Description
Technical field
The present invention relates to sheet metal processing fields, and in particular to a kind of panel beating method of flexibility upper mold is suitable for processing
Progressive thickness and part with step structure.
Background technology
To mitigate weight, in aviation part, there are a large amount of step structures, it is possible to understand that " to be spelled by different-thickness blank
Connect " constituent part.The manufacture of part step has two methods of mechanical processing, chemistry milling, and wherein chemistry milling is due to tank liquor pair
Environmental pollution is serious, and to part fatigue behaviour decrease to some degree, is the technology it is not recommended that using in aeronautical manufacture.
Such part main problem is first processing step structure or post-processing step structure, in the ban processing step structure
When, current process, which is focused primarily upon, is filled and led up the step of blank using metal or nonmetallic bedding and padding, afterwards using traditional roll bending, pressure
The techniques such as curved are formed, but design, the processing etc. of bedding and padding are required for longer cycle, and stress is difficult in roots Level forming
Control, while the part of progressive thickness cannot be processed.When post-processing step, technological process adds for sheet metal forming technology
Mirror image milling, the technological process is since mirror image milling technical maturity is poor, springs back serious, specific implementation in step processing
It is middle that there are the process-cycle is long, the shape degree requirement of part is high after roll bending, part is persistently clamped difficult, element precision and is difficult to ensure
The problems such as.
Invention content
In order to solve the above-mentioned problems in the prior art, the present invention provides a kind of panel beating side of flexible upper mold
Method is suitable for processing progressive thickness and the part with step structure.
Panel beating method according to the present invention, processing mold include upper mold, lower mold and rubber pocket, the rubber pocket
The lower surface sealed around for being connected to the upper mold, which is characterized in that the panel beating method includes step：
Blank is lain in a horizontal plane in the upper surface of the lower mold；
Pressing plate is placed on to the periphery of the blank, and apply pressure-pad-force with by the blank holding in the pressing plate and institute
It states between lower mold；
The upper mold is moved down to the position close to the blank so that the upper mold, the pressing plate and institute
It states and forms enclosure space between lower mold；
By hydraulic pump, into the rubber pocket below the upper mold, pumping liquid, realization rubber intraluminal pressure increase, with
Press molding is carried out to the blank；
Liquid is completely drawn out by hydraulic pump；
Unload pressing plate；
Take out part.
Wherein, the upper mold is equipped with fluid passage, and the hydraulic pump is by the fluid passage into the rubber pocket
It is pumped into or extracts out liquid.
Wherein, the liquid is water or oil.
Compared with prior art, the present invention has the following advantages：
1, method using the present invention can process progressive thickness and the part with step structure.
2, the present invention is pressure processing method, can get that surface quality is more excellent, the higher part of precision.
3, the present invention realizes sheet metal forming technology by flexible bedding and padding, and avoiding needs matching bedding and padding could be into prior art
It the problem of row processing, can effectively save manufacturing cost.
4, method of the invention can process the parts such as plank, proximate matter.
Description of the drawings
The other feature and advantage of the present invention will be more preferable by the preferred embodiment being described in detail below in conjunction with attached drawing
Ground understanding, wherein：
Fig. 1 is the structural schematic diagram for the device for implementing panel beating method according to the present invention.
Specific implementation mode
It, will be with reference to the appended attached drawing for constituting a present invention part in the specific descriptions of following preferred embodiment.Institute
Attached attached drawing, which has been illustrated by way of example, can realize specific embodiment.Exemplary embodiment is not intended to
Limit all embodiments according to the present invention.It is appreciated that without departing from the scope of the present invention, can utilize other
Embodiment can also carry out structural or logicality modification.
Fig. 1 shows the structural schematic diagram for the device for implementing panel beating method according to the present invention.The device includes upper
Mold 1, lower mold 2, rubber pocket 3, blank 4, pressing plate 5 and hydraulic pump 6.Its 5 surrounding of center platen has, cross section and lower mold
2 just match, and thus pressing plate 5 can constitute enclosure space with upper mold 1, lower mold 2, realize 3 pressure rise of rubber pocket.
Specifically, panel beating method according to the present invention includes mainly step：
Blank is placed, is horizontally arranged blank 4 in the upper surface of lower mold 2 first；
Apply pressure-pad-force so that pressing plate 5 is closed with lower mold 2.4 surrounding of blank deforms at this time, and clossing pressure needs
Consider the parameters such as the thickness difference, thickness, plastic deformation force of blank 4；
1 downlink of upper mold stops to the position close to blank 4, and the forcing press of connection upper mold 1 need to provide enough supports
Power so that in formation in rubber pocket 3 under the action of pressure, upper mold 1 does not move backward；
6 pumping liquid of hydraulic pump (can be water, oil or other solution) leads to until pressure is met the requirements in rubber pocket 3
Pressure in raising rubber pocket 3 is crossed, to carry out press molding to blank 4；
Hydraulic pump 6 inverts, and liquid is completely drawn out；
Pressing plate 5 unloads；
Take out formation of parts.
Hydraulic pump 6 in the present invention need to have suction, put two kinds of functions, can control total amount of liquid, pressure in rubber pocket 3.
In the embodiment shown in fig. 1, upper mold 1 is equipped with fluid passage 11, is pumped into or extracts out into rubber pocket 3 by fluid passage 11
Liquid.
