[0002] During the forging process, an oxide layer will form on the surface of the bending cutter. This oxide layer needs to be cleaned before it can be used on the bending machine. There are various ways to treat the surface of the forging, including pickling.

[0003] Existing pickling equipment suffers from insufficient automation, requiring significant manual intervention, and its surface treatment efficiency needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for precision forgings in bending machines that can perform highly automated operations, has high surface treatment efficiency, and is highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A surface treatment device for precision forgings for bending machines includes a treatment tank. Inside the treatment tank, an acid pickling tank, a neutralization tank, and a rinsing tank are arranged side by side. The neutralization tank is located between the acid pickling tank and the rinsing tank. A first linear module is installed on each of the two sides of the upper end of the treatment tank. Two parallel support beams are fixedly installed between the moving ends of the two first linear modules. Two second linear modules are installed on the upper surface of each support beam. A connecting arm is fixedly installed on the moving end of the second linear module. A roller bracket is installed at one end of the connecting arm.

[0007] By adopting the above technical solution, pickling, neutralization and rinsing operations can be automatically realized, with a high degree of automation and high surface treatment efficiency.

[0008] Furthermore, the roller bracket is located between two support beams.

[0009] By adopting the above technical solution, the structural stability of the roller bracket is ensured.

[0010] Furthermore, a bracket is fixedly installed on the side surface of the treatment tank, and a connecting seat is installed on the outer surface of the bracket. The connecting seat is provided with two water outlets, and a flushing pipe is installed at each water outlet. One row of the flushing pipes is placed inside the flushing tank, and flushing holes are provided on the outer surface of the flushing pipes. The flushing holes on the two rows of flushing pipes are positioned opposite each other.

[0011] By adopting the above technical solution, the surface of forgings can be washed efficiently.

[0012] Furthermore, a mounting base is fixedly installed on the side surface of the treatment pool. Two mounting holes are provided on the outer surface of the mounting base, and an electric push rod is fixedly installed inside the mounting holes. A pusher block is installed on the telescopic end of the electric push rod.

[0013] By adopting the above technical solution, an electric push rod can be used to drive the pusher block to move, thereby realizing automatic material feeding operation.

[0014] Furthermore, a first roller conveyor and a second roller conveyor are installed on one side of the treatment tank, with the first roller conveyor and the second roller conveyor corresponding to the positions of the pickling tank and the rinsing tank, respectively.

[0015] By adopting the above technical solutions, automatic feeding and unloading operations can be achieved.

[0016] Furthermore, a submersible pump is installed at the bottom of the rinsing pool, and a drain pipe is installed at the outlet of the submersible pump.

[0017] By adopting the above technical solution, wastewater in the flushing pool can be discharged in a timely manner.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for the surface treatment of forgings by placing the forging on a roller support and then simultaneously activating multiple second linear modules using a PLC controller. The connecting arm lowers the roller support, placing the forging supported on the roller support into the pickling tank. An external monitoring system monitors the concentration and time of the pickling solution, ensuring precise pickling of the oxide layer on the forging surface. After pickling, the second linear modules raise the height of the roller support, allowing the pickled forging to be removed from the pickling tank. Then, two first linear modules are simultaneously activated, moving the support beam and roller support above the neutralization tank. Next, the roller support is lowered so that the pickled forging can be placed inside the neutralization tank. The alkaline solution inside the neutralization tank neutralizes the pickling solution remaining on the surface of the forging. After neutralization, the roller support is raised, and then the first linear module is used to move the roller support above the rinsing tank. Then the height of the roller support is lowered so that the roller support and the forging can be placed inside the rinsing tank. Then the rinsing water passes through the connecting seat and sprays out from the rinsing hole of the rinsing pipe, which can effectively rinse the surface of the forging. The entire surface treatment process of the forging does not require much manual intervention. The surface treatment has a high degree of automation and high efficiency.

[0020] 2. After rinsing, the roller support can be raised to its highest position, at which point the roller support is flush with the conveying surface of the second roller conveyor. Then, two electric push rods are extended simultaneously. The extension of the electric push rods can move the push block, which can push the processed forging onto the second roller conveyor. At this time, the second roller conveyor can be used to realize automatic unloading operation, which is highly practical. Attached Figure Description

