Preface is in the treatment of blade, the treatment difficulty of big lamina is the greatest, mastered the machines difficulty measure that solves big lamina, be opposite not only big lamina itself, and also have very positive effect to moving leaf, Jing Xie, guide vane and last years to wait. Difficulty of big lamina treatment has the following 3 respects: Mill craft shroud is in; Xie Gen's treatment; Aperture of mill lacing wire. Because the reason with 1 difficult treatment is big the material of blade is forging character, the molded lines part of forging and manage spell have difference, alloy of so low melting point irrigates the molded lines space block that give cannot with be identical of each lamina photograph, when treatment, go up, after next pressing plate impaction, the clearance between blade molded lines and molded lines space block makes the molded lines after treatment is out of shape, shroud manages size control flabby, cause discard as useless. The treatment that Xie Gen manages is the difficulty in blade treatment, because molded lines is complex, claimed accuracy is tall, because this is the place that handlers has a headache all the time, especially the fork of big lamina Xie Gen, have the precision problem of itself not only, have the metabolic problem that be released because of stress and poses more. Give fork when treatment model hind, because those pulls the disappear and causes contraction stress monotonicity of stress here, make Xiegen happening is out of shape thereby, if stress is very great, discarding as useless avoid hard, the loss that causes because of this every year is not small also. The processes occurrence difficulty account of lacing wire aperture, because Xie Gen is out of shape,be partly greatly very differ, cause radius not coincide, those who cause position of lacing wire opening is fluctuant, produce waste product thereby, on the other hand, because molded lines is out of shape, make the clearance of molded lines space block and molded lines and be out of shape badly of generation cannot be identical, it is the main reason that produces waste product, visible, difficulty (C) is shirt-sleeve difficulty (A) , (B) the unity of two kinds of blemish, if difficulty (A) , (B) has been solved, criterion difficulty (C) can be solved. Graph the means of settlement that place of shroud of craft of mill of 2 means of settlements encounters difficulty: The basis decided a gleam of at 2 o'clock, two lines decide the principle of one plane, designed form of a minute of buy adjustable tool, because use 3 thimble fixed position, because this is adjustable,type device is feasible. If right plan institute is shown. Specific operation method: Will big lamina is put, make the left and right sides is propped up separate, irrigate alloy of low melting point, 6, 4 all lock up dead. When discovering occurrence clearance, loose 6, 4 adjust 3 make when rising not to have clearance, the lock is dead 4, 6 begin to machine afresh. Control which respect clearance no matter, can assure line contact (with molded lines) , assure the surface contact with blade thereby, what cause as a result of clearance need not worry to be out of shape when such treatment. Tool is handy make easily, the operation is convenient, use it is easy to rise, apply the big blade that has space at those molded lines and academic molded lines to be able to reduce percent defective especially (this working procedure) 80% above. Xiegenjia is versed in place encounters the means of settlement of difficulty: The method that artificial effectiveness for a given period of time takes before Xiegenjia is versed in goes to Xiegennei's stress as far as possible much, had solved partial problem on certain level so -- , stress is out of shape. Face treatment itself to ask handlers. Adopt be opposite with dial gauge the means of the knife, is not to use dial indicator to workpiece, make 3 knives are in proper place, requirement craft also divides thick, precision work in finish machining, last knife make uniform, avoided to secure a face so big and the error of generation. The means of settlement of problem of difficulty of aperture of mill lacing wire -- school form: Solve as a result of what Xie Gen machines a problem, decreased to answer with, the Xie Gen when making machine lacing wire aperture thereby locates basic captain is accurate, the rest of the problem that the problem is the clearance between the molded lines in how solving treatment and molded lines space block. When the worker is being machined, adopt the method of mat commonly, but because machine the vibration of opportunity bed, make fill up content to often fall off, appear discard as useless, because this molded lines has position intention to cannot rise at will,fall at the same time, because this is used,solve (the method of A) problem also is no good, for this, can consider only from blade itself. Before machining this working procedure craft should machine a working procedure -- , school form, be about to the power of molded lines choose and employ persons that those and academic molded lines have discrepancy or mechanical power make with be identical of photograph of academic molded lines. For this, need measure of form of a school, the measurement that adopts model namely examines the flat circumstance with each sectional archives, it is normal to adopt arrange inflict manpower or mechanical power to reach its twist reach its twist thereby circumstance. 3 last words solve measure 3 kinds through adopting above, the problem that makes big lamina is machined can get basic settlement, plant for domestic other the treatment of blade provided academic basis, accumulated valuable experience.
