Description

Technical Field

[0001] The present invention relates to the technical field of steel bar processing, and specifically relates to a straightening device and method for steel bar processing. Background Technique

[0002] Steel bars are an important material commonly used in construction projects, mainly used to enhance the tensile strength of concrete to improve the bearing capacity and durability of the structure. When steel bars are specifically used, they are mostly used in a bent form. When they are recycled later, it is necessary to straighten the waste recycled steel bars;

[0003] Traditional straightening of waste recycled steel bars mostly directly transfers the coiled steel bars to a straightening device with staggeredly distributed straightening wheels for straightening. However, since the bent state of the waste recycled steel bars is directly put into the straightening device, they will still be in a bent state after straightening, and multiple straightening operations are required to completely straighten the steel bars. Moreover, the outer diameter sizes of the recycled steel bars are different, and it is necessary to adjust the spacing of the straightening wheels for adaptation, which affects the overall straightening processing efficiency of the steel bars. Secondly, the surfaces of the waste recycled steel bars are mostly rusty, and separate rust removal processing is required after straightening processing, which affects the overall straightening processing efficiency of the steel bars again. For this reason, we propose a straightening device and method for steel bar processing to solve the above problems. Summary of the Invention

The driving end of the second linear electric rail is fixedly installed with a second support. The top of the second support is fixedly installed with an L-shaped support.

The structure of the third driving assembly is the same as that of the first driving assembly. The third driving assembly is fixedly installed on the L-shaped support through two driving supports.

[0017] A method for using a straightening device for steel bar processing includes the following steps:

[0018] Step 1: Connect the end of the connector to the output port of the cleaning agent output system. In the initial state, the transmission rack and the driving gear are engaged. Subsequently, according to the outer diameter of the waste recycled steel bar, select a feeding through groove with an appropriate aperture size. By controlling the opening of the first linear electric rail to drive the primary straightening assembly to move horizontally, flexibly adjust the positions of the plurality of feeding through grooves, so that the feeding through groove with the corresponding aperture size is horizontally corresponding to the position of the feeding pipe.

[0019] While the primary straightening outer frame horizontally moves to adjust the positions of the plurality of feeding through grooves, through the connection of the auxiliary seat and the telescopic cylinder, the transmission rack is driven to move synchronously. The transmission rack drives the two driving gears to rotate synchronously, and then controls the two co-driven shaft rods on both sides and the plurality of worm gears on the same side to rotate synchronously, so as to control the corresponding worm wheels and adjusting screws to rotate synchronously. Since the adjusting screws are threadedly installed in the corresponding clamping sliding sleeves, the first straightening inclined rollers and the second straightening inclined rollers on both sides are driven to move synchronously towards each other, and the distance between the first straightening inclined rollers and the second straightening inclined rollers is synchronously reduced to adapt to the secondary straightening operation of steel bars with different aperture sizes.

[0020] Subsequently, control the opening of the telescopic cylinder to drive the transmission rack to move horizontally, so that the transmission rack can be separated from the driving gear.

[0021] Step 2: Insert the waste recycled steel bar into the feeding through groove with the corresponding aperture size, then pass through between the two driving rollers of the driving members at the corresponding positions in the first driving assembly and the second driving assembly, and pass through between the straightening rollers in the primary straightening bottom frame and the straightening rollers in the primary straightening top frame at the corresponding positions in the primary straightening member. By controlling the opening of the first motors in the first driving assembly and the second driving assembly, and cooperating with the meshing connection of the two transmission gears, drive the two driving rollers vertically corresponding to rotate synchronously in opposite directions, control the steel bar placed between the two driving rollers to be automatically transmitted, and while the steel bar is automatically transmitted, cooperate with the misaligned straightening rollers to perform automatic primary straightening operations.

[0022] Step 3: After the primary straightening operation of the steel bars is completed, they are immediately introduced into the secondary outer frame through the feed pipe and pass through between multiple first straightening inclined rollers and second straightening inclined rollers. The steel bars after primary straightening are in contact with the outer walls of the first straightening inclined rollers and the second straightening inclined rollers;

[0023] Meanwhile, control the second motor to drive the transverse shaft to rotate. With the transmission of the first sprocket, the second sprocket and the transmission chain, control the feed pipe, the secondary outer frame, multiple first straightening inclined rollers, second straightening inclined rollers and the cleaning brush to rotate at high speed, and cooperate with the automatic transmission of the steel bars after primary straightening in the secondary outer frame. Multiple first straightening inclined rollers and second straightening inclined rollers perform secondary straightening on the steel bars;

