Abstract
The utility model discloses an upright eight-petal bulging die, which comprises an upper die plate and a lower die plate. A fixed plate is fixedly mounted on the lower surface of the upper die plate, a pressing plate is connected to the lower side of the fixed plate by a spring, a cone is further fixedly connected to the lower side of the pressing plate, a flange is fixedly mounted on the upper surface of the lower die plate, an eight-petal bulging mandrel is disposed in the flange, the cone is inserted into the eight-petal bulging mandrel, a bulging workpiece is further sleeved on the outside of the eight-petal bulging mandrel, and columns with the same heights are further fixedly mounted between the upper die plate and the lower die plate. The upright eight-petal bulging die is simple in structure, easy in manufacture and convenient in operation, a bulging core die is an eight-petal type split structure, wire drawing of products and abrasion of the die can be effectively eliminated, and the dimensional stability of the products is guaranteed.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of vertical type eight lobe bulging dies.
Background technology
Bulging die is in the internal shape cavity of pipe fitting, enlarges through the size of bulging core with workpiece, is prone to die wear and product inner surface in the bulging process and produces the wire drawing phenomenon.Need the bulging core be adopted for this reason and divide body structure, cut tapering (the shape chamber of a cone is cut in the centre), again core is divided into eight equal parts in the middle of the core.Need the workpiece of bulging to insert in the eight lobe bulging dies after cutting apart, utilize a cone plug that eight lobe bulging dies are swollen, thereby reach the purpose that product swells, thereby can guarantee that like this wire drawing, and the phenomenon of die wear appear in product in the bulging process.
The utility model content
The used solution of the utility model technical problem provide a kind of vertical type eight lobe bulging dies; The utility model is simple in structure, making is easy, easy to operate, bulging core adopts eight lobes to divide body structure; Can effectively solve the generation of product wire drawing, die wear phenomenon, product size is stable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Vertical type eight lobe bulging dies include cope match-plate pattern and lower bolster, it is characterized in that: be installed with fixed head on the lower surface of said cope match-plate pattern; Described fixed head below is connected with holding pad through spring; Described holding pad below also is fixedly connected with cone, is installed with flange on the upper surface of said lower bolster, is provided with eight lobe bulging cores in the described flange; Described cone is inserted in the eight lobe bulging cores, and described eight lobe bulging cores also are with bulging operation part outward.
Described vertical type eight lobe bulging dies is characterized in that: Gao Zhu such as also be installed with between described cope match-plate pattern and the lower bolster.
The advantage of the utility model:
The utility model is simple in structure, making is easy, easy to operate, bulging zinc mould adopts eight lobe formulas to divide body structure, can effectively remove the generation of product wire drawing, die wear phenomenon, and product size is stable.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
Embodiment: referring to Fig. 1, vertical type eight lobe bulging dies include cope match-plate pattern 9 and lower bolster 1; Be installed with fixed head 8 on the lower surface of cope match-plate pattern 9; Fixed head 8 belows are connected with holding pad 7 through spring 10, and holding pad 7 belows also are fixedly connected with cone 6, are installed with flange 3 on the upper surface 2 of lower bolster 1; Be provided with eight lobe bulging cores 4 in the flange 3; Cone 6 is inserted in the eight lobe bulging cores 4, also is with bulging operation part 11 outside the eight lobe bulging cores 4, also is installed with post such as height such as grade 5 between cope match-plate pattern 9 and the lower bolster 1.
