The utlity model has following advantage: the quincunx steel pipe of seamless five lobe of producing with this mould cold-drawn, by to pipe finish draw, pull out, extension processes at one time, steel pipe circumferential surface has five helixes, by the control to spiral angle, the restriction of shaping channel length and the import outlet cross sectional dimensions ratio that the size of face is answered in contrast crosswise, in same size situation by the product of producing is detected, the quincunx steel tube performance of seamless five lobe of producing is good, hot strength, torsional strength and case hardness are all good than the common quincunx steel pipe of seamless five lobe, in as building trade and national defence, need not be in the quincunx steel pipe of seamless five lobe fill concrete, cost is low, easy to use.
Specifically, described discharge opening 2 is round table-like hole, and the diameter of described discharge opening 2 is from die ontology 1 surface to being descendingly to successively decrease gradually near outlet one end of 4, and discharge opening is that round table-like hole object is that the product that guarantees is out tubing; Described discharge opening 2 is connected to the five quincunx holes 6 of lobe of 2 ends of discharge opening circle in being provided with near the one end that exports 4, the five described quincunx holes 6 of lobe are that ratio is amplified relation with outlet 4 cross sections, the five described quincunx holes 6 of lobe with outlet 4 between slope be connected, product out can have extruding to mould inner wall from exporting 4, and product evenly so neither can squeeze the helical surface of hindering shaping channel to the extruding force of five lobe plum blossom holes again can be because of not inhomogeneous and be out of shape to the extruding force of mould inner wall.Facilitate raw material pipe to insert in mould; Described charging hole 7 is provided with for being fixed on the stepped hole 8 on cold-draw equipment away from one end of shaping channel 3, and described stepped hole 8 is located along the same line with the axis of shaping channel 3, facilitates fixed mould, makes to produce more stable; Described charging hole 7 is the five quincunx holes of lobe that are connected with import 5 slopes, charging hole plays distortion cushioning effect, pipe distortion is changed can be too not fast, affect the quality of production, simple in structure, can meet the requirement that raw material pipe is deformed into rectangular tube, but can not be circular, circle does not have cushioning effect, large because steel pipe is deformed to the quincunx distortion of five lobes from circle.
Specifically, this mould is fixed on that cold-draw equipment produces above, namely the disclosed equipment for the production of screw rotor is gone up at National IP Network station, application number is 2011101857723, when producing, this mould is fixed on equipment, mould is circumferentially limited in and rotates in pipe, and rotate pipe, be rotatably assorted in mold base, first, raw material pipe one end is struck more carefully, this end is passed to this mould, clamp on pulling device will be clamped pipe, then draw pipe and do translational motion, due to mould and rotation pipe axial limiting, rotating pipe racks moving mold rotates, because mould rotates when working, pipe when work be only mobile does not rotate naturally pipe just to have become cross section is that rectangular steel tube and rectangular steel tube outer surface can form certain helical duct, therefore, during work, mold rotation, pipe is through mould translation, both combinations, pipe has just become the seamless rectangular steel tube that outer surface has spirality channel.In fact, in shaping channel 3, previous section is just pipe distortion transition in fact, and that section that shaping channel 3 is last 3 millimeters is only the forming dimension of product, namely finally sizing.
The product produced with this mould and the common quincunx steel tube performance parameter comparison of seamless five lobe below, the length of shaping channel is 26mm, the angle of the helix of described shaping channel 3 from import 5 to outlet 4 rotations is 8.6 °, and described import 5 outlet that the size of face is answered in contrast crosswise 4 cross sectional dimensions are than being 1.31:1.
Raw material are product and the quincunx steel pipe parameter comparison of common seamless five lobe that pipe diameter 250mm thickness 5mm works it out
Raw material are product and the common seamless rectangular steel tube parameter comparison that pipe diameter 160mm thickness 5mm works it out
Raw material are product and the common seamless rectangular steel tube parameter comparison that pipe diameter 90mm thickness 5mm works it out
From above table, can find out, the quincunx steel pipe of seamless five lobe that the utility model is produced is than the common quincunx steel pipe hot strength of seamless five lobe, case hardness, it is high that torsional strength and yield point are all wanted, the properties of product that explanation is produced with the utility model are better than former, especially torsional strength is than at least many in the past 200Mpa, hot strength height nearly one times, performance is better than the common quincunx steel pipe of seamless five lobe far away, applicable like this occasion is a lot, because the quincunx steel pipe of seamless five lobe has lightweight feature, add good mechanical performance, applied widely.
With regard to the utility model preferred embodiment, be described above, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change, and all various variations of doing in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
