Beneficial effect: compared with prior art, advantage of the present invention is by carry out the method for roll extrusion from the thin-wall steel tube outside, thin-wall steel tube is processed annular groove, make and form boss in the pipe, in order to the parts of installing in the stationary pipes, guarantee simultaneously being of the required size of annular groove of required roll extrusion with special roll extrusion frock, greatly improved production and processing efficient, save material, reduced manufacturing cost.
Description of drawings
Fig. 1 is roll extrusion frock of the present invention and uses schematic diagram;
Fig. 2 is the partial enlarged view I of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, a kind of thin-wall steel tube annular groove roll forming processing method may further comprise the steps:
Step 100: thin-wall steel tube is blocked into Len req, and to thin-wall steel tube two chamfers, guarantee that thin-wall steel tube length and chamfering meet the requirements.The bore of this thin-wall steel tube, pipe external diameter need not reprocessing, for example are exactly outer its bore of thin-wall steel tube of fluid-link steering post, the pipe external diameter of finished product.
Step 200: the roll extrusion frock is installed:
At engine lathe the roll extrusion frock is installed.Shown in accompanying drawing 1,2, the roll extrusion frock comprises Mohs spacer shell 1, Mohs headstock plug 2, revolution tailstock plug 3.Mohs headstock plug 2 one ends are identical with Mohs spacer shell 1 interior hole shape, Mohs headstock plug 2 other end end faces are offered link slot 4, revolution tailstock plug 3 one ends are step, first step 5 is identical with link slot 4 shapes, second step 6 and the 3rd step 7 are ring-shaped step, wherein need annular groove 9 its degree of depth of roll extrusion consistent on the difference in height a of the 3rd step 7 and second step 6 and the thin-wall steel tube 8, need annular groove 9 its width of roll extrusion consistent on the width b of second step 6 and the thin-wall steel tube 8, consider thin-wall steel tube 8 wall thickness, this two place unanimously refers to basically identical, and 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 formed by the transformation of the way of standard live centre, when revolution tailstock plug 3 withstands Mohs headstock plug 2, the end face that second step 6 and Mohs headstock plug 2 are offered link slot 4 namely formed with thin-wall steel tube 8 on need annular groove 9 its width of roll extrusion, the 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 that needs the roll extrusion annular groove, 2 pairs of thin-wall steel tubes 8 of Mohs headstock plug play a supportive role; thin-wall steel tube 8 is set in when Mohs headstock plug 2 is rear to be clamped thin-wall steel tube 8, and the support of 2 pairs of thin-wall steel tubes 8 of Mohs headstock plug guarantees that thin-wall steel tube 8 is not yielding.
Step 201: pull down the scroll chuck 10 of lathe, with the Mohs spacer shell 1 lathe main axis hole of packing into, Mohs spacer shell 1 works the driving effect that connects;
Step 202: scroll chuck 10 is loaded onto lathe, Mohs headstock plug 2 is passed scroll chuck 10 pack into 1 connection of Mohs spacer shell;
Step 203: will turn round tailstock core 3 and be contained on the lathe tailstock.
Step 300: adjust revolution tailstock plug 3 and withstand Mohs headstock plug 2, the end face that the second step 6 that turns round tailstock plug 3 this moment and Mohs headstock plug 2 are offered link slot 4 namely formed with thin-wall steel tube 8 on need annular groove 9 its width of roll extrusion, the annular concave platform that the degree of depth is consistent; The low rate start lathe checks whether coaxial synchronous revolution of Mohs headstock plug 2, revolution tailstock plug 3, scroll chuck 10, if this this turn round together, illustrate that the roll extrusion frock installs reliably.
Step 400: rolling tool is installed:
Step 401: milled head 11 is installed on the roll extrusion knife bar 12 and consists of rolling tool, to coat withstand voltage lubricating grease to milled head 11, need annular groove 9 its width couplings of roll extrusion on the width of this milled head 11 and the thin-wall steel tube 8, be convenient to the roll forming shape of annular groove 9 good;
Step 402: roll extrusion knife bar 12 is fixed in lathe cutter saddle, and 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: adjust lathe cutter saddle and make milled head 11 centers aim at the center of second step 6 along the lathe Z-direction, namely then lock the lathe cutter saddle Z-direction at the center of annular concave platform.
Step 600: rolling speed is set, mainly refers to arrange require machine spindle speed than the slow-speed of revolution, such as 110r/min.
Step 700: the translation lathe tailstock withdraws from revolution tailstock plug 3, thin-wall steel tube 8 is set in Mohs headstock plug 2, make left side wall that Mohs headstock plug 2 offers the annular groove 9 that needs roll extrusion on the end face of link slot 4 and the thin-wall steel tube 8 in the face of neat, then scroll chuck 10 is clamped thin-wall steel tubes 8; The translation lathe tailstock returns to revolution tailstock plug 3 and withdraws from front original position, then need annular groove 9 its positions of roll extrusion consistent with annular concave platform on the thin-wall steel tube 8, after revolution tailstock plug 3 returns to and withdraws from front original position, make the gap of leaving 0.5～0.8mm between thin-wall steel tube 8 tail ends and the 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 comes the control loop groove depth by lathe cutter saddle feeding dial.Milled head 11 rolls out annular groove 9 at thin-wall steel tube 8, namely forms boss in thin-wall steel tube 8 pipes.
