Abstract

The invention provides a forming method and mold for a multi-reinforcing-rib sheet metal part rubber bag made from a plate. An unfolded raw material of a multi-reinforcing-rib sheet metal part is contained. The mold comprises a mold base body and a limiting frame; the mold base body is in a blocky shape similar to the shape of the sheet metal part; the upper surface of the mold base body is provided with a forming face corresponding to the multi-reinforcing-rib sheet metal part; an annular process edge is arranged around the forming face; the limiting frame is of an annular structure matched with the process edge of the mold base body; the unfolded raw material is placed on the forming face of the mold base body; the outer contour of the unfolded raw material is limited by the limiting frame; and forming is performed through rubber bag pressure.

Description

A kind of plate system many reinforcements sheet metal component rubber pocket manufacturing process and shaping dies

Technical field:

The application relates to the sheet metal component rubber pocket forming technique in aircraft manufacturing field, and specifically one Plant plate system many reinforcements part rubber pocket manufacturing process and shaping dies.

Background technology

In aircraft manufacturing, sheet metal component rubber pocket shapes is a kind of common forming and machining method, logical Often sheet metal component shapes needs to position with mould by pin hole.Known in take cotter nail method master Having two kinds, one is to add region and take two or more pin hole processed launching diagonal angle outside woollen, Its major defect be shape after need cutting to add pin auricle；Two is to reduce cutting, directly Connecing and be taken at by pin hole on expansion woollen at diagonal angle, its major defect is that rubber pocket shapes diagonal angle side Limit material to pin hole inwardly to supplement, cause deformation inequality to cause part distortion, warpage, open The problem such as split.

Solution to the problems described above mainly has two methods at present, and one is to use rigidity fixture solid After figuration, part carries out machine and adds milling and add pin auricle；Two is that region uneven to deformation uses Aluminum hammer is used to tap smoothing.It is known in panel beating field weighing operations personnel's technical ability and mainly sees smoothing Level height, therefore for distortion, the excessive part of buckling deformation, to operator's skill set requirements Higher, smoothing process hammer trace or dregs are easily pressed against and are hindered material surface, even destroy the mechanicalness of material Can, have a strong impact on product service life.

Summary of the invention

Present invention aims to the deficiencies in the prior art, it is provided that a kind of many reinforcements of plate system Sheet metal part rubber pocket manufacturing process and shaping dies.In order to achieve the above object, the present invention adopts Use following technical scheme:

A kind of plate system many reinforcements sheet metal part rubber pocket manufacturing process, containing many reinforcements panel beating The expansion woollen of part, it is characterised in that 1) there is a shaping dies, this shaping dies bag Containing die matrix and limitting casing, described die matrix is the block shape similar to sheet metal component shape Shape, die matrix upper surface is the forming face corresponding with many reinforcements sheet metal component, has in forming face The grooving of reinforcement, the surrounding of forming face is annular technique edges, is provided with location on technique edges Hole, described limitting casing is the loop configuration mated with die matrix technique edges, and limitting casing is provided with The connecting hole corresponding with hole, location；2) described limitting casing is placed on the technique edges of die matrix, The connecting hole of limitting casing is connected fixing with the hole, location of die matrix by alignment pin；3) will Launching woollen to be placed in the forming face of die matrix, limitting casing limits the foreign steamer launching woollen Wide；4) by step 3) described in shaping dies with launch woollen be placed into rubber pocket pressure work Station is pressurizeed, and makes expansion woollen be configured to many reinforcements sheet metal part；5) finally pull out spacing Alignment pin between frame and die matrix, removes limitting casing, to many reinforcements on die matrix Sheet metal part carries out repairing.

This technological invention provides the benefit that: 1) the method uses and launches woollen profile location, no Only save shaping rear cutout to chop off the ears sheet and the work of cut place deburring, and can partly overcome pin Limit material inwardly to supplement, cause distortion, warpage, problems of crack, be greatly lowered behaviour Make personnel's skill set requirements, improve surface quality of workpieces, shorten the process-cycle.2) mould structure Simply, processing ease, decrease workman's workload, shorten the process-cycle, reduce operator Member's skill set requirements.3) being greatly reduced of trim amount, decreases and hammers trace or dregs in dressing process into shape Pressing against and hinder material surface, the phenomenon of the mechanical performance even destroying material occurs, and improves part Surface quality.

Below in conjunction with embodiment accompanying drawing, the present invention is described in further detail.

Accompanying drawing explanation

Fig. 1 is the signal of plate system many reinforcements sheet metal part rubber pocket forming die structure

Fig. 2 is the signal of plate system many reinforcements sheet metal part rubber pocket manufacturing process

Fig. 3 is the signal of plate system many reinforcements sheet metal part rubber pocket manufacturing process cross section

In figure numbering explanation: 1 die matrix, 2 forming faces, 3 technique edges, 4 location holes, 5 Grooving, 6 limitting casings, 7 connecting holes, 8 alignment pins, 9 sheet metal parts

Detailed description of the invention

Seeing accompanying drawing, concrete steps are implemented as follows:

The manufacturing process of plate system many reinforcements sheet metal part that embodiment provides and shaping dies are such as Shown in figure.Shaping dies comprises die matrix 1 and limitting casing 6, and described die matrix is and metal plate The blob-like shapes that metal parts shape is similar, die matrix 1 upper surface is and many reinforcements panel beating zero The forming face 2 of part 9 correspondence, has the grooving 5 of reinforcement in forming face 2, forming face 2 Being around annular technique edges 3, be provided with hole 4, location on technique edges 3, described limitting casing 6 is The loop configuration mated with die matrix technique edges 3, limitting casing 6 is provided with to position hole 4 right The connecting hole 7 answered.

During use, described limitting casing 6 is placed on the technique edges 3 of die matrix 1, by fixed The connecting hole 7 of limitting casing is connected fixing with the hole, location 4 of die matrix by position pin 8；To be used for The woollen that launches shaping many reinforcements sheet metal part is placed in the forming face 2 of die matrix, limit Position frame 6 limits the outline launching woollen；The shaping dies assembled is placed with launching woollen Pressurize on rubber pocket pressure duty platform, make expansion woollen be configured to many reinforcements sheet metal part 9, In forming process, material uniformly flows from reinforcement surrounding all directions to grooving, makes metal plate Metal parts keeps smooth substantially；Finally pull out the alignment pin 8 between limitting casing and die matrix, Being separated with die matrix 1 by limitting casing 6, on die matrix, sheet metal part 9 carries out finishing i.e. Can.

Require supplementation with explanation 2 points: one is to launching the control of woollen overall dimensions, it is desirable to ratio is spacing Frame 6 is smaller；Two be the application only as a example by parallel reinforcement sheet metal part rectangle, its Its sheet metal part takes similar approach should belong to the application protection domain.
