Abrasive press device for press beam of belt grinder, has pressing rod and press element mechanically decoupled from cylinder piston, and flexible resetting element generating resetting force on rod and press element

摘要

The device (100) has a valve cylinder unit (20) for generating pressing force on a pressing rod (12) and a press element (11) by applying pressure on a pressure medium cylinder (21b). The pressure medium cylinder comprises a cylinder piston (21a), where the pressing rod and the press element are mechanically decoupled from the cylinder piston. A flexible resetting element i.e. reset spring (17), generates resetting force on the pressing rod and press element. The pressing rod is provided with an abrasive guide (13). An independent claim is also included for a belt grinder comprising a metal profile.
