我们对标准节在塔吊中的作用都了解多少呢?下面由小编简单分享其加工工艺工序及其中组焊标准节的工艺步骤:
How much do we know about the role of the standard section in the tower crane? The following is a brief summary of the technical process and the standard procedure of the welding standard section:
焊装模具是卧式的,模具的两块支板可以旋转,便于焊装时操作。标准节的立柱、方框、导轨、齿条均可在此焊装模上一气呵成。焊装工序如下:
The welding mould is horizontal, and the two supporting plates of the mould can be rotated, which is convenient for welding operation. One standard section column, box, guide and rack can be realized in the welding die. Welding procedure is as follows:
1、装夹好2根立柱,以立柱管两端的圆柱孔与端面定位,通过顶紧螺杆夹紧。
1, the installation of a good column of the column to the column at both ends of the cylindrical hole and the end of the positioning, through the top screw clamping 2.
2、用辅助卡板确定方框位置,点焊三个方框以及腹杆。
2, with the auxiliary board to determine the position of the box, spot welding three boxes and abdominal.
3、点焊导轨。将加工好的角钢嵌入导轨定位轴的糟中用顶紧螺杆夹紧,点焊。
3, spot welding guide rail. The processed angle steel is inserted into the guide rail positioning shaft to be clamped by the top screw.
4、安装齿条。事先将垫块与齿条紧固通过齿条两端的销孔将齿条固定齿条定位销上,用顶紧螺杆夹紧,将与齿条紧固的垫块点焊在方框上。
4, install rack. In advance, the pad and the rack are fixed through the pin hole at the two ends of the rack, and the rack is fixed on the positioning pin of the rack.
5、检查各尺寸无误后,对各部分施焊。标准节焊成后,旋转各顶紧螺杆,将各夹紧装置向右推出,从而吊离焊装模。
5, check the size of the correct, the various parts of the welding. After the standard section is welded, the top fastening screws are rotated, and the clamping devices are pushed to the right.
对于质量的要求是重点,为了能够加工出高品质的产品,必须对焊装模的制作严格遵守:
For the quality of the requirements is the key, in order to be able to process high quality products, must strictly adhere to the production of welding mold:
1、支板的内侧面为标准节端面的定位面,为了保证标准节升降平台的平面度定位面进行金加工。
1, the inner side of the support plate for the standard section of the end of the positioning surface, in order to ensure that the standard section of the lifting platform for the positioning of the plane surface of the gold processing.
2、两支板对应孔的同心度大小将影响标准节的焊装精度,因此膛孔时,两支板应装夹成一体同时撞,以提高同心度。
2, the size of the concentricity of the two plates corresponding to the hole will affect the welding precision of the standard section, therefore, when the bore hole, the two plates should be clamped into a whole at the same time, in order to improve the concentricity.
3、为了减少焊接变形,便于拆卸,凡有滑动面的配合不宜太松。
3, in order to reduce welding deformation, easy disassembly, all sliding surfaces with not too loose.

塔机标准节4、两支板的间距在满足装夹、拆卸的前提下,应尽量缩短。
4, the distance between the two plates to meet the requirements of clamping, disassembly, should be shortened as far as possible.
5、两块支板应选用较厚的钢板,如果条件许可,尽可能选用铸件,因为铸件的钢性较焊件好,热膨胀系数较碳钢小。
5, the two plates should be used to choose a thicker steel plate, if the conditions permit, as far as possible the use of castings, as the casting steel better than the weldment, thermal expansion coefficient smaller than carbon steel.
