Description
Technical field
The present invention relates to field of machining, be specifically related to winch master rotor processing method.
Background technology
A winch is all had in rig and workover rig, wherein there is the winch of Multiple Type perhaps, master rotor is parts on winch, be usually used in drilling well or well workover lifting operation, its crudy determines the serviceability of product, therefore reasonably dividing processing T sequence and formulate rational processing method, is the key that product quality reaches technical requirement.
Barrel is welded by connecting plate, stiffener, side plate, baffle plate and cell body, full accuracy is IT7 level, general machine tooling just can reach the required precision of its size, but there is the form and position tolerance at two places higher, processing not easily ensures: one is two ends size inner stoppers, also be two benchmark, dimensional accuracy is IT7 level tolerance, but its axiality requires very high, because inner stopper coordinates with tie-plate male half coupling, tie-plate is connected with main drum shaft by key, transmits power, if axiality can not reach requirement, main drum shaft just dress does not get on.So its axiality requires higher, this is a difficult point in processing; Another difficult point is be the male half coupling of two ends connecting plate, and it is connected with brake disc, and its axiality requires also high, requires also very high to axiality, and the perpendicularity in its shoulder face requires as 0.1mm; Also have operation many, welding and machined intersect to be carried out, and middle also have heat treatment step, if do not adopt rational process and processing method, is difficult to reach its Geometrical Tolerance Principle.
Summary of the invention
In order to solve the problem, the invention provides a kind of process simple, be easy to manufacture, and crudy and the dimensional accuracy of workpiece can be ensured, reducing production cost, the winch master rotor processing method of enhancing productivity.
Winch master rotor processing method of the present invention, comprises the following steps:
The first step, welding, on processing cell body, grooving and other size are to finished size, and connecting plate and side plate only process endoporus, and connecting plate end face stays allowance, and other size postwelding is processed; Processing is set to finished size, and wherein endoporus front end stays 15mm not process, and end face stays allowance, reprocesses after entirety is soldered; By connecting plate, stiffener and side plate and cover are welded as a whole;
Second step, turning, after fixing for said modules clamping on lathe, turner profile;
3rd step, welding, by said modules and baffle plate, cell body is welding as one;
4th step, heat treatment, stress relief annealing, to eliminate the rear residual stress produced of welding, in stress relief annealing process, weldment there is no tissue change, eliminates in the annealing process after residual stress is mainly incubated at 500 DEG C one 650 DEG C by weldment;
5th step, boring, workpiece adopts V-block to support, with location, cell body outer garden, calibration of workpieces end face is vertical with main shaft, then compress with pressing plate, tune boring is under workpiece once mounting, first bores one end inner stopper, then boring table is turned round 180 °, the inner stopper of the boring other end again, should guarantee that boring table accurately turns round 180 °, after tune, should ensure that boring bar axis overlaps with machining shaft line position, boring two ends inner stopper be boring machine horizontal boring machine, lathe model is TPX6113, ensures axiality 0.03mm;
6th step, turning, car two ends connecting plate, workpiece male half coupling and shoulder face, ensure the perpendicularity 0.1mm of axiality 0.03mm and shoulder face and benchmark;
7th step, pincers, pincers worker deburring and line;
8th step, boring, bores each hole, enters into storehouse.
Process of the present invention is simple, is easy to manufacture, and can ensure crudy and the dimensional accuracy of workpiece, reduces production cost, enhances productivity.
