Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing, and in particular to an automatic mechanical device for flattening punches. Background Technology
[0002] Flattening is a metal processing technique that uses the powerful pressure of a punch press to press metal materials (such as bars, wires, etc.) through a die, changing their shape and flattening them under pressure. This process is widely used in industries such as hardware manufacturing for the production of flat metal parts or for material pretreatment.
[0003] An automatic flattening machine for punch presses is a device that can automatically flatten metal materials. It mainly consists of a punch press body, a feeding mechanism, and a die device. The feeding mechanism transports the metal material to the bottom of the punch press die. Then, the punch press slide drives the upper die to move downward, applying huge pressure to the material. Under the pressure, the die causes the metal material to undergo plastic deformation, thereby flattening the material. After that, the material is automatically ejected, ready for the next round of flattening operation.
[0004] In existing technologies, some automatic flattening machines for punch presses rely on a combination of multiple independent machines and manual operation for traditional punch press flattening operations. The material loading process requires manual placement of materials one by one into the punch press working area, which is not only inefficient but also makes it difficult to ensure the accuracy of the loading position each time, resulting in unstable quality of subsequent stamping processing. After stamping, the unloading process is also labor-intensive, and manual operation is prone to safety accidents due to fatigue or negligence, resulting in low production efficiency and unstable product quality. At the same time, manual unloading is prone to safety accidents, increasing production risks and management costs. Therefore, an automatic flattening machine for punch presses is proposed to solve the above problems. Utility Model Content

The conveyor belt 6 transports the flattened material from the stamping machine 5 to the unloading machine 7 for further processing. The unloading machine 7 is set at the rear top of the conveyor belt 6. The unloading machine 7 unloads the flattened material from the conveyor belt 6. An unloading assembly is fixedly connected to the inner wall of the unloading machine 7. A fixing plate 8 is fixedly connected to the middle front side of the unloading machine 7 and the middle front side of the stamping machine 5. The fixing plate 8 provides an installation base for the flipping assembly. A flipping assembly for flipping the material is fixedly connected to the top of the fixing plate 8. The flipping assembly uses two finger cylinders 13 to grip the material. The motor 9 rotates the two finger cylinders 13 180 degrees, which can transfer the material from one conveyor belt to another.
[0036] The flipping assembly includes a motor 9, which is the power source for the flipping assembly. A rotating platform 12 is fixedly connected to the drive end of the motor 9. The rotating platform 12 rotates through the motor 9. A connecting ring 11 is fixedly connected to the top of the rotating platform 12. The connecting ring 11 connects the rotating ring 10 and the rotating platform 12. The rotating ring 10 is fixedly connected to the top of the connecting ring 11. The rotating ring 10 provides additional support to the rotating platform 12 through the connecting ring 11. Finger cylinders 13 are fixedly connected to the left and right sides of the bottom of the rotating platform 12. The finger cylinders 13 grip the material. The feeding assembly includes a vibrating plate 14. Multiple eccentric vibrators are installed at the bottom of the vibrating plate 14, which can generate centrifugal force at high speed, thereby causing the vibrating plate 14 to vibrate. A discharge port 15 is fixedly connected to the rear side of the vibrating plate 14. The material is discharged to the conveyor belt 2 3 through the discharge port 15. A vibration power supply 16 is fixedly connected to the left side of the feeding machine 4. The vibration power supply 16 is the power source for the feeding machine 4.

The unloading assembly includes a base 22, which provides support for the unloading assembly such as the motor 23.
[0038] Multiple bases 22 are each fixedly connected to the front of a second motor 23. The second motor 23 is the rotation source for 180-degree rotation. Through the rotation of the second motor 23, it docks with the next set of unloading assembly motors 23, etc. A U-shaped frame 24 is fixedly connected to the drive end of the second motor 23. The U-shaped frame 24 provides support for the second finger cylinder 25. The second finger cylinder 25 is fixedly connected to the inner wall of the U-shaped frame 24. The second finger cylinder 25 enables the opening and closing action of the gripper 26. The drive end of the second finger cylinder 25 is fixedly connected to... There are grippers 26, and the opening and closing range of grippers 26 is realized by finger cylinder 25 to adapt to the unloading needs of materials of different sizes and shapes. The inner wall of the unloader 7, i.e. the bottom of multiple grippers 26, is fixedly connected to receiving boxes 27. The receiving boxes 27 prevent materials from being caught by accidental drops during the docking of multiple unloading components. An inclined plate 28 is provided on the right side of one of the U-shaped frames 24, i.e. the inner wall of the unloader 7, to guide the material to slide into the receiving box 27 or other designated collection areas after the grippers 26 release the material.

The outer part of rotating ring 10 is rotatably connected to the inside of fixed plate 8, so that rotating ring 10 rotates within fixed plate 8. During the rotation of rotating table 12, rotating ring 10 and connecting ring 11 provide support and limit guidance for rotating table 12. Vibrating plate 14 is externally fixedly connected to the middle of the inner wall of feeding machine 4, providing support force and stability for vibrating plate 14.
[0040] After being vibrated by the vibrating plate 14, the conveyor belt 23 is transported through the discharge port 15. Under the action of vibration, the material slides onto the conveyor belt 23. The starting end of the conveyor belt 23 is tightly connected to the discharge port 15. The electric push plate 17 is fixedly connected to the middle right side of the stamping machine 5. The electric push plate 17 provides a fixing function. The bottom of the upper mold 19 and the top of the lower mold 21 are in contact. The upper mold 19 and the lower mold 21 are in close contact during the stamping process to form a closed stamping space to realize the plastic deformation processing of the material.
[0041] Working principle: In use, based on the workbench 1, the top left conveyor belt 2, the front conveyor belt 3, and the right middle conveyor belt 6 are interconnected. The feeder 4 on the top front of the second conveyor belt 3 supplies material to the second conveyor belt 3 through the internal vibrating plate 14 and the discharge port 15, realizing automated feeding. The stamping machine 5 flattens the material with the help of the stamping components. Finally, the unloading machine 7 on the top rear of the third conveyor belt 6 uses the unloading components to unload and transfer the material. All components work closely together and operate in an orderly manner under the overall control of the control device, forming a complete and efficient automated production line, which greatly improves production efficiency and quality stability.
[0042] Conveyor belt 2 transports materials to the stamping area and transfers the stamped materials to conveyor belt 3 6. Conveyor belt 3 connects the feeder 4 and conveyor belt 2 to facilitate material transfer. When materials need to be exchanged between the two conveyor belts, motor 9 drives the rotating table 12 to rotate. The finger cylinders 13 on both sides of its bottom grip the materials. At the same time, the rotating table 12 drives the connecting ring 11 and the rotating ring 10 to rotate inside the fixed plate 8, providing support and limiting the rotating table 12, allowing it to rotate 180 degrees. This achieves flexible material transfer between the two conveyor belts and effectively enhances the adaptability of the device to complex processes.
