AI Technical Summary

Technical Problem

In stamping processing, it is difficult for the prior art to flexibly adjust the speed of the stamping line while maintaining molding accuracy, resulting in possible interference between the stamping device and the feeding device, and large-scale modification of the control program is required.

Method used

By generating a stamping device with a slider mounted with an upper die, a pad plate mounted with a lower die, and a servo motor, the motion of the slider in the up-down direction is controlled by using the motion generation device and method, so that the predetermined portions from the upper dead center to the end position of the molding area in the first cycle are the same, and the speed of the slider is kept consistent in different second cycles, thereby generating a second motion different from the first cycle.

Benefits of technology

It realizes the flexibly adjusting the stamping line speed while maintaining molding accuracy, avoiding interference between the stamping device and the feeding device, and simplifying the modification process of the control program.

Abstract

The present invention provides a motion generating device, a punching device, and a motion generating method. The motion generating device (3) is a motion generating device for generating the motion of a slider (11) of a punching device (5) having a slider (11) mounted with an upper mold (7a), a pad (12) carrying a lower mold (7b), and a servo motor (15) for reciprocating the slider (11) in the up-down direction. The motion generating device has a motion generating unit (32). The motion generating unit (32) makes the standard motion (Mi) of the slider (11) in the cycle (TStd) at least including the first area (Mim (1) from the top dead center to the end position of the forming area, and makes the speed of the slider (11) at the top dead center the same as the speed of the standard motion (Mi), thereby generating a derived motion (Mim) of the slider (11) in a cycle (Tm) different from the cycle (TStd).
