Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a bending device for a tricycle frame rod. Background Art

[0002] A bending machine is an indispensable machine in the field of metal processing. It can process metal sheets into required shapes and sizes according to specific process requirements. This machine is usually made of a strong all-steel structure, ensuring its stability and durability during operation.

[0003] The tricycle frame rod is of a tubular structure and needs to be bent into a specified shape to meet the needs of the product.

[0004] In the prior art, the automatic bending device for the frame tube body includes: a workbench, a clamping tooling, a bending support wheel, a bending pushing wheel, a bending seat, and a rotary linear pushing device. The clamping tooling is installed on the workbench and is used to clamp the first end of the tricycle frame rod. A rotatable bending support wheel is installed on the workbench, and a bending pushing wheel is arranged beside the bending support wheel. The bending pushing wheel is rotatably installed on the bending seat, and the bending seat is connected to the output end of the rotary linear pushing device. The second end of the tricycle frame rod is clamped between the bending pushing wheel and the bending support wheel. When the rotary linear pushing device drives the bending seat to rotate around the bending support wheel, the bending pushing wheel pushes the tricycle frame rod to bend.

[0005] Although the automatic bending device for the frame tube body can bend the tricycle frame rod, there are still some drawbacks for the tricycle frame rod. The bending support wheel cannot support the second end of the tricycle frame rod, resulting in the second end of the tricycle frame rod moving down randomly, so that the bending position is not the required bending position, and the product does not meet the regulations. Summary of the Utility Model

[0011] The guide wheel is rotatably mounted on the bending mechanism, the bending mechanism is mounted beside the first guide plate and the second guide plate, the bending mechanism can rotate around the axis of the first guide plate, a connecting mechanism is further arranged between the rotating mechanism and the bending mechanism, and the connecting mechanism is staggered with the clamping mechanism;

[0012] The lifting and positioning mechanism is arranged beside the connection between the output end of the rotating mechanism and the second guide plate. The lifting and positioning mechanism is used to position the first guide plate groove or the second guide plate groove to align with the guide wheel groove. One of the inner wall of the first guide plate groove and the inner wall of the second guide plate groove cooperates with the inner wall of the guide wheel groove to clamp the tricycle frame rod.

[0013] Preferably, the lifting and positioning mechanism includes: a threaded disk, a screw ring and a nut. The threaded disk is sleeved and fixed on the output end of the rotating mechanism. The threaded disk is supported by the second workbench. The screw ring is threadedly connected to the threaded disk. The output end of the rotating mechanism is threadedly connected with a nut. The nut is located above the first guide disk, and the screw ring supports the second guide disk.

[0014] Preferably, the bending mechanism is a block structure and is located on one side of the second workbench. Two protrusions are provided on the side of the bending mechanism close to the second workbench. A connecting rod is provided between the two protrusions. The guide wheel is sleeved on the connecting rod, and at least two guide wheels are provided.

[0015] Preferably, the connecting mechanism includes: a driving disk and a first driving arm, the driving disk is fixed on the output end of the rotating mechanism, the driving disk is located below the threaded disk, the second workbench supports the threaded disk through the driving disk, and the driving disk and the bending mechanism are connected through the first driving arm.

[0016] Preferably, a second driving arm is connected to the top of the bending mechanism, and the other end of the second driving arm is connected to one side of the top of the output end of the rotating mechanism.

[0017] Preferably, the rotating mechanism is a rotary drive motor, the output shaft of the rotary motor can rotate along the Y-axis direction, and the output shaft of the rotary motor is the output end of the rotary drive motor.

[0018] Preferably, a conveying guide rail is installed on the first workbench, and two sliding grooves are formed in the conveying guide rail, and the sliding seat can slide in the sliding grooves.

[0019] Compared with the prior art, the utility model has the following beneficial effects: The three-wheel vehicle frame rod bending device is provided with a linear pushing device and a bending device. The pipe body is pushed to the bending device by the linear pushing device for bending treatment, so that multiple bends can be made on the three-wheel vehicle frame rod. The three-wheel vehicle frame of this utility model needs to be bent twice. After the initial positioning, the first bend is made, and then the linear pushing device pushes the three-wheel vehicle frame rod to move, so that the bending position changes, and then the second bend is made to meet the requirements of the two bends and ensure that the product can meet the quality requirements. Then, a first guide disk, a second guide disk and the grooves on the guide wheels are provided. The grooves are for the three-wheel vehicle frame rod to be placed in, and at the same time, the grooves support the end of the three-wheel vehicle frame rod away from the sliding seat. In this way, both ends of the three-wheel vehicle frame rod can be supported during the bending process, avoiding random bending at the bending position due to lack of support at the bending position and ensuring the bending quality. When bending, first adjust the first guide disk or the second guide disk to a position aligned with the guide wheels. The outer diameter of the bending position of the first guide disk is different from the outer diameter of the bending position of the second guide disk. Since the bending position of the three-wheel vehicle frame rod is bent around the outer diameter of the bending position of the first guide disk or the outer diameter of the bending position of the second guide disk, the outer diameter of the bending position of the first guide disk or the outer diameter of the bending position of the second guide disk directly locates the bending degree of the bending position of the three-wheel vehicle frame rod. The lifting and positioning mechanism is to position the first guide disk or the second guide disk to be aligned with the guide wheels to ensure that the first guide disk or the second guide disk will not move randomly during bending. When bending, first keep the three-wheel vehicle frame rod between the guide wheels and the first guide disk or the second guide disk. Then, the output end of the rotating mechanism drives the bending mechanism to rotate through the connecting mechanism. The bending mechanism and the guide wheels rotate around the output end of the rotating mechanism, and at the same time, squeeze the three-wheel vehicle frame rod to bend and deform, thus realizing the bending.
