[0024] Working Principle: This hydraulic tire vulcanizing machine can be used to vulcanize wide-section, high-grade radial tires. The green tire undergoes automatic loading, shaping, vulcanization, and unloading processes on the machine. Under heating and pressure, the tire is vulcanized and formed. The operator places the tire holder containing the green tire in the tire-grabbing position of the loading robot 12. The loading robot 12 receives information from the PLC to grab the green tire. The mechanical claw of the loading robot 12 descends, the tire contactor touches the green tire, the mechanical claw opens and grabs the green tire, and the loading robot 12 rises to the upper position, then rotates to the loading position. The tire is lowered to the loading height, and the green tire is rotated onto the lower steel ring in the lower mold. The upper ring retracts, and the vulcanizing bladder extends into the green tire. First-stage setting steam is introduced to fix the green tire onto the lower steel ring. When the first-stage setting steam reaches the predetermined pressure value, the loading robot 12's grippers retract and move upwards, rising to the highest position and then rotating out above the tire gripping position. After the loading robot 12 rotates out, the safety pin retracts, and the vulcanizing machine begins to close the mold. The movable mold opens, the upper mold presses down on the upper ring, and the vulcanizing machine continues to close the mold. The movable mold drive cylinder's rodless chamber and the upper ring rise... The rodless chamber of the lowering cylinder overflows, the rod chamber of the movable mold drive cylinder and the rod chamber of the upper ring lifting cylinder replenish oil, the upper mold continues to press down to the mold closing end point, the vulcanizing machine closes the mold to the end point and reaches the predetermined mold closing force, the tire begins vulcanization, the tire loading robot grabs the tire position, lowers and grabs the green tire, and then rises to the highest position, the vulcanization cycle ends and the internal pressure is released, the vulcanizing machine opens the mold to the limit, when the mold opens, the movable mold side opens, the lower ring rises to the upper limit, the tire unloading robot 21 moves from the highest position of the tire unloading position to the tire picking position, the tire unloading robot lowers to the tire picking height and opens, the upper As the ring rises to its limit and the lower ring descends to its limit, the tire unloading robot 21 rises to its highest position. The connecting roller swing frame swings upward, and the tire unloading robot 21 rotates from the highest position of the tire pick-up position to the tire unloading position and descends to the tire unloading height. The tire unloading claw closes, and the tire is unloaded onto the connecting roller swing frame. The tire loading robot rotates in and descends, rotating the green tire onto the lower steel rim. The connecting roller swing frame swings downward, and the tire is transported to the connecting roller frame. The central mechanism 8 is used to manipulate the capsule and serves as part of the channel for the vulcanizing medium (i.e., internal pressure, including steam and nitrogen) and condensate inside the capsule.It allows the upper end of the capsule to be fixed to the upper ring of the central mechanism using a clamp (upper ring), while the lower end of the capsule is fixed to the central cylinder thread (lower ring) of the central mechanism using a clamp. Driven by the upper ring lifting cylinder, the upper clamp of the capsule can extend and retract vertically. Simultaneously, under the action of the lower ring lifting cylinder, the lower ring, along with the lower steel ring, moves up and down. When the green tire is placed on the lower steel ring of the central mechanism, this mechanism can cooperate with the main machine to complete a series of operations, including shaping, vulcanization, and after vulcanization, removing the tire from the lower mold, pulling out the capsule, and finally separating it from the tire bead. This mechanism ensures that the various media are sprayed evenly into the inner wall of the capsule in a rotating and radial state, resulting in uniform temperature of the inner wall of the capsule to ensure the quality of the product. The upper ring on the upper ring of this mechanism has a maximum extension... With a linear stroke of 850 mm, it can meet the requirements of various bladder extension heights for vulcanized tire specifications specified by the machine. The extension height adjustment for different tire specifications can be achieved through a displacement sensor at the lower center of the upper ring lifting cylinder, changing the bladder extension height setting value on the touchscreen to meet the requirements of different tire specifications. The tire loading robot 12 is installed on the front left and right sides of the frame 1. Its function is to automatically extract the green tire from the tire holder and send it into the vulcanizing mold (lower mold), playing an auxiliary positioning role during tire pre-forming. There are two sets of tire loading robots: a left tire loading robot and a right tire loading robot. The left and right grippers are connected to the lifting frame and move up and down along the linear guide rail under the drive of the lifting cylinder. The left and right grippers respectively grab the green tire from the tire picking position and send it into the center of the mold (lower mold), playing an auxiliary positioning and guiding role during tire pre-forming.The rotating arm, tire gripper, and rotating shaft are driven by a rotary cylinder. Under the control of limit switches and the action of limit adjustment screws, they can stop at two positions (tire loading position and tire removal position). The buffer can effectively buffer the impact caused by speed changes during the rotation process. The different tire loading and tire removal heights of the tire gripper are controlled by displacement sensors. The tire gripper is driven by a tensioning cylinder to realize the opening and closing movement of the gripper. The tire unloading robot 21 is installed in the middle of the rear side of the frame 1. Its function is to automatically grab the vulcanized tire from the tire removal position (mold center), rotate it to the tire unloading position, and place the tire on the connecting roller conveyor. There are two sets of tire unloading robots, namely the left tire unloading robot and the right tire unloading robot. The left and right tire unloading claws are connected to the lifting frame and move up and down along the linear guide under the drive of the lifting cylinder. When the vulcanization cycle is completed, the tire and the lower steel rim, together with the central mechanism ring seat, are lifted by the lower ring lifting cylinder, and the tire is disengaged from the lower mold. The left and right tire unloading claws move from the tire removal position to the tire removal position. The vulcanized tire is gripped at the model center, raised to the upper limit, and rotated to the tire removal position. The tire is placed on the connecting roller conveyor. The rotating arm, tire removal claw, and rotating shaft are driven simultaneously by the rotary cylinder (rear) and the rotary cylinder (front). Under the control of the limit switch and the action of the limit adjustment screw, it can stop in two positions (tire loading position and tire removal position). The buffer can effectively buffer the impact caused by speed changes during the rotation process. The different tire removal height and tire removal height of the tire removal claw are controlled by the height position of the manual adjustment proximity switch. The tire removal claw is driven by the opening and closing cylinder to realize the opening and closing movement of the claw. The rear inflation device 23 adopts a two-station four-point structure, which can simultaneously inflate, cool, and shape four tires. When the tire is vulcanized, in order to keep the tire in the correct size, it should be sent into the rear inflation device 23 in time so that the tire can be fully cooled and shaped while inflated. The power distribution cabinet 4 includes all electrical control components and PLC system for easy control.
