High voltage circuit breaker air cylinder riveting die

Abstract

The invention discloses a high voltage circuit breaker air cylinder riveting die which is arranged on an air cylinder riveting machine frame. The die comprises a die body and a plurality of groups of punching units radially connected onto the periphery of the die body. A cavity used for containing workpieces is axially arranged in the middle of the die body, and punches of the punching units can be punched into the cavity in the radial direction. The punching units serve as a whole. When some parts are damaged, users can simply replace the corresponding parts. The die is convenient and reduces cost. The punches have functions of guiding and punching, the part number of the punching units is saved, the punching units are simple in structure, and the cost is reduced.

Description

Technical field [0001] The invention relates to the field of high-voltage circuit breaker manufacturing, in particular to a riveting die for a pressure cylinder of a high-voltage circuit breaker. Background technique [0002] The pressure cylinder is a core component of high-voltage circuit breakers used in the power industry today. With the comprehensive development of domestic and international high-voltage power grids today, the level of production efficiency and production cost determines the level of competitiveness of high-voltage circuit breakers in the international market. The pressure cylinder riveting die for high voltage circuit breaker (also called pressure cylinder riveting machine) is an indispensable part of the pressure cylinder assembly process. Its performance and accuracy play a key role in the assembly quality of the pressure cylinder. In order to improve the production efficiency of the pressure cylinder, Germany, France, India, China and other countries ha...

AI Technical Summary

Problems solved by technology

[0004] Take the air cylinder riveting machine developed in Germany as an example. It has high riveting precision, good product performance, advanced technology, and easy operation. A single mold can realize multiple riveting of the air cylinder with good controllability. It is used by German riveting machines. The internal use of pressure sensors in the indexing turntable is one of the fundamental reasons for its high riveting accuracy, but the disadvantages that come with it are that the cost is too high and it is not adopted by most countries; in contrast, France is slightly inferior to Germany in terms of performance and technology, and the cost is about half of Germany; the price of the cylinder riveting machine produced in India is cheap, but the technology and precision are not high, and the performance is also incomparable with Germany and France.
