Application number is 201220349243.2 Chinese patent, a kind of device that utilizes microwave energy evenly to heat is disclosed, comprise guided wave groove (1) and mould (4), on fixing respectively on top board in guided wave groove (1) and base plate, lower support frame (2, 3), a left side for described mould (4), on right biside plate, be respectively equipped with the guided wave piece (4a) of Mitsubishi's cylindricality, described mould (4) middle part is provided with the placed cavity (4b) of material to be processed, on described, lower support frame (2, 3) be wedge, on described, lower support frame (2, 3) between, form a wedge type chamber, described mould (4) is the wedge identical with this wedge type chamber size, described mould (4) is installed on, lower support frame (2, 3) in the wedge type chamber between.By two bracing frames and the equal support wedge shape of mould, like this, microwave enters from thicker one end of mould, and the entrance that is equivalent to microwave broadens, outlet narrows, although microwave energy can be decayed because of the absorption of material to be processed, because mould narrows gradually, microwave energy is gathered together in mould, can reduce like this decay of microwave energy, even can make microwave energy increase to some extent, improve the utilization ratio of microwave, make the material physical properties that processes even.
But said apparatus only can be applicable to the material that material to be processed is rectangle.When material to be processed becomes arc material, as automobile damping spring steel, with device above, just can not ensure thermally equivalent, because the propagating characteristic of microwave energy is energy maximum placed in the middle, successively decrease gradually to both sides, therefore, arc part can not get uniform heating in this device.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of microwave energy that utilizes evenly to heat the device of producing arc part, and during with this device heating arc part, the temperature everywhere of arc part is basically identical, and the material physical properties of producing is even.
To achieve these goals, the technical solution of the utility model is as follows: a kind of microwave energy that utilizes evenly heats the device of producing arc part, comprise waveguide (1), it is characterized in that: described waveguide (1) is deep-slotted chip breaker, its cross section is rectangle, the long a of this waveguide (1) is 12cm, wide b is 25cm, on top board in described waveguide (1) and base plate, be respectively equipped with, lower support frame (2, 3), on described, lower support frame (2, 3) be the arc piece identical with the crooked radian of guided wave groove (1), and on described, lower support frame (2, 3) near waveguide (1), the thickness of microwave import department is less than the thickness near waveguide (1) microwave exit, upper, lower support frame (2, 3) mould (4) is installed in the camber chamber between, described mould (4) is also the arc piece identical with waveguide (1) bending direction, in described mould (4), be provided with the to be processed material die cavity (4b) identical with waveguide (1) crooked radian, in the both ends of the surface of described mould (4), be respectively equipped with arc guided wave piece (4a), the cross section of described arc guided wave piece (4a) is two triangles that limit is arc-shaped side wherein.
In technique scheme: described micro-wave frequency is 915MHz.
Adopt technique scheme, guided wave groove is designed to arc, and the long a of guided wave groove is 12cm, wide b is 25cm.The microwave that can ensure this frequency enters in guided wave groove, and the design of waveguide assembly radian is conducive to microwave and constantly reflexes in mould, does not therefore dissipate.Equally, bracing frame is set, bracing frame is also arc frame, and the thickness of the import department of bracing frame is narrower, that is to say, mould is large at the thickness at this place, the entrance width of microwave is large, exit width is little, although microwave energy can be decayed because of the absorption of material to be processed, but because mould narrows gradually, microwave energy is gathered together in mould, can reduce like this decay of microwave energy, even can make microwave energy increase to some extent, improve the utilization ratio of microwave, through measuring, this device is in the time of heating arc part, the initiating terminal of this arc part, the temperature of middle part and tail end is basically identical, make the material physical properties that processes even.
As preferably: described mould (4) is made up of silica glass, and described upper and lower bracing frame (2,3) is made up of cellular polyethylene.The material of mould has stronger absorption microwave ability.
As preferably: the thickness of the thicker end of described mould (4) be die cavity (4b) height 7-11 doubly, the thickness of the thinner end of described mould (4) be die cavity (4b) height 1-3 doubly.Can make like this attenuation rate of microwave energy be reduced to minimum, even can make the attenuation rate of microwave energy become negative value.
Beneficial effect: the utility model is reasonable in design, simple in structure, low cost of manufacture, can effectively solve the problem of prior device microwave energy decay, and this device is also applicable to the preparation of arc part simultaneously.
