What is a Sheet Metal Bending Machine?

The Sheet Metal Bending Machine is an electro-hydraulic synchronous double-cylinder top-moving CNC bending machine. The bending principle is basically the same as the angle forming principle of the ordinary bending machine. The forming of the bending angle (free bending method) is controlled by the depth of the upper die pressing the sheet in the lower die mouth (bending depth), or the workpiece is pressed Form the same workpiece as the angle (shape) of the mold (press bottom bending method).
So what is a Sheet Metal Bending Machine? The numerical control system controls the electro-hydraulic proportional directional valve, and forms a fully closed-loop digital control method of the bending depth through the feedback of the grating ruler. The numerical control system controls the ball screw driven by the AC digital servo system, and a semi-closed-loop digital control method for the positioning position of the back gauge is formed by a disc-type photoelectric encoder. Therefore, it can be briefly summarized as: a bending machine controlled by a numerical control system for automatic compensation of the backgauge positioning system, the bending depth of the slider, and the deformation of the worktable.
The conventional bending sequence of Sheet Metal Bending Machine:
Short side first, long side first: Generally speaking, when there are bending on all four sides, folding the short side first and then the long side is beneficial to the processing of the workpiece and the assembly of the bending mold;
Peripheral first and then middle: Under normal circumstances, it usually starts from the periphery of the workpiece and folds toward the center of the workpiece;
Partial first, then whole: If there are some structures different from other bending inside or outside of the workpiece, it is generally to bend these structures first and then bend other parts;
Consider the interference situation and arrange the bending sequence reasonably: the bending sequence is not static, and the processing sequence should be adjusted appropriately according to the bending shape or obstacles on the workpiece.
The operation of the Sheet Metal Bending Machine should comply with the operating instructions, safety operating procedures, and operating instructions of the bending machine, and all kinds of protection work should be done to ensure personal safety and safe bending operations of the equipment. Always pay attention to personal safety. When the equipment is turned on , Do not reach from the knife edge of the bending machine to adjust the rear gear; you should go directly to the back of the equipment to adjust; when processing parts, the human body should be outside the range of movement of the parts to avoid scraping the human body; the human body should stand firm during operation, The balance of the body cannot be affected by the movement of the workpiece; the removed tool cannot be placed on the bending machine, nor can it lean against the bending, so as to avoid the tool falling and hurting the human body.
