Description

Technical Field

[0001] The present invention relates to the technical field of building steel bar straightening, and particularly to a building steel bar processing device. Background Art

[0002] Building steel bar straightening refers to the process of straightening the steel bars used in construction projects. During the construction of steel bars, they will be bent into square and circular shapes, and some steel bar waste will also be generated. If you want to reuse them, you need to remelt or straighten them again. Straightening is the most time-saving, labor-saving and cost-saving method. However, because one end of the steel bar may be overly bent, if you want to insert the steel bar into the jack of the straightening machine in the prior art, you need to manually straighten the end of the steel bar and then insert it, or cut off the overly bent position and then insert it. The above two methods are very time-consuming, laborious and time-consuming. Moreover, the length of the cut steel bar will change and it cannot be used according to the specified length. Also, for circular or square steel bars, the two ends are adjacent. If you want to insert them into the straightening machine in the prior art, you need to move the two ends away before inserting, otherwise the insertion will be difficult and time-consuming.

It can be inserted into the straightening machine for straightening without trimming the end of the steel bar, ensuring the length of the steel bar and avoiding waste of the steel bar;

[0040] A controller is fixed to one side of the mounting frame 11. The controller is electrically connected to the motor I 31, the motor II 57, and the pressure sensor.

[0041] Working principle:

[0042] First, start the motor I 31 through the controller to drive the gear I 32 to reverse, meeting the rotation direction for the one-way gear II 46 to drive the rotating shaft IV 44. So the one-way gear II 46 drives the rotating shaft IV 44 and the two bevel gears II 45 to rotate. The rotation of the bevel gear II 45 drives the bevel gear I 42 and the reciprocating screw II 41 to rotate, causing the lifting plate 47 to drive the upper rotating shaft VII 51, the upper gear IV 52, and the upper I-shaped wheel I 53 to move upward, creating a distance between the upper I-shaped wheel I 53 and the lower I-shaped wheel I 53. Then place the bent steel bar between the upper and lower I-shaped wheels I 53. When placing, place one end of the steel bar close to the side of the I-shaped wheel I 53 where the pressure sensor is installed (attached Figure 5 In the figure is a square steel bar shown. For circular and irregular shapes, they can be placed in the same way as shown in this figure). After placing, continue to start the motor I 31 to reverse, causing the lifting plate 47 that has moved to the top thread end of the reciprocating screw II 41 to move downward, making the upper gear IV 52 and the lower gear IV 52 mesh, and the upper I-shaped wheel I 53 and the lower I-shaped wheel I 53 clamp the steel bar. The pressure sensor transmits the pressure value to the controller. When the pressure reaches the standard, turn off the motor I 31 and start the motor II 57 to drive the rotating shaft V 58 to reverse. The reverse rotation of the rotating shaft V 58 drives the bevel gear IV 54, the rotating shaft VII 51, and the I-shaped wheel I 53 to rotate in the opposite direction, causing the steel bar to move towards the attached Figure 5The rightward movement in it straightens one end of the steel bar. After one end of the steel bar moves between the two sets of I-shaped wheels 53 and the pressure sensor can no longer detect pressure, the controller controls the second motor 57 to drive the fifth shaft 58 to rotate forward, resetting the straightened steel bar. Then, the second motor 57 is turned off and the first motor 31 is started to drive the first gear 32 to rotate forward, meeting the rotation direction for the one-way first gear 26 to drive the first reciprocating screw 25 to rotate. As a result, the moving plate 28 drives the rack 29 to move towards the first motor 31. The movement of the rack 29 causes the third gear 22 and the third shaft 21 to rotate. The third shaft 21 drives the L-shaped mounting plate 23 and the structures on the L-shaped mounting plate 23 to rotate. The one-way second gear 46 disengages from the first gear 32, and after rotating 90 degrees following the rotation, the fifth bevel gear 510 meshes with the sixth bevel gear 512. After the steel bar rotates following this, the straightened end faces the direction of the second I-shaped wheel 12. After rotating 90 degrees, the moving plate 28 also moves to the wire tail. The first motor 31 is turned off, and the second motor 57 is started to drive the fifth shaft 58, the third bevel gear 59, and the fifth bevel gear 510 to rotate. The fifth bevel gear 510 drives the sixth bevel gear 512 and the sixth shaft 511 to rotate. The sixth shaft 511 drives the connected second I-shaped wheel 12 to rotate. The second I-shaped wheel 12 drives the upper second I-shaped wheel 12 to rotate through the second gear 13. The upper second I-shaped wheel 12 drives other second I-shaped wheels 12 to operate through the sprocket 15 and the chain 16. At the same time, the first I-shaped wheel 53 also rotates due to the rotation of the third bevel gear 59. At this time, the first I-shaped wheel 53 smoothly inserts the straightened end of the steel bar between the second I-shaped wheels 12 for straightening, and then the steel bar emerges from one side of the second I-shaped wheels 12 and falls off.

[0043] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
