Detailed description of the invention
Fig. 1 is the schematic perspective view after processing is completed of water meter copper shell；
Fig. 2~6 are the station figure of water meter copper shell processing method in the embodiment of the invention.
In figure: 1- the first cylinder, 2- the second cylinder, 3- the 3rd cylinder, 4- notch, 5- curling piece, 6- protrusion.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.It should be noted that attached drawing of the present invention is all made of simplified form and uses non-essence
Quasi- ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
Water meter copper shell processing method provided by the invention includes the following steps: as shown in Figures 2 to 6
S1: the stretched diameter of raw copper band is met to the second cylinder 2 of final molding size, while prestretching stretching diameter is big
In the 3rd cylinder 3 of final molding size；
S2: stretched diameter meets the first cylinder 1 of final molding size, continues to stretch the 3rd cylinder 3, by the third
3 diameter of cylinder is zoomed in final molding size；
S3: deburring is machined to the upper surface of described the first cylinder 1；
S4: cutting copper shell top edge and gradually push and cut material using formed punch, and disposal molding crimps piece 5, while at
