1. Flexible operation mode: All the functions of the feeder are concentrated on the PLC and a portable knob. The operator can fix all the movement functions of the device in one place.So don’t worry about operating or wasting time because there are too many function keys.
2. High efficiency and safety: It reduces unnecessary time and improves work efficiency that mechanical action instead of manual operation. And it has a large number of auxiliary functions of feeding and supporting materials, so that the operator can keep away from the material to the maximum extent.
3. Convenient control mode: Users can freely switch between punch master or device master according to their needs, which maximizes the adaptability of the device and save costs for users.
4. Reasonable footprint: While Lihao NCHF series are powerful, the form factor are also the most reasonable in the industry, which can maximize the cost of the site.
5. Strong control system compatibility: The NCHF series uses a full set of Japanese Mitsubishi control systems, which are compatible with various standards at home and abroad. Users do not need to worry about data conversion and other issues, and can directly operate.
6. Reasonable design: The NCHF series is the first product in the industry to introduce industrial design. While ensuring the basic performance of the equipment, it maximizes the visibility of the equipment and improves the comfort of operation.
The frame part of the material frame is welded by Q235B that has a certain elongation, good strength and toughness, and is easy to punch and weld. So it is widely used in the manufacture of general mechanical parts. The Q235B material is laser-cut to ensure the flatness of the whole plate. After straight cutting, the hole is machined by CNC to ensure the accuracy of the hole position.After the hole is processed, it is formed by CO2 protection welding to ensure that the size of the rack is fixed. Finally, the internal structure of the steel is changed by annealing heat treatment to improve the performance of the steel. The heat treatment process can not only strengthen the metal material to fully exploit the material performance potential, reduce the structural weight, but also improve the quality of the mechanical products and greatly extend the service life of the machine parts. At the same time, it can eliminate the defects caused by the welding process, eliminate the segregation, reduce the internal stress and make the structure and properties of steel more uniform..
The spindle bearing bore is formed by a horizontal boring machine. The coaxiality is guaranteed to be below 0.015mm. The main shaft of the material frame is made of 40Mn tube forging. After spheroidizing annealing and quenching and tempering treatment, the flexibility of the main shaft is greatly enhanced, which is superior to the common carbon steel pipe commonly used in the industry. The shearing capacity maximizes the load carrying capacity of the spindle, so that the starting and stopping of the coil is smoother and the load of the motor is reduced.
·Left and right vertical board
The left and right vertical plates of the straightening head are made of cast steel ZG25 that has high strength, good plasticity and toughness, good welding performance, no deformation and high stability. The left and right vertical plates of each set of equipment will be opened with a mold, and then cast by ZG25, and then, by annealing, the material is exposed to high temperature for a long time, and then slowly cooled. The main purpose is to improve or eliminate various structural defects and residual stresses caused by steel during casting, forging, rolling and welding, to prevent deformation and cracking of the workpiece, to soften the workpiece for cutting, to refine grains and improve the structure to improve the mechanical properties of the workpiece, through the CNC pair processing, to ensure the accuracy of the right and left vertical plate holes and stability.
·Correct roller part
The correction roller is the core part of the Uncoiler ,Straightener,Feeder,3 in 1. The processing technology of Lihao Machinery is forged into round steel by GCr15. After pre-heat treatment (spheroidizing annealing),then it is stabilized by car, milling, intermediate frequency treatment and coarse grinding and deep cooling , then refining, and finally plating,which maximizes accuracy, concentricity, finish and hardness, extending the life of the correcting roller.
The gear machining process used by Lihao Machinery includes the following process: gear grinding processing - tooth surface processing - heat treatment- tooth surface finish grinding. The hair cultivating parts are mainly used for forging, and the normalizing treatment is carried out to improve the cutting.The gears are designed according to the drawings, followed by roughing, and then semi-finishing, car, rolling, and gear shaping, so that the gears are basically formed;then heat treatment is performed to improve the mechanical properties. According to the design requirements of the drawings, the final finishing, finishing the benchmark, finishing the tooth type. After the above treatment, our gear grade can reach 6 grades, high wear resistance, high strength and long service life.
