Stamping monitoring device of nut forming machine

Abstract

The invention discloses a stamping monitoring device of a nut forming machine. The stamping monitoring device comprises a distance sensor, wherein a part of the distance sensor is arranged on a main sliding table, the other part of the distance sensor is arranged on a female die holder or a sliding rail, and the distance sensor is connected to an analysis control module. The main sliding table translates on the sliding rail so as to complete stamping steps. When equipment is operated without load, the main sliding table moves from a back starting point and returns after reaching a front stop point, the distance between the front stop point and the back starting point is a normal travel range within which the main sliding table can move, if an abnormity occurs, the position of the front stop point can exceed a normal variation range, and whether the stamping process is normally carried out is determined according to the standard. The measurement accuracy of the distance sensor is high, even small changes can be induced, and once the normal floating range is exceeded, the phenomenon is induced immediately, so that further large loss can be avoided.

Description

technical field [0001] The invention relates to the technical field of nut production and processing, and more particularly relates to a stamping monitoring device for a nut forming machine. Background technique [0002] When the nut is processed, it is necessary to punch the blank by a punching machine, process the inner hole of the nut, and then perform other operations. During stamping, the blank is fed into the mold on the female mold base by the front punching rod, and the shape is formed at the same time. A row of multiple front punching rods is set on a male mold base at the same time, and the stamping of multiple nuts is completed at one time. In the process of a large number of repeated operations, the front punch will inevitably be damaged, which will affect the normal stamping operation and cause uneven force. If it is not discovered in time, it will cause greater damage to other front punches. The traditional detection method is to judge according to the vibrati...

AI Technical Summary

Problems solved by technology

In the process of a large number of repeated operations, the front punch will inevitably be damaged, which will affect the normal stamping operation and cause uneven force. If it is not discovered in time, it will cause greater damage to other front punches.

The traditional detection method is to judge according to the vibration generated by the male mold base, but if only one front punch is damaged, the vibration amplitude caused is very small, which is not easy to be detected, and when the vibration amplitude is large, the damage of the front punch is often already high
