Description

Technical Field

[0001] This application relates to the technical field of steel bar processing, and in particular to a steel bar straightening and rust removal treatment device and a straightening and rust removal method. Background Art

[0002] Steel bar straightening and rust removal refers to the process of treating steel bars to make them straight and remove the surface rust. During transportation, storage, or processing, steel bars may become bent or deformed. Straightening involves applying external forces to the bent steel bars through specific equipment and processes to restore them to a straight state. Since steel bars are exposed to air for a long time, they are prone to chemical reactions with oxygen, moisture, etc., forming rust on the surface. Rust removal is to use physical or chemical methods to remove the rust layer on the surface of the steel bars to restore the original performance and appearance of the steel bars.

[0003] During the steel bar processing, straightening and rust removal are usually carried out as two independent processes, requiring different equipment and sites, which increases the handling times and time costs of the steel bars and is likely to cause secondary damage to the steel bars during handling. Since the straightening and rust removal equipment are independent of each other and there is a lack of an effective coordination mechanism between them, in actual operation, it is difficult to synchronously adjust the straightening and rust removal parameters according to the specific conditions of the steel bars. Therefore, it is necessary to provide a steel bar straightening and rust removal treatment device and a straightening and rust removal method that adopt an integrated straightening and rust removal processing technology, with the effects of integrating straightening and rust removal and adjustable straightening dimensions and rust removal radii.

[0012] By adopting the above technical solution, through the setting of the traction component, under the drive of the second servo motor and the combined use of the support wheel and the traction wheel, the steel bar is guided and transmitted, so that the steel bar still has a driving force to the right after leaving the inner cavity of the straightening box, and the steel bar part that leaves the inner cavity of the straightening box and belongs to the remaining rust removal part can be rust-removed.

[0013] Preferably, the extrusion component includes a secondary rotating rod. An extrusion wheel is fixedly connected to the surface of the secondary rotating rod. A support arm is fixedly connected to the top of the inner cavity of the traction box.

[0014] Preferably, torsion springs are sleeved on both the front side and the rear side of the surface of the swing frame. One end of the torsion spring is welded to the support arm, and the other end of the torsion spring is welded to the swing frame.

[0015] Preferably, a main rotating rod penetrates through the top of the rear side of the traction box and penetrates into the inner cavity of the support arm.

Transmission belt pulleys are fixedly connected to the front ends of the secondary rotating rod and the main rotating rod, and the two transmission belt pulleys are connected by a belt.

[0016] By adopting the above technical solution, through the setting of the extrusion component, under the combined use of the swing frame and the torsion spring, the secondary rotating rod and the extrusion wheel are elastically twisted, so that the extrusion wheel can actively move towards the surface of the steel bar and generate extrusion, enhancing the friction force between the surface of the steel bar and the surfaces of the traction wheel and the extrusion wheel. At the same time, under the transmission action of the main rotating rod, the transmission belt pulley and the synchronous gear, the extrusion wheel can move in the opposite direction to the traction wheel, thereby improving the transmission effect on the steel bar.

[0017] Preferably, anti - detachment guard plates are fixedly connected to both the front side and the rear side of the inner cavity of the straightening box, and an anti - detachment frame is welded to the left side of the two anti - detachment guard plates.

