Abstract

The invention belongs to the technical field of laminated rubber bearing vulcanization methods, and discloses a high-speed vulcanization method of a hysteresis permeation thermal field of a laminated rubber bearing. The high-speed vulcanization method is mainly technically characterized by comprising the following steps: step 1, putting rubber sheets and stiffened steel panels into a mold made of a non-metallic material or a metallic material which does not contain ferrum, cobalt and nickel at intervals; step 2, configuring a high-frequency coil communicated with a high-frequency generator at the outer side of the mold; step 3, starting up the high-frequency generator, providing high-frequency current into the high-frequency coil, generating a rotation magnetic field by the high-frequency coil, and heating the laminated stiffened steel panels uniformly; and step 4, moving an ejection rod of a pressure mechanism at the upper end of the mold upward, turning off the high-frequency generator, taking down the mold, and taking out the bearing. After the high-frequency coil is electrified, the rotation magnetic field is generated and acts on the stiffened steel panels in the rubber bearing, so that the temperature of the stiffened steel panels rises rapidly; each stiffened steel panel heats up rubber at the same time so as to reach the vulcanization temperature rapidly; the heat loss is effectively prevented; the temperature of the working environment of operator is lowered; the stiffened steel panels play a role of improving the intensity of the bearing, and also plays a role of a heat source in processing.
