Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to FIG. 1: the utility model provides a notching die for pipe fitting, including upper die base 1 and die holder 2, riser 3 is upwards installed to the top surface of die holder 2, riser 3 is located the top surface middle part of die holder 2, transversely be connected with on riser 3 and be used for the cover to put the pipe fitting and with the plug 4 that die holder 2 paralleled, the top surface of plug 4 is the evagination cambered surface, and seted up die cavity 41 on it, the top surface of upper die base 1 upwards is connected with die shank 5, be equipped with on the bottom surface with die cavity 41 assorted drift 6, drift 6 is gone up horizontal slip and is worn to be equipped with briquetting 7 that can cover plug 4 completely, be connected with a plurality of evenly distributed's elastic component 8 between briquetting 7 and the upper die base 1, specifically, elastic component 8 is the elastic glue stick. Through the structure, the notching die realizes the technical effect of notching the pipe fitting efficiently and with quality guarantee under the matching of the core rod 4, the pressing plate, the concave die groove 41 and the punch 6.
