Two, background technology:
Common vertical Ring Rolling Machine (staving press) is a kind of time-honored swaging equipment, be widely used in the Plastic Forming of rings such as bearing inner and outer ring, wheel rim, railway rim, the core roller that its main roll milling wheel and passive belt by the Motor Drive rotation change forms a pair roller, rolling to the circulation that the ring blank that is enclosed within on the core roller goes round and begins again, external diameter expansion in the ring, wall thickness reduction and progressively be shaped, the Propelling wheel on this movement roller right side props up ring makes the operation of rolling steady, the signal wheel control ring outside dimension in core roller left side.It is applicable to that profile is simple, reaming bigger ring production frequently, but to reaming than bigger ring, because of Propelling wheel maintains static in forming process, diffuse into to a certain degree after, adjust the Propelling wheel position, need to ring implement once more in addition heating for multiple times rolling.To complex contour and roll over to expand that (especially profile has the ring of dark groove than circlet spare again, as bilateral flange, duplicate gear and bilateral thrust wheel, the connectors of all kinds of ball valves etc.) common Ring Rolling Machine is powerless, (patent No.: ZL99239969.6) being exactly should this demand and occur for the multi-point radial rivet bucker, it is after the ring internal diameter expands periphery and three roll milling wheels to and all touches, continue to exert pressure, it is when restriction ring internal diameter enlarges, metal to the ring periphery is rotated backward extrusion, make it be full of mold cavity, can make and roll over the ring shaping of expanding than very little and complex contour.Be the conveniently assemble and disassemble workpiece, the lever that the little roll milling wheel of both sides needs to promote by stingy (oil) cylinder enters or leaves the operating position around the fulcrum rotation.Though the multi-point radial rivet bucker is successfully used to produce the special ring of this class, enlarged the function of common Ring Rolling Machine, the ring that common Ring Rolling Machine can't be finished is shaped, but the problem that exists is: the suitable ring size range of machine is limited, and when changing the ring kind, adjustment equipment is not too easy.
Three, summary of the invention:
Multifunctional ring rolling machine purpose of the present invention provides a kind of novel Ring Rolling Machine, and it has the basic function of common Ring Rolling Machine and multi-point radial rivet bucker concurrently, be suitable for the ring of big and different spreadings ratios of ring size range or complex contour, and equipment is operated, adjusts easy.
Multifunctional ring rolling machine has kept primary structures such as the lathe bed of common vertical Ring Rolling Machine (staving press), main roll milling wheel and core roller, but installation, adjustment and the control method of Propelling wheel and signal wheel (we claim that they are left and right two little roll milling wheels) have been done bigger variation.It is provided with the lever 12 of basic symmetric arrangement in the both sides of core roller 6, laying two little roll milling wheels 13 that structure is identical on the prong of lever, one end of lever links to each other with lever hinge 7 on being fixed on lathe bed, the other end links to each other with the piston rod of the earrings formula oil cylinder 14 that can contend with master cylinder, the earrings of the cylinder body afterbody of oil cylinder 14 then links to each other with hinge 15 on the lathe bed, oil cylinder 14 promotes lever 12 and all rotates around lever hinge 7 with little roll milling wheel 13 mounted thereto, track (near angle with rational) with big camber line enters or leaves the operating position, and the operating position of little roll milling wheel 13 is fixed on adjustment nut 9 on the lathe bed and last by projection on the lever 12 10 and projection 10 both sides, under adjust screw rod 8,11 set or adjust.
An outlet controlling the three position four-way directional control valve 18 of oil cylinder 14 motions communicates with the big chamber of oil cylinder 14 by hydraulic control one-way valve 17, and another outlet is led to the loculus of oil cylinder 14 and linked to each other with the control mouth of hydraulic control one-way valve 17.Control reversal valve 18, the pressure oil forward backs down the big chamber that hydraulic control one-way valve 17 enters oil cylinder 14, till the projection 10 that piston rod is shifted little roll milling wheel 13 onto lever contacts down when adjusting screw rod 11 (entering the operating position of setting), after reversal valve 18 commutations, pressure oil leads to the loculus of oil cylinder 14 and the control mouth of hydraulic control one-way valve 17, reverse opening hydraulic control one-way valve 17 refluxes the oil in the big chamber of oil cylinder, and the piston rod of oil cylinder 14 drives little roll milling wheel 13 and retreats, till projection 10 contacts upward adjustment screw 8.Reversal valve 18 is in meta and then locks it.
The multifunctional ring rolling machine working mechanism is as follows:
When (1) being used as common Ring Rolling Machine, after the lever 12 that promotes both sides with the oil cylinder 14 of both sides will left and right two little roll milling wheels 13 (being that signal is taken turns and Propelling wheel) be adjusted to the operating position, with the upper and lower adjustment screw rod 8 on both sides and 11 projection 10 of the lever 12 of both sides is clamped respectively again, the lever 12 that makes both sides is together with little roll milling wheel 13 location that are installed on its prong, and after this oil cylinder 14 of both sides no longer participates in work.Red-hot ring blank 5 is enclosed within on the core roller 6, control reversal valve 16, be installed in the main roll milling wheel 4 that drives rotation by motor-reduction box-power transmission shaft on slide block 3 and the guide rail 2 in that the promotion of master cylinder 1 is descending when exerting pressure, main roll milling wheel drive that ring blank 5 rotates and and core roller 6 continuous rolling that roll goes round and begins again to ring 5 that partners, ring 5 is down collaborative the Propelling wheel on right side, hole enlargement is when the ring external diameter contacts the signal wheel in left side reposefully, reversal valve 16 commutations, main roll milling wheel returns to original position, unload workpiece, finish and roll over the ring operation.
