Detailed description of the invention
As shown in Figures 1 to 5, the present embodiment provides a kind of warm shaping of metal plate device based on electromagnetic field of high frequency of inducting,
Workbench 2 offers the punching press mouth 21 of up/down perforation, and bracing frame includes being positioned at the mounting plate 9 on the upside of workbench 2, is positioned at work
Bottom plate 16 on the downside of platform 2 and the connecting rod 6 being slidably connected with workbench 2, connecting rod 6 is two, two connecting rods 6 points
Not being positioned at the both sides of punching press mouth 21, connecting rod 6 is arranged with spring 4, one end of spring 4 is stuck in workbench 2 and mounting plate 9
Between, spring 4 plays the effect supporting whole bracing frame.The two ends of connecting rod 6 are respectively through nut 5 assembly connection mounting plate 9
With bottom plate 16, punch forming assembly include being positioned at be flexibly connected directly over punching press mouth 21 and with mounting plate 9 punch 8, be positioned at
Punching press mouth 21 edge and with the guided mode plate 12 that workbench 2 is flexibly connected, be positioned at above guided mode plate 12 and movable with guided mode plate 12
The blank holder 10 connected, mounting plate 9 offers connector, and punch 8 is fixedly connected with the baffle plate that can engage with connector, with
Punch 8 is made to be flexibly connected mounting plate 9.Coolant 7 it is filled with in punch 8.High-frequency electromagnetic field generator is just being positioned at punching press mouth 21
Lower section and with bottom plate 16 assembly connection, high-frequency electromagnetic field generator includes that high frequency coil with bottom plate 16 assembly connection accommodates
Frame 13 accommodates the fixing high frequency coil bracing frame 15 being connected of frame 13 and is assemblied on high frequency coil bracing frame 15 with high frequency coil
High frequency coil 14, wherein, high frequency coil bracing frame 15 be positioned at high frequency coil accommodate frame 13 inside, high frequency coil bracing frame
15 include longitudinal support 151 and the multiple lateral frames 152 that are connected fixing with longitudinal support 151, and longitudinal support 151 accommodates with high frequency coil
Frame 13 is fixing to be connected, and high frequency coil bracing frame 15 is multiple, lateral frame mutually close on two adjacent high frequency coil bracing frames 15
152 are staggered.In the present embodiment, on workbench 2, the side of sheet metal 11 is provided with temperature sensor 3, and temperature passes
Sensor 3 can contact with sheet metal 11.
The warm shaping of metal plate device based on electromagnetic field of high frequency of inducting of the present embodiment, its work process is as follows: proceed by
Before the press work of sheet metal 11, adjust guided mode plate 12 and the installation site of blank holder 10 according to the geomery of drip molding.
Placing sheet metal 11 between guided mode plate 12 and blank holder 10, blank holder 10 is close to the upper surface of sheet metal 11.Open
Open high frequency electric source 1, high frequency coil 14 be passed through high frequency alternating current, high frequency coil 14 produce one uneven, change rapidly
High frequency magnetic field.Sheet metal 11 is in the middle of this high frequency magnetic field, due to induction effect, makes sheet metal 11 surface collect
Skin effect, has eddy current and produces, the magnetic field that the generation of this eddy current is in opposite direction with high frequency coil 14, thus sheet metal 11 and height
Frequently producing repulsive force between coil 14, sheet metal 11 is internal because eddy current effect produces heat simultaneously.According to the needs shaped,
The size of Reasonable adjustment high frequency electric source 1, frequency and the locus of high frequency coil 14, and then high frequency coil 14 He can be changed
The size and Orientation of the repulsive force produced between sheet metal 11, therefore, when punch 8 is in the middle of descending process, can be metal
The active force that sheet material 11 is subject to sees the die in conventional ones technique as.Temperature sensor 3 monitors the temperature of sheet metal 11
Change, when the temperature of sheet metal 11 reaches desired temperature, punch 8 moves down.When punch 8 goes downwards to and sheet metal
During 11 contact, the prominent baffle plate of punch 8 both sides is pressed on the edge of mounting plate 9 connector, and then punch 8 drives bracing frame
Move down.Now, along with punch 8 continue move down, spring 4 is compressed, and spring 4 is increasing to the elastic force of punch 8.
On the basis of high frequency coil 14 is to the repulsive force of punch 8, the elastic force that punch 8 is gradually increased by additional springs 4, make metallic plate
The active force that material 11 deforms suffered by position is uniform and stable.Sheet metal 11, in deformation folding process, remains and high frequency
The fixing distance of coil 14, the temperature field of sheet metal 11 is the most uniform and stable.After sheet metal 11 shapes, disconnect height
Frequency power 1, punch 8 is up under the effect of spring 4, and punch 8 separates with sheet metal 11, takes out drip molding, completes this
Secondary stamping processing, each several part of warm shaping of metal plate device based on electromagnetic field of high frequency of inducting recovers to initial position,
The most stamping on carrying out add man-hour, only need to place sheet metal 11, repeat above-mentioned process operation.
The warm shaping of metal plate device based on electromagnetic field of high frequency of inducting of the present embodiment, eliminates the making of die, makes mould
Expense reduces, and reduces the cost of stamping of sheet metal 11, simplifies sheet metal 11 Sheet Metal Forming Technology, is not produced by stamping parts and criticize
Quantitative limitation, and improve the ram efficiency of sheet metal 11.Sheet metal 11 uniform force and temperature field are the most uniform and stable, from
And improve surface quality and the precision of drip molding, by the power of all directions bottom sheet metal 11, there is good patch mould.
Due to the warm shaping of metal plate device based on electromagnetic field of high frequency of inducting in the present embodiment, sheet metal 11 therein is internal,
The sidewall of blank holder 10 and guided mode plate 12 all can produce rapidly heat because of eddy current effect, and then can add sheet metal 11
Heat, therefore can give full play to the forming property of the sheet metal 11 of high intensity and plasticity difference, improve the shaping of sheet metal 11
The limit, reduces plastic force, when the sheet material that sheet metal 11 be high intensity, difficult shaping, stamping after stamping parts quality excellent
Good.In punch 8, the coolant 7 of circulation can carry out cooling down sizing to the part that sheet metal 11 is formed, makes drip molding
Intensity, precision are high, effectively reduce resilience, the problem such as wrinkling, are particularly suitable for producing complex-shaped high intensity or plasticity is poor
The punch process of sheet metal 11.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the art
Change that technical staff is made in the essential scope of the present invention, retrofit, add or replace, also should belong to the protection of the present invention
Scope.
