Problems solved by technology

[0006] In view of the split structure of the inclined block or wedge of the compensation device in the prior art, it is easy to cause cumulative errors, and the machining accuracy cannot be guaranteed; and it can only be adjusted in the horizontal direction, and the vertical adjustment cannot be realized, resulting in bending of the workpiece of the sheet metal The problem of poor consistency of the entire length of the angle and poor straightness of the workpiece, the purpose of the present invention is to provide a precision two-way mechanical deflection compensation device for the bending machine workbench. Accumulate errors to match the deflection compensation amount of the workpiece with the actual deflection deformation of the workpiece to ensure the consistency of the bending angle of the workpiece and the straightness of the workpiece

Description

Technical field [0001] The invention belongs to the technical field of bending machines, and more specifically relates to a precision bidirectional mechanical deflection compensation device for a worktable of a bending machine and a manufacturing method thereof. Background technique [0002] In the process of bending the plate, the bending machine often inevitably exists the force of its own structure to cause elastic deformation of the slider. Although the amount of deformation is extremely small, for high-precision bending workpieces, the workpiece is still It is easy to produce deflection and deformation, and the full-length consistency of the angle cannot be guaranteed. For traditional press brakes that use hydraulic pressure as the source of force, due to the uneven force of the cylinder, the workpiece will have a deflection in the length direction during the bending process, and the ultra-long bending die is often used for bending. Bending a short workpiece will cause the ...
