Description
Technical field
The application is related to a kind of metal plate semicanal forming technique in aircraft manufacturing field, specifically a kind of plate semicanal flexibility punching
Compression mould and application method, the thin plate semicanal that is particularly suitable for use in are stamping.
Background technology
The main manufacturing process of current plate sheeting semicanal is bent pressure, falls pressure, drawing, and it is inclined, broken to press that it shapes major defect
The problems such as splitting, wrinkle.Conventional stamping method shortcoming has several aspects, and one is that, because most semicanals are in irregular shape, shaping stress is not
, the inclined phenomenon of pressure is easily produced；Two be that forming process plate central region is in hanging free deformation, it is impossible to suppresses deformation
Inequality produces Instability wrinkling problem；Three be to lack material problem to overcome woollen pressure that increased in size compensation can only be taken to shape partially, is led
Cause put while, receive while difficulty increase severely；Four be that mould needs to process the complicated convex-type face that matches with part surfaces externally and internally and recessed
Swaged face, mould processing capacity is big, and fit precision requires high.Above reason causes new product development success rate relatively low, causes various
Diel repeatedly die trial, repair a die, cause great amount of cost and time to waste.
The content of the invention
The purpose of the application is there is provided a kind of flexible diel of plate semicanal and to use in view of the shortcomings of the prior art
Method；The diel continuingly acts on plate using the rigid convex face of upper mould with lower mould inner high voltage flexible media, suppresses plate
Central region wrinkles, while producing enough frictional force alleviates the inclined problem of pressure, woollen reduction semicanal shaping is difficult needed for can reducing shaping
Degree.
A kind of flexible process for stamping of plate semicanal, contains the upper mould of rigidity and flexible lower mould, it is characterised in that：1) it is firm described in
Property on have the convex face matched with the pipe internal surface of plate system half below mould, the matrix of the flexible lower mould is a square rigidity
Hold basket and rigid cover plate, pass through the respectively connection one of the bolt and nut with spring respectively on the inside of the left and right sides wallboard for rigidly holding frame
The rigid panel of activity, the top of two rigid panels is connected by elastic covering, and the rigid panel holds another the two of frame with rigidity
In the middle part of individual side wall and elastic covering constitutes the flexible cavity of a closing, the middle part of described rigid cover plate be provided with rigidity
The profile hole of mould convex facial contour matching, rigid cover plate is pressed in the top that rigidity holds frame by fastener cover；2) declining upper mould makes
Convex face is completely embedded into the flexible cavity of lower mould by the profile hole of rigid cover plate, the screw rod spiral shell of the rigid panel of regulation connection
Mother, by spring compression to appropriate location；3) the flexible cavity injection resisting medium of mould makes it be full of flexible cavity downwards；4) rise
Upper mould, adjusting screw rod nut pull-off spring is to appropriate location again, and spring promotes rigid panel slid inward, makes lower mould flexible empty
Intracavitary keeps certain initial pressure；5) plate to be formed is placed between upper mould and lower mould, mould is embedded in convex face in decline
In flexible cavity, the compression drag of spring promotes resisting medium to produce the completion plate semicanal punching press of pliable pressure continuous action plate
Shaping.
The beneficial effects of the invention are as follows：1) the application is stamping only needs the profile hole of processing mold convex face and lower mould,
Making mold workload is greatly reduced, and fit precision problem is manufactured in the absence of upper mould convex face and lower mould matrix face.2) originally
Application upper mould and matching cover plate profile hole needed for by changing shaping, it is stamping to meet variously-shaped semicanal, no
Limited by half tube shape, it is applied widely.3) the application is acted on and panel surface by high pressure resisting medium, is rushed with conventional rigid
Pressing mold damages small, product quality is high compared to being more uniformly stressed to panel surface.4) produced in the middle part of the application punching course plate
Frictional force can alleviate woollen and press inclined problem, woollen needed for shaping be advantageously reduced, while middle part corrugation area excess stock is arranged
Remove and add to weakened section, greatly alleviate weakened section cracking.
Accompanying drawing is described in further detail to the application with reference to embodiments：

Embodiment
Referring to accompanying drawing, plate semicanal flexibility diel disclosed in embodiment is described containing the upper mould of rigidity and flexible lower mould
Rigidity on the lower section of mould 9 have a convex face 10 matched with the pipe internal surface of plate system half, the matrix of the flexible lower mould is a side
The rigidity of shape holds basket 1 and rigid cover plate 2, and the screw rod spiral shell with spring 3 is passed through respectively on the inside of the left and right sides wallboard for rigidly holding frame 1
Mother 4 respectively connects a movable rigid panel 5, and the top of two rigid panels 5 is connected by elastic covering 6, the rigid panel 5
Hold with rigidity in the middle part of the another two side wall of frame 1 and elastic covering 6 constitutes the flexible cavity 7 of a closing, described rigid cap
The middle part of plate 2 is provided with the profile hole 8 with the upper outline of mould convex face 10 of rigidity, and rigid cover plate 2 is pressed in just by fastener cover
Property hold frame 1 top.One is respectively equipped with close to bottom with top connect flexibility in the middle part of the front and rear sides side wall for rigidly holding basket 1
The material feeding through hole 14 of cavity 7 and a discharge through hole 15.
Using flexible forming method of the above-mentioned diel to plate semicanal, its operating procedure is as follows：
1) declining upper mould makes convex face 10 be completely embedded into by the profile hole 8 of rigid cover plate 2 in the flexible cavity 7 of lower mould,
Spring 3 is pressed to appropriate location by adjusting screw rod nut 4.2) while opening material feeding through hole 14 and discharge through hole 15, downward mould
The flexible injection of cavity 7 resisting medium 11 makes it be full of flexible cavity 7.3) material feeding through hole 14 and discharge through hole 15 are simultaneously closed off, on
Mould is gone up, the pull-off spring 3 of adjusting screw rod nut 4 arrives appropriate location, and spring 3 promotes the rigid slid inward of panel 5, makes lower mould flexible
Certain initial pressure is kept in cavity 7.4) plate 16 to be formed is placed between upper mould and lower mould, mould makes convex face in decline
In the flexible cavity 7 of 10 insertions, the compression drag 12 of spring 3 promotes the generation continuous action plate of pliable pressure 13 of resisting medium 11 complete
It is stamping into plate semicanal.
Require supplementation with explanation three aspects, one be illustrations and specification with plate threeway semicanal for example, this
Application is suitably adapted for the flexible punching press such as the bend pipe of plate system half, half flat tube by changing the matching upper mould convex face 10 of rigid cover plate 2
Shaping, therefore other parts take the similar stamping technology for applying reverse pliable pressure to belong to this specification protection domain.Two
Be rigidity hold the front and rear sides side wall of basket 1 on material feeding through hole 14 and discharge through hole 15 respectively close to bottom and top, it is therefore an objective to be
Injection resisting medium 11 discharges the gas in flexible cavity 7, makes the smoothly flexible cavity 7 of injection of resisting medium 11.Three be rigidity
The height of panel 5 is slightly less than rigidity and holds the depth capacity of basket 1, it is therefore an objective to ensure that rigid panel 5 is smoothly slided in rigidly appearance basket 1,
Avoid rigid panel 5 and the lower surface friction of rigid cover plate 2.
