济南推拉蓬工程上的打孔操作

来源:http://www.sdcscp.com/ 日期:2021-03-29 发布人:admin

济南推拉蓬工程在我们的日常生活中应用非常广泛。在焊接结构中,钢的焊接收缩和变形是不可避免的。因此,在生产过程中,抓牢什么时候开孔会大大影响整个材料的精度。
Jinan tugabong project is widely used in our daily life. In welding structure, welding shrinkage and deformation of steel are inevitable. Therefore, in the production process, grasping when to open a hole will greatly affect the accuracy of the whole material.
那么,你对钢结构工程加工中的开孔工艺了解多少呢?
So, how much do you know about the opening process in steel structure engineering processing?
对于济南推拉蓬工程的柱结构和梁结构的施工,钢连接孔组尺寸精度直接影响钢结构工程的安装精度。把握好开门时间是非常重要的。组装、焊接、变形修正完成后,另一端钻孔。济南推拉蓬工程构件加工时,孔位应提前标注。组装、焊接、变形校正完成后,进行钻孔标识确认。
For the construction of column structure and beam structure of Jinan tugabong project, the dimension accuracy of steel connection hole group directly affects the installation accuracy of steel structure project. It is very important to grasp the opening time. After assembly, welding and deformation correction, the other end is drilled. The hole location should be marked in advance when the components of Jinan tugabong project are processed. After assembly, welding and deformation correction, drilling identification shall be confirmed.
变形修正后,我们需要对钢材的端面进行精加工,然后我们就可以在精加工的表面上画线打孔了。打标时考虑焊接收缩、变形余量和允许公差,直接钻孔。机械钻孔有电钻、风钻、立式钻床、摇臂钻床、桁架摇臂钻床、多轴钻床、数控钻床。
After deformation correction, we need to finish the steel end face, and then we can draw lines and punch holes on the finished surface. When marking, the welding shrinkage, deformation allowance and allowable tolerance shall be taken into account, and the holes shall be drilled directly. Mechanical drilling has electric drill, pneumatic drill, vertical drilling machine, radial drilling machine, truss radial drilling machine, multi axis drilling machine, CNC drilling machine.
有时需要用气体打孔。我们使用的比较简单的方法就是在设备的气割喷嘴上安装一个简单的附件装置,可以打一个φ30的孔。用夹具和叠板钻孔。这是一种钢结构工程钻孔方法,目前在国内还未普及。用夹具固定,钻套采用碳钢或合金钢制造。钻孔模板上下平面平行,偏差不大于0.2mm。
Sometimes it is necessary to punch holes with gas. The relatively simple method we use is to install a simple accessory device on the gas cutting nozzle of the equipment, which can make a hole of φ 30. Drill holes with clamps and laminations. This is a kind of drilling method for steel structure engineering, which has not been popularized in China at present. The drill sleeve is made of carbon steel or alloy steel. The upper and lower planes of the drilling template are parallel, and the deviation is not more than 0.2mm.
钻孔套筒应垂直于钻孔模板平面,偏差不得大于0.15mm。整体钻模制造的允许偏差应符合有关规定。所有零件的加工和生产都是非常重要的,想要获得济南推拉蓬良好的加工质量,就需要控制孔的制作工艺。希望本文的介绍能对您有所帮助。
The center of the drilling sleeve shall be perpendicular to the plane of the drilling template, and the deviation shall not be greater than 0.15mm. The allowable deviation of integral jig manufacturing shall comply with relevant regulations. The processing and production of all parts are very important. In order to obtain good processing quality, we need to control the hole manufacturing process. I hope the introduction of this article can help you.
