Abstract
The present invention relates to a method for regenerating and processing a diamond circular saw blade base body. The identical hardening treatment can be carried out at two circular surfaces of a diamond circular saw blade base body by a high energy density heating source; the surface of the base body can form a hardening belt; therefore, the stiffness is strengthened; a saw blade is difficult to deflect during the cutting process; the high energy density heating source is a base body focused and regenerated by a plasma beam, a laser beam, an electron beam and sunlight; and the repeated weld frequency is the same with that of a new base body. The present invention utilizes waste base materials as raw materials of regenerating saw blade base bodies, and the needed equipment is simple. The present invention has the advantages of less investment, obvious effect, low composite cost and obvious economic benefit.
Description
The present invention relates to metal surface treating method, specifically relate to handle, the method that its energy overlapping investment is used scrapping the diamond circular saw film base body surface.
Diamond disc is the basic tool that is used to cut stone material such as colored hard rock, and Fig. 1 is the structural representation of diamond disc, as shown in the figure, has uniform serrated slot 2 on the matrix 1 of diamond disc, diamond layer position 3 welding of Buddha's warrior attendant stone 4 and matrix.
The matrix of diamond disc should meet the 65Mn steel of GB1222-84 regulation or steel that mechanical property is not less than 65Mn through quenching and tempering handle obtain hardness and be HRC37-42 after, reach the technical requirements of GB11207-89 regulation through mechanical workout, the Buddha's warrior attendant stone is welded on the diamond layer position of matrix, just can be used for the cutting of flower hard rock.
The thermal treatment process of diamond circular saw film base body, each factory is similar, all be in 810-830 ℃ of heating (useful salt bath furnace heating, also useful resistance furnace heating), after insulation, promptly go into press pressurization cooling about oil cooling to 300 ℃, or after insulation, go into the Quenching press pressurization, high pressure fuel injector cooling back is clamped in (salt stove or band fan tempering stove) 450-480 ℃ tempering in the tempering stove with clamping plate, then with the diamond block welding to the diamond layer position of saw bit matrix, meet the GB11207-89 technical indicator through check, just diamond disc can be contained in the cutting of the enterprising andante material of colored hard rock cutting machine.When the Buddha's warrior attendant stone exhausts, saw blade loses cutting power, take off remaining diamond, the Buddha's warrior attendant stone of burn-oning new again can cut again, and this claims multiple weldering, the multiple weldering number of times of every sheet matrix is relevant with substrate quality, ropy matrix can only weld once again, and the measured matrix of matter can weld 3-5 time again, and the matrix that can not weld again claims to scrap matrix.Diamond circular saw film base body through using for some time with regard to the reason of scrapping is: after using for some time, MATRIX STIFFNESS descends, and causes in cutting process, and saw blade beat amount is big, causes the sheet material became uneven that cuts out even.It also is because of due to its insufficient rigidity less that ropy new matrix welds number of times again.Up to the present,, no matter all make steel scrap at home or abroad and handle, its regeneration can't be come into operation scrapping matrix.
The object of the present invention is to provide and a kind ofly will scrap the method that diamond circular saw film base body carries out manipulation of regeneration, make this matrix through the manipulation of regeneration and the Buddha's warrior attendant stone of burn-oning after, promptly can be used for the cutting of flower hard rock.
The method of diamond circular saw film base body manipulation of regeneration of the present invention is with the high-energy-density heating source two discs of diamond circular saw film base body to be carried out identical hardening treatment, making matrix surface produce austenitic transformation is that martensite forms hardenability band, thereby strengthen its rigidity, make saw blade in cutting process, be difficult for beat, may further comprise the steps:
(1) the clear rust in diamond circular saw film base body surface;
(2) matrix surface leveling;
(3) with the high-energy-density heating source two discs of diamond circular saw film base body are carried out the rapid heating postcooling;
(4) to the matrix finishing after handling;
(5) beat detects.
(1) step was to clean the silt of matrix surface and be bonded at powder slurry on the matrix, and removed the rusty stain of matrix surface; (2) step was that the leveling matrix makes it reach the requirement of GB1222-89 regulation on dull and stereotyped iron pad;
The characteristics of maximum of the present invention are (3) step with the high-energy-density heating source two discs of diamond circular saw film base body to be carried out identical rapid heating postcooling, because when two discs of saw bit matrix are adopted other method heating, can cause the saw blade surface deformation owing to rate of heating is unhappy.The high-energy-density heating source here is meant thermals source such as beam-plasma, laser beam, electron beam, solar light focusing.Can not carry out hardening treatment fully to the whole surface of matrix, otherwise matrix can be out of shape.Matrix surface is processed into hardenability band, Fig. 2, Fig. 3, Fig. 4 are the object lessons that saw bit matrix surface hardening band distributes, and as shown in Figure 2, hardenability band is at saw bit matrix surface molectron triangular in shape; As shown in Figure 3, hardenability band is radiation shapes on the saw bit matrix surface; As shown in Figure 4, hardenability band adds the endless belt on the saw bit matrix surface by the shape of Fig. 3 and forms, and hardenability band can also be spider reticulation or other shape.Hardening treatment to saw bit matrix two discs must be identical, makes the rigidity on its two sides identical, avoids making easy beat of matrix or distortion because of two sides rigidity difference.
With the diamond circular saw film base body that method of the present invention was handled, it is identical with new diamond circular saw film base body that it welds number of times again.Every sheet matrix can be handled twice with method of the present invention at least.Also can handle new matrix with method of the present invention, improve it and weld number of times again.
The present invention compared with prior art has following advantage: (1) utilizes and scraps matrix do regeneration saw bit matrix raw material, and material cost is extremely low; (2) need not manufacturing procedures such as blanking, fluting, Q-tempering, face machined flat, cut down finished cost greatly; (3) to weld number of times again identical with protocorm basically for the regeneration matrix, if regenerate twice with method of the present invention, then a sheet matrix equals two sheet matrixes.(4) comprehensive cost is extremely low, remarkable in economical benefits; (5) equipment of Xu Yaoing is simple, less investment, instant effect; (6) biggest advantage of the present invention is to adopt rapid heating to carry out hardening treatment, and the saw bit matrix surface is out of shape minimum in treating processes.
Further narrate method of the present invention below in conjunction with embodiment.
