By means of the left and right symmetric structure, the overall motion of original female die inserts is changed into left and right symmetric motion, so that the coaxiality of parts is effectively guaranteed, the internal force is cancelled out to enable stress to be even, and the machining accuracy is high; and meanwhile, the mechanism is compact in structure and small in occupied space, the die development period is shortened, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of mould to hole flanging mechanism, belong to diel manufacturing technology field.
Background technology
Be a kind of common technique in parts punch forming process to flange hole technology, it plays great role in Design of Dies.
At present, existingly adopt two to make two die plate inserts separately remain on operating position by a drive block to hole flanging die plate insert contraction type structure during work to hole flanging mechanism, and then hole flanging is carried out to two wedges.This structure can make mould discontinuity equalization, poor stability, and owing to requiring very high to flange hole technology to the axiality in hole, therefore it directly has influence on the hole flanging quality of parts; Meanwhile, after this mechanism's hole flanging, material returned difficulty, once can only turn over the hole of side, therefore once need two molds to flange hole technology, greatly increase taking up room and processing cost of mould.
Summary of the invention
For improving hole flanging quality, reduce mould and take up room, the present invention proposes a kind of mould to hole flanging mechanism.
For this reason, technical scheme of the present invention is: a kind of to hole flanging die mechanism, comprise drive block, slide guide strip, slide block, hole flanging die plate insert, drive block, slide guide strip, slide block are arranged on die body respectively, it is characterized in that: described is symmetrical formula structure to hole flanging die mechanism, described drive block comprises left drive block and right drive block, described slide guide strip comprises left slider guide plate and right slide guide strip, described slide block comprises left slider and right slide block, and described hole flanging die plate insert comprises left hole flanging die plate insert and right hole flanging die plate insert; Described left drive block is positioned at the top corresponding with left slider guide plate, and right drive block is located at the top corresponding with right slide guide strip, and described left slider is positioned at the inner side corresponding with left slider guide plate, and right slide block is positioned at the inner side corresponding with right slide guide strip; Described left hole flanging die plate insert is arranged on left slider, and right hole flanging die plate insert is arranged on right slide block, is provided with spring between left slider and right slide block.
The one of technique scheme is improved and is: for improving quality of fit, described left drive block lower surface and left slider guide plate upper surface are the inclined-plane matched, and described right drive block lower surface and right slide guide strip lower surface are the inclined-plane matched.
Beneficial effect:
The present invention, by adopting symmetrical formula mechanism, changing the mass motion of original die plate insert into symmetrical motion, effectively ensure that the axiality of zero, internal force is cancelled out each other and is made uniform force, and machining accuracy is high; This mechanism structure is compact simultaneously, takes up room little, shortens mold developing cycle, reduce production cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of to hole flanging die mechanism, comprise drive block, slide guide strip, slide block, hole flanging die plate insert, drive block, slide guide strip, slide block are arranged on die body respectively; Described is symmetrical formula structure to hole flanging die mechanism, described drive block comprises left drive block 1 and right drive block 2, described slide guide strip comprises left slider guide plate 3 and right slide guide strip 4, described slide block comprises left slider 5 and right slide block 6, and described hole flanging die plate insert comprises left hole flanging die plate insert 7 and right hole flanging die plate insert 8; Described left drive block 1 is positioned at the top corresponding with left slider guide plate 3, and right drive block 2 is located at the top corresponding with right slide guide strip 4, and described left slider 5 is positioned at the inner side corresponding with left slider guide plate 3, and right slide block 6 is positioned at the inner side corresponding with right slide guide strip 4; Described left hole flanging die plate insert 7 is arranged on left slider 5, and right hole flanging die plate insert 8 is arranged on right slide block 6, is connected between left slider 5 with right slide block 6 with spring.
As shown in Figure 1, for improving quality of fit, the described lower surface of left drive block 1 and the upper surface of left slider guide plate 3 are the inclined-plane matched, and the described lower surface of right drive block 2 and the lower surface of right slide guide strip 4 are the inclined-plane matched.
Operation principle:
As shown in Figure 1, during work, cylinder drives left and right driving block to move downward, and left drive block 1 promotes left slider guide plate 3 and moves right, and left slider guide plate 3 promotes left slider 5 and left hole flanging die plate insert 7 mounted thereto moves right together; Simultaneously, the right drive block 2 on opposite promotes right slide guide strip 4, right slide block 6 and right hole flanging die plate insert 8 mounted thereto together to left movement, until the hole flanging die plate insert of two semicircles forms a full circle hole flanging die plate insert, this process spring 9 forced compression.
As shown in Figure 2, now, cylinder drives left wedge drive block 10 and right wedge drive block 11 to move downward, and left wedge drive block 10 promotes left wedge hole flanging slide block 12 and left Burring Punch 14 moves right; Meanwhile, right wedge drive block 11 promotes right wedge hole flanging slide block 13 and right Burring Punch 15 to left movement, enters above-mentioned hole flanging die and realizes flange hole technology.
At the end of hole flanging, drive block moves upward, and now because the inclined-plane of drive block departs from slide guide strip inclined-plane gradually, the pressure that spring elongates release stores provides power for slide block backhaul, makes left and right hole flanging die plate insert separately.While drive block moves upward, wedge drive block also moves upward, and wedge hole flanging slide block and Burring Punch are divided right and left, and final disengaging hole flanging die plate insert, namely completes whole hole flanging material returned process.
The present invention, by adopting symmetrical formula mechanism, changing the mass motion of original die plate insert into symmetrical motion, effectively ensure that the axiality of zero, internal force is cancelled out each other and is made uniform force, and machining accuracy is high; This mechanism structure is compact simultaneously, takes up room little, shortens mold developing cycle, reduce production cost.
