The specific embodiment

The utility model is described in further detail below in conjunction with drawings and embodiments:

Referring to Fig. 1-7, a kind of copper bar corner corner cut die set comprises punch 5, die shank 1, fixed head 4, backing plate 3, die 8, following mould bases 9 and top mold frame 2, wherein,

Punch 5 is to be to be provided with one on one of the turning of tetragonal material along its length as the arc groove that runs through of blade and the cross section punch die of three right angles, 52 1 circular arcs 51 that form by cross section;

Backing plate 3 is provided with stepped bore 31 departing from the longitudinal axis of axis centre in length and breadth;

Fixed head 4 and die 8 on depart from the axis of pitch of axis centre in length and breadth, be provided with separately one with corresponding fixing hole 41 of punch 5 shape of cross sections and nicking hole 81, the arc gap in this fixing hole 41 and nicking hole 81 is positioned at the central authorities of fixed head 4;

The upper end of punch 5 is fixed on the backing plate 3 and with the fixing hole 41 of fixed head 4 by screw and matches, and the protruding blade of the lower end of punch 5 cooperates with recessed blade 811 accurate-shearings in the nicking hole 81 of die 8; Copper bar R angle is sheared;

Following mould bases 9 is provided with the discharge opening 91 relative with nicking hole 81 installing on the position of die 8, being shaped as of discharge opening 91 is tetragonal, and the length on each limit is greater than the relative distance between punch 5 four limits.

The quadrangular section of above-mentioned punch 5 pole stocks is foursquare, and the arc radius of above-mentioned arc groove is 1/4th of a square edge lengths.The cooperation of the fixing hole 41 of said fixing plate 4 and the upper end of punch 5 is an interference fit; It is accurate matched in clearance that the shearing of the nicking hole 81 of above-mentioned die 8 and punch 5 lower ends cooperates, the alternate clearance that is not more than 0.2 millimeter.Above-mentioned copper bar corner corner cut die set also comprises rubber press 6, and this rubber press 6 is a cylinder, above-mentioned rubber press 5 one sides of fixing hole 41 other adjacent above-mentioned punch by being bolted to fixed head 4.The quadrangular section of above-mentioned punch 5 lower ends is divided into two parts, and the distance that the sectional plane 53 of band arc gap knife edge part is lower than the plane 54 of another right triangular cross-sectional is 12mm.Two locating pieces 7 are installed on the above-mentioned die 8, and the tetragonal both sides that this two locating piece 7 is adjacent with the arc gap in the nicking hole 81 of above-mentioned die 8 respectively are vertical.
