According to the oil tube head loose tooling, the inner die is formed by butting and splicing the two inserts, the inner die is embedded in the outer die sleeve cavity, the intermediate cavity of the inner die is provided with the cavity body recessed towards the outer side of the inner die, so that the oil tube head loose tooling with the boss can be directly forged and formed for one time, workload is reduced, efficiency is improved, materials and cost are saved, and product quality is improved.
Description
Technical field
The present invention relates to forge die field, particularly relate to a kind of tubing head loose tool with boss.
Background technology
In prior art, the flanged (FLGD) forging in two ends is generally adopted monoblock type loose tooling forging, two ends have the forging of flange and Intermediate Gray boss to be first pass through monoblock type loose tooling forging to process the flanged (FLGD) forge piece blank reheating in two ends, then pass through the boss processing centre, this will cause the waste of material, the increase of workload and inefficiency.
Summary of the invention
The technical problem to be solved is in that to provide a kind of tubing head loose tool with boss, it is possible to makes the disposable direct forging molding of the tubing head with boss, decreases workload, improve work efficiency, save material and cost.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is:
A kind of tubing head loose tool with boss, including outer die casing, internal mold, described internal mold is round table-like structure, internal mold is provided with internal mold cavity, described internal mold cavity includes epicoele, lumen and cavity of resorption, epicoele and cavity of resorption are cylindric, lumen is cylindrical-shaped structure, the diameter of epicoele and cavity of resorption is all higher than the diameter of lumen, described lumen is provided with the cavity caved in the outside of internal mold, described epicoele, lumen and cavity of resorption are in turn connected into as a whole internal mold cavity, epicoele, lumen, the axis of cavity of resorption is all located along the same line with the axis of internal mold, described internal mold is by size, two insert docking that shape is all identical with structure are put together, the cylindrical structure that described outer die casing is, outer die casing is provided with the round table-like outer die casing cavity corresponding with internal mold outer surface, the described axis of outer die casing cavity and the axis of outer die casing coincide.
Further, described epicoele is equipped with rounding with the junction of lumen and the junction of lumen and cavity of resorption.
Further, the lateral wall of described outer die casing is provided with a ring annular groove.
Further, the lateral wall of described internal mold is provided with a ring annular groove.
Further, the top of described internal mold is arranged with several lifting screwed holes, and described lifting screwed hole is symmetrically distributed in two inserts of internal mold.
Further, the cavity of described lumen is provided with two, and is symmetrically set in the both sides of lumen.
Compared with prior art, the invention has the beneficial effects as follows: owing to adopting internal mold to be put together by two insert docking that size, shape and structure are all identical, internal mold is embedded in outer die casing cavity, the lumen of internal mold is provided with the cavity caved in the outside of internal mold, the disposable direct forging molding of the tubing head with boss can be made, decrease workload, improve work efficiency, save material and cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further details:
nullAs shown in Figures 2 and 3，A kind of tubing head loose tool with boss，Including outer die casing 1、Internal mold 2，Described internal mold 2 is round table-like structure，Internal mold 2 is provided with internal mold cavity 20，Described internal mold cavity 20 includes epicoele 21、Lumen 22 and cavity of resorption 23，Epicoele 21 and cavity of resorption 23 are cylindric，Lumen 22 is cylindrical-shaped structure，The diameter of epicoele 21 and cavity of resorption 23 is all higher than the diameter of lumen 22，Described lumen 22 is provided with the cavity 221 caved in the outside of internal mold 2，Described epicoele 21、Lumen 22 and cavity of resorption 23 are in turn connected into as a whole internal mold cavity 20，Epicoele 21、Lumen 22、The axis of cavity of resorption 23 is all located along the same line with the axis of internal mold 2，Described internal mold 2 is by size、Two insert docking that shape is all identical with structure are put together，The cylindrical structure that described outer die casing 1 is，Outer die casing 1 is provided with the round table-like outer die casing cavity corresponding with internal mold 2 outer surface，The axis of described outer die casing cavity and the axis of outer die casing 1 coincide.Described epicoele 21 is equipped with rounding with the junction of lumen 22 and the junction of lumen 22 and cavity of resorption 23.The lateral wall of described outer die casing 1 is provided with a ring annular groove 11.The lateral wall of described internal mold 2 is provided with a ring annular groove 24.As it is shown in figure 1, the top of described internal mold 2 is arranged with several lifting screwed holes 25, described lifting screwed hole 25 is symmetrically distributed in two inserts of internal mold 2.As in figure 2 it is shown, the cavity 221 of described lumen 22 is provided with two, and it is symmetrically set in the both sides of lumen 22.
