Combined punching and shearing machines are crucial in modern metalworking. These versatile machines integrate punching, shearing, and bending functions, making them perfect for various industries such as metallurgy, bridge construction, communications, power generation, and military engineering. Known for their ease of use, low energy consumption, and minimal maintenance, they are becoming increasingly essential in industrial applications.

Mechanical vs. Hydraulic Punching and Shearing Machines

There are two primary types of combined punching and shearing machines: mechanical and hydraulic. Mechanical models feature a welded structure of cast steel and steel plates, providing robust strength and rigidity. These machines typically operate at 25-40 strokes per minute and are capable of punching 16-40 mm and shearing plates ranging from 8-20 mm thick.

Hydraulic models, on the other hand, use a hydraulic transmission system, reducing noise and vibration for smoother, more efficient operation. These machines typically operate at pressures between 630 and 1250 kN, with the ability to handle up to 31.5 MPa. The hydraulic system ensures steady power output, and with the oil temperature kept below 45°C, these machines offer stable long-term performance.

Key Parameters and Features

For instance, the Q35-16 mechanical model can generate a punching force of 630 kN, shear plates up to 16 mm thick, and punch holes with a maximum diameter of 28 mm, powered by a 5.5 kW motor. The QA34-25 model offers a greater punching capacity of 1100 kN, handles plates up to 25 mm thick, and punches holes up to 35 mm in diameter, powered by an 11 kW motor.

For hydraulic models like the Q35Y-16, a 7.5 kW motor and a system pressure of 25 MPa allow it to punch 16 mm thick plates and shear round steel, square steel, and angle steel. The Q35Y-25 model offers an even higher punching and shearing capacity, handling thicker plates and larger steel sizes.

Control Systems and Features

The QA35Y-30 hydraulic punching and shearing machine boasts an advanced PLC control system, featuring a 10.4-inch touchscreen for precise monitoring and adjustments. The machine includes self-diagnosis capabilities that alert operators when key parameters exceed safe thresholds, ensuring efficient and secure operation. Additionally, it comes with a quick die-change system, allowing for mold changes in under five minutes, reducing downtime during mass production. The automatic feeder, with a feed speed of 2000 mm/min and a positioning accuracy of ±0.1 mm, enhances production speed and precision.
