Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 2 the schematic diagram of the utility model punching and edge-cutting mould.Punching and edge-cutting mould includes punch assemblies, recessed
Membrane module, punch assemblies include punch-pin bottom plate, and multiple body of punch structures, above-mentioned multiple body of punch knots are fixed with punch-pin bottom plate
Structure interval setpoint distance arrangement, cavity plate component include cavity plate bottom plate, are fixed with cavity plate bottom plate and above-mentioned multiple body of punch knots
Multiple die body structures that structure coordinates, punch assemblies complete punching and edge-cutting operation with cavity plate component move toward one another.Such scheme is adopted
It is instead of with multiple individually body of punch structures with the mode of corresponding multiple die body respective outer side edges in existing scheme using company
The mode (as shown in Figure 1) that integral multiple punch-pin coordinate with cavity plate, according to product contraction distortion feature, individually positioning is each
The position of mould, effectively overcome product incised notch excessively caused by deformation produces the accumulation of error and fall into, machining accuracy greatly improved, have
Effect reduces the percent defective of processing, has saved production cost, has improved production efficiency.On the basis of such scheme, this programme
The convenience and efficiency of punch-pin positioning are taken into account, 2 body of punch structures are preferably fixed with punch-pin bottom plate, are consolidated on cavity plate bottom plate
Fixed 2 die body structures being provided with above-mentioned 2 body of punch respective outer side edges.Before production, the interstructural position of body of punch is first positioned
Relation, the position of cavity plate is set further according to this position relationship, finally completes punching and edge-cutting operation.
On the basis of such scheme, this programme also discloses further Curve guide impeller, specific as follows.In order to improve mould
Have the quality of processing, extend the mold use life-span, this programme is provided with the trimming of evagination on the die orifice edge of die body structure
Ring structure, the wedge shaped structure of axial cross section of trimming ring structure, as shown in Fig. 2 the marginal texture of this protrusion effectively increases
The efficiency of processing.Safeguarded for the ease of the handling of equipment, take into account the overall stability of component, the body of punch structure of this programme with it is convex
