DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, the present invention provides a full-electric servo bending machine, comprising a machine body 1;

[0029] A pressing tool 2 is arranged on the front side of the machine body 1;

[0030] The left and right sides of the machine body 1 are movably connected with a rocker arm 3 through a pin shaft, and the left and right sides of the pressing tool 2 are fixedly connected with an extension plate 4, which extends to the inner side of the rocker arm 3 away from the pressing tool 2, and the surface of the extension plate 4 is fixedly connected with a slide bar 5 located inside the rocker arm 3, and the slide bar 5 is slidably connected to the rocker arm 3. A transmission structure 6 is arranged inside the machine body 1, and the transmission structure 6 can drive the rocker arm 3 to swing and use the lever principle to push the slide bar 5 to rise and fall vertically.

[0031] refer to Figure 3 The transmission structure 6 includes an opening 7 opened on the surface of the body 1, and a lifting plate 8 is slidably connected to the inside of the opening 7. Both sides of the lifting plate 8 are fixedly connected to brackets 9 located inside the rocker 3. The surface of the bracket 9 is fixedly connected to a push rod 10 located inside the rocker 3. The push rod 10 is slidably connected to the rocker 3. A servo motor 11 is fixedly connected to the top of the body 1. A screw 12 is fixedly connected to the output end of the servo motor 11. The output end of the screw 12 passes through the body 1 and extends to the inside of the opening 7. The lifting plate 8 is sleeved on the surface of the screw 12 and is threadedly connected to the screw 12.

[0032] As a technical optimization solution of the present invention, the design of the transmission structure 6 enables the swing of the rocker arm 3 to be precisely controlled by the servo motor 11, realizing automation and intelligence. The threaded connection between the screw 12 and the lifting plate 8 ensures the stability and reliability of the lifting movement. The setting of the bracket 9 and the push rod 10 enables the movement of the lifting plate 8 to be converted into the swing of the rocker arm 3, thereby driving the sliding rod 5 to rise and fall.

[0033] refer to Figure 1 A limiting groove 13 is provided on the surface of the pressing tool 2, and a limiting rod 14 located inside the limiting groove 13 is fixedly connected to the front of the body 1, and the limiting rod 14 is slidably connected to the limiting groove 13.

[0034] As a technical optimization solution of the present invention, the motion trajectory of the pressing tool 2 is limited by the design of the limiting groove 13 and the limiting rod 14, thereby preventing errors or damage caused by unstable motion. This design improves the processing accuracy and stability of the bending machine.

[0035] refer to Figure 3 The left and right sides of the machine body 1 are fixedly connected with connecting blocks 15, and the inner side of the connecting block 15 is movably connected with a protective frame 16 through a pin shaft. The side of the protective frame 16 away from the connecting block 15 can extend to the front of the machine body 1.

[0036] As a technical optimization solution of the present invention, the design of the protective frame 16 plays a role in safety protection, which can prevent the operator from being accidentally injured during the bending process. At the same time, the protective frame 16 is movably connected by a pin shaft and can be easily opened or closed, which is convenient for operation and maintenance.

[0037] refer to Figure 3 The top of the protection frame 16 and the outer side of the swing rod 3 are fixedly connected with a bevel gear 17, and the bevel gears 17 are meshed with each other.

[0038] As a technical optimization solution of the present invention, the mutual engagement of the bevel gears 17 enables the swing of the rocker arm 3 to drive the synchronous swing of the protective frame 16, thereby ensuring the relative position relationship between the protective frame 16 and the pressing tool 2, which not only improves the safety of the bending machine, but also makes the opening and closing of the protective frame 16 more flexible and convenient.

[0039] refer to Figure 3 A spring plate 18 is fixedly connected to the surface of the protection frame 16 , and a side of the spring plate 18 away from the protection frame 16 can contact the front side of the body 1 , and the spring plate 18 is elastic.

[0040] As a technical optimization solution of the present invention, the design of the spring plate 18 plays a role of buffering and shock absorption, which can reduce the impact and noise between the protective frame 16 and the front of the body 1 when it is closed. At the same time, the elasticity of the spring plate 18 also ensures the close contact between the protective frame 16 and the body 1, preventing the entry of dust and debris.

[0041] The working principle and use process of the present invention are as follows: when a bending task needs to be performed, the servo motor 11 on the top of the machine body 1 is started, the servo motor 11 starts to rotate, and the screw 12 fixedly connected to its output end rotates accordingly. The rotation of the screw 12 causes the lifting plate 8 threadedly connected thereto to slide up and down in the opening 7 inside the machine body 1. Brackets 9 are fixed on both sides of the lifting plate 8. The push rod 10 on the bracket 9 slides with the sliding of the lifting plate 8 and pushes the inner part of the swing rod 3. Since the swing rod 3 is movably connected to the machine body 1 through a pin shaft, the push of the push rod 10 causes the swing rod 3 to swing around the pin shaft as the center, and the swing of the swing rod 3 drives the sliding rod 5 inside it to slide on the extension plate 4. The vertical lifting of the slide bar 5 enhances the downward pressure of the pressing tool 2 through the lever principle, thereby expanding the downward pressure strength. The pressing tool 2 moves downward under the push of the slide bar 5 to bend the workpiece placed on the workbench of the machine body 1. At the same time, connecting blocks 15 are fixed on the left and right sides of the machine body 1. The connecting blocks 15 are movably connected to the protective frame 16 through a pin shaft. When the swing arm 3 swings, the bevel gear 17 on its outside is meshed with the bevel gear 17 on the top of the protective frame 16, driving the protective frame 16 to swing around the pin shaft of the connecting block 15. When the protective frame 16 moves to the front of the machine body 1, the protective frame 16 can protect the operator from potential injuries when the pressing tool 2 moves.

[0042] In summary, the all-electric servo bending machine achieves the expansion of downward pressure strength through the cooperation of the swing rod 3 and the slide rod 5 and the drive of the transmission structure 6. The swing rod 3, as a lever, can generate a larger downward force with a smaller driving force, thereby improving the bending capacity of the bending machine. At the same time, the sliding connection between the slide rod 5 and the swing rod 3 ensures the stability and accuracy of the movement.
