Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1: An automated production line and process flow for forging cylindrical parts. Please refer to... Figures 1-3The automated production line includes equipment such as a feeding conveyor, a heating furnace, a descaling machine 3, a hydraulic press, storage bins, an electrical control and hydraulic station 6, a back-end server system 13, and robotic arms. The feeding conveyor includes feeding conveyor 1 and feeding conveyor 2 9. The heating furnace includes heating furnace 1 2 and heating furnace 2 10. The hydraulic press includes hydraulic press 1 4 and hydraulic press 2 11. There are two storage bins, storage bin 1 5 and storage bin 2 12, located on one side of hydraulic press 1 4 and hydraulic press 2 12 respectively. There are two robotic arms, robotic arm 1 7 and robotic arm 2 8. Each hydraulic press corresponds to one robotic arm; hydraulic press 1 4 corresponds to robotic arm 1, and hydraulic press 2 11 corresponds to robotic arm 2 8. Please refer to the diagram. Figure 10 In the background server system 13, there are a conveying control command module 16, a heating control command module 17, an oxidation command control module 18, and a grabbing command control module 19.

[0048] Example 2: Based on Example 1, please continue to refer to... Figures 1-3 In the process, the feeding conveyor 1 is connected to the heating furnace 2. Furthermore, the feeding conveyor 1 and the heating furnace 2 establish a communication connection through the background server system to establish an action flow. The raw material workpiece is transported to the heating furnace 2 for heating through the feeding conveyor 1 under the control command of the background server system.

[0049] Example 3: Based on Example 2, the back-end server system has a conveying command control module 16 that controls the feeding conveyor 1 to feed raw materials to the heating furnace 2 for heating via the power supply and communication module 2 15. A conveying chain device 21 is set between the heating furnace 2 and the descaling machine 3. A heating conveying channel is set in the heating furnace 2, and a heating copper pipe is set in the conveying channel. After the conveying channel is connected to the feeding conveyor 1, multiple raw material workpieces are sequentially conveyed from the feeding conveyor 1 to the conveying channel for heating. The heating principle in the heating furnace 2 is composed of a frequency converter and an induction coil. The frequency converter converts the 50Hz AC power to a medium frequency AC power of 100Hz-10000Hz. The three-phase AC power is rectified into DC power, and then the DC power is converted into an adjustable medium frequency current, which is supplied to the medium frequency alternating current flowing through the capacitor and the induction coil. High-density magnetic lines of force are generated in the induction coil and cut the metal material placed in the induction coil, generating a large eddy current in the metal material. These eddies allow the free electrons of the metal itself to flow in the resistive metal body, generating heat to heat the raw material workpiece; the heating furnace 2 transports the heated raw material workpiece to the descaling machine 3 through the conveyor chain device 21 to remove the oxide scale. A temperature detection device 22 is set between the outlet of the heating furnace 2 and the conveyor chain device 22 to detect the heating temperature of the workpiece. A workpiece filter output port 23 is set on one side of the beginning of the conveyor chain device 22 for outputting workpieces that do not meet the temperature requirements.

[0050] Example 5: Based on Example 4, the workpiece material is first heated in heating furnace 2. The heating process is controlled by the heating control command module 17 of the backend server system 13 via power supply and communication module 215, which controls the heating furnace 2 to heat the raw material. The heating temperature is controlled at 1000℃-1150℃. After heating, the conveying command control module 16 of the backend server system 13, via power supply and communication module 215, conveys the heated workpiece material from heating furnace 22 through heating furnace outlet 20 onto the conveyor chain device 21. The conveying command control module 16 of the backend server system 13 then controls the conveyor chain device 21 via power supply and communication module 25 to input the heated workpiece material into the descaling machine 3 to remove the oxide scale. During oxidation, the oxidation command control module 18 of the backend server system 13, via power supply and communication module 215, controls the descaling machine 3 to remove the oxide scale from the workpiece material. The descaling machine 3 is equipped with a positioning point 43 for fixing the workpiece material. After the workpiece material is oxidized, it is conveyed and placed at the positioning point 43, waiting for the robotic arm 7 to feed it to the hydraulic press for the first overall forging of the workpiece.

[0051] Example 6: Based on Example 5, the working principle of the oxide scale removal machine is as follows: In the oxide scale removal machine system, high-pressure water generated by a high-pressure water pump enters the nozzle of the oxide scale cleaning machine. Under the action of the nozzle, the high-pressure water forms a fan-shaped water jet with a large impact force, which is sprayed onto the surface of the steel billet (or intermediate billet). Under the action of this high-pressure fan-shaped water jet, the iron oxide scale undergoes a process of being cut, rapidly cooled and contracted, peeled off from the base material, and washed away from the surface of the steel billet (or intermediate billet), thereby cleaning the iron oxide scale; when the high-pressure water is sprayed onto the surface of the steel billet through the nozzle, the following changes occur: 1. The fan-shaped surface formed by the water flow is like a sharp blade, cutting open the dense iron scale and forming cracks. Therefore, it can be seen that a thinner fan-shaped surface has a greater impact force; 2. High-pressure water passes through the crack and encounters the high-temperature base material, which rapidly vaporizes and evaporates, creating a destructive effect that peels the iron oxide scale from the base material; 3. After being impacted by water, the iron oxide scale cools and contracts, generating a lateral shear force that peels the iron oxide scale from the base material; 4. The scouring effect of the water jet with a forward tilt angle washes away the already loosened iron scale.