(2) when the reaming of ring is very bigger than (after being spreading with spreading before the ratio of ring internal diameter); the preferable operating position of thrust roller should retreat with the expansion of ring diameter; present vertical Ring Rolling Machine could be adjusted after need shutting down because of the thrust roller; have to carry out once more or the machine system of rolling on the heating for multiple times ring, cost increases, efficient is low.Use its course of work of multifunctional ring rolling machine as follows: with right side small oil tank 14 Propelling wheel 13 is transferred to the position of ring than minor diameter, and by the right side adjust down screw rod 11 with lever 12 and on Propelling wheel locate; Again Propelling wheel is transferred to the finished diameter position, and by right side upward adjustment screw 8 with lever 12 and on Propelling wheel 13 location.The left-side signal wheel then is positioned on the forged piece position.When starting working; after small oil tank 14 is pushed into less diametrical position with thrust roller 13; reversal valve 18 is placed the meta of locking; hydraulic control one-way valve 17 on the small oil tank 14 big chamber oil circuits has been sealed the loop; withstanding Propelling wheel because of the fluid volume is incompressible does not make it retreat; after reaming is arrived to a certain degree; controlling reversal valve 18 makes small oil tank 14 loculus oil-feeds and backs down hydraulic control one-way valve 17 and make Propelling wheel 13 retreat into reposition; the spreading of going again (or is provided with self-regulating damping in the oil return path; the limit flanging is expanded the limit and is moved back); until falling back on the position (lever plush copper 10 contacts upward adjustment screw 8) that finished product ring size is set; finish and roll over till the ring operation; like this, reaming need not shut down adjustment than big common ring, is expected a fire and once finishes.
(3) when the ring of processing reaming than very little and complex contour (dark groove is particularly arranged), common milling ring technological process and equipment are powerless to this, and at this moment, multifunctional ring rolling machine has had both the function of multi-point radial rivet bucker because of it, can be shaped easily.Its course of work is as follows: the operating position of left and right two little roll milling wheels 13 being delivered to finished size with both sides small oil tank 14, the following adjustment screw rod 11 of adjustment both sides makes it contact respectively with the plush copper 10 of both sides lever 12 and locatees, and the upward adjustment screw 8 of both sides is unclamped away from lever plush copper 10.Control two reversal valves during operation earlier, with two little roll milling wheels 13 retreat leave the operating position after, after red-hot ring base 5 is inserted in core roller 6, promoting lever 12 again makes two little roll milling wheels 13 enter the operating position, and place meta to make the oil circuit locking two reversal valves 18, after this falling 4 pairs of rings of main roll milling wheel base again exerts pressure, the distortion of ring base has two stages, it at first is common reaming process (this process can form more shallow further groove), when external diameter expands to after the little roll milling wheel in left side (being the signal wheel on the common Ring Rolling Machine) contacts, continue to exert pressure, this moment, ring outer Wednesday of place contacted with three roll milling wheels respectively, form the multi-point radial spreading, this moment, the core roller did not stress substantially, the ring endoporus substantially no longer enlarges (in the actual production process because of the existence of tangent direction friction power, the ring internal diameter has expansion and disengaging core roller slightly), when the thicker radial rigidity of ring wall thickness is big, ring can keep the garden degree, three roll milling wheels are when restriction ring internal diameter enlarges, metal to the ring periphery is rotated backward extrusion, make its ring periphery metal generation axial flow, until being full of die cavity, till peripheral groove is shaped and external diameter meets the requirements.And then control reversal valve and make three roll milling wheels all return and leave the operating position and take off workpiece.This class ring is how little because of the groove depth hole, if do not make three roll milling wheels leave the operating position, the workpiece that is enclosed within on the core roller is blocked and can't take out by the protuberance of the little roll milling wheel of both sides.In the multi-point radial spreading stage, three roll milling wheel radial forces close (because of angle is different different to some extent mutually), the fluid in the big chamber of both sides small oil tank 14 are because of by locking, and passive formation pressure in the chamber makes it the balance of exerting pressure with master cylinder.Should exert pressure according to the maximum of master cylinder and choose the cylinder diameter of small oil tank, make the oil pressure in the big chamber of small oil tank can not surpass the rated operating pressure (31.5Mp) of using hydraulic part always, when the maximum of master cylinder was exerted pressure to 500KN, the small oil tank cylinder diameter can be chosen for 140 millimeters.
(4) if the trough of belt dish of trough of belt ring endoporus very little (as duplicate gear etc.) or atresia, then can take the core roller away, the blank frame is placed on above two little roll milling wheels that enter the operating position, main roll milling wheel the change a job part and exerting pressure of band that descends also can be finished dark groove dish type (or annular) part forming of atresia (or aperture).
