Abstract
The invention discloses a hemming die with a swinging block. The hemming die comprises a convex die, a concave die and the swinging block, wherein the cylindrical swinging block is placed in a cylindrical hole chamber in the bottom part of a hole chamber of the concave die and is provided with a gap in match with the convex die; a bump is placed on the right side wall of the gap; a semicircular groove in match with the bump is formed in the right side wall of the convex die; and an arc-shaped fillet structure is formed on the bottom part of the convex die. The hemming die disclosed by the invention is a composite die which can implement hemming operation within one stroke of a punch, so that the producing cost in the hemming operation can be reduced, and the producing efficiency can be improved.
Description
Technical field
The present invention relates to the cold punching technology processing technique field, be specifically related to a kind of swing block type die with edge-folded.
Background technology
Crooked flanging forming is common a kind of processing technology in the cold punching die processing, the workpiece after the processing of edge flanging process, and the mechanical strength at its edge can be significantly increased, and obtains service life prolonging, and has in addition the advantage of sharp edge abate.
Common flange operation needs multiple working procedure just can finish, so processing cost is high, and working (machining) efficiency is low.Need a kind of composite die that can in the punch press one stroke, finish the flange operation of design and development, to overcome above-mentioned deficiency.
Summary of the invention
The object of the present invention is to provide a kind of swing block type die with edge-folded, can in the punch press one stroke, finish the composite die of flange operation, thereby reduce the production cost of flange operation, and enhance productivity.
To achieve these goals, the technical scheme of the present invention's proposition is:
A kind of swing block type die with edge-folded, comprise punch, die, centering block, described centering block is cylindrical and is positioned at the cylindrical cavity of described die vestibule bottom, described centering block has the breach that cooperates with punch, described breach right side wall has projection, described punch right side wall has the semi-circular recesses that cooperates with described projection, and described punch bottom is the curved circular corner structure.When described punch was descending, the left side wall of the breach of described centering block rotated left under the effect of punch left side wall, thereby made the projection of centering block and the groove phase pressing of described punch, thereby finished the crimping operation.
As the further improved swing block type die with edge-folded of the present invention, be provided with the elastomer of horizontal direction between described centering block breach right side wall and the described die right side.Can make centering block have auto-reset function by setting up described elastomer, thereby can further improve the efficient of flange operation, and the stuck situation of the groove that can prevent the projection of described centering block and described punch occurs, thereby raising transaction capabilities, reduce die wear, prolong die life.
As the further improved swing block type die with edge-folded of the present invention, described elastomer is spring or rubber spring.
Swing block type die with edge-folded provided by the present invention, can in the punch press one stroke, finish the composite die of flange operation, thereby reduce the production cost of flange operation, and improve production efficiency, and described simple in structure, be convenient to making, high, low, the long service life of use cost of mechanical strength.
Description of drawings

Fig. 2, stage structures schematic diagram in the punching press of swing block type die with edge-folded;
Fig. 3, swing block type die with edge-folded punching press after-stage structural representation.
1 is punch, and 2 is die, and 3 is centering block, and 4 is breach, and 5 is projection, and 6 is groove, and 7 is elastomer, and 8 is machining sheet.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention is done to describe in further detail, this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Shown in Fig. 1-3, the swing block type die with edge-folded that present embodiment provides, comprise punch 1, die 2, centering block 3, described centering block 3 is cylindrical and is positioned at the cylindrical cavity of described die 2 vestibules bottom, described centering block 3 has the breach 4 that cooperates with punch 1, described breach 4 right side walls have projection 5, and described punch 1 right side wall has and described protruding 5 semi-circular recesses that cooperate 6, and described punch 1 bottom is the curved circular corner structure.When described punch 1 was descending, the left side wall of the breach 4 of described centering block 3 rotated left under the effect of punch 1 left side wall, thereby makes the projection 5 of centering block 3 and the groove 6 phase pressings of described punch 1, thereby finishes the crimping operation.
Further improve as present embodiment, be provided with the elastomer 7 of horizontal direction between described centering block 3 breach, 4 right side walls and described die 2 right sides.Described elastomer 7 is spring or rubber spring.Can make centering block 3 have auto-reset function by setting up described elastomer 7, thereby can further improve the efficient of flange operation, and the groove 6 stuck situations of the projection 5 that can prevent described centering block 3 and described punch 1 occur, thereby raising transaction capabilities, reduce die wear, prolong die life.
The swing block type die with edge-folded that present embodiment provides, can in the punch press one stroke, finish the composite die of flange operation, thereby reduced the production cost of flange operation, and improved production efficiency, and described simple in structure, be convenient to making, high, low, the long service life of use cost of mechanical strength.