[0018] A steel bar straightening and rust - removing treatment device, and its method steps are as follows: Step 1: The user first rotates the threaded handle. Under the action of the threaded advancement of the threaded handle, the driven straightening wheel vertically slides up and down in the inner cavity of the straightening box, so as to adjust the distance between the driven straightening wheel and the driving straightening wheel, thereby adapting to the steel bar sizes of different diameters. Step 2: After the adjustment is completed, the user turns on the DC motor. The DC motor drives the driving rod located on the far right to rotate. At the same time, under the transmission action of the driving gear and the transmission gear, multiple driving rods rotate clockwise simultaneously. Then the user inserts the steel bar into the inner cavity of the anti - detachment frame, so that the surface of the steel bar contacts the driven straightening wheel and the driving straightening wheel. The steel bar is corrected and transmitted through the grooves on their surfaces. Under the extrusion and transmission action of multiple driven straightening wheels and driving straightening wheels, the originally bent steel bar is straightened. Step 3: After the right end of the steel bar extends out of the inner cavity of the straightening box and enters the inner cavity of the rotating disk, stop the DC motor, and turn on the cylinder and the first servo motor. The first servo motor starts and drives the rust - removing sand belt to rotate through the cooperation of three sand wheels. At this time, the cylinder pushes the sliding seat, so that the surface of the rust - removing sand belt contacts the surface of the steel bar, and the surface of the steel bar is polished and rust - removed. Step 4: Then turn on the DC motor again to continuously push the steel bar. The stepping motor starts at the same time and drives the driving gear to rotate. Since the driving gear and the toothed ring are in meshing transmission, the rotating disk rotates in the inner cavity of the fixed frame. The stepping motor starts to reverse after the rotating disk rotates 180 degrees to prevent damage to the air pipe of the cylinder and the power cord of the first servo motor. During the forward and reverse rotation of the rotating disk, the rust - removing sand belt comprehensively polishes and rust - removes the surface of the steel bar. Step 5: The straightened and rust - removed steel bar enters the inner cavity of the traction box and contacts the surface of the supporting wheel. At the same time, under the torsion of the torsion spring, the swing frame elastically advances downward and drives the pressing wheel to press on the surface of the steel bar. Step 6: At this time, the second servo motor is turned on and drives the traction rod to rotate. During the rotation of the traction rod, the traction wheel and two synchronous gears rotate. Under the transmission action of the two synchronous gears, the main rotating rod rotates. And under the transmission action of the two transmission belt pulleys, the auxiliary rotating rod and the pressing wheel rotate simultaneously, and the rotation direction is opposite to that of the traction wheel. Furthermore, the pressing wheel and the traction wheel play a role in transmitting the steel bar to the right side.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using the straightening box and the straightening assembly in combination, the steel bars are straightened and driven to the right. At the same time, through the combined use of the fixing frame, the rotating disk, the rust-removing assembly and the rotating assembly, the surface of the steel bars is comprehensively polished and rust-removed. Finally, under the extrusion and transmission action of the traction assembly, the extrusion assembly and the traction box, blanking is carried out, thus achieving the purpose of integrating straightening and rust-removing and making the straightening size and the rust-removing radius adjustable.

[0020] 2. Through the setting of the rotating assembly of the present invention, under the drive of the stepping motor and the combined use of the driving gear and the toothed ring, the rotating disk is driven to rotate, so that the rotating disk can rotate reciprocally in the inner cavity of the fixing frame. As a result, the rust-removing abrasive belt can move on the surface of the steel bars to comprehensively and thoroughly polish and rust-remove the steel bars. At the same time, through the combined use of the support, the guide wheel and the annular chute, the rotating disk is supported and guided, thereby improving the stability of the rotating disk during the rotation process.

[0021] 3. Through the setting of the traction assembly of the present invention, under the drive of the second servo motor and the combined use of the support wheel and the traction wheel, the steel bars are guided and driven, so that the steel bars still have a driving force to the right after leaving the inner cavity of the straightening box, enabling the part of the steel bars that has left the inner cavity of the straightening box and needs further rust-removing to be rust-removed.

[0022] 4. Through the setting of the extrusion assembly of the present invention, the combined use of the swing frame and the torsion spring elastically twists the secondary rotating rod and the extrusion wheel, enabling the extrusion wheel to actively move towards the surface of the steel bars and generate extrusion, enhancing the frictional force between the surface of the steel bars and the surfaces of the traction wheel and the extrusion wheel. At the same time, under the transmission action of the main rotating rod, the transmission belt pulley and the synchronous gear, the extrusion wheel can move in the opposite direction to the traction wheel, thereby improving the transmission effect on the steel bars.

