As shown in Figure 4, above-mentioned rolling extrusion head 4 comprises that addendum cone 41, addendum cone bearing 42, addendum cone seat 43, taper roll bearing 44, motor connect splined shaft 45 and spline housing 46.Wherein, addendum cone 41 is installed on the head end of addendum cone seat 43 by addendum cone bearing 42, and can rotate freely.Addendum cone bearing 42 comprises a cylinder roller bearing and a taper roll bearing.The shaft axis coplane of the shaft axis of addendum cone 41 and rolling extrusion head 4 but do not overlap.Roll along required enlarging inner wall of metal tube during addendum cone work, the two is contacted with addendum cone lateral surface and inner wall of metal tube contact wire 411, and after addendum cone 41 installations, its addendum cone lateral surface and inner wall of metal tube contact wire 411 are acute angle with the shaft axis of rolling extrusion head 4.
In order to reach the technique effect of wanting required for the present invention, the key of above addendum cone seat 43 end faces and rolling extrusion head 4 shaft axis angles and addendum cone 41 type selecting is, must guarantee after addendum cone 41 is installed, its addendum cone lateral surface and inner wall of metal tube contact wire 411 have an angle with the shaft axis of rolling extrusion head (4), and addendum cone 41 axis do not overlap with the shaft axis of rolling extrusion head 4, guarantee that with this enlarging mode is the rolling compression flare.
As shown in Figure 4, the outside in rolling extrusion head 4 stage casings is placed and be fixed in to a pair of taper roll bearing 44 subtends, and piston body 12 inwalls of taper roll bearing 44 outsides and hydraulic cylinder 1 join and be fixing, and the inboard outside with addendum cone seat 43 joins and be fixing.Spline housing 46 is fixed in the inner hole inwall of addendum cone seat 43 tail ends.Motor is set in the spline housing 46 connects splined shaft 45.Head end and spline housing 46 that motor connects splined shaft 45 are connected, and tail end extends to outside the addendum cone seat 43, and passes the axis hole of piston body 12 and motor adpting flange 15 central authorities, and the machine shaft with reducing motor 3 is connected then.
As shown in Figure 5, above-mentioned clamp mechanism 5 comprises base 51, mould 52, clamping plate 53 and clamping lever 54.Described base 51 is the U type; Described clamping plate 53 is arranged at base 51 upper openings, and two ends and base 51 are closely fixing; Described clamping lever 54 passes the perforate at clamping plate 53 middle parts, and is threaded with it; Described mould 52 by base 51 and clamping plate 53 around, and clamping lever 54 lower ends are with in mould 52 upper surfaces closely contact and be fixed in the U type opening of base 51.Inclined-planes are consistent with addendum cone lateral surface and inner wall of metal tube contact wire 411 inclination angles in the mould 52, and with required enlarging metal tube type matching, as the die cavity and the qualification of enlarging.Mould 52 is used with addendum cone 41, and can change according to the metal tube type of required enlarging.
As shown in Figure 2, the operation principle of this rolling and squeezing flaring machine for metal tube is as follows.
Reducing motor 3 and clamp mechanism 5 are individually fixed in the two ends of hydraulic cylinder 1.Rolling extrusion head 4 is positioned within the hydraulic cylinder 1.The machine shaft uniform rotation of reducing motor 3, the motor that drives rolling extrusion head 4 connects splined shaft 45 and rotates simultaneously, by spline housing 46, drives the axis uniform rotation of addendum cone seat 43 around rolling extrusion head 4.The addendum cone 41 that is installed on addendum cone seat 43 head end also rotates around the axis of rolling extrusion head 4 thereupon.This moment, addendum cone 41 phase double cone seats 43 were static, do not rotate along its axis.
At this moment,, will pass through pipeline near the liquid in the enclosed cavity of reducing motor 3 one ends between hydraulic cylinder 11 and the piston body 12, be transferred near in the enclosed cavity of clamp mechanism 5 one ends by the effect of manual pump 2.Because dividing plate 13 is fixed in the inwall of hydraulic cylinder 11, thereby this liquid shifts and can move slowly to clamp mechanism 5 directions by promotion piston body 12.The taper roll bearing 44 of piston body 12 inwalls and then promotion addendum cone seat 43 move slowly to clamp mechanism 5 directions, and slowly approaching to the metal tube mouth of pipe that is fixed on the clamp mechanism 5.Meanwhile, because the effect of taper roll bearing 44, piston body 12 does not rotate, and addendum cone seat 43 is still around the axis uniform rotation of rolling extrusion head 4.
Because the lateral surface of addendum cone 41 and the shaft axis of rolling extrusion head 4 are acute angle, thereby can the slowly inboard and finally contact with it near the metal tube mouth of pipe of required enlarging near the edge of clamp mechanism 5 at the lateral surface of addendum cone 41.Because addendum cone 41 still slowly moves to clamp mechanism 5 directions subsequently, and simultaneously around the axis uniform rotation of rolling extrusion head 4, thereby can roll along the metal tube mouth of pipe inside circumference of required enlarging in the outside of addendum cone 41, and it is consistent with the axis angle of addendum cone 41 outer ledges and rolling extrusion head 4 that it is squeezed to the inner wall of metal tube angle of inclination, finishes enlarging thus.In the middle of this process, addendum cone 41 relies on addendum cone bearings 42 to rotate with respect to addendum cone seat 43 along self axis.Because the qualification effect of mould 52 on the clamp mechanism 5 can be so that the enlarging degree of the metal tube mouth of pipe can not exceed needed scope and degree.
After finishing enlarging, regulate the changement of manual pump 2, the liquid in the hydraulic system is transferred near in the enclosed cavity of reducing motor 3 one ends by the enclosed cavity near clamp mechanism 5 one ends.According to same operation principle, piston body 12, taper roll bearing 44, addendum cone seat 43 and addendum cone 41 all oppositely slowly move, gradually away from the metal tube of finishing the enlarging operation.
Above-mentioned explanation and accompanying drawing have provided the specific embodiment of the present invention and details thereof.Those of ordinary skill in the art will recognize that the present invention can implement in many other concrete structures, and those of ordinary skill in the art does not need too much experiment can implement these related embodiment.As the purpose of this patent file, protection scope of the present invention thereby not only be subject to the concrete preferred implementation of above-mentioned explanation, but propose by claim.The method of equivalence and any all changes in the scope all are regarded as comprising within the spirit and scope of the present invention in the claim.
