Description
Technical field
The present invention relates to car panel die field, especially relate to a kind of rotary material pressing core mechanism and use one group of stamping die of automotive covering part and the process for stamping of this mechanism.
Background technology
In recent years, along with the development of process industry, pursuing product quality and saving manufacturing cost becomes the two large problems that enterprise is rather concerned about.Because the surface modeling of vehicle body is complicated, in He Bian orientation, hole above, there is many difference, in some exist negative angle and the less shaped region of area, sometimes need to arrange special binder technique, how to design that material pressing device could not only meet binder requirement but also can make mould structure optimization is the difficult problem in current design always.
When design vehicle diel, for the drip molding that needs side direction binder, be all generally to adopt self-control combination Wedge mechanism to realize at present, structure as shown in Figure of description 1.The operation principle of the Wedge mechanism of the type is as follows: side pressure core and forming-tool piece are all arranged on the first slide block, by drive block and the pressure source being arranged on the first slide block, power is provided and is utilized guide plate to lead, and realizes lateral pressing.Facts have proved, the type Wedge mechanism can meet the requirement of most of side direction binder, but there is negative angle and the less situation of shaped region for some, result of use is limited.In order to consider guiding and the pressure source of side pressure core, arrange, the first slide block volume of designing is tens times that real work needs, thereby caused very large waste of material, and increased structure complexity and pincers worker debugging difficulty, binder effect can not reach desirable requirement.Meanwhile, such mechanism relates to that content is more thereby manufacturing process is complicated, not only not attractive in appearance in the larger mould of profile drop, also extremely affects smooth pickup.
Summary of the invention
Technical problem to be solved by this invention be for problems of the prior art provide a kind of side be shaped little pressure core, with the be shaped mould of little pressure core of this side, its objective is and can meet special binder requirement, can reduce again wedge volume, simplify mould structure, facilitate pincers worker to operate and reduce the feeding pressure mechanism of manufacturing cost.
