What impact does the punching speed of the press have on the section of metal stamping parts?

Blanking is a stamping process that uses molds to separate the sheet metal of metal stamping parts. With the development of society, studies in practice have proved that the stamping speed has a great impact on the quality of the blanking section in high-speed precision progressive stamping; and according to The characteristics of the servo press are designed with different stamping speeds. The results show that for the H1F60CS press, when the speed is set at about 20%, the quality of the cross section is the best, and the experience of world production can improve the quality of the cross section when cutting at low speeds Consistent; the figure shows the height values u200bu200bof each section of the section at different punching speeds. When the speed is about 20%, the actual speed of the slider is about 9mm/s; by analyzing the height values u200bu200bof the sections under different punching speeds, when the punching speed is set at When the normal speed is about 20%, the bright band of the blanking parts reaches the maximum, while the burr is smaller, and the cross-sectional quality is the best. However, when the speed is reduced, the height of the bright band decreases and the burr height increases, indicating that the blanking speed cannot be blinded. Decrease, otherwise it may be unfavorable to improve the quality of the section. When the speed is increased, the bright band is slightly reduced, but the height of the burr is relatively increased; therefore, the reasonable blanking speed should be set at about 20% of the normal speed; the article recommends: why should Lubricate stamping materials and molds?
