Wherein, see through the application in this duct 5, can let the compressed air of heat transmission, directly get in the main heat radiation road 12, to improve the radiating rate of integral body.
In above-mentioned, in the said depression slot part 13, also be provided with at least one electrode tip 1 that can prevent and be out of shape, also can supply the heat insulation 6 of the disconnected hot usefulness of insulation.
Wherein, because electrode tip 1 can produce high temperature, so receive the factor affecting of rising-heat contracting-cold, deformation is bigger; And general electrode tip 1 is that spiral shell is located on the hot press, and sees through the application of this kind heat insulation 6, can avoid because deformation; And have influence on the location of electrode tip 1, in addition, more can avoid heat; Be delivered on the hot press, the operator is produced harm or has influence on service life of hot press, let being used that the utility model can feel at ease.
In above-mentioned, said heat insulation 6, it is to be a synthetic stone [CDM].
Wherein, synthetic stone [high-temperature nano composite] is a kind of new material, claims glass fiber reinforced plastic again; It is a kind of glass fibre compound; Whole price, cost are cheap, and have in the environment that temperature raises gradually, still can continue to keep the ability of its physical characteristic.
Secondly, synthesize the low heat conductivity of stone, can guarantee the heat distribution state of electrode tip 1; Make it in hot pressing, reach high-level support effect, and do not have the situation generation of distortion; Place 360 degree and continue severe rugged environment in the short time in the operating temperature of 280 degree; Can not cause lamination to separate yet, and can repeatedly recycle, be the optimal selection of heat insulation 6.
In above-mentioned, said positioner 3, it is first collets 31 that contact with electrode tip 1 surface by;
One can match with first collets 31 clamps second collets 32 of temperature feedback line 2;
At least more than one is fixed in first collets 31 and second collets 32 33 compositions of spiral shell spare on electrode tip 1 surface.
Wherein, see through the application of this kind positioner 3, can accurately locate temperature feedback line 2, and reduce the probability that temperature feedback line 2 is torn, and when temperature feedback line 2 faults, can change fast and locate.
In above-mentioned, said main heat radiation road 12, the end that it is positioned at taper 11 places also is provided with a recess 7;
And aforementioned recess 7, it is to be provided with for being one of following shape: section width less than main heat radiation road 12, section width greater than main heat radiation road 12.
Wherein, by the application of recess 7, letting the bottom better heat-radiation effect in main heat radiation road 12, to promote whole thermal diffusivity, is not the thermal diffusivity of a lift portion, increases the utility model whole service life.
Secondly, see through the application of different recess 7, let the radiating effect of the utility model change, can be applicable in the different hot press processing procedures, increase the application of the utility model.
Comprehensive the above; Can learn that the utility model sees through main radiating block 111 and secondary radiating block 112, reaches the setting of leading heat radiation road 12; Let increase the service life of electrode tip 1; More convenient application and maintenance, compared to traditional soldering tip, the utility model can have more application, practicality, effect property and industry applications.
What should explain at last is: above embodiment is the described technical scheme of unrestricted the utility model in order to explanation the utility model only; Therefore, although this specification has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of invention, and it all should be encompassed in the middle of the claim scope of the utility model.
