Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
A kind of hardware diel of the present invention, for processing the part as shown in accompanying drawing 1,2.Hardware processing mold of the present invention, as shown in accompanying drawing 3,4, comprises die shank (1), upper bolster (2), die shoe (3), rolling independent guide device (4), punch retainer (5), punch (6), die block (7), die; Described die shank (1) is fixing along the through upper bolster of axis (2) of upper bolster (2), and half part exceeds the upper surface of upper bolster (2); Be connected by rolling independent guide device (4) between described upper bolster (2) with die shoe (3); The lower end of described upper bolster (2) is installed with punch retainer (5) by securing member; Described punch retainer (5) be axially fixedly connected with punch (6); The upper end of described die shoe (3) is installed with die block (7) by securing member; Described die block is arranged with die in (7) vertically; Described die is Split type structure, comprises location-plate (8) and concave template (9); Described location-plate (8) is positioned at concave template (9) upside; Split type die has following advantage: one, reduce the difficulty of processing of die inner surface, and make die inner surface precision high, this can make flow of material dynamic resistance in punching course little, and punching press is smooth; The corner of two, solid die being placed part has larger stress to concentrate, and is the immediate cause causing die easy to crack, and two-piece unit formula die does not exist stress and concentrates, and die cracking phenomena is able to obvious improvement.The lower end of described lower bolster (3) to be fixedly connected sequentially upper padding plate (11), cushion pad (12) and lower bolster (13) by securing member (10); The axial centre of described die shoe (3) is also provided with discharging device.Described discharging device comprises material returned bar (14), material returned support (15) and spring (16), and described spring (16) is set in material returned bar (14) outward; Described material returned support (15) is set in material returned bar (14) outward also can along the axially lower slider of material returned bar (14); The lower end of material returned support (15) is connected with the upper end of spring (16), and the first half of material returned support (15) is positioned at concave template (9); Described material returned bar (14) is run through die shoe (3) and upper padding plate (11) vertically successively and is fixed on upper padding plate (11).
The operation principle of hardware processing mold of the present invention is, first raw material are put into the centre bore of concave template location-plate (8), its raw material are the kidney ellipsoid sheet that preprocessing is good, then die shank (1), upper bolster (2), punch retainer (5) and punch (6) action downwards, undertaken leading and being expressed to extreme position by rolling independent guide device (4), the cavity relying on described die and punch (6) to be formed when matched moulds state by extruded for raw material for required form, during matched moulds, material returned support (15) is pressed down by past under the effect of extruding force, spring (16) is compressed simultaneously, after die sinking, material returned support (15) up moves and to be ejected by the product processed under the effect of spring (16) restoring force, thus complete product demoulding.Discharging device structure in hardware processing mold of the present invention, makes demoulding quick and convenient, and can not damage final products.
In addition, described die shoe (3) is fixedly installed support bar (17), described support bar (17) runs through lower bolster (3) and die block (7) successively and end, upper end exceeds die block (7), when punch (6) is depressed into extreme position, the upper surface of support bar (17) is connected with the lower surface of punch retainer (5), described support bar (17) plays again spacing effect, can prevent the multiple impacts of guide pillar up and down of rolling independent guide device (4) from causing wearing and tearing and causing the crushed position of punch, be used for ensureing the accuracy of extreme position, and then ensure that the precision of product.
In addition; lining (18) is arranged with outside described discharging device; described lining (18) is positioned between discharging device and die shoe (3); the hardness of described lining (18) is lower than material returned support (15) and die shoe (3); avoid material returned support (15) directly and die shoe (3) to mill, reduce and the wearing and tearing of material returned support (15) played a protective role.
The whole extrusion process of a kind of hardware diel of the present invention is simple, fast, its beneficial effect has: 1, reduce raw-material consumption; 2, effectively improve production efficiency; 3, the parts of higher dimensional precision and less surface roughness value can be obtained; 4, the cavity die structure of two-piece unit formula do not exist stress concentrate, die cracking phenomena has clear improvement.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
