Description

Technical Field

[0001] The invention relates to a round bending machine, in particular to a horizontal round bending machine. Background Art

[0002] Traditionally, when bending profiles, cylindrical rollers are often used for bending. Traditionally, two rotatable rollers are set horizontally, and the profile to be bent is placed on the two rollers. Then, heavy objects are used to manually bend the profile on the two rollers to achieve the rounding process. However, if bending is done manually, the work intensity is high, the work efficiency is low, and the precision of the bent products is low.

[0003] Depending on the processing requirements of different workpieces, such as the weight of the workpiece, the shape required to be formed, etc., a vertical round bending machine or a horizontal round bending machine will be selected.

[0004] However, the traditional horizontal round bending machine includes three working rollers, two of which are used to form a supporting surface, and then the remaining working roller is used to apply pressure to the supporting surface to bend the profile. However, when the working roller applies pressure to the supporting surface, the working roller will vibrate during the movement, and the three working rollers themselves will rotate. However, the two working rollers that form the supporting surface do not limit the profile, so it is easy to cause the profiles on both sides to bend due to vibration, offset and other factors during bending, resulting in processing errors.
