c型钢结构杆件加工的注意事项有哪些?

济南彩钢瓦c型钢结构需机加工的钢构件应重视在未加工前杆件的质量,操作者必须坚持做好以下工作。

Jinan color steel tile C steel structure needs to be machined steel members should pay attention to the quality of the bar before machining, the operator must adhere to the following work.

一、在钢结构杆件未加工前,巡查需机加工杆件的平、直和扭曲变形是否在标准要求范围之内,超标变形件应拒收。操作者不可只顾埋头加工而忽视了机加工件本身存在变形超标的问题。

1、 Before the steel structure member is machined, inspect whether the flat, straight and twisted deformation of the bar to be machined is within the standard requirements, and the parts with excessive deformation shall be rejected. The operator should not only pay attention to the machining and ignore the problem of excessive deformation of machined parts.

钢结构加工件本身存在不平、不直和扭曲超标变形,会致使加工铣、刨的面不能使用。因此,必须坚持做好在未加工前对机加工件的质量复核(审查核对)工作。

The uneven, non straight and distorted deformation of steel structure processing parts will cause the milling and planed surface can not be used. Therefore, we must adhere to the quality review (review and check) of machined parts before machining.

二、机加工工件加工基准线的确定,上道工序已规定机加工的基准线(已冲样冲印),应与上道工序取得确切加工总长度尺寸,然后操作者亲自复核(审查核对),认可基准线与基准线之间总长度尺寸后,进行加工,如上道工序只告知机加工工序经机加工工序经机加工后的总长度尺寸,操作者应自求基准线,操作者应由加工件毛坯总长度中间部位往加工件两端部量所需尺寸求得机加工基准线。不允许以毛坯加工件毛面为依据量机加工基准线,因毛坯加工件的毛面凸凹不平,无法依此确定任何边、面。

2、 For the determination of machining datum line of machining workpiece, the datum line of machining has been specified in the previous process (the sample has been punched and printed), and the exact total processing length size shall be obtained from the previous process, and then the operator shall personally review (check) and confirm the total length between the reference line and the reference line before processing. The above process only tells the machining process that the machining process has been machined The operator should calculate the datum line by himself for the total length after construction. The operator should measure the required size from the middle part of the total length of the workpiece to the two ends of the workpiece to obtain the machining reference line. It is not allowed to measure the machining datum line based on the rough surface of the blank workpiece, because the rough surface of the blank processing part is uneven, it is impossible to determine any edge or surface according to this.

三、钢结构机加工前,首先将加工件就位于机加工胎架上并紧靠胎架定位靠件与机加工刀面成90度,确认无误后采用工夹具将加工件与机加工胎架夹紧固定。

3、 Before machining the steel structure, first place the workpiece on the machining jig frame and position it close to the jig frame. The backup part and the machined tool surface should be at 90 degrees. After confirming that there is no error, the fixture is used to clamp and fix the workpiece and the machining jig frame.

四、启动加工时必须注意,操作者及周围安全防护工作做到位,当机刀切削受力时应巡查已固定的加工件是否有异常,发现问题及时解决,机刀进刀量不宜过多,必须按机加工标准操作,否则经机加工后的端面精度(度)达不到标准要求。

4、 When starting machining, the operator and the surrounding safety protection work should be in place. When the machine tool is under cutting force, it is necessary to inspect whether the fixed processing parts are abnormal. If the problems are found, they should be solved in time. The feed amount of the machine tool should not be too much. It must be operated according to the machining standard, otherwise the end face precision (degree) after machining can not meet the standard requirements.
