Detailed Description

The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the quick bending and forming bending machine for the Z-shaped plate comprises a fixed template a2 and a fixed template B3 for locking a plate to be bent, an upper moving template 40 hinged to the fixed template B3 through an upper moving hinge a41, a lower moving template 50 hinged to the fixed template B3 through a lower moving hinge a51, an upper thrust rod 6, a lower tension rod 7, an upper L-shaped connecting rod 8 and a lower connecting rod 9; and also comprises a coaxial gear 31 and a coaxial connecting rod 32 which are arranged on the frame.

Referring to fig. 1, the upper end of the upper traveling thrust rod 6 is hinged to the upper traveling block 40 by an upper hinge B42, and the lower end thereof is hinged to one end of the upper L-link 8 by an upper hinge C60.

Referring to fig. 1, the upper end of the down tension rod 7 is hinged to the lower movable platen 50 by a down hinge B52, and the lower end thereof is hinged to one end of the down link 9 by a down hinge C70.

Referring to fig. 1, the other end of the upward L-link 8 is hinged to the left end of the coaxial link 32 by an upward hinge D (80); the other end of the down link 9 is hinged with the right end of the coaxial link 32 through a down hinge D90.

Referring to fig. 1, the coaxial gear 31 and the coaxial link 32 rotate synchronously without relative rotation, and their rotation centers coincide, and an external power system is installed to drive the coaxial gear 31 to rotate, for example, an output shaft of a high-power motor may be connected to a rotating shaft of the coaxial gear 31, and the coaxial link 32 is driven to rotate synchronously by the rotation of the coaxial gear 31.

The upper moving die plate 40 and the lower moving die plate 50 are at the initial position of horizontal position, and their upper surfaces are at the same horizontal position as the upper surface of the fixed die plate B3.

The working principle is as follows: placing a plate to be bent between the fixed template A2 and the fixed template B3, and locking the plate through the fixed template A; the power system drives the coaxial gear 31 and the coaxial connecting rod 32 to rotate in the positive direction; the upward L connecting rod 8 pushes the upward thrust rod 6 to move, and further pushes the upward movable template 40 to move upward around an upward hinge A41; meanwhile, the descending connecting rod 9 drives the descending tension rod 7 to move downwards, and further pulls the descending movable template 50 to rotate downwards around the descending hinge A51; the upper moving die plate 40 and the lower moving die plate 50 respectively realize upward bending and downward bending forces on the plate, so that rapid bending is finished, and the bent plate is like the Z-shaped plate 1 in fig. 1.
