Eight-bar servo press with triangular pendulum

Abstract

The invention relates to an eight-bar servo press with a triangular pendulum. The press includes a frame, a first crank, a second crank, a first connecting rod, a second connecting rod, a triangular pendulum, and a hammer connection. Rod and hammer, the first crank and the second crank are respectively connected with the frame through the rotating pair; the first crank is connected with the servo motor, and the servo motor drives the first crank to rotate; the first connecting rod and the first crank are rotated The pair is connected, the second connecting rod is connected with the second crank through the rotating pair, the first connecting rod, the second connecting rod and the triangular pendulum are connected at the same point through the revolving joint; It is connected with the hammer connecting rod, and the end of the hammer connecting rod is connected with the hammer through a rotating pair, and the hammer is in the fixed guide rail. The present invention can obtain diversified pressure working curves of the punching hammer, which solves the problems of poor "flexibility" and low quality of stamping forming of the traditional mechanical press; the addition of the triangular pendulum can make the working pressure curve of the punching hammer more diversified; At the same time, the press has good force transmission characteristics.

Description

technical field [0001] The present invention relates to non-cutting metal forming processing equipment, in particular to a mechanical press. Background technique [0002] In the field of metal forming processing, especially in sheet metal stamping, forming, and sheet drawing processes, hydraulic presses and mechanical presses are the main processing equipment. Hydraulic presses can realize large-tonnage stamping operations, but the work efficiency is low. The traditional mechanical press cannot obtain the pressure working curve required by the user according to different processing techniques. The inherent defect of the lack of "flexibility" of this kind of press hinders the further improvement of the stamping process level, so it is difficult to meet the requirements of high-quality stamping operations. In recent years, there have been servo presses, such as the connecting rod presses of Amino Corporation in Japan, Komatsu HF series presses in Japan, and Qiqihar Second Mac...
