Equipment structure and system configuration
1. The equipment frame and fuselage adopt a cabin-type keel structure. The equipment is welded and formed by square steel tubes and arc steel plates. After the stress is eliminated, the overall processing is performed to ensure that the equipment has sufficient strength, rigidity and stability. Four adjustable Height of the foot cup.
2. The parts and components of each part of the equipment are subjected to necessary surface treatments, such as electroplating, blackening, quenching, carburizing, electrostatic spraying, etc. according to the actual working conditions and working environment to meet the strength and surface functions of the parts.
3. The round mold is an integral mold; the guide mold can be equipped with a follow-up mold, a boosting device and an anti-crease device; the surface hardness of the molds such as the clamp mold, the guide mold, and the round mold is not lower than HRC50; the replacement operation of various molds is simple Convenient, and at the same time meet the requirements of processing technology of pipe fittings.
4. Linear axis feeding axis adopts high-speed linear motion components.
5. The head is an integral box structure, the curved arm adopts precision toothed chain transmission, the transmission sprocket and the reducer output shaft have support bearings at both ends, and the chain adjustment method is a butt-type double spiral structure.
6. Rotary shaft: It is driven by a power-increasing precision planetary servo reducer, and the independent servo system completes the feeding, bending and rotating control requirements.
7. Clamping mechanism: parallel quadrilateral movement mode, diagonal clamping, to ensure sufficient clamping force and avoid pinching of copper tubes, all joints have polymer non-lubricated bearings, and the guide mold uses slider links The structure has two strokes of half-return and full-return. 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;

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, and its clamping force is double. 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 rapid. The cutting head feed amount can be adjusted to adapt to different wear changes of the cutting tool. 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.
12. Tube end clamp: the power of the tube end is driven by hydraulic pressure;
13. Displacement mechanism: driven by servo.
