8.The rotating shaftis driven by a power-increasing precision planetary servo reducer, and the independent servo system completes the feeding, bending and rotating control requirements.
9.The clamping mechanismis a parallelogram movement mode, and the mold is clamped diagonally to ensure sufficient clamping force and avoid pinching of the copper tube. All joints have German polymer non-lubricating bearings. Rod structure, with two strokes of semi-retracting and full-retracting. The material clamp adopts a three-lobed chuck structure to ensure sufficient clamping force, mechanical strength and service life; the core has a rapid positioning and anti-rotation device;
10. The feeding rack adopts internal pumping type (or automatic feeding rack) to reduce the tension of the feeder; the guide rubber hose must be wear-resistant and cannot be discounted; the copper pipe has no scratches or scratches;
11.Straightening unit:It adopts the whole substrate mounting method, which is convenient for specification change. The copper pipe is passed through a pair of round rollers to eliminate local deformation. The straight and horizontal planes of the copper pipe are provided with 5 straightening wheels, and the amount of straightening deformation can be adjusted according to the soft and hard states of the copper pipe. Each straightening wheel has a smooth surface and is equipped with two bearings, which effectively guarantees straightening accuracy and stability.
12.Fixed-length feeding mechanism:The ball screw is driven by an AC servo motor. The feed guide adopts a wear-resistant polished rod and linear bearings. It is flexible in movement and the feeding clamp adopts a booster cylinder.
13.Cutting mechanism:The outer rotating cutter and the supporting roller structure are used. In order to prevent the copper tube from sliding during pre-tensioning, which will cause the cutter to break, the copper tube fixing clamp is clamped by a two-stage booster cylinder. The clamping force is twice as large as that of the pulling die. The feeding mechanism adopts an independent cylinder feeding component to advance and return. The feeding is stable and the withdrawal is fast. The necking rate of each nozzle is the same. Equipped with intermittent blade fuel injection device, each cutter head is provided with volatile oil lubrication nozzles to extend the service life of the blade.
14.Displacement mechanism:The lead screw is driven by a servo motor, the precision movement guide is translated, and the up and down are driven by an air cylinder.
15.Unloading manipulator:after processing is completed, servo and precision movement screw. Pneumatic mechanical fingers hold, push and unload.
16.Hydraulic system:built-in oil tank, equipped with or air-cooled heat exchanger, this equipment mainly uses (pneumatic) or oil pressure, such as variable pressure pump when oil pressure, energy-saving, low-noise design of oil circuit.
17.Pneumatic components:The main pneumatic components of the equipment are used for various actuators and fuel injection. The pneumatic circuit has devices for voltage stabilization, purification, lubrication and pressure adjustment.
18.Electrical control: adopt a set of CNC centralized control or PLC man-machine interface control. With manual operation of each process, automatic operation of the whole machine.
19.Alarm indication:power supply, no material, cycle completion, cycle abnormality, emergency stop, overheat trip, cuttingabnormality, product discharge abnormality and other functions. The operation panel consists of man-machine interface, knob and emergency stop button, with clear identification and easy operation.
20.The installation of the electricalcomponents of the equipment conforms to the relevant national regulations and has a reliable grounding device. The terminals, contactors and small air switches in the electrical box are installed in the VDE standard V-groove. Each electrical component is clearly marked. The electric control cabinet uses all-plastic combing cabinets with wire trunking for clear wire numbers; the control panel is clean and the subtitles on the signs are clear and easy to see.
21.Safety protection:The installation of the electrical components of the equipment conforms to the relevant national regulations, and there is a reliable grounding device, a protective cover, and automatic operation stops when the protective cover is opened.
