Description
Technical field
The present invention relates to tire production technology and apparatus field, at length say it is a kind of tyre cavity electromagnetism baking device.
Background technology
As everyone knows, temperature is one of tyre vulcanization essential condition, therefore sulfuration becomes the main power consumption operation in the tire production process, the steam consumption of factory 80% all is dropped in this operation, but these steam reality are absorbed seldom by tire, great majority consume in the middle of invalid pipeline circulation, and energy waste is serious.
In present institute extensively in the nitrogen sulfuration process of employing, saturated vapor is after entering capsule, because the low part of capsule internal surface temperature forms the condensed water savings in the capsule bottom, make the capsule upper and lower sides temperature difference bigger, thereby cause on the tire base lower sidewall state of cure (vulcanization) inconsistent, the quality of tire descends, though each tire plant adopts repeatedly measures such as condensate drain and improvement inlet structure that the capsule upper and lower sides temperature difference is to a certain degree dwindled, this defective workmanship can't be solved all the time at all.
Summary of the invention
The objective of the invention is to the deficiency at existing tyre vulcanizing, provide a kind of heat transfer efficiency height, energy consumption low, and can solve at all and go up tyre cavity electromagnetism baking method and the device that there is this drawback of the temperature difference in the lower sidewall in the sulfidation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tyre cavity electromagnetism baking device, be provided with telescopic metal inner mold, inner mold is by polylith drum watt and be connected with it and passive gusset is formed, can under the driving of central authority piston rod, realize radially breathing for bulging watt, it is characterized in that, the every drum watt back side is equipped with an electromagnetic heater, electromagnetic heater is made up of two identical heating units of structure, heating unit comprises solenoid, magnetic core, thermal insulation layer, shell, solenoid is wrapped on the magnetic core, coil surface is coated with thermal insulation layer, the 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 piece drum watt back mounted two groups of solenoid is identical, solenoid is symmetrically distributed in the left and right sides of bulging watt longitudinal centre line, and direction of winding along bulging watt vertically.
The present invention also can realize by following measure: heating unit and gusset are fixing by the silica gel bonding.Be wrapped in two solenoids on the heating unit magnetic core and be in series by a long lead, and the winding direction of two groups of coils is identical.Thermocouple is equipped with in a drum watt inside center position, so that a drum watt surface temperature is monitored in real time.Gusset and shell are made by non-magnetic metal material.Magnetic core is made by having the magnetic conduction materials with function.Made by the metal material with magnetic conductivity for bulging watt.
The invention has the beneficial effects as follows, when being heated, tire base inner chamber need not to consume dynamic mediums such as steam, superheated water, but employing way of electromagnetic induction, the heat transfer efficiency height, curing cycle is short, saved the energy greatly, and the inconsistent problem of state of cure (vulcanization) is deposited in the lower sidewall on can solving in the conventional tire sulfuration process at all.
