The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a bending machine.

Referring to fig. 1 and 2, the bending machine comprises a vertical frame 1, wherein an i-shaped placing base 2 is arranged on the frame 1, a rectangular bending base 3 is detachably arranged on the placing base 2 in a sliding mode, and a fixing part 4 for fixing the bending base 3 is arranged on the bending base 3. In this embodiment, the fixing member 4 may be a screw rod, and the screw rod penetrates through the bending base 3 and is in threaded connection with the bending base 3, and abuts against the placing base 2 to fix the position of the bending base 3. When the bending base 3 needs to be replaced to adapt to bending operations at different angles, the bending base 3 can be detached and replaced.

The frame 1 goes up and down to be provided with the slip post 5 that is the cuboid, and the slip post 5 is located the base 3 of bending and keeps away from the one side of placing base 2, and is provided with driving piece 6 that is used for driving 5 lifts of slip post in the frame 1. One end of the sliding column 5 close to the bending base 3 is provided with a plurality of clamping mechanisms 7, and one end of each clamping mechanism 7 close to the bending base 3 is detachably provided with a bending cutter 8 in a cuboid shape. In this embodiment, the driving members 6 may be air cylinders, and the gripping mechanisms 7 are preferably five. When the bending machine bends the plate, the driving piece 6 drives the sliding column 5 to descend, so that the bending cutter 8 is pressed on the plate, and the plate to be bent is bent.

All rotate along the horizontal direction on fixture 7 and set up supporting rod 9, supporting rod 9 is used for controlling fixture 7 and carries out the centre gripping operation to bending tool 8, and supporting rod 9 is the cylinder type. The one end that fixture 7 was kept away from to supporting rod 9 all rotates and is provided with dwang 10 that is the cylinder type, and the one end that supporting rod 9 was kept away from to dwang 10 is provided with action bars 11, and action bars 11 have connected a plurality of dwangs 10. When the bending tool 8 needs to be disassembled, the operating rod 11 is pulled, and then the rotating rod 10 moves, so that the clamping rod 9 on the clamping mechanism 7 is driven to rotate towards the direction far away from the clamping mechanism 7, and the clamping mechanism 7 releases clamping of the bending tool 8; when the bending tool 8 is fixedly installed, the operating rod 11 is pushed, so that the clamping rod 9 on the clamping mechanism 7 rotates towards the direction close to the clamping mechanism 7, and the clamping mechanism 7 clamps the bending tool 8.

Referring to fig. 2 and 3, the clamping mechanism 7 includes a support plate 71 and a front pressing plate 72 which are T-shaped, a connecting member 12 for connecting the support plate 71 and the front pressing plate 72 is disposed on the front pressing plate 72, a clamping rod 9 is rotatably disposed on the support plate 71, the clamping rod 9 penetrates through the front pressing plate 72, a clamping protrusion 13 for pressing the front pressing plate 72 is disposed on a side wall of the clamping rod 9 close to the support plate 71, and the clamping protrusion 13 is hemispherical. A rectangular parallelepiped holding groove 14 is formed between the support plate 71 and the front platen 72, and the bending tool 8 is slidably disposed in the holding groove 14. When the clamping mechanism 7 performs clamping operation on the bending tool 8 in the clamping groove 14, the clamping rod 9 is rotated, so that the clamping lug 13 on the clamping rod 9 presses the front pressing plate 72, and the front pressing plate 72 is pressed on the supporting plate 71.

The one end that the fixture 7 was kept away from to supporting rod 9 is seted up the spacing groove 15 of semicircle columnar shape, and just spacing groove 15 is close to preceding clamp plate 72, is provided with the stopper 16 with 15 looks adaptations joint in spacing groove on the preceding clamp plate 72. When the clamping rod 9 is rotated to fix the front pressing plate 72, the limiting block 16 is clamped with the limiting groove 15 in a matched mode, so that the position of the clamping rod 9 on the front pressing plate 72 is more stable, and the stability of the bending cutter 8 in the clamping groove 14 is further improved.

A compression elastic member 17 is provided between the support plate 71 and the front pressing plate 72, and when the front pressing plate 72 is released from the holding lever 9 by rotation, the compression elastic member 17 pushes the front pressing plate 72 away from the support plate 71 by its own elastic force, thereby allowing the bending tool 8 to be more easily taken out of the holding groove 14.

The groove 18 that slides has been seted up on the lateral wall that bending tool 8 is close to preceding clamp plate 72, be provided with on preceding clamp plate 72 with the gliding sliding block 19 of groove 18 looks adaptation that slides, when bending tool 8 slides in centre gripping groove 14, slide through sliding block 19 and the looks adaptation in groove 18 that slides, bending tool 8 slides more conveniently, and can play the fixed action to bending tool 8 in centre gripping groove 14, when the centre gripping, through sliding block 19 and the groove 18 looks adaptation that slides, the stability of bending tool 8 in centre gripping groove 14 has been improved.
