Technical field
The utility model relates to a kind of electric heater unit, specifically a kind of dismounting mould electric heater unit of exempting from.
Background technology
We know, forge will carry out mould and die preheating before forging production, in forging production,, also must be preheating to more than 300 ℃ so that just can enter production after increasing its toughness, raising intensity mold tooling because breakdown maintenance causes mold temperature to cross when hanging down.Present domestic forging producer generally adopts the mode heating mould of naked light (combustion medium is natural gas, heavy oil, diesel oil, kerosene etc.).There are following problems in this mode of heating: (1) is seriously polluted: because a large amount of oil smoke of the insufficient generation of burning causes serious pollution to environment; (2) wasting of resources:, cause a large amount of energy wastes because that the burn incompletely of combustion medium is added naked light heating heat dissipation is more; (3) mold heated is inhomogeneous: adopting the mode of heating of naked light is mould and die preheating, and firing rate surpasses heat conduction velocity, causes in the mould table temperature to differ big easily and each position of mould is heated inhomogeneously, greatly reduces useful life of mould; (4) have potential safety hazard, diesel oil belongs to inflammable explosive article, operates lack of standardizationly, causes blast and potential safety hazard such as fire easily.
And forge's mold weight have reach several tons of weights, volume is big, needs auxiliary equipment to finish dismounting, adopts 20 tons of cranes and 1.5 tons of percussion hammers bump mould drift modes to dismantle mould at present, changes the heating of mold heated stove then over to.Also there are a lot of drawbacks in this dismounting mode: utilize crane to hang percussion hammer bump drift dismounting mould, threaten operator's life security easily and equipment is caused damage; Carry out the dismounting of mold tooling for a long time, very easily the corresponding connecting portion of equipment is caused excessive wear, produce fault, when increasing the equipment downtime platform; The repetition dismounting of mold tooling causes the duplication of labour, has increased workman's the amount of labour, reduces production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, easy to use, efficiency of heating surface height, and safety and environmental protection, labour intensity is low exempts from dismounting mould electric heater unit.
The technical scheme in the invention for solving the above technical problem is: a kind of dismounting mould electric heater unit of exempting from, it is characterized in that: it comprises a hollow outer cover, hollow outer cover wall installed inside is fixed with heat-insulation layer, be provided with six layers of porcelain tube in the heat-insulation layer equably, be wound with resistance wire on the porcelain tube, resistance wire is powered by three phase mains.
The utility model also is provided with a thermocouple, and thermocouple is inserted in heat-insulation layer inboard in the hollow outer cover.Temperature when being used for measuring inner mold heating of monitoring hollow outer cover and insulation.
The said hollow outer cover of the utility model is the hollow stainless steel outer cover of the no end that is cuboid, and its outside is symmetrically installed with four trapezes.Be used for lifting whole device by driving and trapeze cooperation, convenient moving.Lifting hollow outer cover will heated mold cover during work, with regard to not needing mould is carried out dismounting like this, realizes that the dismounting of exempting from of mould is heated.
The said heat-insulation layer of the utility model is the alumina silicate fiber felt heat-insulation layer, and it evenly adheres to and is fixed on hollow outer cover wall inboard.Play good insulation effect, the mould in the hollow outer cover can be incubated in the scope of design temperature.
The said resistance wire of the utility model is pressed against aluminium alloy resistance silk for helical form iron, and it is wrapped in respectively on six layers of porcelain tube equably, and resistance wire is divided into three groups, and whenever two-layer is one group, and each group is a phase, is powered with wye connection by three phase mains.An end that is three-phase links to each other, and the other end is received respectively on the 380V three phase mains.Porcelain tube plays a part to support resistance wire, and helical form iron is pressed against aluminium alloy resistance silk and produce heat after energized, is mold heated.
The utility model adopts the hollow outer cover that can lift that mould is carried out electric heating, and against existing technologies, the utility model is rational in infrastructure, and is easy to use, efficiency of heating surface height, and safety and environmental protection, labour intensity is low.This device is installed in to be needed on the heated mold, and energized can be used, and after mould and die preheating was finished, deenergization unloaded this device and gets final product, and that has realized mould exempts from the dismounting heating, is suitable for various mold heated.Be specially adapted to forge preheating of production front mold and production line and mould heated usefulness because breakdown maintenance causes mold temperature to cross and hangs down.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is that the utility model is formed structural representation.
Fig. 2 is that the utility model is overlooked the partial cutaway diagrammatic sketch.
Number in the figure is: 1. hollow outer cover, 2. heat-insulation layer, 3. resistance wire, 4. porcelain tube, 5. three phase mains, 6. thermocouple, 7. trapeze.
Embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of dismounting mould electric heater unit of exempting from, it comprises a hollow outer cover 1, hollow outer cover 1 wall installed inside is fixed with heat-insulation layer 2, install equably in the heat-insulation layer 2 and be provided with six layers of porcelain tube 4, be wound with resistance wire 3 on the porcelain tube 4, resistance wire 3 is by three phase mains 5 power supplies.Said hollow outer cover 1 is the hollow stainless steel outer cover of the no end that is cuboid, and its outside is symmetrically installed with four trapezes 7.Be used for lifting whole device, convenient moving by driving and trapeze 7 cooperations.Lifting hollow outer cover will heated mold cover during work, with regard to not needing mould is carried out dismounting like this, realizes that the dismounting of exempting from of mould is heated.
