[0002] The press is a general-purpose press with a sophisticated structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. It applies strong pressure to the metal blank to cause plastic deformation and fracture of the metal to make it into parts.

[0003] After searching: Patent number CN211803187U is a press for bending steel plates, which relates to the field of aircraft manufacturing technology. The press includes: a bracket, a crossbeam, a pressure rod, a pad, a hydraulic station and a hydraulic cylinder; the crossbeam is installed on the top of the bracket, the crossbeam is suitable for moving in a horizontal plane relative to the bracket, the hydraulic cylinder is fixed to the crossbeam, the hydraulic cylinder is connected to the hydraulic station, the hydraulic station is used to drive the piston of the hydraulic cylinder to reciprocate, the piston of the hydraulic cylinder is connected to the pressure rod, the pressure rod is vertically arranged downward, and the end face of the bottom end of the pressure rod is a spherical surface. And a press for punching cables with patent number CN213530414U, including a base, and a limited card groove is provided on the rear inner wall of the base. The cable punching press adjusts the position of the support base plate by adjusting the extended length of the support hydraulic column, thereby adjusting the distance between the support base plate and the positioning support plate. Through the cooperation between the support adjustment rod, the positioning support plate, the side pressure block and the bending adjustment rod, the support adjustment rod is rotated, and the support adjustment rod drives the positioning support plate to move laterally, thereby adjusting the distance between the two positioning support plates.
