The bending machine is the most expensive to install. Analytical sketch The operator must be fully familiar with its components. If the part has already been manufactured, it may not be necessary to modify the design, but ultimately the operator must understand that: Material type and density. Flange dimensions and tolerances. Necessary Angle and Angle tolerances. Angle inside the arc. Blank size. In the absence of any of these data, supervisors will need to make educated assumptions. The part is now at risk of being inaccurate. An important initial step is to obtain detailed drawings.   Tool selection The sketch is used to select the tool. There are several options for you to choose from: air bending, bottom bending, coinage or custom use. For example, if the layout requires a bottom tool and the internal arc length is equal to the metal density. For that particular type of machine, you should use a tool with at least the same precision as the tool manufacturer recommends. No matter how accurately the bending machine is installed, worn equipment will not produce the right product.   Calculated tonnage It should be easy for the operator to estimate the tonnage required. Regarding air bending, there seem to be tonnage charts available. A reasonable calculation for bottom bending is nearly three times the air bending tonnage. Stamping requires about eight times the bending tonnage of air. The supplier will provide tonnage estimates for custom application tools. Do not attempt to bend until you have determined the tonnage required and compared it to the tonnage provided.   Select a bending machine If you have only one press in your workshop, you can skip this step. If you have more than one press, make sure that the press you choose is best for the task at hand. The center of the press has a tonnage per inch limit. Multiply the length of the side panels by 0.6 to find the tonnage per inch of the press, then start dividing your estimate by the tonnage of the machine. For items 12 inches wide, the maximum tonnage of the machine center should not be higher than 25 tons. 25 tons over 12 inches will produce compression overload. This is a bad decision because it could permanently damage the ram. When using tonnage control (manual and CNC), be sure to use only the amount required for the torsion parts and do not exceed the tonnage threshold in the middle. Also, keep in mind that overload of the bender is only allowed when the bottom is compacted, cast, or air bent with dedicated tools. Select tool location If the required tonnage exceeds the concentrated weight limit at the center of the system, you may be able to complete the task off-center. However, you should first verify that the bender supplier allows eccentric loading to proceed. Eccentric work is acceptable as long as you follow the manufacturer's guidelines.

First, the basic concept and classification of bending machine Step 1 Define A bending machine is a device that produces plastic deformation in a mold by applying pressure to a sheet metal to form a predetermined Angle or shape.   2. Main types Mechanical bending machine: pressure is provided by mechanical transmission (such as gears, crankshaft), simple structure but low precision, suitable for small machining. - Hydraulic bending machine: driven by hydraulic system, high pressure, high stability, suitable for medium and thick plate processing. Numerical control bending machine (CNC) : through the CNC system to control the bending Angle, pressure and rear stop material positioning, high precision, high efficiency, suitable for mass production of complex workpieces. - Servo electro-hydraulic bending machine: Combining hydraulic and servo motor technology, energy saving and fast response speed. Second, the core structure and function of the bending machine 1. Fuselage: The frame that supports the overall structure must have high rigidity to withstand bending forces. 2. Slide block: a pressure component that moves up and down to connect the upper die and apply pressure. 3. Workbench: a platform for fixing the lower die, usually equipped with an adjustable V-shaped slot. 4. Hydraulic system (hydraulic/electro-hydraulic model) : composed of oil pump, cylinder, valve group, etc., to control pressure and stroke. 5. Back Gauge: the key component of CNC bending machine, which is used for plate positioning and directly affects bending accuracy. 6. Numerical control system (CNC model) : input parameters (Angle, pressure, stroke) to control the bending process. Third, basic knowledge of bending process 1. Bending principle - Pressure is applied to the sheet through the die to cause plastic deformation of the material. - Key parameters: bending Angle, bending radius, bending force (related to material thickness and strength).   2. Material characteristics - Elastic modulus: the ability of the material to resist deformation (such as stainless steel, which needs over-bending compensation). - Minimum bending radius: Avoid material cracking, depending on material thickness and type. - Springback: The Angle bounce of the material after unloading needs to be compensated by bending or mold design.   3. Bending force calculation - Formula: 'P = (1.42 × σb × L × t²)/V' -σb: Material tensile strength (MPa) -L: Bending length (mm) -t: Material thickness (mm) -V: lower die opening width (mm)   Four, mold selection and use 1. Mold type - Upper die (Punch) : Common shapes include sharp knife die, curved knife die, gooseneck die. - Lower Die (DIE) : The bending radius is determined by the width of the V-shaped groove, which should be selected according to the thickness of the material (usually the width of the V-port = the thickness of the material ×8). - Special mold: used for rolling, flattening, multi-step molding and other processes.   2. Mold materials - Tool steel (Cr12MoV), alloy steel, heat treatment to improve wear resistance.   3. Matching principle - Ratio of plate thickness to V-groove width (usually 1:8) to avoid material deformation or mold damage.   5. Operation process and safety specifications 1. Procedure - Equipment inspection (hydraulic oil, lubrication system) → Select mold → input parameters (Angle, pressure) → Position plate → bending test → adjustment compensation → mass production.   2. Safety precautions - Wear protective gloves/glasses to avoid cutting the board burrs. - Do not put hands in the mold area. - Check the tightness of the hydraulic system regularly to prevent oil leakage.   Six, common problems and solutions 1. The rebound is too large - Solution: Increase bending Angle compensation, use mold with correction function or CNC system. 2. Bending crack - Reason: poor material ductility or bending radius is too small → Replace soft material or increase R Angle. 3. Size deviation - Calibrate rear stop, check mold wear or NC system parameters.   Seven, equipment selection and market positioning suggestions 1. Target customer analysis - Sheet metal processing plants, chassis cabinet manufacturers, auto parts companies, etc. 2. Equipment selection - Small enterprises: hydraulic CNC bending machine is recommended (economical and practical). - High-end market: servo electro-hydraulic bending machines or high-precision models with laser detection. 3. Technology trends - Intelligent: Integrated AI Angle compensation, automatic mold change system. - Energy saving: servo motor drive to reduce energy consumption. Maintenance and maintenance 1. Routine maintenance - Clean mold and table debris. - Check hydraulic oil level and oil quality. 2. Regular maintenance - Replace hydraulic oil filter every 500 hours. - Lubricate moving parts such as guide rails and lead screws.
