Precision plate bending machine having a play removing device

A plate bending machine for performing precise bending operations comprising:

• a machine pedestal having two opposite side sections;
• a pair of guide members provided at each side section of said machine pedestal;
• a pair of guide posts vertically movably supported by said guide member;
• a lower bending tool supported by said machine pedestal;
• an upper table having two side sections each supported by said guide post;
• an upper bending tool supported by said upper table and adapted to vertically move with said upper table to operate in cooperation with said lower bending tool;
• an eccentric shaft supported in a freely rotatable manner on said machine pedestal and having an eccentric section with which said guide post at its lower section is engaged, wherein there is play between said guide post and said eccentric section;
• and
• play removing means mounted on said machine pedestal, for removing the play between said guide post and said eccentric section;
• wherein said play removing means further comprises a pair of resilient members, one of each of said resilient members being mounted on one of each of the guide members in a manner such that each of the resilient members surrounds the respective guide member in a horizontal plane.
