[0002] Currently, the stability of the hydraulic system in rubber vulcanizers is crucial to the overall operation of the machine. The connection between the cylinder and piston in this hydraulic system is particularly crucial. Both the piston and cylinder are major components in the vulcanizer, responsible for transmitting pressure. Oil seals are subject to high pressure, rapid wear, severe aging, and harsh operating environments, making them the primary vulnerable parts of the vulcanizer cylinder.

[0003] In the existing technology, the clamping force cylinder body and the connecting cover of the on-site monomer vulcanizer are fixed with 24 bolts. The bolts have been in service for a long time, and some bolts are corroded and broken. There is a risk of the clamping force cylinder falling. The falling of the clamping force cylinder will cause the clamping force pressure to drop, and the process technology of the finished tire cannot be met. The finished tire will have large rubber edges, resulting in waste and defective products.

[0004] Based on this, the existing technology needs to be further improved. Utility Model Content

[0009] Furthermore, the first reinforcement assembly includes a first bolt, and a connecting seat is provided at one end of the cylinder body close to the connecting cover, and one end of the first bolt is threadedly connected to the connecting seat and the connecting cover respectively.

[0010] Furthermore, the first bolt is a stud bolt, and the other end of the first bolt is threadedly connected to the connecting seat and the second reinforcement component to achieve the connection between the cylinder body and the support plate.

[0011] Furthermore, the second reinforcement assembly includes a second bolt and a nut sleeve, the nut sleeve is threadedly connected to the end of the first bolt, and the second bolt passes through one end of the support plate and is threadedly connected to the nut sleeve.

[0012] Furthermore, a flat washer and a spring washer are provided between the nut sleeve and the connecting seat. The flat washer is arranged in contact with the surface of the connecting seat, and the spring washer is located between the flat washer and the nut sleeve.

[0013] Furthermore, the second bolt is a stud bolt, and one end of the second bolt away from the connecting seat is threadedly connected to the support plate and the locking nut, and a flat washer and a spring washer are provided between the locking nut and the support plate.

[0014] Furthermore, the reinforcement components are provided in a plurality of groups, and the plurality of groups of reinforcement components are distributed in an array along the circumferential direction of the cylinder body, so that the support plate is subjected to uniform force and the reinforcement effect is enhanced.