[0024] And at the same time, control the opening of the cleaning agent output system. The cleaning agent is introduced into multiple liquid spraying frames through the connector, the inner ring cylinder, the outer ring cylinder, the connecting pipe, the liquid guiding main pipe and multiple liquid guiding branch pipes, and is evenly sprayed on the surface of the steel bars through multiple cleaning spray holes. With the high-speed rotation of the cleaning brush, the steel bars are synchronously cleaned;

[0025] Step 4: After the secondary straightening of the steel bars, they pass through the secondary outer frame and are placed between two driving rollers of the driving member at the corresponding position in the third driving assembly. Control the two driving rollers vertically corresponding in the third driving assembly to rotate synchronously in opposite directions, and automatically pull out the steel bars, facilitating the automatic discharging of the steel bars after straightening.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By setting the primary straightening mechanism and cooperating with the secondary straightening mechanism, it is possible to automatically transmit the recycled steel bars, and at the same time, cooperate with the misaligned straightening rollers to perform automatic primary straightening operations, and use multiple first straightening inclined rollers and second straightening inclined rollers to perform secondary straightening on the steel bars, improving the straightening effect of the steel bars. At the same time, with the high-speed rotation of the cleaning brush, the steel bars are synchronously cleaned, increasing the functionality of the entire equipment and improving the overall processing effect of the steel bars.

[0028] 2. By setting the primary straightening mechanism and cooperating with the secondary straightening mechanism, flexibly adjust the positions of multiple feeding through slots, and synchronously and automatically control the spacing between the first straightening inclined rollers and the second straightening inclined rollers to adapt to the straightening operations of steel bars with different hole diameters, thereby improving the flexibility of the entire equipment.

[0029] 3. By setting the final pulling mechanism, the steel bars are automatically pulled out, facilitating the automatic discharging of the steel bars after straightening, and further improving the use effect of the entire straightening equipment. Description of the Drawings

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment: As Figure 1-11 shown, the present invention provides a straightening device for steel bar processing, including an equipment base 1. One side of the top end of the equipment base 1 is fixedly installed with an initial alignment mechanism 2, and the other side of the top end of the equipment base 1 far from the initial alignment mechanism 2 is fixedly installed with a final pulling mechanism 3. A secondary alignment mechanism 4 is arranged between the initial alignment mechanism 2 and the final pulling mechanism 3.

[0045] The initial alignment mechanism 2 includes a first linear electric rail 21. The first linear electric rail 21 is fixedly installed on one side of the top end of the equipment base 1. The driving end of the first linear electric rail 21 is fixedly installed with a first support 22, and the top end of the first support 22 is fixedly installed with an initial alignment assembly. Control the first linear electric rail 21 to drive the initial alignment assembly to move horizontally;

[0046] The initial alignment component includes an initial alignment outer frame 23, which is fixedly installed at the top of the first support 22. A plurality of uniformly distributed feeding through slots 231 are formed in the initial alignment outer frame 23, and the aperture sizes of the plurality of feeding through slots 231 gradually decrease. One side of the inner wall of the initial alignment outer frame 23 is provided with a first driving component 24, and the other side of the inner wall of the initial alignment outer frame 23 away from the first driving component 24 is provided with a second driving component 25. An initial alignment piece 26 is arranged between the first driving component 24 and the second driving component 25. By driving the initial alignment component to move horizontally, the positions of the plurality of feeding through slots 231 can be flexibly adjusted, facilitating the initial alignment operation of waste recycling steel bars with different outer diameters, thereby improving the flexibility of the entire equipment;

[0047] The first driving component 24 includes a plurality of driving members corresponding to the feeding through slots 231. Each driving member includes two driving supports 241 symmetrically distributed up and down. The driving member is fixedly installed on the inner wall of the initial alignment outer frame 23 through the two driving supports 241. Driving rollers 242 are rotatably installed at the opposite ends of the driving supports 241. Transmission gears 243 are fixedly installed at one ends of the driving rollers 242. The two transmission gears 243 are meshed and connected. A first motor 244 is fixedly installed on the outside of one of the driving supports 241. The driving end of the first motor 244 is fixedly installed with the shaft end of the corresponding driving roller 242. During use, by controlling the first motor 244 to start, and cooperating with the meshing connection of the two transmission gears 243, the two vertically corresponding driving rollers 242 are driven to rotate synchronously and in opposite directions, thereby automatically transporting the steel bars placed between the two driving rollers 242. The distances between the two driving rollers 242 in the plurality of driving members gradually decrease, and respectively correspond to the feeding through slots 231 with different aperture sizes one by one;

