Description
Technical field
The utility model relates to a kind of sheet metal mould, is particularly related to negative angle bending die tool.
Background technology
Tradition negative angle Bending Mould, have the mould of two kinds of forms, one is a large-sized mould of the whole series, and this whole set of die needs to increase step pitch to provide enough space accommodation space, another is exactly the little die assembly of many cover sizes, and this assembling die production efficiency is lower.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of size little and the mould of the whole series, and the technical scheme adopted is as follows:
Negative angle bending die tool, comprises upper die and lower die;
Described patrix comprises upper bolster, shaping public affairs, fixed head, drive block and stripper plate, and drive block and fixed head are arranged on upper bolster by backing plate; The top of described shaping public affairs is connected on fixed head, and shaping public affairs can around its rotary-top, and the afterbody of shaping public affairs is staking punch, and during shaping public rotary-top, staking punch swings;
Described counterdie comprises die shoe, forming slide, drive block wearing plate, shaping public wearing plate, and described forming slide has guide runner and wear-resisting pressing plate to be formed to move back and forth pair; Wear-resisting pressing plate is arranged on die shoe by fixed head; Also comprise the nitrogen spring be arranged on fixed head, slide block enters sub-one end and is embedded in forming slide, and the other end is connected with nitrogen spring, and nitrogen spring enters son by slide block provides reset drives power for forming slide; Described drive block wearing plate is used for providing spacing for drive block; Described shaping public wearing plate is with inclined-plane, and when the staking punch of the shaping public affairs of described contact of incline plane, the shaping public affairs for patrix provide guiding, drive and limit function.
Wherein, described fixed head has the pilot hole position of circular shape, and the top of shaping public affairs is the dop of corresponding circular shape, afterbody is staking punch, and dop is assemblied in the pilot hole position of fixed head, dop and pilot hole position concentric, when dop rotates in pilot hole position, staking punch carries out swing; Fixed head, at the limited plane in both sides, pilot hole position, is respectively rear confined planes, prosodetic plane, and rear confined planes, prosodetic plane limit the amplitude of fluctuation of shaping public affairs from both sides.
The course of work is:
Negative angle bending die tool open mode, the shaping public affairs of patrix are in the rear confined planes state near fixed head, and the nitrogen spring of stripper plate, counterdie is in off position; Forming slide is in original state, and material strip shifts to feed level under the effect of the buoyance lift parts of other devices;
In the descending process of patrix, after stripper plate starts to contact material strip, patrix continues descending;
Promote forming slide after drive block contact drive block wearing plate to start to move to right, slide block enters son and starts compressed nitrogen spring, and when the straight body face of drive block contacts with forming slide, forming slide arrives operating position, stops moving to right;
After forming slide arrives operating position, stripper plate pushes down material strip;
Shaping public affairs continue descending with patrix, and when shaping public access contacts shaping public wearing plate, shaping public affairs are under the inclined-plane driving effect of shaping public wearing plate, and dop rotates around its center of circle, and shaping public affairs are flapped toward prosodetic plane from rear confined planes; Staking punch starts to extrude material strip and starts to roll over negative angle;
When mould reaches closure state, shaping public affairs complete negative angle flexing movement.
Mould is opened, and forming slide drives shaping public affairs to reset to rear confined planes; Drive block moves, and after forming slide resets completely, stripper plate is opened, and material strip floats.
The negative angle bending die tool that the utility model provides, only need one set of die, and size is little, cost is low.
Accompanying drawing explanation
Fig. 1 is negative angle bending die tool open mode cross-sectional view of the present utility model;
Fig. 2 is negative angle bending die tool closure state cross-sectional view of the present utility model.
Detailed description of the invention
Accompanying drawings detailed description of the invention of the present utility model: as depicted in figs. 1 and 2, negative angle bending die tool, comprises upper die and lower die;
Described patrix comprises upper bolster 10, shaping public 8, fixed head 9, drive block 11 and stripper plate 13, and drive block 11 and fixed head 9 are arranged on upper bolster 10 by backing plate 12;
Described fixed head 9 has the pilot hole position of circular shape, the dop 81 of corresponding circular shape is arranged at the shaping top of public 8, afterbody is staking punch 82, dop 81 is assemblied in the pilot hole position of fixed head 9, dop 81 and pilot hole position concentric, when dop 81 rotates in pilot hole position, staking punch 82 carries out swing; Fixed head 9, at the limited plane in both sides, pilot hole position, is respectively rear confined planes 91, prosodetic plane 92, and rear confined planes 91, prosodetic plane 92 are from the shaping amplitude of fluctuation of public 8 of both sides restriction;
Described counterdie comprises die shoe 4, forming slide 14, drive block wearing plate 1, shaping public wearing plate 7, and described forming slide 14 has guide runner and wear-resisting pressing plate 6 to be formed to move back and forth pair; Wear-resisting pressing plate 6 is arranged on die shoe 4 by fixed head 5; Also comprise the nitrogen spring 3 be arranged on fixed head 5, slide block enters sub 2 one end and is embedded in forming slide 14, and the other end is connected with nitrogen spring 3, and nitrogen spring 3 enters son 2 by slide block provides reset drives power for forming slide 14; Described drive block wearing plate 1 is for providing spacing for drive block 11; Described shaping public wearing plate 7 with inclined-plane, when the shaping public staking punch 82 of 8 of described contact of incline plane, for shaping public 8 of patrix provide guiding, drive and limit function.
The course of work is:
Figure 1 shows that negative angle bending die tool open mode, shaping public 8 of patrix is in rear confined planes 91 state near fixed head 9, and the nitrogen spring 3 of stripper plate 13, counterdie is in off position; Forming slide 14 is in original state, and material strip 15 shifts to feed level under the effect of the buoyance lift parts of other devices;
In the descending process of patrix, after stripper plate 13 starts to contact material strip 15, patrix continues descending;
Promote forming slide 14 after drive block 11 contacts drive block wearing plate 1 to start to move to right, slide block enters son 2 and starts compressed nitrogen spring 3, and when the straight body face of drive block 11 contacts with forming slide 14, forming slide 14 arrives operating position, stops moving to right;
After forming slide 14 arrives operating position, stripper plate 13 pushes down material strip 15;
Shaping public 8 continuation are descending with patrix, and when shaping public 8 touch shaping public wearing plate 7, shaping public 8 under the inclined-plane driving effect of shaping public wearing plate 7, and dop 81 rotates around its center of circle, and shaping public 8 are flapped toward prosodetic plane 92 from rear confined planes 91; Staking punch 82 starts to extrude material strip 15 and starts to roll over negative angle;
