Technical Field

[0001] The utility model relates to the technical field of cover plate angle irons, in particular to a cover plate angle iron processing device. Background Art

[0002] In drainage ditch projects, it is necessary to produce ditch covers. The edging of the cover is usually done by using a toothless saw to cut two oblique seams at a 45° angle on one side of the angle steel bend to form a right-angled notch. The notch is then manually bent into a right angle before being assembled and welded into shape. Furthermore, it is inconvenient to fix the angle iron when making a right-angled notch on it, and the opening is prone to deviation. The accuracy of each opening is unstable. Moreover, if the angle iron is bent without being fixed, it is easy to deform other parts of the angle iron, resulting in non-standard processing and inconvenient use. In addition, manual cutting is time-consuming and labor-intensive. Therefore, a device for processing angle irons for cover plates is needed to solve the above technical problems.

[0024] The specific structure of the chute 7 is as follows Figure 4 As shown; the angle iron cut corners are placed at the center of the output end of the servo 11 to facilitate better bending of the angle iron; the inclination angles 15 of the two adjacent positioning plates 8 are symmetrical to each other, and the specific structure is as shown Figure 3 As shown;

[0025] When in use, place the angle iron on the processing platform 3 on the left, then place the angle iron on the positioning device at the far left end, then turn on the electric push rod 16, the electric push rod 16 drives the connecting rod 9 to move, the connecting rod 9 drives the slider 6 connected to it to move, the slider 6 slides on the slide column 5 according to the structure of the slide groove 7, and then the slider 6 drives the positioning plate 8 to move, the positioning plate 8 moves to clamp the angle iron, thereby fixing one end of the angle iron, and then turn on the cutting machine 2 to cut one end of the angle iron into a 45-degree angle for easy bending. The structural changes of the positioning device are as follows: Figure 4 As shown, it is convenient to understand its structure;

[0026] Then control the leftmost positioning device to reset, then put the angle iron between the two leftmost positioning devices, and then control the electric push rod 16 to make the positioning plates 8 in the two positioning devices clamp the two ends of the angle iron. Figure 2 As shown, the angle iron is then opened at a right angle to facilitate rectangular bending;

[0027] After the angle iron is cut, it moves to the right. The angle iron reaches the bending arm 10. Place the angle iron with a right angle on one end of the bending arm 10. Then open the two positioning devices on the right end and clamp the two right-angle ends of the angle iron. Figure 3 As shown, the steering gear 11 is turned on, and the steering gear 11 drives the bending arm 10 to rotate 90 degrees, and then the angle iron is bent, which is convenient for bending after the angle iron is fixed, and is more convenient to use. In the traditional bending process, if the angle iron is bent without being fixed, other positions of the angle iron are easily deformed, instead of accurately bending the right angle of the angle iron directly, which is easy to affect the processing and use of the angle iron.

[0028] The setting of the circular slide rail 14 is convenient for assisting the processing of angle iron; and the setting of the threaded rod 12, by rotating the threaded rod 12 to drive the mounting block 4 slidably connected to the bending arm 10 to slide, the position of the mounting block 4 can be adjusted. When the mounting block 4 is farther away from the steering gear 11, it is more labor-saving when bending the mounting block 4. When the angle iron is harder or difficult to bend, the distance between the mounting block 4 and the bending arm 10 can be adjusted, which is convenient for adjustment.

[0029] The inclined angle 15 on the positioning plate 8 facilitates a wide range of fixed cutting angles without affecting cutting, making cutting more convenient and preventing unnecessary bending from occurring during bending.

The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