[0048] The structure of the second driving component 25 is the same as that of the first driving component 24. The two driving supports 241 of the second driving component 25 are fixedly installed on the inner wall of the initial alignment outer frame 23, and the second driving component 25 and the first driving component 24 are in a symmetrical distribution structure;

[0049] The first calibration component 26 includes a plurality of first calibration groups corresponding to the feeding through slots 231. Each first calibration group includes a first calibration bottom frame 261 and a first calibration top frame 262. The first calibration groups are fixedly installed on the lower surface and the upper surface of the inner wall of the first calibration outer frame 23 through the first calibration bottom frame 261 and the first calibration top frame 262 respectively. Straightening rollers 263 are rotatably installed at the opposite ends of the first calibration bottom frame 261 and the first calibration top frame 262. The straightening rollers 263 in the first calibration bottom frame 261 are staggeredly distributed with the straightening rollers 263 in the first calibration top frame 262. The spacing between the straightening rollers 263 on the first calibration bottom frame 261 and the straightening rollers 263 on the first calibration top frame 262 in the plurality of first calibration groups gradually decreases, corresponding one by one to the feeding through slots 231 with different aperture sizes. During use, the recycled steel bars are inserted into the feeding through slots 231 with corresponding aperture sizes, then pass through between the two driving rollers 242 of the driving members at the corresponding positions in the first driving assembly 24 and the second driving assembly 25, and pass through between the straightening rollers 263 in the first calibration bottom frame 261 and the straightening rollers 263 in the first calibration top frame 262 at the corresponding positions in the first calibration component 26. By the synchronous reverse rotation of the two vertically corresponding driving rollers 242 in the first driving assembly 24 and the second driving assembly 25, the steel bars placed between the two driving rollers 242 are controlled to be automatically transported. While the steel bars are being automatically transported, automatic primary straightening operations are performed in cooperation with the staggeredly distributed straightening rollers 263.

[0050] The secondary calibration mechanism 4 includes two longitudinally rotating brackets 41 symmetrically distributed. The longitudinally rotating brackets 41 are fixedly installed at the top of the equipment base 1. Feeding pipes 42 are rotatably installed in the middle of the longitudinally rotating brackets 41. A secondary calibration outer frame 43 is fixedly installed between the two feeding pipes 42. A plurality of first straightening inclined rollers 44 are evenly distributed in the secondary calibration outer frame 43. A plurality of second straightening inclined rollers 45 are evenly distributed in the secondary calibration outer frame 43. The plurality of first straightening inclined rollers 44 and the plurality of second straightening inclined rollers 45 are staggeredly distributed. After the primary straightening operation of the steel bars is completed, they are then introduced into the secondary calibration outer frame 43 through the feeding pipes 42 and pass through between the plurality of first straightening inclined rollers 44 and the second straightening inclined rollers 45. The primarily straightened steel bars are in contact with the outer walls of the first straightening inclined rollers 44 and the second straightening inclined rollers 45.

[0051] Auxiliary frames 47 are fixedly installed at the side ends of the outer frames of the first straightening inclined rollers 44 and the second straightening inclined rollers 45. Mounting frames 471 are fixedly installed on the opposite sides of the auxiliary frames 47. Liquid spraying frames 472 are fixedly installed on the sides of the mounting frames 471 away from the auxiliary frames 47. Cleaning brushes 473 are fixedly installed on the sides of the liquid spraying frames 472 away from the mounting frames 471. A plurality of cleaning spray holes 4721 are evenly distributed on the side of the liquid spraying frame 472 close to the cleaning brush 473. The steel bars pass through between the cleaning brushes 473 on the plurality of liquid spraying frames 472 at the same time.

[0052] At the top of the two vertically rotating brackets 41, a driving horizontal shaft 48 is rotatably installed. At both ends of the driving horizontal shaft 48, first sprockets 481 are fixedly installed. Outside the feed pipe 42, second sprockets 482 corresponding to the first sprockets 481 are fixedly installed. Outside the first sprockets 481 and the second sprockets 482 corresponding vertically, drive chains 483 are meshed and connected. At the top of one of the vertically rotating brackets 41, a second motor 49 is fixedly installed. The driving end of the second motor 49 is fixedly installed with the shaft end of the driving horizontal shaft 48. By controlling the start of the second motor 49, the driving horizontal shaft 48 is controlled to rotate. With the transmission of the first sprockets 481, the second sprockets 482 and the drive chains 483, the feed pipe 42, the secondary outer frame 43, and multiple first straightening inclined rollers 44, second straightening inclined rollers 45 and cleaning brushes 473 are controlled to rotate at high speed. With the cooperation of the automatically transmitted steel bars after primary straightening in the secondary outer frame 43, the multiple first straightening inclined rollers 44 and second straightening inclined rollers 45 straighten the steel bars for the second time, improving the straightening effect of the steel bars.

