Small compression of hydraulic presses and stable transmission are advantages

       The hydraulic press adopts a self-developed double dead-cycle servo system control method, which is highly user-friendly, full-process automatic, intelligent and powerful. Hydraulic press, hydraulic skills and their influence hydraulic skills are the key foundation skills to complete modern transmission and control One of them has become an important technical foundation for industrial machinery, construction machinery and the world's top products. It is their key skills for the direction of  automation, high precision, high efficiency, high speed, miniaturization and light weight. Industrial developed countries have listed the hydraulic industry as a competitive occupation, and its development speed is much higher than that of the machinery industry. Hydraulic components and their manipulation have developed into comprehensive hydraulic engineering skills. Machinery manufacturing is an industrial sector that provides advanced skills and equipment for various sectors of the national economy and its own technological transformation. Casting, forging, welding, FRICTION SCREW PRESS heat treatment, and cutting are important production methods for the machinery manufacturing industry to obtain blanks, formed products and improve the mechanical functions of parts. Hydraulic skills are widely used in many cold and hot metal processing machines and equipment, among which presses and metal Cutting machine tools are an earlier and wider field of using hydraulic skills. In the hydraulic machine tools of turning, milling, planing, grinding and drilling, the first step is to use hydraulic skills to perform stepless speed regulation in a wide range.PUNCHING PRESS  It has outstanding reversing and switching functions, and it is easy to complete the advantages of working cycles. Workpiece and tool clamping, control feed speed and drive spindle operation, although modern CNC machine tools, machining centers and other advanced production equipment use electric servo system, but the use of hydraulic transmission and control is still an important way to automate modern metal cutting machine tools .FIXED TABLE PRESS

　  Advantages of hydraulic transmission Smooth transmission In hydraulic transmission equipment, because the hydraulic oil has a very small contraction amount, it can be assumed that it cannot be contracted under normal pressure, and the transmission depends on the successive activities of the oil. The oil has the ability to absorb vibration, and hydraulic buffer equipment can also be installed in the oil circuit. Therefore, unlike the mechanical organization, processing and installation errors will cause oscillation and knocking, which makes the transmission very stable and facilitates frequent commutation; therefore, it is widely used Used in machinery that requires smooth transmission, for example, all grinders use hydraulic transmission. Light weight and small size Compared with mechanical, electric and other transmission methods, hydraulic transmission can reduce a lot of volume PUNCHING AND FOLDING MACHINE  and mass under the condition of the same output power, so the inertia is small and the movement is flexible; this reduces the requirements for hydraulic profiling, hydraulic active control and requirements The quality of the machine is particularly important. For example, the 1m excavator produced in my country has reduced the mass by 1t compared with the mechanical transmission after using hydraulic transmission. With great carrying capacity, hydraulic transmission is easy to obtain great force and torque, so it is widely used in limiting machines, tunnel boring machines, steering gears for ships with 10,000 tons and hydraulic presses with 10,000 tons. Simple completion of stepless speed regulation In hydraulic transmission, the flow of the conditioning liquid can complete stepless speed, and the speed scale is very large, up to 2000:1, which is very simple to achieve extremely low speed. Easy to complete overload maintenance. Many safety maintenance measures have been taken in the hydraulic system to actively DEEP THROAT PRESS prevent overload and prevent trouble. Hydraulic components can be actively lubricated. Because hydraulic oil is selected as the working medium, the hydraulic transmission equipment can be actively lubricated, so the components have a long service life. . Simple and chaotic action Selecting hydraulic transmission can achieve various chaotic mechanical actions, such as the hydraulic profiling tool post of profiling lathes and the hydraulic working table of CNC milling machines, which can process irregular-shaped parts. Simplify the organization of the graduation project (thesis) of Harbin Institute of Technology Huade School of Skills to facilitate the completion of the automated hydraulic system, the pressure, flow and direction of the liquid are very simple to control, coupled with the coordination of electrical equipment, it is very simple to complete the messy initiative Operating cycle. Now, hydraulic transmission is widely used in modular machine tools and driving lines.
