Description
Technical field
The utility model relates to pressurizing unit, relates in particular to a kind of pressurizing unit of high temperature alloy pipe.
Background technology
The advantages such as high temperature alloy pipe has intensity height under the high temperature, and is anti-oxidant, anticorrosive are widely used in the industrial circles such as Aeronautics and Astronautics aircraft, generating, rocket engine, nuclear reactor, petrochemical industry.But high-temperature alloy material is because intensity is high, and material flowability is poor, the hot processing temperature narrow range, and according to existing production technology, the difficulty that often is shaped during actual high temperature alloy pipe hot extrusion is produced, the product percent defective is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the high temperature alloy pipes that a kind of universal performance is good, yield rate is high, production cost is low pressurizing unit is provided.
The utility model is achieved by the following technical solution:
The high temperature alloy pipes pressurizing unit, comprise mould bases and hot-extrusion mold, described hot-extrusion mold is installed on the mould bases, described mould bases comprises upper bolster, die shoe, guide pillars and bushes, one end of guide pin bushing is connected with upper bolster, guide pillar is connected with die shoe, and the guide pillar other end is socketed in the guide pin bushing, can move up and down along guide pin bushing; Described hot-extrusion mold comprises extrusion axis, squeezing needle, dummy block, graphite pads, recipient and extrusion die; One end of described extrusion axis is fixedly connected with upper bolster, the other end is fixedly connected with squeezing needle.
Described recipient is double-decker, comprises recipient liner and recipient outer lining; Described recipient liner is bottomless cylindrical shape, is positioned at be connected with the squeezing needle periphery of part of extrusion axis, its inner high temperature blank that is used for being contained in extrusion process; Described recipient liner outer wall connects the recipient outer lining by interference fit.
Described squeezing needle lower end is provided with 0.05 °～0.12 ° pattern draft.
The utility model compared with prior art has following beneficial effect:
The utility model is provided with the mould bases of tape guide, can be installed on the extruder, also can push at general forcing press or hydraulic press simultaneously, and versatility is good; The utility model is owing to adopted guide pillar, guide sleeve structure, and the centering of a whole set of mould is good, is difficult for off-centre during extruding, and yield rate is high, and centering is good; Hot-extrusion mold of the present utility model is installed on the mould bases, and can be according to different tubing specifications, changes extrusion die and squeezing needle, and is easy to use, flexible, efficient is high, and stock utilization is high, and cost is low.
