Abstract
A folding test machine to measure the durability against folding can be operated by minor adjustment even if a radius of curvature of the folding or an arc length of the folding is changed. A fixed wall and a moveable wall are opposingly provided in an approximately box-shaped frame and a holding part to hold a workpiece is provided on the top of each of the fixed wall and the moveable wall in a rotatable manner in a vertical plane of the rotation. And the workpiece and a plate spring are held on the respective opposing end portions so as to be bridged between the fixed wall and the moveable wall in a curved manner such that the moveable wall is moved closer to and farther from the fixed wall repeatedly such that the work is folded repeatedly.
Claims14
A folding test machine comprising:
- a fixed wall and a moveable wall arranged in an opposing manner inside the frame shaped in an approximately boxed-shape;
- a first holding part provided on a top of the fixed wall;
- a second holding part provided on a top of the moveable wall;
- a workpiece, a first end of which is held by the first holding part and a second end of which is held by the second holding part, wherein the workpiece in a plate shape is bridged between the first holding part and the second holding part;
- and
- a first plate spring provided beside a first side of the workpiece, the first plate spring being bridged between and held by the first holding part and the second holding part;
- wherein the workpiece and the first plate spring are bridged between the fixed wall and the moveable wall such that the workpiece is bent in a curved manner repeatedly in a same way as the first plate spring is bent during reciprocating movement of the moveable wall from the fixed wall.
A folding test machine to repeatedly fold a workpiece shaped in a plate comprising:
- a frame shaped in an approximately boxed-shape;
- a first workpiece holding part fixed to the frame;
- the workpiece, a first end side of which is held by the first workpiece holding part;
- a second workpiece holding part arranged in an opposing manner to the first workpiece holding part and disposed in a moveable way to the frame, the second workpiece holding part holding a second end side of the workpiece in a length direction thereof;
- a plate spring provided beside a first side of the workpiece, held in the length direction between the first workpiece holding part and the second workpiece holding part, and held by the first workpiece holding part and the second workpiece holding part;
- and
- an actuator connecting portion to be driven to move the second workpiece holding part closer to and farther from the first workpiece holding part;
- wherein the first workpiece holding part and the second workpiece holding part are configured to be rotatable in a plane that includes a direction of the movement;
- and
- wherein the workpiece is bent in a curve manner repeatedly in a same way as the platespring is bent during reciprocating movement of the first workpiece holding part relative to the second workpiece holding part.
A folding test machine comprising:
- a frame shaped in an approximately boxed-shape;
- a first wall and a second wall arranged in an opposing manner inside the frame;
- a first holding part provided in a rotational manner in a vertical plane on a top of the first wall;
- a sample of a plate shape, one end of which is held by the first holding part;
- a second holding part provided in a rotational manner in a vertical plane on a top of the second wall, the second holding part holding another end of the sample in a length direction thereof;
- a plate spring provided beside one side of the sample wherein the first holding part holds one end of the plate spring and the second holding part holds the other end of the plate spring such that the plate spring in a plate shape is bridged between the first holding part and the second holding part;
- and the sample and the plate spring are bridged between the first wall and the second wall in a curved manner such that the sample is bent in a curved manner repeatedly in a same way as the plate spring is bent during reciprocating movement of the first wall from the second wall.
