The invention relates to the field of pipe-fitting machining, in particular to a pipe-fitting bending tool. The pipe-fitting bending tool comprises a supporting table, a bending plate, a repairing rod, an expansion mechanism, a transferring mechanism and a smooth transition mechanism; the bending plate and the supporting table are hinged, and one end of the repairing rod is connected with the supporting table; a groove is formed in the circumferential wall of the repairing rod, and the expansion mechanism is arranged in the groove; the smooth transition mechanism comprises a rotating rod, a round roller and two flat-rolling mechanisms; and the transferring mechanism comprises two transferring units. During adopting the technical scheme, bending operation is conducted on a pipe fitting, meanwhile, arc stretching and repairing are conducted on the inner wall of the bending position of the pipe fitting, and the inner wall of the bending position of the pipe fitting is prevented from deforming; and meanwhile, the inner wall of the bending position of the pipe fitting is subjected to expansion, the situation that the interior of the pipe fitting is blocked during bending of the pipe fitting is prevented, then the outer wall of the bending position of the pipe fitting is subjected to flat rolling, and smooth transition at the bending position of the pipe fitting is achieved.

In the whole bending process, the driving device is controlled through a program to drive the limiting device and the bending head to conduct automatic bending operation on the FPC to be bent, the stability is improved, the working efficiency is improved, and the manpower is saved.

The invention discloses a bending device for small-diameter and thin-walled metal pipes. The bending device comprises a frame. One end of the frame is provided with a clamping mechanism, and the other end is provided with a bending mechanism. The bending mechanism includes a first motor and a The first gear is sleeved on the first motor, the first gear is meshed with the second gear, the center of the second gear is provided with a first positioning shaft, the bottom of the first positioning shaft is fixed on the base plate, and the base plate is installed on the frame The upper end face of the first positioning shaft is fixed with a fixed wheel, the large gear is provided with a second positioning shaft that is not coaxial with the first positioning shaft, and the upper end face of the second positioning shaft is fixed with a bending wheel, a fixed wheel and a bending wheel There is a matching gap for accommodating thin-walled metal pipes with small diameters. The invention bends the pipe material to a preset angle through the bending mechanism, has little influence on the deformation of the pipe material during the bending process, the transition of the bending part is smooth, the degree of automation is high, and the processing precision is high, and it can be widely used in small diameters of different specifications. Bending of thin-walled metal pipes.

The application discloses an automatic bending machine, which includes a workbench, a mounting frame, a bending tool and a first pallet. The upper end surface of the workbench is provided with a V-shaped groove along the left and right directions, and the mounting frame is arranged above the workbench. The bending tool can be moved up and down on the mounting frame, and the lower end of the bending tool is located directly above the V-shaped groove; when the bending tool moves down into the V-shaped groove, the steel wire skeleton above the V-shaped groove can be forced to bend. Fold to form a V-shaped structure; the first pallet is arranged on the front side of the workbench, and the end of the first pallet far away from the workbench can rotate up and down around the end of the first pallet close to the workbench; when the first pallet rotates When reaching the horizontal position, the upper end surface of the first supporting plate is flush with the upper end surface of the workbench. It can bend the steel wire skeleton of the horizontal mesh structure twice to form a "匚"-shaped grid bridge frame, which is easy to operate, high in work efficiency, and small in labor, and can avoid the need to bend the longitudinal ribs in advance and affect the welding operation. efficiency.

The invention discloses a space pipe fitting flexible bending and torsion forming device which is used for forming space pipe fittings of any geometric shape. A movable die control mechanism controls the relative position of a movable die and a fixed die to control the bending radius, the torsion angle of a torsion mechanism is controlled to change the bending plane, feeding mechanisms are controlled to achieve continuous feeding, and thus the space pipe fittings are formed. A three-jaw chuck on the torsion mechanism is utilized to clamp the pipe fittings, and torsion movement of the pipe fittings is achieved. The torsion mechanism is fixed to the first feeding mechanism to achieve feeding movement of the pipe fittings. The movable die control mechanism is installed on the second feeding mechanism and drives a movable die assembly to be deviated relative to a fixed die assembly when the second feeding mechanism works to achieve bending operation. The movable die control mechanism drives the movable die to rotate relative to the fixed die, and adjustment is flexible. The feeding mechanisms are driven by motors, and the torsion mechanism and a bending mechanism are driven to achieve bending and torsion forming of the space pipe fittings in multiple directions.
