2、lets that have to be cut are placed on the material table by a hall crane. 需要锯切的坯料通过天车放置到原料台架上。The table is executed so that max 40 tons of work pieces with a max diameter of 370 mm and a length between 5000 and 10500 mm can be placed on it. 台架应能够放置最重40吨，最大直径为370mm，长度在5000至10500mm之间的工件。The work piec
3、es are placed on the inlet roller table separately by an automatic handling device. 采用自动装卸装置将工件逐根放置到上料辊道上。After a safety and smoothly positioning on the inlet roller table, the driven rollers transport the material into the area of the material feeding tongs. The material feeding tongs are responsib
4、le for the exact length positioning of the bars. 在经过上料辊道上的安全平稳定位后，驱动辊道将坯料移到原料喂料钳区域。喂料钳负责对坯料进行精确定尺。After an exact positioning of the material by the feeding tongs in the sawing machine, the cutting process can start.在锯机上通过喂料钳对坯料进行精确定尺后，将启动锯切工序。The cut work pieces will be removed by a tong system in t
5、he outlet, which transports the work pieces from the clamping area to the deposit station for the work pieces. The scrap pieces will be removed by the tong system too, but these pieces will be disposed at the scrap piece flap. 锯切后的工件通过出口处的夹钳装置从夹持位置移到工件收集站。夹钳装置同样将废钢移走，但是这些将在废钢挡板处进行处理。2.2 Technical de

7、max weight of 40 tons and a max diameter of 370 mm can be placed. The material deposit table is designed with a width of 2,5 m and a length of 10,5 m but the maximum weight, which can be place on it, is 40 tons. 带装卸装置的原料台架为镇静钢结构，在其上可以放置最大重量40吨，最大直径370mm的坯料。收集台架设计为2.5m宽，10.5m长，但是其上可以放置的最大重量为40吨。The h
8、andling device always places the front work piece on the inlet roller table. In doing so all placed work pieces will be clocked one position forward. 装卸装置总是将前面的坯料放到上料辊道上。这样做可以保证所有的坯料在一个位置上向前移动。The handling device lifts the work pieces from the material table and transports it to the roller table rol
9、lers of the inlet roller table. The complete cycle happens fully automatically. 装卸装置将坯料从原料台架上提升移动到上料辊道上。整个循环是全自动的。The lifting movement of the handling device happens by a hydraulic system. 装卸装置的提升动作通过一个液压装置来完成。2.2.1.2 Inlet roller table 上料辊道The inlet roller table, which is manufactured as a solid st
10、eel construction, is equipped with driven rollers for the transport of the work pieces. These rollers are individually driven by a gear motor and beared in roller bearings. 由镇静钢结构制造的上料辊道配备有驱动辊，以实现运输工件。这些辊子通过齿轮马达单独驱动。The rollers transport the billets into the area of the material feeding tongs.这些辊子将坯
11、料运输到喂料钳区域。2.2.1.3 Material feeding tongs喂料钳The material feeding tongs drive on guidings, which are mounted on the substructure of the material feeding tongs. The guidings are absolutely free of maintenance. 喂料钳驱动导卫装置。导卫装置也安装在喂料钳的底部结构上。导卫装置是免于维修和保养的。For the feed drive we have foreseen an AC servo mot
12、or with gear and pinion, which engages with a toothed rack, which is also mounted on the roller table. The feed drive is executed free from backlash. 应有一个带齿轮齿杆的交流伺服电机来驱动喂料设备，它与一个齿条啮合。齿条也固定在辊道上。喂料驱动运行过程中不会后退。The length tolerance amounts to 1,0 mm. 长度误差为 1,0 mmFor the clamping of the work pieces with
13、the material feeding tongs is a hydraulic cylinder foreseen. 为了用喂料钳夹住坯料，应配置一个液压缸。The complete feeding tongs are executed floating, that means also with bent work pieces the material feeding tongs float in vertical and also in horizontal direction. 整个喂料钳是可以浮动的。这意味着处理弯曲工件时，喂料钳可在垂直和水平方向浮动。The material
14、feeding tongs are executed as a solid steel construction. 喂料钳是由镇静钢制造的。Intended travelling way: approx. 5,5 m设计行程：5.5m2.2.1.4 Chip conveyor 锯屑输送机The chip conveyor transports the chips into a container outside of the sawing area (The chip container is not included in MFLs scope of supply).
