Background technology
Certain type locomotive pedal need the shape of the circular arc wave otch processed see Fig. 1, the line style of the wave otch 1 processed by the identical circular arc wave of 2 to 20 shapes linearly head and the tail connect to form, upper circular arc is stated wave otch 1 and is positioned on sheet metal, and the thickness of sheet metal is 1mm ~ 4mm.The arc radius that circular arc states wave is 1mm ~ 10mm.Current employing die cutting die Machining Arc wave otch, the structure of the die-cut formpiston used is see Fig. 2, the lower end of die-cut formpiston 2 is with die-cut sword 3, the right surface of die-cut formpiston 2 is with the wave profile consistent with the line style of circular arc wave otch 1, and the line style that die-cut sword 3 lower end cusp is formed is identical with the line style of circular arc wave otch 1.In the longitudinal profile of the normal of the wave formed along die-cut sword 3 lower end cusp, the left hand edge line of die-cut sword 3 section is straight line, forms wedge shape with the right hand edge line of die-cut sword 3 section.Its shortcoming is: the poor rigidity of die-cut sword 3, when die-cut, tipping phenomenon easily occurs, and causes die-cut formpiston to scrap, shortens the service life of die-cut formpiston, reduce production efficiency.
Summary of the invention
The purpose of this utility model is: the die-cut formpiston for die-cut wave otch proposing a kind of improvement, to improve the rigidity of die-cut sword 3, when avoiding die-cut, tipping phenomenon occurs, extends the service life of die-cut formpiston, enhance productivity.
The technical solution of the utility model is: for the die-cut formpiston of die-cut wave otch, the line style of the circular arc wave otch 1 processed by the identical circular arc wave of 2 to 20 shapes linearly head and the tail connect to form, the arc radius that circular arc states wave is 1mm ~ 10mm, above-mentioned circular arc wave otch 1 is positioned on sheet metal, and the thickness of sheet metal is 1mm ~ 4mm; The lower end of said die-cut formpiston 2 is with die-cut sword 3, and the right surface of die-cut formpiston 2 is with the wave profile consistent with the line style of circular arc wave otch 1, and the line style that die-cut sword 3 lower end cusp is formed is identical with the line style of circular arc wave otch 1; It is characterized in that: in the longitudinal profile of the normal of the wave formed along die-cut sword 3 lower end cusp, the circular arc line 5 of the left hand edge line of die-cut sword 3 section to be radius be R, the center of circle O of circular arc line is a to the distance of the right hand edge line 4 of die-cut sword 3 section, and the center of circle O of circular arc line is b to the distance of cusp place, die-cut sword 3 lower end horizontal plane; A=2mm ~ 5mm, b=12mm ~ 15mm.
The utility model has the advantages that: the die-cut formpiston for die-cut wave otch proposing a kind of improvement, substantially increases the rigidity of die-cut sword 3, when avoiding die-cut, tipping phenomenon occurs, extend the service life of die-cut formpiston, improve production efficiency.An embodiment of the present utility model, prove through test, production efficiency improves more than 10 times.

Detailed description of the invention
Below the present invention is described in further details.See Fig. 3, for the die-cut formpiston of die-cut wave otch, the line style of the circular arc wave otch 1 processed by the identical circular arc wave of 2 to 20 shapes linearly head and the tail connect to form, the arc radius that circular arc states wave is 1mm ~ 10mm, above-mentioned circular arc wave otch 1 is positioned on sheet metal, and the thickness of sheet metal is 1mm ~ 4mm; The lower end of said die-cut formpiston 2 is with die-cut sword 3, and the right surface of die-cut formpiston 2 is with the wave profile consistent with the line style of circular arc wave otch 1, and the line style that die-cut sword 3 lower end cusp is formed is identical with the line style of circular arc wave otch 1; It is characterized in that: in the longitudinal profile of the normal of the wave formed along die-cut sword 3 lower end cusp, the circular arc line 5 of the left hand edge line of die-cut sword 3 section to be radius be R, the center of circle O of circular arc line is a to the distance of the right hand edge line 4 of die-cut sword 3 section, and the center of circle O of circular arc line is b to the distance of cusp place, die-cut sword 3 lower end horizontal plane; A=2mm ~ 5mm, b=12mm ~ 15mm.
Cut the material selection 65Mn of formpiston 2, quenching hardness is HRC55 ~ 58.
Operation principle of the present utility model is: this die-cut formpiston 2 is no waste mine Punching Technology circular arc wave otch 1, because tipping phenomenon easily occurs universal mold steel Cr12MoV, so this mold materials selects rigidity and the reasonable spring steel 65Mn of elasticity.Quenching hardness is when mould carries out routinely, and tipping phenomenon easily occurs die-cut formpiston, and through many experiments, material quenching hardness is decided to be HRC55 ~ 58.The circular arc line 5 of the left hand edge line of die-cut sword 3 section to be radius be R, through many experiments, selects R value to be 15.When R value is constant, a size increases gradually, and when b size then synchronously reduces gradually, cutting edge tends to sharp gradually, and die-cut part thickness thickens, but now tipping phenomenon easily occurs cutting edge; When R value is constant, a size reduces gradually, and when b size then synchronously increases gradually, cutting edge is rust gradually, and now tipping phenomenon is less likely to occur cutting edge, thus extends die life.
