加热炉板坯称重和对中装置液压系统是当前工厂中流水线生产重要的运输装置之

Heating furnace slab weighing and centering device hydraulic system is one of the important transportation devices in the current production line of the factory, which can not only quickly lift the goods, but also automatically center the goods to prevent falling. The topic of my research and design this time is-heating furnace slab weighing and hydraulic system design of the centering device. To start this graduation project, I need to consider the following two aspects: First, the mechanical aspect, we are the cylinder to push the mechanical device To exercise as much as possible, in this process, we need to calculate and select the selected rack and pinion device and slab scale device, and then perform performance check calculation. The second is the hydraulic system, you need to consider the overall system diagram first, then draw the diagram, use cad to draw the required hydraulic graphics. In designing hydraulics, the system principle involves circuit problems. I divide the circuit into three circuits. These circuits are commonly used in the system. For the unloading circuit, I use a pilot-type relief valve and a remote unloading device to unload the system, which can reduce losses and unload efficiently. The centering part of the locking circuit uses a two-way hydraulic lock locking circuit. The downward hydraulic lock is used to lock the circuit; the speed control circuit I use a two-way speed control circuit for speed regulation of the weighing and centering circuit. For the system selection, after the design of the circuit and the selection of mechanical components, I chose the system as an open system, because the open system has the advantages of low cost, smooth system and high efficiency. The selection of mechanical components in the system can be designed according to standard components, and other non-standard components can be selected based on hydraulic components and mechanical design. After the initial definition, the model of the component I selected is as follows: the hydraulic cylinder is selected as

加热炉板坯称重和对中装置液压系统是当前工厂中流水线生产重要的运输装置之一，不仅可以快速的提升货物，还能将货物自动对中，防止掉落。而此次我研究设计的题目就是—加热炉板坯称重和对中装置液压系统设计，着手这个毕业设计，我需要以下两个方面来进行考虑：一是机械方面，我们是缸推动机械装置尽兴运动，在这过程中那我们需要对选择的齿轮齿条装置和板坯秤装置进行计算、选型，之后再进行性能验算。二是液压系统方面，需要先考虑总的系统图，之后绘制图，用cad画出需要的液压图形。在设计液压方面途中，系统原理会涉及回路问题，我把回路主要分为三个回路这些回路都是系统中常用。卸荷回路我采用先导式溢流阀加远程卸荷装置进行系统卸荷，既能减少损耗也能高效率卸荷；锁紧回路对中部分我采用双向液压锁锁紧回路，称重部分我采用下行液压锁紧锁紧回路；调速回路我对于称重和对中回路都采用双向调速回路进行调速。对于系统选择，通过回路的设计和机械元件的选择后，我把系统选择为开式系统，因为开式系统具有造价便宜、系统流畅、效能较高。系统中机械元件的选择，可按标准件设计的按标准件设计，其他非标准件则按液压元件和机械设计上面选型设计。初步定义后，我选择的元件型号如下：液压缸选择为

The hydraulic system of slab weighing and centering device of reheating furnace is one of the important transportation devices in the current production line of the factory. It can not only quickly lift the goods, but also automatically align the goods to prevent falling. The topic of my research and design this time is the design of slab weighing and centering device hydraulic system of heating furnace. To start this graduation design, I need to consider the following two aspects: one is the mechanical aspect, we are the cylinder to push the mechanical device to move to the fullest. In this process, we need to calculate and select the gear rack device and slab weighing device, and then we will Check the performance. Second, in the aspect of hydraulic system, it is necessary to first consider the general system diagram, then draw the diagram and use CAD to draw the required hydraulic diagram. In the design of hydraulic system, the principle of the system will involve the circuit problem. I divide the circuit into three main circuits which are commonly used in the system. In the unloading circuit, I use the pilot relief valve and remote unloading device to unload the system, which can not only reduce the loss but also discharge the load efficiently; in the middle part of the locking circuit, I use the two-way hydraulic locking circuit, in the weighing part, I use the down hydraulic locking locking circuit; in the speed regulating circuit, I use the two-way speed regulating circuit for the weighing and the middle circuit. For system selection, through the design of the loop and the selection of mechanical components, I choose the system as an open system, because the open system has low cost, smooth system and high efficiency. The selection of mechanical components in the system can be designed according to the standard components, and other non-standard components can be designed according to the hydraulic components and mechanical design. After the preliminary definition, I choose the following component models: hydraulic cylinder is selected as<br>
