The technical proposal for solving the technical problem of the invention is：The process for stamping of this clamp, U-shaped clamp is by one
Arc and the straight panel at the arc two ends is attached at respectively constituting, the radius of the arc concave profile is r1, described
Arc is b with the thickness of straight panel described in both sides, and the arc concave profile top to the distance of the straight panel termination is
H, using a kind of clamp stamping mold, the clamp stamping mold includes being provided with the cavity plate of arc groove and is provided with the convex of arc drift
Mould, the radius r of the arc drift of the punch-pin is the radius r1+ of the arc concave profile of the U-shaped clamp（0.025 millimeter
~0.035 millimeter）, the radius R1 of the cavity plate arc groove is the radius r and the arc of the arc drift of the punch-pin
Thickness b sums+（0.025 millimeter~0.035 millimeter）；The depth h of the cavity plate arc groove is the arc concave profile
Top to straight panel termination is apart from the 1/2 of H；Blanket locating slot is provided with the cavity plate top surface；The arc drift of the punch-pin passes through
Depression bar is connected with stamping connection plate, the diameter of the thickness e less than the arc drift of the punch-pin of the depression bar；
Including following operating procedure：
A, by the punch-pin by the stamping connection plate on the punch press；
B, blanket to be punched is placed in the blanket locating slot, and makes a side of the blanket and the blanket
The side of locating slot one is concordant；
C, start punch press and drive it and be about to the blanket under arc drift of the punch-pin and extrude to the arc of the cavity plate
In connected in star；
D, the arc drift of the punch-pin is rested on 1 minute~2 minutes in the arc groove of the cavity plate, make to strike out
The straight panel sizing of the arc and arc both sides of the U-shaped clamp of type；
E, drive the arc drift of the punch-pin up, unload the punching press that the U-shaped clamp completes this U-shaped clamp.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：1st, due to convex
Mould arc punch radius r is the radius r1+ of the arc concave profile of U-shaped clamp（0.025~0.035）Millimeter, cavity plate arc
The radius R1 of groove adds for radius r and the arc plate thickness b sums of punch-pin arc drift again+（0.025~0.035）Millimeter；And
The depth h of cavity plate arc groove is arc concave profile top to straight panel termination apart from the 1/2 of H, stamping forming U-shaped clamp
The straight panel of both sides is parallel, and the flatness on U-shaped clamp surface reaches design requirement；2nd, simple structure, cost of manufacture is relatively low, carries significantly
The high manufacturing cycle for shortening mould.
