Description

Thin-wall high temperature alloy pipe pressurizing unit
Technical field
The utility model relates to pressurizing unit, relates in particular to a kind of pressurizing unit of thin-wall high temperature alloy tubing.
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 thin-wall high temperature alloy pipe 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:
Thin-wall high temperature alloy pipe 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 extrusion axis is multidiameter, is divided into multidiameter upper end and multidiameter lower end, and described multidiameter upper end is fixedly connected with upper bolster, and described multidiameter lower end is fixedly connected with squeezing needle.
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.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Sequence number among the figure: 1, upper bolster, 2, die shoe, 3, guide pillar, 4, guide pin bushing, 5, extrusion axis, 6, squeezing needle, 7, dummy block, 8, graphite pads, 9, recipient, 10, extrusion die, 11, the multidiameter upper end, 12, the multidiameter lower end.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
According to shown in Figure 1, a kind of thin-wall high temperature alloy pipe of the utility model 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 1, die shoe 2, guide pillar 3 and guide pin bushing 4, and an end of guide pin bushing 4 is connected with upper bolster 1, and guide pillar 3 is connected with die shoe 2, guide pillar 3 other ends are socketed in the guide pin bushing 4, can move up and down along guide pin bushing 4; Described hot-extrusion mold comprises extrusion axis 5, squeezing needle 6, dummy block 7, graphite pads 8, recipient 9 and extrusion die 10; One end of described extrusion axis 5 is fixedly connected with upper bolster 1, the other end is fixedly connected with squeezing needle 6; Described extrusion axis 5 is multidiameter, be divided into multidiameter upper end 11 and multidiameter lower end 12, described multidiameter upper end 11 is fixedly connected with upper bolster 1, described multidiameter lower end 12 is threaded with squeezing needle 6, in extrusion process, squeezing needle 6 bears HTHP, if squeezing needle 6 damages, the design that is threaded connection can conveniently be changed squeezing needle 6; Described squeezing needle 6 lower ends are provided with 0.05 °~0.12 ° pattern draft, the very easily demoulding.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