Detailed Implementation

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

Inside the treatment tank 1, an acid pickling tank 2, a neutralization tank 3, and a rinsing tank 4 are arranged side-by-side. The neutralization tank 3 is located between the acid pickling tank 2 and the rinsing tank 4. A first linear module 5 is installed on each of the two upper edges of the treatment tank 1. Two parallel support beams 8 are fixedly installed between the moving ends of the two first linear modules 5. Two second linear modules 10 are installed on the upper surface of each support beam 8. A connecting arm 11 is fixedly installed on the moving end of each second linear module 10. A roller bracket 9 is installed at one end of the connecting arm 11. The roller bracket 9 is located between the two... A bracket is fixedly installed on the side surface of the treatment pool 1 between the support beams 8, and a connecting seat 12 is installed on the outer surface of the bracket. The connecting seat 12 is provided with two water outlets, and a flushing pipe 13 is installed at each water outlet. One row of flushing pipes 13 is placed inside the flushing pool 4. The outer surface of the flushing pipes 13 is provided with flushing holes, and the flushing holes on the two rows of flushing pipes 13 are opposite to each other. Multiple second linear modules 10 are connected to the same PLC controller through a high-speed communication line. When the surface of the forging is being treated, the forging can be placed on the roller bracket 9, and then the PLC controller can be used to synchronously start multiple second linear modules. The linear module 10, at this time, connects the arm 11 to lower the roller support 9, thereby placing the forging supported on the roller support 9 into the pickling tank 2. An external monitoring system monitors the concentration and time of the pickling solution, ensuring precise pickling of the oxide layer on the forging surface. After pickling, the second linear module 10 raises the height of the roller support 9, allowing the pickled forging to be removed from the pickling tank 2. Then, the two first linear modules 5 are simultaneously activated, moving the support beam 8 and the roller support 9 above the neutralization tank 3. Finally, the roller support 9 is lowered, allowing the pickled forging to be placed in the neutralization tank. Inside the neutralization tank 3, the alkaline solution inside the neutralization tank 3 is used to neutralize the pickling solution remaining on the surface of the forging. After neutralization, the roller support 9 is raised, and then the first linear module 5 is used to move the roller support 9 above the rinsing tank 4. Then the height of the roller support 9 is lowered so that the roller support 9 and the forging can be placed inside the rinsing tank 4. Then the rinsing water passes through the connecting seat 12 and sprays out from the rinsing hole of the rinsing pipe 13, which can effectively rinse the surface of the forging. The entire surface treatment process of the forging does not require much manual intervention, and the surface treatment has a high degree of automation and high efficiency.

[0026] Reference Figure 1A mounting base 14 is fixedly installed on the side surface of the treatment tank 1. Two mounting holes are provided on the outer surface of the mounting base 14, and an electric push rod 15 is fixedly installed inside the mounting holes. A pusher block 16 is installed at the telescopic end of the electric push rod 15. A first roller conveyor 6 and a second roller conveyor 7 are installed on one side of the treatment tank 1. The first roller conveyor 6 and the second roller conveyor 7 correspond to the positions of the pickling tank 2 and the rinsing tank 4, respectively. The first roller conveyor 6 can be used to transport the forgings to be treated. The forgings are transferred to the roller bracket 9, enabling automatic feeding. After surface treatment, the roller bracket 9 is raised to its highest position, at which point it is flush with the conveying surface of the second roller conveyor 7. Then, two electric push rods 15 are extended simultaneously. The extension of the electric push rods 15 allows the pusher block 16 to move. The pusher block 16 pushes the processed forgings and pushes them onto the second roller conveyor 7. At this point, the second roller conveyor 7 enables automatic unloading, making it highly practical.

[0027] Reference Figure 1 A submersible pump 17 is installed at the bottom of the flushing tank 4. A drain pipe is installed at the outlet of the submersible pump 17. The submersible pump 17 can be used to pump out the wastewater generated inside the flushing tank 4, ensuring that the flushing operation can be carried out stably and orderly.

[0028] Working Principle: In use, the device is first installed in the designated location. Then, the first roller conveyor 6 transports the forgings to be processed onto the roller support 9, enabling automatic feeding. Next, the PLC controller synchronously starts multiple second linear modules 10. The connecting arm 11 lowers the roller support 9, placing the forgings supported on it inside the pickling tank 2. An external monitoring system monitors the concentration and time of the pickling solution, ensuring precise pickling of the oxide layer on the forging surface. After pickling, the second linear modules 10 raise the roller support 9, allowing the pickled forgings to be removed from the pickling tank 2. Then, two first linear modules 5 are synchronously started, moving the support beam 8 and roller support 9 above the neutralization tank 3. Finally, the roller support 9 is lowered, placing the pickled forgings into the neutralization tank. Inside the neutralization tank 3, the alkaline solution inside the neutralization tank 3 is used to neutralize the pickling solution remaining on the surface of the forging. After neutralization, the roller support 9 is raised, and then the first linear module 5 is used to move the roller support 9 above the rinsing tank 4. Then the height of the roller support 9 is lowered so that the roller support 9 and the forging can be placed inside the rinsing tank 4. Then the rinsing water passes through the connecting seat 12 and sprays out from the rinsing hole of the rinsing pipe 13, which can effectively rinse the surface of the forging. When the surface treatment is completed, the roller support 9 is raised to the highest position. At this time, the roller support 9 is flush with the conveying surface of the second roller conveyor 7. Then, the two electric push rods 15 are extended at the same time. The extension of the electric push rods 15 can move the pusher block 16. The pusher block 16 can push the processed forging and push the forging onto the second roller conveyor 7. At this time, the second roller conveyor 7 can realize the automatic unloading operation.
