As seen in Figure 1, mould 1 is being fixed and is keeping workpiece 2.Adjustable shelf 3 is provided with a framework 30, and this framework comprises pre-flanging hyoplastron 31 and flanging hyoplastron 32.Adjustable shelf 3 is hinged on the balladeur train 4, and the latter can slide on a stationary base mount 5 by four guide rails 50 (Fig. 2).

The motion of flanging and pre-flanging is to realize by the rotation that is fixed on the motor M1 on the pedestal, and eccentric shaft 51 of this Motor Drive, this eccentric shaft comprise the axle A and the B of two off-centre, and is connected with a connecting rod.Axle A is the rotating shaft of motor M1, and it is fixed thus, and axle B is the lower shaft of connecting rod 6.This connecting rod 6 and balladeur train 4 collaborative works.Eccentric shaft 51 rotates a whole circle and at first makes balladeur train 4 declines and travelling carriage 3 is descended to realize flanging or pre-flanging, and balladeur train 4 is risen again.

Loading, discharging workpieces and the second motor M2 that moves through that locatees pre-flanging hyoplastron 31 or flanging hyoplastron 32 realize.

Motor M2 drives an eccentric shaft 40, this eccentric shaft be connected on the balladeur train 4 and be positioned at high position (flanging position) or lower position (pre-flanging position) on.This eccentric shaft comprises two axle C and D.Axle C is that the last rotating shaft and the axle D of connecting rod 6 is axles of motor M2.

Motor M2 also drives a crank 7, and the rotation of this crank moves rocker 9 by a connecting rod 8 up or down.

Rocker 9 is connected on the pedestal 5 by a guide rail 52, the motion of the vertical translation of this rail guidance rocker.

This rocker 9 is by connecting rod 33 and adjustable shelf 3 collaborative works.The distance of rocker 9 translational motions equals vertically moving of on flanging or pre-flanging position connecting rod 33, and when rocker 9 rose and breaks away from mould 1, this translational motion was ordered about adjustable shelf 3 towards its motion.

The whole motion of this device is described by accompanying drawing now.

Suppose consideration, motor M2 is on 0 ° home position, i.e. loading-unloading position (Figure 15 to 16), and adjustable shelf 3 breaks away from moulds 1 on this position.

On the position (Fig. 1 to 4) near pre-flanging, motor M2 rotates, until it rotates 90 °.This rotation is ordered about rocker 9 and is moved downward, and this motion allows resetting of adjustable shelf 3.

This rotation of motor M2 makes eccentric shaft 40 rotate 1/4th circles (90 °), and this makes it arrive a position, and promptly axle C is on the axle D of balladeur train 4 (Fig. 3).On this position, adjustable shelf 3 is on the upper/lower positions near pre-flanging.At this moment pre-flanging hyoplastron 31 be positioned at mould 1 and workpiece 2 above, and the flanging hyoplastron be positioned at they below.

At this moment motor M2 stops, and motor M1 is activated, to realize pre-flanging.

At this moment M1 finishes a whole circle (Fig. 5 to 7), and makes eccentric shaft 51 rotate a whole circle, and this eccentric shaft turns to B opposite location (upper/lower positions) of (referring to Fig. 6) below axle A from the position (position 0) of axle B on axle A, to return the home position again.The motion of this eccentric shaft makes balladeur train 4, adjustable shelf 3, and rocker 9 and pre-flanging hyoplastron 31 move down and realize thus pre-flanging.

At this moment motor M1 stops and motor M2 rotates with taking over.Motor M2 turns to 0 ° (Fig. 8 to 10) going up in the opposite direction from 180 ° with above-mentioned side.When this motor was on 105 °, connecting

rod

7 and 8 was positioned on the position identical with loading-unloading (Figure 15 to 18).At this moment rocker 9 is on the high position that breaks away from mould 1.

When 0 ° of motor M2 in-position, as what in Figure 10, see, crank 7 be in Fig. 3 near pre-antipodal position, flanging position, and connecting rod 8 is in and position near pre-flanging position symmetry thus.Connecting rod 33 is (Fig. 8) on the position perpendicular to adjustable shelf 3.

The rotation of motor M2 is also ordered about eccentric shaft 40 and is rotated, and makes following (Fig. 9) of the latter's axle C arrival axle D.Move up to result's balladeur train 4 translations of this motion and make flanging hyoplastron 32 be positioned at above the workpiece 2, so that flanging (Fig. 8).

In case arrive 0 ° of position, the flanging that motor M2 stops and motor M1 restarts to rotate a whole circle and realizes workpiece 2 like this as for pre-flanging.

In case the rotation of motor M1 stops again, motor M2 rotates again, is used to break away from mould 1, so that carry out discharging workpieces and load a workpiece for the treatment of flanging then, restarts this cyclic process.

This crimping unit can perform well in having the flanging of big workpiece of larger radius of curvature or the flanging of small workpiece.Because the very big distance of loading-unloading operation mould is left.

In addition, its function is highly stable, because moving component is being loaded on the guide rail on the stationary base mount and slides when pre-flanging and flanging operation.
