Cycle time optimization method for hybrid lines of servo and mechanical presses

Abstract

The invention discloses an optimization method of servo and mechanical press mixed line beat. The optimization method comprises the steps of S1: setting a starting range and a starting signal; S2: setting a signal detection range; S3: setting running and stopping signals of presses in the detection range; S4: setting a pause restarting range during the press running process; S5: setting a maximum quick stopping brake angle of the presses; S6: setting a maximum urgent stopping brake angle of the presses; and S7: integrating and naming the setting from S1 to S6 as a continuous running mode, and adding the mode into the selection menu. According to the optimization method, through changing the running manner of a servo press from single running manner to the continuous running manner, higher whole line beat is obtained at relatively low press impact frequency, the impact to a mold is smaller, the service life of the mold is prolonged, a better drawing effect is achieved, the failure rate of the device is effectively decreased, the energy consumption is reduced, and the maximum economic income is obtained through relatively low investment.

Description

technical field [0001] The invention relates to the technical field of automatic stamping lines, in particular to a beat optimization method for a hybrid line of servo and mechanical presses. Background technique [0002] In the original mechanical automation stamping line, the press mostly uses a single working mode to operate. In this way of working, each time the press completes a stroke, it needs to stop at the top dead center, and wait for the manipulator to take away the stamped parts and put in new parts before the press can start a new stroke again. In this way of working, in order to obtain a relatively high stamping beat of the whole line, the press needs to run at least 1.6 times the stamping beat of the whole line. If the stroke frequency of the press is too high, the impact on the mold will be very large, the stretching effect on the parts will be poor, the design performance of the press will have higher requirements, and the failure rate of the press will inc...

AI Technical Summary

Problems solved by technology

If the stroke frequency of the press is too high, the impact on the mold will be very large, the stretching effect on the parts will be poor, the design performance of the press will have higher requirements, and the failure rate of the press will increase

Based on the above limiting factors, it also restricts the beat increase of the stamping production line, and the production efficiency is relatively low
