Description

Technical Field

Furthermore, this invention also relates to equipment comprising the aforementioned multi-station cylinder liner casting and transfer system. Background Technology

[0002] Pneumatic actuators with long strokes and a large proportion of cylinder (tube) are generally called long-tube cylinders. Their core is still a regular cylinder: it consists of a cylinder, piston, piston rod, end cap and seals, and is driven by compressed air to make reciprocating linear motion.

[0003] In existing centrifugal casting processes using roller-type long cylinder liner blanks, there are few workstations. While core processes such as molten iron pouring are mechanically operated, steps like workstation switching, mold loading and unloading, and troubleshooting rely on manual assistance, resulting in low production efficiency. Furthermore, the presence of cooling processes such as quenching creates a humid environment, leading to a high equipment failure rate. Each workstation requires manual monitoring and coordination, resulting in a low level of production automation.

Detailed Implementation

[0041] 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.

[0042] The core of this invention is to provide a multi-station cylinder liner casting and transfer system, which can improve the automation level of the cylinder liner production process and thus improve production efficiency.

[0043] Another core aspect of this invention is to provide an apparatus that includes the aforementioned multi-station cylinder liner casting and transfer system.

[0044] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] This application provides a multi-station cylinder liner casting and transfer system, comprising: a substrate 1, a casting assembly, a stepping assembly 2, a cylinder removal assembly, a cleaning assembly, and a spraying assembly;

[0046] The substrate 1 is equipped with several production stations, including a centrifugal casting station, a cylinder removal station, a cooling station, a cleaning station, a spraying station, and a drying station. The production stations are used to store several molds.

[0047] The casting assembly is located on the base 1 and is used for casting into the mold;

[0048] Stepper assembly 2 is located on base 1 and is used to drive the mold to move between several production stations;

[0049] The cylinder removal assembly is located at the cylinder removal station and is used for mold demolding;

[0050] The cleaning unit is located at the cleaning station and is used to clean the mold;

[0051] The spraying assembly is located at the spraying station and is used to spray the mold.

[0052] For details, please refer to the appendix. Figure 1 With appendix Figure 2 The base 1 is a frame assembly, in which a centrifugal casting station, a cylinder removal station, a cooling station, a cleaning station, a spraying station, and a drying station are arranged sequentially. A casting assembly is provided at the casting station to cast into the mold. A cylinder removal assembly is located at the cylinder removal station to demold the mold. A cleaning assembly is located at the cleaning station to clean the mold. A spraying assembly is located at the spraying station to spray material onto the mold. The mold performs the corresponding steps when it arrives at each station. The movement of the mold is achieved by a stepping assembly 2. The whole process is highly automated, reduces manual intervention, and improves production efficiency.

[0053] In addition, please refer to the appendix. Figure 3Taking this as an example, as an embodiment of this application, there are a total of ten stations from left to right. The first to third stations are centrifugal casting stations, where molten iron is poured sequentially and centrifugally rotated during production. The fourth station is the mold removal station, used to remove the blank from the mold. The fifth station is the mold cooling station, used to store and cool the mold. The sixth station is the mold cleaning station, used to clean the coating inside the mold hole. The seventh station is the air blowing station, used to blow away the residual coating inside the hole. The eighth station is the spraying station, used to spray the coating onto the mold. The ninth station is the drying station, used to store and dry the mold. The tenth station is the standby station. The standby station can be understood as a backup station, which can be used to deal with emergencies. When it is necessary to replace the mold currently in use on the equipment, the standby station can be put into use, and the original mold can be moved to the loading ramp and unloaded by a forklift.

[0054] It should be noted that there is a time difference between the first three pouring stations. Each centrifugal pouring has a certain rotation and shaping time, but the start time and end time are different. The first three stations are independently transported to station number four. The process pace of the fourth to ninth stations is faster. The number of pouring stations can be calculated based on the time difference.

[0055] Additionally, you can refer to Figure 13 The process flow diagram of this application is as follows: First, the mold is loaded with material, and then it is transported by the transport component so that the mold enters the first to third casting stations in sequence for casting. Then, the transport component transports the molds at the casting stations to the cylinder removal station in sequence. The molds at the fourth to eighth stations are stepped to the next station by the stepping beam 4. For example, the mold at the fourth station is stepped to the fifth station. Then, the transport component transports the mold at the ninth station to the centrifugal casting station. This cycle is repeated for production.

