Abstract
Description
Technical Field
[0001] This invention relates to the field of electric vehicle frame processing equipment technology, specifically a bending device for frame production. Background Technology
[0002] The frame is the core skeleton structure of an electric vehicle, usually made of metal tubing. Its main purpose is to provide support and load-bearing for the entire vehicle, firmly connecting components such as the motor, battery, wheels, and control system into a whole, ensuring the structural stability and driving safety of the vehicle, while also affecting riding comfort and handling. The frame is generally manufactured using a cold bending forming process, with lightweight aluminum alloy tubing being a commonly used material. The tubing is bent using a bending device to adapt to complex streamlined designs and meet the installation requirements of different components.
[0003] The existing bending devices have gradually revealed their shortcomings during use, mainly in the following aspects:
[0004] First, the processing cycle is long. Specifically, there are two main factors that contribute to the long processing cycle of the device: First, during the bending process, one end of the tube must be clamped and fixed by the clamping fixture and transported to adjust the processing position, while the other end relies on the bending die and clamping die to complete the bending. Since one end of the tube is always fixed to the device, in order to avoid structural interference, the device can only process one position of the tube at a time. However, the number of bending points required for the frame is large, which leads to a long processing cycle. Second, after each bend is completed, the clamping fixture needs to transport the tube so that the next bending position is accurately moved between the bending die and the clamping die before processing can continue. Since there are many bending points in the frame tube, this kind of transport needs to be repeated, which leads to the accumulation of waiting time during the processing and further extends the processing cycle.
[0005] Secondly, the cumulative processing error is large. Specifically, during the complete processing of the frame tubing, the tubing needs to be moved and positioned multiple times to ensure that each processing position is accurately located between the bending die and the clamping die. However, each movement of the tubing will generate a certain positioning error. As multiple movements are carried out, these errors will accumulate continuously, eventually leading to an increase in the cumulative processing error, which will directly affect the final dimensions of the frame.
[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention
[0007] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a bending device for vehicle frame production. This device adopts a mode of clamping and fixing the middle and processing both ends simultaneously when processing vehicle frame tubing, and can achieve continuous processing without movement waiting time. Compared with the single-position processing mode of traditional devices and the waiting time caused by adjusting the processing position, it greatly shortens the processing cycle and improves processing efficiency.
[0008] During the complete processing of the frame tubing, the frame tubing does not need to be moved at all, thus avoiding the problem of error accumulation caused by repeated movement and adjustment of the processing position. This greatly reduces processing errors and ensures the accuracy of the final frame dimensions.

[0014] As an optimized solution, a first rotating sleeve is rotatably fitted on the outer wall of the support cylinder, the vertical rotating plate is fixedly connected to the first rotating sleeve, a drive motor is fixedly installed at the bottom of the processing table, the output shaft of the drive motor passes upward through the processing table, and a first transmission gear is fixedly fitted on the outer wall of both the first rotating sleeve and the output shaft of the drive motor, and the two first transmission gears mesh with each other.
[0015] As an optimized solution, a first built-in motor is fixedly installed inside both the vertical positioning cylinder and the lifting cylinder. The output shaft of the first built-in motor extends to the outside, and the first bending mold and the first clamping mold are both fixedly fitted onto the output shaft of the first built-in motor.
[0016] As an optimized solution, a built-in telescopic cylinder is fixedly installed at the bottom of the support cylinder, and the telescopic end of the built-in telescopic cylinder is fixedly connected to the lifting cylinder.
[0017] As an optimized solution, a second rotating sleeve is rotatably fitted on the outer wall of the first horizontal fixed cylinder. The horizontal rotating plate is fixedly connected to the second rotating sleeve. A servo motor is fixedly installed at the end of the vertical rotating plate. The output shaft of the servo motor passes through the vertical rotating plate. A second transmission gear is fixedly fitted on the outer wall of both the second rotating sleeve and the output shaft of the servo motor. The two second transmission gears mesh with each other.
[0018] As an optimized solution, a second built-in motor is fixedly installed inside both the first horizontal fixed cylinder and the horizontal positioning cylinder. The output shaft of the second built-in motor extends to the outside, and the second bending mold and the second clamping mold are both fixedly fitted onto the output shaft of the second built-in motor.
[0019] As an optimized solution, a third rotating sleeve is rotatably fitted on the outer wall of the second horizontal fixed cylinder. The rotating plate is fixedly connected to the third rotating sleeve. A control motor is fixedly installed at the bottom of the horizontal rotating plate. A third transmission gear is fixedly fitted on the outer wall of both the third rotating sleeve and the output shaft of the control motor. The two third transmission gears mesh with each other.
