Description
Technical field
The present invention relates to the sheet metal mould field, relate in particular to a kind of sheet metal component and cut the diel of being convenient to the demoulding behind the curved right angle.
Background technology
Often need to be with its a part of pressing and bending on sheet metal component, the rectangular shape of the needs that the dogleg section that is stamped has, i.e. " L " shape (referring to accompanying drawing 3,4,5), at present, cumbersome to the processing of this sheet metal work, must open resigning hole at mould, otherwise cut curved after, " L " shape ditch can be stuck in and be difficult in the mould taking out, and not only can damage workpiece quality when using specific purpose tool that it is prized, also the easy damaged die; But, opened resigning hole, to cut and will produce burr when curved, this is that goods institute is unallowable, must carry out subsequent treatment, wastes time and energy, processing cost is high.
Summary of the invention
The technical problem that the present invention solves is, provides a kind of sheet metal component to cut the diel of being convenient to the demoulding behind the curved right angle, time saving and energy saving, technique simple, without burr produce, processing cost is low.
The technical solution used in the present invention is:
A kind of sheet metal component is cut the diel of being convenient to the demoulding behind the curved right angle, comprise by cope match-plate pattern, fixing backing plate, fixed head, the upper die body that stripper and drift consist of, by the die backing plate, the lower mold body that concave template and die consist of, described drift on upper die body is respectively square punch, cut oblique impact head and Bending punch, die on lower mold body is respectively the square hole die that matches with square punch, with the bending female die of cutting oblique die and matching with Bending punch of cutting the oblique impact head and matching, the inner chamber section configuration of cutting oblique die is constituted by the inner chamber section configuration of cutting curved rectangular shaped and square hole die on the sheet metal component, and the inner chamber section configuration of square hole die is positioned at the interior angle place of cutting curved rectangular shaped on the sheet metal component; Be provided with the patrix spring between described fixed head and stripper; Described cope match-plate pattern bottom surface is provided with guide pin bushing, and described lower bolster correspondence is provided with guide pillar.
Further, described stripper is provided with the discharging backing plate, and the discharging backing plate is connected with fixed head by the patrix spring.
Further, be fixed with position-limitting pin on the described stripper, this position-limitting pin runs through discharging backing plate, fixed head, fixing backing plate and join with the step-like blind slot type that cope match-plate pattern is offered.
Beneficial effect of the present invention is:
The die of the present invention on lower mold body be respectively the square hole die that matches with square punch, with cut the bending female die of cutting oblique die and matching with Bending punch that the oblique impact head matches, because cutting the inner chamber section configuration of oblique die is constituted by the inner chamber section configuration of cutting curved rectangular shaped and square hole die on the sheet metal component, the inner chamber section configuration of square hole die is positioned at the interior angle place of cutting curved rectangular shaped on the sheet metal component, this step stamping-out can make things convenient for after complete, the smooth demoulding, and is time saving and energy saving, technique is simple; Owing to need not to establish resigning hole, thus without burr produce, processing cost is low; By using discharging backing plate, fixedly backing plate, patrix spring, position-limitting pin etc., make mould move more stability and safety, guaranteed precision.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment:
As shown in drawings, sheet metal component is cut the diel of being convenient to the demoulding behind the curved right angle, comprises that the fixed form of drift in upper die body is same as the prior art by cope match-plate pattern 1, the fixing upper die body that consists of of backing plate 2, fixed head 3, stripper 12 and drift; By the lower mold body that die backing plate 14, concave template 13 and die with blanking hole 17 consist of, the fixed form of die in lower mold body is same as the prior art; Described drift on upper die body is respectively square punch 4, band inclined-plane, bottom 19 cut oblique impact head 5 and Bending punch 6, lay respectively at the diverse location in the upper die body, die on lower mold body is respectively the square hole die 16 that matches with square punch, with the bending female die 22 of cutting oblique die 18 and matching with Bending punch of cutting the oblique impact head and matching, the side of bending female die 22, concave template 13 is provided with bending space 21, inner chamber 20 section configurations of cutting oblique die 18 are constituted by the inner chamber section configuration of cutting curved rectangular shaped 23 and square hole die 16 on the sheet metal component, and the inner chamber section configuration of square hole die 16 is positioned at the interior angle place of cutting curved rectangular shaped 23 on the sheet metal component; 12 of described fixed head 3 and strippers are provided with patrix spring 10; Described cope match-plate pattern 1 bottom surface is provided with guide pin bushing 9, and described lower bolster 14 correspondences are provided with guide pillar 15.
Further, described stripper 12 is provided with discharging backing plate 11, and discharging backing plate 11 is connected with fixed head 3 by patrix spring 10.
Further, be fixed with position-limitting pin 7 on the described stripper 12, this position-limitting pin 7 runs through discharging backing plate 11, fixed head 3, fixing backing plate 2 and join with step-like blind slot 8 types that cope match-plate pattern 1 is offered.
Shenfu figure during work, determines square hole with square punch 4 and square hole die 16 in the sheet metal work upper punch first, and this is the first step; Second step is with cutting oblique impact head 5 and cutting oblique die 18 stamping-outs in the another location, with rectangular-shaped part punching press at an angle, because cutting inner chamber 20 section configurations of oblique die 18 is made of the inner chamber section configuration of cutting curved rectangular shaped 23 and square hole die 16 on the sheet metal component, and the inner chamber section configuration of square hole die 16 is positioned at the interior angle place of cutting curved rectangular shaped 23 on the sheet metal component, therefore, this step stamping-out can make things convenient for after complete, the smooth demoulding; It is rectangular-shaped that the 3rd step was that the part that will be converted into certain angle with Bending punch 6 and bending female die 22 in the another location strikes out, and bending is complete: namely finished rectangular-shaped be " L " shape cut the bending shape mould cut curved after the smoothly demoulding.In the whole operating process, guide pin bushing 9 and guide pillar 15 are auxiliary has realized guiding, and patrix spring 10 can prevent drift undershoot carry and damage mould and can help upper die body to reset well, and this has all guaranteed the orderly function of mould; In addition, position-limitting pin 7 ends expand and are limited in blind slot 15 inside, when being flushed to certain position under the drift can because of the limited pin ends of the cope match-plate pattern section of expanding support stop descending, in the reseting procedure, after moving carry on stripper 12 and the discharging backing plate 11, the position-limitting pin end section of expanding can support the step of blind slot 8, guarantees that mould moves more stability and safety.
