What is a mechanical power press?

In the vast field of manufacturing, mechanical power press, as an important metal processing equipment, play an indispensable role in multiple industries such as automobiles manufacturing, home appliance production, and electronic component processing with their efficient and precise punching capabilities. So, what exactly is a mechanical power press? How does it work? Let's unveil the mysterious veil of mechanical power press together.

1. Working principle

The design principle of a mechanical power press is to convert circular motion into linear motion. It is driven by the main electric motor, which drives the flywheel, and through the clutch, drives the gears, crankshaft (or eccentric gear), connecting rod, etc. to achieve linear motion of the slider. The motion from the main motor to the connecting rod is circular motion, while the circular motion between the connecting rod and the slider is converted into linear motion of the slider through a ball or pin (cylindrical) mechanism. The punch applies pressure to the material to cause plastic deformation, thereby obtaining the required shape and accuracy.

2. Type and Characteristics

1. Type:
-Mechanical power press can be divided into various types based on their structure, working principle, and driving force, such as steel plate fixed table punching machines, open tilting punching machines, deep throat punching machines, etc.
-Divided by tonnage, common mechanical power press have tonnages of 20 tons, 40 tons, 63 tons, 80 tons, 100 tons, 125 tons, 160 tons, 200 tons, 250 tons, etc., to meet the production needs of different scales.
2. Characteristics:
-Has a significant impact force, suitable for separation processes such as punching and cutting.
-Its body design is mostly open C-shaped, compact in structure, fast in operation, and high in efficiency.

-Mechanical power press usually use cast or steel plate welded bodies, with fixed working stroke and good stability.

3. Application Fields

Mechanical power press are widely used in stamping and forming processes in industries such as electronics, communications, computers, household appliances, furniture, transportation vehicles (such as automobiless, motorcycles, bicycles), and hardware components. It can cut the required shape through molds to meet the processing requirements of metal parts such as punching and deformation.

4. Selection and maintenance suggestions

1. Selection:
-When selecting and purchasing a mechanical punch, it is necessary to comprehensively consider the production demand, technical progressiveness, economy, reliability and maintainability, safety and operability, environmental protection and energy conservation.
-Select the appropriate tonnage and model based on factors such as the thickness, hardness, and production scale of the processed materials.
2. Maintenance:
-Regularly inspect and maintain the transmission components, electrical system, clutch, and brake of the punch press to ensure its normal operation.
-Lubricate key friction parts according to lubrication specifications to reduce friction coefficient and extend component life.
-Regularly calibrate the accuracy of the punch press to ensure that its machining accuracy meets the requirements.
In summary, as a key equipment in the manufacturing industry, mechanical power press provide strong support for the development of modern industry with their efficient and precise punching capabilities and wide application fields. With the continuous advancement of technology and the transformation and upgrading of manufacturing industry, the performance of mechanical power press will be more superior, and their application fields will also be more extensive. In the future, mechanical power press will continue to play an important role in the manufacturing industry, promoting the intelligent, efficient, and green development of industrial production.
