Description

Technical Field

[0001] The present application relates to the field of generator set positioning rib processing, and in particular to a large generator set positioning rib blanking and cutting device. Background Art

[0002] The positioning rib is an indispensable component in the generator stator, used to hang and fix the generator stator core. The positioning rib finished product is generally a slender workpiece with a length of 5 to 8.5 meters and a cross-sectional area of ​​80mm×70mm. After processing, it is necessary to use a template to test the appearance and use a straight ruler to check the straightness of the positioning rib. The straight ruler length should not be less than 1m, and the 0.08mm feeler gauge should not enter the inspection range. Therefore, high precision is required. We must grasp every process well. The production process of positioning rib is generally steel plate incoming material → non-destructive testing → blanking → heat treatment to relieve stress → straightening → rough processing → natural failure → semi-finishing → non-destructive testing → Finishing → Protection → Storage, where the incoming steel plate thickness is 100mm and the cutting is flame cutting; the raw materials for positioning ribs are generally steel plates cut by flame cutting. The materials must be stress relieved and annealed after cutting to avoid the influence of thermal stress of cutting on subsequent processing deformation and alignment, to ensure that the final delivered product will not cause irreversible deformation such as distortion due to stress release, to prevent the material performance from being adversely affected by the heat-affected zone of the cutting edge. The thermal cutting surface must retain a subsequent cutting processing allowance of ≥15mm, which wastes a lot of material, increases processing costs and heat treatment costs, and has a long processing cycle.
