Abstract
This invention relates to the laser heat treatment technology field of metallic substance.
This invention CO
2After the cutting edge of sorbitic cutter of laser beam centering Tempering or cutting die carries out the transformation hardening processing, the toughness of present cutter and cutting die and the problem that hardness can not get both have been solved well, improved their performance, make them can not only bend 90 ° and do not have crackle, cutting edge has enough hardness again, be enhanced about more than once work-ing life, and expanded the use range of cutter and cutting die, the corresponding range of product that increased.
This inventive method is simple, and is easy to operate, with low cost, and the development of printing, packing business and shoe industry is had immeasurable significance.
Description
This invention relates to the laser heat treatment technology field of metallic substance.
All kinds of cutting dies that steel wire cutter of print at present, packaging industry being used and shoe industry are used all are to be material with medium carbon steel, heat-treat and get with the method for Q-tempering, promptly will send into temperature with steel earlier is 840 ℃-850 ℃ process furnace austenitizing, then with water flowing refrigerative pig iron plate quenching and pressing, send into the tempering stove tempering again, the control tempering temperature can obtain the product of three kinds of hardness specifications: (1) soft cutter, hardness is HRC28-32, (2) hard cutter in, hardness is HRC38-42, (3) hard cutter, hardness is HRC46.Hard cutter result of use is better, but toughness is not enough, bending 90 ° can ftracture, though soft cutter can bend because hardness is low, result of use is not good, life-span is lower, in hard cutter fall between, but work-ing life and bending performance still can not satisfy in the industrial production and press for, seriously hinder the technical progress of printing, packaging industry and shoe industry and the update of product, and directly influenced the foreign exchange earning of China.
This invention provide in order to address the above problem exactly to being that the cutter or the cutting die of material carries out new heat treating method with medium carbon steel.
This essence of an invention is that the matrix to cutter or cutting die carries out laser transformation hardening to cutting edge again and handles on the basis of tempered sorbite, has solved the toughness of cutter and cutting die and the problem that hardness can not get both dry straightly.
The advantage of this invention is that method is simple, easy to operate, with low cost, functional through cutter or cutting die that this novel method was handled, it not only has good toughness, bend 90 ° and do not have crackle, cutting edge also has enough hardness, be enhanced about more than once than originally work-ing life, expanded the use range of various cutters and all kinds of cutting dies widely, increased the kind of corresponding product, technical progress and the model change that promotes printing, packaging industry and shoe industry there is immeasurable significance, also makes fruitful contribution for China's foreign exchange earning.
Fig. 1 is the process flow sheet of this invention.
Wherein: 1, middle carbon ribbon steel.
2, the band steel of tempered sorbite matrix.
3, coat at blade.
4, blade carries out the laser transformation hardening processing.
5, clean last slushing oil, packing.
The technological process process is: be that to send temperature to be 840 ℃-850 ℃ heating furnace heating 1 minute for the middle carbon ribbon steel of 0.35%-0.50% with phosphorus content at first, then with logical water-cooled pig iron plate quenching and pressing, send into again temperature and be 560 ℃ tempering furnace tempering 2 minutes, make the band steel matrix become tempered sorbite, at this moment the matrix of cutter has good toughness, coats at the cutting edge of cutter then to absorb CO2The coating of laser is used CO more afterwards2The laser beam of laser instrument emission carries out transformation hardening and processes facing to the cutting edge irradiation of cutter. The incident power density of this laser beam is 2-3 * 103W/cm
2Irradiation time is 0.05s-0.2s, and expand processing through the broadband, the light beam irradiates width is 10mm-15mm, cutter is made at the uniform velocity traveling priority with the speed of 5-20mm/s in the width of laser beam irradiation, be the heating that prevents the non-blade port position and the correct austenitizing of guaranteeing cutting edge, and the angle of incoming laser beam remains on the width of cutter and becomes 0 ° ± 5 °, become 90 ° ± 5 ° with the length direction of cutter, become 90 ° ± 5 ° range with the thickness aspect of cutter. After blade is processed through transformation hardening, become cryptocrystal mixed type martensite, therefore cutter has good performance: (1) edge hardness is HRC53-57, (2) the cutting edge hardened-depth is 0.20-0.25mm, (3) 90 ° of flawlesses of static bending occur, (4) LASER HEAT TREATMENT tool setting edge surface fineness does not have impact, and (5) were enhanced about more than once than originally service life. Clean at last cutter and coat, first-class antirust oil is packed namely complete.
Embodiment:
The steel wire cutter of using with printing, packaging industry is an example.
40A or 50A band steel with rolling carries out Q-tempering thermal treatment with usual method to it earlier, send into temperature and be 840 ℃-850 ℃ process furnace heating 1 minute, send into temperature after the cooling and be 560 ℃ tempering stove tempering 2 minutes, making the band steel matrix is tempered sorbite, put the first edge on a knife or a pair of scissors then, again with the steel wire cutter of a rolling or the tempered sorbite matrix that becomes with thyristor speed control and gear-driven clamping device clamping, make blade up, and do at the uniform velocity with the speed of 5-20mm/s that straight line moves, in moving process, at first blade is coated special absorption CO by simple funnel device
2The coating of laser is then by CO
2Laser apparatus emitted laser bundle is facing to the blade irradiation, and the incident power density of this laser beam is 2-3 * 10
3W/cm
2Beam irradiating time is 0.05s-0.2s, width of light beam is 10mm-15mm, is heating that prevents the non-blade port position and the correct austenitizing that guarantees cutting edge, and incoming laser beam remains on the width of cutter with the angle of steel wire cutter and becomes 0 ° ± 5 °, become 90 ° ± 5 ° with the length direction of cutter, become with the thickness direction of cutter within 90 ° ± 5 ° the scope, blade through transformation hardening thermal treatment after, clean cutter and coat, last slushing oil, pack at last.
