Description

Technical Field

[0001] The utility model relates to the technical field of metal bellows bending equipment, and specifically relates to a metal bellows bending and shaping device. Background Technique

[0002] A metal bellows is a pipe with a regular wavy shape on the outer surface, mainly made of metal materials such as carbon steel, stainless steel, steel-lined plastic, and aluminum. In the prior art, in some occasions, it is necessary to bend the metal bellows for use. However, during the bending process of the metal bellows, there is a lack of heat treatment for the bending part, resulting in relatively laborious bending of the metal bellows. Bending without heat treatment may cause problems such as deformation, breakage, or uneven bending angle of the steel pipe because the steel pipe is relatively hard in the cold state and is not easy to be bent at a large angle.

[0003] For example, a steel pipe bending device disclosed in the authorized patent document with the application number 202022397579.3 includes a base, a rotating seat, and a front rotating seat. The base and the rotating seat are arranged at intervals along a first direction. One end of the front rotating seat is pivotally connected to the rotating seat so that the power mechanism of the rotating seat can drive the front rotating seat to rotate in the horizontal plane; a baffle extends along the first direction on the outer wall of the fixed seat at the top of the rotating seat and extends to one end of the top of the base, and a left template extends along a second direction on the outer wall of the fixed seat. A right template is provided at the top of the other end of the front rotating seat, and a movable pressing plate is provided at the other end of the top of the base; the base is also provided with a mounting seat, and a fixed rod is provided on the mounting seat and the front end of the fixed rod is located between the baffle and the movable pressing plate; the first direction and the second direction are perpendicular to each other. This steel pipe bending device is applicable to the bending of all steel pipes and has excellent bending quality.

[0004] The above patent lacks heat treatment for the bending part, resulting in relatively laborious bending of the metal bellows. Therefore, we need to provide a metal bellows bending and shaping device. Content of the Utility Model

[0037] In this embodiment, the surface of the corrugated metal pipe to be bent is attached to the guiding disc 7 and the abutting disc 5. The heating screw rod 82 and the fan 84 are started. The external air is sucked into the frame 81, and the air inside the frame 81 is heated by the heating screw rod 82. The hot air will be blown to the part of the corrugated pipe surface that needs to be bent through the exhaust slot 83, so as to make it more labor-saving to bend the corrugated pipe.
