Channel bend pressing mold.
In order to solve the above technical problems, the utility model is realized using following technical scheme:
A kind of high-pressure exhaust pipe road elbow pressing die, which is characterized in that including
The lower die of one installation on the lower die seat, it is semicircular cavity plate, the cavity plate that cross section is equipped in the lower die
Top edge and lower die between using arc transition connect, the two sides of the lower die bottom be respectively equipped with facilitate lifted to
The lower die lifting lug sling on lower die holder or from lower die holder；
One is mounted on upper die holder and upper mold corresponding with lower die, is equipped in the upper mold corresponding and horizontal with cavity plate
Section is semicircular punch-pin, and the two sides at the top of the upper mold are respectively equipped with to facilitate and be lifted to upper die holder or from upper die holder
On the upper mold lifting lug sling.
In a preferred embodiment of the utility model, limit is respectively equipped in the upper mold and positioned at the two sides of punch-pin
Position item, the positive stop strip extend along the top edge of punch-pin.
In a preferred embodiment of the utility model, in the lower die and it is located on the side of cavity plate equipped with positioning
Item, the positioning strip extend along the top edge of cavity plate.
Compared with prior art, the utility model is equipped with lower die and upper mold, be equipped in lower die cross section be it is semicircle and
Whole cavity plate identical with the half structure of elbow that will be welded, is equipped with punch-pin corresponding with cavity plate in upper mold, uses
Two and half elbow structures being pressed into can be welded into the elbow of an entirety by such structure, have the elbow being welded
The advantages of tube wall is smooth, resistance is small, not easy to wear and long service life.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to shown in Fig. 2-Fig. 6, a kind of high-pressure exhaust pipe road elbow pressing die provided in figure, including lower die 100 and upper mold
200。
Lower die 100 is installed on the lower die seat, and it is semicircular cavity plate 110, cavity plate 110 that cross section is equipped in lower die 100
Top edge and lower die between connected using arc transition 140, adopt the structure convenient for by half elbow 300 after compression moulding
Structure is taken out from cavity plate 110, operates convenient for operator.
It is respectively equipped with to facilitate in the two sides of 100 bottom of lower die and be lifted under being sling on lower die holder or from lower die holder
Mould lifting lug 120, when lifting lower die, it is only necessary to which the suspension hook of hanging apparatus is hung on lower die lifting lug 120 can be more convenient
Lower die is lifted on lower die holder or from lower die holder and slings, lifting work is carried out to lower die 100 convenient for operator.
Upper mold 200 is mounted on upper die holder and corresponding with lower die, be equipped in upper mold 200 it is corresponding with cavity plate 110 and
