The specific embodiment
The structure that Figure of description illustrates, ratio, size etc., equal contents in order to cooperate specification to disclose only, understand and reading for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
Shown in Figure 5 is the schematic diagram of thin web plate fork-shaped Shell Forging Parts.Thin web plate fork-shaped Shell Forging Parts comprises body 5, left fork pawl 51 and right fork pawl 52, and convex tendon and groove.
According to Fig. 1-Fig. 4, a kind of mould structure of thin web plate fork-shaped Shell Forging Parts, comprise patrix 1 and counterdie 2, the bottom of described counterdie 2 is installed on the base plate 3, slideway 4 is arranged on the base plate 3, and counterdie 2 can switch between a blocking position 25 and a finish-forging position 26 by sliding at slideway 4, and described patrix 1 is provided with patrix finishing cavity 12, described counterdie 2 is provided with blocking type groove 21 and finishing cavity 22, and blocking type groove 21 and finishing cavity 22 are arranged along the glide direction of counterdie 2.
This mould structure is installed on same the forging equipment, and the patrix 1 of described mould structure is fixedly mounted on the upper installation table top of forging equipment, and the counterdie 2 of described mould structure is installed on the lower installation table top by base plate 3.Preferably, described slideway 4 is the dovetail grooves 31 that are opened on the base plate 3, and counterdie 2 bottom surfaces are provided with dovetail guide 24, and dovetail groove 31 and dovetail guide 24 are slidingly matched.
Preferably, described patrix 1 is provided with a plurality of detents 11, and counterdie 2 is provided with the positioning convex column 23 of a plurality of and described detent 11 couplings.Further, four jiaos of described patrix 1 are provided with four detents 11, described counterdie 2 is provided with six positioning convex column 23, when counterdie 2 is in blocking position 25 and finish-forging position 26, plays the effect of guide-localization thereby all have four positioning convex column 23 and described four detents 11 to align.
In the time of work, first with blocking type groove 21 consistencies from top to bottom of patrix finishing cavity 12 with counterdie 2, can position and lead by four detents 11 on the patrix 1 and four positioning convex column 23 around the blocking type groove on the counterdie 2 21, at this moment, form the blocking die cavity by the blocking type groove 21 on patrix finishing cavity 12 and the counterdie 2, the blank that heats is placed on the blocking type groove 21 carries out blocking.Behind the blocking, because the fillet size of the blocking type groove 21 on the counterdie 2 is larger, forges good blank and be bonded on the patrix 1.Then, again counterdie 2 is spurred forward along slideway 4, make finishing cavity 22 consistencies from top to bottom on patrix finishing cavity 12 and the counterdie 2, form the finish-forging die cavity by the finishing cavity 22 on patrix finishing cavity 12 and the counterdie 2, and by four detents 11 on the patrix 1 and four positioning convex column 23 correctings alignment around the counterdie finishing cavity 22, carry out finish-forging.Because the fillet of the finishing cavity 22 on the counterdie 2 is smaller, the forging behind the finish-forging rests on the counterdie, carries out next step operation thereby make things convenient for the workman will forge good workpiece taking-up.
After finish-forging finishes, counterdie 2 is promoted backward again, patrix finishing cavity 12 is alignd with blocking type groove 21 on the counterdie 2, carry out the forging of next forging.
In sum, the mould structure of this thin web plate fork-shaped Shell Forging Parts, can carry out the processing of blocking and finish-forging at same equipment, the complicated heavy forging of realization is produced at a large equipment, take full advantage of existence conditions, effectively save cost, and can not cause damage to equipment and mold because off-centre is hit.Therefore the utility model has very high popularizing value aspect forging.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.The utility model also many aspects can also improve such as the locate mode of upper die and lower die, the structure of slideway etc. under the prerequisite of overall thought.Therefore, all can be under spirit of the present utility model and category for person skilled in the art scholar, can modify or change above-described embodiment.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that the utility model discloses and the technological thought, must be contained by claim of the present utility model.
