The invention discloses a kind of cap bending die with swing block type die, easily abrade and thinning problem in forming process to solve above-mentioned blank.With the cap bending die of swing block type die, comprise die shoe and be positioned at the punch above upper bolster, vertical through hole is had in the middle part of die shoe, push rod is equipped with in through hole, described upper male mould can vertical motion, and described upper male mould has ladder boss, it is characterized in that, two are provided with the swing block type die of the longitudinal center line symmetry of push rod on described die shoe top, the outer end of swing block type die is hinged on axle, the inner end of swing block type die has straight trough, when swing block type die is positioned at initial position, the end of two cell walls of straight trough is in same level, during blank forming, two straight troughs of swing block type die form die cavity relatively, push rod can the inner end of jack-up swing block type die, the size of the size of die cavity and the ladder boss of upper male mould matches.
Description
Technical field
The present invention relates to a kind of cap bending die with swing block type die.
Background technology
Cap is a kind of conventional part, and it comprises the outside extension of the depressed part of middle U-shaped and both sides, and it adopts bending die to carry out processing and forming usually.As shown in Figure 2, the primary structure of the existing bending die for cap comprises die shoe, be arranged on the lower cavity die on die shoe top, the die cavity of lower cavity die is made up big and down small stepped, upper male mould can be used for punched blank by vertical motion, upper male mould also makes the ladder boss matched with die cavity, but this bending die Problems existing is: in BENDING PROCESS, the shoulder of upper male mould can hinder the rotation of blank, move on exterior angle sweep is continuous, and along with pressing down of punch, blank can be increased gradually by the frictional force of die entrance, the sidewall of blank is easily abraded with thinning.
Summary of the invention
The invention is intended to provide a kind of cap bending die with swing block type die, easily abrade and thinning problem in forming process to solve above-mentioned blank.
The cap bending die with swing block type die in this programme, comprise die shoe and be positioned at the punch above upper bolster, vertical through hole is had in the middle part of die shoe, push rod is equipped with in through hole, described upper male mould can vertical motion, and described upper male mould has ladder boss, it is characterized in that, two are provided with the swing block type die of the longitudinal center line symmetry of push rod on described die shoe top, the outer end of swing block type die is hinged on axle, the inner end of swing block type die has straight trough, when swing block type die is positioned at initial position, the end of two cell walls of straight trough is in same level, during blank forming, two straight troughs of swing block type die form die cavity relatively, push rod can the inner end of jack-up swing block type die, the size of the size of die cavity and the ladder boss of upper male mould matches.
The invention has the advantages that: during processing blank, first flat blank is placed on the end of swing block type die two cell wall, because the end of two cell walls of straight trough when swing block type die is positioned at initial position is in same level, therefore the level of blank can be ensured, then upper male mould moves downward, until the ladder boss contact blank of upper male mould, swing block type die is forced to relatively rotate, the notch of two straight troughs forms die cavity gradually relatively, when the bottom land of two straight troughs is a horizontal plane, shaping end, upper male mould is up, by push rod, workpiece is ejected, swing block type die resets.
The bending die of this programme, when shaping, due to the design of swing block type die, the shoulder of upper male mould can not contact the rotation hindering blank with blank, the sweep mobile range at exterior angle reduces greatly, and the workpiece sidewall quality after therefore shaping is guaranteed, and there will not be scratch or thinning phenomenon.
Further, in order to realize automatically reseting of push rod, be provided with spring mounting seat at the middle part of die shoe, spring mounting seat is hollow tubular, push rod top is provided with the installing plate that can be against die shoe upper surface, and push rod periphery is provided with spring between installing plate and the lower inner wall of spring mounting seat.
Further, between die shoe and swing block type die, also backing plate is provided with.Between die shoe and swing block type die, backing plate is set further, adopts the mode transmitted step by step of power here, the dynamics that is hit of swing block type die can be reduced, improve the intensity of swing block type die.
Further, after shaping, in order to realize automatically reseting of swing block type die, between the inner end and backing plate of swing block type die, be provided with reseting pressuring spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the structural representation of existing cap bending die.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: upper male mould 1, die shoe 2, push rod 3, spring mounting seat 4, spring 5, swing block type die 6, backing plate 7.
Embodiment is substantially as shown in Figure 1: the present embodiment is with the cap bending die of swing block type die, and die shoe is positioned at bottom and is horizontally disposed with, and die shoe top is provided with backing plate, and die shoe is fixedly connected with by four screws with backing plate.Vertical through hole is had in the middle part of die shoe, push rod is equipped with in through hole, spring mounting seat is provided with at the middle part of die shoe, spring mounting seat is hollow tubular, push rod top is provided with the installing plate that can be against die shoe upper surface, and push rod periphery is provided with spring between installing plate and the lower inner wall of spring mounting seat.The above-mentioned spring of the present embodiment is extension spring, has reset response to push rod.
Backing plate top is positioned at its both sides and is respectively equipped with mount pad, and mount pad is c-shaped, together with mount pad is fixed by screws in backing plate.Each mount pad is all rotatably connected to an axle, swing block type die has two and symmetrical with the longitudinal center line of push rod, the outer end of swing block type die is hinged on axle, and the inner end of swing block type die has straight trough, between the inner end and backing plate of swing block type die, be provided with reseting pressuring spring.
When swing block type die is positioned at initial position, the end of two cell walls of straight trough is in same level, and during blank forming, two straight troughs of swing block type die form die cavity relatively, and push rod can the inner end of jack-up swing block type die.Upper male mould is positioned at directly over die cavity, and upper male mould can vertical motion, and upper male mould has ladder boss, and the size of the size of die cavity and the ladder boss of upper male mould matches.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
