Abstract
The invention discloses an automobile bearing retainer production technology which is characterized by comprising the technological steps of blanking, retainer blank forging, surface treatment, turning and surface galvanization. According to a bearing retainer produced through turning instead of grinding, the depth of parallelism of two ends is high, an inner hole has no conicity out-of-tolerance phenomenon, operation is easy, convenient and safe, the production process is short, production efficiency is high, the cost is low, and the application and popularization value is provided.
Description
Technical field
The present invention relates to a kind of machining process, particularly a kind of automobile bearing guard ring production technology.
Background technology
Automobile bearing guard ring is the strength member on automobile axle shaft, it is a ring-shape accessory, the depth of parallelism of two ends two plane requires high, bearing tolerances is little, conventional production technology is after rough turn both ends of the surface and endoporus, then to grinding machine, grinds endoporus and end flat, during inner hole grinding, easily occur bellmouth and Burn defect, grinding plane production efficiency is low, cost is high.
Summary of the invention
The object of the invention is the above-mentioned weak point in order to overcome prior art, and provide a kind of stable and reliable product quality of processing, qualification rate is high, the automobile bearing guard ring production technology that production efficiency is high, cost is low.
For achieving the above object, the concrete technology step of the present invention's employing is as follows:
1. blanking: according to design size, utilizes sawing machine or cutting machine to cut bar;
2. forge guard ring blank: according to design size, bar is swaged into guard ring blank;
3. surface treatment: the guard ring blank through formed by forging is put into shot-blasting machine Shot Blasting, removes oxide skin and rusty stain;
4. turnery processing: adopt special jaw to clamp rough turn end face and cylindrical, rough turn, finish turning endoporus, finish turning one transverse plane, turn around thick, finish turning other end and cylindrical, car inner bore chamfering;
5. plating zinc on surface: workpiece is loaded plating line, effects on surface carries out zinc-plated process.
The present invention is owing to adopting above process, and the bearing retaining ring produced with the method for car generation mill, the two ends depth of parallelism is high, endoporus zero draft off-gage phenomenon, easy and simple to handle, safety, and production procedure is short, and production efficiency is high, cost is low, has application value.
Detailed description of the invention
1., according to design size, utilize sawing machine or cutting machine to cut bar;
2., on special forging machine tool, according to design size, bar is swaged into guard ring blank;
3. the guard ring blank through formed by forging is put into shot-blasting machine Shot Blasting, remove oxide skin and rusty stain;
4. adopt special jaw to clamp rough turn end face and cylindrical, rough turn, finish turning endoporus, finish turning one transverse plane, turn around thick, finish turning other end and cylindrical, car inner bore chamfering;
5. workpiece is loaded plating line, effects on surface carries out zinc-plated process.
