Abstract

The invention relates to a drawing ejector rod mis-assembling detection system and an automatic die changing method for a punching line. The drawing ejector rod mis-assembling detection system comprises a supporting plate, a driving device, a sensor and a control device, and the supporting plate is used for bearing a drawing ejector rod; the driving device is connected with the supporting plate and is used for driving the supporting plate to vertically eject the ejector rod; the sensor is connected with the driving device and is used for measuring the jacking force of the driving device; and the control device is connected with the driving device and the sensor, and the control device is used for controlling the driving device to work and judging whether the mis-assembled drawing ejector rod exists or not according to the relation between the jacking force measured by the sensor within the set time and a set threshold value. According to the drawing ejector rod mis-assembling detectionsystem and the automatic die changing method for the punching line, the problems of long whole-line die changing time and low equipment starting rate in related technologies can be solved.

Description

technical field [0001] The present application relates to the technical field of automobile manufacturing, and in particular to a detection system for wrong assembly of drawing ejector pins and an automated mold changing method for a stamping line. Background technique [0002] The stamping production line is a robotic automated production line, and each press is equipped with two workbenches. When the stamping line is in production, the press will only stamp the drawing die on one of the workbenches, while the other workbench is used to prepare for the automatic die change of the whole line, such as replacing the drawing ejector, drawing Mold lifting, etc. [0003] see figure 1 and figure 2 As shown, the workbench 6 is provided with a first hole 60 and a second hole 61 for installing the drawing mandrel 2. Before hoisting the drawing die 7 to the workbench 6, the operator needs to base on the "holding position" of each part. Rod Layout" Place the drawing ejector pin 2 ...
