一种冲孔和u曲模具

Punch a hole and bent mould of U

Abstract

The utility model discloses a punch a hole and bent mould of U goes up the mould including the cope match -plate pattern, upper padding plate and the cope match -plate pattern that set gradually, and the cope match -plate pattern is equipped with mould on the U song, presses the material piece and the drift that punches a hole, and the lower mould is equipped with the bent lower mould of U, punch a hole lower mould and relocation mechanism, on the U song mould locate in the cope match -plate pattern and with upper padding plate fixed connection, in the drift that punches a hole wore to locate to press the material piece, lower mould and relocation mechanism fixed connection punched a hole. The utility model discloses beneficial effect: it is equipped with mould on the U song to go up the mould, press the material piece and punch a hole the drift, the lower mould is equipped with the bent lower mould of U, lower mould and relocation mechanism punch a hole, during the compound die, press the material piece and push down the part, go up the mould downstream, mould and the bent lower mould contact of U on the U song, the completion is bent to the U of part, go up the mould and continue the motion, under the effect of relocation mechanism, the drift that punches a hole contacts with the lower mould that punches a hole, the completion is punched a hole to the part, both can punch a hole, can carry out the U song again, thereby greatly improving production efficienc, and the quality of products can be ensured, at the bottom of the rejection rate, and the production cost of enterprises is lowered.
本实用新型公开了一种冲孔和U曲模具,上模包括依次设置的上模板、上垫板和上模板,上模板设有U曲上模、压料块和冲孔冲头,下模设有U曲下模、冲孔下模和浮动机构,U曲上模设于上模板内并与上垫板固定连接,冲孔冲头穿设于压料块内,冲孔下模与浮动机构固定连接。本实用新型有益效果:上模设有U曲上模、压料块和冲孔冲头,下模设有U曲下模、冲孔下模和浮动机构,合模时,压料块压住零件,上模向下运动,U曲上模与U曲下模接触,完成对零件的U曲,上模继续运动,在浮动机构的作用下,冲孔冲头与冲孔下模接触,完成对零件的冲孔,既可以进行冲孔,又可以进行U曲,大大提高了生产效率,保证产品的质量,废品率底,降低企业的生产成本。
