Description
Technical field
It the utility model is related to auto parts machinery and prepare field, especially a kind of back axle spring panel seat shaving die.
Background technology
Rear axle housing assembly front end is to subtract assembly and transmission axis connection by main, and rear end is by latch plate seat assembly and automobile
Leaf spring or helical spring, are connected with vehicle frame.It directly affects ride comfort in bonding strength and running car, by property, reliability.Cause
The height of this spring panel seat both sides circular arc and the axiality of two circular arcs require higher, are required according to punching process character, in 90-degree bent
There is sufficiently long bending moment arm during angle, during to make bending, it is necessary to make bending height H>2t, and this spring panel seat middle circle arc is minimum
Bending height is much smaller than the minimum bend height required by sheet material, i.e., the sheet metal thickness less than 2 times (bends most short straight side length
For 9 ± 0.2mm, and workpiece thickness of slab is 6.0mm).If first to part deploy simultaneously blanking-punching, then directly bend, must
So it can cause straight flange is curved not come out, so that quality problems such as both sides crown height are unilateral, axiality is overproof.And press traditional work
Skill is to use:Blanking → blanking-punching → bending → plasma cut → and except cutting welding slag → shaping circular arc, set to reach product
Meter requires.Both sides circular arc is cut although with fine plasma cutting machine, but because fine plasma cuts machining accuracy
For ± 1.0mm, the uniformity of such workpiece is difficult to ensure that, both sides crown height and axiality are all difficult to reach requirement in addition, and
And high processing costs.Therefore, there is risk in the quality of product always.
Chinese patent notification number is that CN205853802U discloses a kind of automobile axle latch plate seat support attachment structure, it
Including rear axle housing body, latch plate seat support, latch plate seat support is welded on rear axle housing body, and leaf spring is arranged on spring
On panel seat support, two side height H1 on latch plate seat support with the welding of rear axle housing body are the half height of rear axle housing body one
More than the 1/2 of H2, in the case where ensureing matching requirements, latch plate seat support side width D is more than or equal to rear axle housing body one
Half height H2；Latch plate seat support upper thickness H3 is in 8 more than mm.There is presently no a set of cutting for back axle spring panel seat
Side mould, so by designing a kind of new shaving die and trimming technology, to ensure product quality uniformity, stability, just
Seem very necessary.
