Sales of water jet cutting machines in China in the first half of 2021

Affected by factors such as the significant increase in ocean freight, the sales of China's waterjet cutting machines in the first half of 2021 failed to achieve the expected target. Although the sales amount and volume increased over the same period last year, there was no major breakthrough.

At the same time, China water jet cutting machine are also developing in the direction of higher-end, smarter, more energy-efficient, and more functional, such as five-axis 3D cutting technology, ceramic tile production lines, and the wider application of servo direct-drive pumps.

Как выбрать рабочую платформу с числовым программным управлением и систему водонагревателя высокого давления?

В реальном процессе эксплуатации условия отличаются, то есть из-за различных условий работы соответствующие параметры, необходимые для соответствующей обводненности, также различны. Это также затрудняет сборку оборудования для гидроабразивной резки, будь то рабочая платформа с ЧПУ или система высокого давления, она должна соответствовать окружающей среде.
Прежде всего, рабочая платформа с числовым программным управлением для оборудования для резки воды, в этом отношении существует два варианта: одна рабочая платформа с числовым программным управлением консольного типа, а другая - рабочая платформа с числовым программным управлением портального типа, каждая из которых имеет свои характеристики. Механизм движения первого и режущая платформа разделены и не влияют друг на друга; последнее как раз наоборот.
Следовательно, в реальном процессе выбора это зависит от размера материала, который должен быть разрезан устройством для резки водой. Режущая платформа с ЧПУ консольного типа больше подходит для случая, когда размер материала нерегулярен, а режим загрузки и выгрузки не фиксирован.
Во-вторых, система высокого давления оборудования для гидроабразивной резки с ЧПУ, этот аспект также тесно связан с материалом, подлежащим резке. Разнообразие, толщина, качество поверхности резания и требования к скорости резания материала будут определять, какое оборудование для резки должно быть сконфигурировано. Система высокого давления.станок для гидроабразивной резки.
Например, если это высоковольтная система с напряжением 300 МПа, ее можно использовать для резки твердых материалов толщиной менее 30 мм. Однако, если материал относительно твердый, необходимо использовать систему высокого давления 380 МПа. Он имеет преимущества с точки зрения способности резки, качества поверхности резки, скорости резки и тому подобного.водоструйный станок с чпу высокого давления.
Кроме того, другие дополнительные элементы для оборудования для резки водой, такие как обработка мягкой воды, автоматическая система подачи песка и т. Д., Одинаково важны для эффекта резки оборудования для резки водой и не могут быть проигнорированы.

Analysis of water jet cutter's characteristic and abrasive

Pressure on the depth of cutting:
Determined pressure and velocity of the water jet erosion energy, and its size is proportional to the water jet cutting ability. When high pressure, the machining tank side area, high efficiency, removing less; contrary, low efficiency, better quality; processing tank is too wide, it will result in waste of material. Different types and thickness of material being cut, the pressure corresponds to a certain limit, the case where only the water pressure exceeds the pressure value can be effectively cut. Often considered the best pressure is about 2.5 times the limit pressure value, then the pressure and the depth of cut is linear.

Nozzle traverse speed, but also have a greater influence on the surface quality of the processed material. With the increase of the traverse speed, the cutting capacity per unit area decreased, increasing the surface roughness of the material, particularly when the traverse speed reaches a critical value, the machined surface roughness increased dramatically. The size of its critical value and the abrasive nature of the greater impact.

Why does the nozzles of water jet cutting machine consume too fast?

The water jet cutting machine consumption mainly include two parts: the nozzle and garnet gems . The consumption of pomegranate sand basically every waterjet manufacturers are similar, but the jewel orifice consumption vary significantly . Some manufacturers may use 30 to 40 hours , and some manufacturers may even insist on less than 10 hours , the quality of the purchase gems nozzle itself is on the one hand, there are other reasons see below description.

First, the selection of water on water cutting, water jet cutting water used in the process , although less demanding , but still the best for the quality of the water has a control , the use of household water is the best choice, cost and purity of on it are possible .

Second, the purity of the sand on the pomegranate , pomegranate using abrasive waterjets is best to choose a more formal manufacturers purchase . Do not just seek a little money away can be cheaper to buy some of the poor quality of the garnet , which is generally inferior product filter impurities in order to save costs in the process , the sand particles have pomegranate requirements are not high , in the course of the gems of the nozzle the damage is great.

