Abstract
The utility model discloses an abnormal shape punching press gasket is formed by the whole punching press of sheet metal, its characterized in that: at the regional upwards sphere of uplift that forms of central authorities, the top center of sphere is equipped with circular through -hole after the sheet metal punching press, and the sphere is offered one along radial orientation and is cut off the line, cuts off line one end and extends to circular through -hole, and the other end extends to the start edge line of sphere uplift, and sphere elasticity about cutting off the position that the line cut off staggers. The utility model discloses have cambered surface and spring washer's characteristics concurrently, the place is fastened in the connection that is applicable to the cambered surface contact.
Description
Technical field
This utility model relates to a kind of special-shaped punching press pad being applied to cambered surface contact connection fastening place.
Background technology
In some connection fastening places of automotive interior, often connecting fastening face is cambered surface, and so existing elastic washer cannot be suitable for, and arc pad does not have elasticity, and connection reliability is poor, and after being fastenedly connected, easily appearance loosens.
Summary of the invention
In view of the deficiency of background technology, the purpose of this utility model is to provide a kind of feature having cambered surface and elastomeric pad concurrently, it is adaptable to cambered surface contact connects the special-shaped punching press pad in fastening place.
For this, this utility model adopts following scheme to realize:
Special-shaped punching press pad, it is stamped to form by sheet metal entirety, it is characterized in that: after sheet metal punching press, form the sphere upwards swelled at middle section, the top center of sphere is provided with manhole, sphere radially offers a cutting line, cutting line one end extends to manhole, and the other end extends to the start edge line of sphere protuberance, and sphere staggers in the position that cutting line cuts off elasticity up and down.
Sheet metal after punching press is rectangular shape, and rectangle is provided with four downward projection of punching press salient points near the position of four corners.
After adopting technique scheme, the sphere of punching press pad enables to use as arc pad, and sphere staggers in the elasticity up and down of off-position and enables to use as elastomeric pad, therefore, this utility model has the feature of cambered surface and elastomeric pad concurrently, can be applicable to the connection fastening place of cambered surface contact very well.
Accompanying drawing explanation
This utility model has drawings described below:
Fig. 1 is the three-dimensional structure diagram of special-shaped punching press pad;
Fig. 2 is the vertical view direction plane figure of special-shaped punching press pad.
Detailed description of the invention
As shown in the figure, special-shaped punching press pad of the present utility model, it is stamped to form by sheet metal 1 entirety, form the sphere 2 upwards swelled at middle section after sheet metal 1 punching press, the top center of sphere 2 is provided with manhole 3, and sphere 2 radially offers a cutting line 4, and cutting line 4 one end extends to manhole 3, the other end extends to the start edge line 6 of sphere protuberance, and the position A elasticity up and down that sphere 2 cuts off at cutting line 4 staggers. Sheet metal 1 after punching press is rectangular shape, and rectangle is provided with four downward projection of punching press salient points 5 near the position of four corners.
Above-mentioned special-shaped punching press pad, its sphere enables to use as arc pad, and sphere staggers in the elasticity up and down of off-position and enables to use as elastomeric pad, therefore, have the feature of cambered surface and elastomeric pad concurrently, the connection fastening place of cambered surface contact can be applicable to very well.
