Description
Technical field
The utility model relates to a kind of extrusion molding dies, specifically refers to a kind of Combined oxygen gun jet top trunnion one extrusion molding dies.
Background technology
Oxygen rifle is one of major process unit in oxygen converter steelmaking, and its performance characteristic directly has influence on metallurgical effect and duration of blast, thus has influence on the Quality and yield of steel; Wherein, the various process parameters of oxygen gun sprayer and Optimal Structure Designing particularly important.At present, the upper parts of Combined oxygen gun jet oxygen gun sprayer in the manufacturing and oxygen spraying hole trunnion be respectively shaping after Combination Welding structure, this split welding procedure is mainly artificial gas brazing, easy generation solder joint defect, qualification rate is only about 80%, repair rate is higher, not only increases the manufacturing cost of Combined oxygen gun jet, and in production and application, there is certain potential safety hazard.Therefore, manufacture integrated combined type oxygen gun sprayer and will there is larger market efficiency and economic benefit.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of Combined oxygen gun jet top trunnion one extrusion molding dies, effectively reduces processing cost, improves the safe application performance of product, and rational in infrastructure, is easy to the demoulding.
The utility model takes following technical scheme:
A kind of Combined oxygen gun jet top trunnion one extrusion molding dies, described mould comprises die combination and lower die combination, described upper die combination is made up of upper bolster, punch, punch trim ring, punch trim ring is fixed on upper bolster, punch one end is installed in punch trim ring, the punch other end extends in lower die combination, and described lower die combination comprises die shoe, cranse and several die, and forms mold cavity by each die; Described cranse upper end is fixed by pressing plate, and cranse bottom and die shoe are fixed, and the centre position of described die shoe is provided with a jacking block; Described each die is arranged on by the cavity in die shoe, jacking block and cranse besieged city.
Described die is made up of die I, die II and die III, and described die I is arranged at die II upper end, and die I is sleeved on described punch, and die III is installed in die II, and described jacking block contacts with die II die III.
Described cranse comprises cranse I and cranse II, and cranse I is sleeved on die I, and cranse II is sleeved on die II; Cranse I upper end and pressing plate affixed, cranse II bottom and die shoe affixed, fixed by securing member between cranse.
Described die I is 4-6 the bulk-breaking such as grade circumferentially arranged.
Described die III is 3 bulk-breakings such as grade circumferentially arranged.
The beneficial effects of the utility model: Combined oxygen gun jet upper parts adopts one extrusion molding dies with spray oxygen trunnion, extrude blank and decrease one solder joint structure in the mill, effectively simplify process flow, reduce processing cost, improve the safe application performance of product; The Optimal Structure Designing of lower die combination, is suitable for the class of falling withdrawing pattern part, can be conveniently stripped, can ensure again the specification requirement of extrusion blank part, improve workpiece accuracy, rational in infrastructure, simple to operate, is suitable for extensive use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of oxygen gun sprayer blank in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model and effect thereof are described further.
As shown in Figure 1, a kind of Combined oxygen gun jet top trunnion one extrusion molding dies, described mould comprises die combination and lower die combination, described upper die combination is made up of upper bolster 1, punch 2, punch trim ring 3, punch trim ring 3 is bolted on upper bolster 1, and described punch 2 one end is installed in punch trim ring 3, and punch 2 other end extends in lower die combination, its termination is cambered surface, is formed the profile of oxygen spraying hole trunnion by punch 2; Described lower die combination comprises die shoe 7, cranse and several die, and forms mold cavity 9 by each die; Cranse upper end is fixed by pressing plate 4, and cranse bottom is bolted on die shoe 7, and the centre position of described die shoe 7 is provided with a jacking block 10; Described each die is arranged on by the cavity in die shoe 7, jacking block 10 and cranse besieged city.
Described die is made up of die I 12, die II 8 and die III 11, and described die I 12 is arranged at the upper end of die II 8, and die I 12 is sleeved on described punch 2, and die III 11 is installed in die II 8, and described jacking block 10 contacts with die II 8, die III 11.Described cranse comprises cranse I 5 and cranse II 6, and cranse I 5 is sleeved on die I 12, and cranse II 6 is sleeved on die II 8, and cranse I 5 upper end is fixed by pressing plate 4, and cranse II 6 bottom is bolted on die shoe 7, affixed by bolt between cranse.
In production operation, be first fixed on hydraulic press upper table by upper bolster 1, die shoe 7 is fixed on hydraulic press lower table.Then the oxygen-free copper copper material that size is applicable to being heated to uniform temperature at heating furnace is placed in mold cavity 9, after primer fluid press, be expressed to certain position downwards by punch 2, oxygen-free copper copper material is shaping in the die cavity formed by each die in lower die combination, becomes oxygen gun sprayer, when the demoulding, because oxygen gun sprayer molded blank part is dish type class part, the n-φ d that shower nozzle protrudes as shown in Figure 2 is cylinder, generally be uniformly distributed along the circumference 4 ~ 6, and hold α angle with central axis, it is easily caused to be out of shape according to normal stripping means, the specification requirement of extrusion blank part cannot be ensured, therefore in design, the die I 12 of annular is set to circumferentially 4-6 bulk-breaking such as grade according to extrusion blank shape, 3 that are set to by die III 11 be uniformly distributed along the circumference are waited bulk-breaking, after blank is extruded, clamping cap 4 is dismantled, taken blame for others after extrusion blank part and each die entirety are ejected disengaging by jacking jacking block 10 by hydraulic press and again the die of Split type structure is removed, take out extrusion blank part complete operation.
