[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4This utility model provides an embodiment of a steel bar bending machine for construction engineering, including a bending machine body 1. Slide grooves 2 are provided on both sides of the bending machine body 1. A slider 3 is slidably installed inside the slide grooves 2. An mounting sleeve 4 is fixedly installed on the outside of the slider 3. A sliding plate 5 is slidably installed inside the mounting sleeve 4. A connecting plate 6 is provided on the top of the bending machine body 1. The sides of the connecting plate 6 and the inside of the sliding plate 5 are fixedly installed. A limiting component 7 for limiting the sliding plate 5 is provided inside one set of sliding plates 5. An adsorption component 8 for adsorbing iron filings is provided on the top of the bending machine body 1. First, the steel bar to be bent can be placed on the bending machine body 1 for bending. After the steel bar is bent, the mounting sleeve 4 can be pulled. The movement of the mounting sleeve 4 causes the connecting plate 6, sliding plate 5, and slider 3 to move. When the connecting plate 6 moves to the top of the bending fixture, the height of the sliding plate 5 and the connecting plate 6 can be adjusted by the limiting component 7. After the connecting plate 6 moves to a suitable distance, the adsorption component 8 can then repeatedly adsorb the iron filings on the bending machine body 1.

[0031] Reference Figures 1-4 The limiting component 7 includes two sets of placement slots 71. Each placement slot 71 is located inside one set of sliding plates 5. A limiting plate 72 is slidably installed inside the placement slot 71. Limiting slots 73 are provided on both the front and rear sides of one set of mounting sleeves 4. The limiting plate 72 and the limiting slots 73 are interlocked. A spring 74 is fixedly installed on one side of the inner wall of the placement slot 71. The outer end of the spring 74 is fixedly installed on the inner side of the limiting plate 72. Through the cooperation of the placement slot 71, the limiting plate 72, the limiting slots 73, and the spring 74, the limiting plate 72 can be pressed inwards. At this time, the limiting plate 72 will enter the placement slot 71. The inward movement of the limiting plate 72 will compress the spring 74, and then push the sliding plate 5 upwards. The sliding plate 5 drives the connecting plate 6 to move upwards, thus preventing the connecting plate 6 from affecting... In the steel bar bending operation, a set of mounting sleeves 4 has stabilizing grooves 75 on both the front and rear sides. A stabilizing block 76 is fixedly installed on the outer side of the limiting plate 72. The stabilizing block 76 and the stabilizing groove 75 are slidably installed. Through the cooperation of the stabilizing groove 75 and the stabilizing block 76, when the stabilizing block 76 is pushed inward, it can drive the limiting plate 72 and the limiting groove 73 to disengage. This can prevent the limiting plate 72 from being unable to effectively disengage from the limiting groove 73 simply by pressing it, thus preventing the height of the connecting plate 6 from being adjusted. A handle 11 is fixedly installed on the left side of a set of sliding plates 5. The handle 11 and the sliding plate 5 are used together. By setting the handle 11, the limiting of the sliding plate 5 and the mounting sleeve 4 can be released. At this time, the handle 11 can be pulled upward to conveniently adjust the height of the sliding plate 5 and the connecting plate 6.

[0032] Reference Figures 1-4The adsorption assembly 8 includes several sets of powerful magnets 81. A fixing rod 82 is fixedly mounted on the top of each powerful magnet 81. The top of the fixing rod 82 extends through to the top of the connecting plate 6 and slides with the connecting plate 6. Through the cooperation of the powerful magnets 81 and the fixing rod 82, the connecting plate 6 can be adjusted to the top of the bending fixture. At this point, the mounting sleeve 4 can be pushed, and the mounting sleeve 4 can attract iron filings through the powerful magnets 81. A fixing block 83 is provided on the top of the fixing rod 82, and the bottom of the fixing block 83 contacts the top of the connecting plate 6. A bolt 84 is provided on the top of the connecting plate 6, and the bottom of the bolt 84 passes through the fixing block 83 and the fixing rod 82. The bolt 84 is connected to the fixing block 83 and the fixing rod. The 82 threaded installation, through the cooperation of the fixing block 83 and the bolt 84, allows the bolt 84 to be rotated when the top of the fixing rod 82 passes through the connecting plate 6. At this time, the bolt 84 will enter the interior of the fixing rod 82, and the bottom of the fixing block 83 will also contact the top of the connecting plate 6. At this time, the fixing rod 82 and the strong magnet 81 can be limited. Rectangular blocks 9 are fixedly installed at the four corners of the bottom of the bending machine body 1. Rollers 10 are rotatably installed on the outside of the rectangular blocks 9 through the shaft pins. Through the cooperation of the rectangular blocks 9 and the rollers 10, when the bending machine body 1 is pushed, the bending machine body 1 will move under the action of the rollers 10, thereby improving the convenience of moving the bending machine body 1.

[0033] Working principle: First, the steel bar to be bent can be placed on the bending machine body 1 for bending. After the steel bar is bent, the mounting sleeve 4 can be pulled. The movement of the mounting sleeve 4 drives the connecting plate 6, the sliding plate 5, and the slider 3 to move. When the connecting plate 6 moves to the top of the bending fixture, the stabilizing block 76 can be pressed inward. The stabilizing block 76 moves inward, driving the limiting plate 72 to move inward. The limiting plate 72 moves inward, compressing the spring 74. After the limiting plate 72 and the limiting groove 73 disengage, the handle 11 can be pressed down to the bottom. The handle 11 will drive the slider... Plate 5 and connecting plate 6 move to the bottom. When connecting plate 6 moves to the appropriate position, the stabilizing block 76 can be released. Since connecting plate 6 is always under the elastic force of spring 74, the limiting plate 72 will enter the limiting groove 73. Then, the mounting sleeve 4 can be pushed back and forth. The movement of mounting sleeve 4 will drive the connecting plate 6 and the strong magnet 81 to move, thereby attracting iron filings on the bending machine body 1. When the strong magnet 81 needs to be replaced, the bolt 84 of the limiting fixing block 83 can be removed, thereby replacing the strong magnet 81.

[0034] 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.
