Axle head wear
Due to the metal material and high hardness of the vulcanizing machine, it is subject to vibration and impact as well as other complex forces during production, leading to gaps in the components and causing wear. Traditional repair methods include surfacing, thermal spraying, and electroplating, but each method has its drawbacks: surfacing can cause the surface of the parts to reach very high temperatures, resulting in deformation or cracking, affecting dimensional accuracy and normal use, and in severe cases, even leading to fracture; electroplating, while not having thermal effects, cannot have a thick coating, causing severe contamination and limiting its application.
Western countries often employ the method of high polymer composite materials to address these issues. Their comprehensive properties and the ability to be mechanically processed at any time meet the requirements for use and precision after repair, while also reducing the impact and vibration the equipment endures during operation, thereby extending its service life. As the material has a "variable" relationship, when subjected to external force, it deforms to absorb the force and expands or contracts with the bearing or other components, maintaining a tight fit with the parts and reducing the likelihood of wear. For the wear on large vulcanizing machines, on-site repairs can also be performed using "molds" or "matching components" to address damaged equipment, avoiding the need for complete disassembly of the equipment, ensuring the mating dimensions of the parts, and meeting the production and operation requirements of the equipment.
Weld Seam Leak
During the long-term operation of vulcanizing machines, oil leakage at the static seal areas of various interfaces is quite common due to factors such as vibration, wear, pressure, temperature, and repeated disassembly and assembly. Common issues include渗漏 in the hot plate welds of vulcanizing machines. This not only leads to significant waste of oil but also affects the on-site management of enterprises. Traditional remedial methods require disassembling and opening the vulcanizing machine to replace seal gaskets or apply sealant, which is time-consuming and labor-intensive. Moreover, it is difficult to ensure effective sealing, and leaks may reoccur during operation.
III. Substrate Corrosion
The base plates of vulcanizing machines are typically made of ordinary carbon steel. Tyres are vulcanized using high-temperature steam, during which condensation of some water permeates through the surface of the base plate, causing localized corrosion and an uneven surface. Due to severe surface corrosion, the base plate cannot ensure a tight fit with the insulating plate surface, making it prone to damage under high pressure. Traditional methods mainly involve re-welding and re-machining, or replacing new equipment. Currently, on-site repairs can be made using high polymer composite materials. With its adhesive properties, excellent corrosion resistance, and good compressive strength, this material can effectively address the issue of condensation water causing corrosion and unevenness on the base plate during operation, thereby preventing the destruction of the insulating plate. This provides a good guarantee for the normal operation and safe production of the user's equipment.
