Inertia force balance method of high speed punching machine crank connecting rod sliding block mechanism

Abstract

The invention discloses a method for balancing the inertial force of a crank lingage slider mechanism of a high speed punching machine, which is characterized in that: the mechanism that the crank lingage slider mechanism produces inertial force is disclosed, a correct calculating formula of the balancing mass of an eccentric block of a large gear on a crankshaft when the inertial force is in total balance is derived by taking the total balance of the inertial force as the design thought and the crank lingage slider mechanism with fully symmetric double-point or four-point double cranks as the basis, thus realizing the purpose of reaching the balance of the inertial force at a vertical direction by adjusting the mass of the eccentric block according to different mass of moulds, and obtaining good dynamic balance effect from the practical application in 1000kN high speed punching machine industry.

Description

technical field [0001] The invention relates to a method for balancing the inertial force of forging equipment, in particular to a method for balancing the inertial force of a high-speed punch press crank connecting rod slider mechanism. Background technique [0002] In recent years, with the rapid development of electronics, communications, computers, home appliances and automobile industries, the demand for functional stamping parts that tend to be standardized and serialized in size and shape has grown rapidly. Such parts are very suitable for mass production on high-speed punching machines, so in order to reduce costs and improve labor productivity, high-speed punching machines are more and more widely used in industrial practice. However, due to the large gap between our country's theoretical research level and manufacturing level of high-speed punching machines and foreign countries, the number of strokes per minute of the sliders used in domestic high-speed punching m...

AI Technical Summary

Problems solved by technology

However, due to the large gap between our country's theoretical research level and manufacturing level of high-speed punching machines and foreign countries, the number of strokes per minute of the sliders used in domestic high-speed punching machines in industrial practice is not high, and the work is extremely unstable. Shock vibration and The noise is large, and it is almost impossible to be used in production practice, so the industry mainly relies on a large number of imported foreign high-speed punching machines

Due to the confidentiality of technology, there are almost no relevant literature reports on the design theory and methods of high-speed punching machines abroad, and the export of high-precision, first-class high-speed punching machines to China is also restricted.

There are very few people who carry out theoretical research in this area in China. The rational transmission mode of high-speed punch presses, the theory of motor and flywheel design, the method of inertial force balance have not been established, and the problems of reasonable vibration isolation methods and mold height adjustment methods have not been solved, which has seriously affected the industry. The development of my country's high-speed punch industry hinders my country's high-speed punch from catching up with foreign advanced levels
