Transmission of hydraulic cutting machine: it is the hydraulic oil as the working medium, through the power element (oil pump) the mechanical energy of motivation into hydraulic oil, and then through the control element, then with the execution element (oil cylinder or oil motor) will convert the pressure into mechanical energy, drive the load to realize straight line or rotary movement, and through the control element remote control and adjust the flow, adjust the force and speed of the execution element. In the cutting machine, when the outside world disturbs the above system, the output of the execution element generally deviates from the original adjustment value, producing a certain error.
Hydraulic control: Like hydraulic transmission, the system also includes power components, control components and actuator components, and also transmits power through oil fluid. The difference is the hydraulic control with feedback device, the role of the feedback device is execution element output (displacement, speed, force and other mechanical quantity) feedback back and input (can change, can be constant) comparison, with the deviation control system, make the output of the execution element with the input change or keep constant. It is a hydraulic transmission system of closed loop, also called hydraulic servo system or hydraulic servo system.
The transmission system of the hydraulic cutting machine is used with the on-break or logical control element. For its control purpose, it is to maintain the stable or simple changing direction of the adjusted value, and the cutting machine is also called the fixed value and sequence control element.
The hydraulic control system is used in servo control elements, with feedback structure, and electrical device for control, high control accuracy and response speed, the controlled pressure and flow often change continuously. The output power can be amplified.
Proportional control is a kind of control between the above two, the proportional control valve is a new type of electro-hydraulic control element developed on the basis of on-off control elements and servo control elements, both has some characteristics of the two types of components, used for manual on-off control can not meet the requirements, but also do not need the servo valve as strict pollution control requirements for hydraulic system.
Inquiry on whether the fully automatic cutting machine will replace the hydraulic cutting machine
The cutting machine equipment with high degree of full automation are: computer controlled moving head cutting machine, laser cutting machine, high pressure beam cutting machine and computer cutting machine. In addition, Italian and British USM produce a projection cutting machine with oscillating tools and visual observation devices to scan the leather, or projection on the leather to guide the cutter to arrange the set of the cutting sample on the leather.
With the continuous improvement of modern science and technology level, the cutting machine industry continues to develop, the technology continues to improve, and the product is more and more advanced. Moreover, the cutting machine is an indispensable equipment in some light industries. The progress of cutting machines will help enterprises to improve the level of automation
In the traditional concept, the cutting machine is a machine that cuts and processes the material with the help of the acting force of the machine movement. However, some changes have taken place in the modern cutting machine, and the advanced technology such as high pressure beam and ultrasonic have been used in the leather cutting technology, but people still summarize these equipment in the equipment of the cutting machine.
Mechanical transmission of the cutting machine, although there are manufacturers continue to produce production, some small, individual manufacturers are still in use, but this form of cutting machine is bound to be eliminated. Hydraulic transmission of the cutting machine, now is still in the mainstream position. In the hydraulic cutting machine, a large number of what is used is the tonnage in 14-18 tons of the rocker arm cutting machine. Flat plate and gantry cutting machines are mostly used in relatively large manufacturers, more suitable for cutting artificial materials. The fully automatic cutting machine has been used in China. Due to the improvement of the modernization degree of the manufacturing industry, there may be a certain market in the near future. But in the near future, it will be impossible to replace the hydraulic cutting machine.
