The bottom plate seat 3a is fixedly arranged on the equipment rack 1d. The screw 3c is connected to the output shaft in the vertical direction of the vertical gearbox 3b. One end of the screw 3c away from the vertical gearbox 3b is connected to the roller base 3d through a bearing. Connecting plates 3f are arranged on both sides of the roller base 3d, and both ends of the transfer roller (3e) are connected to the connecting plates 3f through bearings, achieving the purpose of free rotation of the transfer roller 3e. The transfer roller 3e has a V-shaped structure, so that the pipe material will not fall after entering. There are multiple transfer devices 3, and the transverse output shafts of the vertical gearboxes 3b arranged on two adjacent transfer devices 3 are connected through a coupling and a rotating shaft, so that multiple transfer devices 3 are connected. The power of the transverse output shafts of the vertical gearboxes 3b arranged on the two transfer devices 3 on the outermost side of the equipment rack 1d is provided by a servo motor.

When the pipe material rolls into the transfer rollers 3e from the wedge block 2c, the guide wedge block 4 plays a guiding role and at the same time prevents the pipe material from getting stuck in the gap between the equipment rack 1d and the transfer rollers 3e.

[0037] Working principle: During daily production, the raw material round tubes are stacked on the tube rack of this equipment. During production, the blanking device 2 lifts a single round tube from the stacked tubes. At this time, when the lifting cylinder 2b lifts the wedge block 2c, the round tube above the wedge block 2c is also lifted simultaneously. At the same time, the round tube will roll and roll towards one end of the transfer device through the inclined plane structure of the wedge block 2c, achieving the purpose of sorting the round tube from the tube stack into the transfer device 3. Then, the worker manually transfers the round tube that has fallen into the transfer device 3 to the cold bending machine. Due to the rotatable design of the transfer roller 3e, a great deal of manpower is saved during the transfer process, and the V-shaped transfer roller 3e has a limiting effect on the round tube, ensuring that the round tube will not fall off the transfer roller 3e during transfer. Through this equipment, a single round tube can be automatically separated from the stacked materials and conveniently transferred manually. Compared with the prior art of manual handling or hoisting for loading, this equipment has the characteristics of high efficiency and high safety.
