Problems solved by technology

[0002] The stamping machine is used to process the blanks. After the processing is completed, the punching depth of the blanks needs to be detected. The existing detection method is to process a batch of blanks with an ordinary punching machine, and then manually process the batch of blanks. Carry out random inspection, and judge whether the batch of materials is qualified according to the defective ratio in the random inspection. If the defective ratio is high, it is judged that all the batch of materials are unqualified. Missed inspection, the missed inspection rate is high. On the other hand, if all the blanks are scrapped according to the test results, some qualified blanks will inevitably be scrapped, which will cause a lot of waste and increase production costs. Therefore, the existing manual sampling inspection method There are problems of low efficiency, high missed detection rate, and large waste

Abstract

The invention provides an on-line monitoring device and a monitoring method for a punching machine. Through the arrangement of a first laser displacement sensor on an impression male die, and a secondlaser displacement sensor and a strain sensor on an impression platform, real-time monitoring on a tablet processing process is performed, and monitoring on processing depth of each tablet is performed; defective tablets can be discovered in time, the detection efficiency is high, and the omission ratio is low.

technical field [0001] The invention relates to the technical field of stamping machine processing, in particular to an online monitoring device and a monitoring method for a stamping machine. Background technique [0002] The stamping machine is used to process the blanks. After the processing is completed, the punching depth of the blanks needs to be detected. The existing detection method is to process a batch of blanks with an ordinary punching machine, and then manually process the batch of blanks. Carry out random inspection, and judge whether the batch of materials is qualified according to the defective ratio in the random inspection. If the defective ratio is high, it is judged that all the batch of materials are unqualified. Missed inspection, the missed inspection rate is high. On the other hand, if all the blanks are scrapped according to the test results, some qualified blanks will inevitably be scrapped, which will cause a lot of waste and increase production c...
