Abstract
The invention discloses a single-lug airtight nut high-cover flanging mold. The flanging mold mainly comprises a lower mold base, a convex mold, a concave mold, an upper mold base, an upper cushion plate, a beating plate, a positioning nail, an unloading plate and a lower cushion plate; the flanging mold adopts a closed structure with guidance; a mold handle is arranged in the center position of the upper mold base; the beating rod is arranged in the center position of the mold handle; the positioning nail is in threaded connection to the convex mold; and the unloading plate is provided with a concave table having consistent shape with a scrap edge. The flanging mold adopts a closed guide structure with a guide column and a guide sleeve in middle; the positioning nail is in threaded connection to the convex mold, so that the machining of the flanging convex mold is simplified; and the unloading plate is designed with the concave table having consistent shape with the scrap edge, the positioning in flanging is convenient.
Description
Technical field
The present invention relates to a kind of monaural airtight nut height cover flange die, belong to non-homogeneous flange dark cylinder thin-walled parts processing technique field.
Background technology
Airtight nut height cover (Q/EZ215-92) of monaural shown in Fig. 1,2,3, belong to special flange part, this part comprises cover body, and cover body is the cylinder of top seal.The side, bottom of cover body is provided with the auricle of band flange, and auricle is provided with fixing hole.During use, coat anti-corrosive grease by the cover body of this part, cover airtight nut, to prevent airtight nut corrosion, be then connected with matrix through the fixing hole on this part auricle with screw.This part will have following characteristics; 1, the thickness of this part only has 0.8mm, belongs to thin-walled parts.2, cover material adopts rustproof aluminium sheet LF21,3, the auricle on the right side of cover body is longer, and the flange of the other both sides of cover body is very little, makes the length L of part much larger than width W, if auricle also to be regarded as the flange of covers edge, the flange of this part is extremely uneven.4, this part cover body height H is greater than the outer diameter D of cover body, belongs to the dark cylindrical structure that one end is closed.
Summary of the invention
The present invention solves in prior art and has problems, thus provides a kind of monaural airtight nut height cover flange die.
A kind of monaural airtight nut height cover flange die, mainly comprises die shoe 1, punch 5, die 6, upper bolster 12, upper padding plate 13, re-packs 14, locating pin 15, stripper 16 and lower bolster 19; This flange die adopts the enclosed construction of tape guide, and described upper bolster 12 center is provided with die shank 10, and die shank 10 center is provided with makes bar 9; Described locating pin 15 is threaded connection on punch 5; Described stripper 16 is provided with the concave station consistent with trimming profile.
Described stripper 16 is held up by pusher.
Adopt the beneficial effect of technique scheme:
1) the present invention adopts closed middle guide pillar, guide pin bushing guide frame.
2) locating pin of the present invention is threaded connection on punch, simplifies the processing of flanging die.
3) stripper of the present invention is designed with the concave station consistent with trimming profile, facilitates during flange and locate.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.But not as any limitation of the invention foundation.
A kind of monaural airtight nut height cover flange die, mainly comprises die shoe 1, punch 5, die 6, upper bolster 12, upper padding plate 13, re-packs 14, locating pin 15, stripper 16 and lower bolster 19; This flange die adopts the enclosed construction of tape guide, and described upper bolster 12 center is provided with die shank 10, and die shank 10 center is provided with makes bar 9; Described locating pin 15 is threaded connection on punch 5; Described stripper 16 is provided with the concave station consistent with trimming profile, facilitates during flange and locates.
Described stripper 16 is held up by pusher.
Operation principle of the present invention and forming process:
Flange die mould is placed on forcing press (J23-25T) workbench, first that patrix is fastening, then with pressing plate, counterdie is compressed, starting pressure machine work subsequently, slide block rises, mold open, airtight for monaural after trimming nut height cover semi-finished product are placed in the concave station of stripper 16, step on foot-operated, press ram is descending, flanging die 5 enters in die 6 until bottom dead centre, parts flanged-edge is shaped, then press ram rises, part is stayed in die 6 due to the effect of liftout attachment, when press ram rises, make bar 9 to encounter crossbeam part is got from die 6, complete a punching course.