[0056] Based on the above embodiments, the stepping assembly 2 includes a servo electric cylinder 3, a stepping beam 4, a first connecting rod 5, a second connecting rod 6, and a hydraulic cylinder 8. The output end of the servo electric cylinder 3 is connected to the stepping beam 4. The stepping beam 4 is connected to the base 1 through the first connecting rod 5. The output end of the hydraulic cylinder 8 is connected to the second connecting rod 6. The second connecting rod 6 and the first connecting rod 5 are connected through a rotating shaft.

[0057] For details, please refer to the appendix. Figure 5 With appendix Figure 6The servo electric cylinder 3 and hydraulic cylinder 8 of the stepping component 2 are both fixed to the base 1. The output end of the servo electric cylinder 3 is connected to the stepping beam 4. The stepping beam 4 has a ring-shaped frame structure, which can be rectangular or other shapes, depending on the actual situation. The stepping beam 4 is rotatably connected to the base 1 through the first connecting rod 5. The hydraulic cylinder 8 is connected to the rotating shaft through the second connecting rod 6. The rotating shaft is connected to the first connecting rod 5. During operation, the output end of the hydraulic cylinder 8 extends to drive the second connecting rod 6 and the first connecting rod 5 to rotate, thereby driving the stepping beam 4 to rise. After the stepping beam 4 is raised, the servo electric cylinder 3 works, and its output end extends to drive the stepping beam 4 to move horizontally, transporting the mold to the next work station. Then, the hydraulic cylinder 8 drives the stepping beam 4 to fall, and the servo electric cylinder 3 drives the stepping beam 4 to move horizontally and reset.

[0058] Based on the above embodiments, the stepping assembly 2 also includes a third link 7 and a synchronizing rod 9. There are four first links 5, and two each of the rotating shaft, second links 6, third links 7 and hydraulic cylinders 8. The first links 5 are located at the four corners of the stepping beam 4. The output ends of the two hydraulic cylinders 8 are respectively connected to the two second links 6. The third links 7 rotate synchronously with the second links 6 through the rotating shaft. The two third links 7 are connected through the synchronizing rod 9.

[0059] Specifically, a third connecting rod 7 and a synchronizing rod 9 are also provided on the base 1. The third connecting rod 7 is fixedly connected to the rotating shaft, and the two third connecting rods 7 are rotatably connected through the synchronizing rod 9. There are two corresponding rotating shafts and two oil cylinders 8. When one of the oil cylinders 8 outputs, it can drive the third connecting rod 7 to rotate. The third connecting rod 7 can drive the other third connecting rod 7 to rotate through the synchronizing rod 9, that is, the other rotating shaft rotates at the same amplitude. In this way, it can be ensured that the rotation amplitude of the four first connecting rods 5 is the same, that is, to ensure that the stepping beam 4 is always in a horizontal state, and to ensure the precise position movement of the mold.

[0060] Based on the above embodiments, the stepping component 2 also includes a first V-groove 10 and a roller groove 11. Both the first V-groove 10 and the roller groove 11 are provided in multiple quantities and are distributed at both ends of the stepping beam 4.

[0061] Specifically, the stepping beam 4 is also provided with a first V-groove 10 and a roller groove 11. It should be noted that the first V-groove 10 and the roller groove 11 should be provided in pairs to position and support the two ends of the mold. The structure of the first V-groove 10 and the roller groove 11 can be found in the attached diagram. Figure 5 With appendix Figure 6 .

[0062] Based on the above embodiments, the centrifugal casting station is also provided with a motor 12 and a roller shaft assembly 13. Multiple motors 12 and roller shaft assemblies 13 are provided. The motors 12 and roller shaft assemblies 13 are connected to drive the roller shaft assembly 13 to rotate. The roller shaft assembly 13 is used to drive the mold to rotate centrifugally.

