Abstract
The post-pole jaw for motor-generator set is made up of hot rolled seamless low-carbon steel tube less than N.10 through heating, and fine die forging, and features compact material, stable ferromagnetic properties and low cost.
Description
The present invention relates to a kind of improvement of automotive brushless generator rear polar grab process.
So far, the rotor pole pawl of automotive brushless generator all is to adopt the cast steel molding mode to create, the blank appearance of Sheng Chaning is coarse like this, the fine finishining difficulty is big, and power consumption and waste material are serious, and the raw material of selecting for use during cast steel quite a few be steel scrap, their ferromagnetic property instability, magnetic resistance is big, and the pore of diving in having has influenced dynamically balanced correction.
Task of the present invention is that a kind of new process of making the rotor rear polar grab will be provided, and this method is simple, and the product material after the processing is closely knit, and the fine finishining amount is few, less energy consumption, and cost is low, and its ferromagnetic property improves significantly.
Task of the present invention is to finish in such a way, at first select seamless steel pipe for use, determine the length (and choosing corresponding caliber, wall thickness and weight) of intercepting seamless steel pipe according to the designing requirement of automotive brushless generator, this ferromagnetic material section is with the seamless steel pipe of low-carbon (LC) hot rolling below No. 10, seamless steel pipe section after the intercepting is molded with smart die forging after heating, the rear polar grab that adopts this manufacture method to produce, its size is accurate, waste of material is few, fine finishining is easy, and the ferromagnetism of material is stable, and magnetic resistance is little, cost is low, and quality is good.
The invention will be further elaborated below in conjunction with accompanying drawing.
Fig. 1 is the shape figure of the selected seamless steel pipe of the present invention.
Fig. 2 is the rear polar grab structure chart that the present invention adopts method to make.
Fig. 1 selects low-carbon (LC) hot rolled seamless steel tube below No. 10 for use according to the designing requirement of automotive brushless generator, its caliber, pipe thickness, weight and length are calculated by designing requirement and are obtained, after choosing the caliber suitable, wall thickness and weight with rear polar grab, it is cut into a desired segment length, and the lengths of steel pipes heating of this ferrimagnet is placed on forging forming in the smart mould.
Fig. 2 is that the dimensional tolerance of this rear polar grab is little through the molded rear polar grab of smart die forging, and the fine finishining amount significantly reduces, and avoids the waste of material, and ferromagnetism is stable, and production cost reduces.
