Remove dates from file names

Hi,

I'm using a shell script. I have extracted current date files to a directory1 and the date should be removed on both sides of a CSV file.

FYI... I'm looking to remove the date from the file name and not inside the CSV file.

Directory1

2017-07-12_gmr_tag_log_20170711.csv
2017-07-12_gmr_call_log_20170711.csv
2017-07-12_gmr_outgoing_log_20170711.csv

Final output Directory2:

gmr_tag_log.csv
gmr_call_log.csv
gmr_outgoing_log.csv
