Detailed Explanation of Specific Support Plans "We offer comprehensive technical support from remote to on-site to ensure your downtime is minimized." " Remote technical support - Immediate response Telephone/video guidance: Guide operators to perform basic checks and operations, such as resetting alarms, checking fuses, sensor positions, etc.   Remote desktop connection: As mentioned earlier, this is the most core modern support method. Spare parts first: If a remote diagnosis detects that a certain module (such as a circuit board or encoder) is damaged, we can immediately arrange for the delivery of spare parts and at the same time guide the customer on how to replace them.   On-site technical support - ultimate guarantee Applicable scenarios: Major mechanical failures, core components requiring unpacking and repair, or complex precision calibrations. Dispatch process Remote diagnosis confirmation requires on-site support. Provide the engineer's resume and itinerary. After the engineers arrived, they repaired the faults, debugged the machines and retrained the local operators.   After the warranty period: A per-use charge or an annual service contract will be provided. Spare parts support - the cornerstone of maintenance Spare parts warehouse: Inform customers that you have sufficient inventory of commonly used spare parts (circuit boards, sensors, seals, etc.) to ensure prompt delivery. Shipping method: Depending on the urgency, we offer express logistics options such as DHL, UPS, and FedEx international express. Usually, it takes 3 to 5 days to reach major regions around the world. Used parts recycling: For some core components, a "trade-in" service can be provided to reduce customer costs.   Iii. How to Effectively Communicate to Customers Our goal is to offer you a service experience no different from that of local suppliers, or even faster.   We fully understand your concerns about after-sales service. For this reason, we have established a complete three-level technical support system   Level 1: Instant Remote Support: For any questions, please feel free to contact us via WhatsApp or email at any time. We promise to respond within 4 hours and resolve most software and setup issues through remote diagnosis. The second layer: Rapid spare parts supply: Our warehouse always keeps all commonly used spare parts in stock. Once it is confirmed that a replacement is needed, we will send it out by international express within 24 hours and provide a clear replacement guide. Layer 3: Professional On-site Service: For complex hardware issues that cannot be resolved remotely, we will dispatch experienced engineers to your factory to ensure that the machines are restored to their best condition. All charges will be transparently quoted in advance.   In addition, before each machine is dispatched, we will record a dedicated debugging and basic operation video to facilitate your team's learning. We believe that reliable after-sales service is the beginning of long-term cooperation.   if you have more ideas, please contact us!

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.
