Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a self-locking bending mechanism for a bending machine. Background Technology

[0002] The bending machine is a specialized piece of equipment designed for high-precision bending of metal sheets. It integrates hydraulic drive and a mechanical-hydraulic composite self-locking mechanism. Through a servo hydraulic system, it precisely controls the slider to drive the bending cutter downwards to complete the bending of the sheet metal. When the slider reaches the set bending position, the self-locking component can automatically lock the slider, effectively preventing the slider from rebounding or accidentally sliding down due to hydraulic leakage or pressure fluctuations. At the same time, it can achieve emergency locking in case of power failure, hydraulic failure, or other emergencies, ensuring both high precision and consistency of bending angles and significantly improving the safety of equipment operation.

[0003] Patent publication number "CN222957249U" discloses "A self-locking bending mechanism for a bending machine, comprising a worktable, an inverted L-shaped plate fixedly installed on one side of the worktable, a lower mold on the worktable, and V-shaped bending grooves at different angles opened on the four sides of the lower mold. An upper mold is provided on the inverted L-shaped plate corresponding to the lower mold, and the upper mold is mounted on the inverted L-shaped plate by several electric push rods. The key feature is that: a rotating shaft is fixedly installed at both ends of the lower mold, and a U-shaped plate is fitted around the outer periphery of the rotating shaft. The rotating shaft and the corresponding U-shaped plate are inserted and fitted together, and the U-shaped plate is fixedly installed on the worktable. L-shaped plates that can limit the movement of the lower mold are fitted together on both sides. This utility model has a simple structure and ingenious design. When it is necessary to rotate the lower mold, it is only necessary to release the limiting effect of the L-shaped plate on the lower mold. There is no need to add lifting equipment to lift the lower mold, which reduces the cost of the device. At the same time, it is simple to operate, saves time and labor, meets practical needs, and is suitable for promotion."

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4This application provides a self-locking bending mechanism for a bending machine, including a worktable 1. A self-locking component 2 is fixedly installed on the top of the worktable 1, and a bending component 3 is fixedly installed on the top of the self-locking component 2. A control panel 4 is fixedly installed on one side of the worktable 1, and a length-fixing component 5 is fixedly installed on the top of the worktable 1. The self-locking component 2 includes a support frame 21 and a cylinder 22. The support frame 21 is fixedly installed on the top of the worktable 1, and the cylinder 22 is fixedly installed on the top of the support frame 21. A lifting frame 23 is fixedly connected to the output end of the cylinder 22, and a clamping block 24 is fixedly installed at the bottom of the lifting frame 23. The top of the worktable 1 is fixedly... A clamping block 25 is fixedly installed, and a workpiece plate 26 is provided on the top of the clamping block 25. The workpiece plate 26 is located below the bending assembly 3. A control panel 4 is fixedly installed on one side of the worktable 1. The control panel 4 is electrically connected to the cylinder 22. The self-locking assembly 2 also includes a stabilizing rod 27, which is fixedly connected to the top of the lifting frame 23. The stabilizing rod 27 is slidably connected to the support frame 21. The bending assembly 3 includes a cylinder 31 and a bending block 32. The cylinder 31 is fixedly installed on the top of the support frame 21. The bending block 32 is fixedly connected to the output end of the cylinder 31. The control panel 4 is electrically connected to the cylinder 31.

