Description
Technical field
The utility model relates to mould applications, more particularly to a kind of cupping tool.
Background technique
Now, auto industry develops rapidly, and the requirement to process of sheet forming technology is higher and higher.And process of sheet forming
The failure of two kinds of fundamental types in processing：Corrugation and rupture, leverage the quality of Forming Workpiece.In drawing process process
In, scientifically distribute pressure-pad-force a possibility that capable of effectively reducing failure on blank holder, i.e., the pressure-pad-force of blank holder straight flange compared with
Greatly, and should change with the process of processing, and the pressure-pad-force of round edge should be smaller.But conventional blank holder in the prior art
To workpiece apply pressure-pad-force be it is average, cannot scientifically press area distribution pressure-pad-force.Existing improved technology divides blank holder
Block simultaneously configures corresponding hydraulic stem for each flanging block to adjust and apply pressure-pad-force thereon and optimize punching course, improves workpiece
Quality.Although this method can obtain extraordinary effect, structure is complicated, higher cost, can not be widely applied.
In conclusion therefore, how providing one kind can easily realize that the cupping tool of zonal control pressure-pad-force becomes
The technical problem urgently released.
Utility model content
The purpose of this utility model is to provide a kind of cupping tools, with overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
The utility model embodiment discloses a kind of cupping tool, including upper die and lower die and flange fixing installation, the flanging dress
Set including blank holder, the blank holder by straight flange flanging area and round edge flanging section every being formed by fixedly connecting, the straight flange pressure
The top in border area is connect by elastic component with the upper mold, and round edge flanging area is compressed by holding down assembly, the compression
Component includes Z-type gripping block, bolt and adjusting nut, and one end of the Z-type gripping block is fixedly arranged on the lower die by fastener
Top, the bolt is placed through the other end of the adjusting nut and the Z-type gripping block above the Z-type gripping block
And workpiece pressing.
One of as a preferred embodiment of the present invention, the blank holder is the square structure with fillet, the flanging
Circle is composed of a fixed connection by four straight flange flanging blocks and four round edge flanging block gaps.
One of as a preferred embodiment of the present invention, the elastic component is spring or rubber block.
One of as a preferred embodiment of the present invention, the blank holder bottom is equipped with buffer layer.
One of as a preferred embodiment of the present invention, the buffer-layer surface is equipped with multiple hemispherical projections.
Compared with prior art, the advantages of the utility model at least that：
A kind of cupping tool provided by the utility model at work, what the round edge flanging block of blank holder applied workpiece
Pressure-pad-force is constant by acting on clamping element offer thereon；And the pressure-pad-force that straight flange flanging block applies workpiece is squeezed by upper mold
The pressure of pressing spring effect thereon provides, and with the drawing of workpiece, the compressed degree of spring is continuously improved, and acts on straight flange
Power on flanging block is increasing until manufacturing procedure is completed.The utility model realizes the zonal control to pressure-pad-force, can
Preferably processing effect is obtained, workpiece quality is improved；The utility model also has structurally simple, economical property good, easy to operate easy
Capable advantage.
Detailed description of the invention
