Curved wood bending machine

摘要

A curved wood bending machine for bending solid, veneered or laminated wooden members has a support frame with a generally planar top member on which a plurality of guide rails are connected in predetermined circumferential relationship and radial planes from a common counterpoint on the top member so that clamping assemblies slidably mounted on the guide rails can be moved by suitable associated actuating means on the guide rails to predetermined positions relative each other. The clamping assemblies have a fixed vertical shoe and a coacting movable shoe which is activated by a suitable fluid pressure device such as a pneumatically operated cylinder and plunger arrangement so that a desired curvature can be established to fit and bend an elongated wooden member therein. Suitable locking members are provided to prevent accidental movement of the clamping assemblies after they are set for the predetermined shape for bending the elongated wooden member and a safety shield is provided to prevent operation and or release of the fluid pressure device on the clamping assemblies. Additionally, the curved wood bending machine, as above described wherein at least one or more of the clamping assemblies include, a two part base means for the operatively associated fixed and movable shoes which can be locked relative to each other for offsetting the fixed and movable shoes of each of such clamping assembly from the longitudinal line of the associated guide rail on which the clamping assembly is mounted. Additionally, the curved wood bending machine as above described including, a pair of coacting platens or expansion adapters to be connected to the fixed and movable shoes for increasing the area of and more uniformly distributing the curved wood bending machine.
