Machine used for punching ceramic dielectric chip of high-pressure ceramic capacitor and capable of preventing die damage

Abstract

The invention discloses a machine used for punching a ceramic dielectric chip of a high-pressure ceramic capacitor and capable of preventing die damage. The punching machine comprises an upper punch, a lower punch and a spacing lug boss. A die cavity is formed in the lower punch, and is filled with ceramic powders. After the height of the upper punch is reduced, the upper punch is matched with the lower punch, and the ceramic powders in the die cavity are punched to form the ceramic dielectric chip. A height sensor and a pressure sensor are arranged at the bottom of the upper punch. The height sensor can be used for detecting the ceramic powder filling height in the die cavity. The pressure sensor can be used for detecting the punching force between the upper punch and the ceramic powders or the lower punch. A feeding platform is located right above a frame. The other end of a feeding pipe is connected with a feeding vehicle located on the feeding platform. A second weighing sensor and a warning device are arranged on the feeding vehicle. After the structure is adopted, the punching force of the die can be monitored in time, and starved feeding and excessive punching of the die can be prevented, so that the die is prevented from being damaged, and the service life of the die is prolonged.

Description

technical field [0001] The application relates to the production field of ceramic capacitors, in particular to a high-voltage ceramic capacitor ceramic dielectric chip stamping machine capable of preventing mold damage. Background technique [0002] Traditional discrete components—ceramic capacitors are mainly in the form of discs. This structure is simple to form, mature in technology, easy to operate, and convenient for batch and large-scale production. But for high-voltage ceramic capacitors, the main consideration is that the withstand voltage strength and nominal capacitance are as high as possible. And the two are contradictory. Under the same conditions: the thinner the dielectric, the larger the capacitance and the lower the compressive strength, and vice versa. Traditional disc-type ceramic capacitors are relatively bulky, which is not conducive to the assembly of power devices. [0003] In addition, during the molding of ceramic capacitors, due to the lack of ti...

Problems solved by technology

However, the reliability of manual inspection is poor, and the occurrence of mold air pressure cannot be avoided.

Furthermore, due to improper molding setting parameters or too fast stamping speed, etc., the stamping force of the stamping mold may be too large, resulting in mold cracking or damage
