Description

Tire nitrogen vulcanizing device Technical Field The utility model belongs to the technical field of tire production, and particularly relates to a tire nitrogen vulcanizing device. Background In the production process of the tire, a high-temperature vulcanization process is needed, and the nitrogen vulcanization process has the advantages of energy conservation, high efficiency and the like compared with the traditional vulcanization process, so that the nitrogen vulcanization process is widely applied to the production of the tire. The existing tire nitrogen vulcanizing device generally comprises an upper die, a lower die, a medium path, a heating device and a material taking mechanism, wherein the material taking mechanism is used for taking out a tire from the lower die after vulcanization is completed, the tire is difficult to take out from the lower die by a conventional mechanical claw because the tire is horizontally placed in the lower die, the existing material taking mechanism generally adopts a grapple to hook the inner side edge of the tire, and then the grapple is pulled by a rope to bring the tire out, but in the material taking mode, the tire is easy to shake, the stability of the tire is poor, and the tire is easy to fall. Disclosure of utility model The utility model aims to provide a tire nitrogen vulcanizing device, which solves the problems in the prior art. The utility model provides a tire nitrogen vulcanizing device, which comprises a base, a lower die and a material taking mechanism, wherein the lower die is arranged on the base, the material taking mechanism comprises a U-shaped frame fixedly arranged on the base, a supporting plate slidingly arranged on the U-shaped frame, a lifting assembly for driving the supporting plate to lift, a cylinder fixedly arranged at the bottom of the supporting plate and supporting blocks slidingly arranged around the cylinder; The inside rotation of drum is installed the screw rod, the top fixed mounting of drum has the first motor that is used for driving screw rod pivoted, threaded connection has the slider on the screw rod, all articulate between slider and the four supporting shoe has the bracing piece. As a preferred implementation mode, the lifting assembly comprises a stud rotatably arranged on one side of the U-shaped frame and a second motor for driving the stud to rotate, and one end of the supporting plate is sleeved on the stud and is in threaded connection with the stud. As a preferred embodiment, the second motor is fixedly mounted on the top of the U-shaped frame.
