Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic bending machines, in particular to a bending angle adjustment mechanism for a hydraulic bending machine. Background Art

[0002] A bending machine, also known as a press brake, is a machine that can bend plates.

[0003] At present, most bending machines are usually manually fed and bent during actual use. However, during the bending process, the plate needs to be pushed or lifted by hand to the bottom mold, which has high labor intensity for operators. In addition, the bent position cannot be accurately controlled, and the upper mold is easy to fall out of the guide groove when sliding along the guide groove.

[0004] For example, a hydraulic bending machine disclosed in Chinese patent CN210614715U, through the setting of the position baffle, the bending position of the plate is determined, and the baffle moving mechanism realizes the front and rear adjustment of the position baffle to control the bending position. Through the setting of the baffle moving mechanism, the fastening bolt is used for the position baffle to slide along the sliding groove, and the baffle fixing part is fixed to the position of the sliding groove to realize the front and rear position adjustment of the position baffle. Through the setting of the scale on the sliding groove, the bending position of the plate can be controlled more accurately.

[0005] However, the device cannot adjust the bending angle during use, which brings inconvenience to the bending of the plate.

[0006] For this reason, we urgently need to provide a bending angle adjustment mechanism for a hydraulic bending machine. Utility Model Content