[0052] Example 7: Based on Example 5, please refer to... Figures 4-5 and combined Figure 7 machine Figure 12 In step 4, an integral forging device is installed on the hydraulic press 4. This device includes an upper die changing device 29, a lower die 30, and a push rod 31. At the bottom of the upper die changing device 29, punch 32 and punch 33 are sequentially arranged, spaced a certain distance apart. The push rod 31 is located below the lower die 30. The forging process is as follows: the oxidized workpiece is placed below the lower die 30, and the punch from the upper die changing device 29 is replaced with punch 32 for forging, completing the process as follows. Figure 4 and Figure 7 In the process of integral forging, punch 32 rises to open the die, and the upper die changing device 29 moves punch 33 directly above the lower die 30 to begin stamping, completing the process as follows: Figure 5 and Figure 7 In the second integral forging process, punch 33 rises to open the mold, and ejector pin 31 ejects. During the first and second integral forging processes, the gripping instruction control module 19 controls the robotic arm 7 to grip the oxidized workpiece and place it into the hydraulic press 4 for the first forging. During forging, the electrical control and hydraulic station 6 controls the integral forging device to perform forging through the power supply and communication module 14. During forging, the pressing tonnage is 1500T and the speed is controlled at 100mm / s. After the first and second integral forging processes are completed, rough turning of the outer diameter is performed.

[0053] Example 8, continuing from Example 7, requires cooling after the first overall forging. The backend server's main system's grabbing command control module 19, through power and communication module 2 15, controls the robotic arm 7 to grab the workpiece from the hydraulic press 4 after the first overall forging and place it into the storage tank 5 for cooling. After cooling, the backend server's main system's grabbing command control module 19, through power and communication module 2 15, controls the robotic arm 2 8 to grab the workpiece after the first overall forging and place it into the feeding conveyor 2 9. In this example, please continue to refer to... Figures 1-2 In the middle, the feeding conveyor device 29 is a top material conveyor device, which includes a conveyor belt 24, a container 25 with a top ejection mechanism connected to the conveyor belt 24, and a positioning device 26 connected to the container 25. Multiple conveying stations 27 of the same size are set on the conveyor belt 24. The multiple conveying stations 27 are separated by partition plates 28. Semi-finished workpieces are placed on each conveying station 27. The semi-finished workpieces on each conveying station 27 are conveyed to the container 25 with the top ejection mechanism through the conveyor belt 24.

[0054] Example 9, continuing from Example 7, includes an ejection mechanism and an electric control mechanism at the bottom of the container 25. The electric control mechanism controls the ejection mechanism, which ejects the semi-finished workpiece from the container 25 into the positioning device 26. The positioning device 26 is equipped with a limiting ladder, a second positioning point 44, and an ejection mechanism 2 located at the bottom of the limiting ladder. The electric control mechanism controls the ejection mechanism 1 and the ejection mechanism 2 via a power source. Both the ejection mechanism 1 and the ejection mechanism 2 are hydraulic cylinder driven devices. The hydraulic cylinder driven devices control the height of the limiting ladder. The second positioning point 44 is located on both sides of the end of the limiting ladder. When the semi-finished workpiece is conveyed to the positioning point 44 of the positioning device 26, the robotic arm 28 grabs the workpiece and places it into the heating furnace 2 10 for heating.

[0055] Example 10, based on Example 9, please refer to... Figure 6 In the heating furnace 10, there are three stations: station 1 (40), station 2 (41), and station 3 (42). Semi-finished workpieces are placed at stations 1 (40), 2 (41), and 3 (42) respectively for localized heating according to their size or dimensions. The localized heating temperature is set to 900℃-1000℃. Under the control of the instruction control module 19 in the backend server system 13, the robotic arm 2 (8) places the rough-turned outer diameter workpiece into station 1 (40) of the heating furnace 10 for heating. It then places the workpiece from the forging device 34 into station 2 (42) of the heating furnace 10 for heating, and finally into station 2 of the second heating furnace 10 for heating. Finally, the robotic arm 2 (8) places the workpiece from the forging device 2 into station 3 (43) of the heating furnace 10 for heating.

[0056] Example 11, based on Example 9, please refer to...

The hydraulic press 11 is equipped with a forging device, which includes forging device 1 (34), forging device 2 (35), forging device 3 (36), lower die 1 (37), lower die 2 (38), and lower die 3 (39). Lower die 1 (37) is located below forging device 1 (34), and lower die 2 (38) is located below forging device 2 (35). Below, the lower die 39 is located below the forging device 36. The rough-machined outer diameter is placed into the lower die 37 at the forging device 34 corresponding to the hydraulic press 11 to begin pressing, completing the forging of the first stage. Then, the robotic arm 8 places the forged workpiece into the heating furnace 10 at the corresponding station 42 for heating. After heating, the robotic arm 8 places the forged workpiece into the lower die 38 corresponding to the hydraulic press 11, and the hydraulic press 8 begins pressing to complete the forging of the second stage. Then, the robotic arm 8 places the forged workpiece into the heating furnace 10 at the corresponding station 3 for heating. After heating, the robotic arm 8 places the forged workpiece into the lower die 39 corresponding to the hydraulic press 11 to complete the forging of the third stage. In the forging process, the pressing tonnage is 630T and the speed is 50mm / s. During the heating process, if... Figure 8 As shown, the heating requirement is a head temperature of 1050 degrees Celsius and a tail temperature of 750 degrees Celsius, with the temperature gradually increasing from the tail to the head.

[0057] In Example 12, based on Example 11, in the first and second forging processes, the gripping instruction control module 19 controls the robotic arm 8 to grip the workpiece after the second heating and place it on the hydraulic press 11 for the second forging process via the power supply and communication module 15; during forging, the electrical control and hydraulic station 6 controls the hydraulic press 11 to perform forging via the power supply and communication module 14.
