Abstract

The invention discloses a cam ejection device of a mechanical press. The cross section of the ejection device consists of a plurality of concentric arcs with different diameters. The arcs comprise a first circular arc, a second circular arc, a third circular arc, a fourth circular arc and a fifth circular arc, wherein the diameter of the first circular arc is R1; the diameter of the second circular arc is R2; the diameter of the third circular arc is R3; the diameter of the fourth circular arc is R4; the diameter of the fifth circular arc is R5; one end of the first circular arc is connected with that of the second circular arc through the first arc and the second arc; the sizes of R1, R2, R4, R3 and R5 are increased in sequence. Compared with a cam in the prior art, the cam ejection device of the mechanical press has the advantages that the ejection effect is better, and the accuracy is higher; the original one-time ascending and descending processes of the cam are divided into multi-step ascending and descending processes, and the ejection accuracy is effectively guaranteed.

Description

technical field [0001] The invention relates to a cam ejection device of a mechanical press. Background technique [0002] see figure 1 , figure 2 and image 3 As shown, the cross-section of the cam of the mechanical press in the prior art is composed of two arcs with different diameters and the same center and two arcs. The two ends of the two arcs are respectively connected by two arcs. The distance from one end to the other end and the center of the circle gradually increases or decreases, wherein the two arcs are respectively used as the ascending end and the descending end. Then when using the cam in the prior art as the ejecting device, there is only one rising process and one falling process, which will cause a large error due to mechanical stress. [0003] Therefore, need a kind of new mechanical press cam ejection device to solve the above-mentioned problem. Contents of the invention [0004] The purpose of the present invention is to provide a mechanical pr...
