The top of the first lower die plate and the second lower die plate is provided with a circular groove adjacent to the bending profile. A rolling cylinder matching the circular groove is arranged in the circular groove. The rolling cylinder can roll in the circular groove. An oil channel is arranged on the bottom plate. The bottom of the first lower die plate and the second lower die plate is provided with a plurality of oil delivery channels communicating with the circular groove. The input end of the oil delivery channel communicates with the oil channel.

[0005] Preferably, the circular groove is arranged through the two end faces of the first lower die plate and the second lower die plate.

[0006] Preferably, the oil channel includes an oil delivery groove arranged on the top surface of the bottom plate and an oil inlet hole arranged on the side surface of the bottom plate and communicating with the oil delivery groove.

[0007] The utility model discloses an anti -scratch thick material bending die structure, through the input end of oil circuit delivery lubricating oil, lubricating oil can be delivered to the circular groove through the oil circuit, oil channel, and lubricating oil can play the lubrication between the circular groove and the rolling cylinder, place hardware between the top of first lower mould plate and second lower mould plate, when the punch of upper punch is pressed to hardware, will lead to the deformation of hardware and drive the rolling cylinder to roll in the circular groove, prevent the bottom both ends of hardware and the top of first lower mould plate and second lower mould plate from adhering, avoid the surface wear of hardware, ensure product appearance complete, improve product pass rate.
