Description

Technical Field

[0001] The invention belongs to the technical field of punching machines, and in particular relates to a full-automatic feeding punching machine. Background Art

[0002] A punch press is a mechanical equipment commonly used in metal processing. It is mainly used for stamping, die cutting, forming, die casting and other processes. It uses impact force to shape metal materials (usually plates) into the required shape and size in the mold. Punches are widely used in the manufacturing industry.

[0003] 1. Working principle of punch press: The punch press is processed by a fixed die and a movable punch. When working, the punch moves downward under the pressure of the punch press, exerting force to make the metal material pass through the die and finally form the desired shape.

[0004] 2. The main operation process of the punch press includes: Feeding: feeding the metal sheet to be processed into the working area of ​​the punch press; Punching: The punch moves downward, applying pressure to press the metal sheet into the die; Discharging: After processing, the formed parts are removed from the mold and the waste is discharged or recycled.

[0005] 3. Advantages of punch press Efficient production: large-scale production can be carried out quickly to improve production efficiency; High precision: capable of manufacturing parts with precise dimensions and consistent shapes; High material utilization rate: reduce material waste and reduce production costs.

[0006] 4. Main types of punch presses Mechanical punching machine: It uses a mechanical transmission system to provide impact force. Common punching machines include flywheel punching machine and crankshaft punching machine. These punching machines are suitable for high-productivity continuous stamping processing. Hydraulic punching machine: uses a hydraulic system to provide pressure, which is suitable for scenarios that require flexibility and adjustment of processing pressure. Hydraulic punching machine can perform more complex stamping processes and has strong adaptability to materials; Pneumatic punch press: The impact force is provided by the pneumatic system. Pneumatic punch presses are usually used for punching tasks that require lower force and are suitable for fast production. Electric punch press: Using an electric motor to provide the impact force, electric punch presses are suitable for high-precision and high-repeatability processing tasks.
