Abstract
A laser processing battery rod punching process belongs to a processing process of a laser surface reinforced battery rod punching working tape. The process comprises removing oil stains on the battery punch rod, selecting a laser treatment mode of the battery punch rod, determining technological parameters and a scanning starting point of the laser treatment of the punch rod, treating and cooling the punch rod by using laser, tempering the punch rod, and cooling the punch rod to room temperature. The battery punch rod treated by the method has no deformation, the toughness and the wear resistance of the battery punch rod are improved, and the service life of the battery punch rod can be greatly prolonged.
Description
The invention belongs to the technology of laser surface intensified battery impact bar work zone.
Existing battery impact bar is the stamping forming punch of whole zinc tube.It is by W
18Cr
4V
1Or W
6Mo
5Cr
4V
2Rapid steel is made.Under the cold punching condition, dash about 2-3 ten thousand times mean life of rod.The whole nation more than 320 families of existing battery production factory produce about 25,000,000,000 of drying battery per year, thereby improve and occupy very consequence the work-ing life of dashing rod in the battery production industry.Battery impact bar in use, its flange work zone constantly is subjected at a high speed, powerful shock action, causes its cutting edge cracking thus and loses efficacy.At present, adopt the thermal treatment process of+three high temperings that quench to strengthen battery impact bar.The work-ing life of the battery impact bar of this art breading is lower, and its cutting edge is easy to crack, and is yielding in the heat treatment process.
The white shore of Chongqing mechanical investigations institute, on " metal heat treatmet " magazine of editing and publishing in 1986 in the Beijing Electromechanical Research Inst, " research of cold-punching mold Laser Heat Treating in China " paper of delivering does not relate to uses battery impact bar by laser treatment.
The present invention is intended at above-mentioned the deficiencies in the prior art, a kind of battery impact bar laser processing technique is provided, this technology can make the battery impact bar after the processing not have distortion, and can improve the obdurability and the wear resistance of its cutting edge, thereby increases substantially the work-ing life of battery impact bar.
Technical scheme of the present invention is to utilize the cutting edge of light laser rapid heating battery impact bar.Make it from cooling or pressure cool to room temperature then.Again it is carried out high tempering, cooling.
The technology that realizes the laser reinforcing battery impact bar is by earlier the rapid steel bar being machined to battery impact bar, when scanning first, light laser dashes the location, edge, termination of rod at this, make cutting edge rapid heating and cooling with laser scanning, the high tempering that rod carries out 1-3 time once more that dashes after the laser treatment is formed towards excellent work zone.Its technology is:
1) greasy dirt of removal battery impact bar termination.Select gasoline or kerosene or dehydrated alcohol for use, at room temperature deoil, time 0.5-5 minute.
2) laser treatment has following three kinds of different modes
A. when HRC 〉=64, with carbonaceous black agent melanism battery impact bar cross cut end (of a beam).Melanism is coated with layer height 0.01-10 μ m, width 2.0-5.0mm.
B. when HRC 〉=65, with the tackiness agent mixing W of carbon containing one hydrogen

5The super-hard high-speed steel powder.It is covered on the surface, work zone of battery impact bar.Its tectum height 10
-2-10
-1Mm, width 2.0-5.0mm.
C. when HRC 〉=66, the battery impact bar that deoils when light laser is handled, is directly sent into W with powder feeder to the molten bath
12Cr
4V
4Co
5Powder.Powder feed rate 0.01～100g/ second.
3) battery impact bar is placed on the working face of laser machine.Move this processing machine, make laser beam aim at certain point on the edge line of battery impact bar termination.This point is the sweep starting point of light laser.
4) start the continuously adjustable laser apparatus of output rating, make laser beam pass through direct alignment scanning starting point after the beam treatment system, from then on begin scanning.By the light laser rapid scanning, the battery impact bar termination is strengthened.Its laser power 10

5) allow the battery impact bar of LASER HEATING be as cold as room temperature certainly.Or be that the pressurized air of 0.1-10MPa is forced cooling with pressure.Compressed-air actuated jet area 0.5-20mm
2, it is apart from laser scanning point 5-50mm.
6) again battery impact bar is complied with identical tempering process continuous high temperature tempering 1-3 time.Its tempering process is: tempering temperature 350-650 ℃, and rate of heating 10