Third, on the cutting issue, different hardness, material thickness and is used when cutting pressure , etc., these are the choices have different degrees of damage to the jewel waterjet nozzle . For example, in the course of waterjet machining often high hardness, thickness of the workpiece and the long-term in the case of higher pressure so it is likely to cause jewel nozzle wear.

Finally, add a little oil straight shaft surface ( Sewing machine oil can be used , do not use oil ) , the laser head slowly pushing the lateral direction , so that repeated several times, so that lubricant evenly distributed in the straight shaft surface . ② the same way about cleaning and maintenance guide beam linear axis . B, carriage assembly ( metal guide wheel ) cleaning and maintenance , replacement : Cleaning and maintenance with a linear axis with the same method to clean and maintain carriage assembly ( metal guide wheel ) . Carriage assembly ( metal guide wheel ) is easy to wear , replace Precautions are: linear axes and adjust the carriage assembly ( metal guide wheel ) gap between the carriage assembly ( metal guide wheel ) in the linear axes When running on no block. Specific adjustment method , first adjust the carriage assembly ( metal guide wheel ) on the carriage assembly eccentric ( metal guide wheel ) wheel just touches the surface of a linear axis , the locking slide assembly ( metal Guide wheel ) screws , then tighten the eccentric set screws . 6 , timing belt, timing belt pulleys Belt and timing belt pulleys, is important mechanical transmission equipment parts , which controls the laser head trajectory. Belt running over time , prone to micro- stretching and loosening of variable length , So that the laser head movement accuracy and sensitivity have a great impact , so the drive belt timely adjustments. Adjustment method : the X to Y- belt adjustment , timing belt tensioner to be transferred to an appropriate level ; adjustment of the drive motor belt , which should generally be adjusted to the tightness of the central belt presses , its sinking amount Both ends of the pulley center distance preferably 3-5% . Note: a) If the adjustment of the belt too tight , the belt will not only easy to tensile deformation , but also accelerated bearing wear ; if too loose, then allowed transmission accuracy and sensitivity. So the tension on the belt Should be adjusted to the best condition. To adjust the Y- belt belt tension level when appropriate , and to both sides of the belt tension level consistent with the process so that the drive belt can be stable and will not affect the product 's engraving,laser cutting results. b) timing belt should be away from oil or chemicals , is strictly prohibited and acids, alkalis, oils and organic solvents. Timing belt should be allowed to remain dry and clean condition. c) there is a rubber belt problem of aging , if the belt rubber is aging ( or wear ) , must be promptly replaced with new belt , pay attention to the change of the timing belt with the belt round match. d) Pulley used for some time , there will be loose and wear phenomena , must be promptly replaced and tightened. To take note of the change of timing belt pulleys and belt to match . 7 , screws, fastening coupling Motion system working for some time , the movement of the screw connection , loose coupling is generated , it will affect the smooth mechanical movement , so to observe the operation of the machine there is no abnormal sound or drive components anomalies, Fastened to timely identify problems and maintenance. Over a period of time while the machine tool should be individually fastening screws . The first fastening device should be used in about a month after . 8 , the optical path of the inspection Laser engraving machine optical system is reflected by the reflection mirror and the focusing mirror finished common focus , the focusing lens in the optical path shift is not present , but three mirrors are fixed by the mechanical parts , the possibility of relatively offset large , Although not normally happen offset, but recommends that users be sure to check before each work light path is normal. Detailed Please refer to Chapter " optical alignment standards " 9 , sliding beams Slip beams as aluminum profiles , soft material , to prevent three-dimensional translation stage profiles and the upper surface of the contact plate scratch hard objects , keeping the flat upper surface and clean it regularly . 10 , three-dimensional translation stage Three-dimensional translation stage for fine adjustment of the position of the camera so that the product can quickly locate the working surface of the plate for cutting . Three-dimensional translation stage for long-term use , its three-dimensional slip Between the rails and easy rust dust will affect the use , it should be kept clean between the three-dimensional sliding rails and gauze moistened with anti-rust lubricant wipe the surface.
