Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a high-efficiency steel bending device. Background Technology
[0002] With the acceleration of industrial modernization, steel is increasingly widely used in various fields. For example, in the construction industry, large buildings require a large amount of steel as a supporting structure, and some parts require the use of bent steel. In the machinery manufacturing field, the manufacturing of mechanical parts often requires bending steel into shape. At the same time, the rise of new energy vehicles and green buildings has increased the demand for lightweight metal materials, and the market potential for thin plate steel is huge. All of these require steel processing enterprises to have efficient bending capabilities to meet market demands. Traditional steel bending methods have many shortcomings. Manual bending not only requires high strength but is also inefficient and dangerous. Some early mechanical bending devices also have various problems, such as complex structures and inconvenient operation of some devices, low bending accuracy of some devices, and difficulty in meeting the needs of high-precision processing. Some devices also require frequent changes of equipment or molds when bending steel of different thicknesses and sizes, which is inconvenient and reduces production efficiency.
[0003] Bending sheet metal parts can optimize their internal stress distribution, improve load-bearing capacity and service life. Simultaneously, the bending process creates surface roughness, increasing the heat conduction area and improving thermal conductivity. Furthermore, precise control of bending process parameters can reduce thermal expansion and contraction, minimizing dimensional errors and stress concentration caused by temperature changes. Specific bending designs can also alter the surface conductivity of sheet metal parts, reducing electromagnetic interference and improving electromagnetic shielding. Current technologies use hydraulic equipment and molds for bending, achieving the bending action through hydraulic transmission. Hydraulic systems can provide significant pressure, making them suitable for processing large, thick steel plates and high-precision workpieces. They offer advantages such as structural stability, high precision, and accurate pressure control. The pressure of the hydraulic system can be precisely adjusted according to the material's thickness, strength, and bending requirements to ensure the bending effect. However, this bending method cannot control the width of the bend, failing to meet customer needs when wider steel is required, thus affecting the equipment's practicality. Utility Model Content

[0039] Specifically, the limiting component 204 ensures that the equipment moves precisely within a specific range, avoiding damage caused by excessive displacement. The limiting plate 2042 plays a key guiding and limiting role in mechanical movement, ensuring that the movement trajectory of the rotating component 205 is accurate. The rotating ball 2051 is rotatably connected to the fixed plate 203, allowing the rotating ball 2051 to rotate freely in a limited space, thereby driving the movement of the entire rotating component 205.

[0040] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The transmission assembly 305 includes two auxiliary gears 3051.

[0041] Specifically, the auxiliary gear 3051 meshes with the main gear 3042, ensuring the stability and reliability of the transmission.

[0042] Working principle: After the steel is placed, the top block 2061 is rotated, which drives the threaded rod 2062 to rotate as well. Since the threaded rod 2062 is threadedly connected to the pressure plate 201, the threaded rod 2062 pushes the triangular plate 2064 to slide downward together. When the triangular plate 2064 slides downward, it pushes the protruding plates 202 on both sides out from the inside of the pressure plate 201, thereby controlling the width of the bending point. Then, the hydraulic cylinder 6 is activated, which drives the fixed plate 203 to move downward. During the downward movement of the fixed plate 203, it drives the connecting rod 5 and the pressure plate 201 to move together. The pressure plate 201 can directly bend the steel. When the fixed plate 203 slides downward, it drives the rotating rods 2052 on both sides to rotate. The rotating rods 2052 then pull the extrusion plates 2054 on both sides to slide inward, thereby providing inward pressure to the steel, improving the bending efficiency, and allowing for arbitrary control of the width of the bending point, which is convenient for workers to use.
[0043] Place the threaded steel bar 302 inside the groove 4, and then start the motor 3041. The motor 3041 will drive the main gear 3042 to rotate. During the rotation of the main gear 3042, the power can be transferred to the secondary gear 3051, which in turn causes the secondary gear 3051 to start rotating. The secondary gear 3051 then drives the bidirectional threaded column 3052 to rotate. Since the straightening plate 303 is threadedly connected to the bidirectional threaded column 3052, the straightening plate 303 will move towards the opposite side along the outer wall of the bidirectional threaded column 3052 and straighten the inclined threaded steel bar 302, so that the threaded steel bar 302 is inserted into the hollow groove 301, which facilitates the subsequent bending operation. This straightens the threaded steel bar 302, reduces the bending time, and improves the practicality of the equipment.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
