[0002] A punch press is a stamping press. Compared with traditional machining, the stamping process saves materials and energy, is highly efficient, has low technical requirements for operators, and can produce products that cannot be achieved by machining through various mold applications. Therefore, its use is becoming more and more extensive.

[0003] However, the existing punching machine has some defects in use. For example, the driving structure is placed on the right side of the top of the punching machine. This arrangement will cause the center of gravity of the punching machine to be biased to the right, which will cause the gravity on one side to be too large and easily lead to instability. In addition, the two existing crankshafts are not connected, and two sets of transmission structures are required to drive the two crankshafts to rotate. This is not only costly, but also difficult to ensure the concentricity and coaxial rotation of the two crankshafts, and thus cannot meet the needs of today's market. Utility Model Content
