Die quick-changing device for forming steel plate in mining equipment

The utility model relates to the technical field of steel plate processing, and provides a die quick-change device for forming a steel plate in mining equipment, which comprises a fixed plate, a vertical plate fixedly connected on the fixed plate, a quick butt-joint component arranged on the vertical plate, a steel pipe bending die arranged on the quick butt-joint component, and a through hole formed in the through hole. The penetrating holes are formed in the side surfaces of the vertical plates, butt joint sleeves are fixedly connected to the two opposite side surfaces of the vertical plates, a transverse plate is fixedly connected between the vertical plates, and inserting holes are formed in the surface of the transverse plate. By means of the technical scheme, the problems that in the prior art, when different arc-shaped steel plates are stamped, an upper die needs to be replaced, the distance between two round pipes needs to be correspondingly adjusted through a lower die, replacement is inconvenient, a
