Description
Technical field
The utility model relates to steel pipe technical field of processing equipment, is specifically related to a kind of inner die for cold-drawn process lubricating arrangement.
Background technology
Steel pipe is in Cold Drawing Process, because the stressed rear mold of extruding of internal mold, external mold and steel pipe is is easily worn and torn, die life is short, and mould easy distortion generation burr in loading process, causes steel pipe to produce and draws trace, external mold produces burr and easily finds, internal mold produces burr to be caused in steel pipe outside to produce straight line drawing trace, and is difficult for being found, until pickling finished product to inspection center is while carrying out finished product detection, just can find, steel pipe is defective by the gross.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of simple in structure, can lubricate internal mold, improve the inner die for cold-drawn process lubricating arrangement of steel pipe qualification rate.
For achieving the above object, the utility model provides following technical scheme: a kind of inner die for cold-drawn process lubricating arrangement, comprise internal mold matrix, described internal mold matrix end face middle part offers screwed hole, described screwed hole internal thread is connected with screwed hole the inner described in plug and is provided with internal mold through hole, described plug middle part is provided with centre bore, the inner internal mold through hole of aiming at of described plug offers plug through hole, described internal mold matrix below is provided with base, described base upper surface is provided with the reservoir for placing cooling fluid, described reservoir is aimed at internal mold through hole, described base one end is provided with hydraulic pump, between described hydraulic pump and reservoir, be provided with pipette, described hydraulic pump and plug outer end are provided with drain pipe, described drain pipe one end and plug outer end are tightly connected, the liquid outlet of the drain pipe other end and hydraulic pump is tightly connected.
By adopting technique scheme, hydraulic pump sucks pipette by the cooling fluid in reservoir by hydraulic pump, then be delivered to centre bore through drain pipe, cooling fluid flow into internal mold through hole from plug through hole afterwards, and last cooling fluid falls into reservoir again, forms a cooling recirculation system, steel pipe reduces rapidly with the heat that the interior outer mold of drawbench produces in Cold Drawing Process, the cold-drawn speed of drawbench improves 30%, has improved 62% die life, and steel pipe produces and draws the ratio of trace to reduce by 85%.
The utility model is further set to: between described drain pipe and plug outer end, be provided with connector, drain pipe is tightly connected by connector and plug.By this setting, drain pipe is connected reliably with plug, and attended operation is convenient.
The utility model is also further set to: described internal mold through hole and the alignment of plug through hole center line, and two through hole equal diameters.By this setting, coolant flow is smooth and easy, and cooling effectiveness is high.
The utility model is also further set to: described pipette and drain pipe are rubber hose.By this setting, pipette and drain pipe long service life, cost is low.
The utility model has the advantages that: compared with prior art, the utility model structure arranges rationally, hydraulic pump sucks pipette by the cooling fluid in reservoir by hydraulic pump, then be delivered to centre bore through drain pipe, cooling fluid flow into internal mold through hole from plug through hole afterwards, last cooling fluid falls into reservoir again, form a cooling recirculation system, steel pipe reduces rapidly with the heat that the interior outer mold of drawbench produces in Cold Drawing Process, the cold-drawn speed of drawbench improves 30%, improved 62% die life, steel pipe produces and draws the ratio of trace to reduce by 85%.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
