Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-5 As shown, a frame-type hydraulic vulcanizing machine includes a frame body 1 and a hydraulic station 28. The frame body 1 includes an upper crossbeam 2, a guide device 5, a large gear 6, a small gear 7, an upper heating plate 11, a lifting cylinder 12, a lower heating plate 13, a pressure cylinder 14, a lower crossbeam 16, a robotic arm cylinder 17, a lower platform 18, a linear guide rail 19, a robotic arm 32, an upper support plate 20, a central mechanism 21, a fixed plate 23, a conveying device 26, two side roller frames 27, and a rear inflation device 31. The upper side of the upper crossbeam 2 is equipped with a mold adjustment motor 8, a pin connection 3, a pin bracket 4, a safety cylinder 9, a pin 10, a side plate 15, and a side plate 22. During the production process, the tire vulcanizing machine is fully automatic. All movements and operating procedures are controlled by Mitsubishi's PLC system according to the predetermined values ​​of the tire vulcanizing process and limit switches through a programmable logic controller.

[0022] Furthermore, the upper support plate 20 and the upper heating plate 11 are connected to the mold opening and closing cylinder by a pin through the guide device 5, which facilitates connection control.

[0023] Furthermore, the lifting cylinder 12 pushes the upper support plate 20 and the upper heating plate 11 to move at the upper end of the linear guide rail 19. The lifting cylinder 12 pushes the upper support plate 20 and the upper heating plate 11 to move up and down under the constraint of the linear guide rail 19, which meets the requirements of the mold opening and closing action and can move up and down to realize the mold opening and closing.

[0024] Furthermore, the pressure cylinder 14 drives the lower heating plate 13 to move, and the pressure cylinder 14 pushes the lower platform to move the lower heating plate 13 and the mold upward and pressurize.

[0025] Furthermore, the robotic arm 32 includes a rotating cylinder 34, an adjusting block 33, a fixed plate 23, a gripping cylinder 24, and a connecting rod 25. The gripping cylinder 24 and the connecting rod 25 push the drive plate 29 to rotate along the linear slide rail 30 on the fixed plate 23, facilitating the adjustment of the claw's extension and retraction range. The robotic arm cylinder 17 is connected to the hydraulic station 28 to control the lifting and lowering of the robotic arm 32. The rotation of the robotic arm 32 is controlled by the rotating cylinder. The cylinder stroke is limited by the adjusting block to ensure that the robotic arm 32 rotates to the mold position and stops, and returns to the original position to end, thereby realizing the gripping process.

[0026] Furthermore, the conveying device 26 is located on one side of the two roller conveyor frames 27, and the rear inflation device 31 is located on the other side of the two roller conveyor frames 27.

[0027] Working Principle: A frame-type hydraulic vulcanizing machine operates fully automatically during production. All movements and operating procedures are controlled by a Mitsubishi PLC system according to predetermined values ​​and limit switches in the tire vulcanizing process via a programmable logic controller (PLC). It can vulcanize tires of different types or specifications simultaneously. The tire loading hand device's mechanical gripper picks up the green tire from the green tire tray. The vulcanizing machine opens the mold, the central mechanism's upper ring rises, and the bladder is straightened and vacuumed. The tire loading hand rotates in and descends, placing the green tire on the lower mold's lower steel rim for initial shaping. The tire loading hand then retracts. After rising and rotating out, the vulcanizing machine closes the mold, and the vulcanization cycle begins, proceeding according to the predetermined vulcanization time and procedure. At the end of the vulcanization cycle, the internal pressure is released, the vulcanizing machine opens the mold, and the vulcanizing bladder is extracted from the tire cavity and retracts (upper ring rises). The demolding mechanism lifts the vulcanized tire, lower steel rim, and center mechanism (lower ring rises) from the lower mold. The tire unloading arm swings in and extends horizontally forward to under the tire. After the lower ring returns to its original position, the tire unloading arm, supporting the tire as it rises, retracts backward (at this time, the tire unloading mechanism's tire stop bar is in the rising position). The tire unloading mechanism then flips. The tire unloading mechanism lowers the tire stop bar, and the tire enters the post-inflation device via the connecting roller. After vulcanization completes one cycle, the next cycle begins. This device is easy to operate, with both manual and automatic control functions. It can complete the processes of tire loading, shaping, vulcanization, unloading, post-inflation, and transportation, greatly reducing the labor intensity of workers. It is safe and reliable in operation, capable of automatic operation with safety alarm functions, ensuring long-term stable, accurate, and reliable operation. The advanced control system uses a programmable logic controller (PLC) and data processor as the human-machine interface, capable of storing key process coefficients for three shifts, shift number, time, internal temperature, internal pressure, external temperature, and other status information. The vulcanization process parameters are set, specifications change, and the real-time programming terminal for the vulcanization process uses a touch screen mode and supports Chinese. Before vulcanization, the semi-finished tires are stored in a tire storage tray on the ground. When vulcanization is needed, they are transported to the mold by a robotic arm 32. The specific steps are as follows: the gripping cylinder 24 and connecting rod 25 push the drive plate 29 to rotate along the linear slide rail 30 on the fixed plate 23, which facilitates the adjustment of the claw extension range. The robotic arm cylinder 17 is pressured by the hydraulic station 28 to control the lifting and lowering of the robotic arm 32. The rotation of the vulcanizing machine robotic arm is achieved by the rotating cylinder. The cylinder stroke is determined by the limiting action of the adjusting block to ensure that the robotic arm 32 rotates to the mold position and stops. The return stroke ends when it reaches the original position, thus realizing the gripping process. After vulcanization, the horizontal cylinder drives the left and right tire removal arms to remove the tire from the mold. The swing cylinder extends and retracts to make the tire removal device bracket rotate around the axis. After reaching a certain angle, the tire will slide along the roller by its own weight, ensuring that it moves exactly onto the rear inflation device 31. Adjust the position of the positioning mounting plate and the rubber stop bar to ensure that the tire corresponds to the position of the rear inflation chuck. The cylinder provides power to raise the chuck and lock the tire, realizing the rear inflation of the tire. After inflation, the swing cylinder extends and retracts, causing the rear inflation device 31 to rotate around the rear inflation swing shaft. The inflated tire slides into the conveyor device 26 by its own weight through the movable roller frame.
