[0002] With the rapid development of modern industry, many fields such as construction engineering, machinery manufacturing, and automobile industry have increasingly higher requirements for the precision and efficiency of metal material processing. In the metal processing technology system, bending is a key process for shaping metal components, and its technical level directly affects product quality and production efficiency. As the core equipment for realizing the bending of metal materials, bending machines have developed into various types and technical routes over the years.

[0003] However, most existing bending machines are equipped with fixed-angle molds and preset bending structures, which can only complete conventional angle bending and cannot meet the special angle requirements in complex designs. At the same time, their limit clamps have a simple structure and fixed size specifications, which cannot be flexibly adjusted according to parameters such as the diameter and cross-sectional shape of the steel bars. When performing batch bending tasks of different types of steel bars, it is necessary to frequently change equipment or modify molds, which affects construction efficiency and processing accuracy.

[0004] Therefore, those skilled in the art provide a steel bar bending structure for building engineering to solve the problems mentioned in the background art. Utility Model Content

A bending disc is movably connected to the top of the toothed disc. The top of the bending disc is rotatably connected to the transmission box. A mold is threadedly connected to one side of the top of the bending disc.

[0007] Optionally, a movable door is provided on one side of the motor, and the movable door is movably connected to the housing via a hinge.

[0008] Optionally, a slide rail is fixedly connected to one side of the housing, and the toothed plate is slidably connected to the slide rail on one side.

[0009] Optionally, a stop block is provided at the bottom of the gear plate, the surface of the stop block is slidably connected to the housing, an eccentric wheel is provided at the bottom of the stop block, a fixed rod is movably connected to the inner side of the eccentric wheel, and both sides of the fixed rod are fixedly connected to the transmission box.

[0010] Optionally, a control rod is fixedly connected to one side of the eccentric wheel, and one side of the control rod passes through the inner cavity of the transmission box and extends to one side of the box body.

[0011] Optionally, a limiting clamp is provided on one side of the abutment block. The bottom of the limiting clamp is slidably connected to the transmission box.

[0013] Optionally, a limiting block is fixedly connected to one side of the top of the gear disc, and a limiting groove is formed at the bottom of the bending disc, with the limiting block and the limiting groove being slidably connected.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. The bending mechanism of this utility model can quickly adapt to the complex angle design of steel bars in architectural drawings. It can complete unconventional angle bending without changing the mold, easily meeting the steel bar processing requirements of irregular building nodes. The setting of bolts and sliders allows the operator to adjust the center distance between the connecting rod and the turntable by simply rotating the bolts to complete the adjustment of different bending angles. The operation is simple and requires no tools, which improves the convenience of the bending mechanism. Moreover, this design of quick adjustment of bending angle can avoid the time loss caused by changing the mold, significantly shorten the steel bar bending cycle, and improve the batch processing efficiency of steel bars in construction projects.

[0016] 2. The eccentric wheel and abutment block of this utility model allow the operator to drive the abutment block upward by pushing the control lever. The abutment block pushes the toothed disc, causing the toothed disc to disengage from the toothed plate, thus adjusting the bending angle. This makes operation convenient and improves the ease of adjusting the bending angle. The lead screw is a two-way threaded rod, allowing the two limit clamps on both sides to move inward simultaneously, ensuring that the rebar is always in the center of the limit clamp, thereby improving bending accuracy. Furthermore, the limit clamps can be adjusted according to the diameter of the rebar, solving the problem of frequent limit clamp replacements required by traditional devices when bending different types of rebar, thus improving the practicality of the device.

The top of the bending disc 309 is rotatably connected to the transmission box 2. A mold 310 is threadedly connected to one side of the top of the bending disc 309.

[0027] In this embodiment: the top side of the box 1 is a flat surface that can be used as a placement platform to place the steel bars that need to be bent. The top of the transmission box 2 is provided with a movable groove. One side of the bending disc 309 is rotatably connected to the movable groove, which can limit the range of motion of the bending disc 309. The groove 303 can limit the range of motion and movement of the slider 304. One side of the bolt 305 passes through the turntable 302 and is fixedly connected to a knob. The knob is located inside the movable door 4 so that the operator can adjust the bending angle by turning the knob.

[0028] Example 2:

[0030] In this embodiment: there are two movable doors 4, so that the staff can open the movable doors 4 to repair or replace components such as motor 301. The slide rail 5 is located on one side of the gear plate 308, which can restrict the movement of the gear plate 307. There are two abutment blocks 6.

[0031] The implementation principle of this utility model is as follows: In use, by rotating the handle 12, the handle 12 drives the lead screw 11 to rotate, and the lead screw 11 drives the limiting clamp 10 to move. After adjusting the limiting clamp 10 to a position suitable for the steel bar, the steel bar is placed between the two limiting clamps 10. The motor 301 is started, and the motor 301 drives the turntable 302 to rotate. The turntable 302 drives the connecting rod 306 to move, the connecting rod 306 drives the toothed plate 307 to move, the toothed plate 307 drives the toothed disc 308 to rotate, the toothed disc 308 drives the bending disc 309 to rotate, and the bending disc 309 drives the mold 310 to rotate. The steel bars are bent. When the bending angle needs to be adjusted, the control lever 9 is pushed upward. The control lever 9 drives the eccentric wheel 7 to rotate and push the abutment block 6. The abutment block 6 pushes the toothed disc 308. The toothed disc 308 moves upward and disengages from the toothed plate 307. Then, the knob is turned. The knob drives the bolt 305 to rotate. The bolt 305 drives the slider 304 to move along the slide groove. The slider 304 drives the connecting rod 306 to move. The connecting rod 306 drives the toothed plate 307 to move.
