Through the adoption of the left and right symmetric mechanism, the original whole movement of the concave mold inserting blocks is changed into left and right symmetric movement, the concentricity of parts is effectively ensured, the stress is uniform because the internal force can be mutually offset, and the processing precision is high; simultaneously, the mechanism has the advantages of compact structure, little space occupation, short mold development period, and low production cost.
Description
Technical field
The utility model relates to a kind of mould to hole flanging mechanism, belongs 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 hole flanging mechanism is adopted to two when work, make two die plate inserts separately remain on operating position by a drive block to hole flanging die plate insert contraction type structure, and then two wedges are carried out to hole flanging.This structure can make mould discontinuity equalization, poor stability, and very high due to flange hole technology is required the axiality in hole, therefore it directly has influence on the hole flanging quality of parts; Meanwhile, material returned difficulty after this mechanism's hole flanging, can only once turn over the hole of a side, therefore once need two molds to complete to flange hole technology, has greatly strengthened taking up room and processing cost of mould.
Summary of the invention
For improving hole flanging quality, reduce mould and take up room, the utility model proposes a kind of mould to hole flanging mechanism.
For this reason, the technical solution of the utility model 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 respectively on die body, 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, between left slider and right slide block, is provided with spring.
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 matching, and described right drive block lower surface and right slide guide strip lower surface are the inclined-plane matching.
Beneficial effect:
The utility model, by adopting symmetrical formula mechanism, changes the mass motion of original die plate insert into symmetrical motion, has effectively ensured the axiality of zero, internal force cancel out each other make stressed evenly, machining accuracy is high; This mechanism structure compactness, takes up room little simultaneously, has shortened mold developing cycle, has reduced production cost.

Number in the figure is: 1, left drive block; 2, right drive block; 3, left slider guide plate; 4, right slide guide strip; 5, left slider; 6, right slide block; 7, left hole flanging die plate insert; 8, right hole flanging die plate insert; 9, spring; 10, left wedge drive block; 11, right wedge drive block; 12, left wedge hole flanging slide block; 13, right wedge hole flanging slide block; 14, left Burring Punch; 15, right Burring Punch.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, one, to hole flanging die mechanism, comprises drive block, slide guide strip, slide block, hole flanging die plate insert, and drive block, slide guide strip, slide block are arranged on respectively on die body; 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, between left slider 5 and right slide block 6, is connected with spring.
As shown in Figure 1, for improving quality of fit, the upper surface of the lower surface of described left drive block 1 and left slider guide plate 3 is the inclined-plane matching, and the lower surface of the lower surface of described right drive block 2 and right slide guide strip 4 is the inclined-plane matching.
Operation principle:
As shown in Figure 1, when work, cylinder drives left and right driving piece 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 a full circle hole flanging die plate insert of the hole flanging die plate insert of two semicircles composition, this process spring 9 is subject to force compresses.
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.
In the time that hole flanging finishes, drive block moves upward, and now, because the inclined-plane of drive block departs from slide guide strip inclined-plane gradually, spring extends the pressure that discharges storage for slide block backhaul provides power, makes left and right hole flanging die plate insert separately.When 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 finally departs from hole flanging die plate insert, completes whole hole flanging material returned process.
The utility model, by adopting symmetrical formula mechanism, changes the mass motion of original die plate insert into symmetrical motion, has effectively ensured the axiality of zero, internal force cancel out each other make stressed evenly, machining accuracy is high; This mechanism structure compactness, takes up room little simultaneously, has shortened mold developing cycle, has reduced production cost.