[0033] In this embodiment, before operation, the workpiece plate 26 is placed on top of the clamping block 25 of the workbench 1. The length-fixing component 5 is started through the control panel 4. The motor 52 drives the bidirectional threaded rod 53 to rotate, which drives the two moving blocks 54 on both sides to move synchronously along the fixed frame 51. The moving blocks 54 are driven by the connecting rod 55 to push the length-fixing plate 56 to smoothly adhere to both sides of the workpiece plate 26, completing the length-fixing limit. The stabilizing block 57 restricts the movement trajectory of the moving blocks 54 to avoid deviation and ensure the length-fixing accuracy. After the length-fixing is completed, the control panel 4 sends a command to the cylinder 22 of the self-locking component 2. The cylinder 22 drives the lifting frame 23 to slide down along the stabilizing rod 27. The stabilizing rod 27 slides and cooperates with the support frame 21 to improve the movement stability of the lifting frame 23 until the clamping block 24 at the bottom of the lifting frame 23 presses the workpiece plate 26, realizing the firm self-locking of the workpiece and preventing the workpiece from moving or shifting during bending. After locking is completed, the control panel 4 triggers the action of cylinder 31 of bending assembly 3. Cylinder 31 drives bending block 32 to move downward. Bending block 32 applies pressure to the self-locked workpiece plate 26 to complete the bending operation at the preset angle. The electrically controlled cylinder 31 can accurately control the bending force and stroke to ensure the bending forming effect. After the bending operation is completed, the control panel 4 sends reset commands in sequence. Cylinder 31 first drives bending block 32 to reset upward. Then, cylinder 22 drives lifting frame 23 to slide upward along stabilizer bar 27. Clamping block 24 releases workpiece plate 26 and releases self-locking. The control panel 4 is a Weintek MT8071iE, cylinder 22 is an Airtac SC63×50-S, cylinder 31 is an Airtac MI40×80-S-CA, and motor 52 is a Panasonic MHMJ042G1U.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the length-fixing component 5 includes a fixed frame 51 and a motor 52. The fixed frame 51 is fixedly installed on the top of the workbench 1, and the motor 52 is fixedly installed on one side of the fixed frame 51. The output end of the motor 52 is fixedly connected to a bidirectional threaded rod 53. A moving block 54 is threadedly connected to the side wall of the bidirectional threaded rod 53. The length-fixing component 5 also includes a connecting rod 55, which is hinged to one side of the moving block 54. The other end of the connecting rod 55 is hinged to a length-fixing plate 56. The length-fixing component 5 also includes a stabilizing block 57, which is fixedly installed on one side of the moving block 54. The stabilizing block 57 is slidably connected to the fixed frame 51. Four support blocks 6 are fixedly installed at the bottom of the workbench 1, and the four support blocks 6 are arranged opposite to each other.

[0035] In this embodiment, the motor 52 of the final length-fixing component 5 rotates in the reverse direction, driving the bidirectional threaded rod 53 to reset. The moving block 54 pulls the length-fixing plate 56 away from the workpiece plate 26 through the connecting rod 55, releasing the length-fixing limit. The operator can then remove the formed workpiece plate 26, completing a complete bending operation cycle. The entire process is centrally controlled by the control panel 4, and all components move smoothly together. The four support blocks 6 at the bottom of the workbench 1 provide stable support, preventing equipment shaking from affecting processing accuracy. In this case, the thread helix angle is less than or equal to the equivalent friction angle.

[0036] Working principle: Before operation, the workpiece plate 26 is placed on top of the clamping block 25 of the workbench 1. The length-fixing component 5 is started through the control panel 4. The motor 52 drives the bidirectional threaded rod 53 to rotate, which drives the moving blocks 54 on both sides to move synchronously along the fixed frame 51. The moving blocks 54 push the length-fixing plate 56 to smoothly adhere to both sides of the workpiece plate 26 through the connecting rod 55, thus completing the length-fixing limit. The stabilizing block 57 restricts the movement trajectory of the moving blocks 54 to avoid deviation and ensure the length-fixing accuracy. After the length is fixed, the control panel 4 sends a command to the cylinder 22 of the self-locking component 2. The cylinder 22 drives the lifting frame 23 to slide down along the stabilizing rod 27. The stabilizing rod 27 slides and cooperates with the support frame 21 to improve the movement stability of the lifting frame 23 until the clamping block 24 at the bottom of the lifting frame 23 presses the workpiece plate 26, realizing the firm self-locking of the workpiece and preventing the workpiece from moving or deviating during the bending process.

[0037] After the workpiece self-locking is completed, the control panel 4 triggers the action of cylinder 31 of bending assembly 3. Cylinder 31 drives bending block 32 to move downward. Bending block 32 applies pressure to the self-locked workpiece plate 26 to complete the bending operation at the preset angle. The electrically controlled cylinder 31 can precisely control the bending force and stroke to ensure the bending forming effect. After the bending operation is completed, the control panel 4 sends reset commands in sequence. Cylinder 31 first drives bending block 32 to reset upward, and then cylinder 22 drives lifting frame 23 along stabilizer bar 27. Slide upwards, clamping block 24 releases workpiece plate 26, releasing self-locking. Finally, motor 52 of fixed length component 5 rotates in the reverse direction, driving bidirectional threaded rod 53 to reset. Moving block 54 pulls fixed length plate 56 away from workpiece plate 26 through connecting rod 55, releasing fixed length limit. Operator can then remove the formed workpiece plate 26, completing a complete bending operation cycle. The entire process is centrally controlled by control panel 4, with smooth linkage between components. The four support blocks 6 at the bottom of worktable 1 provide stable support, preventing equipment shaking from affecting processing accuracy.
