Low maintaining cost.First drawing operation mould stress is big, and core rod abrasion is big, can be by last one procedure flange
Making up, requirement of the same trimming and piercing die to core rod forming face is nor very high for shaping, as long as therefore ensureing last one procedure
Forming face precision ensure that the precision of product.When producing in enormous quantities, reduce to core rod crudy and quantity
Require.In mould, nitrogen cylinder has obtained substantial amounts of application, reduces die size.Nitrogen cylinder is closed along deformation of products maximum position
Reason distribution so that mould uniform force, improves the accuracy of form and position, improves the qualification rate of product morpheme, extends mould and uses
Life-span；When nitrogen cylinder is divided into two groups, one group instead of post rod mechanism, reduce the complexity of mould, while during feeding so that
On the part that machines together conveniently can smoothly be placed on this station, the reasonable disposition of another group of nitrogen cylinder so that
The punching stroke of part has obtained very big convenient, it is to avoid the part punching that stroke deficiency is caused is not in place, more avoids stroke
The excessive part for causing or burn failure, in addition so that several process moulds can be in any combination, it is to avoid mold height differs
Difficulty and interfere with each other that the punching stroke that cause is caused is adjusted, have very big degree of freedom space on stroke is arranged, and greatly reduce
Mold height adjustment time.Upper mould core is divided to two pieces of designs, is easy to the processing and replacing of core rod, and insert is by multiple part groups
Close, be easy to the fine setting of mould, reduce the fraction defectives such as marginal portion corrugation, drawing crack, improve conforming product rate.Mould core and
The TD process of insert improves the qualification rate of product, while substantially prolongs the life-span of mould.
