[0002] Whether the supporting device of the CNC bending machine is synchronized or not will directly affect the bending accuracy of the workpiece. In the bending machine in the prior art, the movement direction of the supporting point that drives the workpiece to rotate around the bending center line is vertical. , and for a fixed point on the workpiece, in the process of bending, the trajectory of its movement is arc-shaped. In this way, the traditional bending machine cannot realize the complete synchronous support of the workpiece, especially for relatively long The workpiece will obviously affect the bending accuracy

The invention discloses a synchronous follow-up material-supporting device of a numerical control bending machine, which is used for supporting a work piece to be machined, synchronously moves with an upper module slide block, and is used for bending the work piece to be machined. The supporting place between the upper module slide block and the work piece to be machined is formed into a bent central line. The device comprises a stander, a material supporting mechanism, a guiding mechanism, a driving mechanism, a transmission mechanism and an adjusting mechanism, wherein the material supporting mechanism is used for supporting the work piece to be machined, the guiding mechanism is used for limiting the running direction of the material supporting mechanism, the driving mechanism is used for providing a driving power to a guiding device, the transmission mechanism is used for transmitting the driving power to the material supporting mechanism, and the adjusting mechanism is used for adjusting the motion arc track of the material supporting mechanism to be concentric with the bent central line of the work piece to be machined; and the material supporting mechanism comprises a supporting table face and a circular rail supporting arm which is fixed under the supporting table face. By supporting and bending the work piece to be machined with the circular rail supporting arm which takes the point on the bent central line as the center of the circle, the device has the advantages of realizing the non-relative friction motion and the synchronous follow-up material support betweenthe supporting table face and the work piece, and improving the bending precision.
Description
technical field [0001] The invention relates to a synchronous follow-up material supporting device of a numerical control bending machine. Background technique [0002] Whether the supporting device of the CNC bending machine is synchronized or not will directly affect the bending accuracy of the workpiece. For the bending machine in the prior art, the movement direction of the supporting point that drives the workpiece to rotate around the bending center line is vertical. , and for a fixed point on the workpiece, in the process of bending, its movement trajectory is arc-shaped. In this way, the traditional bending machine cannot realize the synchronous support of the workpiece in a complete sense, especially for relatively long The workpiece will obviously affect the bending accuracy. Contents of the invention [0003] The object of the present invention is to provide a synchronous follow-up supporting device for a CNC bending machine in which the supporting point moves ...
