Abstract
The utility model discloses a balance plate forging die resistance wall structure in middle of three jar bent axles includes multiaspect resistance wall for the middle balance plate die cavity of three jar bent axles is balance plate die cavities vertical and both ends and is on the forging die of horizontal. The middle balance plate die cavity of three jar bent axles be forging die that balance plate die cavities vertical and both ends are the horizontal include the mould and with last mould matched with lower mould, going up the mould and having offered the mould and become the die cavity, the lower mould corresponds to be gone up the mould and becomes the die cavity and offered lower mould one -tenth die cavity, the both sides that lower mould middle part qieyu lower mould becomes the die cavity are equipped with to the epirelief the resistance wall. The event, when forging, along with the blank is out of shape, the position of metal beginning intake resistance wall is because this is located the metal and is become the flow that has certain angle by the level flow to thickness also reduces, and metal flow horizontal direction resistance is showing to be increased. Consequently, the metal has increased the packing rate constantly to lower mould shaping chamber depths flow under the effect of forging and pressing power for the vertical balance plate of bent axle is filled fullly.
Description
Technical field

1, in the middle of bent axle, vertical balance plate cavity filling is not full;
2, the stock utilization of crankshaft forging is low, and forging economy is low.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, a kind of three cylinder crankshaft intermediate equilibria plate forging die resistance wall constructions are provided, its structure is simple, stable performance, add the ability hindering metal flow, metal constantly flows to die cavity depths under the effect of forging force, add filling rate, intermediate equilibria plate is filled full.
For achieving the above object, technical scheme provided by the utility model is:
A kind of three cylinder crankshaft intermediate equilibria plate forging die resistance wall constructions are vertical for the intermediate equilibria template chamber of three cylinder crankshafts and the balance plate die cavity at two ends is the forging die of horizontal, and this three cylinder crankshafts intermediate equilibria plate forging die resistance wall construction comprises multiaspect resistance wall.The intermediate equilibria template chamber of described three cylinder crankshafts is vertical and the forging die that the balance plate die cavity at two ends the is horizontal counterdie that comprises patrix and match with patrix, described patrix offers upper die forming chamber, the corresponding upper die forming chamber of described counterdie offers counterdie forming cavity, convexly in the both sides of counterdie forming cavity is provided with described resistance wall in the middle part of described counterdie.
Improve as one of the present utility model, described upper die forming chamber comprises multiple horizontal patrix balance plate die cavity being distributed in these two ends, upper die forming chamber, described horizontal patrix balance plate die cavity is interconnected, described counterdie forming cavity comprise multiple be distributed in these counterdie forming cavity two ends and with the horizontal counterdie balance plate die cavity of described horizontal patrix balance plate die cavity and multiple vertical balance plate die cavity be distributed in the middle part of this counterdie forming cavity, described horizontal counterdie balance plate die cavity and vertical balance plate die cavity are interconnected.
Improve as one of the present utility model, described three cylinder crankshaft intermediate equilibria plate forging die resistance wall constructions comprise two sides resistance wall, and it lays respectively at the lateral border of horizontal counterdie balance plate die cavity and vertical balance plate die cavity.
Improve as one of the present utility model, the outward-dipping certain angle of interior walls of described resistance wall.
The beneficial effects of the utility model are: the utility model three cylinder crankshaft intermediate equilibria plate forging die resistance wall construction due to described counterdie convexly in the both sides of counterdie forming cavity being provided with resistance wall, and described in lay respectively at the lateral border of horizontal counterdie balance plate die cavity and vertical balance plate die cavity.Therefore when forging, along with the continuation of blank deformation, metal starts the position of intake resistance wall, and because this place's metal becomes the flowing with certain angle from bottom horizontal flow sheet, and thickness also reduces, and metal flow horizontal direction resistance significantly increases.Therefore, the vertical balance plate die cavity depths flowing in metal continuous mold forming chamber downwards under the effect of forging force, adds filling rate, makes the vertical balance plate of middle bent axle fill full.

Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, the utility model three cylinder crankshaft intermediate equilibria plate forging die resistance wall construction, be vertical for the intermediate equilibria template chamber of three cylinder crankshafts and the balance plate die cavity at two ends is the forging die of horizontal, this three cylinder crankshafts intermediate equilibria plate forging die resistance wall construction comprises multiaspect resistance wall 3.The intermediate equilibria template chamber of described three cylinder crankshafts is vertical and the forging die that the balance plate die cavity at two ends the is horizontal counterdie 2 that comprises patrix 1 and match with patrix 1.Described patrix 1 offers upper die forming chamber 11, and the corresponding upper die forming chamber 11 of described counterdie 2 offers counterdie forming cavity 21, convexly in the both sides of counterdie forming cavity 11 is provided with described resistance wall 3 in the middle part of described counterdie 2.
Particularly, described upper die forming chamber 11 comprises multiple horizontal patrix balance plate die cavity 111 being distributed in these two ends, upper die forming chamber 11, described horizontal patrix balance plate die cavity 111 is interconnected, described counterdie forming cavity 21 comprise multiple be distributed in these counterdie forming cavity 21 two ends and with the horizontal counterdie balance plate die cavity 211 of described horizontal patrix balance plate die cavity 111 and multiple vertical balance plate die cavity 212 be distributed in the middle part of this counterdie forming cavity 21, described horizontal counterdie balance plate die cavity 211 and vertical balance plate die cavity 212 are interconnected.
In the present embodiment, described three cylinder crankshaft intermediate equilibria plate forging die resistance wall constructions comprise two sides resistance wall 3, it lays respectively at the lateral border of horizontal counterdie balance plate die cavity 211 and vertical balance plate die cavity 212, and then when forging, along with the continuation of blank deformation, metal starts the position of intake resistance wall, because this place's metal becomes the flowing with certain angle from bottom horizontal flow sheet, and thickness also reduces, metal flow horizontal direction resistance significantly increases.Therefore, metal is constantly depths, mold forming chamber 21 flowing downwards under the effect of forging force, adds filling rate, makes the vertical balance plate of middle bent axle fill full.
Refer to Fig. 3, in the present embodiment, the outward-dipping certain angle of interior walls of described resistance wall 3.
