The specific embodiment
In Fig. 1, with bearing (a 5) location roller (1), inside is the garden cylindrical space, and the one of which end is sealed by active catch head (2), the other end one section tubular blank (4) of then packing into earlier, after stretch into a roll shaft (3) with annular ditch groove; Roller (1), end socket (2), roll shaft (3) constitute mould, under external force drives, the inwall of blank (4) are carried out the combined type roller rolling extrusion process of hole enlargement and undergauge simultaneously, outside making it to become the face of cylinder are arranged, and interior is the qualified workpiece of cannelure.See the workpiece (4a) among Fig. 3.
In Fig. 4, there are gear ring and pinion (31) engagement in roller (1) outside, sees Fig. 4, and when the motor (not shown) was passed through around property driving member (34) drive pinion (31), roller (1) realized that angular speed is 1 at the uniform velocity rotation.
In Fig. 2, Fig. 3, Fig. 5, Fig. 6, the external diameter of retaining head (2) and the internal diameter of roller (1) are matched in clearance, when receiving the piston rod push-and-pull of oil cylinder (11), make axially reciprocating S
1, S
1Numerical value should be greater than the workpiece axial length; Roll in the process at roller, the material axial diffusion that it stops blank (4) plays the effect of mould; When roller is rolled over process finishing, workpiece (4a) is released outside the roller (1), play the effect of ejector beam.
Roll shaft (3) have centering rotation, radially back and forth, 3 kinds of reciprocal motor functions in the axle:
1), centering rotation: roll shaft (3) uses two bearings (5) and an end cap (17) (21) to be positioned in roll shaft side's cover (15) with being threaded in roll shaft body (12) end again; After roll shaft (3) radial translation touches blank (4), to do to feel relieved in the same way to rotatablely move by the frictional force drive roll shaft (3) that pressure P produces, angular speed is 2;
2), radially reciprocal: because roll shaft side cover (15) outside be square, with roll shaft casing (14) inwall be matched in clearance, under promoting about the plunger (23) of two plunger cylinders (13), realization roll shaft axis (O
2-O
2) and roller axis (O
1-O
1) from one heart to the reciprocating motion of off-centre, maximum eccentricity amount is (e);
3), axially back and forth: because roll shaft side's cover (15) is to be contained in the roll shaft casing (14), and the guide-track groove of roll shaft casing (14) bottom is installed in again on the lathe guided way (32), when receiving piston rod (19) push-and-pull of oil cylinder (11), realizes axially reciprocating S along guide rail
1S
1Numerical value should be greater than 2 times of workpiece axial length.
In Fig. 3, Fig. 4, Fig. 5, the combined type roller is rolled over extrusion process, if material plasticity is relatively poor, when need hot-working, roller (1), retaining head (2), roll shaft (3) all should be selected refractory steel for use, and prepare cooling device:
1), the cooling fluid of roller (1) constitutes circulation through two cannelures on the coolant jacket (10) with the outer cooling pumping plant (not shown) of fuselage, and 3 seals (7) prevent the cooling fluid leakage;
2), the cooling of retaining head (2) is to move back and forth S through elongated portion own
1In the process, directly touch 1 cooling fluid cannelure on the roller (1), reach the cooling purpose, so the length of elongated portion, should equal reciprocating stroke S
1
3), the cooling of roll shaft (3) is to have V shape through hole to be communicated with roll shaft body (12) cooling end cap (16) through itself, constitutes circulation with two flexible pipe (not shown)s and the outer cooling pumping plant (not shown) of fuselage at last; Owing between roll shaft body (12) and the roll shaft (3), rotation relationship is arranged when mounted, between roll shaft body (12) and the cooling end cap (16), when work, rotation relationship is arranged, so its two ends all have 1 circular trough and two O-ring seals to prevent heads.
Above-mentioned combined type roller is rolled over extrusion process, when material is soft metal, high-ductility, only cancels cooling system, and all the other all keep, principal section such as Fig. 6; Structure is simpler and compact, and the part code name is the same among the figure, so repeat no more.
Above-mentioned combined type Rolled machine adopts mechanical, electrically, liquid integrated, and behind the blank of packing into, roll shaft advances → and roller rotation → roll shaft translation → roll shaft return → roller stall → roll shaft retreats → keeps off a head return that advances → keep off; 8 programs of 1 workpiece of processing are carried out automatically successively.
Also should explain: lubricating system, cooling system, hydraulic system, electric-control system all belong to routine techniques, do not do the picture and text statement in this patent file.The present invention can material processed, is not limited to metal charge, and is obvious, for some material, relative dimensions adjusted change after, also can process, its architectural feature ought to belong to category of the present invention.
Above-described only is the preferred embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art; Under the prerequisite that does not break away from the principle of the invention, some distortion and the improvement made, such as: change roll shaft side's cover into eccentric bushing; Be positioned on the roll shaft casing with bearing again; When overlapping with the external force rotating eccentricity, roll shaft can be realized radially moving back and forth etc. equally, also should be regarded as belonging to protection scope of the present invention.
