Description
Technical field
The present invention relates to tire production technology and apparatus field, is a kind of tyre cavity Electromagnetic Heating vulcanization plant in detail.
Background technology
As everyone knows, temperature is one of tyre vulcanization essential condition, therefore sulfuration becomes the main power consumption operation in tire production process, the steam consumption of factory 80% is all dropped in this operation, but these steam actual by tire absorb little, great majority consume in the middle of the circulation of invalid pipeline, and energy waste is serious.
In the nitrogen sulfuration process extensively adopted at present, saturated vapor is after entering capsule, because capsule internal surface temperature is low, part forms condensed water savings at capsule bottom, make the capsule upper and lower sides temperature difference larger, thus cause lower sidewall state of cure (vulcanization) on tire base inconsistent, the Quality Down of tire, reduce to a certain extent although each tire plant adopts repeatedly the measure such as condensate drain and improvement inlet structure to make the capsule upper and lower sides temperature difference obtain, this defective workmanship cannot be solved all the time at all.
Summary of the invention
The object of the invention is to the deficiency for existing tyre vulcanizing, provide that a kind of heat transfer efficiency is high, energy consumption is low, and upper lower sidewall in sulfidation can be solved at all there is tyre cavity Electromagnetic Heating vulcanization process and the device of this drawback of the temperature difference.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tyre cavity Electromagnetic Heating vulcanization plant, be provided with telescopic metal inner mould tool, inner mold is by polylith drum watt and be connected with it and passive gusset forms, drum watt can realize radial breathing under the driving of central authority piston rod, it is characterized in that, every block drum watt back side is provided with an electromagnetic heater, electromagnetic heater is made up of two heating units that structure is identical, heating unit comprises solenoid, magnetic core, thermal insulation layer, shell, solenoid is wrapped on magnetic core, coil surface is coated with thermal insulation layer, heating unit outermost layer is shell, two heating units are symmetrically distributed in the left and right sides of gusset center line in parallel to each other, the inductance value of each block drum watt back mounted two groups of solenoids is identical, solenoid is symmetrically distributed in the left and right sides of drum watt longitudinal centre line, direction of winding is along drum watt longitudinal direction.
The present invention also realizes by following measure: heating unit and gusset are fixed by silicone adhesive.The solenoid be wrapped on two heating unit magnetic cores is in series by a long lead, and the winding direction of two groups of coils is identical.A drum watt inner hub location is equipped with thermocouple, to monitor in real time a drum watt surface temperature.Gusset and shell are made up of non-magnetic metal material.Magnetic core is made up of the material with magnetic conduction function.Drum watt is made up of the metal material with magnetic conductivity.
The invention has the beneficial effects as follows, when heating tire base inner chamber without the need to consuming the dynamic medium such as steam, superheated water, but employing way of electromagnetic induction, heat transfer efficiency is high, curing cycle is short, greatly save the energy, and lower sidewall can be solved in conventional tire sulfuration process at all deposited the inconsistent problem of state of cure (vulcanization).
