Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of bending diel of converter connector, the interference that occurs between counterdie bending punching pin and the strip when it can prevent feeding.

The technical scheme that realizes above-mentioned purpose is: a kind of bending diel of converter connector, comprise patrix, counterdie, patrix punching pin and elasticity material jacking mechanism, described patrix comprises the upper bolster that connects successively from top to bottom, upper padding plate, train wheel bridge, take off backboard and stripper plate, described counterdie comprises the die shoe that connects successively from bottom to top, lower bolster and lower bolster, described patrix punching pin is fixedly mounted on the described train wheel bridge, described elasticity material jacking mechanism comprises that one is screwed in the set screw of bottom in the liftout hole of described die shoe, one is placed in liftout hole and the spring between the bottom surface of the end face of described set screw and described jigger pin that jigger pin and in the liftout hole of described die shoe is arranged on described die shoe, wherein:

The central authorities of described lower bolster are provided with a lower mode cavity coaxial with the liftout hole of described die shoe, and install one in this lower mode cavity and go into the counterdie bending punching pin that son constitutes by sheath and moulding,

Described sheath is fixed in the lower mode cavity of described lower bolster, its internal face be provided with one with its axial at angle oblique groove/raised line;

The outside wall surface that son is gone in described moulding be provided with described sheath on the adaptive oblique raised line/groove of oblique groove/raised line, described moulding is gone into the mode that son splices at the oblique groove/raised line of described sheath with the oblique raised line/groove on its outside wall surface and is slidably mounted in the inner chamber of described sheath.

The technical scheme of the bending diel of converter connector of the present utility model, counterdie bending punching pin is made the slide block form, counterdie bending punching pin not only can move vertically upward when making liftout, also but level is got out of the way strip to moving, thus the interference between counterdie bending punching pin and the strip when preventing feeding.

The specific embodiment

In order to understand the technical solution of the utility model better, also be elaborated in conjunction with the accompanying drawings below by specific embodiment:

See also Fig. 4 and Fig. 5, the bending diel of converter connector of the present utility model comprises upper die and lower die, patrix punching pin 3 and elasticity material jacking mechanism, wherein:

Patrix comprises from top to bottom the upper bolster 11, upper padding plate 12, the train wheel bridge 13 that connect successively, takes off backboard 14 and stripper plate 15;

Counterdie comprises die shoe 21, lower bolster 22 and the lower bolster 23 that connects successively from bottom to top;

Patrix punching pin 3 is fixedly mounted on the train wheel bridge 13;

The elasticity material jacking mechanism comprises that a set screw 41, of bottom that is screwed in the liftout hole of die shoe 21 is placed in liftout hole and the spring 42 between the bottom surface of the end face of set screw 41 and jigger pin 43 that jigger pin 43 and in the liftout hole of die shoe 21 is arranged on die shoe 21.

The central authorities of lower bolster 23 are provided with a lower mode cavity coaxial with the liftout hole of die shoe 21, and installation one is gone into the son 52 counterdie bending punching pines that constitute by sheath 51 and moulding in this lower mode cavity, wherein:

Sheath 51 is fixed in the lower mode cavity of lower bolster 23, its internal face be provided with one with its axial at angle oblique groove/raised line 50;

Moulding go into son 52 outside wall surface be provided with sheath 51 on the adaptive oblique raised line/groove of oblique groove/raised line 50, moulding is gone into the mode that son 52 splices at the oblique groove/raised line 50 of sheath 51 with the oblique raised line/groove on its outside wall surface and is slidably mounted in the inner chamber of sheath 51.

The mold closing process of the bending diel of converter connector of the present utility model is: mould vertically moves downward under the effect of punch press power, stripper plate 15 and moulding are gone into son 52 and earlier product strip 6 are pushed down, under the active force of patrix, moulding is gone into son 52 along 50 oblique the moving downward of the oblique groove/raised line on the sheath 51, jigger pin 43 goes under son 52 the effect to move downward in moulding, after motion a period of time, patrix punching pin 3 moves downward under the patrix active force, moves to up to punch press and after bottom dead center finishes the formed product process.

The die sinking process of the bending diel of converter connector of the present utility model is: patrix punching pin 3 and upper bolster 11, upper padding plate 12 and train wheel bridge 13 move upward under the effect of punch press power, after motion a period of time, stripper plate 15 and take off backboard 14 and move upward together, son 52 oblique groove/raised line 50 oblique the moving upward at the effect lower edge of jigger pin 43 sheath 51 are gone in moulding simultaneously, thereby got out of the way strip 6, moulding is gone into son 52 and is moved to predefined distance back stop motion, finishes whole die sinking process when patrix moves to the punch press upper dead center position.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
