Abstract
The utility model discloses a multi-inner-cooling-hole hard alloy bar forming production device which comprises an extrusion forming mold. An inner-cooling-hole core bar is arranged in the extrusion forming mold, a mold adapter is arranged on the periphery of the extrusion forming mold, a double-body cylinder is arranged at the upper end of the extrusion forming mold, a groove is formed in the lower portion of the double-body cylinder, the extrusion forming mold and the mold adapter are clamped in the groove of the double-body cylinder, and a double-body cylinder piston is arranged on the upper portion of the double-body cylinder and fixedly connected with a hydraulic shaft. According to the multi-inner-cooling-hole hard alloy bar forming production device, a multi-inner-cooling-hole hard alloy bar can be extruded, a core part of the bar is formed by extruded materials of an inner cylinder body of the double-body cylinder, and an outer part of the bar is formed by extruded materials of an outer cylinder body of the double-body cylinder. The outer part and the core part are different in material performance, under the condition that the performance of the outer part is not reduced, materials are accordingly saved, and cost is accordingly reduced. After the inner-cooling-hole core bar of the multi-inner-cooling-hole hard alloy bar forming production device is replaced, a single-inner-cooling-hole hard alloy bar can be further manufactured.
Description
Technical field
The utility model relates to powder metallurgy manufacturing technology field, relates in particular to a kind of many interior cold hole hard alloy bar shaping process units.
Background technology
Existing hart metal product manufacturing process is mainly made up of compound preparation, shaping and three parts of sintering.Existing hart metal product is shaped and normally adopts mould compressing, packs in mould by compound, afterwards by pressurization compression powder forming up and down, then deviates from mould and finally completes compacting and form pressed compact.
Interior cold hole bar is the new high-tech product that carbide alloy field occurs in recent years, mainly contain single interior cold hole bar and the cold hole of Duo Nei bar, with the carbide drill of this bar production, slotting cutter, reamer, screw tap etc., when for processing work, there is the advantages such as good cooling results, chip removal effect is high, surface smoothness good, life tools are long.In actual use, interior cold hole bar and the cold hole of Duo Nei bar General Requirements Facing material performance are higher, and middle material capability be there is no to very high request, but current conventional shaping dies can only be produced the inside and outside the same hard alloy bar of material, entirety material used is all the material that performance is higher, causes high performance material waste.
Utility model content
For the defect of above-mentioned prior art, the utility model provides a kind of many interior cold hole hard alloy bar shaping process units, to produce outside different with internal material performance hard alloy bars, realizes material economy.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of many interior cold hole hard alloy bar shaping process units, comprise extrusion forming die, in described extrusion forming die, be provided with interior cold hole core bar, perimembranous is provided with mold adapter, the upper end of described extrusion forming die is provided with extra quality cylinder, the bottom of extra quality cylinder is provided with groove, and extrusion forming die, mold adapter are installed in the groove of extra quality cylinder; The top of described extra quality cylinder is provided with extra quality cylinder piston, on extra quality cylinder piston, is fixedly connected with hydraulic axis.
As the improvement to technique scheme, described extrusion forming die and mold adapter tight fit.
As the improvement to technique scheme, described mold adapter and extra quality cylinder are bolted to connection.
Compared with prior art, the beneficial effects of the utility model are: shaping process units of the present utility model, in the inner casing of extra quality cylinder, add the pressing materials of lower-performance material, become in the future the core of bar, in outer shell, add superior performance material pressing materials, become in the future the extra quality cylinder piston in outside descending promotion under the effect of hydraulic axis of bar, extra quality cylinder inner casing is synchronizeed with the material of outer shell and squeeze and go to extrusion forming die, at extrusion forming die internal shaping, the pressing materials of inner lower-performance material forms interior cold hole through interior cold hole core bar, make many interior cold holes bar, cold hole core bar in changing, can also make single interior cold hole bar, in many, cold hole bar is different with internal material performance with the outside of single interior cold hole bar, thereby in the situation that realizing external performance and not reducing, realize material economy, cost-saving.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, many interior cold hole hard alloy bar shaping process units of the present utility model, comprise extrusion forming die 6, in described extrusion forming die 6, be provided with interior cold hole core bar 5, perimembranous is provided with mold adapter 4, the upper end of described extrusion forming die 6 is provided with extra quality cylinder 3, and the bottom of extra quality cylinder 3 is provided with groove, and extrusion forming die 6, mold adapter 4 are installed in the groove of extra quality cylinder 3; The top of described extra quality cylinder 3 is provided with extra quality cylinder piston 2, on extra quality cylinder piston 2, is fixedly connected with hydraulic axis 1.
Described extrusion forming die 6 and mold adapter 4 tight fits.
Described mold adapter 4 is bolted to connection with extra quality cylinder 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
