Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for iron tower profiles. Background Technology

[0002] In the modern communications and power transmission fields, the demand for iron towers, as an important infrastructure, continues to grow. In the manufacturing process of iron towers, profile bending is one of the key processes, which directly affects the quality and production efficiency of iron towers.

[0003] Traditional methods of bending steel tower profiles mostly involve manual operation of bending equipment. Workers need to manually move the profiles onto the bending equipment for fixing, and then manually remove them after bending. This method has many drawbacks:

[0004] On the one hand, manual handling and processing of profiles are slow, resulting in low overall processing efficiency and making it difficult to meet the growing demand for iron tower production;

[0005] On the other hand, workers need to frequently move heavy profiles, which is physically demanding and can easily lead to fatigue over long periods of time. This not only affects work efficiency but also poses higher safety risks, such as workplace injuries caused by operational errors. In addition, manual operation has poor stability and consistency, making it difficult to guarantee the accuracy of profile bending, which may result in inconsistent product quality, increasing scrap rates and production costs.

A rotating shaft is rotatably connected inside the housing, and a grooved wheel is fixedly connected to the rotating shaft. The grooved wheel is meshed with the single round pin. A bending clamp is fixedly connected to one end of the rotating shaft, and the bending clamp is located above the housing.

[0011] Preferably, the output end of the motor is fixedly connected to a lead screw, which is rotatably connected to a support frame. The support frame has a sliding groove, and a slider is slidably connected inside the sliding groove. The slider is threadedly connected to the lead screw. A connecting shaft is fixedly connected to one side of the slider, and a hydraulic pump is fixedly connected to the bottom of the connecting shaft. A pneumatic gripper is fixedly connected to the output end of the hydraulic pump.

[0012] Preferably, the bending clamp and the fixing clamp are arranged in a straight line.

[0013] Preferably, both the bending clamp and the fixing clamp have an arc-shaped recess above them.

[0014] Preferably, the gear meshes with the serrations on the serrated slide bar.

[0015] Preferably, the single circular pin is a combination of a disc and a circular shaft, and the grooved wheel is fan-shaped and has a through groove for accommodating the circular shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) In this iron tower profile bending device, the pneumatic gripper takes away the bent profile while the power unit drives the rocker arm to rotate half a turn. The rocker arm drives the sawtooth slide rod to slide back in the opposite direction. The gear meshed on the sawtooth slide rod rotates half a turn in the opposite direction, which drives the single round pin to move the groove wheel back to its original position. Then the slider is moved to the side where the motor is. The hydraulic pump lowers the pneumatic gripper, the pneumatic gripper picks up the profile, the hydraulic pump retracts the pneumatic gripper, the motor reverses, and the slider slides in the opposite direction to the motor. When it reaches the top of the fixed clamping plate, the hydraulic pump lowers the pneumatic gripper, the pneumatic gripper releases the profile, and the profile falls into the groove of the fixed clamping plate and the bending clamping plate. The profile is bent and picked up and put away again. In this way, the automatic picking and putting away of the profile and the automatic processing are realized, which improves the processing efficiency and reduces the labor intensity of the workers.

The pneumatic clamp 9 is released to lower the profile, completing the processing of the profile.

[0035] Working principle: In use, the motor 4 starts rotating forward, driving the lead screw 5 to rotate. The slider 6 on the lead screw 5 moves to the side where the motor 4 is located. The hydraulic pump 8 starts, lowering the pneumatic gripper 9, which then picks up the profile. The hydraulic pump 8 then retracts the pneumatic gripper 9. The motor 4 reverses, and the slider 6 slides in the opposite direction to the location of the motor 4. When it reaches above the fixed clamping plate 2, the hydraulic pump 8 lowers the pneumatic gripper 9, releasing the profile. The profile falls into the groove of the fixed clamping plate 2 and the bending clamping plate 19. The power unit 1 is then started. 0. The output end of the power unit 10 drives the rocker arm 11 to rotate. When the rocker arm 11 rotates, it drives the serrated slide rod 12 to slide horizontally along the support column 13.

The single round pin 16 on the gear 14 rotates half a turn with the gear 14. At this time, the single round pin 16 pushes the grooved wheel 17 to rotate a certain angle. The grooved wheel 17 drives the rotating shaft 18 to rotate. The bending clamp 19 on the rotating shaft 18 rotates a certain angle accordingly, bending the profile. After bending, the hydraulic pump 8 lowers the pneumatic gripper 9, which then grips the bent profile. The motor 4 starts, and the lead screw 5 drives the slider 6 to slide to the opposite side of the motor 4, releasing the pneumatic gripper 9 and lowering the profile. Simultaneously, the power unit 10 drives the rocker arm 11 to rotate half a turn. The rocker arm 11 drives the serrated slide rod 12 to slide back in the opposite direction. The gear 14 meshing with the serrated slide rod 12 rotates half a turn in the opposite direction, causing the single round pin 16 to move the grooved wheel 17 back to its original position. The slider 6 is moved to the side where the motor 4 is located. The hydraulic pump 8 lowers the pneumatic gripper 9, which picks up the profile. The hydraulic pump 8 then retracts the pneumatic gripper 9, and the motor 4 reverses direction. The slider 6 slides in the opposite direction to the location of the motor 4.
