Mold for rotating flanging

Abstract

The invention relates to a die which can carry out the flanging rotatablely; the die comprises an upper die seat, a lower die seat and a material pressing device; an inclined wedge sliding block is connected with the upper die seat and can move to the left side and right side; a returning spring component is arranged between the inclined wedge sliding block and the upper die seat; an inclined wedge fixed seat is arranged on the lower die seat; the die of the invention is characterized in that a flanging cutter block is arranged at the lower left end of the inclined wedge sliding block; an inclined wedge rotation shaft is arranged on the inclined wedge fixed seat and is provided with a concave trough; the right side of the bottom of the concave trough is corresponding to the lower end of the inclined wedge sliding block; the left side of the bottom of the concave trough is corresponding to the lower end of the flanging cutter block; the left side wall of the concave trough is corresponding to the lower part of the left side of the flanging cutter block; a guiding plate is connected on the inclined wedge fixed seat by a nitrogen spring; the left side of the upper part of the guiding plate is corresponding to the inclined surface of the right side of the inclined wedge sliding block; the right side of the lower part of the guiding plate is closely attached to the right side wall of the concave trough on the inclined wedge rotation shaft. The die of the invention has the advantages of simple device, small volume as well as smart and stable actions.

Description

technical field [0001] The invention relates to a flanging mold, in particular to a rotating flanging mold. Background technique [0002] Flanging refers to a stamping process that uses a mold to turn the edge of the sheet into a vertical edge. If the flanging exists in the punching direction such as Figure 4 For the negative angle shown, there is a problem of difficulty in picking up parts after flanging, so all side flanging molds require a double-acting mold device. This kind of mold device is complex, bulky, inflexible in movement, and the cost of the mold is also high. Contents of the invention [0003] The object of the present invention is to provide a mold for rotating flanging, which has simple mechanism, flexible action, small volume, and can remove workpieces conveniently. [0004] A mold for rotating flanging according to the present invention comprises an upper mold base and a lower mold base, and a presser connected to the upper mold base; the wedge sliding...
