Description

Technical Field

[0001] The invention belongs to the field of steel bar rust removal, and particularly relates to a steel bar rust removal device and a rust removal method for building construction. Background Art

[0002] Some bent steel bars with one or both ends bent are often used in construction. They are a kind of longitudinal force-bearing steel bars of the beam. They are bent from the main bars at the bottom of the beam to the top of the beam as negative bars or anchors along the longitudinal direction of the beam. Their main function is to improve the shear resistance of the beam. After the steel bars are bent, they are sometimes not put into use immediately. They are very easy to rust after being placed for a long time. However, the existing steel bar rust removal machines are used to remove rust from straight steel bars, or to remove rust while straightening the steel bars. The usual rust removal method for bent steel bars is manual rust removal, which has low rust removal efficiency, poor effect, and waste of manpower. For this reason, we propose a steel bar rust removal device and a rust removal method for construction to remove rust from bent steel bars. Summary of the invention

[0046] A rust removal method for a steel bar rust removal device for construction, comprising the following steps:

[0047] Step 1: According to the size of the bent steel bar, adjust the knob 510 so that the upper pressing wheel 56 and the lower pressing wheel 512 of the feed press the steel bar tightly. After the adjustment is completed, turn the first locking bolt 59 and the second locking bolt 515 to fix the position of the upper pressing wheel 56 and the lower pressing wheel 512 of the feed;

[0048] Step 2: Start the motor 75 to drive the upper feed pressing wheel 56 to rotate, and at the same time drive the first wire wheel 42 to rotate, so that the bent steel bar enters between the first side plate 2 and the second side plate 3 from the feed trough 23, and the first wire wheel 42 grinds and removes rust from the main body of the steel bar;

[0049] Step 3: When the first proximity sensor 22 detects that the bending part of the steel bar enters the middle of the rust removal box 63, the output end of the telescopic cylinder 720 is controlled to extend, and the first friction plate 713 and the second friction plate 714 are pressed, and the sixth transmission shaft 716 rotates synchronously with the fourth gear 711. The sliding plate 62 is pushed by the first rack 76 and moves forward at the same speed as the steel bar. The spring 64 is stretched, and at the same time, the sliding plate 62 slides on the first slide rail 61, so that the third gear 654 rotates, driving the groove cam 653 to rotate, and the connecting rod 636 reciprocates, driving the rust removal box 63 to reciprocate in the sliding plate 62. At the same time, the third gear 654 drives the second transmission shaft 635 to rotate through the meshing of the second bevel gear 657 and the first bevel gear 656, and drives the second wire wheel 632 to rotate. Therefore, the second wire wheel 632 can rotate and reciprocate in the axial direction of the steel bar, so that the steel bar is fully polished and rust-removed;

[0050] Step 4: When the second proximity sensor 35 detects that the rust removal box 63 has arrived, the output end of the telescopic cylinder 720 is retracted, the first friction plate 713 is separated from the second friction plate 714, and the spring 64 is retracted to pull the rust removal box 63 back to its original position;

[0051] Step 5: The front end of the steel bar passes through the discharge chute 34, leaves between the first side plate 2 and the second side plate 3, and then moves outwards under the guidance of the discharge pressing wheel 32;

[0052] Step 6: The bend at the rear end of the steel bar is detected by the first proximity sensor 22 and polished until the second proximity sensor 35 detects the arrival of the rust removal box 63 again, the spring 64 retracts and pulls the rust removal box 63 back to its original position, and then the steel bar completely leaves the device, completing the rust removal work.

8. The rust removal method for a steel bar rust removal device for construction according to claim 7, characterized in that: The rust removal method comprises the following steps: Step 1: According to the size of the bent steel bar, adjust the knob (510) so that the upper feed pressing wheel (56) and the lower feed pressing wheel (512) press the steel bar tightly. After the adjustment is completed, turn the first locking bolt (59) and the second locking bolt (515) to fix the position of the upper feed pressing wheel (56) and the lower feed pressing wheel (512); Step 2: Start the motor (75) to drive the upper feed pressing wheel (56) to rotate, and at the same time drive the first wire wheel (42) to rotate, so that the bent steel bar enters between the first side plate (2) and the second side plate (3) from the feed trough (23), and the first wire wheel (42) grinds and removes rust from the main body of the steel bar; Step 3: When the first proximity sensor (22) detects that the bent part of the steel bar enters the middle of the rust removal box (63), the output end of the telescopic cylinder (720) is controlled to extend, the first friction plate (713) and the second friction plate (714) are pressed tightly, the sixth transmission shaft (716) and the fourth gear (711) rotate synchronously, the sliding plate (62) is pushed by the first rack (76) and moves forward at the same speed as the steel bar, the spring (64) is stretched, and at the same time the sliding plate (62) slides on the first slide rail (61), so that the third gear (711) rotates synchronously. The wheel (654) rotates, driving the groove cam (653) to rotate, and the connecting rod (636) to reciprocate, driving the rust removal box (63) to reciprocate in the sliding plate (62). At the same time, the third gear (654) drives the second transmission shaft (635) to rotate through the meshing of the second bevel gear (657) and the first bevel gear (656), driving the second wire wheel (632) to rotate. Therefore, the second wire wheel (632) can rotate and reciprocate in the axial direction of the steel bar, so that the steel bar is fully polished and rust-removed. Step 4: When the second proximity sensor (35) detects that the rust removal box (63) has arrived, the output end of the telescopic cylinder (720) is retracted, the first friction plate (713) is separated from the second friction plate (714), and the spring (64) is retracted to pull the rust removal box (63) back to its original position; Step 5: The front end of the steel bar passes through the discharge chute (34), leaves between the first side plate (2) and the second side plate (3), and then moves outwards under the guidance of the discharge pressing wheel (32); Step 6: The bend at the rear end of the steel bar is detected by the first proximity sensor (22) and is polished until the second proximity sensor (35) detects the arrival of the rust removal box (63) again, and the spring (64) retracts to pull the rust removal box (63) back to its original position, and then the steel bar completely leaves the device, completing the rust removal work.
