Abstract
The technological process of forming pawl pole includes the steps of cutting stock, hot die forging, cold extruding to cut overlap, finish machining, and surface lubrication. It has the advantages of hot forging, cold extruding, die-forging and machining and short production process, and the pawl pole product has compact structure, no shrink hole and slag hole, stable chemical property and high strength.
Description
The present invention relates to the production method of the pawl utmost point that a kind of automobile current generator uses.
At present, the claw pole for automobile generator of domestic production is with hot investment casting and Sheet Metal Forming Technology production, Sheet Metal Forming Technology is subjected to the restriction of need with large-scale forging equipment, and the dynamic balancing of the disadvantages affect rotor that the claw moulding is not full of, thereby generator for electricity generation efficient is reduced, the as easy as rolling off a log generation shrinkage cavity of the pawl of hot investment casting, loose, it is inhomogeneous that defectives such as slag and chemical composition instability easily cause taste to lead power, magnetic property descends, influence the dynamic balancing of rotor, and finally cause generator for electricity generation efficient to reduce.
The objective of the invention is to propose a kind of hot forging and cold extruding formation process for pawl pole of automobile generator in order to overcome above-mentioned defective.
Technical scheme of the present invention is as follows: hot forging and cold extruding formation process for pawl pole of automobile generator is characterized by: have following technological process: a. blanking, as required, raw pieces 1 is sawed or cut into to raw material; B. heat precompressed, raw pieces 1 is dropped in the heating furnace be heated to 1050 ℃-1150 ℃, flatten into pre-press 2 then; C. forge hot is put into hot-forging die preformed with pre-press 2, forms hot forging 3; D. hot rolling is put into the hot rolling of hot rolling mould with hot forging 3, forms finish-forging spare 4; E. cut overlap, the cylindrical overlap of finish-forging spare 4 and the clout of head are excised; F. annealing is with finish-forging spare 4 annealing of cutting behind the overlap; G. boring, with cut overlap, annealing after finish-forging spare 4 hole into preformed member 5; H. the oxide skin of preformed member 5 is removed in surface treatment, carries out surface lubrication again and handles, and is used to increase the extremely lubricating coefficient on surface of pawl; I. cold-extruded, with the hydraulic press cold extrusion after surface treatment preformed member 5 and the hole is extruded into the drawing requirement, form profiled member 6; J. cold forging with profiled member 6 cold forgings, makes the extremely outer rounded corner moulding of pawl; K. fine finishining according to the product size needs, is carried out fine finishining to the hole of the profiled member behind the cold forging 6, positive antiplane, cylindrical, interior inclined-plane etc., makes it reach the drawing requirement, forms final shaping unit spare 7.
In the most preferred embodiment of the present invention:
Described heating-up temperature is 1100 ℃, and is a high temperature heating;
In the time of around the described pawl utmost point convex coil non-slip process and skewed slot need being arranged, after becoming profiled member 6, cold-extruded increases by one cold-extrusion technology again.
Described surface lubrication is handled, and adopts the surperficial means that are coated with the polymeric lubricant layer, or with 190 ℃ of processing of preformed member 5 heating.
The present invention combines forge hot and cold-extruded, die forging and mach advantage in one, makes the moulding of the pawl utmost point with short production procedure, and forming claw polaron ingredient stability, no shrinkage cavity, and slag blister and strength-enhanced, generator for electricity generation power is significantly improved.
Below in conjunction with process drawing most preferred embodiment of the present invention is described:
