Description

Automobile clutch disk hub special-purpose water-based milling liquid and production method

Technical field:

The present invention relates to a kind of metal broaching processing milling liquid, especially a kind of can reduce to greatest extent broaching temperature and broaching firmly, improve broaching working (machining) efficiency, the broaching precision that guarantees workpiece and surface quality and also can prolong the work-ing life of cutter, the automobile clutch disk hub special-purpose water-based milling liquid that reduces cost, satisfies environmental requirement and production method.

Background technology:

Metal broaching processing provides under the condition of power at lathe exactly, by broaching tool metal blank is cut, and makes it to obtain all satisfactory course of processing of shape, size, precision and surface quality.In the Broaching Technology process, smear metal acts on the broaching tool rake face with the pressure up to 2～3GPa, friction generation heat takes place with the workpiece surface of having processed in knife face behind the broaching tool simultaneously, the process zone temperature is sharply risen reach more than 1000 ℃, the cutting pressure on the contacted point of contact of broaching tool and workpiece to be machined surface can make this surface, place bear load up to 5000N/mm ²More than.Therefore, just need to use milling liquid in metal broaching process, milling liquid must have excellent lubrication, cooling property and rust-preventing characteristic, adds phenomenons such as producing local melting welding or broaching tool annealing wearing and tearing man-hour to prevent broaching.

The dish hub is the core component of automobile diaphragm spring clutch friction plate, material is 40Cr, 40Mn, 40CrMn, the diameter of minimum workpiece is about φ 100mm, the diameter of maximum workpiece is about φ 580mm, surface accuracy requirement to the keyway working face is very high, and its working face is by broaching tool broaching processing and manufacturing.Existing dish hub water-based milling liquid has changed that original milling liquid oilness deficiency, cooling property are insufficient, the shortcoming of broaching tool quick abrasion, has satisfied the basic technology performance requriements of dish hub broaching processing.But its cost is still higher relatively and also have distance with the environmental requirement of energy-saving and emission-reduction.

Summary of the invention:

The present invention is in order to solve the existing in prior technology technical problem, provide a kind of can reduce to greatest extent broaching temperature and broaching firmly, improve broaching working (machining) efficiency, the broaching precision that guarantees workpiece and surface quality and can prolong the work-ing life of cutter, the automobile clutch disk hub special-purpose water-based milling liquid that reduces cost, satisfies environmental requirement and production method.
