Abstract
The utility model discloses a die for manufacturing screws with flat gaskets and elastic gaskets. The die comprises a rectangular solid die body and tooth patterns arranged on the surface of the body, wherein a lug boss is further arranged on the upper surface of the body, the lug boss and the body are integrally formed, and the same tooth patterns are further arranged on the upper surface of the lug boss. The screw thread rolling machine of the die can be used for manufacturing screws with the flat gaskets and the elastic gaskets and the H values of the screws with the flat gaskets and the elastic gaskets are smaller than the total value of the h1 and the h2, so as to meet the requirements of application under special assembly conditions.
Description
Technical field
The utility model relates to the screw dimension measuring implement, more particularly, relates to and a kind ofly is used to make that band is flat, the dental lamina of bullet pad screw.
Background technology
The conventional mould that dental lamina is used for the threading machine, it is used for the moulding of screw thread.See also Fig. 1～shown in Figure 3, the dental lamina body 1 that common dental lamina generally comprises rectangular body be located at body 1 lip-deep tooth line 2.Adopt that common pressing plate production band is flat, during bullet pad screw 3, the H value of screw 3 must so also be to define equally in the securing member standard greater than h1 with h2's with value (h1 and h2 are respectively the width of bullet pad 4 and plain cushion 5).But, in some special assembling environment, need that the H value is flat less than the band of h1 and h2 and value, bullet pad screw, have very high firmness in order to guarantee the part that in this special assembling environment, is assembled, become flexible preventing.
For this reason, need a kind of new dental lamina, can be used in the screw of special assembly environment with making.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides and a kind ofly is used to make that band is flat, the dental lamina of bullet pad screw, can be applicable to make H value less than the band of h1 and h2 and value put down, bullet pad screw.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This is used to make, and band is flat, the dental lamina of bullet pad screw comprises the dental lamina body of rectangular body and be located at the tooth line on the body surface that also be provided with a boss on the upper surface of described body, boss and body are integrally formed, and the boss upper surface also is provided with same tooth line.
In technique scheme; Make being used to of the utility model that band is flat, the dental lamina of bullet pad screw comprises the dental lamina body of rectangular body and is located at the tooth line on the body surface; Also be provided with a boss on the upper surface of body; Boss and body are integrally formed, and the boss upper surface also is provided with same tooth line.Adopt the threading machine of this dental lamina can produce band flat, the bullet pad screw of H value, to satisfy the application of special assembly environment less than h1 and h2 and value.
Description of drawings
Fig. 1 is the structure chart of the common dental lamina of prior art;
Fig. 2 is that band is flat, the structure chart of bullet pad screw;
Fig. 3 is that band is flat, the structure chart of putting down, play pad of bullet pad screw;
Fig. 4 is the structural representation of the dental lamina of the utility model.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also shown in Figure 4; Make being used to of the utility model that band is flat, the dental lamina and the prior art of bullet pad screw are basic identical; Equally also comprise the dental lamina body 1 of rectangular body and be located at body 1 lip-deep tooth line 2, different is also to be provided with a boss 6 on the upper surface of described body 1; Boss 6 is integrally formed with body 1, and boss 6 upper surfaces also are provided with same tooth line 2.When making this dental lamina, can adopt existing common dental lamina, calculate L1, L2, the L3 size of correspondence, process this boss 6 through equipment at the upper surface of dental lamina then and get final product according to the requirement of different screw H values and h1, h2 size.
During use, be assembled to this dental lamina on the common threading machine after, just can produce and have that the H value is flat less than the band of h1 and h2 and value, bullet pad screw.For example; The band of JIS standard definition M3.0*0.5 specification is flat, the H of bullet pad screw, h1, h2 size are respectively " H≤3.0, h1 ≈ 1.6, h2 ≈ 0.5, unit millimeter ", during with original common dental lamina production; The H value is between 2.3～3.0; And the dental lamina that adopts the utility model then can guarantee the H value below 2.1, to satisfy the application demand of special assembly environment when producing.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (1)
1. one kind is used to make that band is flat, the dental lamina of bullet pad screw, the dental lamina body that comprises rectangular body be located at the tooth line on the body surface, it is characterized in that:
Also be provided with a boss on the upper surface of described body, boss and body are integrally formed, and the boss upper surface also is provided with same tooth line.
