Problems solved by technology

The existing water-based broaching fluid for hubs has changed the shortcomings of the original broaching fluids, such as insufficient lubricity, insufficient cooling, and fast broach wear, and meets the basic process performance requirements for hub broaching.
However, its cost is still relatively high and there is still a distance from the environmental protection requirements of energy saving and emission reduction.

Embodiment 1

[0041] Raw materials and weight percentages are as follows: phytic acid 1.2-1.8%, sodium benzoate 3-5%, triethanolamine 5.5-6.5%, sodium carbonate 1.8-2.2%, sodium thiosulfate 0.8-1.2%, polyethylene glycol 7-9 %, glycerol 9-11%, sulfonated castor oil 2.5-3.5%, oleic acid 1.5-2.5%, alkylphenol polyoxyethylene ether 1.5-2.5%, isothiazolinone 0.4-0.6%, deionized Water 56-62%.

[0042] Each raw material can be selected within the weight range, so that the weight sum is 100%.

[0043] The production method is as follows:

[0044] a. First add the calculated amount of deionized water, phytic acid, sodium benzoate, and triethanolamine into the reaction kettle in turn, start the stirrer, and stir at room temperature for 1 hour at a speed of 200 rpm;

[0045] b. Add the calculated amount of sodium carbonate, sodium thiosulfate, polyethylene glycol, glycerol, sulfonated castor oil, oleic acid, alkylphenol polyoxyethylene ether, and isothiazolinone into the reactor successively, And h...

Embodiment 2

[0049] The production method is the same as in Example 1, except that the raw materials and weight percentages are as follows: phytic acid 1.5%, sodium benzoate 4%, triethanolamine 6%, sodium carbonate 2%, sodium thiosulfate 1%, polyethylene glycol 8%, glycerol Alcohol 10%, sulfonated castor oil 3%, oleic acid 2%, alkylphenol polyoxyethylene ether 2%, isothiazolinone 0.5%, deionized water 59%.

[0050] Product Appearance: Purple viscous transparent liquid.

[0051] The products of Example 1 and Example 2 of the present invention are formulated with 6% to 8% working fluid, put into the broaching fluid tank of the broaching machine, and spray the broach at the inlet and outlet of the broach simultaneously by means of pumping and circulation , for lubrication and cooling of broaching. Applied to the broaching of the keyway hole of the hub of the automobile clutch, it can minimize the broaching temperature and broaching force, improve the broaching efficiency, the broaching accur...

Abstract

The invention discloses a water-based broaching liquor for automobile clutch disk hub which can reduce broaching temperature and force to maximum extent, improves processing efficiency of broaching, ensures broaching precision and surface quality, prolongs life of cutting tool, reduces cost, satisfies environmental protection requirement. Raw materials of specialized water-based broaching liquor and corresponding weight percentage are phytic acid 1.2-1.8%, sodium benzoate 3-5%, triethanolamine 5.5-6.5%, sodium carbonate 1,8-2.2%, hyposulfite of soda 0.8-1.2%, polyethyleneglycol 7-9%, glycyl alcohol 9-11%, sulfonated castor oil 2.5-3.5%, oleic acid 1.5-2.5%, alkyl phenol polyethenoxy ether 1.5-2.5%, 2-methyl-3(2H)-isothiazolone 0.4-0.6%, de-ionized water 56-62%. The production method is synthesis with stirring under normal temperature - medium temperature - normal temperature.

Description

Technical field: [0001] The invention relates to a broaching fluid for metal broaching, in particular to a broaching fluid that can reduce the broaching temperature and broaching force to the greatest extent, improve the broaching efficiency, ensure the broaching accuracy and surface quality of the workpiece, and prolong the tool life. A special water-based broaching fluid for automobile clutch disc hubs and a production method that have a long service life, reduce costs, and meet environmental protection requirements. Background technique: [0002] Metal broaching is a process in which the metal blank is cut by a broach under the condition of power provided by the machine tool, so that the shape, size, precision and surface quality meet the requirements. During the broaching process, chips act on the rake face of the broach with a pressure of up to 2 to 3 GPa, and at the same time, the flank face of the broach and the surface of the processed workpiece generate heat by fric...
