Abstract
The utility model discloses a kind of annular ceramic member, comprise ceramic member body (1), described ceramic member body (1) has central through hole (11) and torus (12), and the upper and lower surface of described torus (12) all has lower concave part (121) near described central through hole (11) place; Described lower concave part (121) is the first arc chord angle (31) to the transition angle of described central through hole (11) perisporium, the upper and lower surface of described torus (12) is the second arc chord angle (32) to the transition angle of described torus (12) periphery wall, and the upper and lower surface of described torus (12) is three-arc angle (33) to the transition angle of described lower concave part (121).By first arc chord angle of to be radius by lower concave part to the transition angle of central through hole perisporium be 0.25mm, the product after sintering just becomes a natural radius herein.When there being burr, through the process of technical process later, burr will be made to drop.
Description
Technical field
The utility model relates to electronic ceramics product technical field, particularly a kind of annular ceramic member.
Background technology
The pottery of electricity, magnetic property can be utilized in the electronics industry, be called electronic ceramics.Electronic ceramics finally obtains the pottery with New function by the control of effects on surface, crystal boundary and dimensional structure.Can widespread use in the energy, household electrical appliance, automobile etc.
As shown in Figure 1, be in ∠ 90 ° at 01 place, the small sircle hole namely, be embodied on mould is exactly a right cylinder to existing ring-shaped pottery part.And adopt the product of 95 porcelain, the wearing and tearing of 95 pairs of moulds are than faster, are namely very easy to produce burr or burr at 01 place of figure mono-, cause the fraction defective of product very high.
Utility model content
In order to solve the problem of prior art, the utility model embodiment provides a kind of annular ceramic member.Described technical scheme is as follows:
Provide a kind of annular ceramic member, comprise ceramic member body, described ceramic member body has central through hole and torus, and described toric upper and lower surface all has lower concave part near described central through hole place; Described lower concave part is the first arc chord angle to the transition angle of described central through hole perisporium, and the radius of described first arc chord angle is 0.25mm; Described toric upper and lower surface is the second arc chord angle to the transition angle of described torus periphery wall, and the radius of described second arc chord angle is 0.25mm; Described toric upper and lower surface is three-arc angle to the transition angle of described lower concave part, and the radius at described three-arc angle is 0.25mm.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By first arc chord angle of to be radius by lower concave part to the transition angle of central through hole perisporium be 0.25mm, the product after sintering just becomes a natural radius herein.When there being burr, through the process of technical process later, burr will be made to drop.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model currently available products.
Fig. 2 is the structural representation of the annular ceramic member that the utility model embodiment provides.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
Present embodiments provide a kind of annular ceramic member, incorporated by reference to reference to figure 2, comprise ceramic member body 1, ceramic member body 1 has central through hole 11 and torus 12, and the upper and lower surface of torus 12 all has lower concave part 121 near central through hole 11 place.
Lower concave part 121 is the radius of the first arc chord angle 31, first arc chord angle 31 to the transition angle of central through hole 11 perisporium is 0.25mm.
The upper and lower surface of torus 12 is the radius of the second arc chord angle 32, second arc chord angle 32 to the transition angle of torus 12 periphery wall is 0.25mm.
The upper and lower surface of torus 12 is the radius at three-arc angle, three-arc angle 33, the 33 to the transition angle of lower concave part 121 is 0.25mm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
