Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of thin-wall steel tube annular groove roll forming processing method, comprises the following steps:
Step 100: thin-wall steel tube is blocked into Len req, and to thin-wall steel tube two chamfer, ensure that thin-wall steel tube length and chamfering meet the requirements.The bore of this thin-wall steel tube, pipe external diameter without the need to reprocessing, such as, are exactly fluid-link steering post outer its bore of thin-wall steel tube, the pipe external diameter of finished product.
Step 200: install roll extrusion frock:
Engine lathe is installed roll extrusion frock.As shown in accompanying drawing 1,2, roll extrusion frock comprises Mohs spacer shell 1, Mohs headstock plug 2, revolution tailstock plug 3.Mohs headstock plug 2 one end is identical with Mohs spacer shell 1 internal via shape, Mohs headstock plug 2 other end end face offers link slot 4, revolution tailstock plug 3 one end is step, first step 5 is identical with link slot 4 shape, second step 6 and the 3rd step 7 are ring-shaped step, wherein the difference in height a of the 3rd step 7 and second step 6 and thin-wall steel tube 8 need its degree of depth of annular groove 9 of roll extrusion consistent, the width b of second step 6 is consistent with thin-wall steel tube 8 needing its width of annular groove 9 of roll extrusion, consider thin-wall steel tube 8 wall thickness, this two place unanimously refers to basically identical, the diameter D1 of Mohs headstock plug 2 is identical with the annular diameter D2 of the 3rd step 7.Revolution tailstock plug 3 can be changed a social system by standard live centre and form, when turning round tailstock plug 3 and withstanding Mohs headstock plug 2, the end face that second step 6 and Mohs headstock plug 2 offer link slot 4 namely define with thin-wall steel tube 8 on need its width of annular groove 9 of roll extrusion, annular concave platform that the degree of depth is consistent, be beneficial to roll forming, and revolution tailstock plug 3 plays certain supplemental support effect.The diameter D1 of Mohs headstock plug 2 mates with the bore of the thin-wall steel tube 8 needing roll extrusion annular groove, Mohs headstock plug 2 pairs of thin-wall steel tubes 8 play a supportive role; when thin-wall steel tube 8 clamps thin-wall steel tube 8 after being set in Mohs headstock plug 2, and the support of Mohs headstock plug 2 pairs of thin-wall steel tubes 8 ensures that thin-wall steel tube 8 is not yielding.
Step 201: the scroll chuck 10 pulling down lathe, loads lathe main axis hole by Mohs spacer shell 1, Mohs spacer shell 1 plays connection driving effect;
Step 202: scroll chuck 10 loads onto lathe, packs into Mohs spacer shell 1 by Mohs headstock plug 2 through scroll chuck 10 and connects;
Step 203: revolution tailstock core 3 is contained on lathe tailstock.
Step 300: adjustment revolution tailstock plug 3 withstands Mohs headstock plug 2, the end face that the second step 6 now turning round tailstock plug 3 and Mohs headstock plug 2 offer link slot 4 namely define with thin-wall steel tube 8 on need its width of annular groove 9 of roll extrusion, annular concave platform that the degree of depth is consistent; Low rate start lathe, checks Mohs headstock plug 2, revolution tailstock plug 3, whether coaxial synchronous turns round scroll chuck 10, if turn round together, illustrate that roll extrusion frock is installed reliable.
Step 400: install rolling tool:
Step 401: milled head 11 is installed on roll extrusion knife bar 12 and forms rolling tool, resistance to pressure grease to be coated to milled head 11, the width of this milled head 11 mates with thin-wall steel tube 8 needing its width of annular groove 9 of roll extrusion, is convenient to the roll forming shape of annular groove 9 good;
Step 402: roll extrusion knife bar 12 is fixed on lathe cutter saddle, calibration rolling tool center, makes itself and machine tool chief axis axis substantially keep in the same horizontal line in X-direction.
Step 500: tool setting: adjustment lathe cutter saddle makes milled head 11 center aim at the center of second step 6 along machine Z-axis direction, i.e. the center of annular concave platform, then locks lathe cutter saddle Z-direction.
Step 600: arrange rolling speed, mainly refers to arrange machine spindle speed, requires the comparatively slow-speed of revolution, such as 110r/min.
Step 700: translation lathe tailstock exits revolution tailstock plug 3, thin-wall steel tube 8 is set in Mohs headstock plug 2, Mohs headstock plug 2 is offered on the end face of link slot 4 and thin-wall steel tube 8 needs the left side wall of the annular groove 9 of roll extrusion in the face of neat, then scroll chuck 10 is clamped thin-wall steel tube 8; Translation lathe tailstock makes revolution tailstock plug 3 return to and exits front original position, then thin-wall steel tube 8 need its position of annular groove 9 of roll extrusion consistent with annular concave platform, after revolution tailstock plug 3 returns to and exits front original position, make the gap leaving 0.5 ~ 0.8mm between thin-wall steel tube 8 tail end and revolution tailstock plug, when roll extrusion annular groove 9, be beneficial to metal deformation flow.
Step 800: start lathe, the slow feeding of lathe cutter saddle, carrys out control loop groove depth by lathe cutter saddle feeding dial.Milled head 11 rolls out annular groove 9 on thin-wall steel tube 8, namely manages interior formation boss at thin-wall steel tube 8.
