The impact of poor machine accuracy can be experienced by all users, low efficiency: the main performance is often cut constantly phenomenon or the middle can cut around the cutting constantly, the need to use a knife or scissors to cut off, which also greatly reduce the work efficiency; Cutting pad consumption is too fast: after cutting for a period of time, the middle of the pad or a certain position is receded in advance, the pad is scrapped in advance, which increases the production cost invisibly; Die is easy to break: often a die is broken without reason.
The control of reducing precision error is divided into two parts: manufacturers and users: manufacturers mainly from improving the machining accuracy and do a good job in the whole process of strict control; As a user is mainly to do a good job of automatic cutting machine daily maintenance and other work.
The general users of hydraulic technology of cutting machine should try to choose the required hydraulic station from the existing hydraulic station products according to the main engine function structure, working condition type, condition and relevant requirements, in order to save equipment investment and shorten the manufacturing cycle. Typical products of hydraulic station. If the existing hydraulic station products can not meet the use of the requirements, you can design and manufacture hydraulic station according to the relevant information.
The assembly system of various hydraulic valves and their auxiliary connectors is called hydraulic control device (hydraulic valve group), and the assembly system of hydraulic pump and its driving motor and fuel tank and its accessories is called hydraulic power source device (hydraulic pump station). The assembly of these two parts is called the hydraulic station assembly. The integration of the hydraulic valve group and the design of the hydraulic pump station can also be combined with the engineering design practice proves that most of the work in the design of the whole hydraulic device is concentrated in the integrated design of the hydraulic control device.
The design of the hydraulic system of the cutting machine refers to the composition of a new energy transfer system to complete a specialized task. The hydraulic system of cutting machine is divided into transmission system and control system. There is no essential difference between the structure composition and working principle of the two. The main difference in design content lies in that the former focuses on static performance design, while the latter includes dynamic performance design in addition to static performance. In general, the design content and method of hydraulic transmission system can be directly used in the design of hydraulic control system as long as a little adjustment.
The design of the hydraulic transmission system is closely related to the design of the main engine, and the two are often carried out simultaneously. The designed hydraulic system should firstly meet the requirements of drag and circulation of the main engine, and secondly meet the accepted design principles of simple structure, small volume, light weight, safe and reliable work, convenient operation and maintenance, and good economy. In the actual design work, the pursuit of efficiency and the pursuit of safety are often combined. Due to the different requirements of various host devices on the system and the amount of designers' experience, some contents and steps can be omitted and simplified, or some contents and steps can be combined and crossed.
