Under the global epidemic, several companies rejoice and some worry, many companies have fallen into negative growth, and many companies have gained momentum because of the epidemic. One of them is bicycle manufacturers.

European countries have gradually “unblocked”, and for safety reasons and policy subsidies, people are rushing to buy bicycles, Chinese bicycle exports have skyrocketed, Spain has skyrocketed by 22 times, and Italy and the UK have also increased by about 4 times. China's upstream and downstream bicycle factories, spin-off electric vehicle and electric scooter factories have all started overtime and overtime modes to cope with the surge in orders.

Whether it is an ordinary bicycle, or an electric car or an electric scooter derived from it, the frame is indispensable. The frame of a bicycle usually undergoes processes such as mold, machining, and assembly, and finally mass production is achieved. In recent years, in order to meet the design requirements of the mid-to-high-end market and reduce cost, laser processing technology has been gradually introduced into the bicycle frame manufacturing process.

At present, bicycle frames are made of pipes, and the use of pipes as bicycle skeletons has the following two advantages: first, lighter weight; second, higher strength. The laser tube cutting machine is precisely a special machine tool that uses laser cutting technology to perform various graphic cutting or hollowing on pipe fittings and profiles. It is a high-tech product that combines CNC technology, laser cutting and precision machinery.

Compared with the traditional cutting process indicators, the cutting section of the pipe processed by the laser cutting machine is smoother, and can be directly used for welding without secondary grinding. Compared with the traditional pipe processing, which requires cutting, punching and bending, the traditional pipe processing technology consumes a lot of molds. Laser cutting pipe has fewer additional processes, high efficiency, better quality of the cut workpiece, and high material utilization rate. It can be said to be the "gospel" of the bicycle manufacturing industry.

It has the special function of "throttling" for bicycle manufacturers:

●Millimeter-level cutting accuracy, high material utilization rate, less waste, and more material cost savings;

● High flexibility, can process various complicated shapes of bicycle materials, saving equipment investment costs;

● It can cut several meters of pipe in one minute, which is time-consuming, short and efficient, and can be processed in batches, saving the production time and cost for the enterprise;

● Automatic loading and unloading, automatic calibration and detection, automatic cutting after programming, general workers can be employed after training, saving labor costs.
