Abstract
The invention provides a universal stretch-bending mold of a single-curvature arc section bar. The universal stretch-bending mold comprises a universal mode base and a forming block, wherein the universal mold base is provided with a T-type spout, a movable T-type sliding block is inlaid in the spout, a connecting hole is formed in the T-type sliding block, a forming cambered surface used for stretch-bending is arranged on the forming block, and the forming block is fixed with the T-type sliding block through a connecting piece. The greatest advantage of the universal stretch-bending mold is that the universal mode base is in a universal structure and can be fixed with a stretch-bending machine, and the forming block is a component which can be replaced according to types of different parts.
Description
Technical field
The application relates to the mould of aircraft manufacturing frock class, specifically a kind of general stretch bending mold of single degree arc profile.
Background technology
Stretch bending mold is that the chuck by the stretch benders both arms applies certain axial tension and bending moment to section bar, makes section bar produce certain plastic deformation, blank is bent to the mould of required part shape.
In aircraft development, need a large amount of different size stretch bending of moulding part.Fig. 1 is single degree band angle arc profile part.For the shaping of this type of part,, need to carry out stretch wrap forming with special-purpose stretch bending mould all the time.The shortcoming of existing technology is that each part forming need have a special-purpose stretch bending mould of cover, and this has increased part greatly produces the quantity of matching tooling and manufacture and design the cycle, thereby causes the wasting of resources part production cycle to lengthen.
Summary of the invention
The object of the present invention is to provide a kind of general stretch bending mold that can overcome a kind of single degree arc profile of prior art shortcoming.
A kind of general stretch bending mold of single degree arc profile, contain all round die holder and shaping piece, it is characterized in that described all round die holder has a T-shaped chute, be inlaid with a movably T-shaped slide block in chute, T-shaped slide block is provided with connecting hole, described shaping piece is provided with the shaping cambered surface that stretch bending is used, and shaping block body center also is provided with for fastening through hole, separately has bolt that T-shaped slide block and shaping piece are connected and fixed.
Above-mentioned all round die holder is preferably combined by base and two cover plates of with groove, cover plate and base can be fixed by connector, gap between two cover plates and the groove of base form a T-shaped chute, the bottom of T-shaped chute is that the chute cunning is closed face, the middle part lower surface of T-shaped chute is meshing of chute, the bottom of described T-shaped slide block corresponds to the slide block cunning and closes face, and the middle part upper surface of T-shaped slide block corresponds to meshing of slide block.
In order to adapt to the moulding of different radian parts, above-mentioned shaping piece is a removable sub-assembly preferably, the shaping cambered surface of forming blocks and the shaping radian of product parts coupling, the shaping piece that different parts selection matchings is different.
The great advantage of said structure is that all round die holder is universal architecture, can fix with stretch benders, the shaping piece is a sub-assembly removable according to different part type, and its most useful effect is exactly to have simplified structure and the quantity of stretch bending mold, greatly reduces the cost of aircraft manufacturing.
Below in conjunction with the embodiment accompanying drawing, the application is described in further detail
Description of drawings
Fig. 1 is the structural representation of shaping stretch bending mold
Fig. 2 is T-shaped slide block signal
Fig. 3 is the signal of shaping block structure
Fig. 4 is the cross-section structure signal of shaping stretch bending mold
Number description: 1 all round die holder, 2 shaping pieces; 3 connecting bolts; 4T type chute; 5T type slide block; 6 parts; 7 securing members; 8 first cover plates; 9 second cover plates; 10 shaping cambered surfaces, 11 grooves, 12 chute cunnings are closed face, meshing of 13 chutes, 14 slide block cunnings and are closed meshing of face, 15 slide blocks
The specific embodiment
referring to accompanying drawing, the all round die holder 1 of the moulding stretch bending mold that the application provides is that base and two cover plates (the first cover plate 8 and the second cover plate 9) of the with groove 11 of a rigidity combine, two cover plates are connected securing member 7 and connect with base, gap between two cover plates and the groove of base 11 form a T-shaped chute 4, the two sides of T-shaped chute 4 are that the chute cunning is closed face 12, the middle part lower surface of T-shaped chute is meshing 13 of chute, meshing 13 of this chute is positioned at the cover plate downside of described groove 11 tops, the two sides of T-shaped slide block correspond to the slide block cunning and close face 14, the middle part upper surface of T-shaped slide block corresponds to meshing 15 of slide block, T-shaped slide block 5 can be embedded in the T-shaped chute 4 of all round die holder, and there is connecting hole at the center of T-shaped slide block 5, the outside of shaping piece 2 is useful on the shaping cambered surface 10 of shaping, and there is the boss that can embed the T-shaped chute of all round die holder the lower end of shaping piece, and also there is corresponding connecting hole at the center of shaping piece 2.
Fig. 1 has reflected the shaped state to part 6, symmetrical structures of a tangent bend because of part 6, therefore be inlaid with two independently T-shaped slide blocks 5 in the T-shaped chute 4 of all round die holder, be fixed with respectively a shaping piece 2 on each T-shaped slide block, shaping piece 2 compresses by connecting bolt 3 with T-shaped slide block 5 and rigidly fixes, meshing 15 meshing 13 of chute with the cover plate downside of the slide block of T-shaped slide block 5 is pressed in chute relatively stable, at this moment all round die holder can be fixed on drawing machine tool, implements the stretching to part 6.The application's great advantage is for different part stretch bendings, only needs to change the shaping piece that has with part match and gets final product, and has greatly improved the manufacturing efficient of part, the manufacturing cost of having saved part.
