deviations in cutting dimensions and affecting product quality. At the same time, through spacing support, it is convenient for external lifting equipment to pick up materials, improving the operation speed and convenience, and ensuring the efficiency of segmented cutting production of the deformed steel bar.

[0051] In summary, through the cooperation of the multi-limit cutting component and the adjustment traction component, the cutting position and cutting size of the ribbed steel are adjusted and corrected by using the multi-section adjustment components, and the multi-section extrusion clamping components are mutually limited to realize the stable support and smooth cutting of the ribbed steel, reduce the dimensional deviation and cutting deviation caused by the inclination and bending of the ribbed steel, and improve the quality of the product and the cutting efficiency.

[0101] For the stable operation of the equipment, the input ends of the hollow electromagnetic sleeve 301, the mobile hydraulic cylinder 307, the lifting hydraulic cylinder 309, the integrated hydraulic cylinder 311, the lower piezoelectric push rod 313, the clamping electric slide rail 315, and the processing motor 317 are all electrically connected to the output end of an external controller.

[0102] The working principle and usage process of the present invention: When pulling and cutting the ribbed steel, the combined limiting column 302 is inserted into the inner side of the hollow electromagnetic sleeve 301, and the side end of the collection positioning box 303 is connected to the side end of the integral support limiting frame 1. At this time, the hollow electromagnetic sleeve 301 magnetically fixes the combined limiting column 302, thereby clamping and fixing the collection positioning box 303. The staff places the steel bars on the inner side of the multi-limiting cooperation frame 202 at the top of the integral support limiting frame 1 through an external transportation device. At this time, the piezoelectric push rod 205 drives the piezoelectric electromagnet 206 to move downward, magnetically connecting the piezoelectric electromagnet 206 with the ribbed steel. After magnetically fixing the ribbed steel, the piezoelectric push rod 205 drives the piezoelectric electromagnet 206 and the ribbed steel to rise. The correction electric slide rail 203 drives the clamping moving plate 204 and the piezoelectric push rod 205 to move. At this time, the piezoelectric electromagnet 206 and the ribbed steel are synchronously driven to move, and multiple ribbed steels are gradually and evenly placed at each corresponding feeding position. At this time, the clamping hydraulic cylinder 207 near the piezoelectric electromagnet 206 drives the clamping anti-sliding block 208 to move, and the clamping anti-sliding blocks 208 at the top and bottom are moved to fit against the side end of the ribbed steel, realizing the fixation of the ribbed steel after being hoisted and moved and placed, ensuring its placement stability, realizing the position correction processing of the ribbed steel, and avoiding the situation that the cutting is inclined and offset due to the uneven dispersion of the ribbed steel position during the cutting process, affecting the cutting surface and the sectional dimension of the ribbed steel;

[0103] After the alignment restriction is completed, the flipping motor 228 drives the flipping propulsion plate 229 to rotate along the propulsion integration frame 227, and one end of the flipping propulsion plate 229 is fitted with one end of the deformed steel bar. After the fitting is completed, at this time, the clamping hydraulic cylinder 207 drives the clamping anti-sliding block 208 to loosen the deformed steel bar. At this time, the propulsion electric slide rail 226 drives the propulsion integration frame 227 and the flipping propulsion plate 229 to push the deformed steel bar to move along the multi-limit fitting frame 202, and gradually push the deformed steel bar to the cutting position. During the propulsion process, the laser measuring instrument 225 measures the external dimensions of the deformed steel bar, and the spring return rod 212 drives the elastic limit plate 213 and the fitting processing block 214 to move, and the pressure sensor 215 on the side end of the fitting processing block 214 is fitted to the side end of the deformed steel bar. During the continuous movement of the deformed steel bar, the shaping hydraulic cylinder 209 drives the cold rolling alignment frame 210 to move along the multi-limit fitting frame 202, and the side ends of multiple groups of cold rolling fixing wheels 211 are fitted to the side end of the deformed steel bar. By adjusting the positions of the cold rolling fixing wheels 211, the adjustment of different positions and different dimensions of the deformed steel bar is realized, a small cooling correction is realized, the shape of the deformed steel bar is shaped and repaired, the accuracy of the dimensions of the deformed steel bar is ensured, and through continuous moving and pressing treatment, the shaping cold rolling treatment is realized, and the quality of the finished product and the uniformity of the dimensions are improved;

