Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4 and Fig. 5, a kind of adjustable gradual four-roll plate bending machine of radius of curvature, are passed by upper roller
Motivation structure, two side roller cylinder transmission mechanisms and lower roller transmission mechanism composition, upper roller transmission mechanism and side roller cylinder transmission mechanism
It is made of purely mechanic transmission mechanism, lower roller is made of hydraulic gear.
Such as Fig. 1 and Fig. 2, a kind of adjustable gradual four-roll plate bending machine of radius of curvature, upper roller 1 is respectively by left support plate 12
With the fixed position of right support plate 13, pure rolling is realized by transmission mechanism passing movement；Front side roller 2 and rear side roller 3 are angled
The two sides for being mounted on the lower section of upper roller 1, realize that oblique line moves up and down by transmission mechanism passing movement；Before lower roller 4 is mounted on
The lower section of side roller cylinder 2 and rear side roller 3 and same perpendicular is kept with upper roller 1, is realized by transmission mechanism passing movement
Straight line moves up and down.
Such as Fig. 3, a kind of upper roller transmission mechanism of the adjustable gradual four-roll plate bending machine of radius of curvature, by main motor 7
Multi-stage speed reducer 9 is connected, is slowed down after increasing torque, then connect by shaft coupling 10 with upper roller 1, upper roller 1 and 4 clamping plate of lower roller
Material, upper roller 1 is rolled drives plate to roll between roller by frictional force, and the volume of cylinder needed for completing is combined with other movements
System.
Such as Fig. 4, a kind of two side roller cylinder transmission mechanisms of the adjustable gradual four-roll plate bending machine of radius of curvature, front side roller
2 and rear side roller 3 primarily serve the circular arc effect for rolling out certain curvature, two rollers can with self-movement, two side roller cylinders
Size is the same, positional symmetry and transmission mechanism having the same, therefore only introduces the transmission mechanism of the side roller cylinder of side, i.e. preliminary roller
The transmission mechanism of cylinder 2, transmission mechanism connect a single reduction gear 16 by secondary motor 14, are exported simultaneously after deceleration by both ends,
And following transmission mechanism is connected to identical shaft coupling 17 respectively；Because guaranteeing that the level at roller movement both ends is steady
Property, so the transmission mechanism at roller both ends is identical, therefore only introduce on one side, i.e. left side, is passed through by the deceleration of single reduction gear 16
