[0020] Please refer to Figures 1-5 As shown, a tooling fixture for the automatic production of clamps includes: a bottom plate 1, a conveying mechanism is arranged inside the bottom plate 1, and a bending mechanism and a spraying assembly are arranged on the top of the bottom plate 1; The bending mechanism includes a vertical plate 11, a rotating frame 12, a discharge groove 13, a conveyor belt 14, a limiting rod 15, an opening groove 16, a limiting plate 17, a counterweight 18, a driving shaft 19, a second motor 20, a pushing block 22, an arc groove 23, a magnet block 24 and a discharge hole 25. The vertical plate 11 is fixedly installed on the top of the bottom plate 1, the second motor 20 is fixedly installed on the rear outer wall of the vertical plate 11, the output end of the second motor 20 is fixedly connected to the driving shaft 19, the front end of the driving shaft 19 is fixedly connected to the rotating frame 12, the outer wall of the rotating frame 12 is provided with an opening groove 16 and an arc groove 23, and the arc groove 23 is located inside the opening groove 16. An outlet groove is also opened inside the rotating frame 12. One end of the discharge groove 13 is communicated with the outlet groove. The bottom wall of the opening groove 16 is provided with a discharge hole 25. The bottom wall of the opening groove 16 is embedded with a magnet block 24 and is located in the middle of the discharge hole 25 and the arc groove 23. The bottom wall of the opening groove 16 is fixedly installed with a limiting plate 17. A waste material groove 4 is movably arranged on the top of the bottom plate 1 and is located below the discharge groove 13. The top of the vertical plate 11 can be externally connected to a bending machine and a punching and cutting machine. The bending machine is composed of a hydraulic push rod and a die. The hydraulic push rod drives the die to move down, so as to apply pressure to bend the clamp raw material. At the same time, cutting plates are arranged on both sides of the die and are adapted to the limiting plate 17, and can extrude and cut the clamp raw material, so that the size of the clamp raw material is more accurate. A punching column can be installed at the bottom of the die, and the two ends of the clamp can be punched. An installation groove is opened inside the rotating frame 12 and is located inside the arc groove 23. One side of the counterweight 18 is provided with a pushing block 22. The counterweight 18 is slidably connected to the installation groove. The punching waste can enter the discharge groove 13 through the discharge hole 25 and is finally discharged into the waste material groove 4 under the action of gravity.

[0021] Specifically, by setting up a bending mechanism, during use, turn on the second motor 20 to drive the rotating frame 12 to rotate, so that the clamp can rotate along a preset path, and then use an extrusion bending machine to drive the bending operation.

The limiting plate 17 can limit both sides of the clamp to make its size more accurate. When the clamp rotates to the bottom of the rotating frame 12, the counterweight block 18 moves downward under the action of gravity, thereby driving the push block 22 to move downward, and then the clamp can be pushed for blanking, so that the clamp is separated from the magnet block 24, and thus automatic blanking operation can be realized. During feeding, the raw material can be directly placed inside the limiting plate 17, so that the raw material of the clamp is fixed by magnet adsorption, and the installation is relatively convenient and fast, greatly improving the operation efficiency of the staff and being conducive to improving the production efficiency.

[0022] In this embodiment, support legs 2 are fixedly installed at the bottom of the bottom plate 1, and foot pads 3 are fixedly installed at the bottom ends of the support legs 2.

[0023] Specifically, an external power supply of the device provides electrical energy for the device. The device is externally connected to a controller, and the controller is electrically connected to a material pump, an electric push rod 8, and a motor.

[0024] The conveying mechanism includes a limiting rod 15, a first motor 5, a conveying shaft 32, conveying rollers 33 and a conveyor belt 14. A conveying groove is opened at the top of the bottom plate 1. The first motor 5 is fixedly installed at the front of the bottom plate 1. The front and rear ends of the conveying shaft 32 are respectively movably inserted into the inside of the bottom plate 1. The output end of the first motor 5 is fixedly connected to the front end of one side of the conveying shaft 32. The conveying rollers 33 are fixedly sleeved on the outside of the conveying shaft 32. The conveyor belt 14 is movably sleeved on the outside of the conveying rollers 33. The limiting rod 15 is fixedly installed at the top of the bottom plate 1 and is located on both the front and rear sides of the conveyor belt 14.

[0025] Specifically, during use, turn on the switch of the first motor 5, so that the conveying shaft 32 drives the conveying rollers 33 to rotate, and then the conveyor belt 14 can rotate, and then the clamp can be conveyed. The limiting rod 15 can limit the conveying direction of the clamp to prevent it from shifting.

[0026] The spraying assembly includes support columns 6, a paint tank 7, an electric push rod 8, a feed hopper 9, a protective cover 10, a first material pump 26, a second material pump 27, a conveying pipe 28, a first spray head 29, a second spray head 30 and an aggregate plate 31. The support columns 6 are fixedly installed at the top of the bottom plate 1 and are located on the front and rear sides of the limit rod 15. The paint tank 7 is fixedly installed on the top of the support columns 6. The feed hopper 9 is fixedly installed on the top of the paint tank 7. Both the electric push rod 8 and the first material pump 26 are fixedly installed on the outer wall of one side of the paint tank 7. The aggregate plate 31 is embedded inside the protective cover 10. The first material pump 26 is connected to the aggregate plate 31 inside the protective cover 10 through a hose. The second spray head 30 is fixedly installed inside one side wall of the aggregate plate 31. The output end of the electric push rod 8 is fixedly connected to the protective cover 10. The second material pump 27 is fixedly installed at the bottom of the paint tank 7. The output end of the second material pump 27 is connected to the conveying pipe 28. The spray head is connected to the bottom end of the conveying pipe 28.

[0027] Specifically, turn on the switch of the electric push rod 8, so that the protective cover 10 moves, and then the protective cover 10 can be sleeved outside the limit plate 17. Then turn on the switch of the first material pump 26, so that the paint is transported to the aggregate plate 31 through the first material pump 26 and the hose and then sprayed out by the second spray head 30 to spray one side surface of the clamp. The protective cover 10 can prevent the paint from spreading, making the spraying cleaner and neater. When the clamp falls onto the conveyor belt 14 for conveying, the unsprayed side surface direction of the clamp is upward. Then turn on the switch of the second material pump 27, so that the first spray head 29 can spray the surface of the clamp, thus realizing the automatic spraying use of the surface of the clamp, without manual placement, and achieving efficient automatic spraying.

[0028] In summary, compared with the prior art, the clamp production equipment has at least the following beneficial effects: By providing a bending mechanism, when in use, turn on the motor two 20 to drive the rotating frame 12 to rotate, so that the clamp can rotate along a preset path. Then use an extrusion bending machine to drive for bending operation. The conveying mechanism is responsible for conveying the bent clamp to the required position. After the bending and other operations are completed, the magnet block 24 adsorbs the clamp to prevent it from falling during rotation. The limit plate 17 can limit both sides of the clamp to make its size more accurate. When the clamp rotates to the bottom of the rotating frame 12, the counterweight block 18 moves downward under the action of gravity, thus driving the push block 22 to move downward, and then the clamp can be pushed for blanking, so that the clamp is separated from the magnet block 24, and then the automatic blanking operation can be realized. When loading, the raw material can be directly placed inside the limit plate 17, so that the clamp raw material is fixed by magnet adsorption, and the installation is more convenient and fast, greatly improving the operation efficiency of the staff and being beneficial to improving the production efficiency.
