Description
Technical field
The present invention relates to field of metal surface treatment technology more particularly to a kind of wire surface epithelium processing methods.
Background technology
Element coil is that metal is processed the wire rod to be formed through cold plastic deformation.Metal claims without the plastic deformation of heating
For cold plastic deformation.For example, the processing methods such as punching press, clod wash, cold-drawn, cold-heading, belong to cold plastic deformation.Cold plastic deformation adds
Friction in the processing of work wire rod between wire rod and mold, causes the loss of wire rod bigger.In order to reduce frictional force, reduce mold damage
Consumption and raising production efficiency carry out epithelium processing in wire surface, generate one layer of fine and close film layer, played in process of deformation
Good lubricating action.
Currently, both at home and abroad during Metal Forming used lubricant usually with oil, animal and plant fat, each
The organic compounds such as kind of soaps composition makes that it is attached to metal surface and its lubrication is made using the methods of dipping, sprinkle, brushing
With.Since the physics of conventional lubricant, chemical property are not ideal enough, in blank Cold Drawing Process, needing to do metal surface must
The pretreatment wanted just can guarantee the attachment quantity and firmness of lubricant.So according to traditional processing mode, it is necessary in cold-drawn
Before to blank carry out pickling, washing, secondary washing, oxalic acid, phosphatization, clear water is washed and saponification process, process is various, production efficiency
It is low, and after each cold-drawn, or return to phosphorus wash, wash, neutralizing, saponification, cold-drawn again；Or annealed return to pickling again
From the beginning the pretreatment process before above-mentioned cold-drawn is repeated.From blank to finished product, generally need the several passages of cold-drawn to more than ten of passage,
Cause the repetitive cycling again and again of the above process.Since lubricant effect is bad, pulling capacity is big, and the consumption of power mold is high, it is difficult to and company pulls out,
High processing costs；The surface smoothness of finished product is low, and can be polluted in processing procedure, not environmentally.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found at a kind of wire surface epithelium
Reason method makes it with more the utility value in industry.
Invention content
It is an object of the invention to propose a kind of wire surface epithelium processing method, lubricant effect can be formed on wire rod
Preferable epithelium, and process is simple, processing cost is low, energy-saving and emission-reduction, environmental protection, meets the demand that environmental protection is carried out by country, no industry
Waste.
For this purpose, the present invention uses following technical scheme：
A kind of wire surface epithelium processing method, including step：
(1) wire rod is carried out to pickling 20 minutes in hydrochloric acid trough；
(2) wire rod after pickling is quickly washed in clear water reserviors and dragged for water；
(3) wire rod after washing is put into film agent, is handled 10 minutes at a temperature of 85 DEG C~90 DEG C, it is described
Film agent by weight, including 10~20% sodium metasilicate, 5~10% melamine, 5~10% ammonium carbonate, remaining
For water.
Further, the proportion of the film agent is 1.105~1.109.
Further, the pH value of the film agent is between 10~14.
Further, the ratio of the hydrochloric acid in the hydrochloric acid trough and water is 4：1.
Further, a concentration of the 10%~25% of the hydrochloric acid.
Further, before the step (3), again by the wire rod after washing in the step (2) in clear water
It is quickly washed in pond and dragged for water.
Further, the pH value of clear water is 4~6 in the clear water reserviors.
Beneficial effects of the present invention are：Film agent is without phosphorus, without zinc formula, and environmental protection meets the demand that environmental protection is carried out by country,
Without trade waste, the protective film even compact that is formed on wire rod, excellent adsorption, wire surface lubricity is preferable；And this is matched
The usage amount of the film agent of side is much smaller than the phosphate used in the prior art, and processing cost is low, and process is simple, improves processing
Efficiency.
Specific implementation mode
The technical solution further illustrated the present invention below by specific implementation mode.
The wire surface epithelium processing method of the present invention, includes the following steps：
(1) wire rod is carried out to pickling 20 minutes in hydrochloric acid trough；
(2) wire rod after pickling is quickly washed in clear water reserviors and dragged for water；
(3) wire rod after washing is put into film agent, is handled 10 minutes at a temperature of 85 DEG C~90 DEG C, it is described
Film agent by weight, including 10~20% sodium metasilicate, 5~10% melamine, 5~10% ammonium carbonate, remaining
For water.
Step (1) is used to remove the oxide skin of wire surface, and step (2) is walked for cleaning the remaining hydrochloric acid of wire surface
Suddenly (3) are used to form lubricating protective film in wire surface.As it can be seen that the film agent is without phosphorus, without zinc formula, environmental protection meets country
Carry out the demand of environmental protection, no trade waste, the protective film even compact that can be formed on wire rod, excellent adsorption, wire rod table
Face lubricity is preferable.
Specifically, the proportion of film agent is 1.105~1.109, the pH value of film agent is between 10~14.
In addition, the ratio of the hydrochloric acid and water in hydrochloric acid trough is 4：1, a concentration of the 10%~25% of hydrochloric acid.
In another embodiment, before step (3), again by the wire rod after washing in step (2) in clear water reserviors
It quickly washes and dragged for water, fully to clean the remaining hydrochloric acid of wire surface, and the pH value of the clear water in the clear water reserviors washed twice is 4
~6.
When carrying out wire rod processing using the method for the present invention, wire rod is rolled out from disk circle, the wire rod rolled out is passed through
Correction machine is corrected to linearly, is carried out pickling subsequently into hydrochloric acid trough, is once washed into clear water reserviors, into clear water reserviors secondary water
It washes, into film agent slot overlay film, wire surface can carry out the cold work such as stretching after forming lubricating protective film.
To sum up, the film agent for the without phosphorus no zinc formula that the present invention utilizes meets environmental requirement, and the film agent of the formula
Usage amount is much smaller than the phosphate used in the prior art, and processing cost is low, processing time is short.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and it cannot be construed to limiting the scope of the invention in any way.Based on the explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific implementation modes that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
