Abstract
A symmetrical-wheel spinning tool comprises a locating shaft, a cross beam, vertical beams, four supports and spinning wheels. The locating shaft is installed in a locating shaft installation hole in the symmetry centre of the length direction of the cross beam. Four sets of vertical beam installation holes penetrating through the cross beam are located at in the two ends of the cross beam and arranged on the two sides of the locating shaft installation hole respectively. One ends of the four vertical beams are installed on the cross beam in a sleeved mode. When the vertical beams are installed, the distance between every two vertical beams is adjusted by selecting different installation holes in the four sets of vertical beam installation holes in the cross beam, and therefore the requirement for machining work pieces is met. One end of each support is installed in a support installation hole in the corresponding vertical beam, and the other end of each support is provided with one spinning wheel. When the symmetrical-wheel spinning tool is used for machining, as the deformation area of the work pieces has the symmetry, the residual stress state of the work pieces is improved obviously, and the shape and size accuracy of tubular parts are high. The symmetrical-wheel spinning tool has the advantages of being simple in structure, reliable in contact, easy to machine and low in cost.
Description
Technical field
The present invention relates to spinning manufacturing, specifically a kind of be installed on vertical lathe to wheel spinning tool.
Background technology
Entering fast space is large-sized solid boost motor or the core level rocket solid engine manufacturing technology and an important directions applying the Manufacturing Technology Development that has become China's solid rocket motor case and metalwork of object.China's continental rise, sky are penetrated solid vehicle rocket in the research initial stage, and take following " manned moon landing " task as traction, and the demonstration research of heavy launcher solid boost motor is at the early-stage.
Along with the fast development to space probation, need to adopt ultra-large type rocket booster.Φ 2500mm is with the most of process that adopts machining, the weldering of plate volume, has mould mould pressing of interior cylinder at present.But the cylinder for Φ 2500mm and above diameter, the forming process that can select is just very few; the forming technology of thin cylinder not only will be considered realizability and the cost control of technique, also will take into account the quality of rocket engine than requirements such as Properties Control simultaneously.
The at present domestic thin cylinder forming technology the most often adopting is mainly to have mould mould pressing, has mould rotary pressure technology to be conventionally applied to the rotary pressing processing of minor diameter cylindrical member, slender rectangular tube series products.Along with developing rapidly and demand for development to high thrust boost motor rocket of space technology, the domestic demand for large diameter and thin wall cylinder is also more and more urgent, but be greater than more than Φ 2500mm cylinder for diameter, adopts traditional obviously difficulty very of mould spinning process that has.Without " to the wheel spinning " of core, technique can effectively address this problem in employing, and there is flexible processing, frock is simple and forming accuracy advantages of higher.
Germany MT (MAN Technologie) joint-stock company proposes the earliest to wheel spinning principle, and has carried out system research.Within 1991, the said firm entrusts the Di Sen mechanical engineering company that is positioned at Dortmund, Germany to be responsible for building the vertical to wheel spinning machine of European maximum, has been successfully applied in the manufacture of European Space Agency's Ariane 5 rocket booster housing.But have nothing to do in the report with this vertical frock that wheel spinning machine is coordinated.
Summary of the invention
For overcoming the deficiency to wheel spinning tool technological gap existing in prior art, the present invention proposes a kind of to wheel spinning tool.
The present invention includes locating shaft, crossbeam, vertical beam, support and spinning roller.Locating shaft is arranged in the locating shaft installing hole at crossbeam length direction symmetrical centre place.Four groups of vertical beam installing holes that connect crossbeams lay respectively at the two ends of crossbeam and the both sides of locating shaft installing hole, and the center line of described four groups of vertical beam installing holes is all perpendicular to the side surface of this crossbeam.One end of four vertical beams is set on crossbeam, and is separately fixed at the two ends of described crossbeam and the both sides of locating shaft installing hole.When vertical beam is installed, by different installing hole in four groups of vertical beam installing holes on selection crossbeam, to regulate the spacing between described vertical beam, thereby meet the needs of processing work.One end of four supports is arranged on respectively in the support installing hole on vertical beam, and the other end of described support is separately installed with spinning roller.
The connecting hole coordinating with crossbeam that has perforation in one end of described vertical beam, the other end has the support installing hole of perforation.The described connecting hole at vertical beam two ends and the same surface that support installing hole is all positioned at this vertical beam of laying respectively at.
During use, first the cylindrical member blank that machine is added reinforcing ring is installed on workbench, adjust blank and be positioned at workbench center, according to the diameter of processed cylindrical member, by bolt, vertical beam is moved to the position near cylindrical member blank, wherein spinning roller is apart from blank 2～3cm, four vertical beams be symmetric and spinning roller on unified horizontal line.Regulate dog screw, support is moved radially along cylindrical member blank in installing hole, the cylindrical member blank reinforcing ring that spinning roller is arranged in process before test.
Rotary pressing processing, spinning roller is along with lathe longitudinal rail is along machine spindle direction to working table movement, the axial force producing and radial load acting in conjunction are on blank, and blank flows to the direction that deviates from workbench along vertical beam after attenuate, thereby realize cylindrical member the reverse spinning of wheel spinning is tested.
For solving, realize on the basis of existing technology the test of wheel spinning, the present invention's foundation is to wheel spinning principle, proposed a kind of be installed on vertical lathe to wheel spinning tool, can on vertical lathe, realize cylindrical member to wheel spinning, the surfaces externally and internally of cylindrical member blank is carried out to plastic working simultaneously, saved greatly the cost being produced by core manufacture, avoided the scuffing of spinning part and mandrel surface simultaneously, therefore spinning part presentation quality is good, and wall thickness is even; Improved cylindrical member surfaces externally and internally quality.Realize at home for the first time the test of wheel spinning, for follow-up study provides testing equipment to wheel spinning process simultaneously.That the present invention has is simple in structure, contact reliable, easily processing, feature that cost is low.
Evidence, the present invention has the following advantages:
1. the process that adopts surfaces externally and internally simultaneously to process effectively raises the surfaces externally and internally precision of cylindrical member.
2. principle is simple, and cost of raw and processed materials, Fixture Design manufacturing expense, equipment operating cost are low, handling ease, and production cost is low.
3. use existing lathe equipments, conventional core mold is replaced by spinning roller, saved the manufacture of core and administrative expenses (account for totle drilling cost 20%), do not need to install core, effectively reduce labor strength simultaneously.
4. rely on material plasticity distortion, the longitudinal seam of volume weldering cylindrical member is strengthened, greatly improved the mechanical performance of longitudinal seam, effectively raise the safety and reliability of cylindrical member.
5. because deformed area has symmetry, thus make workpiece residual stress state be improved significantly, cylindrical member form and dimensional precision is higher.
