How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. suggest selecting appropriate punching and shearing process parameters?

1、 Board properties

The properties of the sheet metal have a significant impact on the selection of punching and shearing process parameters. The factors that need to be considered include the material, hardness, thickness, and surface quality of the sheet metal. For example, for harder sheet materials, it is necessary to choose larger shear forces and harder mold materials; For thinner sheets, it is necessary to adjust the shear gap and mold structure to avoid tearing or deformation during the shearing process.

2、 Shear thickness

Shear thickness is an important factor in selecting punching and shearing process parameters. Different thicknesses of plates require different punching shear forces and shear clearances. Thicker plates require greater shear force and clearance, while thinner plates require appropriate reduction of clearance to maintain shear quality and accuracy. When selecting process parameters, it is necessary to make reasonable adjustments based on actual needs and plate thickness.

3、 Accuracy requirements

Accuracy requirements are important considerations in selecting punching and shearing process parameters. If there is a high requirement for the dimensional and shape accuracy of the shear part, it is necessary to accurately control the punching force and stroke, while adjusting the shear gap and mold structure reasonably. For high-precision shear parts, it is recommended to use CNC punching and shearing machines or digital control systems to achieve more precise control and higher production efficiency.

4、 Production efficiency

Production efficiency is an important indicator for evaluating whether the selection of punching and shearing process parameters is reasonable. When selecting process parameters, it is necessary to balance the relationship between production efficiency and product quality. By optimizing parameters such as punching and shearing stroke, speed, and loading and unloading methods, production efficiency can be improved. Meanwhile, arranging production plans reasonably and optimizing equipment layout can also help improve production efficiency.

5、 Security protection

Safety protection is one of the important considerations in selecting punching and shearing process parameters. When selecting process parameters, it is necessary to fully consider operational safety and equipment safety. For example, setting reasonable travel and speed limits for punching and shearing, equipped with safety protection devices such as protective covers, guardrails, etc., to ensure the personal safety of operators. At the same time, it is essential to establish strict operating procedures and training plans, and improve the safety awareness and skill level of operators.

In summary, selecting appropriate punching and shearing process parameters requires considering a comprehensive balance of multiple factors. According to the actual situation, it is necessary to evaluate and adjust various factors to achieve the best process effect and production efficiency. Meanwhile, continuous optimization and innovation are also important ways to improve the level of punching and shearing technology.