[0104] After the irregular part at the front end of the deformed steel bar is pushed out of the cutting position, the irregular section enters the inner side of the integral limit operation frame 201. At this time, the clamping hydraulic cylinder 207 is used to drive the clamping anti-sliding block 208 to move again, and the clamping anti-sliding block 208 is used for clamping in opposite directions. The clamping hydraulic cylinder 221 drives the clamping porous block 222 to move downward, and the friction hydraulic cylinder 223 drives the anti-sliding treatment pad 224 to move downward, and the bottom of the side end of the anti-sliding treatment pad 224 is fitted to the side end of the deformed steel bar to perform a pressing and anti-sliding treatment on the deformed steel bar and fix and prevent the deformed steel bar from sliding. At this time, the impact hydraulic cylinder 217 drives the impact cutting knife 218 to move downward to gradually perform a shallow cutting treatment on the deformed steel bar and perform a pre-cutting treatment on the deformed steel bar. After the pre-treatment is completed, the cut is advanced to the position of the stamping cutting knife 220. After the advancement is completed, the cutting hydraulic cylinder 219 drives the stamping cutting knife 220 to perform another stamping cut on the pre-cut deformed steel bar along the integral limit operation frame 201. Through multi-stage cutting, the cutting position of the deformed steel bar is corrected, and through multi-stage pre-cutting and cooperation, the correction electric slide rail 203 drives the clamping moving plate 204 and the counter-pressure electromagnet 206 to traction and pull the deformed steel bar to move for secondary position correction. After the position correction is completed, the cutting treatment is performed again to ensure the flatness of the cut surface and the accuracy of the cutting dimensions;

[0105] After the irregular section of the deformed steel bar is cut, the unfolding motor 232 drives the unfolding outer push plate 233 to rotate along the whole-limit operation frame 201, opening the whole-limit operation frame 201. The outer-row electric slide rail 234 drives the outer push plate 235 to move, and the outer push plate 235 is used to push the deformed steel bar to move along the whole-limit operation frame 201, pushing the irregular deformed steel bar into the inner side of the collection positioning box 303 to achieve waste recycling. After the discharging is completed, the unfolding motor 232 drives the unfolding outer push plate 233 to reset, closing the whole-limit operation frame 201. When small-section cutting is required, the collection positioning box 303 is replaced. At this time, the blocking motor 230 drives the blocking closing plate 231 to flip, rotating and closing the whole-limit operation frame 201. At this time, the deformed steel bar is again pushed by the pushing and integrating frame 227 and the flipping push plate 229 so that one end of the deformed steel bar fits against the position of the blocking closing plate 231. At this time, the impact cutting knife 218 and the stamping cutting knife 220 are used to cut the deformed steel bar, dividing the deformed steel bar into small sections. After the division is completed, the unfolding motor 232 drives the unfolding outer push plate 233 to rotate again, and the outer-row electric slide rail 234 drives the outer push plate 235 to push the cut and formed deformed steel bar into the inner side of the collection positioning box 303 to achieve the material collection process;

[0106] When performing the cutting and segmentation of long ribbed steel bars, the moving hydraulic cylinder 307 is used to push the processing linkage block 304. Under the rolling action of the moving mating wheel 308, the processing linkage block 304 moves. At this time, the sliding positioning plate 305 moves along the integral support limiting frame 1 to adjust the distance between the processing linkage block 304 and the integral support limiting frame 1. The moving hydraulic cylinder 307 pushes the second processing linkage block 304 to move with the assistance of the moving mating wheel 308 to adjust the distance between the two processing linkage blocks 304. At this time, the sliding positioning plate 305 and the support sliding frame 306 are slidably positioned and supported, and the processing linkage block 304 is positioned and restricted by the sliding positioning plate 305 and the support sliding frame 306 to ensure the stability of the overall support. According to the required length, the processing motor 317 drives the processing blocking plate 318 to rotate and rise, and the propulsion integration frame 227 and the flipping propulsion plate 229 are used to push the ribbed steel bar to move and fit against the side end of the processing blocking plate 318. At this time, the lifting hydraulic cylinder 309 drives the lifting support frame 310 to rise, so that the ribbed steel bar is accurately placed at the inner bottom end of the lifting support frame 310. The integration hydraulic cylinder 311 drives the integration porous block 312 to move down and fit against the inner bottom end of the lifting support frame 310. The downward pressure electric push rod 313 drives the downward pressure anti-slip pad 314 to move down along the integration porous block 312, and the side end of the downward pressure anti-slip pad 314 is fitted against the side end of the ribbed steel bar to perform the clamping and anti-slip treatment on the ribbed steel bar. When it moves to the required length, the impact hydraulic cylinder 217, the impact cutting knife 218, the cutting hydraulic cylinder 219, and the stamping cutting knife 220 perform stamping and cutting on the ribbed steel bar to achieve the segmentation treatment of the ribbed steel bar. After the cutting is completed, the integration hydraulic cylinder 311 drives the integration porous block 312 to rise, and the clamping electric slide rail 315 drives the clamping treatment plate 316 to move along the lifting support frame 310 to perform the integration treatment on the ribbed steel bar. At this time, multiple ribbed steel bars are bundled and packed by an external packing device, and are hoisted and moved in cooperation with a hoisting device to achieve the stable cutting and continuous production treatment of the ribbed steel bar.