[0040] Embodiment 4: Combined with Figures 1-7, the extrusion assembly 9 includes a secondary rotating rod 91, and an extrusion wheel 92 is fixedly connected to the surface of the secondary rotating rod 91. A support arm 93 is fixedly connected to the top of the inner cavity of the traction box 10. A swing frame 96 is rotatably connected to the inner cavity of the support arm 93. The swing frame 96 is rotatably connected to the surface of the main rotating rod 94. Torsion springs 97 are sleeved on the front side and the rear side of the surface of the swing frame 96.

At the same time, under the transmission action of the main rotating rod 94, the driving belt pulley 98 and the synchronous gear 95, the extrusion wheel 92 can move in the opposite direction to the traction wheel 82, thereby improving the transmission effect on the steel bar.

[0041] A steel bar straightening and rust removal treatment device, and its method steps are as follows: Step 1: The user first rotates the threaded handle 39. Under the action of the threaded advancement of the threaded handle 39, the driven straightening wheel 38 slides vertically up and down in the inner cavity of the straightening box 2, so as to adjust the distance between the driven straightening wheel 38 and the driving straightening wheel 32, so as to adapt to the steel bar sizes of different diameters; Step 2: After the adjustment is completed, the user turns on the DC motor 35. The DC motor 35 drives the driving rod 31 on the rightmost side to rotate. At the same time, under the transmission action of the driving gear 33 and the transmission gear 34, multiple driving rods 31 rotate clockwise at the same time. Subsequently, the user inserts the steel bar into the inner cavity of the anti - detachment frame 12, so that the surface of the steel bar contacts the driven straightening wheel 38 and the driving straightening wheel 32. The steel bar is straightened and transmitted through the grooves on their surfaces. Under the extrusion and transmission action of multiple driven straightening wheels 38 and driving straightening wheels 32, the originally bent steel bar is straightened; Step 3: After the right end of the steel bar extends out of the inner cavity of the straightening box 2 and enters the inner cavity of the rotating disk 5, stop the DC motor 35, and turn on the air cylinder 65 and the first servo motor 62. The first servo motor 62 starts and drives the rust - removal sand belt 64 to rotate through the cooperation of three sand belt wheels 63. At this time, the air cylinder 65 pushes the sliding seat 61, so that the surface of the rust - removal sand belt 64 contacts the surface of the steel bar and grinds and removes the rust on the surface of the steel bar; Step 4: Then, start the DC motor 35 again to continuously push the steel bar. At the same time, start the stepping motor 71 to drive the driving gear 72 to rotate. Since the driving gear 72 and the toothed ring 73 are in meshing transmission, the rotating disk 5 rotates in the inner cavity of the fixed frame 4. The stepping motor 71 starts to reverse after the rotating disk 5 rotates 180 degrees to prevent damage to the air pipe of the cylinder 65 and the power cord of the first servo motor 62. During the forward and reverse rotation of the rotating disk 5, the rust-removing abrasive belt 64 comprehensively grinds and removes rust from the surface of the steel bar; Step 5: The straightened and rust-removed steel bar enters the inner cavity of the traction box 10 and contacts the surface of the support wheel 84. At the same time, under the torsion of the torsion spring 97, the swing frame 96 elastically advances downward and drives the pressing wheel 92 to press against the surface of the steel bar; Step 6: At this time, start the second servo motor 83 to drive the traction rod 81 to rotate. During the rotation of the traction rod 81, the traction wheel 82 and the two synchronous gears 95 are driven to rotate. Under the driving action of the two synchronous gears 95, the main rotating rod 94 rotates. And under the driving action of the two transmission belt pulleys 98, the auxiliary rotating rod 91 and the pressing wheel 92 rotate simultaneously, and the rotation direction is opposite to that of the traction wheel 82. Thus, the pressing wheel 92 and the traction wheel 82 play a role in driving the steel bar to the right.

