Abstract
The present invention provides a kind of improved tubular member pipe fitting, includes：Pipe fitting 1, it is characterised in that：Annular protrusion 2 is provided with the outer surface of pipe fitting 1, gap 3 is provided with the annular protrusion 2, gap width L of the gap 3 close to the one end of pipe fitting 1 is less than 1mm, and the pipe fitting 1 is provided with chamfering 4 with the junction of annular protrusion 2.The present invention sets drift, no-go gage on one piece of substrate, and the drift, the size of no-go gage meet the profile, corresponding with the appearance and size of taper bushing of taper bushing, can realize the quick detection to the size of taper bushing, raising checkability.
Description
Technical field
The invention mainly relates to stamping products technical field, more particularly to a kind of improved tubular member flange.
Background technology
The flange of traditional pipe part has certain gap in design, and this gap can cause part in production
The quality of flange face has very great fluctuation process, and product rejection rate is very high always, can not effectively be solved, the production to such product
Producer brings very big puzzlement.
The content of the invention
The present invention provides a kind of improved tubular member flange, and a kind of solution well is provided for the flange design of pipe part
Certainly scheme, in order to achieve the above object, the present invention use following technical scheme：The present invention includes：Pipe fitting 1, it is characterised in that：
Annular protrusion 2 is provided with the outer surface of pipe fitting 1, gap 3 is provided with the annular protrusion 2, the gap 3 is close to pipe fitting
The gap width L of 1 one end is less than 1mm, and the pipe fitting 1 is provided with chamfering 4 with the junction of annular protrusion 2.
Preferential, the diameter D of the pipe fitting 1 is not less than the height d of 2 times of annular protrusions 2.
Preferential, the chamfering 4 is not less than 90 °.
Preferential, the chamfering 4 is fillet.
Preferential, gap width L and gap 3 slit width away from pipe fitting 1 one end of the gap 3 close to the one end of pipe fitting 1
Spend l deviations and be no more than 2%.
Beneficial effects of the present invention：The present invention simplifies production technology, improves product quality, reduces product rejection rate, saves production
Cost.
