Description

Technical Field

[0002] A bending machine is a machine that can bend sheet metal. Bending machines are divided into manual bending machines, hydraulic bending machines, and CNC bending machines. Manual bending machines are further divided into mechanical manual bending machines and electric manual bending machines. Hydraulic bending machines can be classified according to their synchronization method into torsion shaft synchronization, mechanical-hydraulic synchronization, and electro-hydraulic synchronization. Hydraulic bending machines can also be classified according to their motion method into top-moving type and bottom-moving type.

[0003] In related technologies, the invention patent with publication number CN103920759B discloses a bending machine. This bending machine can achieve automatic bending, improve work efficiency, reduce labor costs, improve operational safety, and prevent the bending machine from getting stuck at the feeding port. However, the workpiece is fed by gravity and falls to the processing position. This method makes it difficult to ensure the accurate positioning of the workpiece, which will affect the bending effect. Moreover, the frequent impact of the workpiece on the worktable will also cause damage to the surface of the worktable. Therefore, we propose a plate bending machine for processing mechanical parts.

Through the guide rail 3 and the workpiece placement device 9, the workpiece to be bent can be effectively placed and transported. The positioning baffle 10 positions the workpiece placement device 9 to improve the bending accuracy. The bending head 8 is replaceable and is suitable for various bending scenarios.

[0024] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3As shown, multiple sets of drive columns 14 are installed at equal intervals on the upper end of the conveyor belt 13. An active roller is installed on the inner side of the left end of the conveyor belt 13, and a driven roller is installed on the inner side of the right end of the conveyor belt 13. The front and rear ends of the driven roller are rotatably mounted on the inner side of the right-side fixed frame 11 via a rotating shaft. The drive columns 14 installed on the upper end of the conveyor belt 13 move with the conveyor belt 13 to drive the workpiece placement device 9 and realize automated guiding and conveying.

[0025] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, the front and rear ends of the drive roller are rotatably mounted on the inner side of the left fixed frame 11 via a rotating shaft. The front end of the drive roller is connected to the output end of the transmission motor 12 via a rotating shaft.

[0026] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, a transmission baffle 16 is vertically installed at the lower center of the workpiece placement device 9, corresponding to the position of the transmission column 14. A guide plate 15 is horizontally installed on the inner side of the clamping plate 20. The guide plate 15 is detachably installed on the clamping plate 20 via the disassembly plate 19.

When they contact the transmission baffle 16 at the lower end of the workpiece placement device 9, they will push the workpiece placement device 9 to move forward along the guide rail 3. The guide plate 15 interacts with the guide groove on the guide rail 3 to ensure that the workpiece placement device 9 maintains a straight line during movement and avoids deviation or falling off. When the workpiece placement device 9 reaches the preset position, The positioning baffle 10, controlled by the first servo motor 5, descends and inserts into the positioning groove on the guide rail 3, precisely positioning the workpiece placement device 9. The design of the positioning baffle 10 ensures the accuracy of the workpiece's position before bending, which is crucial for ensuring bending quality. The second servo motor 6 drives the bending head 8 at its lower end to move downward according to a preset program or through the operation of the controller 7. The bending head 8 can be selected according to the appropriate type and can be quickly replaced to adapt to different bending requirements. After the bending head 8 contacts the workpiece, it applies force to complete the bending operation. After bending is completed, the positioning baffle 10 rises, releasing the workpiece placement device 9. The transmission motor 12 starts again and continues to push the workpiece placement device 9 and the bent workpiece inside it along the guide rail to the next station through the transmission column 14. This cycle repeats to achieve continuous and efficient bending operations.