[0053] On the opposite ends of the outer frames of the first straightening inclined roller 44 and the second straightening inclined roller 45, clamping and sliding sleeves 46 are fixedly installed. The clamping and sliding sleeves 46 are slidably clamped on the secondary outer frame 43. On one side of the secondary outer frame 43 close to the clamping and sliding sleeves 46, adjusting screws 461 are rotatably installed. The adjusting screws 461 are threadedly installed in the corresponding clamping and sliding sleeves 46. At the ends of the adjusting screws 461 away from the clamping and sliding sleeves 46, worm wheels 462 are fixedly installed. At the bottoms of the worm wheels 462, worm gears 463 are meshed and connected. The worm gears 463 are rotatably installed outside the secondary outer frame 43. Between the multiple worm gears 463 on the same side, a co-driving shaft rod 464 is fixedly installed. The co-driving shaft rod 464 is rotatably installed outside the secondary outer frame 43. At one end of the co-driving shaft rod 464, a driving gear 465 is fixedly installed. At the bottoms of the two driving gears 465, a transmission rack 466 is meshed and connected;

[0054] Outside the primary outer frame 23, two auxiliary seats 5 are fixedly installed. At the ends of the auxiliary seats 5, telescopic cylinders 51 are fixedly installed. The driving ends of the telescopic cylinders 51 are vertically installed with the transmission rack 466. The telescopic cylinders 51 drive the transmission rack 466 to move horizontally. By controlling the start of the telescopic cylinders 51 to drive the transmission rack 466 to move horizontally, the transmission rack 466 can be separated from the driving gear 465. On the contrary, by controlling the start of the telescopic cylinders 51 to drive the transmission rack 466 to move horizontally in the reverse direction, the transmission rack 466 can be meshed with the driving gear 465;

[0055] After meshing, while the initial calibration outer frame 23 moves horizontally to adjust the positions of multiple feeding slots 231, through the connection of the auxiliary seat 5 and the telescopic cylinder 51, the driving rack 466 is driven to move synchronously. The driving rack 466 drives the two driving gears 465 to rotate synchronously, and then controls the synchronous rotation of the co-driving shaft rods 464 on both sides and multiple worm gears 463 on the same side, thereby controlling the synchronous rotation of the corresponding worm wheels 462 and adjusting screws 461. Since the adjusting screw 461 is threadedly installed in the corresponding clamping and sliding sleeve 46, it drives the first straightening inclined rollers 44 and the second straightening inclined rollers 45 on both sides to move synchronously towards each other, synchronously reducing the distance between the first straightening inclined rollers 44 and the second straightening inclined rollers 45, so as to adapt to the secondary straightening operation of reinforcing bars with different hole diameters, further improving the flexibility of the entire device. On the contrary, when the driving rack 466 moves synchronously in the reverse direction, it can drive the first straightening inclined rollers 44 and the second straightening inclined rollers 45 on both sides to move synchronously away from each other, synchronously increasing the distance between the first straightening inclined rollers 44 and the second straightening inclined rollers 45, so as to adapt to the secondary straightening operation of reinforcing bars with different hole diameters.

[0056] Liquid guide branch pipes 474 are integrally formed at the top of each liquid spraying frame 472. A liquid guide main pipe 475 is fixedly installed at the top of multiple liquid spraying frames 472. An outer ring cylinder 476 is fixedly installed on the side of the secondary calibration outer frame 43 away from the driving rack 466. A connecting pipe 4761 corresponding to the liquid guide main pipe 475 is integrally formed on one side of the outer ring cylinder 476. The connecting pipe 4761 and the end of the liquid guide main pipe 475 are fixedly installed. A sealing rotating member 477 is provided on the side of the outer ring cylinder 476 away from the secondary calibration outer frame 43. An inner ring cylinder 478 is fixedly installed in the middle of the sealing rotating member 477. A connecting head 4781 is integrally formed at the top of the inner ring cylinder 478. A connecting seat 479 is fixedly installed on the outside of the connecting head 4781. The connecting seat 479 is fixedly installed on the outside of the longitudinal rotating bracket 41. When in use, the end of the connecting head 4781 is connected to the output port of the cleaning agent output system. While performing the secondary straightening operation on the reinforcing bar, the cleaning agent output system is controlled to be turned on.
