The tuyere cap mould is structurally characterized in that: the primary extrusion convex die comprises a first base, the first base is provided with a ring bulge, and the inner and outer sides of the ring bulge are respectively provided with a dip angle; and the secondary extrusion convex die is composed of a second base and a conical bulge on the second base.
Description
Technical field
The utility model belongs to field of machining, and in particular, the utility model relates to the mould of a kind of air port cap.
Background technology
The blast-furnace tuyere cap generally is formed by connecting two different Taper Pipes of diameter, and prior manufacturing method has two kinds: the one, and casting; The 2nd, welding fabrication.
The defective of casting has: 1, the separate room feeds intake weight up to 150% of finished weight, strengthens the occupation of capital and follow-up machining amount.
2, casting mold cavity complicated, can not reuse, be unfavorable for metal flow, lumber recovery is low.
3, the environment that solidifies of metallic crystal is different, and interior tissue and mechanical strength are inhomogeneous.
4, metal only depends on gravity flow, solidifies, and density is little, intensity is low, and service life is short.
The defective of welding fabrication has: 1, two Taper Pipes are obtained by different process, and interior tissue and overall mechanical strength are inconsistent.
When 2, welding, two parts that interior tissue is different link together, and cause local internal stress excessive, reduce service life.
3, the front end of weld seam cap in the air port is in material and the abominable working environment that slag impacts, and reduces service life once more.
4, the welding fabrication operation is many, and the process-cycle is long, not only loses time but also be difficult to guarantee product quality.
Summary of the invention
The utility model is exactly to the problems referred to above, provides that a kind of air port cap of producing is with low cost, long service life, processing technology one double taper pipe extruding air port hat cone tool simply in the same way.
For realizing the above-mentioned purpose of the utility model, the utility model adopts following technical scheme, and the utility model comprises with the corresponding die of air port cap outer shape, once pushes punch and secondary extrusion punch; The die bottom is provided with push rod, and the described punch that once pushes of its structural feature comprises first pedestal, and first pedestal is provided with annular protrusion, and the side, inside and outside both sides of said annular protrusion all is provided with the inclination angle; Described secondary extrusion punch is made up of the truncated cone-shaped convexity on second pedestal and second pedestal.
A kind of preferred version as the utility model: the utility model also comprises secondary extrusion protection mould, and described secondary extrusion protection mould comprises conical tube, and the gradient of conical tube lateral surface is identical with the lateral surface gradient of once pushing the punch annular protrusion; The gradient of conical tube medial surface is identical with the protruding lateral surface gradient of secondary extrusion punch truncated cone-shaped; The end that the conical tube diameter is bigger is outside equipped with spacing platform, is provided with groove corresponding to spacing platform on the die; The die top is provided with the fixed head of secondary extrusion protection mould corresponding to spacing platform.
Further, said secondary extrusion protection mould is combined by at least three mold monomers.
The beneficial effect of the utility model: 1, product quality is high: for casting technique, use the utility model production air port cap, during extruding, three of material internals are stressed, and dense structure is continuous, and intensity is high; Welding procedure has reduced welding sequence one relatively, improves the mechanical strength and the service life of air port cap.
2, production efficiency is high: adopt the utility model production air port cap, and precision size in the time of can making the air port cap forming, blank reservation amount seldom significantly reduces processing capacity; And do not have welding sequence, reduce whole process time.
3, economical with materials: use the utility model production air port cap, the weight few 40% that feeds intake of the weight ratio casting technique production air port cap that feeds intake of single workpiece; Therefore, significantly reduced the input of required fuel, electric power, manual work and equipment of Metal Melting; Can also reduce emission amount of carbon dioxide, meet the requirement of low-carbon economy development key element.

The specific embodiment
The utility model comprises with the corresponding die 1 of air port cap outer shape, once pushes punch 5 and secondary extrusion punch 10; Die 1 bottom is provided with push rod 6, and the described punch 5 that once pushes comprises that first pedestal, 3, the first pedestals 3 are provided with annular protrusion 2, and the side, inside and outside both sides of said annular protrusion 2 all is provided with the inclination angle; Described secondary extrusion punch 10 is made up of the truncated cone-shaped on second pedestal 9 and second pedestal 9 protruding 8.
A kind of preferred version as the utility model: the utility model also comprises secondary extrusion protection mould 7; Described secondary extrusion protection mould 7 comprises conical tube 13, and the gradient of conical tube 13 lateral surfaces is identical with the lateral surface gradient of once pushing punch 5 annular protrusions 2; The gradient of conical tube 13 medial surfaces is identical with the lateral surface gradient of secondary extrusion punch 10 truncated cone-shaped protruding 8; The end that conical tube 13 diameters are bigger is outside equipped with spacing platform 11, is provided with groove corresponding to spacing platform 11 on the die 1; Die 1 top is provided with the fixed head 12 of secondary extrusion protection mould 7 corresponding to spacing platform 11.
Further, said secondary extrusion protection mould 7 is combined by at least three mold monomers 14; Secondary extrusion protection mould 7 is set to split type, is convenient to the demoulding after blank 4 moulding.
During use, at first blank 4 is positioned in the die 1, once pushes, on blank 4, suppress a cannelure through once pushing punch 5; Take out once push punch 5 after, protect mould 7 to put into the cannelure that squeezes out the secondary extrusion after, protect mould 7 fixing secondary extrusion through fixed head 12; Can use secondary extrusion punch 10 to carry out secondary extrusion then.
