The specific embodiment
As shown in Figures 1 to 7, the utility model provides a kind of lower inverted bell particular manufacturing craft, comprises punch 1, die 2 and blank holder 3, and 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, allow punch 1 be entrenched in inside, and portion moves within it simultaneously, and punch 1 is played to guide effect.
As shown in Figure 2 and Figure 3, the top of punch 1 has punch curved portions, and this punch curved portions comprises the large arc of punch portion 4 and is connected to the little arc of the punch portion 5 of the large arc of punch portion 4 both sides.The inside, one end of die 2 has die curved portions, and this die curved portions comprises the large arc of die portion 6 and is connected to the little arc of the die portion 7 of the large arc of die portion 6 both sides.The radius of the little arc of punch portion 7 is 50mm ~ 200mm, and when the radius of the little arc of punch portion 7 is 100mm ~ 150mm, the lower inverted bell result of use of making is better.Because steel have certain thickness, so the large 0mm ~ 10mm of radius of the little arc of the radius ratio punch portion 5 of the little arc of die portion 7, preferably 5mm.
In two outsides of die curved portions, be outer inclined-plane 8, outside both sides, between inclined-plane 8 and die curved portions, be provided with flange 10.It is identical with punch 1 profile that the inside of blank holder 3 has, the cavity 12 passing through for punch 1, and the port both sides of blank holder 3 are provided with interior inclined-plane 9, between interior inclined-plane 9 and cavity 12 ports, are provided with recessed edge 11.
When stamped lower inverted bell, first allow punch 1 enter in cavity 12, so the internal diameter of blank holder 3 internal cavities 12 need large 0mm ~ 5mm than the external diameter of punch 1, preferred 5mm.Steel are placed on blank holder 3, when punch 1 and die 2, under the effect at hydraulic press, push steel, make steel plate in the die curved portions moulding of die 2 inside, and the shape of moulding is determined by punch curved portions and the acting in conjunction of die curved portions.The arc of the little arc of the result of use of lower inverted bell and punch portion 5 and the little arc of die portion 7 has direct correlation.In punching course, the large arc of punch portion 4 is corresponding with the large arc of die portion 6, and the little arc of punch portion 5 is corresponding with the little arc of die 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 edges of blank holder 3 are 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 between flange 10 and recessed edge 11, forms a groove simultaneously.After steel plate punched moulding, by this groove, can realize cutting, obtain finished product lower inverted bell.
Outer inclined-plane 8 on die 2, refers to that the height of this inclined-plane in die 2 inner sides is greater than outside, the interior inclined-plane 9 of blank holder 3 refer to this inclined-plane at the height of blank holder 3 inner sides lower than outside.In implementation process, the inclination angle that outer inclined-plane 8 is set is 6 ~ 15 °, and the inclination angle on interior inclined-plane 9 is 6 ~ 15 °.
When implementing the utility model, 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 punching press, at steel plate, enters behind its inside, need to be by Bas Discharged, otherwise will increase stamping press, and therefore at the middle part of die curved portions, be provided with air-vent 15, discharge the air of die curved portions.
The radius of the large arc of punch portion 4 is 2800mm ~ 3200mm, the large 0mm ~ 10mm of radius of the large arc of the radius ratio punch portion 4 of the large arc of die portion 6.The change in radius of the large arc of punch portion 4 and the large arc of die portion 6 can regulate the overall dimensions of lower inverted bell, when lower inverted bell overall dimensions changes, and the size generation respective change of the corresponding large arc of punch portion 4, the little arc of punch portion 5, the large arc of die portion 6 and the little arc of die portion 7.In the utility model, the large arc of punch portion 4, the little arc of punch portion 5, the large arc of die portion 6 and the little arc of die portion 7 are the minor arc on respective radius circle, major arc if, can not produce lower inverted bell, through calculating, the central angle of the large arc of punch portion 4 and the little arc of punch portion 5 is not more than 90 degree, and place arc is not more than 1/4th circular arc, corresponding, the central angle of the large arc of die portion 6 and the little arc of die portion 7 is also not more than 90 degree.Preferably, the central angle of the little arc of punch portion 5 and the little arc of die portion 7 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 the large arc of punch portion 4 and the large arc of die portion 6, and the edge of lower inverted bell has a larger radian, and this radian is by the little arc of punch portion 5 and the little arc of die portion 7 co-controllings.The pouring glaze effect of lower inverted bell is mainly subject to the impact of the little arc of punch portion 5 and the little arc of die portion 7, on its top cover less radian be mainly used in being convenient to paint can be along under lower inverted bell outer wall dispersion train.For determining of arc, major parameter has radius, chord length, arc length and central angle etc.One end of the little arc of punch portion 5 is connected with flange 10, the other end is connected with the large arc of punch portion 4, the position being wherein connected with flange 10, the tangent line of its camber line is vertical with horizontal line, and the tangent line of the other end and the large arc of this place's punch portion 4 are identical or make the large arc of punch portion 4 smooth smooth and easy with being connected of the little arc of punch portion 5 at the tangent line with its tie point.
According to the lower inverted bell size that will make, the total chord length A that controls the large arc of punch portion 4 is 300mm ~ 1800mm, is highly H100mm ~ 250mm.The large arc of die portion 6 is than the long 0 ~ 10mm of total chord length of the large arc of punch portion 4, highly high 0 ~ 5mm.When total chord length A of the large arc of punch 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, can suitably adjust the parameter of height.The size of die 2 is large compared with punch 1, is because steel have certain thickness, so its chord length and highly slightly large compared with punch 1.
Punch 1 and die 2 have a base, and base is cylindrical, and base can, for solid, be used steel manufacture.But solid mould has larger weight, the material of use is also more, due to what work on punch 1 and die 2, is mainly arch section, therefore in the inside of punch 1 and die 2, is provided with hollow-out parts 16, is provided with reinforcement 17 in hollow-out parts 16.Hollow-out parts 16 is for reducing material, weight reduction.After inner hollow out, its intensity will be affected, and therefore add reinforcement 17 and guarantee stressed strength and stiffness.
