[0002] An angle steel bending device is a piece of equipment used to bend angle steel into specific angles and shapes. This device is typically equipped with key components such as a hydraulic press, a positioning mechanism, and limit posts. The hydraulic press provides power to drive the angle steel to bend; the positioning mechanism, through components such as a protractor and a long plate, ensures that the angle steel is bent to the required angle, improving accuracy; the limit posts are used to fix the angle steel and prevent positional deviation during bending. Angle steel bending devices are widely used in construction, automotive, and machinery industries.

However, existing bending machines have some shortcomings in the bending process: when bending angle steel, manual restraint is required, and the two ends of the angle steel tend to curl upwards during bending, posing a safety hazard to manual restraint. Therefore, this utility model proposes an angle steel bending device for steel structure construction to solve the above problems. Utility Model Content

A motor is fixedly installed on one side of the base by a fixing frame. The output end of the motor is fixedly connected to one end of one of the pulleys, and one end of the pulley is fixedly connected to one end of the lead screw.

[0009] A further improvement is that the moving mechanism includes a cylinder and a connecting seat. The cylinder is symmetrically arranged on the back side of the base.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an angle steel bending device for steel structure construction, including a base 1, a concave plate 2, and a convex plate 3. The concave plate 2 is fixedly connected to the front of the base 1, and the convex plate 3 is provided on the back side of the concave plate 2. A moving mechanism is provided on the back side of the base 1, and the moving mechanism is fixedly connected to one side of the convex plate 3. Limiting mechanisms are symmetrically provided on both sides of the base 1, and a first limiting groove 4 is symmetrically rotatably connected to both sides of the concave plate 2. When the angle steel is placed between the concave plate 2 and the convex plate 3, both ends of the angle steel are respectively engaged with a set of first limiting grooves 4 and limiting mechanisms. The limiting mechanisms and first limiting grooves 4 can restrict the position of the angle steel, causing it to bend along a predetermined trajectory, avoiding deviation during the bending process of the angle steel and affecting the safety of employees.

[0020] The limiting mechanism includes a sliding seat 5, a slider 6, a moving wheel 7, and a lead screw 8. Sliding seats 5 are symmetrically arranged on both sides of the base 1. A slider 6 is slidably connected inside the sliding seat 5. A moving wheel 7 is hinged to the top of the slider 6. A lead screw 8 is rotatably connected inside the sliding seat 5. One end of the lead screw 8 passes through the interior of the slider 6 and is threadedly connected to it. The lead screw 8 and slider 6 are threadedly engaged, and the sliding seat 5 restricts the movement trajectory of the slider 6. When the lead screw 8 rotates in both directions, it can drive the slider 6 to move linearly back and forth. The moving wheel 7 is connected to the slider 6 as a whole, thus allowing the moving wheel 7 to adjust its position according to the bending trajectory of the angle steel, thereby ensuring that the moving wheel 7 always fits and limits the angle steel. In this way, the angle steel can bend along a predetermined trajectory, preventing deviation during bending and ensuring employee safety.

[0021] The first limiting groove 4 and the moving wheel 7 are parallel to each other. The first limiting groove 4, the moving wheel 7 and one side of the angle steel are fitted together. The front of the base 1 is provided with a rotating mechanism, which includes a pulley 9, a belt 10, a fixing frame 11 and a motor 12. One end of the lead screw 8 passes through the front of the base 1 and is fixedly connected to the pulley 9. The two pulleys 9 are connected to each other by the belt 10. The motor 12 is fixedly installed on one side of the base 1 by the fixing frame 11. The output end of the motor 12 is fixedly connected to one end of one of the pulleys 9. One end of the pulley 9 is fixedly connected to one end of the lead screw 8. The motor 12 can drive the pulley 9 at its output end to rotate. Both pulleys 9 rub against the belt 10, so that the motor 12 can drive both pulleys 9 to rotate at the same time. One end of each of the two pulleys 9 is connected to the two lead screws 8 as a whole, so as to drive the lead screw 8 to rotate inside the sliding seat 5.

[0022] The moving mechanism includes a cylinder 13 and a connecting seat 14. The cylinder 13 is symmetrically arranged on the back side of the base 1. The output end of the cylinder 13 is fixedly connected to the connecting seat 14. The bottom of the connecting seat 14 is fixedly connected to the top of the convex plate 3. The convex plate 3 is connected to the output end of the cylinder 13 through the connecting seat 14. The output end of the cylinder 13 can drive the convex plate 3 to move linearly back and forth. First, it drives the convex plate 3 to move closer to the concave plate 2 to compress the angle steel into a bent state. Then, it drives the convex plate 3 away from the concave plate 2 to remove the bent angle steel.

[0023] A limiting plate 15 is fixedly connected to the top of the convex plate 3. A second limiting groove 16 is provided on the side of the convex plate 3 adjacent to the concave plate 2. A fastening bolt 17 is threadedly connected to the top of the limiting plate 15. A hexagonal hole 18 is provided at the top of the fastening bolt 17. A matching groove for the fastening bolt 17 is provided on the inner side of the concave plate 2. Before bending the angle steel, it is inserted into the second limiting groove 16 on the convex plate 3. An electric drill with a hexagonal drill bit is inserted into the hexagonal hole 18. The electric drill automatically tightens the fastening bolt 17 and moves it downward. The fastening bolt 17 clamps the angle steel and locks it on one side of the convex plate 3, strengthening the limiting of the angle steel. The groove is close to the convex plate 3 and can accommodate the fastening bolt 17 inside the concave plate 2, avoiding interference with the bending of the angle steel.

[0024] The outer side of the fixing frame 11 is provided with a protective shell, which covers the motor 12. Multiple anti-collision strips are provided on the outer side of the protective shell. The protective shell and anti-collision strips can isolate the motor 12 from external objects, prevent external objects from directly contacting the motor 12, and protect the motor 12.

[0025] In this angle steel bending device, the motor 12 drives the pulley 9 at its output end to rotate. Both pulleys 9 rub against the belt 10, allowing the motor 12 to simultaneously drive both pulleys 9 to rotate. One end of each pulley 9 is connected to a lead screw 8, which drives the lead screw 8 to rotate inside the sliding seat 5. The lead screw 8 is threadedly engaged with the slider 6, and the sliding seat 5 restricts the movement trajectory of the slider 6. When the lead screw 8 rotates in both directions, it drives the slider 6 to move linearly back and forth. The moving wheel 7 is connected to the slider 6, allowing the moving wheel 7 to adjust its position according to the bending trajectory of the angle steel, thus ensuring that the moving wheel 7 is always in contact with and limited by the angle steel. In this way, the angle steel can bend along a predetermined trajectory, preventing deviation during the bending process and ensuring the safety of employees.
