Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending machines, in particular to a pneumatic pipe bending machine. Background Art

[0002] Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, and the like. Pipe bending machines mainly use hydraulic pressure to perform winding bends on the pipe body with one or two bending radii in a cold state. They are widely used in bending various workpieces and wires in the automotive, air-conditioning and other industries. In the prior art, traditional pipe bending machines have problems such as low working efficiency, poor working stability, and easy damage to components during use. Traditional pipe bending machines cannot ensure that the workpiece does not deviate when bending the workpiece, and have poor compatibility for bending workpieces of different sizes. The top bending mechanism cannot remain stable when bending the workpiece, and the workpiece will deviate during top bending, resulting in unqualified workpieces, waste of workpieces, and increased labor costs.
