Description

Technical Field

[0001] This invention relates to the field of gate steel plate processing technology, specifically a CNC bending processing device for hydraulic gate steel plates. Background Technology

[0002] As a core control component of water conservancy projects, hydraulic gates require key load-bearing and sealing parts (such as valve bodies, flanges, and gate plates) to possess specific arc curvatures, angles, or irregular contours. They must withstand harsh conditions such as high-pressure water flow and water hammer impacts over long periods, while also adapting to different diameters and complex installation scenarios. Flat steel plates cannot directly form the valve's working cavity, and their pressure resistance and deformation resistance are limited. Bending processes, however, allow steel plates to form an "arch"-shaped load-bearing structure, dispersing external pressure, increasing rigidity, reducing welding joints, and lowering leakage risks. Therefore, hydraulic gate steel plates must undergo precise bending processing. The CNC bending processing device for hydraulic gate steel plates is an automated processing equipment specifically designed for this requirement. Through a CNC system, it precisely controls the bending angle and curvature to achieve integrated forming of the steel plate. Its core function is to meet the structural forming requirements of valve components, improve pressure and impact resistance, optimize production processes, and adapt to diverse specifications, providing a high-quality processing foundation for the safe and stable operation of hydraulic gates.

[0003] However, existing processing equipment suffers from poor processing continuity. Feeding, bending, and demolding require separate operations, necessitating machine downtime and waiting, resulting in low production efficiency. At the same time, poor demolding performance leads to difficulties in picking up parts, affecting the processing rhythm. Furthermore, it cannot achieve continuous automatic conveying of steel plates, which not only increases labor costs but also makes it easy for human error to affect processing accuracy.

[0014] The beneficial effects of this invention are: (1) The present invention can transport steel plates to the lower mold through the unloading component. The hydraulic rod is activated to drive the lifting plate 1 to descend. The lowering plate 1 can bend the steel plate inside the lower mold through the upper mold. After bending, as the lifting plate 1 rises, the lifting rack plate can drive the gear to rotate. The gear rotation can drive the rotating shaft to rotate through the cooperation of the baffle 2, spring 2 and spring 2. Then, the conveyor belt can be driven to run through the chain wheel group and drive roller 1. The operation of the conveyor belt can drive the drive roller 2 to rotate. When the drive roller 2 rotates, the cooperation of the baffle 1, spring 1 and ratchet groove 1 can prevent the drive shaft from rotating synchronously with the drive roller 2, thus avoiding damage to the motor 1. At the same time, the operation of the conveyor belt can drive the lower mold to move, thereby realizing its movement from the loading station to the processing station and the unloading station, ensuring the continuity of processing, thereby improving processing efficiency.

[0015] (2) After the steel plate on the lower mold of the present invention is processed, when it moves to the unloading station, the trapezoidal block can drive the lifting plate two to rise. The rise of the lifting plate two can drive the lifting rod to rise, and then drive the lifting block to rise and push the processed steel plate out from the inside of the lower mold, so as to facilitate the removal of the steel plate. As the lower mold continues to move, when it reaches the unloading station, the trapezoidal groove, the moving rod and the limiting plate and the reset spring can make the impact head move repeatedly, thereby knocking the lower mold and ensuring that the steel plate inside the lower mold falls off smoothly.

[0016] (3) The present invention can drive the pulley group to run through the second motor, and then drive the push block to move through the second mounting block, the moving plate and the push plate. The push block can push the steel plate inside the placement plate to the inside of the unloading plate, so that it can be transported to the lower mold in the loading station. During the transportation process, the electric push rod can drive the support block to rise to support the steel plate that has not been transported, so as to ensure that the steel plate inside the placement plate has strong stability. Since the push plate and the push block are trapezoidal, when they move to a certain extent, the steel plate at the top of them begins to slowly descend. At the same time, the electric push rod drives the support block to descend, so that the steel plate slowly descends inside the placement plate. Through the cooperation of the unloading components, it can ensure that the steel plate can be continuously transported to the inside of the lower mold, reducing manual intervention and improving work efficiency.

The controller regulates the extension stroke and pressure of hydraulic rod 18, and the front display shows the processing parameters in real time to ensure bending accuracy. Hydraulic rod 18 drives the lifting plate and upper mold 12 to lift and lower, providing sufficient pressure for bending processing. Conveying device 19 receives the bent workpiece that falls off the unloading station and transports it to the subsequent process to achieve automated unloading. Support pad 20 provides stable support for the device, reduces vibration during processing, prevents equipment displacement, and ensures bending accuracy.

[0029] Working principle of the invention: Before processing, the steel plates 62 to be processed are neatly stacked in the placement plate 61. After the unloading component 6 is started, the motor 65 drives the pulley group 64 to rotate. The moving plate 67, push plate 68 and push block 69 are driven to move smoothly along the T-shaped slide 71 through the mounting block 66. The push block 69 pushes the bottom steel plate 62 to the lower loading plate 63. At the same time, the electric push rod 74 drives the support block 73 to rise, supporting the steel plate 62 to keep it stable. Under the guidance, it falls accurately into the lower mold 13 in the loading station. As the push plate 68 and push block 69 move, their trapezoidal structure drives the upper steel plate 62 to slowly descend. The electric push rod 74 drives the support block 73 to move down in sync, ensuring a continuous supply of subsequent steel plates 62 and reducing manual intervention. After the material is loaded, the press 17 is started, and the hydraulic rod 18 extends to push the lifting plate 11 and the upper die 12 at the bottom to descend, cooperating with the lower die 13 to apply pressure to the steel plate and complete the bending process. During the bending process, the lower die 13 is fixed to the conveyor belt 21 by the mounting block 14 to ensure processing stability. After processing, the hydraulic rod 18 retracts to drive the lifting plate 11 to rise, and simultaneously drives the lifting rack plate 31 on one side to rise, meshing with the gear 32 to drive the rotating shaft 33 to rotate. At this time, the baffle 35 inside the rotating shaft 33 abuts against the ratchet groove 37 under the action of the spring 36 to achieve unidirectional transmission and avoid damage to the components by reverse force; the rotating shaft 33 drives the drive roller 22 to rotate through the chain wheel group 34, which in turn drives the conveyor belt 21 to run, and drives the lower die 13 to move from the processing station to the material loading station. At the same time, the subsequent unloaded lower die 13 moves synchronously to the processing station, and the new steel plate 62 falls into the lower die 13 through the unloading assembly 6 to achieve continuous processing.

[0030] As the lower mold 13 moves to the unloading station, its bottom lifting plate 42 contacts the trapezoidal block 41 on the frame 1. The trapezoidal block presses the lifting plate 42 upward, and the lifting rod 43 drives the lifting block 44 to lift the bent workpiece, completing the initial demolding. As the lower mold continues to move, its internal trapezoidal groove 51 presses the impact head 52, driving the moving rod 53 and the limiting plate 54 to compress the return spring 55. When the return spring rebounds, it drives the impact head to strike the lower mold in the opposite direction, shaking off the adhered workpiece and ensuring that the workpiece is completely detached to the conveying device 19 below, from which it is transferred to the subsequent process. In this process, the entire processing is seamlessly connected through continuous material feeding by the unloading component, precise bending by the stamping machine, station switching driven by the rotating component, and workpiece detachment and vibration components. This achieves automated and continuous bending processing of hydraulic gate steel plates, significantly improving production efficiency and processing accuracy, and reducing errors and safety hazards caused by manual intervention.
