What is a punching press machine

A punch is a punching press. In national production, the stamping process saves materials and energy compared with traditional machining, has high efficiency, does not require high technical requirements for operators, and can make products that cannot be achieved by machining through various mold applications. Its uses are getting wider and wider.

Stamping production is mainly for sheets. Through the die, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts can be made, which are widely used in various fields. Such as the switches and sockets we use, cups, cupboards, dishes, computer cases, and even missile aircraft... There are many accessories that can be produced by punching through molds.

working principle of punching press machine

The design principle of the punch press is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to operate to achieve the linear motion of the slider, from the main motor to the The movement of the connecting rod is a circular motion.

Between the connecting rod and the slider, there needs to be a transition point for circular motion and linear motion. There are roughly two types of mechanisms in its design, one is a ball type and the other is a pin type (cylindrical type), through which the circular motion is moved. Converted to linear motion of the slider. The punch presses the material to plastically deform it to obtain the required shape and precision. Therefore, a set of molds (upper mold and lower mold) must be matched to place the material in between, and pressure is applied by the machine to deform it. , the reaction force caused by the force applied to the material during processing is absorbed by the machine body of the punch press

Uses and Features of punching press

Punch presses are widely used in stamping and forming of electronics, communications, computers, household appliances, furniture, transportation, (automobiles, motorcycles, bicycles) hardware parts and so on.

1. ⑴High rigidity and high precision frame, welded by steel plate, and heat treated to eliminate the internal stress of the fuselage, so that the equipment can work stably for a long time without deformation.

(2) The load of the structural parts is uniform and the rigidity is balanced.

2. Stable high precision:

The main components of the equipment, such as crankshaft, gears, transmission shafts, etc., have been hardened and heat-treated to have high wear resistance after grinding, and the long-term performance is stable, which ensures the requirements of high precision and stability.

3. Reliable and safe operation performance:

The reason why it is easy to operate and accurate in positioning is because the combination of clutch/brake has high sensitivity, which is different from the traditional brake, coupled with the double solenoid control valve and overload protection device commonly used in international high-end equipment, It ensures the precision and safety of the high-speed movement and stop of the punch slide.

4. Production automation, labor saving and high efficiency.

The punch press can be equipped with the corresponding automatic feeding device, with feeding error detection, pre-cutting and pre-breaking devices, which can fully realize automatic production with low cost and high efficiency.

5. Slider adjustment mechanism:

The sliding adjustment is divided into manual adjustment and electric adjustment, which is convenient, reliable, safe and fast, and the accuracy can reach 0.1mm.

6. Novel design and environmental protection.

Using advanced technology and design concepts from Japan and Taiwan, it has the advantages of low noise, low energy consumption and no pollution.
