Abstract

The utility model relates to the finish forging die for manufacturing oxygen lance nozzles. The utility model is characterized in that the utility model adopts the top and the bottom finish forging dies and a cover die, the metallic materials which are used for preparing the oxygen lance nozzle are put into a rough forging die and are forged primitively after heated. After the metallic materials are taken out, the metallic materials are put into the finish forging die and are carried out with the finish forging extrusion forming. The die of the utility model can deduct the mechanical processing procedure which is time-consumed and material-consumed, Production quality can be warranted, and production efficiency can be increased.

Description

Forging die of an oxygen lance nozzle

The utility model belongs to the instrument of metal forging shaping usefulness.

The general technology of making the oxygen gun sprayer product is with after the metal material process blanking of preparation oxygen gun sprayer, the heating, forges into the blank of convex shape, and then carries out processing of car pin and deep processing with plant equipment.Adopt the not only living rate of production and marketing of this technology low, and in process, also will waste the metal material of 60-65%.Because oxygen gun sprayer is the necessary apparatus of STEELMAKING PRODUCTION, the amount that not only needs is big, and the amount of Xiao Haoing is also very big simultaneously, in order to guarantee STEELMAKING PRODUCTION, need to drop into great amount of manpower and material resources, financial resources and equipment and process oxygen gun sprayer, this brings utmost point adverse influence to STEELMAKING PRODUCTION.

The utility model is according to following characteristics that oxygen gun sprayer possessed: (1) whole oxygen gun sprayer does not require to possess higher processing precision; (2) because used metal material is pure red copper, so very high thermoplasticity is arranged; (3) institutional framework closely and have certain fineness etc., for the preparation oxygen gun sprayer provides a kind of hot extrusion forging die mould of precision, to overcome deficiencies such as processed complex that prior art exists, time-consuming, expense material.

The utility model is made of mold and bed die, its design feature is that the angle R with round platform position (7) in the patrix dwindles 1-3 °, the best is 1 °, and the center O of tank (6) moved to O ', so that the deviating from of patrix, in addition, in order accurately to make the center of mould, also is furnished with a cover die (2) in the outside of finish forge mould.The metal material of manufacturing shower nozzle just can be produced qualified oxygen gun sprayer after through first forging dies, the extruding of smart forging dies, boring deep processing.

Compare with prior art, make shower nozzle with this mould and have the following advantages:

1, this mould is applicable to the round copper product of φ 60-φ 70mm, so enlarged the materials specification limit, improves the utilization rate of material, thereby can save the metal material of 60-65%;

2, owing to reduced complicated machining processes, productivity ratio is improved;

3, can obtain rational metal streamline and distribute, the forging ' s block dimension precision is improved, thereby improve the quality and the bearing capacity of forging.

Accompanying drawing has provided concrete structure of the present utility model, and the utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the patrix profile of finish forge mould;

Fig. 2 is the counterdie profile of finish forge mould;

Fig. 3 is the constitutional diagram of finish forge mould;

Fig. 4 is the product master drawing of five hole oxygen gun sprayers.

The utility model comprises patrix (1), counterdie (3) and the cover die (2) of precision forging die, the angle R of round platform position (7) in the patrix is dwindled 1 °, and the center of tank (6) is moved to O ' by O, so that the deviating from of patrix.

The red copper of making the metal material φ 65mm of oxygen gun sprayer is put into forging mould just through blanking and after heating, take out forging stock just after carrying out just forging with the above pneumatic hammer of 75Kg; Precision forging die counterdie (3) is put into cover die (2), first forging stock is carried out post bake (temperature is 250 ℃), after big first end put into the counterdie of precision forging die, the patrix (1) of precision forging die of closing forges, after upper die and lower die are deviate from cooling, to the deep processing of holing of finish forge spare, promptly obtain qualified oxygen gun sprayer.

Claims

1, a kind of mould that is used to forge five hole oxygen gun sprayers is made of upper die and lower die, it is characterized in that it also comprises a cover die (2), and dwindles the angle R at round platform position (7) in the patrix, with the center of tank (6) by 0 move to 0 '.

2, mould according to claim 1 is characterized in that the angle R at round platform position in the patrix should dwindle the 1-3 degree, and the best is 1 degree.