[0063] For details, please refer to the appendix. Figure 4 Multiple motors 12 and roller shaft assemblies 13 are provided. Multiple motors 12 are arranged at intervals and connected to roller shaft assemblies 13 one by one. The motors 12 provide power for the rotation of roller shaft assemblies 13, and drive the mold to rotate through roller shaft assemblies 13.

[0064] Based on the above embodiments, the roller shaft assembly 13 includes a first spacer 14, a second spacer 15, an air blowing port 16, a first roller 17, a second roller 18, a first tightening sleeve 19, a second tightening sleeve 20, and a roller shaft. The first roller 17 and the second roller 18 are respectively disposed at both ends of the roller shaft. The first tightening sleeve 19 and the second tightening sleeve 20 are respectively disposed on the first roller 17 and the second roller 18. The first spacer 14 is sleeved on the outer periphery of the second spacer 15, and the second spacer 15 is sleeved on the roller shaft.

[0065] For details, please refer to the appendix. Figure 11 With appendix Figure 12 The diameters at both ends of the support roller shaft are smaller than the diameter of the middle section. A first support roller 17 and a second support roller 18 are respectively provided at both ends of the support roller shaft. A first expansion sleeve 19 is provided between the first support roller 17 and the support roller shaft, and a second expansion sleeve 20 is provided between the second support roller 18 and the support roller shaft. When the mold is overloaded, slippage can be achieved, avoiding equipment failure caused by motor overload and reducing the failure rate. An air blowing interface 16 is provided on the surface of the bearing, which is connected to the air supply component of the workshop. A first spacer 14 and a second spacer 15 are also provided between the bearing and the support roller shaft. The first spacer 14 and the second spacer 15 can form a labyrinth-like slot. The air supply component can vent air to the bearing through the air blowing interface 16. More specifically, dry compressed air can be blown into the slot to prevent water vapor from entering the bearing, thereby preventing water from entering the bearing when water is splashed.

[0066] Based on the above embodiments, a transport assembly is also provided on the base 1. The transport assembly includes a transport gripper 21 and a lifting and walking assembly 22. The lifting and walking assembly 22 is connected to the transport gripper 21 and is used to drive the transport gripper 21 to move.

[0067] Specifically, the structure of the transport component can be found in the attached document. Figure 7 With appendix Figure 8 Its main function is to transport the mold after the paint has dried to the centrifugal casting station and to transport the cast mold to the cylinder removal station. Its structure mainly includes a transport gripper 21 and a lifting and walking assembly 22. The lifting and walking assembly 22 is used to drive the transport gripper 21 from one designated position to another.

[0068] Optionally, the lifting and walking assembly 22 can use a combination structure of control system and electric cylinder, which is relatively common and low cost.

[0069] Based on the above embodiment, the transport gripper 21 includes a second V-groove 23, a hinge 24 and a touch switch 25. The hinge 24 is connected to the second V-groove 23 and is used to drive the second V-groove 23 to rotate.

[0070] Specifically, the structure of the handling gripper 21 can be found in the attached diagram. Figure 9 With appendix Figure 10 The overall structure of the transport gripper 21 can be regarded as a U-shaped structure. A second V-groove 23 and a hinge 24 are provided at its lower end. The hinge 24 is used to rotate the arm when there is a positional error when it reaches the top of the mold, so as to prevent collision failure. The touch switch 25 is used to sense the mold position signal and transmit the relevant signal to the lifting and walking component 22 to adjust the working state of the lifting and walking component 22.

[0071] Based on the above embodiments, the transport assembly also includes a water spraying assembly 26 and a temperature measuring assembly 27 connected by signals. The temperature measuring assembly is used to measure the temperature of the mold, and the water spraying assembly 26 is used to spray water onto the mold for cooling.

[0072] Specifically, at the cylinder removal station, after the blank is removed, the temperature measuring component 27 first measures the mold temperature, then feeds back the temperature to the water-cooling component 26 in the form of an electrical signal, and sets the water-cooling time. Water is then sprayed onto the mold through the water-cooling component 26 to achieve mold cooling.

[0073] In addition to the multi-station cylinder liner casting and transfer system described above, the present invention also provides an apparatus including the multi-station cylinder liner casting and transfer system disclosed in the above embodiments.
