Abstract
This invention discloses a forge technology of polar claws of car generators, which selects a raw material and cuts it to blank bar sections then to heat them to over 900deg.C to be put in three dies to be forged and molded by a close single-point press to get the products of polar claws.
Description
Affiliated technical field
The present invention relates to a kind of improvement of pole jaw of car electricity generator manufacture method, it both can be used for automobile the brush generator, also can be used for automotive brushless generator.
Technical background
Utmost point pawl is an important spare part of automobile current generator, normally adopt casting method production, sand holes can appear, the pore phenomenon, and material is also unstable, though cold extrusion method is improving qualitatively, but its cost height, therefore there is the people that correlation technique is proposed improvement project, for example select qualified bar for use about mentioning in " manufacture method of pole jaw of car electricity generator " Chinese patent CN99111090.0 number, be heated to forging temperature, to heat bar with forging equipment, in the blocking mould, be swaged in advance and be suitable for hot-forming blank, again above-mentioned blank is heated to hot pressing temperature, hot-forming with hot pressing die, use the die-cut burr of punch press then.This manufacture method needs heating for multiple times, the manufacturing procedure complexity, and employing equipment is more, and work efficiency is low, the production cost height.
Summary of the invention
Task of the present invention is the forging and pressing producing technology that a kind of pole jaw of car electricity generator will be provided, and the operation of this manufacture method is simple, the device efficiency height of use, constant product quality, low production cost.
Task of the present invention is to finish in such a way, the concrete steps of the forging and pressing producing technology of this pole jaw of car electricity generator are: 1, selection first pressing: at first select suitable blank for use, through suitably being placed in first mould after the heating, through the first forging and pressing moulding of closed type single point press, obtain finished product just.2, forging and pressing moulding: the first finished product of moulding for the first time is placed in the 2nd mould once more,, obtains the semi-finished product of utmost point pawl through the moulding of forging and pressing once more of closed type single point press.3, forging forming: the semi-finished product of moulding for the second time are placed on again in the 3rd mould, and obtain utmost point pawl finished product through after the forging and pressing moulding of closed type single point press.This forging and pressing producing technology is more reasonable, easy, does not need heating for multiple times, and the quality of product is also more stable, owing to adopt the speed of closed type single point press special equipment fast, so work efficiency significantly improves, production cost of products reduces greatly.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is a pole jaw of car electricity generator forging and pressing producing technology flow chart of the present invention.
Embodiment
As we know from the figure, the forging and pressing producing technology of this pole jaw of car electricity generator is to carry out selection, first pressing earlier, select suitable raw material for use, and their are cut off become suitable blank section bar, they are heated to more than 900 ℃ again, be placed on then in first mould, use closed type single point press to forge and press moulding for the first time, thereby obtain finished product just; Then be forging and pressing, moulding, and then the first finished product of moulding for the first time is placed in second mould, pass through the forging and pressing moulding of closed type single point press once more, obtain the semi-finished product of utmost point pawl; Be forging and pressing, moulding at last, it is that semi-finished product with the moulding second time are put in the 3rd mould and go, again through obtaining the finished product of utmost point pawl after the forging and pressing moulding of closed type single point press.This manufacturing process adopts one to three closed type single point press that operating efficiency is quite high, and production cost reduces, and output significantly improves, and the steady quality of product, reliable.
Claims (1)
1, a kind of forging and pressing producing technology of pole jaw of car electricity generator, it is characterized in that: select suitable raw material earlier for use, and their are cut off become suitable bad section bar of hair, they are heated to more than 900 ℃, be placed on then in first mould, use closed type single point press to forge and press for the first time, obtain finished product just, and then the first finished product of the moulding first time is placed in second mould, pass through the forging and pressing moulding of closed type single point press once more, become the semi-finished product of utmost point pawl, at last semi-finished product are put in the 3rd mould and go, obtain the finished product of utmost point pawl again through the forging forming of closed type single point press.
