Specific implementation
The present invention is a kind of three rolls plate bending machine of lower roll adjustable center distance easy to adjust.
As shown in Figure 1, 2, 3: a kind of three rolls plate bending machine of lower roll adjustable center distance, it comprises oil cylinder 1, tilting device 2, lower roll 3, top roll 4, backing roll 5, horizontally moving device 6, frame 7, lathe bed 8, bascule 9, main drive gear 10, supporting roller bearing seat 12, bottom roll bearing block 13, the frame 15 of touching the pillow, two lower rolls all have mounting platform in the upper end and upper end supporting roller bearing seat 12 of corresponding bearing block 13 respectively, and the fastening connecting plate 16 that is equipped with in platform upper end connects into an integral body; Connecting plate 16 and bottom roll bearing block 13 or and lower support roller seat 12 between be provided with adjustable plate; Two bottom roll bearing blocks 13 are connected with two cover horizontally moving devices 6 respectively, the force-bearing base 26 of horizontally moving device 6 is connected with lathe bed 8, bearing block 13 is with in supporting roller bearing seat 12 is installed in the chute that is connected with lathe bed 8, when horizontally moving device moves bottom roll bearing block, thereby the drive mounting platform moves the driving backing roll and moves, moving horizontally two rollers all has digital display meter, shows the position of lower roll.
Shown in Fig. 4,5, the roller seat of working roll originally is two shared two bearing blocks of lower roll, and bearing block is an one, and centre-to-centre spacing is fixed, and lower roll and bottom roll bearing block can only be integrally-regulated; Bearing block after the improvement is divided into two, and each lower roller base all can be installed a cover adjusting device, and is adjustable separately, thereby centre-to-centre spacing is variable.
Backing roll is below lower roll, and backing roll originally is owing to be an integral body, two-wayly when lower roll moves all can promote a beaming roller and roller seat moves, and keeps the lower position of backing roll at lower roll.Because the roller seat of lower roll separately, every lower roll is the roller seat of backing roll and backing roll independently, adapts to the adjustable of lower roll centre-to-centre spacing like this.
The present invention passes to lathe bed with the vertical component of lower roll, because the good rigidly of lathe bed, the amount of deflection of lower roll vertical direction is less, and horizontal component is less relatively, and the horizontal amount of deflection of lower roll is also less, thereby the quality that rolls is better.Adjustable center distance is big when rolling slab, can increase it and roll ability, and centre-to-centre spacing is regulated lessly when rolling thin plate, can improve its manufacturing quality.
Connection between bottom roll bearing block 13 and the supporting roller bearing seat 12 reaches the adjusting of position each other and realizes in the following manner:
(1) as shown in Figure 6, machined has keyway on the mounting platform of bottom roll bearing block 13 and supporting roller bearing seat 12, and the position of keyway guarantees by processing, the back is installed guarantees that backing roll just in time is bearing in the below of lower roll, if error has appearred in processing, can be by the position of special-shaped key correction backing roll;
(2) as shown in Figure 7, on the mounting platform of bottom roll bearing block 13 and supporting roller bearing seat 12 boss is arranged, between boss and the connecting plate 16 adjustable plate is arranged, revise the thickness of adjustable plate during assembling and reach the position of regulating backing roll, regulates qualified after, the usefulness fastening bolt is fastening, bottom roll bearing block 13 and supporting roller bearing seat 12 become an integral body, bolt hole on the connecting plate is processed as the oval hole, is convenient to the adjusting of backing roll position, and chute or pressing plate prevent the lower roller base skew or tilt;
(3) as shown in Figure 8, the upper end of bottom roll bearing block 13 and supporting roller bearing seat 12 is the Plane Installation platform, has adjustable plate, when assembling to revise the thickness of adjustable plate and reach the position of regulating backing roll between connecting plate 16 and bottom roll bearing block 13 and the supporting roller bearing seat 12.After being adjusted to suitable scope, fastening with fastening bolt, bottom roll bearing block 13 and supporting roller bearing seat 12 become an integral body.Bolt hole on the connecting plate is processed as the oval hole, is convenient to the adjusting of backing roll position;
(4) as shown in Figure 9, the mounting platform of bottom roll bearing block 13 and supporting roller bearing seat 12 is placed with Baltimore groove 20, connecting plate 16 is put in the upper end of roll bearing seat 13 and supporting roller bearing seat 12, after regulating the relative position between bottom roll bearing block 13 and the supporting roller bearing seat 12 Baltimore groove 20 is welded on corresponding bottom roll bearing block 13 and the supporting roller bearing seat 12, being fastenedly connected back bottom roll bearing block 13 and supporting roller bearing seat 12 becomes an integral body;
(5) as shown in figure 10, be processed with the spill circular groove on the mounting platform of bottom roll bearing block 13 and supporting roller bearing seat 12, the two ends of connecting plate and the hole that adapts with reference column 21 is all arranged with the backing roll junction, be loose fit, with bolt location-plate is installed on bottom roll bearing block 13 and the lower support roll bearing seat 12, connecting plate 16 can rotate, form a kind of hinged connection, lower roll bearing and supporting roller bearing all adopt self-aligning bearing, this method of attachment can also be adjusted to lower roll " eight " font, be convenient to the processing of cone workpiece, four bearing blocks are shown by four displacement transducers the position of four oil cylinders to be controlled by microcomputer.
Aforesaid several different connected mode, can choose different connecting plates, shown in Figure 11,12,13,14,15,16, the connecting plate plate can be processed with bolt hole, connect with bolted, bolt hole can be processed into the adjusting that the backing roll position is convenient in the oval hole; Also can be processed into the hole that adapts with reference column.
The course of work:
(1), pre-bending steel plate two ends: two lower rolls 3 move horizontally to the same side, Hooks coupling universal coupling 9 is followed swing, makes top roll 4 be in the asymmetric position of two lower rolls 3, and top roll 4 is depressed, main transmission 10 drives two lower rolls by Hooks coupling universal coupling 9 and rotates, and reaches the purpose of pre-bending order steel plate head;
(2), roll: lower roll 3 symmetric position that is in top roll 4 that resets begins to roll, and repeats top roll and depresses the course of work roll-forming that rotates with lower roll;
(3), discharging: when workpiece after finishing workpiece on the veneer reeling machine, when top roll rose to the last stop location of bascule 9, top roll 4 was in poised state, the oil cylinder retraction of tilting device 2, touch the pillow frame 15 rotations greater than 80 degree, and top roll is in outstanding back of the body state, and workpiece is taken out from the side of touching the pillow.
When rolling slab, mobile and horizontal mobile device, thereby mobile bottom roll bearing block move thereby the drive mounting platform moves the driving backing roll, transfer twice rod centre-to-centre spacing big.
