DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a bending device for processing steel bars in construction engineering, comprising a bending machine housing 1 and a fixing mechanism 3, a support mechanism 2 is arranged on one side of the bending machine housing 1, and a fixing mechanism 3 is installed on one side of the surface of the bending machine housing 1;

[0019] The fixing mechanism 3 includes a mounting groove 301, a limiting rod 302, a bidirectional screw rod 303, an internally threaded tube 304, a motor 305, a movable slide plate 306, a guide sleeve 307, a spring 308 and a clamping plate 309. One side of the bending machine housing 1 is fixedly connected with the mounting groove 301, one end of the mounting groove 301 is fixedly installed with the limiting rod 302, one end of the mounting groove 301 is provided with a bidirectional screw rod 303, the outer ring of the bidirectional screw rod 303 is threadedly connected with the internally threaded tube 304, one end of the bidirectional screw rod 303 is connected with the motor 305, one side of the surface of the internally threaded tube 304 is fixedly connected with the movable slide plate 306, both ends of the movable slide plate 306 are fixedly connected with the guide sleeve 307, one side of the surface of the movable slide plate 306 is fixedly connected with the spring 308, one end of the spring 308 is welded with the clamping plate 309, through the mounting groove 301, the limiting rod 302, the bidirectional screw rod 303, the internally threaded tube 304, the guide sleeve 307 is fixedly connected with the guide sleeve 307, the spring 308 is fixedly connected with the spring 308, and the clamping plate 309 is welded with the clamping plate 309. 4. The arrangement of the motor 305, the movable slide plate 306, the guide sleeve 307, the spring 308 and the clamping plate 309. When the steel bar needs to be fixed during processing, the motor 305 is connected to make the motor 305 work. When the motor 305 rotates, it will drive the bidirectional screw rod 303, so that the internal threaded tube 304 threadedly connected to the bidirectional screw rod 303 moves. When the internal threaded tube 304 moves, it will also drive the movable slide plate 306 to move. When the movable slide plate 306 moves, the spring 308 and the clamping plate 309 on one side of its surface also move accordingly, and the steel bar is placed between the two clamping plates 309. As the movable slide plate 306 moves, the two clamping plates 309 gradually approach the steel bar. After the clamping plates 309 contact the steel bar, the spring 308 is compressed. The elastic force of the spring 308 enables the clamping plates 309 to tightly clamp the steel bar, thereby fixing the steel bar.

[0020] Furthermore, the limiting rod 302 and the movable slide 306 form a sliding structure, and the movable slide 306 forms a sliding structure with the bidirectional screw rod 303 through the internal threaded tube 304. Through the setting of the internal threaded tube 304, the movable slide 306 can be easily moved at one end of the bidirectional screw rod 303.

[0021] Furthermore, two groups of limit rods 302 are provided, three groups of springs 308 are provided, and the clamping plate 309 is a semicircular structure. Through the setting of the clamping plate 309, the semicircular clamping plate 309 can better fit the shape of the steel bar, increase the contact area with the steel bar, and thus improve the clamping effect and stability.

[0022] Furthermore, the support mechanism 2 includes an integrated screw 201, a base 202, a first nut 203, a second nut 204 and an anti-slip base glue 205. One end of the bending machine housing 1 is connected to the integrated screw 201, one end of the integrated screw 201 is connected to the base 202, one end of the integrated screw 201 is connected to the first nut 203, one end of the integrated screw 201 is connected to the second nut 204, and one side of the surface of the base 202 is bonded with an anti-slip base glue 205. By setting 204 and anti-skid base glue 205, when it is necessary to strengthen the support of the bending machine housing 1, firstly, the integrated screw 201 is passed through the base 202, and then the base 202 is fixed by the combination of the first nut 203 and the integrated screw 201. The anti-skid base glue 205 bonded on one side of the surface of the base 202 can increase the friction with the contact surface to prevent the base 202 from sliding during the bending work. Finally, the integrated screw 201 is fixed on the bending machine housing 1, and the second nut 204 is used to firmly fix it to ensure the stability and safety of the bending machine housing 1.

[0023] Furthermore, the integrated screw 201 is threadedly connected to the first nut 203, and the anti-skid base glue 205 is made of PVC. Through the setting of the anti-skid base glue 205, when the base 202 contacts the ground, the anti-skid base glue 205 made of PVC material can increase the friction, effectively preventing the base 202 from sliding due to equipment vibration or external force during operation, thereby ensuring the stability and safety of the bending machine housing 1.

[0024] Working principle: First, when it is necessary to strengthen the support of the bending machine housing 1, the integrated screw 201 is passed through the base 202, and then the base 202 is fixed by the combination of the first nut 203 and the integrated screw 201. The anti-slip base glue 205 bonded on one side of the surface of the base 202 can increase the friction with the contact surface to prevent the base 202 from sliding during the bending work. Finally, the integrated screw 201 is fixed to the bending machine housing 1, and the second nut 204 is used to firmly fix it to ensure the stability and safety of the bending machine housing 1. Secondly, when the steel bars need to be fixed during processing, the motor 305 is started, and the rotation of the motor 305 drives the bidirectional screw 303 to rotate. Since the bidirectional screw 303 is threadedly connected to the internal threaded tube 304, the rotation of the bidirectional screw 303 will cause the internal threaded tube 304 to move along its direction. Then, when the internal threaded tube 304 moves, it will also drive the moving slide 306 to move in position. The guide sleeves 307 at both ends of the moving slide 306 slide along the limit rod 302. The limit rod 302 limits and guides the moving direction of the moving slide 306 to ensure that the moving slide 306 moves smoothly without deviation or rotation. When the moving slide 306 moves, the spring 308 and the clamping plate 309 on one side of its surface also move accordingly, placing the steel bar between the two clamping plates 309. As the moving slide 306 moves, the two clamping plates 309 gradually approach the steel bar. After the clamping plates 309 contact the steel bar, the spring 308 is compressed. The elastic force of the spring 308 enables the clamping plates 309 to tightly clamp the steel bar, thereby fixing the steel bar and providing stable conditions for subsequent bending processing.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
