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

Stamping production is mainly for sheet metals. Through the mold, it can make blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion, etc., which are widely used in various fields. Such as the switches and sockets we use, cups, cupboards, plates, computer cases, and even missiles and airplanes ......There are a lot of parts that can be produced by punching through molds.

1. From the drive: mechanical and servo punch (servo).

At present, most of the pneumatic punches used on the market are mechanical punches driven by ordinary motors, with flywheels and clutches, and can not be freely programmed to set the running speed of the slider and the residence time of any position in a single stroke.

The servo punch is driven by a servo motor, without a flywheel and clutch, and can freely program the running speed of the slider and the residence time of any position, and the bottom dead center accuracy is also higher than that of the mechanical punch (can be achieved.

2. From the fuselage: open (C type) and closed (O type).

The open punch is generally below 300t, with a single axis (single point) punch press, the working table is larger, the overall structure is not as stable as the closed punch, and the opening phenomenon is easy to occur during long-term operation, which has a certain impact on the accuracy. For manufacturers with high requirements for product accuracy and stability, especially punches above 300t, closed-structure punches are generally selected.

In the closed punch, according to the manufacturer's requirements for the working table and the strength of the punch, it can be divided into one-piece punch and split punch (three-split type).

According to its use and characteristics, the punch has the following types, which can be applied to one or more stamping processes.

1.Universal punch press.

The universal punch press is the most common type of press. It is suitable for a variety of stamping processes, such as blanking, shallow drawing, bending and stamping. General purpose punch press according to nominal pressure.

The size is divided into large, medium, and small. The nominal pressure of the small punch is less than 1000kn; 1000 3000kN for medium punches; More than 3000kn is a large punch. According to the characteristics of the bed structure, the general punch is divided into two types: open punch and closed punch.

The pressure of the open punch press is smaller, generally between 25-4000kN. The nominal pressure of the closed punch is larger, generally above 1600 16000kn.

2.Drawing (drawing) punch.

This kind of punch is suitable for the drawing process, according to the position of its transmission system is divided into upper transmission and lower transmission punch: according to the number of its sliders, it is divided into single-acting, double-acting, three-action drawing punch.

3.Dedicated punch press.

The special punch is used to stamping a certain complex shape of the part, such as the die rotary head press belongs to this kind of special punch.

4.Fine punching press.

Fine blanking punch is a punch specially suitable for punching precision parts.

5.Fine press.

Fine press is a punch machine suitable for precision extrusion, leveling, embossing and other stamping operations.

6.High-speed punching press.

The high-speed punch has a higher number of strokes per minute (referred to as strokes per minute) of the slider, or its corresponding automatic feeding speed is higher, which is suitable for the production of automatic forming and stamping operations of large quantities of products.

1.According to the driving force of the slider, it can be divided into two types: mechanical type and hydraulic type, so the punch press is divided into two types according to the different driving force it uses

1) Mechanical

powerpress)

2) Hydraulic punch (hydraulic

press)

In general, sheet metal stamping is processed, and most of them use mechanical punching machines. Hydraulic punch according to the different liquids used, there are hydraulic punches and hydraulic punches, the current use of hydraulic punches accounted for the majority, hydraulic punches are mostly used in large machinery or special machinery.

2.Classification according to the way the slider moves:

According to the slider movement mode classification has single-acting, double-acting, three-action punches, but the most used at present is a single-action punch of a slider, and the double-action and three-action punches are mainly used in the extension processing of automobile bodies and large processing parts, and their number is very small.

Stamping can be made of blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion through molds, etc., which are widely used in various fields. Such as switches, sockets, cups, cupboards, plates, computer cases, etc.

The design principle of the punch is to convert the circular motion into linear motion, and the main motor outputs the force to drive the flywheel, and drives the gear, crankshaft (or eccentric gear), connecting rod and other operations through the clutch to achieve the linear movement of the slider, and the movement from the main motor to the connecting rod is circular motion.
