Embodiment
The utility model is described further with specific embodiment below in conjunction with the accompanying drawings:
Aluminium sheet product trimming and piercing die lamps structure is the utility model is related to, including supports the lower mould 1 of aluminium sheet 3, match somebody with somebody with lower mould 1 The punching cutter block 2 of work is covered, lower mould edge mouth 1-1, the lower mould edge being arranged at below lower mould edge mouth 1-1 are respectively arranged with lower mould 1 Band 1-2, is punched the cutter block land 2-2 in cutter block 2 being respectively arranged with cutter block cutting edge 2-1, be arranged above cutter block cutting edge 2-1, under Blade clearance c is provided between mould edge mouth 1-1 and cutter block cutting edge 2-1, it is important to, described cutter block cutting edge 2-1 cross section is Circular arc, arc radius 0.3mm-0.5mm, arc radius is excessive, and cutter block cutting edge 2-1 can not cut off aluminium sheet 3, too small, be easy to Burr is produced, and arc radius is 0.3mm-0.5mm design, transition punching carries out micro- drawing to the aluminium sheet 3 at trimming and piercing die Stretch, easily be switched off aluminium sheet 3, and reduce frictions of the cutter block cutting edge 2-1 to aluminium sheet 3, reduce the generation of burr, described blade clearance C is 0.1t-0.12t, and wherein t represents the thickness of aluminium sheet, and blade clearance c meets the material capability of aluminium sheet 3, trimming and piercing die processing Aluminium sheet processing cross section quality is good afterwards, and impulse- free robustness produces, and blade clearance c reduces between lower mould 1 and punching cutter block 2, punching Friction between cutter block 2 and aluminium sheet 3, between waste material 4 and lower mould 1, both prevented burr from producing, product quality better, extended mould again Service life.
Preferably, described punching cutter block 2 is deburring cutter block, and the angle β between cutter block land 2-2 and vertical direction is 3 ° -5 °, described lower mould edge is 3 ° -5 ° with the angle α between 1-2 and vertical direction, the excessive cutter block cutting edge 2-1 of angle, lower mould Cutting edge 2-1 intensity differences, it is fragile, friction is also easy to produce between each part of angle too small, and be unfavorable for discharging waste material 4, this is designed into one Friction under step is reduced between mould 1 and punching cutter block 2, between punching cutter block 2 and aluminium sheet 3, between waste material 4 and lower mould 1, ensures mould Have intensity, effectively prevent burr from producing, discharge mould beneficial to waste material 4, while extend the mold use life-span.
Either, described punching cutter block 2 is punching cutter block, because punching cutter block 2 is universal smaller, to ensure to be punched cutter block 2 intensity, stability, cutter block land 2-2 are vertically set, and described lower mould edge is with the folder between 1-2 and vertical direction Angle α is 3 ° -5 °, the friction under further reducing between mould 1 and punching cutter block 2, between waste material 4 and lower mould 1, ensures that mould is strong Degree, land 2-2 effectively prevents burr from producing, while extends the mold use life-span.
Specific embodiment 1 as shown in figure 1, the trimming and piercing die lamps structure, including the lower mould 1 of support aluminium sheet 3, with lower mould 1 The punching cutter block 2 of auxiliary work, the thickness of aluminium sheet 3 is t, and lower mould 1 includes lower mould edge mouth 1-1, is arranged under lower mould edge mouth 1-1 The lower mould edge band 1-2 of side, punching cutter block 2 are specially deburring cutter block, including cutter block cutting edge 2-1, are arranged above cutter block cutting edge 2-1 Cutter block land 2-2, lower mould 1 is deburring punch-pin, and blade clearance c is provided between lower mould edge mouth 1-1 and cutter block cutting edge 2-1, punching Sanction gap c is 0.1t-0.12t, as the 2 of steelplate punching mould times, and cutter block cutting edge 2-1 is that cross section is circular arc, and circular arc is partly Footpath is 0.4mm, and the angle β between cutter block land 2-2 and vertical direction is 3 °, and lower mould edge is with the folder between 1-2 and vertical direction Angle α is 3 °, i.e., is changed to inclined edge band by perpendicular blade band.
During work, aluminium sheet 3 is placed on lower mould 1, and punching cutter block 2, holding pad are arranged on upper bolster, and upper bolster is to moving down Dynamic, holding pad touches material first, and holding pad compresses aluminium sheet 3 with lower mould 1, and upper bolster continues to move down, and the punching sword of cutter block 2 enters aluminium Plate 3, position to be punched is cut off.
Specific embodiment 2 is substantially the same manner as Example 1, and difference is to be punched the specially punching cutter block of cutter block 2, lower mould 1 is punching concave die, and cutter block land 2-2 is vertically set, and cutter block land 2-2 keeps perpendicular blade band, ensure that punching cutter block Strength and stability, prevent cutter block from damaging.
Technical scheme is inventor through the material for meeting aluminium sheet obtained by long-term experiment used by the utility model The punching scheme of energy, the cutter block cutting edge 2-1 shapes rounding that cutter block 2 will be just punched in the design phase is handled, and land is designed For inclined edge band, 10%-12% material thick clearance is realized by Computerized Numerical Control processing technology, it is final to ensure that pincers worker is debugged on pressing equipment Trimming-punching die suppresses qualified, carrot-free aluminium sheet product, high yield rate, reduces the rectification number of mould, avoids Aluminium sheet wastes, and ensure that mould strength, extends the mold use life-span, reduces production cost.
