The rotating component can move the position of the second positioning block before rotating the working disk, and the second positioning block moves downward toward the first positioning block. The utility model can conveniently position and fix the steel bar, and can be easily reset after bending is completed, canceling the positioning of the steel bar, thereby facilitating material removal.

[0004] While the aforementioned technology allows for rapid retrieval of bent rebar, multiple sets of slots are provided on the rotating plate of the rebar bending machine.

During the rebar bending operation, impurities, rust, and other substances inevitably fall into the slots. These impurities can increase friction between the accessory and the slot, resulting in a loose or difficult insertion of the accessory, which can affect the accuracy and stability of the rebar bending. Therefore, a construction site rebar bending device is proposed to address this issue. Utility Model Content

The top of the positioning plate 5 is rotatably connected to a rotating plate 2, and the inner wall of the rotating plate 2 is provided with a fixed blocking mechanism 3; the fixed blocking mechanism 3 is provided to prevent dust and rust from falling into the interior of the rotating plate 2 when the steel bar is bent, and the fixed blocking mechanism 3 includes a support spring 306, one end of the support spring 306 The movable plate 304 is fixedly connected to the inner wall of the rotating plate 2, and the other end of the support spring 306 is fixedly connected to the movable plate 304. The elasticity of the support spring 306 enables the movable plate 304 to have a reset blocking function. The inner wall of the rotating plate 2 is plugged with an accessory 301, and the accessory 301 can be installed and removed from the inside of the rotating plate 2. The inner wall of the accessory 301 is elastically connected to the plug-in plate 303 through the connecting spring 302. The plug-in plate 303 is provided in two groups and is L-shaped. The outer wall of the positioning plate 5 is provided with a supporting mechanism 4, which is used to support longer steel bars.

[0033] Reference Figure 2 One end of the connecting spring 302 is fixedly connected to the outer wall of the plug board 303, and the other end of the connecting spring 302 is fixedly connected to the inner wall of the accessory 301. The outer wall of the plug board 303 is slidably connected to the inner wall of the accessory 301. The elasticity of the connecting spring 302 enables the plug board 303 to have reset and limit functions. The inner wall of the rotating plate 2 is provided with a plug hole 305, and the outer wall of the plug board 303 is plugged into the inner wall of the plug hole 305. The two groups of plug boards 303 are staggered, and the staggered setting can achieve the purpose of saving space.

[0034] Reference Figure 2 The bottom end of the accessory 301 contacts the outer wall of the movable plate 304. The contact between the two enables the movable plate 304 to move downward to achieve the installation purpose. The outer wall of the movable plate 304 is slidably connected to the inner wall of the rotating plate 2. The interior of the rotating plate 2 is provided with a slot hole that is compatible with the accessory 301. This is the existing technology, and the size of the movable plate 304 is compatible with the slot hole. The bottom end of the plug-in board 303 is provided with a slope. The slope is set to facilitate installation, so that the accessory 301 can be directly inserted when installing it.

[0035] Reference Figure 3-Figure 4The support mechanism 4 includes a support block 404, the outer wall of the support block 404 is fixedly connected to the outer wall of the positioning plate 5, the inner wall of the support block 404 is elastically connected to the limiting column 405 through the limiting spring 406, the outer wall of the limiting column 405 passes through the support block 404, and the penetration setting is convenient for relevant personnel to move and control the limiting column 405. The inner wall of the positioning plate 5 is slidably connected with a movable plate 401, and the movable plate 401 is set to a T shape. The T-shape setting prevents the movable plate 401 from slipping. The top of the movable plate 401 is fixedly connected to a support seat 403, and the support seat 403 plays the role of supporting longer steel bars.

[0036] Reference Figure 3-Figure 4 One end of the limit spring 406 is fixedly connected to the outer wall of the limit column 405, and the other end of the limit spring 406 is fixedly connected to the inner wall of the support block 404. The outer wall of the limit column 405 is slidably connected to the inner wall of the support block 404. The elasticity of the limit spring 406 makes the limit column 405 have the reset and limiting functions. The top of the support seat 403 is provided with a limit hole 402, and the limit hole 402 is provided with multiple groups. The bottom end of the limit column 405 is inserted into the inner wall of the limit hole 402, and the two are inserted to fix the movable plate 401.

[0037] Working principle: When the staff needs to bend the steel bars, they first insert the accessory 301 into the slot on the turn plate 2 as needed. When the accessory 301 is inserted into the slot, the bottom inclined surfaces of the two sets of plug-in plates 303 will contact, and the two sets of plug-in plates 303 will move toward the middle due to the squeezing of the slot. At the same time, when the accessory 301 moves downward, the bottom end of the accessory 301 will contact and squeeze the top of the movable plate 304, causing the movable plate 304 to move downward until the plug-in plate 303 is plugged into the plug hole 305 and fixed. The other movable plates 304 that are not squeezed by the accessory 301 bounce up due to the elasticity of the support spring 306. The upward bounce of the movable plate 304 prevents dust on the steel bars from falling into the internal slot of the turn plate 2 during bending, thereby affecting the bending operation.

[0038] When there is no need to bend the steel bars, the two sets of plug-in plates 303 are moved inward so that the two sets of plug-in plates 303 are not plugged into the plug-in holes 305, and then the accessory 301 can be pulled out upward. When the accessory 301 is pulled out, the corresponding movable plate 304 is not squeezed and will bounce up due to the elasticity of the support spring 306, thereby preventing dust and impurities from falling into the interior of the rotating plate 2.

[0039] When it is necessary to bend some longer steel bars, the limit column 405 can be moved upward, thereby releasing the limit between the limit column 405 and the limit hole 402, and then the movable plate 401 can be pulled out to change the position of the support seat 403, so that the fulcrum supporting the steel bar will change. When the adjustment is completed, the limit column 405 is released so that the limit column 405 and the limit hole 402 are plugged into the limit to complete the fixation. The precise position change of the support seat 403 can ensure that the steel bar is accurately supported during the bending process, thereby improving the bending accuracy.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
