Positioned at the both sides of punching press mouth 21, spring 4 is arranged with connecting rod 6, one end of spring 4 is stuck between workbench 2 and mounting plate 9,
Spring 4 plays a part of the whole support frame of support.The both ends of connecting rod 6 are respectively through the assembly connection mounting plate 9 of nut 5 and bottom plate
16, punch-pin 8 that punch-pin forming assembly includes being flexibly connected directly over punching press mouth 21 and with mounting plate 9, positioned at punching press mouth 21
Edge and with guided mode plate 12 that workbench 2 is flexibly connected, the flanging being flexibly connected above guided mode plate 12 and with guided mode plate 12
Circle 10, mounting plate 9 offers connector, and the baffle plate that can be engaged with connector is fixedly connected with punch-pin 8, so that the activity of punch-pin 8
Connect mounting plate 9.Coolant 7 is filled with punch-pin 8.High-frequency electromagnetic field generator is located at immediately below punching press mouth 21 and and bottom plate
16 assembly connections, high-frequency electromagnetic field generator include accommodating frame 13 and high-frequency line with the high frequency coil of the assembly connection of bottom plate 16
Circle accommodates the high frequency coil support frame 15 that frame 13 is fixedly connected and the high frequency coil 14 being assemblied on high frequency coil support frame 15, its
In, high frequency coil support frame 15 is located at the inside that high frequency coil accommodates frame 13, and high frequency coil support frame 15 includes the He of longitudinal support 151
The multiple lateral frames 152 being fixedly connected with longitudinal support 151, longitudinal support 151 accommodate frame 13 with high frequency coil and are fixedly connected, high-frequency line
Support frame 15 is enclosed to be multiple, mutually close lateral frame 152 is staggered on two adjacent high frequency coil support frames 15.The present embodiment
In, the side of sheet metal 11 is provided with temperature sensor 3 on workbench 2, and temperature sensor 3 can connect with sheet metal 11
Touch.
The warm shaping of metal plate device based on electromagnetic field of high frequency of inducting of the present embodiment, its course of work are as follows：Open
Before beginning carries out the press work of sheet metal 11, the peace of guided mode plate 12 and blank holder 10 is adjusted according to the geomery of drip molding
Holding position.Sheet metal 11 is placed between guided mode plate 12 and blank holder 10, blank holder 10 is close to the upper table of sheet metal 11
Face.High frequency electric source 1 is opened, high frequency alternating current is passed through in high frequency coil 14, high frequency coil 14 produces a uneven, rapid change
The high frequency magnetic field of change.Sheet metal 11 is among this high frequency magnetic field, due to induction effect, collects the surface of sheet metal 11
Skin effect, have vortex and produce, the vortex produces and the magnetic field in opposite direction of high frequency coil 14, so as to sheet metal 11 and high frequency
Repulsive force is produced between coil 14, while the inside of sheet metal 11 is because eddy current effect produces heat.According to the needs of shaping, close
The locus of the size for adjusting high frequency electric source 1, frequency and high frequency coil 14 is managed, and then high frequency coil 14 and metal can be changed
The size and Orientation of caused repulsive force between sheet material 11, therefore, can be sheet metal when punch-pin 8 is among descending process
11 active forces being subject to see the cavity plate in conventional ones technique as.Temperature sensor 3 monitors the temperature change of sheet metal 11,
When the temperature of sheet metal 11 reaches desired temperature, punch-pin 8 moves down.Contacted when punch-pin 8 is gone downwards to sheet metal 11
When, the baffle plate of the protrusion of the both sides of punch-pin 8 is pressed on the edge of the connector of mounting plate 9, and then punch-pin 8 drives support frame to moving down
It is dynamic.Now, continue to move down with punch-pin 8, spring 4 is compressed, and spring 4 is increasing to the elastic force of punch-pin 8.In high frequency coil
On the basis of the repulsive force of 14 pairs of punch-pin 8, elastic force that additional springs 4 gradually increase punch-pin 8 makes the deformation position of sheet metal 11
Suffered active force is uniform and stable.Sheet metal 11 remains what is fixed with high frequency coil 14 in folding process is deformed
Distance, the temperature field of sheet metal 11 are also uniform and stable.After sheet metal 11 shapes, high frequency electric source 1, punch-pin 8 are disconnected
Up in the presence of spring 4, punch-pin 8 separates with sheet metal 11, takes out drip molding, completes this stamping processing, base
Recover in each several part of the warm shaping of metal plate device for electromagnetic field of high frequency of inducting to initial position, carrying out punching press next time
During forming, sheet metal 11 need to be only placed, repeats 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 cavity plate,
Die cost is reduced, the cost of stamping of sheet metal 11 is reduced, simplifies the Sheet Metal Forming Technology of sheet metal 11, do not given birth to by stamping parts
The limitation of batch is produced, and improves the ram efficiency of sheet metal 11.The uniform force of sheet metal 11 and temperature field is also uniform and stable,
So as to improve the surface quality of drip molding and precision, the bottom of sheet metal 11 is had good patch by the power of all directions
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 therein
Inside 11, the side wall of blank holder 10 and guided mode plate 12 can produce heat rapidly because of eddy current effect, and then can be to sheet metal
11 are heated, therefore can give full play to the forming property of the sheet metal 11 of high intensity and plasticity difference, improve sheet metal
11 forming limit, reduce plastic force, sheet metal 11 be high intensity, difficult shaping sheet material when, it is stamping after punching press
Part is best in quality.The coolant 7 circulated in punch-pin 8 understands the part formed to sheet metal 11 and carries out cooling down sizing, makes
The intensity of drip molding, precision are high, the problems such as effectively reducing resilience, corrugation, be particularly suitable for producing complex-shaped high intensity or
The punch process of the sheet metal 11 of person's plasticity difference.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made in the essential scope of the present invention, it should also belong to the present invention's
Protection domain.
