Detailed description of the invention
As shown in Figures 1 to 7, the invention provides a kind of lower inverted bell particular manufacturing craft, comprise punch 1, die 2 and blank holder 3, the profile of punch 1, die 2 and blank holder 3 is cylinder.Punch 1 and die 2 are for by steel punch forming, and blank holder 3, for placing steel, allows punch 1 be entrenched in inside simultaneously, and moves therein, play guide effect to punch 1.
As shown in Figure 2 and Figure 3, the top of punch 1 has punch curved portions, and this punch curved portions comprises punch large arc portion 4 and is connected to the little arc portion 5 of punch of both sides, punch large arc portion 4.The inside, one end of die 2 has die curved portions, and this die curved portions comprises die large arc portion 6 and is connected to the little arc portion 7 of die of both sides, die large arc portion 6.The radius in the little arc portion 7 of punch is 50mm ~ 200mm, and when the radius in the little arc portion 7 of punch is 100mm ~ 150mm, the lower inverted bell result of use of making is better.Because steel have certain thickness, the therefore large 0mm ~ 10mm of radius in the radius ratio punch little arc portion 5 in die little arc portion 7, preferred 5mm.
Be outer inclined-plane 8 outside two of die curved portions, outside both sides, between inclined-plane 8 and die curved portions, be provided with flange 10.The inside of blank holder 3 has identical with punch 1 profile, and for the cavity 12 that punch 1 passes through, the port both sides of blank holder 3 are provided with interior inclined-plane 9, are provided with recessed edge 11 between interior inclined-plane 9 and cavity 12 port.
When stamped lower inverted bell, first allow punch 1 enter in cavity 12, therefore the internal diameter of blank holder 3 internal cavity 12 needs large 0mm ~ 5mm than the external diameter of punch 1, preferred 5mm.Steel are placed on blank holder 3, extrude steel when punch 1 and die 2 under the effect at hydraulic press, make steel plate shaping in the die curved portions of die 2 inside, and shaping shape is determined by punch curved portions and the acting in conjunction of die curved portions.The arc in the result of use of lower inverted bell and punch little arc portion 5 and the little arc portion 7 of die has direct correlation.In punching course, punch large arc portion 4 is corresponding with die large arc portion 6, and punch little arc portion 5 is corresponding with die little arc portion 7.The shape of die curved portions forms the shape of lower inverted bell outer surface, and the shape of punch curved portions forms the shape of lower inverted bell inner surface.
The edge of die curved portions is provided with flange 10, and cavity 12 edge of blank holder 3 is provided with recessed edge 11, and flange 10 is the circular arc of radius 3mm ~ 15mm; Recessed edge 11 is the circular arc of radius 3mm ~ 15mm.When punching press, flange 10 enters recessed edge 11 inside, and the steel generation deformation simultaneously between flange 10 and recessed edge 11, forms a groove.After steel plate punched is shaping, can cutting be realized by this groove, obtain finished product lower inverted bell.
Outer inclined-plane 8 on die 2, refer to that the height of this inclined-plane inside die 2 is greater than outside, the interior inclined-plane 9 of blank holder 3 refers to that the height of this inclined-plane inside blank holder 3 is lower than outside.In implementation process, the inclination angle arranging outer inclined-plane 8 is 6 ~ 15 °, and the inclination angle on interior inclined-plane 9 is 6 ~ 15 °.
When implementing of the present invention, because the power of punching press is very large, need to position punch 1, die 2 and blank holder 3.The sidewall of punch 1, die 2 and blank holder 3 is provided with hole for hoist 13, and punch 1 and blank holder 3 are provided with locating hole 14, and hole for hoist 13 and locating hole 14 are all for being fixed on lathe by three.
Die curved portions is inner gassy before stamping, after steel plate enters its inside, needs air to discharge, otherwise will increase stamping press, be therefore provided with air-vent 15 at the middle part of die curved portions, discharge the air of die curved portions.
The radius in the large arc portion 4 of punch is 2800mm ~ 3200mm, the large 0mm ~ 10mm of radius in the radius ratio punch large arc portion 4 in die large arc portion 6.The radius change in punch large arc portion 4 and the large arc portion 6 of die can regulate the overall dimensions of lower inverted bell, when lower inverted bell overall dimensions changes, and the size generation respective change in corresponding punch large arc portion 4, punch little arc portion 5, die large arc portion 6 and the little arc portion 7 of die.In the present invention, punch large arc portion 4, punch little arc portion 5, die large arc portion 6 and the little arc portion 7 of die are the minor arc on respective radius circle, if be major arc, lower inverted bell can not be produced, through calculating, the central angle in punch large arc portion 4 and the little arc portion 5 of punch is not more than 90 degree, and namely place arc is not more than the circular arc of 1/4th, corresponding, the central angle in die large arc portion 6 and the little arc portion 7 of die is also not more than 90 degree.Preferably, the central angle in punch little arc portion 5 and the little arc portion 7 of die is between 45 degree ~ 90 degree.
The profile of lower inverted bell is as top cover, and upper end has a less radian, and this radian is controlled by punch large arc portion 4 and the large arc portion 6 of die, and the edge of lower inverted bell has a larger radian, and this radian is by punch little arc portion 5 and die little arc portion 7 co-controlling.The pouring glaze effect of lower inverted bell is mainly subject to the impact in punch little arc portion 5 and the little arc portion 7 of die, and radian less on its top cover is mainly used in being convenient to paint can along under lower inverted bell outer wall dispersion train.For the determination of arc, major parameter has radius, chord length, arc length and central angle etc.The one end in the little arc portion 5 of punch is connected with flange 10, the other end is connected with the large arc portion 4 of punch, the position be wherein connected with flange 10, the tangent line of its camber line and horizontal line, the tangent line of the other end and this place's punch large arc portion 4 are identical with the tangent line of its tie point or make the connection in punch large arc portion 4 and punch little arc portion 5 smooth smooth and easy.
According to the lower inverted bell size that will make, the total chord length A controlling punch large arc portion 4 is 300mm ~ 1800mm, is highly H100mm ~ 250mm.Die large arc portion 60 ~ 10mm, highly high 0 ~ 5mm longer than total chord length in punch large arc portion 4.When total chord length A in punch large arc portion 4 is 300mm, for the manufacture of undersized lower inverted bell, now height H is 100mm, when total chord length is 1800mm, is highly arranged to 250mm.Therefore, when total chord change, the parameter of height suitably can be adjusted.The size of die 2 comparatively punch 1 is large, is because steel have certain thickness, therefore its chord length and highly comparatively punch 1 is slightly large.
Punch 1 and die 2 have a base, and base is cylindrical, and base can be solid, use steel manufacture.But solid mould has larger weight, the material of use is also more, is mainly arch section, is therefore provided with hollow-out parts 16 in the inside of punch 1 and die 2, is provided with reinforcement 17 in hollow-out parts 16 due to what punch 1 and die 2 worked.Hollow-out parts 16 for reducing material, weight reduction.When after inner hollow out, its intensity will be affected, and therefore add reinforcement 17 and ensure stressed strength and stiffness.