[0020] As an optimized solution, a third built-in motor is fixedly installed inside the second horizontal fixed cylinder, the output shaft of the third built-in motor extends to the outside, an adjusting motor is fixedly installed at the end of the rotating plate, the output shaft of the adjusting motor passes through the rotating plate, and the third bending mold and the third clamping mold are respectively fixedly fitted onto the output shaft of the third built-in motor and the output shaft of the adjusting motor.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. After the two clamping plates clamp and fix the frame tubing (e.g. Figure 1As shown in Figure 2), during the processing of the frame tubing, the built-in telescopic cylinder drives the first bending die to rise to a preset height. Under the drive of the first built-in motor, the second built-in motor, the third built-in motor, and the adjusting motor, the first bending die, the first clamping die, the second bending die, the second clamping die, the third bending die, and the third clamping die all rotate until their sidewalls contact the frame tubing (as shown in Figure 2). Figure 3 As shown), the drive motor drives the first rotating sleeve and the vertical rotating plate to rotate. When the first clamping die rotates, it performs the first bending of the frame tube under the cooperation of the first bending die (as shown). Figure 8 As shown), the servo motor then drives the second rotating sleeve and the horizontal rotating plate to rotate. During rotation, the second clamping die, in conjunction with the second bending die, performs a second bend on the frame tubing (as shown). Figure 9 As shown), then the motor is controlled to drive the third rotating sleeve and the rotating plate to rotate. When the third clamping die rotates, it performs a third bend on the frame tube with the cooperation of the third bending die (as shown). Figure 10 As shown), the processing of the frame tubes is now complete. This device uses a central clamping and fixing mode to process both ends of the frame tubes simultaneously, and can achieve continuous processing without movement waiting time. Compared with the traditional single-position processing mode and the waiting time caused by adjusting the processing position, it greatly shortens the processing cycle and improves processing efficiency.
[0023] 2. During the complete processing of the frame tubing, the frame tubing does not need to be moved at all, thus avoiding the problem of error accumulation caused by repeated movement and adjustment of the processing position, greatly reducing processing errors and ensuring the accuracy of the final frame dimensions.
[0024] 3. When clamping and fixing the frame tubing, the two first bending dies are in the low position, and the opening slots on the first bending die and the first clamping die, the opening slots on the second bending die and the second clamping die, and the opening slots on the third bending die and the third clamping die all face each other. At this time, the frame tubing can be placed horizontally between the two clamping plates without interfering with the equipment (e.g., Figure 1 (As shown in / 2), the two clamping plates slide towards each other and clamp and fix the frame tube. After the frame tube is processed, the first bending die, the first clamping die, the second bending die, the second clamping die, the third bending die, and the third clamping die all rotate until the opening slot faces the frame tube. The first bending die descends to the low position, the vertical rotating plate resets, and the two clamping plates slide back to back to release the clamping of the frame tube. The processed frame tube can be directly taken out. By adjusting the height of the first bending die and the position of the opening slot on the outer wall of the first bending die, the first clamping die, the second bending die, the second clamping die, the third bending die, and the third clamping die, the loading and unloading of the frame tube can be facilitated, improving the ease of use of the equipment.

[0049] The working principle of this device is as follows:
[0050] After the two clamping plates 7 clamp and fix the frame tube 3 (e.g.) Figure 1 As shown in Figure 2), during the processing of the frame tube 3, the built-in telescopic cylinder 26 drives the first bending die 14 to rise to a preset height. Under the drive of the first built-in motor 24, the second built-in motor 31, the third built-in motor 34, and the adjusting motor 35, the first bending die 14, the first clamping die 12, the second bending die 23, the second clamping die 21, the third bending die 19, and the third clamping die 20 all rotate until their sidewalls contact the frame tube 3 (as shown in Figure 2). Figure 3 As shown), the drive motor 28 drives the first rotating sleeve 25 and the vertical rotating plate 8 to rotate. When the first clamping die 12 rotates, it performs the first bending of the frame tube 3 under the cooperation of the first bending die 14 (as shown). Figure 8 As shown), the servo motor 32 then drives the second rotating sleeve 30 and the horizontal rotating plate 15 to rotate. During rotation, the second clamping die 21, in cooperation with the second bending die 23, performs a second bending of the frame tube 3 (as shown). Figure 9 (As shown), then control motor 36 to drive the third rotating sleeve 33 and rotating plate 17 to rotate. When the third clamping die 20 rotates, it performs a third bend on the frame tube 3 in cooperation with the third bending die 19 (as shown). Figure 10 As shown), the processing of the frame tube 3 is now complete. When processing the frame tube 3, the device adopts a mode of clamping and fixing the middle and processing both ends simultaneously, and can achieve continuous processing without movement waiting time. Compared with the traditional single-position processing mode and the waiting caused by adjusting the processing position, it greatly shortens the processing cycle and improves the processing efficiency.
[0051] During the complete processing of the frame tube 3, the frame tube 3 does not need to be moved at all, thus avoiding the problem of error accumulation caused by repeated movement and adjustment of the processing position, greatly reducing processing errors and ensuring the accuracy of the final dimensions of the frame.
[0052] When clamping and fixing the frame tube 3, the two first bending dies 14 are in the low position, and the opening slots 13 on the first bending die 14 and the first clamping die 12, the opening slots 13 on the second bending die 23 and the second clamping die 21, and the opening slots 13 on the third bending die 19 and the third clamping die 20 are all facing each other. At this time, the frame tube 3 can be placed horizontally between the two clamping plates 7 without interfering with the equipment (e.g., Figure 1(As shown in / 2), the two clamping plates 7 slide towards each other and clamp and fix the frame tube 3. After the frame tube 3 is processed, the first bending die 14, the first clamping die 12, the second bending die 23, the second clamping die 21, the third bending die 19 and the third clamping die 20 all rotate until the opening slot 13 faces the frame tube 3. The first bending die 14 descends to the low position, the vertical rotating plate 8 is reset, and the two clamping plates 7 slide back to back to release the clamping of the frame tube 3. The processed frame tube 3 can be directly taken out. By adjusting the height of the first bending die 14 and adjusting the position of the opening slot 13 on the outer wall of the first bending die 14, the first clamping die 12, the second bending die 23, the second clamping die 21, the third bending die 19 and the third clamping die 20, it is convenient to load and unload the frame tube 3, which improves the ease of use of the equipment.
