The specific embodiment
As shown in Figure 1, the square inserted forging die of a kind of two-sided finish impression of the present invention comprises upper die and lower die, and the upper die and lower die structure is identical and be symmetrical structure, and described patrix comprises fixedly keyway 1, jaw 4, blocker 5, flash gutters 6 and finish impression 7.Fixedly keyway 1 is positioned at the upper end of patrix, be used for locating before and after the patrix, patrix left surface and right flank are provided with the location stationary plane, the location stationary plane is used for location and fixing about patrix, the location stationary plane comprises positioning reference plane 2 and constant inclined surface 3, positioning reference plane 2 and constant inclined surface 3 stretch out from die joint, positioning reference plane 2 and constant inclined surface 3 natural transition, the height of positioning reference plane 2 * length is 22mm * 380mm, the height of constant inclined surface 3 is 78mm, the oblique angle is 7 °, jaw 4 is positioned at the patrix upper surface, and connects with finish impression 7, and jaw 4 is for detection of the detection mouth of the liquid such as patrix impression cast paraffin, blocker 5 is positioned at die joint and near front end face, is used for blank base before finish-forging.Flash gutters 6 is used for holding the excess metal that finish impression 7 is extruded around finish impression 7 horizontal directions.
Described finish impression 7 is 2,2 finish impression 7 employings are dodged method and are arranged on the patrix, i.e. 2 finish impression 7 are reaching up and down left and right directions layout straggly, be that 2 vertical center lines of finish impression of patrix are not on same perpendicular, 1 finish impression 7 is positioned on the patrix upper surface, 1 finish impression is positioned on the patrix die joint, and 2 finish impression in the horizontal direction offset distance is 80mm, to guarantee not only compact conformation but also have enough wall thickness distance or working strength between the most two-sided finish impression of the same inserted forging die of easy inefficacy of stressed maximum.
Such as Fig. 1, Fig. 2 and shown in Figure 3, all take right positioner datum level 2 as design and positioning datum, the patrix length dimension relevant with this benchmark and counterdie length dimension have 85mm, 200mm and 250mm equidimension to the left and right directions of upper die and lower die.All take front end face as design and positioning datum, the length dimension relevant with this benchmark has 380mm to the fore-and-aft direction of upper die and lower die.Take right positioner datum level 2 and front end face as design and positioning datum can guarantee upper die and lower die about, about and fore-and-aft direction all have the identical benchmark of installing and using.Therefore, when installing and using, can guarantee patrix fixedly keyway 1 fixedly keyway, patrix right positioner datum level 2 can align, mate symmetrically or mutually use after installing and fixing with counterdie finish impression with counterdie finish-forging flash gutters, patrix finish impression 7 with counterdie blocker, patrix finish-forging flash gutters 6 with counterdie jaw, patrix blocker 5 with counterdie constant inclined surface, patrix jaw 4 with counterdie right positioner datum level, patrix constant inclined surface 3 fully mutually in the square die holder of inserting with counterdie.
The upper die and lower die of the square inserted forging die of two-sided finish impression of the present invention can Alternate, and namely patrix also can be used as counterdie and uses, and counterdie also can be used as patrix and uses.Patrix also can left rotation and right rotation 180 ° install and use, namely patrix can have 2 exchanges to install and use the position; Counterdie also can left rotation and right rotation 180 ° install and use, namely counterdie also can have 2 exchanges to install and use the position.Therefore, the upper die and lower die of square inserted forging die have respectively 4 different exchanges to install and use the position, and (the existing structure non-interchangeability only has respectively 1 to install and use the position to have absolute interchangeability.
A kind of square inserted forging die of two-sided finish impression, finish-forging flash gutters 6 is designed to symmetrical double-chamber type structure, be that the shape of flash gutters bridge section's die cavity of patrix and counterdie and flash gutters storehouse section die cavity and size are the up and down full symmetric structures take die joint as symmetrical centre, both can satisfy and hold the excess metal that flows into behind the die forging finish-forging in the flash gutters, be conducive to again manufacturing and the Alternate of inserted forging die.
A kind of square inserted forging die of two-sided finish impression, if the depth of die cavity of the upper die and lower die of same set of inserted forging die has notable difference, be that one of them impression of inserting is crossed dark and impression that another is inserted when more shallow, then can impression wherein is excessively dark, the low patrix (perhaps counterdie) of working strength is designed to traditional single face impression structure, and impression is more shallow, that working strength is higher counterdie (perhaps patrix) is two-sided finish impression structure.
A kind of square inserted forging die of two-sided finish impression, obviously different when the service life of the upper die and lower die of same set of inserted forging die, be that one of them is fragile and another is not when fragile, can be with wherein flimsy and non-damageable by the non-geometric ratio quantity configuration in 2: 1 or 3: 1 (existing same set of inserting up and down by geometric ratio quantity configuration in 1: 1 of inserting), with the unfavorable factor that effectively overcomes flimsy patrix (perhaps counterdie) corresponding non-damageable counterdie (perhaps patrix) is also scrapped in case scrap thereupon.
