Abstract
The utility model relates to an integrative mould is forged in shaping of scraper blade machine dumbbell round pin, including last mould and lower mould, upward all be provided with the finish forging die cavity on mould and the lower mould, upward the shape of finish forging die cavity is the same with dumbbell round pin shape behind mould and the lower mould compound die, all still be equipped with the base die cavity on going up mould and lower mould, upward the shape of base die cavity is the same with the shape of dumbbell round pin base behind mould and the lower mould compound die, base die cavity and finish forging die cavity adjacent arrangement. Adopt the utility model discloses the very big reduction of structure the base cost, when shortening the worker, convenient operation has improved base precision and product production efficiency.
Description
Technical field
The utility model belongs to foundry goods technical field of forging, is specifically related to the shaping forging integration mold of a kind of scrapper conveyor dumbbell pin.
Background technology
Dumbbell pin is as the connecting elements between the adjacent two joint chutes of scrapper conveyor conveyer, and the normal operation for guarantee drag conveyor plays an important role.Dumbbell pin is once fracture can cause intermediate channel connecting staggered or disengagement, and then chain jamming is even deviate from from chain road to cause scraper chain and scraper plate to occur, affects the normal work of whole working face.In native land, dumbbell pin is Integral die-forged part substantially, and one forging, both ensure that metallic fiber streamline, and turn improved product strength and toughness.
But due to the shape particularity of dumbbell pin forging, the minimum and maximum area of section of forging differs ten times more than, belong to different in nature complex die forging, therefore before mould finish forging, in order to improve die life, ensure enough mold-filling capacity, needed blank base, stock volume is redistributed along axis.Domestic dumbbell pin Ge great manufacturing firm substantially all adopts open die forging base, and then die forging type hammer out, there is following problem like this: 1, base needs an independent operation 2, activity time longer, and cutting stock weight additionally increases.
Utility model content
There is provided a kind of scrapper conveyor dumbbell pin shaping forging integration mold to solve prior art problem, this structure greatly reduces base cost, shorten manufacturing man-hours, handled easily, improve base precision and production efficiency, both reduce the cost of dumbbell pin forging, in turn ensure that product quality.
For achieving the above object, the utility model adopts following technical scheme:
The shaping forging integration mold of a kind of scrapper conveyor dumbbell pin, comprise upper die and lower die, upper die and lower die are provided with finish-forging die cavity, after upper die and lower die matched moulds, the shape of finish-forging die cavity is identical with dumbbell pin shape, described upper die and lower die are all also provided with base die cavity, after upper die and lower die matched moulds, the shape of base die cavity is identical with the shape of dumbbell pin base, base die cavity layout adjacent with finish-forging die cavity.
Described base die cavity communicates with finish-forging die cavity.
The difference of the size of the thin neck of size and centre of the thick neck in end of described dumbbell pin base is 6 ~ 12mm.
Described patrix is die, and counterdie is punch.
compared with prior art, the beneficial effects of the utility model:
1. adopt the utility model structure, reduce by a fire preparing base fire, reduction cutting stock weight about 5%.
2, mold cavity is compact, under ensureing the prerequisite in service life, decreases die manufacturing cost.
3, the control of base die cavity critical size, ensure that base efficiency, avoids the generation of forging defects such as folding simultaneously, ensure that the dimensional accuracy of precut blanks.
4, base and finish-forging are shaped, and a fire is secondary to be completed, and operation is continuous, improves production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model upper die structure schematic diagram;
Fig. 2 is the utility model lower die structure schematic diagram;
Fig. 3 is A-A partial schematic sectional view in Fig. 2;
Fig. 4 is B-B partial schematic sectional view in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Shown in composition graphs 1 ~ 4, the shaping forging integration mold of a kind of scrapper conveyor dumbbell pin, comprise patrix 1 and counterdie 2, patrix 1 is die, and counterdie 2 is punch; Patrix 1 and counterdie 2 are provided with finish-forging die cavity 3, after upper die and lower die matched moulds, the shape of finish-forging die cavity is identical with dumbbell pin shape, described upper die and lower die are all also provided with base die cavity 4, after upper die and lower die matched moulds, the shape of base die cavity is identical with the shape of dumbbell pin base, base die cavity layout adjacent with finish-forging die cavity, base die cavity communicates with finish-forging die cavity; Wherein, the difference of the size of the thin neck of size and centre of the thick neck in the end of dumbbell pin base is 6 ~ 12mm.
Claims (4)
1. the shaping forging integration mold of scrapper conveyor dumbbell pin, comprise upper die and lower die, upper die and lower die are provided with finish-forging die cavity, after upper die and lower die matched moulds, the shape of finish-forging die cavity is identical with dumbbell pin shape, it is characterized in that: described upper die and lower die are all also provided with base die cavity, after upper die and lower die matched moulds, the shape of base die cavity is identical with the shape of dumbbell pin base, base die cavity layout adjacent with finish-forging die cavity.