[0042] In summary, for the steel bar straightening and rust-removing treatment equipment and the straightening and rust-removing method, through the combined use of the straightening box 2 and the straightening assembly 3, the steel bar is straightened and driven to the right. At the same time, under the combined use of the fixed frame 4, the rotating disk 5, the rust-removing assembly 6 and the rotating assembly 7, the surface of the steel bar is comprehensively ground and rust-removed. Finally, under the extrusion and driving action of the traction assembly 8, the extrusion assembly 9 and the traction box 10, blanking is carried out, and the purposes of integrating straightening and rust-removing and adjusting the straightening size and rust-removing radius can be achieved.

[0043] The above are only the preferred embodiments of the present application and are not used to limit the present application.

10. A straightening and rust removal method for a steel bar straightening and rust removal treatment device, which is applied to the steel bar straightening and rust removal treatment device according to claim 9, characterized in that: The method steps are as follows: Step 1: The user first rotates the threaded handle (39), and under the action of the threaded advancement of the threaded handle (39), the driven straightening wheel (38) slides vertically up and down in the inner cavity of the straightening box (2), so that the distance between the driven straightening wheel (38) and the active straightening wheel (32) can be adjusted to adapt to the sizes of steel bars with different diameters; Step 2: After the adjustment is completed, the user turns on the DC motor (35), and the DC motor (35) drives the driving rod (31) located on the far right to rotate. At the same time, under the transmission action of the driving gear (33) and the transmission gear (34), the multiple driving rods (31) rotate clockwise at the same time. Then, the user inserts the steel bar into the inner cavity of the anti-slip frame (12), so that the surface of the steel bar contacts the driven straightening wheel (38) and the active straightening wheel (32), and the steel bar is straightened and driven through the grooves on the surfaces of the two. Under the extrusion transmission action of the multiple driven straightening wheels (38) and the active straightening wheel (32), the originally bent steel bar is straightened; Step 3: After the right end of the steel bar extends out from the inner cavity of the straightening box (2) and enters the inner cavity of the rotating disk (5), the DC motor (35) is stopped, and the cylinder (65) and the first servo motor (62) are turned on. The first servo motor (62) is started and the rust-removing sanding belt (64) is driven to rotate by the coordinated use of the three sanding belt wheels (63). At this time, the cylinder (65) pushes the slide seat (61) so that the surface of the rust-removing sanding belt (64) comes into contact with the surface of the steel bar, and the surface of the steel bar is polished and rust-removed. Step 4: Then, the DC motor (35) is turned on again to continuously push the steel bar, and the stepper motor (71) is started at the same time to drive the driving gear (72) to rotate. Since the driving gear (72) and the gear ring (73) are in a meshing transmission state, the rotating disk (5) rotates in the inner cavity of the fixed frame (4). The stepper motor (71) starts to reverse after the rotating disk (5) rotates 180 degrees to prevent damage to the air pipe of the cylinder (65) and the power cord of the first servo motor (62). During the forward and reverse rotation of the rotating disk (5), the rust removal belt (64) fully grinds and removes rust from the surface of the steel bar. Step 5: The straightened and rust-removed steel bar enters the inner cavity of the traction box (10) and comes into contact with the surface of the support wheel (84). At the same time, under the torsion force of the torsion spring (97), the swing frame (96) elastically pushes downward and drives the extrusion wheel (92) to press against the surface of the steel bar; Step 6: At this time, the second servo motor (83) is turned on and drives the traction rod (81) to rotate. During the rotation process, the traction rod (81) drives the traction wheel (82) and the two synchronous gears (95) to rotate. Under the transmission action of the two synchronous gears (95), the main rotating rod (94) rotates, and under the transmission action of the two driving belt pulleys (98), the auxiliary rotating rod (91) and the extrusion wheel (92) rotate at the same time, and the rotation direction is opposite to the rotation direction of the traction wheel (82), so that the extrusion wheel (92) and the traction wheel (82) play a role in transmitting the steel bar to the right.
