Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal bending processing, in particular to a boat frame bending device for a boat. BACKGROUND

[0002] Under the background of rapid promotion of agricultural mechanization, as the core equipment for paddy field operation in the south, the market demand for the boat is increasing by more than 15% per year. The boat frame, as the bearing matrix of the boat, needs to have high strength and complex curved surface structure to adapt to the impact of muddy terrain and water tightness requirements. The processing of the boat frame

[0003] Generally uses a bending device, and the existing bending device has the following problems in actual use:

[0004] 1. Fragmentation of traditional processing flow, low production efficiency:

[0005] The existing boat frame bending adopts single-station equipment for step-by-step processing, which needs manual clamping and transporting the plate multiple times, and the single processing period is more than 30 minutes, and the waiting time between processes accounts for more than 40%, which is difficult to meet the needs of large-scale production.

[0006] 2. Poor bending process compatibility, difficult to adapt to complex structure:

[0007] The boat frame needs to realize local roll bending, angle bending, arc forming and other types of processing, and the traditional equipment can only complete single bending, which needs to be matched with multiple equipment, resulting in cumulative error of process connection, and cannot meet the sealing requirements of the boat frame curved surface.

[0008] 3. Time-consuming mold replacement, insufficient flexible production capacity:

[0009] The customization demand for boat frame types in the agricultural machinery market is increasing, but the traditional bending mold replacement needs to disassemble the bolts and calibrate the positioning, and the replacement of a single mold takes more than 1 hour, and the production economy of small batch orders is extremely poor.

[0010] 4. Much manual intervention, poor processing precision and consistency:

[0011] When relying on manual positioning of the plate, the bending angle error is large, and the experience difference of the operators leads to insufficient qualified rate of the same batch of products, especially in the processing of low rigidity materials such as aluminum alloy, which is prone to defects such as warping and wrinkling.

[0012] 5. Single clamping and supporting mode, limited adaptability:

[0013] The existing clamp can only realize one-way clamping, and for wide or irregular cross-section boat frame plates, it is easy to cause processing deviation due to unstable clamping, resulting in high scrap rate.

[0042] Compared with the prior art, the beneficial effects of the present application are:

[0043] I. Full-process automation operation, greatly improving production efficiency.

[0044] Specifically, the present application integrates full-process automation control of conveying, positioning, clamping and bending;

[0045] The device can realize continuous bending conveying: a plurality of conveying rollers are driven to rotate synchronously by a conveying drive motor through chain wheel transmission, realizing rapid horizontal conveying of the boat frame, and multiple bending can be completed at a time.

[0046] The device can realize intelligent positioning and lifting: the lifting cylinder drives the lifting plate to accurately eject the plate, and the position feedback of the integrated electric control module ensures that the positioning error of the plate at each station is less than ±0.1mm;

[0047] The device can realize multi-station cooperative operation: four sliding seats complete four bending operations in turn, and the longitudinal movement of the sliding seat is driven by a threaded screw rod, realizing continuous processing and reducing the waiting time of traditional single-station equipment.

[0048] II. Modular design and rapid mold changing, enhancing processing flexibility

[0049] The device is provided with multiple types of bending mechanisms: local roll bending is realized by the combination of the rotating bending roller and the bending arc plate of the first sliding seat, angle bending is realized by the combination of the upper and lower dies of the second and fourth sliding seats, and circular arc forming is realized by the bending roller pair of the third sliding seat, covering the processing requirements of complex curved surfaces of the boat frame;

[0050] The device is provided with a quick-release mold system: all bending parts (such as rotating bending rollers and bending lower dies) support quick plug-in replacement, and the cooperative positioning of the limiting slide rail and the electric telescopic cylinder can complete mold switching within 5 minutes, significantly shortening the production changeover time;

[0052] III. High-precision transmission and dynamic control ensure machining quality.

[0053] This device employs a precision positioning mechanism: the screw thread and the guide frame work together to achieve high linearity in the movement of the slide block, and the rolling contact between the limiting roller and the outer wall of the guide frame effectively suppresses lateral offset.

[0054] This device adopts dynamic bending control: the rotation drive motor drives the rotating bending roller to rotate, while the bending arc plate is pressed down. Through the synchronous movement of the two, the progressive rolling bending of the machine-cultivated boat frame is achieved, avoiding stress concentration and surface damage caused by traditional stamping bending.

[0055] This device can achieve real-time monitoring and compensation: the integrated electronic control module monitors the position and bending force of the plate in real time through sensors, and automatically adjusts the sliding seat displacement and pressure parameters in combination with the preset bending path model to ensure that the bending angle error is ≤ ±0.5°.
