Abstract
The utility model relates to a pipe end sizing die set, including main hydraulic cylinder and the mould piece is connected with main hydraulic cylinder, footpath decided at the higher level but not officially announced mould and outer sizing mould be equipped with in the mould piece, be connected with the cylinder that drives its reciprocating motion, characterized in that on one side of the outer sizing mould: it has the dead slot that is used for placing interior sizing mould and outer sizing mould to make in the mould piece, and the spring is equipped with respectively to bottom surface and two sides that correspond interior sizing mould and outer sizing mould of mould piece, and interior sizing mould is put into in the dead slot of mould piece with outer sizing mould to through spring and the contact of mould piece medial surface, the rigid coupling has the slide on two outsides of mould piece respectively, and the slide passes through the copper sheathing movable fit and is connected with the pull rod. The advantage is: the problem of the pipe end chamfered edge is solved, pipe end sizing quality has been improved, still can make need to decide internal diameter and external diameter need not to change again mould, improvement machining efficiency with the specification steel pipe.
Description
Technical field
The utility model belongs to metal tube pipe end sizing apparatus field, particularly relates to a kind of tube end sizing die device.
Background technology
Tube end sizing mould to be mainly used in steel pipe car silk process, under the prerequisite not affecting its performance, steel pipe tail end diameter being carried out suitable change, to improve the car yarn quality of steel pipe, reaching standard-required.Sizing die is most important parts in tube end sizing machine equipment, and it directly decides the sizing quality of steel pipe internal-and external diameter.Sizing die in existing equipment is fixedly connected on the cylinder head of main hydraulic cylinder by 12 bolts and contiguous block, needs to change sizing die in time often criticizing after steel pipe carries out sizing.Aforementioned structure is troublesome poeration not only, and when carrying out sizing in steel pipe, because the die length of interior sizing is longer, easily occurs joining seam phenomenon during sizing, makes steel pipe inner wall produce chamfered edge, affects plug effect.
Summary of the invention
The utility model provides a kind of and increases substantially tube end sizing quality and working (machining) efficiency and tube end sizing die device easy and simple to handle for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Tube end sizing die device, the mold block comprising main hydraulic cylinder and be connected with main hydraulic cylinder, interior sizing die and outer sizing die are housed in mold block, described outer sizing die side is connected with and drives its cylinder moved back and forth, it is characterized in that: in described mold block, be shaped with the dead slot for placing interior sizing die and outer sizing die, in the bottom surface of described mold block and correspondence, spring is equipped with respectively in two sides of sizing die and outer sizing die, described interior sizing die and outer sizing die are inserted in the dead slot of mold block, and contact with mold block medial surface respectively by spring, slide is connected with on outside described mold block two, built with copper sheathing, also dynamic cooperation is connected with pull bar described slide.
The utility model can also adopt following technical scheme:
Described mold block is shaped with multiple screwed hole perpendicular to the one side at sizing center, and is connected with the cylinder head contiguous block of main hydraulic cylinder by screwed hole.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, namely respectively spring is housed by two sides of sizing die and outer sizing die in the bottom surface and correspondence of mold block, when sizing die works, spring can make mould be in automatic floating look in state, the situation that the center of steel pipe and main hydraulic cylinder is inconsistent can be compensated.By coordinating of slide and pull bar, no matter mold block moves much distances, all can prevent joining seam phenomenon, solves pipe end chamfered edge problem, and then improves tube end sizing quality.In addition, the same specification steel pipe adopting the utility model also can make to need to determine internal diameter and external diameter, without the need to more mold exchange again, eliminates the trouble of more mold exchange, improves working (machining) efficiency.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, tube end sizing die device, the mold block 2 comprising main hydraulic cylinder 9 and be connected with main hydraulic cylinder, interior sizing die 5 and outer sizing die 4 are housed in mold block, described outer sizing die side is connected with and drives its cylinder 1 moved back and forth.The dead slot for placing interior sizing die and outer sizing die is shaped with in described mold block, in the bottom surface of described mold block and correspondence, two sides of sizing die and outer sizing die are equipped with spring 3 respectively, described interior sizing die and outer sizing die are inserted in dead slot corresponding to mold block, and contact with mold block medial surface respectively by spring, the bottom surface of mold block and two sides are withstood respectively by a spring 3.Be connected with slide 7 on outside described mold block two, built with copper sheathing, also dynamic cooperation is connected with pull bar 8 described slide, and described pull bar 8 upper end is connected with fuselage, and described mold block is in the enterprising line slip of the pull bar of pipe end sizing mill.
In the present embodiment, described mold block is shaped with multiple screwed hole perpendicular to the one side at sizing center, and is connected with the cylinder head contiguous block 6 of main hydraulic cylinder 9 by screwed hole.
Operation principle of the present utility model is:
When using outer sizing die, main hydraulic cylinder certain stroke that stretches can carry out the outer sizing of pipe end; When using interior sizing die, because the top of outer sizing die is provided with cylinder, only outer sizing die need be sling by cylinder, the interior sizing of pipe end can be carried out.Because mold block is processed with 6 screwed holes perpendicular to the one side at sizing center, be connected with cylinder head contiguous block by bolt during work.Piston rod in order to avoid main hydraulic cylinder stretches out long generation and bends, and mold block two sides are welded with slide, and during work, slide can slide on pull bar, prevents the bending of main hydraulic cylinder piston rod.
The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
