Energy-saving precise press with multiple connecting rods

Abstract

The invention discloses an energy-saving precise press with multiple connecting rods, which is different from an eccentric-shaft type press and an eccentric-wheel type press. With the improvement on the awareness of environment protection and energy conservation and the fast development of precision industries, such as precision electronics, automobile parts and the like, requirements on an energy-saving precision press are increased daily. The invention aims to solve technical problems of saving energy sources, particularly electric energy; increasing a nominal travel; prolonging the residence time of a sliding block at a bottom dead center; and applying the press in a lignite fine-press molding process. The technical scheme provided by the invention is as follows: the press realizes low-input high-output by utilizing a double-level structure according to the lever principle; the energy source is saved by more than 80%; the usage amounts of materials, such as bearing steel materials, nonferrous metals and the like, are further reduced, and the domestic energy-saving and exhaust-reducing call is responded; the nominal travel can reach more than 40mm through the utilization of the double-lever structure, a running curve of the sliding block close to the bottom dead center tends to gentle, the residence time of the sliding block at the bottom dead center can reach as long as 1 / 12 of period and the difficulty of the press as a lignite fine-press molding device is solved.

Description

1. Technical field [0001] The invention is a multi-link energy-saving precision press machine, which is widely used in cold-temperature forging, stamping and other processes, and is also a press machine specializing in lignite precision pressing. 2. Background technology [0002] With the enhancement of people's awareness of environmental protection and the deep understanding of the enterprise development purpose of reducing costs and improving efficiency, the traditional eccentric shaft and eccentric wheel presses can no longer meet people's needs. With the rapid development of precision electronics, auto parts and other industries, the demand for precision presses is also increasing. 3. Contents of the invention [0003] In order to meet the national call for energy saving and emission reduction, reduce the use of bearing steel and non-ferrous metals, especially tin bronze and other materials, and solve the problem of fine pressing of lignite. The invention provides an ...
