A kind of grinding mould of sheet silicon nitride ceramics heating element
Technical field
The utility model relates to a kind of grinding mould, particularly relates to a kind of grinding mould of sheet silicon nitride ceramics heating element.
Background technology
Sheet silicon nitride ceramics heating element is widely applied in dry combustion method and wet combustion field, but its quality and life-span are the huge obstacles of its development of restriction always, and except its welding quality gone between directly affects, its grinding quality is also its main influence factor.
There is obvious defect in traditional artificial method for grinding, mainly be that grinding quality is unstable, artificial variable is comparatively large, and this also directly affects the welding quality of lead-in wire, and grinding efficiency is also lowly the major reason hindering silicon nitride ceramics heating element fast development in addition.
Utility model content
Technical problem to be solved in the utility model be to provide a kind ofly be convenient to process, improve grinding quality, practicality simple to operate, cost is low, efficiency is high, reusable, can the grinding mould of sheet silicon nitride ceramics heating element of mass production.
In order to solve the problems of the technologies described above, the grinding mould of the sheet silicon nitride ceramics heating element that the utility model provides, bed die is provided with cavity, is provided with paraffin in described cavity.
The foreign minister of described bed die is of a size of 130mm ~ 150mm, is widely of a size of 50mm ~ 100mm outward, and outer height is of a size of 7mm ~ 15mm, and the interior length of described cavity is of a size of 125mm ~ 140mm, and inner width is of a size of 45mm ~ 90mm, and interior height is of a size of 4mm ~ 10mm.
Described cavity is rectangle.
Adopt the grinding mould of the sheet silicon nitride ceramics heating element of technique scheme, its operation principle is: utilize the feature of sheet silicon nitride ceramics heating element and the melting condensation principle of paraffin, design special grinding mould, fixing sheet silicon nitride ceramics heating element product, coordinate suitable processing technology again, finally realize the high-quality of sheet silicon nitride ceramics heating element product and high efficiency grinding.
The beneficial effects of the utility model are: the grinding mould using sheet silicon nitride ceramics heating element, are convenient to Product processing, improve grinding quality, there is practicality simple to operate, cost is low, efficiency is high, reusable, can the advantage such as mass production.
In sum, the utility model be a kind of simple and practical, cost is low, efficiency is high, reusable, can the grinding mould of mass production sheet silicon nitride ceramics heating element.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 2 and Fig. 3, bed die 1 is provided with cavity 16, is provided with paraffin 4 in cavity 16, and the material of bed die 1 is stainless iron.
Particularly, the foreign minister 2 of bed die 1 is of a size of 130mm ~ 150mm, and outer wide 3 are of a size of 50mm ~ 100mm, and outer high 5 are of a size of 7mm ~ 15mm, and the interior length 7 of cavity 16 is of a size of 125mm ~ 140mm, and inner width 8 is of a size of 45mm ~ 90mm, and interior high 6 are of a size of 4mm ~ 10mm.
Preferably, cavity 16 is rectangle.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, sheet silicon nitride ceramics heating element 9 is as shown in Figure 1 put into the cavity 16 on the bed die 1 of grinding mould 14 as shown in Figures 2 and 3, two angle head 10 in the same side as Fig. 4, Fig. 5 or Fig. 6, fit system marshalling shown in Fig. 7, the back side 11 upward or side 12 upward, then by advance in the hot-air oven of 80 DEG C ~ 120 DEG C the paraffin 4 of melting pour in the cavity 16 on bed die 1, be filled in interior length 7, inner width 8, the cavity 16 of interior high 6 compositions is with the gap of sheet silicon nitride ceramics heating element 9, after treating paraffin 4 cooling solidification, be placed in surface grinding machine machine table 15 as shown in Figure 8 together, the magnetic means of surface grinding machine machine table 15 will hold the bed die 1 of fixing stainless iron material, grinding is carried out according to manuscript paper size with skive sheet 13 pairs of sheet silicon nitride ceramics heating elements 9 of surface grinding machine, hot-air oven grinding mould 14 being put into 80 DEG C ~ 120 DEG C after grinding heats, melting and collection paraffin 4, to wait to reuse.
Grinding mould of the present utility model is convenient to product grinding, effectively can improve grinding quality, be a kind of simple and practical, cost is low, efficiency is high, reusable, can the grinding mould of mass production sheet silicon nitride ceramics heating element.
