Abstract
The utility model discloses a centering block type crimping die which comprises a male die, a female die and a centering block. The centering block is cylindrical and arranged inside a cylindrical cavity in the bottom of a female die cavity. The centering block is provided with a notch matched with the male die. A protrusion is arranged on the right side wall of the notch. A semi-circular groove matched with the protrusion is formed in the right side wall of the male die. The bottom of the male die is of an arc-shaped fillet structure. The centering block type crimping die is a composite die which can finish crimping operation within one stroke of a punch, and therefore production cost of crimping operation is lowered, and production efficiency is improved.
Description
Technical field
The utility model relates to the cold punching technology processing technique field, is specifically related to a kind of swing block type crimping mould.
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 the advantage of sharp edge abate in addition.
Common flange operation needs multiple working procedure just can finish, so the processing cost height, and working (machining) efficiency is low.Need design and develop a kind of composite die that can in the punch press one stroke, finish the flange operation, to overcome above-mentioned deficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of swing block type crimping mould, can finish the composite die of flange operation in the punch press one stroke, thereby reduces the production cost of flange operation, and enhances productivity.
To achieve these goals, the technical scheme that the utility model proposes is:
A kind of swing block type crimping mould, 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 pressing mutually of described punch, thereby finished the crimping operation.
As the further improved swing block type crimping mould of the utility model, 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 flange efficiency of operation, and can prevent the projection of described centering block and the stuck situation generation of groove of described punch, thereby raising transaction capabilities, reduce die wear, prolong die life.
As the further improved swing block type crimping mould of the utility model, described elastomer is spring or rubber spring.
Swing block type crimping mould provided by the utility model, 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, mechanical strength height, low, the long service life of use cost.

Fig. 3, swing block type crimping mould 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 to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Shown in Fig. 1-3, the swing block type crimping mould that present embodiment provided, 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 groove 6 pressing mutually 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 flange efficiency of operation, and the groove 6 stuck situations of the projection 5 that can prevent described centering block 3 and described punch 1 take place, thereby raising transaction capabilities, reduce die wear, prolong die life.
The swing block type crimping mould that present embodiment provided, 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, mechanical strength height, low, the long service life of use cost.
