Electromagnetic sulfuration system

Abstract

The invention provides an electromagnetic sulfuration system. A sulfuration mold is improved; a magnetic conduction tank made of magnetic conduction ceramic materials for accommodating an electrifyingcoil is arranged inside the sulfuration mold; the electrifying coil is electrically connected with an external medium-high frequency power supply, so that medium-high frequency current is obtained; afirst magnetic field is generated for heating a steel plate; the electrifying coil is directly arranged inside the sulfuration mold; the magnetic field generated by the electrifying coil is restrained inside the sulfuration mold through the magnetic conduction ceramic materials; the condition that an alternating magnetic field generated by the electrifying coil acts on the mold body can be avoided, so that the alternating magnetic field can be totally used for heating the steel plate. An upper heating plate and a lower heating plate of a sulfuration machine can be fast heated through heat conduction oil; further, heat is fast conducted to an upper mold and a lower mold of the sulfuration mold. Therefore the temperature of the upper mold, a middle mold and the lower mold of the sulfurationmold can be fast and uniformly raised; the temperature of the steel plate at inside is fast and uniformly heated, so that the sulfuration efficiency and the sulfuration quality of a rubber support seat are improved.

Description

technical field [0001] The invention belongs to the technical field of vulcanization of rubber bearings, and in particular relates to an electromagnetic vulcanization system. Background technique [0002] At present, the production of rubber bearings uses a flat vulcanizer to vulcanize the rubber bearings. The specific process is: place the mold with the upper mold, middle mold and lower mold between the upper heating plate and the lower heating plate of the vulcanizing machine, and the rubber The support is placed inside the mold, and the rubber support is laminated with rubber and steel plates at intervals, and the steel plate is between two adjacent layers of rubber. When heating, heat the heat-conducting oil with a boiler, and then transfer the heat-conducting oil to the flat vulcanizing machine with a pipeline, and heat the upper heating plate and the lower heating plate of the flat vulcanizing machine by means of heat conduction. Then use the upper heating plate and t...

Problems solved by technology

[0003] (1) Since rubber is a poor conductor of heat, in order to ensure the vulcanization quality of rubber bearings, the vulcanization time of rubber bearings must be extended, resulting in a long processing and vulcanization time

[0004] (2) Since rubber is a poor conductor of heat, in the process of heat conduction, the place close to the upper mold and the lower mold is heated first, and the heating time is longer, and the temperature at the center of the support is higher, resulting in uneven vulcanization of the support, especially For the large-area support and the support with a high height, the place close to the upper mold and the lower mold has been vulcanized, but the place far away from the upper mold and the lower mold has not been vulcanized, resulting in insufficient vulcanization of the rubber and the rubber part of the support. The lining steel plate is detached, and the service life is low

After actual tests, the inventor found that the effect of this heating method is not ideal, because the mold itself is made of metal materials, which have a strong shielding effect on electromagnetic fields, and the alternating electromagnetic field generated by the energized coil outside the mold is almost all It acts on the mold itself and cannot enter the interior of the mold, let alone heat the rubber support inside the mold.

Therefore, the electromagnetic heating method in the prior art is not feasible
