Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe processing, and specifically relates to a stamping and flaring device for bending metal pipes. Background Technique

[0002] A stamping and flaring device is a device used for flaring metal pipes, mainly composed of a punch, a die, a press, a clamping device, a control system, etc., and is suitable for flaring processing of metal pipes with various different shapes and sizes.

[0003] Chinese Utility Model Patent Publication No.: CN 210334061 U, discloses: a stamping and flaring forming device. In this stamping and flaring forming device, the movable clamping arm is hinged to the main body bracket to form a lever structure. In this way, the lever principle can be utilized to apply force to the force-receiving end of the movable clamping arm, so that the movable clamping arm rotates around the hinged part, and thus the clamping end cooperates with the fixed clamping arm to clamp the pipe fitting. Since there are two power mechanisms, the two power mechanisms are respectively located on both sides of the force-receiving end, and at least one power mechanism is connected to the force-receiving end. Thus, one power mechanism applies a pulling force to the force-receiving end, and the other power mechanism applies a pushing force to the force-receiving end, which is equivalent to double the acting force. Therefore, a greater clamping force can be generated to meet various clamping needs, and further ensure the flaring quality of the pipe fitting. However, this stamping and flaring forming device cannot fix and stamp and flare a bent metal pipe, and has certain limitations. Summary of the Utility Model
