Pay attention to the following five aspects when designing large -scale flanges:
1. The large -scale flange of the workflow design is made of 2 parts of the 900 -folding bottom plate, 2 flanges and 2 standing plates and 4 enhanced tendon group welding. For the rigidity of the work, the welded seam of the connected section should be welded through the slope, and the welding angle is 20-30mm. Drill the corresponding bolt holes on the flange board. The flange can be accurately connected with the bolts with the Francut Plate. There is a gap that can be placed in a small manual jack between the back of the small end Flag. The direction of the stand is on the flange board to open a gap in order to put the elbow into the workers and use thicker steel plates to make a similar groove -shaped structure, which can meet the rigid demand for rigidity during cutting.
2. The performance of the workstory requires that the two flanks of large flange are perpendicular to each other, and the workbench of the vertical lathe is horizontal. Frank is connected together. When the workpiece is clamped on the workbench, the flange plane that should be processed and the vertical lathe workbench should be concentrated and parallel. In order to reduce the number of workers, the installation should be able to change the position of the folder. On the 1st work, the elbow can be processed 2. Frank. At the same time, the tooling has sufficient rigidity, otherwise it will seriously affect the processing quality of the French sealing ring groove. Therefore, if it meets the usage, it should minimize the height of the workflow, so as to improve the stiffness and convenient operation. After fixing the large -scale flange, the radius of the turning radius should not exceed the working radius of the vertical vehicle, and it can be easy to adjust the clip, which is easy to adjust, and it is convenient for cutting into the knife.
3. The stiffness of the tooling of the groove of the groove of the groove -type cantilever bending and reversing when the stress model of the cantilever beam is cut. Through the above school nuclear, the deflection of 7.27 × LO-7M and corner 8.969 × 10-5 are all deformed, and reinforced reinforcement is added to the relevant parts. The rigidity is far exceeding the calculation value. After combining with the elbow flange, the diameter of the rotation is 2.42m <3.50m (dual -column standing diameter), so this workmanship is theoretically feasible.
4. When the large -scale flanges are processed and processed, the bottom plate is adjusted down on the vending workbench. The starting station can be cut together and parallel. When processing the small -term flange, put the bottom plate of the workshop, put it on the vending workbench, and use 6 manual small jacks to tighten the back of the small end flange and the small bracket plate. Only fix it with the small bracket board to cut the small flange. When cutting and finding the formal folder, the verticality of the flange should be performed.
5. The large -scale flangor work structure is simple and reasonable, convenient and rigidly manufactured. It is convenient to find positive adjustment operations during processing, which meets the three groups of elbow flange that needs to be processed on the upper vehicle processing of large elbows. In the future, under the condition that there are no end -facial processing machine tools, a new way is processed with similar components.
